    The Late Miocene Muaraenim Formation in southern Sumatra contains thick coal sequences, mostly of low rank ranging from lignite to sub-bituminous, and it is believed that these thick low rank coals are the most prospective for the production of coal seam gas (CSG), otherwise known as coalbed methane (CBM), in Indonesia. As part of a major CSG exploration project, gas exploration drilling operations are being undertaken in Rambutan Gasfields in the Muaraenim Formation to characterize the CSG potential of the coals. The first stage of the project, which is described here, was designed to examine the gas reservoir properties with a focus on coal gas storage capacity and compositional properties. Some five CSG exploration boreholes were drilled in the Rambutan Gasfield, south of Palembang. The exploration boreholes were drilled to depths of {proportional_to} 1000 m into the Muaraenim Formation. Five major coal seams were intersected by these holes between the depths of 450 and 1000 m. The petrography of coal samples collected from these seams showed that they are vitrinite rich, with vitrinite contents of more than 75% (on a mineral and moisture free basis). Gas contents of up to 5.8 m{sup 3}/t were measured for the coal samples. The gas desorbed from coal samples contain mainly methane (CH{sub 4}) ranging from 80 to 93% and carbon dioxide (CO{sub 2}) ranging from 6 to 19%. The composition of the gas released into the production borehole/well is, however, much richer in CH{sub 4} with about 94 to 98% CH{sub 4} and less than 5% CO{sub 2}. The initial results of drilling and reservoir characterization studies indicate suitable gas recovery parameters for three of the five coal seams with a total thickness of more than 30 m. (author)

    Modern computer systems are increasingly complex, with ever changing bottlenecks. This makes it difficult to ensure consistent performance when porting software, or even running it. Adaptivity, ie, switching between program variations, and dynamic recompilation have been suggested as solutions....... Both solutions come at a cost; adaptivity issues a runtime overhead and requires more design effort, while dynamic recompilation takes time to perform. In this project, we plan to investigate the possibilities, limitations, and benefits of these techniques. This abstract covers our thoughts on how...

    Levitt, Clinton J.

    I investigate the importance of learning in oil and gas exploration. I developed a tractable dynamic structural model of oil and gas exploration in which firms gradually learn about the productive qualities of different regions through exploratory drilling. Exploratory drilling is modelled...... as an information-gathering process in which each new exploratory well provides information concerning the profitability of drilling additional wells in a given area. The model is geographically based and accounts for the heterogeneity in the characteristics of oil and gas deposits that can exist across large...... the observed geography of exploratory drilling. The broader implications of my model indicate that the structure of information has important effects on drilling behaviour, and that these effects vary, depending on the specific characteristics of the regions being explored....

    This publication describes the major components of the research and development programs of the Department of Energy`s Office of Natural Gas and Petroleum Technology. These programs are commonly referred to collectively as the `Oil and Gas Program.` This document provides customers with a single source of information describing the details of the individual technology program components. This document reflects the results of a planning cycle that began in early 1996 with the development of a scenario analysis for the programs, followed by the development of the coordinated strategic plan. The technology program plans, which are the most recent products of the planning cycle, expand on the program descriptions presented in the coordinated strategic plan, and represent an initial effort to coordinate the Oil and Gas Program exploration and production programs and budgets. Each technology program plan includes a `roadmap` that summarizes the progress of the program to the present and indicates its future direction. The roadmaps describe the program drivers, vision, mission, strategies, and measures of success. Both the individual technology program plans and the strategic plan are dynamic and are intended to be updated regularly.

    The steps that lead to the production of oil and gas are diverse, complex and costly. They are diverse, because the detection of oil and gas involves input from many specialties, ranging from geology to reservoir engineering. They are complex, as shown by the development of the job of the petroleum architect, who coordinates all the operations. They are costly, as the investments for exploration and production represent more than half of all investments in the oil and gas sector. Moreover, exploration is a risky activity, both from the technical and financial viewpoint: only one well in five produces marketable oil. Meanwhile, the areas for exploration and production are spread throughout the world. This book provides a complete overview of the stakes and challenges involved in oil and gas exploration and production. Following a historical review and a survey of the markets, the technical phases are covered, as are the evaluation of reserves, the estimation of investments and costs, the decision-making and control processes, and the accounting, legal and contractual environment for these activities. The book concludes with a discussion of the role of safety, and of environmental and ethical issues. This work, which is designed for readers concerned with the various aspects of the oil and gas upstream sector, is accessible to all. Contents: 1. Petroleum: a strategic product. 2. Oil and gas exploration and production. 3. Hydrocarbon reserves. 4. Investments and costs. 5. Legal, fiscal and contractual framework. 6. Decision-making on exploration and production. 7. Information, accounting and competition analysis. 8. Health, safety, the environment, ethics. Bibliography. Glossary. Index

  11. Canadian incentives for oil and gas exploration. [Applicability to USA

    1980-04-01

    During the 1970s a number of different exploration and production incentive programs were put in place in Canada, in particular in the Province of Alberta, Canada's principal oil- and gas-producing province. The DOE/RA is evaluating Canadian incentives for oil and gas exploration, and this study is intended to provide information that will help guide DOE/RA in determining the applicability of Canadian incentive programs in US energy policy. The study describes and documents the fiscal structure in which the Canadian oil industry operates. The incentive features of pricing policy, taxation policy, and provincial royalty systems are discussed. A principal focus of the study is on one of the most important of Canada's specific incentive programs, the Alberta Exploratory Drilling Incentive Credit Program (EDICP). The study describes and evaluates the effect of the EDICP on increased oil and gas exploration activity. Similarly, the study also reviews and evaluates other specific incentive programs such as the Alberta Geophysical Incentive Program, Frontier Exploration Allowances, and various tar sand and heavy oil development incentives. Finally the study evaluates the applicability of Canadian incentives to US energy policy.

    Korea's first gas hydrate research project was launched in 1996 to study the gas hydrate potential in the Ulleung Basin of the East Sea. It involved a series of laboratory experiments followed by a preliminary offshore seismic survey and regional reconnaissance geophysical and marine geological surveys. The bottom simulating reflector (BSR) was interpreted to show wide area distribution in the southern part of the Ulleung Basin, and its average burial depth was 187 m below the sea floor in the East Sea. A three-phase 10-year National Gas Hydrate Development Program was launched in 2004 to estimate the potential reserves in the East Sea. It will involve drilling to identify natural gas hydrates and to determine the most optimized production methods. Drilling sites were proposed based on five indicators that imply gas hydrate occurrence, notably BSR, gas vent, enhanced seismic reflection, acoustic blanking and gas seeping structure. The UBGH-X-01 gas hydrate expedition in the East Sea Ulleung Basin involved 5 logging while drilling (LWD) surveys at three high priority sites. One wire line logging was implemented at the site of the UBGH09. A total 334 m of non-pressurized conventional cores and 16 pressure cores were obtained in late 2007. The UBGH-X-01 was successfully completed, recovering many natural samples of gas hydrate from 3 coring sites in the East Sea. 7 refs., 12 figs.

    This report describes the status of developing analytical methods to account for the organic constituents in Hanford waste tanks, with particular emphasis on those tanks that have been assigned to the Flammable Gas Watch List. Six samples of core segments from Tank 101-SY, obtained during the window E core sampling, have been analyzed for organic constituents. Four of the samples were from the upper region, or convective layer, of the tank and two were from the lower, nonconvective layer. The samples were analyzed for chelators, chelator fragments, and several carboxylic acids by derivatization gas chromatography/mass spectrometry (GC/MS). The major components detected were ethylenediaminetetraacetic acid (EDTA), nitroso-iminodiacetic acid (NIDA), nitrilotriacetic acid (NTA), citric acid (CA), succinic acid (SA), and ethylenediaminetriacetic acid (ED3A). The chelator of highest concentration was EDTA in all six samples analyzed. Liquid chromatography (LC) was used to quantitate low molecular weight acids (LMWA) including oxalic, formic, glycolic, and acetic acids, which are present in the waste as acid salts. From 23 to 61% of the total organic carbon (TOC) in the samples analyzed was accounted for by these acids. Oxalate constituted approximately 40% of the TOC in the nonconvective layer samples. Oxalate was found to be approximately 3 to 4 times higher in concentration in the nonconvective layer than in the convective layer. During FY 1993, LC methods for analyzing LWMA, and two chelators N-(2-hydroxyethyl) ethylenediaminetriacetic acid and EDTA, were transferred to personnel in the Analytical Chemistry Laboratory and the 222-S laboratory

    As the Congress declared in the Outer Continental Shelf Lands Act the natural gas and oil production from the Outer Continental Shelf constitutes an important part of the Nation's domestic energy supply. Federal offshore minerals are administered within the Department of the Interior by the Minerals Management Service (MMS), which provides access to potential new sources of natural gas and oil offshore by conducting lease sales. Each year, on or before March 31, the MMS presents to Congress a fiscal year annual report on the Federal offshore natural gas and oil leasing and production program. In FY 1991, this program was the third largest producer of non-tax revenue for the US Treasury, contributing more than $3 billion. This report presents Federal offshore leasing, sales, production, and exploration activities, and environmental monitoring activities

    Gas hydrates sediments have the potential of providing a huge amount of natural gas for human use. Hydrate sediments have been found in many different regions where the required temperature and pressure conditions have been satisfied. Resource exploitation is related to the safe dissociation of the gas hydrate sediments. Basic depressurization techniques and thermal stimulation processes have been tried in pilot efforts to exploit the resource. There is a growing interest in gas hydrates all over the world due to the inevitable decline of oil and gas reserves. Many different countries are interested in this valuable resource. Unsurprisingly, developed countries with limited energy resources have taken the lead in worldwide gas hydrates research and exploration. The goal of this research project is to collect information in order to record and evaluate the relative strengths and goals of the different gas hydrates programs throughout the world. A thorough literature search about gas hydrates research activities has been conducted. The main participants in the research effort have been identified and summaries of their past and present activities reported. An evaluation section discussing present and future research activities has also been included.

    The most important resources to fulfill today’s energy demands are fossil fuels, such as oil and natural gas. When exploiting hydrocarbon reservoirs, a detailed and credible model of the subsurface structures to plan the path of the borehole, is crucial in order to minimize economic and ecological risks. Before that, the placement, as well as the operations of oil rigs need to be planned carefully, as off-shore oil exploration is vulnerable to hazards caused by strong currents. The oil and gas industry therefore relies on accurate ocean forecasting systems for planning their operations. This thesis presents visual workflows for creating subsurface models as well as planning the placement and operations of off-shore structures. Creating a credible subsurface model poses two major challenges: First, the structures in highly ambiguous seismic data are interpreted in the time domain. Second, a velocity model has to be built from this interpretation to match the model to depth measurements from wells. If it is not possible to obtain a match at all positions, the interpretation has to be updated, going back to the first step. This results in a lengthy back and forth between the different steps, or in an unphysical velocity model in many cases. We present a novel, integrated approach to interactively creating subsurface models from reflection seismics, by integrating the interpretation of the seismic data using an interactive horizon extraction technique based on piecewise global optimization with velocity modeling. Computing and visualizing the effects of changes to the interpretation and velocity model on the depth-converted model, on the fly enables an integrated feedback loop that enables a completely new connection of the seismic data in time domain, and well data in depth domain. For planning the operations of off-shore structures we present a novel integrated visualization system that enables interactive visual analysis of ensemble simulations used in ocean

    Although the gas centrifuge process for uranium enrichment is often referred to as a ''new technology,'' it has been under development for approximately 25 years to bring it to its current state of deployment. Centrifuges are now being installed in a new gas centrifuge enrichment plant (GCEP) at Portsmouth, Ohio. The objective of this new plant was to provide additional U.S. uranium enrichment capacity at a production cost comparable to the U.S. diffusion process but requiring much less power per separative work unit (SWU) produced. The current, commercial scale centrifuge technology being installed meets that objective. The objective for new U.S. enrichment capacity has changed. The objective is not to provide more SWUs but to provide cheaper SWUs. The objective is to make the U.S. uranium enrichment enterprise competitive on the international market. Where the U.S. at one time supplied virtually all of the free world SWU demand, the U.S. market share has now dropped to approximately 35% of the foreign free world market. The Advanced Gas Centrifuge (AGC) program provides an avenue for making the U.S. the economically attractive, reliable enrichment supplier

    For planning the operations of off-shore structures we present a novel integrated visualization system that enables interactive visual analysis of ensemble simulations used in ocean forecasting, i.e, simulations of sea surface elevation. Changes in sea surface elevation are a good indicator for the movement of loop current eddies. Our visualization approach enables their interactive exploration and analysis. We enable analysis of the spatial domain, for planning the placement of structures, as well as detailed exploration of the temporal evolution at any chosen position, for the prediction of critical ocean states that require the shutdown of rig operations. We illustrate this using a real-world simulation of the Gulf of Mexico.

    2000-10-01

    The objective of the research described in this report was to provide data and insights that will enable the natural gas industry to (1) significantly improve the assessment of subsurface glycol-related contamination at sites where it is known or suspected to have occurred and (2) make scientifically valid decisions concerning the management and/or remediation of that contamination. The described research was focused on subsurface transport and fate issues related to triethylene glycol (TEG), diethylene glycol (DEG), and ethylene glycol (EG). TEG and DEG were selected for examination because they are used in a vast majority of gas dehydration units, and EG was chosen because it is currently under regulatory scrutiny as a drinking water pollutant. Because benzene, toluene, ethylbenzene, and xylenes (collectively referred to as BTEX) compounds are often very closely associated with glycols used in dehydration processes, the research necessarily included assessing cocontaminant effects on waste mobility and biodegradation. BTEX hydrocarbons are relatively water-soluble and, because of their toxicity, are of regulatory concern. Although numerous studies have investigated the fate of BTEX, and significant evidence exists to indicate the potential biodegradability of BTEX in both aerobic and anaerobic environments (Kazumi and others, 1997; Krumholz and others, 1996; Lovely and others, 1995; Gibson and Subramanian, 1984), relatively few investigations have convincingly demonstrated in situ biodegradation of these hydrocarbons (Gieg and others, 1999), and less work has been done on investigating the fate of BTEX species in combination with miscible glycols. To achieve the research objectives, laboratory studies were conducted to (1) characterize glycol related dehydration wastes, with emphasis on identification and quantitation of coconstituent organics associated with TEG and EG wastes obtained from dehydration units located in the United States and Canada, (2) evaluate

    In order to enhance the capability of petroleum exploration and development techniques, three year project (1994 - 1997) was initiated on the research of direct hydrocarbon exploration and gas reservoir development. This project consists of four sub-projects. (1) Oil(Gas) - source rock correlation technique: The overview of bio-marker parameters which are applicable to hydrocarbon exploration has been illustrated. Experimental analysis of saturated hydrocarbon and bio-markers of the Pohang E and F core samples has been carried out. (2) Study on surface geochemistry and microbiology for hydrocarbon exploration: the test results of the experimental device for extraction of dissolved gases from water show that the device can be utilized for the gas geochemistry of water. (3) Development of gas and gas condensate reservoirs: There are two types of reservoir characterization. For the reservoir formation characterization, calculation of conditional simulation was compared with that of unconditional simulation. In the reservoir fluid characterization, phase behavior calculations revealed that the component grouping is more important than the increase of number of components. (4) Numerical modeling of seismic wave propagation and full waveform inversion: Three individual sections are presented. The first one is devoted to the inversion theory in general sense. The second and the third sections deal with the frequency domain pseudo waveform inversion of seismic reflection data and refraction data respectively. (author). 180 refs., 91 figs., 60 tabs.

  12. Program options to explore ocean worlds

    Including Earth, roughly a dozen water ocean worlds exist in the solar system: the relict worlds Ceres and Mars, vast oceans inside most of the large Jovian and Saturnian icy moons, and Kuiper Belt Objects like Triton, Charon, and Pluto whose geologies are dominated by water and ammonia. Key pieces of the ocean-world science puzzle - which when completed may reveal whether life is widespread in the cosmos, why it exists where it does, and how it originates - are distributed among them. The eventual exploration of all these worlds will yield humanity's total tangible knowledge about life in the universe, essentially forever. Thus, their exploration has existential significance for humanity's self-regard, and indeed perhaps of our place in the natural scheme. The matter of planning how to pursue such a difficult and unprecedented exploration opportunity is therefore historic. The technical challenges are formidable, far harder than at Mars: missions to the Jovian and Saturnian ocean worlds are severely power-limited; trip times can be as much as a half decade and decade, respectively. And the science targets are global-scale oceans beneath kilometers of cryogenic ice. Reaching and exploring them would be a multi-generational undertaking, so again it is essential to plan and prepare. Today, we lack the instrumentation, subsystems, and remote operational-intelligence technologies needed to build and use exploration avatars as good as what we can envision needing. Each ocean world holds a piece of the puzzle, but the three priority targets are Europa at Jupiter, and Enceladus and Titan at Saturn. As with the systematic exploration of Mars, exploring these diverse worlds poses a complex technical and programmatic challenge - a strategic challenge - that needs to be designed and managed if each generation is to see its work bear fruit, and if the space science community is to make most effective use of the public money devoted to the quest. Strategic programs benefit from

    During the first part of the next century, the United States will return to the Moon to create a permanent lunar base, and, before the year 2019, we will send a human mission to Mars. In addition to these human operations, the Space Exploration Initiative will integrally incorporate robotic lunar and Mars missions. In achieving these efforts to expand human presence and activity in space and also exerted and frontiers of human knowledge, the SEI will require an array of new technologies. Mission architecture definition is still underway, but previous studies indicate that the SEI will require developments in areas such as advanced engines for space transportation, in-space assembly and construction to support permanent basing of exploration systems in space, and advanced surface operations capabilities including adequate levels of power and surface roving vehicles, and technologies to support safely long-duration human operations in space. Plans are now being put into place to implement an Exploration Technology Program (ETP) which will develop the major technologies needed for SEI. In close coordination with other ongoing U.S. government research and development efforts, the ETP will provide in the near term clear demonstrations of potential exploration technologies, research results to support SEI architecture decisions, and a foundation of mature technology that is ready to be applied in the first round of SEI missions. In addition to the technology needed for the first round of SEI missions, the ETP will also put in place a foundation of research for longer-term technology needs—ultimately leading the human missions to Mars. The Space Exploration Initiative and the Exploration Technology Program will challenge the best and the brightest minds across government, industry and academia, inspiring students of all ages and making possible future terrestial applications of SEI technologies that may create whole new industries for the future.

    This paper described a method for analyzing the efficiency of exploration investment, which can improve corporate planning. Exploration expenditure is held to be a main indicator of economic activities in the oil and gas industry because exploration is supposed to lead to booking more reserves and increased production. A model was developed for analyzing the correlation between exploration expenditure and producer's reserves and production for conventional and unconventional gas plays in the United States. The model was used to quantitatively assess the exploration expenditures production and reserves of different producers for various conventional and unconventional gas plays. Producer's booked reserves, production from public sources, and reserves and production forecasts were incorporated into the model, which was used to analyze different types of exploration expenditure (land, drilling, and seismic) incurred at various times prior to reserves and production being booked. There was an overall positive correlation between exploration expenditure and reserves and production, but there was significant variance in the correlation between various producers operating in different plays. Unproved land acquisition was strongly correlated to the booking of proved reserves, but there was no correlation between unproved land acquisition and exploration expenditure ratio, reserves, or production. A number of companies had a high exploration expenditure to overall expenditure ratio, but the resulting payoffs were inconsistent. 6 refs., 1 tab., 6 figs.

    The sector transports it is the biggest plaintiff of final energy and the biggest atmospheric pollutant. The above-mentioned has wakened up a particular interest in the national government, especially in the UPME, for the analysis of its problem, because it is wanted to contribute solutions to rationalize the consumption, to increase the energy efficiency, to reduce the environmental contamination, to diversify the offer of fuels and to strengthen the commercial scale by means of the decrease of the energy import, finally, to improve the life quality and to impel the sustainable development. In it offers of that objective, it was studied the situation of the sector detailed and starting from there a strategy of clean and efficient mobility will be determined in that the efforts of Mines and Energy, Environment and Transport Ministries. In this respect, many countries of the world have begun investigation programs and development with those that it is looked for to optimize the car fuels re-formulation and to implant new motors technologies. Their purpose is to have technological solutions that reduce the contamination for vehicles. In particular the design of motors for gassy fuels, has given excellent results, because it allows to take advantage of the maximum the characteristics of those fuels, with what bigger yields, bigger power, smaller contamination and bigger autonomy are obtained

    Whether exploring in the Empty Quarter, drilling offshore in the Gulf of Mexico, or monitoring gas pipelines or oil wells in the deserts, communications is a key element to the success of oil and gas operations. Secure, efficient communications is required between remote, isolated locations and head offices to report on work status, dispatch supplies and repairs, report on-site emergencies, transfer geophysical surveys and real-time drilling data. Drilling and exploration firms have traditionally used land-based terrestrial networks that rely on radio transmissions for voice and data communications to offshore platforms and remote deep desert drilling rigs. But these systems are inefficient and have proven inflexible with today's drilling and exploration communications demands, which include high-speed data access, telephone and video conferencing. In response, numerous oil and gas exploration entities working in deep waters and remote deep deserts have all tapped into what is an ideal solution for these needs: Very Small Aperture Terminal Systems (VSAT) for broadband access services. This led to the use of Satellite Communication Systems for a wide range of applications that were difficult to achieve in the past, such as real-time applications transmission of drilling data and seismic information. This paper provides a thorough analysis of opportunities for satellite technology solutions in support of oil and gas operations. Technologies, architecture, service, networking and application developments are discussed based upon real field experience. More specifically, the report addresses: VSAT Opportunities for the Oil and Gas Operations, Corporate Satellite Business Model Findings, Satellite Market Forecasts

    The implementation of national and regional programs for the development of new oil and gas provinces of Eastern Siberia poses the challenge of increasing geological exploration. The current drilling service companies' market structure, as well as the strategic task of search and exploration effectiveness requires qualitatively new approaches for choosing a contractor. The proposed strategy to select a contractor based on comprehensive analysis of certain groups of industrial, financial, infrastructural criteria allows not only to optimize the costs of exploration activities, but also to minimize preventively the risks of a poor geological exploration. The authors' SWOT- analysis of the marketing strategy of ''Gazprom neft'' for choosing a contractor outlined the problem of imperfection of the Russian legislation in the sphere of activities of service companies in the oil and gas sector

    The National Gas Hydrate Program Expedition 02 (NGHP-02) was conducted from 3-March-2015 to 28-July-2015 off the eastern coast of India. The primary objective of this expedition was the exploration and discovery of highly saturated gas hydrate occurrences in sand reservoirs that would be targets of future production testing. The first 2 months of the expedition were dedicated to logging while drilling (LWD) operations with a total of 25 holes being drilled and logged. The next 3 months were dedicated to coring operations at 10 of the most promising sites. NGHP-02 downhole logging, coring and formation pressure testing have confirmed the presence of large, highly saturated, gas hydrate accumulations in coarse-grained sand-rich depositional systems throughout the Krishna-Godavari Basin within the regions defined during NGHP-02 as Area-B, Area-C, and Area-E. The nature of the discovered gas hydrate occurrences closely matched pre-drill predictions, confirming the project developed depositional models for the sand-rich depositional facies in the Krishna-Godavari and Mahanadi Basins. The existence of a fully developed gas hydrate petroleum system was established in Area-C of the Krishna-Godavari Basin with the discovery of a large slope-basin interconnected depositional system, including a sand-rich, gas-hydrate-bearing channel-levee prospect at Sites NGHP-02-08 and -09. The acquisition of closely spaced LWD and core holes in the Area-B L1 Block gas hydrate accumulation have provided one of the most complete three-dimensional petrophysical-based views of any known gas hydrate reservoir system in the world. It was concluded that Area-B and Area-C in the area of the greater Krishna-Godavari Basin contain important world-class gas hydrate accumulations and represent ideal sites for consideration of future gas hydrate production testing.

    Shale gas operations may affect the quality of air, water and landscapes; furthermore, it can induce seismic activity, with the possible impacts on the surrounding infrastructure. The SHEER project aims at setting up a probabilistic methodology to assess and mitigate the short and the long term environmental risks connected to the exploration and exploitation of shale gas. In particular we are investigating risks associated with groundwater contamination, air pollution and induced seismicity. A shale gas test site located in Poland (Wysin) has been monitored before, during and after the fracking operations with the aim of assessing environmental risks connected with groundwater contamination, air pollution and earthquakes induced by fracking and injection of waste water. The severity of each of these hazards depends strongly on the unexpected enhanced permeability pattern, which may develop as an unwanted by-product of the fracking processes and may become pathway for gas and fluid migration towards underground water reservoirs or the surface. The project is devoted to monitor and understand how far this enhanced permeability pattern develops both in space and time. The considered hazards may be at least partially inter-related as they all depend on this enhanced permeability pattern. Therefore they are being approached from a multi-hazard, multi parameter perspective. We expect to develop methodologies and procedures to track and model fracture evolution around shale gas exploitation sites and a robust statistically based, multi-parameter methodology to assess environmental impacts and risks across the operational lifecycle of shale gas. The developed methodologies are going to be applied and tested on a comprehensive database consisting of seismicity, changes of the quality of ground-waters and air, ground deformations, and operational data collected from the ongoing monitoring episode (Wysin) and past episodes: Lubocino (Poland), Preese Hall (UK), Oklahoma (USA

    Most modelling studies that explore emission mitigation scenarios only look into least-cost emission pathways, induced by a carbon tax. This means that European policies targeting specific – sometimes relatively costly – technologies, such as electric cars and advanced insulation measures, are usually not evaluated as part of cost-optimal scenarios. This study explores an emission mitigation scenario for Europe up to 2050, taking as a starting point specific emission reduction options instead of a carbon tax. The purpose is to identify the potential of each of these policies and identify trade-offs between sectoral policies in achieving emission reduction targets. The reduction options evaluated in this paper together lead to a reduction of 65% of 1990 CO 2 -equivalent emissions by 2050. More bottom-up modelling exercises, like the one presented here, provide a promising starting point to evaluate policy options that are currently considered by policy makers. - Highlights: ► We model the effects of 15 climate change mitigation measures in Europe. ► We assess the greenhouse gas emission reduction potential in different sectors. ► The measures could reduce greenhouse gas emissions by 60% below 1990 levels in 2050. ► The approach allows to explore arguably more relevant climate policy scenarios

    The National Gas Hydrate Program Expedition 01 (NGHP-01) targeted gas hydrate accumulations offshore of the Indian Peninsula and along the Andaman convergent margin. The primary objectives of coring were to understand the geologic and geochemical controls on the accumulation of methane hydrate and their linkages to underlying petroleum systems. Four areas were investigated: 1) the Kerala-Konkan Basin in the eastern Arabian Sea, 2) the Mahanadi and 3) Krishna-Godavari Basins in the western Bay of Bengal, and 4) the Andaman forearc Basin in the Andaman Sea.Upward flux of methane at three of the four of the sites cored during NGHP-01 is apparent from the presence of seafloor mounds, seismic evidence for upward gas migration, shallow sub-seafloor geochemical evidence of methane oxidation, and near-seafloor gas composition that resembles gas from depth.The Kerala-Konkan Basin well contained only CO2 with no detectable hydrocarbons suggesting there is no gas hydrate system here. Gas and gas hydrate from the Krishna-Godavari Basin is mainly microbial methane with δ13C values ranging from −58.9 to −78.9‰, with small contributions from microbial ethane (−52.1‰) and CO2. Gas from the Mahanadi Basin was mainly methane with lower concentrations of C2-C5 hydrocarbons (C1/C2 ratios typically >1000) and CO2. Carbon isotopic compositions that ranged from −70.7 to −86.6‰ for methane and −62.9 to −63.7‰ for ethane are consistent with a microbial gas source; however deeper cores contained higher molecular weight hydrocarbon gases suggesting a small contribution from a thermogenic gas source. Gas composition in the Andaman Basin was mainly methane with lower concentrations of ethane to isopentane and CO2, C1/C2 ratios were mainly >1000 although deeper samples were exploration and occurs in a forearc basin. Each of these hydrate-bearing systems overlies and is likely supported by the presence and possible migration of gas from deeper gas-prone petroleum

    Exploration in the Sonai Plain by Sekyu Shigen Kaihatsu Kabushiki Kaisha (Oil Resources Development Corporation) since 1955 is described. The development tasks are made difficult due to the presence of permeability traps. However, 41 out of 65 wells drilled up to late March of 1965 have been successful. Quantities of crude oil and natural gas produced in 1963 were, respectively, 5 and 6 times those of 1958. The Sonai Plain is a relatively new area, and there are still many unknown factors, yet the rate of development has increased greatly. More and deeper wells are expected to be drilled with even better results.

    Full Text Available Pair programming is a collaborative programming practice that places participants in dyads, working in tandem at one computer to complete programming assignments. Pair programming studies with Computer Science (CS and Software Engineering (SE majors have identified benefits such as technical productivity, program/design quality, academic performance, and increased satisfaction for their participants. In this paper, pair programming is studied with Management Information Systems (MIS majors, who (unlike CS and SE majors taking several programming courses typically take only one programming course and often struggle to develop advanced programming skills within that single course. The researchers conducted two pair programming experiments in an introductory software development course for MIS majors over three semesters to determine if pair programming could enhance learning for MIS students. The program results, researchers’ direct observations, and participants’ responses to a survey questionnaire were analyzed after each experiment. The results indicate that pair programming appears to be beneficial to MIS students’ technical productivity and program design quality, specifically the ability to create programs using high-level concepts. Additionally, results confirmed increased student satisfaction and reduced frustration, as the pairs worked collaboratively to produce a program while actively communicating and enjoying the process.

    Prepared by the Alberta Human Resources and Employment, this report provides a summary of the lost-time injuries and disease descriptions of workers injured while employed in the upstream oil and gas industries in Alberta during the period 1995 to 1999. The report includes the characteristics of the injured worker and the risk of injury to workers in the industries in Alberta, as well as the cost of injuries and revenue by means of total premiums paid by the employers. The occupational fatalities that were accepted by the Workers Compensation Board and investigated by the Occupational Health and Safety were summarized in the report along with a brief description of the injuries. The aim was to provide information concerning health and safety issues to government, employers, workers, and health and safety officers in the industries in Alberta about health and safety issues. The focus was placed on the oil and gas exploration and development sub-sector. Defined as all upstream oil field activities of employers which generate revenue from the production and sale of crude oil and/or natural gas, the sub-sector comprises major integrated oil and gas companies and small independent producers. In those cases where the owner/producer operates its own upstream production/processing facilities, they form an integral part of this sub-section. In addition, oil and gas marketing firms are included. Oil/gas well, well head equipment; flow lines/gathering systems tied into field processing facilities; battery sites/compressors stations; crude oil separators and natural gas dehydrators/treaters; natural gas/sulfur processing plants; heavy oil projects including steam generation; and other enhanced recovery methods are all included in the sub-sector. The other sub-sectors in the upstream oil and gas industries are: exploration, oilfield maintenance and construction, well servicing with service rigs and power swivels, drilling of oil and gas wells, oilfield downhole and other

    Lower-cost approaches to drilling and reservoir utilization are made possible by adapting both emerging and new technology to the unique, low risk NGH natural gas resource. We have focused on drilling, wellbore lining technology, and reservoir management with an emphasis on long-term sand control and adaptive mechanical stability during NGH conversion to its constituent gas and water. In addition, we suggest that there are opportunities for management of both the gas and water with respect to maintaining desired thermal conditions. Some of the unique aspects of NGH deposits allow for new, more efficient technology to be applied to development, particularly in drilling. While NGH-bearing sands are in deepwater, they are confined to depths beneath the seafloor of 1.2 kilometers or less. As a result, they will not be significantly above hydrostatic pressure, and temperatures will be less than 30 oC. Drilling will be through semi-consolidated sediment without liquid hydrocarbons. These characteristics mean that high capability drillships are not needed. What is needed is a new perspective about drilling and producing NGH. Drilling from the seafloor will resolve the high-pressure differential between a wellhead on the sea surface in a vessel and reservoir to about the hydrostatic pressure difference between the seafloor and, at most, the base of the GHSZ. Although NGH production will begin using "off-the-shelf" technology, innovation will lead to new technology that will bring down costs and increase efficiency in the same way that led to the shale breakthrough. Commercial success is possible if consideration is given to what is actually needed to produce NGH in a safe and environmentally manner. Max, M.D. 2017. Wellbore Lining for Natural Gas Hydrate.

    A review is given of some of the most significant new developments that have occurred during the past three years in the area of nuclear techniques applied to the exploration for and production of oil and gas deposits. Experimental and theoretical studies have been carried out aimed at improving pulsed neutron logging tools and upgrading interpretation of data from such tools. Pulsed neutron borehole generators and gamma-ray spectroscopy have been combined in carbon/oxygen logging to provide a means of determining formation oil saturation in cased holes that is independent of water salinity. Use of pulsed neutron logs in the log-inject-log technique has been tested and evaluated in several field studies. The combination of a gamma-gamma density log and a borehole gravimeter has been used to detect economically important gas accumulations at distances from a borehole that are well beyond the depth of investigation of conventional logging techniques. The depths of investigation of several commercial nuclear logging tools have been studied in laboratory investigations. Possible geological applications of natural gamma-ray spectral logs have been investigated through the study of large sample suites and in specific field applications. The extensive use of digital recording of logging data and well-site analysis by minicomputer are expected to have a significant influence on future logging programmes and logging sonde designs. The present status of stable isotope geochemistry and radioactive tracer surveys is reviewed. (author)

    Bottom Simulating Reflectors (BSRs), which have been considered as one of major indicators of the gas hydrate in sub-seafloor, have been detected and widely distributed in offshore SW Taiwan. The Central Geological Survey of Taiwan launched a 4-year multidisciplinary gas hydrate investigation program in 2004 to explore the potential of gas hydrate resources in the area. The results indicate that enormous amounts of gas hydrate should occur beneath the seafloor, although none of solid gas hydrate samples have been found. Therefore, a second stage of another 4-year program started in 2008 to extend the studies/investigation. In the ongoing projects, some specific areas will be studied in detail to assess the components of gas hydrate petroleum system and provide a better assessment of the energy resource potential of gas hydrate in the target area. In addition to the field investigations, phase equilibrium of gas hydrate via experiment, theoretical modeling, and molecular simulations has also been studied. The results can provide insights into gas hydrate production technology. Considering the high potential energy resources, the committee of the energy national science and technology program suggests initiating a master project to plan the strategy and timeline for the gas hydrate exploration, exploitation and production in Taiwan. The plan will be introduced in this presentation.

    This is the second technical report, covering the period from April 1, 2003 through September 30, 2003. This project brings together three parts of the oil exploration, development, and permitting process to form the foundation for a more fully integrated information technology infrastructure for the State of Alaska. The geo-technical component is a shared effort between the State Department of Administration and the US Department of Energy. The Alaska Oil and Gas Conservation Commission is rapidly converting high volumes of paper documents and geo-technical information to formats suitable for search and retrieval over the Internet. The permitting component is under the lead of the DNR Office of Project Management and Permitting. A web-based system will enable the public and other review participants to track permit status, submit and view comments, and obtain important project information on-line. By automating several functions of the current manual process, permit applications will be completed more quickly and accurately, and agencies will be able to complete reviews with fewer delays. Structural changes are taking place in terms of organization, statutory authority, and regulatory requirements. Geographic Information Systems are a central component to the organization of information, and the delivery of on-line services. Progress has been made to deploy the foundation system for the shared GIS based on open GIS protocols to the extent feasible. Alaska has nearly one-quarter of the nation's supply of crude oil, at least five billion barrels of proven reserves. The American Association of Petroleum Geologists report that the 1995 National Assessment identified the North Slope as having 7.4 billion barrels of technically recoverable oil and over 63 trillion cubic feet of natural gas. From these reserves, Alaska produces roughly one-fifth of the nation's daily crude oil production, or approximately one million barrels per day from over 1,800 active wells.

    The Gas Research Institute (GRI) is a private not-for-profit membership organization of natural gas pipelines, distribution companies and natural gas producers. GRI's purpose is to plan, to manage and to develop financing for a gas-related research and development (R and D) program on behalf of its members and their customers. GRI does not do any research itself. GRI's R and D program is designed to provide advanced technologies for natural gas supply, transport, storage, distribution and end-use applications in all markets. In addition, basic research is conducted for GRI in these areas to build a foundation for future technology breakthroughs. Work in the Environment and Safety Research Department includes sections interested in: supply related research, air quality research, end use equipment safety research, gas operations safety research, and gas operations environmental research. The Natural Gas Supply Program has research ongoing in such areas as: restoration of pipeline right-of-ways; cleaning up town gas manufacturing sites; the development of methanogenic bacteria for soil and groundwater cleanup; development of biological fluidized carbon units for rapid destruction of carbonaceous compounds; research on liquid redox sulfur recovery for sulfur removal from natural gas; research on produced water and production wastes generated by the natural gas industry; environmental effects of coalbed methane production; and subsurface effects of natural gas operations. The western coalbed methane and ground water programs are described

    Gas hydrates bearing layer can be normally identified by a basement simulating reflector (BSR) or well logging because of their high acoustic- and electric impedance compared to the surrounding formation. These characteristics of the gas hydrate can also represent contrast of in-situ formation strength. We here attempt to describe gas hydrate bearing layers based on the equivalent strength (EST). The Indian National Gas Hydrate Program (NGHP) Expedition 02 was executed 2015 off the eastern margin of the Indian Peninsula to investigate distribution and occurrence of gas hydrates. From 25 drill sites, downhole logging data, cored samples, and drilling performance data were collected. Recorded drilling performance data was converted to the EST, which is a developed mechanical strength calculated only by drilling parameters (top drive torque, rotation per minute , rate of penetration , and drill bit diameter). At a representative site, site 23, the EST shows constant trend of 5 to 10 MPa, with some positive peaks at 0 - 270 mbsf interval, and sudden increase up to 50 MPa above BSR depth (270 - 290 mbsf). Below the BSR, the EST stays at 5-10 MPa down to the bottom of the hole (378 mbsf). Comparison of the EST with logging data and core sample description suggests that the depth profiles of the EST reflect formation lithology and gas hydrate content: the EST increase in the sand-rich layer and the gas hydrate bearing zone. Especially in the gas hydrate zone, the EST curve indicates approximately the same trend with that of P-wave velocity and resistivity measured by downhole logging. Cross plot of the increment of the EST and resistivity revealed the relation between them is roughly logarithmic, indicating the increase and decrease of the EST strongly depend on the saturation factor of gas hydrate. These results suggest that the EST, proxy of in-situ formation strength, can be an indicator of existence and amount of the gas-hydrate layer. Although the EST was calculated

    Graphic processing Units (GPUs) are gaining ground in high-performance computing. CUDA (an extension to C) is most widely used parallel programming framework for general purpose GPU computations. However, the task of writing optimized CUDA program is complex even for experts. We present a method for restructuring loops into an optimized CUDA kernels based on a 3-step algorithm which are loop tiling, coalesced memory access, and resource optimization. We also establish the relationships between the influencing parameters and propose a method for finding possible tiling solutions with coalesced memory access that best meets the identified constraints. We also present a simplified algorithm for restructuring loops and rewrite them as an efficient CUDA Kernel. The execution model of synthesized kernel consists of uniformly distributing the kernel threads to keep all cores busy while transferring a tailored data locality which is accessed using coalesced pattern to amortize the long latency of the secondary memory. In the evaluation, we implement some simple applications using the proposed restructuring strategy and evaluate the performance in terms of execution time and GPU throughput. © 2012 IEEE.

    2003-08-04

    The objective of this project is to eliminate three closely inter-related barriers to oil production in Alaska through the use of a geographic information system (GIS) and other information technology strategies. These barriers involve identification of oil development potential from existing wells, planning projects to efficiently avoid conflicts with other interests, and gaining state approvals for exploration and development projects. Each barrier is the result of either current labor-intensive methods or poorly accessible information. This project brings together three parts of the oil exploration, development, and permitting process to form the foundation for a more fully integrated information technology infrastructure for the State of Alaska. This web-based system will enable the public and other review participants to track permit status, submit and view comments, and obtain important project information online. By automating several functions of the current manual process, permit applications will be completed more quickly and accurately, and agencies will be able to complete reviews with fewer delays. The application will include an on-line diagnostic Coastal Project Questionnaire to determine the suite of permits required for a specific project. The application will also automatically create distribution lists based on the location and type of project, populate document templates for project review start-ups, public notices and findings, allow submission of e-comments, and post project status information on the Internet. Alaska has nearly one-quarter of the nation's supply of crude oil, at least five billion barrels of proven reserves. The American Association of Petroleum Geologists report that the 1995 National Assessment identified the North Slope as having 7.4 billion barrels of technically recoverable oil and over 63 trillion cubic feet of natural gas. From these reserves, Alaska produces roughly one-fifth of the nation's daily crude oil

    Breaking the monopoly of PETROBRAS for the activities of exploration and production of oil and natural gas has occurred in Brazil in 1995 by the Constitutional Amendment No 9 followed by the promulgation of the Law 9.478 of 1997, the 'Law of Oil' and the creation of the Agencia Nacional do Petroleo - ANP, with powers to regulate, recruit and monitor the oil and natural gas industry. The new regulatory framework has established the award granted by the State, through bids organized by the ANP, of the oil and gas exploration and production activities. This new model has established that the offers to purchase blocks must be composed by the Signature Bonus, Minimum Exploration Program and percentages of Local Content for the stages of exploration and development of production. As a result of market opening and the completion of bids over these 10 years, there has been a significant expansion of investment in the industry, revealing that the demands of Local Content rightly acted as a strong mechanism inducing the participation of local industry supplier of goods and services. In practical terms, in 1997 the participation of the sector of oil and gas in the Brazilian GDP was approximately 2.5% and now comes to 10.5%, or each R$ 100.00 generated in the country, R$ 10.50 come from the sector of oil and gas.

    Full Text Available In the past five years, shale gas exploration and development has grown in a leaping-forward way in China. Following USA and Canada, China is now the third country where industrial shale gas production is realized, with the cumulative production exceeding 60 × 108 m3 until the end of 2015. In this paper, the main achievements of shale gas exploration and development in China in recent years were reviewed and the future development prospect was analyzed. It is pointed out that shale gas exploration and development in China is, on the whole, still at its early stage. Especially, marine shale gas in the Sichuan Basin has dominated the recent exploration and development. For the realization of shale gas scale development in China, one key point lies in the breakthrough and industrial production of transitional facies and continental facies shale gas. Low–moderate yield of shale gas wells is the normal in China, so it is crucial to develop key exploration and development technologies. Especially, strictly controlling single well investment and significantly reducing cost are the important means to increase shale gas exploration and development benefits. And finally, suggestions were proposed in five aspects. First, continuously strengthen theoretical and technical researches, actively carry out appraisal on shale gas “sweet spots”, and gradually accumulate development basis. Second, stress on primary evaluation of exploration and development, highlight the effective implementation of shale gas resources, and control the rhythm of appraisal drilling and productivity construction. Third, highlight fine description and evaluation of shale gas reservoirs and increase the overall development level. Fourth, intensify the research on exploration and development technologies in order to stand out simple and practical technologies with low costs. And fifth, summarize the experiences in fast growth of shale gas exploration and development, highlight

    Explorer was the original American space program and Explorer 1 its first satellite, launched in 1958. Sixty years later, it is the longest continuously running space program in the world, demonstrating to the world how we can explore the cosmos with small spacecraft. Almost a hundred Explorers have already been launched.  Explorers have made some of the fundamental discoveries of the Space Age.Explorer 1 discovered Earth’s radiation belts. Later Explorers surveyed the Sun, the X-ray and ultraviolet universes, black holes, magnetars and gamma ray bursts. An Explorer found the remnant of the Big Bang. One Explorer chased and was the first to intercept a comet. The program went through a period of few launches during the crisis of funding for space science in the 1980s. However, with the era of ‘faster, cheaper, better,’ the program was reinvented, and new exiting missions began to take shape, like Swift and the asteroid hunter WISE.  Discovering the Cosmos with Small Spacecraft gives an account of ...

    Shale gas exploration in China started late but is progressing very quickly with the strong support from Central Government. China has 21.8 tcm technically recoverable shale gas resources and 764.3 bcm proved shale gas reserve, mainly in marine facies in Sichuan basin. In 2016, overall shale gas production in China is around 7.9 bcm, while it is set to reach 10 bcm in 2017 and 30 bcm in 2020. BP is the only remaining IOC actor in shale gas exploration in China partnering with CNPC in 2 blocks in Sichuan basin. China is encouraging shale gas business both at Central level and at Provincial level through establishing development plan, continuation of subsidies and research funding. Engineering services for shale gas development and infrastructures are developing, while the overall cost and gas marketing conditions will be key factors for the success in shale gas industry.

    The development of shale gas in the United Kingdom (UK) using hydraulic fracturing, more commonly known as ‘fracking’, remains in its infancy. Yet understanding public attitudes for this fledgling industry is important for future policy considerations, decision-making and for industry stakeholders. This study uses data collected from the University of Nottingham, UK nationwide online survey (n=3823) conducted in September 2014, to consider ten hypothesises about the UK public's attitudes towards shale gas. From the survey data we can see that 43.11% of respondents support shale gas extraction in the UK. Furthermore, our results show that women, class DE respondents, non-Conservative party supporters, and respondents who positively associate shale gas with water contamination or earthquakes are less likely to support the extraction of shale gas in the UK. We also discuss potential policy implications for the UK government arising from these findings. - Highlights: • September 2014 survey of British attitudes towards allowing shale gas extraction. • Over 75% or respondents correctly identify shale gas. • 43.11% of respondents support shale gas extraction in the UK.

    In response to the growing importance of space exploration in future planning, the Committee on Space Research (COSPAR) Panel on Exploration (PEX) was chartered to provide independent scientific advice to support the development of exploration programs and to safeguard the potential scientific assets of solar system objects. In this report, PEX elaborates a stepwise approach to achieve a new level of space cooperation that can help develop world-wide capabilities in space science and exploration and support a transition that will lead to a global space exploration program. The proposed stepping stones are intended to transcend cross-cultural barriers, leading to the development of technical interfaces and shared legal frameworks and fostering coordination and cooperation on a broad front. Input for this report was drawn from expertise provided by COSPAR Associates within the international community and via the contacts they maintain in various scientific entities. The report provides a summary and synthesis of science roadmaps and recommendations for planetary exploration produced by many national and international working groups, aiming to encourage and exploit synergies among similar programs. While science and technology represent the core and, often, the drivers for space exploration, several other disciplines and their stakeholders (Earth science, space law, and others) should be more robustly interlinked and involved than they have been to date. The report argues that a shared vision is crucial to this linkage, and to providing a direction that enables new countries and stakeholders to join and engage in the overall space exploration effort. Building a basic space technology capacity within a wider range of countries, ensuring new actors in space act responsibly, and increasing public awareness and engagement are concrete steps that can provide a broader interest in space exploration, worldwide, and build a solid basis for program sustainability.

    Full Text Available The Sichuan Basin, a hotspot and one of the most successful areas for shale gas exploration and development, can largely reflect and have a big say in the future prospect of shale gas in China. Through an overall review on the progress in shale gas exploration and development in the Sichuan Basin, we obtained the following findings: (1 the Sichuan Basin has experienced the marine and terrestrial depositional evolution, resulting in the deposition of three types of organic-matter-rich shales (i.e. marine, transitional, and terrestrial, and the occurrence of six sets of favorable shale gas enrichment strata (i.e. the Sinian Doushantuo Fm, the Cambrian Qiongzhusi Fm, the Ordovician Wufeng–Silurian Longmaxi Fm, the Permian Longtan Fm, the Triassic Xujiahe Fm, and the Jurassic Zhiliujing Fm; (2 the five key elements for shale gas accumulation in the Wufeng-Longmaxi Fm are deep-water shelf facies, greater thickness of organic-rich shales, moderate thermal evolution, abundant structural fractures, reservoir overpressure; and (3 the exploration and development of shale gas in this basin still confronts two major challenges, namely, uncertain sweet spots and potential prospect of shale gas, and the immature technologies in the development of shale gas resources at a depth of more than 3500 m. In conclusion, shale gas has been discovered in the Jurassic, Triassic and Cambrian, and preliminary industrial-scale gas has been produced in the Ordovician-Silurian Fm in the Sichuan Basin, indicating a promising prospect there; commercial shale gas can be produced there with an estimated annual gas output of 30–60 billion m3; and shale gas exploration and production experiences in this basin will provide valuable theoretical and technical support for commercial shale gas development in China.

    2001-12-01

    NASA's newly restructured Mars Exploration Program (MEP) is finally on the way to Mars with the successful April 7 launch of the 2001 Mars Odyssey Orbiter. In addition, the announcement by the Bush Administration that the exploration of Mars will be a priority within NASA's Office of Space Science further cements the first decade of the new millennium as one of the major thrusts to understand the "new" Mars. Over the course of the past year and a half, an integrated team of managers, scientists, and engineers has crafted a revamped MEP to respond to the scientific as well as management and resource challenges associated with deep space exploration of the Red Planet. This article describes the new program from the perspective of its guiding philosophies, major events, and scientific strategy. It is intended to serve as a roadmap to the next 10-15 years of Mars exploration from the NASA viewpoint. [For further details, see the Mars Exploration Program web site (URL): http://mars.jpl.nasa.gov]. The new MEP will certainly evolve in response to discoveries, to successes, and potentially to setbacks as well. However, the design of the restructured strategy is attentive to risks, and a major attempt to instill resiliency in the program has been adopted. Mars beckons, and the next decade of exploration should provide the impetus for a follow-on decade in which multiple sample returns and other major program directions are executed. Ultimately the vision to consider the first human scientific expeditions to the Red Planet will be enabled. By the end of the first decade of this program, we may know where and how to look for the elusive clues associated with a possible martian biological record, if any was every preserved, even if only as "chemical fossils."

  9. Hydrogen-Enhanced Natural Gas Vehicle Program

    Hyde, Dan; Collier, Kirk

    2009-01-22

    The project objective is to demonstrate the viability of HCNG fuel (30 to 50% hydrogen by volume and the remainder natural gas) to reduce emissions from light-duty on-road vehicles with no loss in performance or efficiency. The City of Las Vegas has an interest in alternative fuels and already has an existing hydrogen refueling station. Collier Technologies Inc (CT) supplied the latest design retrofit kits capable of converting nine compressed natural gas (CNG) fueled, light-duty vehicles powered by the Ford 5.4L Triton engine. CT installed the kits on the first two vehicles in Las Vegas, trained personnel at the City of Las Vegas (the City) to perform the additional seven retrofits, and developed materials for allowing other entities to perform these retrofits as well. These vehicles were used in normal service by the City while driver impressions, reliability, fuel efficiency and emissions were documented for a minimum of one year after conversion. This project has shown the efficacy of operating vehicles originally designed to operate on compressed natural gas with HCNG fuel incorporating large quantities of exhaust gas recirculation (EGR). There were no safety issues experienced with these vehicles. The only maintenance issue in the project was some rough idling due to problems with the EGR valve and piping parts. Once the rough idling was corrected no further maintenance issues with these vehicles were experienced. Fuel economy data showed no significant changes after conversion even with the added power provided by the superchargers that were part of the conversions. Driver feedback for the conversions was very favorable. The additional power provided by the HCNG vehicles was greatly appreciated, especially in traffic. The drivability of the HCNG vehicles was considered to be superior by the drivers. Most of the converted vehicles showed zero oxides of nitrogen throughout the life of the project using the State of Nevada emissions station.

    As part of three ongoing research projects, the Gas Research Institute (GRI) is studying the natural gas industry's impacts on wetlands and how to manage operations so that impacts can be minimized or eliminated. The objective of the first project is to gain a better understanding of the causes and processes of wetland loss in the Louisiana deltaic plain and what role gas pipeline canals play in wetland loss. On the basis of information gathered from the first projects, management and mitigation implications for pipeline construction and maintenance will be evaluated. The objective of the second project is to assess the floral and faunal communities on existing rights-of-way (ROWs) that pass through numerous types of wetlands across the United States. The emphasis of the project is on pipelines that were installed within the past five years. The objective of the third project is to evaluate the administrative, jurisdictional, technical, and economic issues of wetland mitigation banking. This paper discusses these projects, their backgrounds, some of the results to date, and the deliverables

  11. Strategic Biodiversity Risk Assessment (SBRA) of the offshore oil and gas exploration and production (E and P) plans and programs in Brazil; Avaliacao estrategica do risco a biodiversidade (AERB) nos planos e programas de E e P offshore de petroleo e gas natural no Brasil

    This thesis proposes a methodological framework, called Strategic Biodiversity Risk Assessment (SBRA), within Strategic Environmental Assessment (SEA), as a way to efficiently incorporate the risks to biodiversity caused by accidental spills into the strategic levels of offshore oil and gas E and P decision-making process. Moreover, this approach can also indicate the exclusion (or postponement) of bidding areas with extreme environmental sensitivity, as well as the choices for environmental-friendly E and P technologies. In order to exemplify this methodological framework application, two case studies are presented, one of the offshore O and G development program in southern Bahia state, Northeast of Brazil, and other of the offshore development plan in Abrolhos region, Brazil.

    1990-01-01

    This paper reports that although production and drilling declined in Virginia in 1989, there were interesting projects that should impact Virginal's future oil and gas potential. In Dickenson County, Equitable Resources (EREX) began development on two areas of coalbed methane and extended the limits of the Nora Coalbed Methane Field with an exploratory well. In Westmoreland County, Texaco drilled a deep test well in the Taylorsville Basin. While a depressed market caused a decline in natural gas production of four percent, there was significant new production from ten coalbed methane wells in Dickenson County. The coalbed methane wells produced 181,526 Mcf or over one percent of the total production in the state. The 1989 total of 17,935,376 Mcf produced from 752 wells was a four percent decline from the 1988 figure of 18,682,350 Mcf from 728 wells

    1997-03-01

    The US Department of Energy (DOE) and the California Energy Commission (CEC) held a program planning workshop on March 4--5, 1997 in Sacramento, California on the subject of a flexible, midsize gas turbine (FMGT). The workshop was also co-sponsored by the Electric Power Research Institute (EPRI), the Gas Research Institute (GRI), the Gas Turbine Association (GTA), and the Collaborative Advanced Gas Turbine Program (CAGT). The purpose of the workshop was to bring together a broad cross section of knowledgeable people to discuss the potential benefits, markets, technical attributes, development costs, and development funding approaches associated with making this new technology available in the commercial marketplace. The participants in the workshop included representatives from the sponsoring organizations, electric utilities, gas utilities, independent power producers, gas turbine manufacturers, gas turbine packagers, and consultants knowledgeable in the power generation field. Thirteen presentations were given on the technical and commercial aspects of the subject, followed by informal breakout sessions that dealt with sets of questions on markets, technology requirements, funding sources and cost sharing, and links to other programs.

  18. Project Icarus: Stakeholder Scenarios for an Interstellar Exploration Program

    Science.gov (United States)

    Hein, A. M.; Tziolas, A. C.; Osborne, R.

    The Project Icarus Study Group's objective is to design a mainly fusion-propelled interstellar probe. The starting point are the results of the Daedalus study, which was conducted by the British Interplanetary Society during the 1970's. As the Daedalus study already indicated, interstellar probes will be the result of a large scale, decade-long development program. To sustain a program over such long periods, the commitment of key stakeholders is vital. Although previous publications identified political and societal preconditions to an interstellar exploration program, there is a lack of more specific scientific and political stakeholder scenarios. This paper develops stakeholder scenarios which allow for a more detailed sustainability assessment of future programs. For this purpose, key stakeholder groups and their needs are identified and scientific and political scenarios derived. Political scenarios are based on patterns of past space programs but unprecedented scenarios are considered as well. Although it is very difficult to sustain an interstellar exploration program, there are scenarios in which this seems to be possible, e.g. the discovery of life within the solar system and on an exoplanet, a global technology development program, and dual-use of technologies for defence and security purposes. This is a submission of the Project Icarus Study Group.

    2014-10-01

    Full Text Available A steady high yield natural gas flow was tapped in the Ordovician strata of Well Gucheng 6 drilled in the Gucheng lower uplift in the Tarim Basin in 2012, marking the discovery of another carbonate gas exploration field after the other two fields in the middle and northern Tarim Basin (the so called Tazhong and Tabei in the industry. The exploration in the Gucheng lower uplift has experienced three stages: the first stage, marine facies clastic exploration from 1995 to 2003, focusing on the Devonian Donghe sandstone lithologic traps, the Silurian overlapping lithologic traps, and the Upper Ordovician shelf slope turbidites; the second stage focusing on the reef shoal carbonate reservoirs from 2003 to 2006, during which oil and gas were first discovered in Well Gucheng 4; the third stage can be divided into two periods, in the first period, deeper insight into interbed karstification reservoir exploration, intense research on tricky seismic issues, selection of favorable zones, and 3D seismic deployment in advance laid a robust foundation for breakthroughs in oil and gas exploration; and during 2009–2012, through an in-depth investigation, Well Gucheng 6 was drilled, bringing about the major breakthrough in oil and gas exploration in this study area. This success proves that the Lower Paleozoic carbonate rocks in the Gucheng area have good geological conditions and broad prospect for oil and gas exploration, which give us enlightenment in three aspects: a. new insight into geologic understanding is the prerequisite of exploration breakthrough; b. addressing bottleneck technologies, and acquiring 3D seismic data are the guarantees of exploration breakthrough; and c. emancipation of mind and persistent exploration are key to the findings in new domains.

  2. Modern Shale Gas Horizontal Drilling: Review of Best Practices for Exploration Phase Planning and Execution

    Institute of Scientific and Technical Information of China (English)

    Nathaniel Harding; Stephen Smith; John Shelton; Mike D. Bumaman

    2009-01-01

    The challenging characteristics of shale formations often require horizontal drilling to economically develop their potential. While every shale gas play is unique, there are several best practices for the proper planning and execution of a horizontal well. In planning a horizontal well, the optimal method and technology for building inclination and extending the lateral section must be determined. Properly specified logging-while-drilling tools are essential to keep the wellbore within the target formation. Planning must also focus on casing design. Doing so will help ensure stability and enable reliable and productive completions. Shales pose a challenge for these elements of well planning due to their thin strata and potentially low mechanical competence when foreign fluids are introduced. Once a plan is developed, executing it is even more important to prove a viable exploration program. Fast, efficient drilling with wellbore control and minimal torque and drag should be the priority. This may be achieved by focusing on fluid hydraulics and rheology and bottom hole assembly. Managed pressure drilling (MPD) will help fast drilling, well control and stability. If MPD can be combined with new generation rotary steerable systems that allow the drill string to maintain rotation, impressive efficiencies are possible. Modern drilling parameter analysis represents the newest opportunity for executing shale gas horizontal wells. A method for ROP analysis to improve operational parameters and equipment selection is also proposed.

  4. Planetary protection in the framework of the Aurora exploration program

    Science.gov (United States)

    Kminek, G.

    The Aurora Exploration Program will give ESA new responsibilities in the field of planetary protection. Until now, ESA had only limited exposure to planetary protection from its own missions. With the proposed ExoMars and MSR missions, however, ESA will enter the realm of the highest planetary protection categories. As a consequence, the Aurora Exploration Program has initiated a number of activities in the field of planetary protection. The first and most important step was to establish a Planetary Protection Working Group (PPWG) that is advising the Exploration Program Advisory Committee (EPAC) on all matters concerning planetary protection. The main task of the PPWG is to provide recommendations regarding: Planetary protection for robotic missions to Mars; Planetary protection for a potential human mission to Mars; Review/evaluate standards & procedures for planetary protection; Identify research needs in the field of planetary protection. As a result of the PPWG deliberations, a number of activities have been initiated: Evaluation of the Microbial Diversity in SC Facilities; Working paper on legal issues of planetary protection and astrobiology; Feasibility study on a Mars Sample Return Containment Facility; Research activities on sterilization procedures; Training course on planetary protection (May, 2004); Workshop on sterilization techniques (fall 2004). In parallel to the PPWG, the Aurora Exploration Program has established an Ethical Working Group (EWG). This working group will address ethical issues related to astrobiology, planetary protection, and manned interplanetary missions. The recommendations of the working groups and the results of the R&D activities form the basis for defining planetary protection specification for Aurora mission studies, and for proposing modification and new inputs to the COSPAR planetary protection policy. Close cooperation and free exchange of relevant information with the NASA planetary protection program is strongly

    2001-01-01

    We present recent work on the development Java PathExplorer (JPAX), a tool for monitoring the execution of Java programs. JPAX can be used during program testing to gain increased information about program executions, and can potentially furthermore be applied during operation to survey safety critical systems. The tool facilitates automated instrumentation of a program's late code which will then omit events to an observer during its execution. The observer checks the events against user provided high level requirement specifications, for example temporal logic formulae, and against lower level error detection procedures, for example concurrency related such as deadlock and data race algorithms. High level requirement specifications together with their underlying logics are defined in the Maude rewriting logic, and then can either be directly checked using the Maude rewriting engine, or be first translated to efficient data structures and then checked in Java.

    1998-02-01

    Mark Twain once quipped that everyone talks about the weather but no one does anything about it. With interest in global climate change on the rise, researchers in the fossil-energy sector are feeling the heat to provide new technology to permit continued use of fossil fuels but with reduced emissions of so-called 'greenhouse gases.' Three important greenhouse gases, carbon dioxide, methane, and nitrous oxide, are released to the atmosphere in the course of recovering and combusting fossil fuels. Their importance for trapping radiation, called forcing, is in the order given. In this report, we briefly review how greenhouse gases cause forcing and why this has a warming effect on the Earth's atmosphere. Then we discuss programs underway at FETC that are aimed at reducing emissions of methane and carbon dioxide

    By sparking interest in scientific inquiry and engineering design at a young age through exposure to ocean exploration and innovative technologies, and building on that interest throughout students' educational careers, the Ocean Exploration Trust (OET) aims to motivate more students to be lifelong learners and pursue careers in STEM fields. Utilizing research conducted aboard Exploration Vessel Nautilus, the ship's associated technologies, and shore-based facilities at the University of Rhode Island — including the Graduate School of Oceanography and the Inner Space Center — we guide students to early career professionals through a series of educational programs focused on STEM disciplines and vocational skills. OET also raises public awareness of ocean exploration and research through a growing online presence, live streaming video, and interactions with the team aboard the ship 24 hours a day via the Nautilus Live website (www.nautiluslive.org). Annually, our outreach efforts bring research launched from Nautilus to tens of millions worldwide and allow the public, students, and scientists to participate in expeditions virtually from shore. We share the Nautilus Exploration Program's strategies, successes, and lessons learned for a variety of our education and outreach efforts including: 1) enabling global audiences access to live ocean exploration online and via social media; 2) engaging onshore audiences in live and interactive conversations with scientists and engineers on board; 3) engaging young K-12 learners in current oceanographic research via newly developed lessons and curricula; 4) onshore and offshore professional development opportunities for formal and informal educators; 5) programs and authentic research opportunities for high school, undergraduate, and graduate students onshore and aboard Nautilus; and 6) collaborative opportunities for early career and seasoned researchers to participate virtually in telepresence-enabled, interdisciplinary

  9. Gas quality analysis and evaluation program for project Gasbuggy

    1970-05-01

    Experimental results of the gas quality analysis program for Project Gasbuggy through August 1969 are presented graphically, addressing the questions raised by the preshot program goals. The chemical composition and the concentrations of tritium, krypton-85, carbon-14 and argon-37, 39 are presented as a function of time and gas production from the nuclear chimney. Chemically, the presence of CO{sub 2}, CO and H{sub 2} served to dilute the formation gas and caused reactions which significantly altered the gas composition at early times. The radionuclide content of the chimney gas at reentry was some 800 pCi/cm{sup 3} of which about 80% was CH{sub 3}T. Lesser quantities of tritium were observed as HT, C{sub 2}H{sub 5}T and C{sub 3}H{sub 7}T. The other major contaminant was Kr{sup 85} which was present at about one-fifth the level of CH{sub 3}T. Small quantities of carbon-14 and argon-39 were also identified. The only other radionuclides identified in the gas were relatively short-lived rare gases. During the production testing, about two and one-half chimney volumes of gas at formation pressure were removed. This removal, accompanied by dilution, has reduced the radionuclide concentrations to about 7% of their levels at reentry. The production characteristics of the Gasbuggy environment prevented an adequate test of the effectiveness of chimney flushing. However, the rapid drawdown concept is supported by the available data as an effective means of reducing contaminant levels. The changes in composition during production or testing are seen to be consistent with a model involving a non-uniform gas influx rate and flow distribution over the chimney region. Mixing times are estimated to be on the order of a few days, so that increasing concentrations following a sudden gas influx can be explained. (author)

  11. China's natural gas exploration and development strategies under the new normal

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available China's natural gas industry has experienced a great leap-forward development in the past decade. Since the second half of 2014, however, international oil price has dropped sharply and global oil and gas markets have been sluggish. In China, economy growth rate slows down and resource environments tend to be more restricted. And energy production and consumption revolution speed up, and the development of natural gas industry experience profound changes internally and externally. Through review on the achievements in recent high-speed development and analysis on the future development of China's natural gas industry, it is believed that the growth rates of China's natural gas output and consumption will slow down and the supply and demand fundamentals present loose states. Low-permeability tight, deep–extra deep and unconventional reservoirs will be the principal targets of natural gas exploration and development and the tendency of resource deterioration is inevitable. The pressure to the decrease of gas price rises due to the sustained recession of oil price and the sharp decrease of alternative energy price. The normal means to increase benefits is to control investment strictly and reduce cost greatly. As for the new normal, five suggestions are proposed for natural gas exploration and development in China. Firstly, reinforce exploration continuously by guaranteeing work load and investment at the required level, and tamp the development basis. Secondly, pay much attention to early development evaluation, give prominence to plan implementation design and control productivity construction rhythm. Thirdly, pay attention to the top-level design of mature gas field development and adjustment, with fine description and management as the priority, and improve overall development level. Fourthly, strengthen the researches on exploration and development technologies, with the simplification and practicability of technologies as the focus, and

    1999-01-01

    Operations in the oil and gas industry that involve exploration and production on Aboriginal lands are definitely more complex than operations on provincial Crown lands and there is clearly a need to meet different objectives. There are many good reasons for a petroleum exploration company to make a risk investment on First Nation lands, and the governing legislation permits considerable latitude in the terms of exploration permits and production leases. Indian Oil and Gas Canada will have to approve any agreement negotiated with a First Nation, so they must be made part of the deal-making process. It is important to recognize the responsibility a company has as a partner of a First Nation to help them achieve the maximum benefits from this non-renewable resource. Aspects considered include: the participants and their needs; terms and conditions in oil and gas leases; innovative compensation models; marketing the royalty share; equity participation, and managing exploration and development risk

    Williams, Christine L; Kilanski, Kristine; Muller, Chandra

    2014-11-01

    Since the 1980s, major U.S. corporations have embraced diversity as a management strategy to increase the number of women in top jobs. Diversity management programs include targeted recruitment, hiring, and promotions policies; mentoring programs; affinity groups; and diversity training. Few of these programs have proven effective in achieving gender diversity in the corporate world, despite their widespread popularity. To explore the reasons for this, the authors investigate the experiences of women scientists in the oil and gas industry who are targeted by these programs. In-depth interviews reveal possible reasons why these programs fail to achieve their intended goals. The authors find that these programs can paradoxically reinforce gender inequality and male dominance in the industry. The authors discuss alternative approaches for addressing gender inequality in work organizations and conclude with implications of their findings for corporate approaches to promoting diversity and for future research.

  14. Exploring efficacy of residential energy efficiency programs in Florida

    Science.gov (United States)

    Taylor, Nicholas Wade

    Electric utilities, government agencies, and private interests in the U.S. have committed and continue to invest substantial resources in the pursuit of energy efficiency and conservation through demand-side management (DSM) programs. Program investments, and the demand for impact evaluations that accompany them, are projected to grow in coming years due to increased pressure from state-level energy regulation, costs and challenges of building additional production capacity, fuel costs and potential carbon or renewable energy regulation. This dissertation provides detailed analyses of ex-post energy savings from energy efficiency programs in three key sectors of residential buildings: new, single-family, detached homes; retrofits to existing single-family, detached homes; and retrofits to existing multifamily housing units. Each of the energy efficiency programs analyzed resulted in statistically significant energy savings at the full program group level, yet savings for individual participants and participant subgroups were highly variable. Even though savings estimates were statistically greater than zero, those energy savings did not always meet expectations. Results also show that high variability in energy savings among participant groups or subgroups can negatively impact overall program performance and can undermine marketing efforts for future participation. Design, implementation, and continued support of conservation programs based solely on deemed or projected savings is inherently counter to the pursuit of meaningful energy conservation and reductions in greenhouse gas emissions. To fully understand and optimize program impacts, consistent and robust measurement and verification protocols must be instituted in the design phase and maintained over time. Furthermore, marketing for program participation must target those who have the greatest opportunity for savings. In most utility territories it is not possible to gain access to the type of large scale

    2015-11-01

    Full Text Available Natural gas resources is abundant in the Ordos Basin, where six gas fields with more than 100 billion cubic meters of gas reserves have been successively developed and proved, including Jingbian, Yulin, Zizhou, Wushenqi, Sulige and Shenmu. This study aims to summarize the fruitful results and functional practices achieved in the huge gas province exploration, which will be regarded as guidance and reference for the further exploration and development in this basin. Based on the past five decades' successful exploration practices made by PetroChina Changqing Oilfield Company, we first comb the presentation of geological theories at different historical stages as well as the breakthrough in the course. Then, we analyze a complete set of adaptive techniques obtained from the long-time technological research and conclude historical experiences and effective measures in terms of broadening exploration ideas, such as the fluvial delta reservoir-forming theory, giant tight gas reservoir-forming theory, the idea of sediment source system in the southern basin, etc., and innovating technical and management mechanism, such as all-digit seismic prediction, fine logging evaluation for gas formations, stimulation of tight sand reservoirs, flat project and benchmarking management, and so on.

  16. A summary description of the flammable gas tank safety program

    International Nuclear Information System (INIS)

    Johnson, G.D.; Sherwood, D.J.

    1994-10-01

    Radioactive liquid waste may produce hydrogen as result of the interaction of gamma radiation and water. If the waste contains organic chelating agents, additional hydrogen as well as nitrous oxide and ammonia may be produced by thermal and radiolytic decomposition of these organics. Several high-level radioactive liquid waste storage tanks, located underground at the Hanford Site in Washington State, are on a Flammable Gas Watch List. Some contain waste that produces and retains gases until large quantities of gas are released rapidly to the tank vapor space. Tanks nearly-filled to capacity have relatively little vapor space; therefore if the waste suddenly releases a large amount of hydrogen and nitrous oxide, a flammable gas mixture could result. The most notable example of a Hanford waste tank with a flammable gas problem is tank 241-SY-101. Upon occasion waste stored in this tank has released enough flammable gas to burn if an ignition source had been present inside of the tank. Several, other Hanford waste tanks exhibit similar behavior although to a lesser magnitude. Because this behavior was hot adequately-addressed in safety analysis reports for the Hanford Tank Farms, an unreviewed safety question was declared, and in 1990 the Flammable Gas Tank Safety Program was established to address this problem. The purposes of the program are a follows: (1) Provide safety documents to fill gaps in the safety analysis reports, and (2) Resolve the safety issue by acquiring knowledge about gas retention and release from radioactive liquid waste and developing mitigation technology. This document provides the general logic and work activities required to resolve the unreviewed safety question and the safety issue of flammable gas mixtures in radioactive liquid waste storage tanks

    This research into new packaging materials and methods for elevated temperatures and harsh environment electronics focused on gaining a basic understanding of current state-of-the-art in electronics packaging used in industry today, formulating the thermal-mechanical models of the material interactions and developing test structures to confirm these models. Discussions were initiated with the major General Electric (GE) businesses that currently sell into markets requiring high temperature electronics and packaging. They related the major modes of failure they encounter routinely and the hurdles needed to be overcome in order to improve the temperature specifications of these products. We consulted with our GE business partners about the reliability specifications and investigated specifications and guidelines that from IPC and the SAE body that is currently developing guidelines for electronics package reliability. Following this, a risk analysis was conducted for the program to identify the critical risks which need to be mitigated in order to demonstrate a flex-based packaging approach under these conditions. This process identified metal/polyimide adhesion, via reliability for flex substrates and high temperature interconnect as important technical areas for reliability improvement.

    As NASA moves toward expanded commercial spaceflight within its human exploration capability, there is increased emphasis on how to allocate responsibilities between government and commercial organizations to achieve coordinated program objectives. The practice of program-level functional analysis offers an opportunity for improved understanding of collaborative functions among heterogeneous partners. Functional analysis is contrasted with the physical analysis more commonly done at the program level, and is shown to provide theoretical performance, risk, and safety advantages beneficial to a government-commercial partnership. Performance advantages include faster convergence to acceptable system solutions; discovery of superior solutions with higher commonality, greater simplicity and greater parallelism by substituting functional for physical redundancy to achieve robustness and safety goals; and greater organizational cohesion around program objectives. Risk advantages include avoidance of rework by revelation of some kinds of architectural and contractual mismatches before systems are specified, designed, constructed, or integrated; avoidance of cost and schedule growth by more complete and precise specifications of cost and schedule estimates; and higher likelihood of successful integration on the first try. Safety advantages include effective delineation of must-work and must-not-work functions for integrated hazard analysis, the ability to formally demonstrate completeness of safety analyses, and provably correct logic for certification of flight readiness. The key mechanism for realizing these benefits is the development of an inter-functional architecture at the program level, which reveals relationships between top-level system requirements that would otherwise be invisible using only a physical architecture. This paper describes the advantages and pitfalls of functional analysis as a means of coordinating the actions of large heterogeneous organizations

  19. Implementing a Science-driven Mars Exploration Program

    2001-12-01

    NASA's newly restructured Mars Exploration Program (MEP) was developed on the basis of the goals, objectives, investigations, and prioritizations established by the Mars Exploration Payload Analysis Group (as summarized previously by Greeley et al., 2001). The underlying scientific strategy is linked to common threads which include the many roles water has played on and within Mars as a "system". The implementation strategy that has been adopted relies heavily on an ever-sharpening program of reconnaissance, beginning with the legacy of the Mars Global Surveyor, continuing with the multispectral and compositional observations of the Mars Odyssey orbiter, and extending to a first step in surface-based reconnaissance with the 2003 Mars Exploration Rovers. The results of MGS and Odyssey will serve to focus the trade space of localities where the record, for example, of persistent surface water may have been preserved in a mineralogical sense. The 2005 Mars Reconnaissance Orbiter will further downselect the subset of sites on Mars where evidence of depositional patterns and aqueous mineralogies (i.e., diagenetic minerals) are most striking at scales as fine as tens to hundreds of meters. Reconnaissance will move to the surface and shallow subsurface in 2007 with the Mars "Smart Lander" (MSL), at which time an extensive array of mobile scientific exploration tools will be used to examine a locality at 10km traverse scales, ultimately asking scientific questions which can be classed as paleobiological (i.e., life inference). Further orbital reconnaissance may be undertaken in 2009, perhaps involving targeted multi-wavelength SAR imaging, in anticipation of a precisely targeted Mars Sample Return mission as early as 2011. This sequence of core program MEP missions will be amplified by the selection of PI-led SCOUT missions, starting in 2007, and continuing every other Mars launch opportunity.

  20. The gas release programs to increase competition in the European gas market

    International Nuclear Information System (INIS)

    Clastres, Cedric

    2005-01-01

    Regulators have implemented asymmetric regulation measures, such as gas release programs and market share targets, because of European gas supply features and gas market specificities. Empirical experiences show in line with economic theory that these regulation measures favour entry and competition without deterring investments. If we look at impacts on competition, they are mitigated. Some positive effects result from the increase in consumption or in importation and transportation infrastructure developments. But these regulations can also encourage anti-competitive behaviours like collusion, cream-skimming, reverse cherry picking or inefficient entries. Gas release measures establish a link between the incumbent and its competitors. A system of constraints on operators capacities can also appear. Thus, pricing or quantity strategies are more complex. Equilibrium prices are more volatile and very different of competition mark-up. The incumbent, for high gas release quantities and low supplies, can increase its costs to make more profit. This Raising Rivals' Costs strategy often occur if the gas release price is closer to supply costs. This strategy does not impact on consumers surplus but decreases welfare. The regulator can restore incentives to efficiency by setting gas release proportion function of incumbent's supplies. This proportion must be high enough to have a positive impact on the market because of incumbent's incentives to efficiency and greater total quantities sold by the two operators. But, on another way, it must not be too high as it could, thus, increase the probability of Raising Rivals' Costs or favour collusive strategies. (author) [fr

    Haurie, A.; Smeers, Y.; Zaccour, G.

    1991-01-01

    This paper deals with a stochastic programming model which complements long range market simulation models generating scenarios concerning the evolution of demand and prices for gas in different market segments. Agas company has to negociate contracts with lengths going from one to twenty years. This stochastic model is designed to assess the risk associated with committing the gas production capacity of the company to these market segments. Different approaches are presented to overcome the difficulties associated with the very large size of the resulting optimization problem

    The purpose of this ethnographic study was to explore and describe women's participation in a U.S. microcredit program in the Pacific Northwest and to examine the relationship between the participants' businesses and their health. In 2006, an ethnographic study was conducted with a microcredit organization in the Pacific Northwest using the following methods: (a) 10 audiotaped, semistructured interviews with clientele; (b) observation of microcredit groups four times a month for 6 months; (c) conversations with organization executive directors; and (d) review of organizational documents. The participants were women 32 to 64 years of age who had received one or more loans from the microcredit organization. Four broad themes emerged from the data: (a) Microcredit: The introduction; (b) Microcredit: The place; (c) Stereotypes; and (d) Health. Despite the challenges associated with participation, all of the study participants were enthusiastic about the advantages of microcredit and would recommend it to others. Many international microcredit organizations have incorporated health care and health education into their programs and have reported successful economic and social outcomes for women. In the United States (US), reports are varied, and there is a lack of literature that explores the economic and health link that is addressed in some international microcredit literature. The findings from this study might be used to initiate discussions around conjoint health education programs and microcredit as a health intervention. Nurses, as a trusted presence in the community, are in a position to partner with microcredit organizations to improve the health of clientele.

    2008-01-01

    This report contains maps and associated spatial data showing historical oil and gas exploration and production in the United States. Because of the proprietary nature of many oil and gas well databases, the United States was divided into cells one-quarter square mile and the production status of all wells in a given cell was aggregated. Base-map reference data are included, using the U.S. Geological Survey (USGS) National Map, the USGS and American Geological Institute (AGI) Global GIS, and a World Shaded Relief map service from the ESRI Geography Network. A hardcopy map was created to synthesize recorded exploration data from 1859, when the first oil well was drilled in the U.S., to 2005. In addition to the hardcopy map product, the data have been refined and made more accessible through the use of Geographic Information System (GIS) tools. The cell data are included in a GIS database constructed for spatial analysis via the USGS Internet Map Service or by importing the data into GIS software such as ArcGIS. The USGS internet map service provides a number of useful and sophisticated geoprocessing and cartographic functions via an internet browser. Also included is a video clip of U.S. oil and gas exploration and production through time.

    2017-10-01

    This study examines science interests, efficacy, attitudes, and identity—referred to as affinities, in the context of an informal science outreach program for girls. A mixed methods design was used to explore girls' science affinities before, during, and after participation in a cohort-based summer science camp. Multivariate analysis of survey data revealed that girls' science affinities varied as a function of the joint relationship between family background and number of years in the program, with girls from more affluent families predicted to increase affinities over time and girls from lower income families to experience initial gains in affinities that diminish over time. Qualitative examination of girls' perspectives on gender and science efficacy, attitudes toward science, and elements of science identities revealed a complex interplay of gendered stereotypes of science and girls' personal desires to prove themselves knowledgeable and competent scientists. Implications for the best practice in fostering science engagement and identities in middle school-aged girls are discussed.

  6. Exploration and production of crude oil and natural gas in Germany in 2012

    Pasternak, Michael

    2013-01-01

    This article presents an overview of oil and gas exploration and production in Germany in 2012. The report is based on data gathered on a regular basis by the State Authority for Mining, Energy and Geology (LBEG) from the oil and gas companies and the other state mining offices. Due to the granting of new licences in the last years, a significant increase of geophysical prospecting of the subsurface for oil and gas deposits was observed. Six 3D seismic surveys were conducted. Five surveys were located in the Upper Rhine Valley and one in the lowlands of Northwest Germany. 2D seismic data were acquired in Lusatia (Brandenburg) and at the coast of the Baltic Sea. The number of exploration wells decreased once again. In 2012 nine exploration wells were drilled, compared to ten in the previous year. In addition to that number, another seven exploration wells were drilled to total depth already before 2012, but not completed by final well results in 2012. None of the ten new field wildcats were completed by result. Three exploration wells (appraisal wells) were completed successfully. Two of these wells confirmed the presence of gas and one the presence of oil. The number of development wells decreased significantly. In 2012 31 wells were drilled, compared to 46 in the prominent year 2011. Another 13 wells were drilled to total depth already before 2012, but not completed by final well results in 2012. 31 wells were completed successfully. 30 of these wells encountered oil or gas pay zones. In 2011 drilling meterage has reached its highest value since 1998. In contrast the total drilling meterage decreased slightly by less than 2000 m to 71,424 min 2012. The natural gas production continued its downward trend. Due to the depletion of gas fields, the annual natural gas production dropped by 9.1% compared to the previous year and amounted to 11.7 billion m 3 (field quality). After the increase in 2011, the annual crude oil production decreased by 2.1% to 2.6 million t

    The Mount Elbert Gas Hydrate Stratigraphic Test Well was drilled within the Alaska North Slope (ANS) Milne Point Unit (MPU) from February 3 to 19, 2007. The well was conducted as part of a Cooperative Research Agreement (CRA) project co-sponsored since 2001 by BP Exploration (Alaska), Inc. (BPXA) and the U.S. Department of Energy (DOE) in collaboration with the U.S. Geological Survey (USGS) to help determine whether ANS gas hydrate can become a technically and commercially viable gas resource. Early in the effort, regional reservoir characterization and reservoir simulation modeling studies indicated that up to 0.34 trillion cubic meters (tcm; 12 trillion cubic feet, tcf) gas may be technically recoverable from 0.92 tcm (33 tcf) gas-in-place within the Eileen gas hydrate accumulation near industry infrastructure within ANS MPU, Prudhoe Bay Unit (PBU), and Kuparuk River Unit (KRU) areas. To further constrain these estimates and to enable the selection of a test site for further data acquisition, the USGS reprocessed and interpreted MPU 3D seismic data provided by BPXA to delineate 14 prospects containing significant highly-saturated gas hydrate-bearing sand reservoirs. The "Mount Elbert" site was selected to drill a stratigraphic test well to acquire a full suite of wireline log, core, and formation pressure test data. Drilling results and data interpretation confirmed pre-drill predictions and thus increased confidence in both the prospect interpretation methods and in the wider ANS gas hydrate resource estimates. The interpreted data from the Mount Elbert well provide insight into and reduce uncertainty of key gas hydrate-bearing reservoir properties, enable further refinement and validation of the numerical simulation of the production potential of both MPU and broader ANS gas hydrate resources, and help determine viability of potential field sites for future extended term production testing. Drilling and data acquisition operations demonstrated that gas hydrate

    2013-01-01

    The introduction of smart metering is one of the core elements in recent European policies targeting environmental sustainability and competitiveness of energy markets. Following the roll-out of smart electricity meters, in 2008 the Italian regulator designed an ambitious deployment program also for smart gas meters, that was recently modified in both scope and timing. This paper assesses Italy's original and current deployment plans, with a specific focus on the results of its cost–benefit analysis. In light of the evidence derived from the literature, we observe that the case for the roll-out of smart gas meters in Italy was not supported by a strong emphasis on energy savings but rather focused on increasing efficiency of the Italian gas market; in this respect, we argue that options other than smart gas metering should also be considered. Moreover the Italian cost–benefit analysis, which mostly dealt with the potential cost savings for distributors and suppliers, led to ambiguous results in terms of net present values; thus, we believe that an updated assessment would be extremely useful. Finally, in terms of technological choices, our analysis positively evaluates the regulator's recent proposal to consider a dual-fuel solution for the mass market deployment. - Highlights: • This paper assesses Italy's original and current deployment plans for smart gas meters. • The plan was not supported by a strong emphasis on energy savings. • A focus on increasing efficiency of the Italian gas market appears only partly justifiable. • The business case for adopting smart gas meters should be updated. • Our analysis positively evaluates the a dual-fuel solution for the mass market

    The Mississippi Office of Geology has conducted field trials using the surface exploration techniques of geomicrobial, radiometrics, and free soil gas. The objective of these trials is to determine if Mississippi oil and gas fields have surface hydrocarbon expression resulting from vertical microseepage migration. Six fields have been surveyed ranging in depth from 3,330 ft to 18,500 ft. The fields differ in trapping styles and hydrocarbon type. The results so far indicate that these fields do have a surface expression and that geomicrobial analysis as well as radiometrics and free soil gas can detect hydrocarbon microseepage from pressurized reservoirs. All three exploration techniques located the reservoirs independent of depth, hydrocarbon type, or trapping style.

    2011-01-01

    Costs and benefits of building energy efficiency are estimated as a means of reducing greenhouse gas emissions in Pittsburgh, PA and Austin, TX. The analysis includes electricity and natural gas consumption, covering 75% of building energy consumption in Pittsburgh and 85% in Austin. Two policy objectives were evaluated: maximize GHG reductions given initial budget constraints or maximize social savings given target GHG reductions. This approach evaluates the trade-offs between three primary and often conflicting program design parameters: initial capital constraints, social savings, and GHG reductions. Results suggest uncertainty in local stocks, demands, and efficiency significantly impacts anticipated outcomes. Annual GHG reductions of 1 ton CO 2 eq/capita/yr in Pittsburgh could cost near nothing or over $20 per capita annually. Capital-constrained policies generate slightly less social savings (a present value of a few hundred dollars per capita) than policies that maximize social savings. However, sectors and end uses targeted for intervention vary depending on policy objectives and constraints. Optimal efficiency investment strategies for some end uses vary significantly (in excess of 100%) between Pittsburgh and Austin, suggesting that resources and guidance conducted at the national scale may mislead state and local decision-makers. Results are used to provide recommendations for efficiency program administrators. - Highlights: → We use public data to estimate local building energy costs, benefits and greenhouse gas reductions. → We use optimization to evaluate trade-offs between program objectives and capital constraints. → Local energy market conditions significantly influence efficiency expectations. → Different program objectives can lead to different effective investment strategies. → We reflect on the implications of our results for efficiency program design.

  13. Advancing New 3D Seismic Interpretation Methods for Exploration and Development of Fractured Tight Gas Reservoirs

    James Reeves

    2005-01-31

    In a study funded by the U.S. Department of Energy and GeoSpectrum, Inc., new P-wave 3D seismic interpretation methods to characterize fractured gas reservoirs are developed. A data driven exploratory approach is used to determine empirical relationships for reservoir properties. Fractures are predicted using seismic lineament mapping through a series of horizon and time slices in the reservoir zone. A seismic lineament is a linear feature seen in a slice through the seismic volume that has negligible vertical offset. We interpret that in regions of high seismic lineament density there is a greater likelihood of fractured reservoir. Seismic AVO attributes are developed to map brittle reservoir rock (low clay) and gas content. Brittle rocks are interpreted to be more fractured when seismic lineaments are present. The most important attribute developed in this study is the gas sensitive phase gradient (a new AVO attribute), as reservoir fractures may provide a plumbing system for both water and gas. Success is obtained when economic gas and oil discoveries are found. In a gas field previously plagued with poor drilling results, four new wells were spotted using the new methodology and recently drilled. The wells have estimated best of 12-months production indicators of 2106, 1652, 941, and 227 MCFGPD. The latter well was drilled in a region of swarming seismic lineaments but has poor gas sensitive phase gradient (AVO) and clay volume attributes. GeoSpectrum advised the unit operators that this location did not appear to have significant Lower Dakota gas before the well was drilled. The other three wells are considered good wells in this part of the basin and among the best wells in the area. These new drilling results have nearly doubled the gas production and the value of the field. The interpretation method is ready for commercialization and gas exploration and development. The new technology is adaptable to conventional lower cost 3D seismic surveys.

    Dr. Ronald C. Surdam

    1999-01-01

    A primary objective of the Institute for Energy Research (IER)-Santa Fe Snyder Corporation DOE Riverton Dome project is to test the validity of a new conceptual model and resultant exploration paradigm for so-called ''basin center'' gas accumulations. This paradigm and derivative exploration strategy suggest that the two most important elements crucial to the development of prospects in the deep, gas-saturated portions of Rocky Mountain Laramide Basins (RMLB) are (1) the determination and, if possible, three-dimensional evaluation of the pressure boundary between normal and anomalous pressure regimes (i.e., this boundary is typically expressed as a significant inversion in both sonic and seismic velocity-depth profiles) , and (2) the detection and delineation of porosity/permeability ''sweet spots'' (i.e., areas of enhanced storage capacity and deliverability) in potential reservoir targets below this boundary. There are other critical aspects in searching for basin center gas accumulations, but completion of these two tasks is essential to the successful exploration for the unconventional gas resources present in anomalously pressured rock/fluid systems in the Rocky Mountain Laramide Basins. The southern Wind River Basin, in particular the Riverton Dome and Emigrant areas, is a neat location for testing this exploration paradigm. Preliminary work within the Wind River Basin has demonstrated that there is a regionally prominent pressure surface boundary that can be detected by inversions in sonic velocity depth gradients in individual well log profiles and that can be seen as a velocity inversion on seismic lines. Also, the Wind River Basin in general-and the Riverton Dome area specially-is characterized by a significant number of anomalously pressured gas accumulations. Most importantly, Santa Fe Snyder Corporation has provided the study with sonic logs, two 3-D seismic studies (40 mi(sup 2) and 30 mi(sup 2)) and a variety of other necessary geological and

    Oil and gas exploration is a unique kind of business. Businesses providing a vast and ever-changing panoply of products to markets are a focus of several disciplines' energetic study and analysis. The product inventory problem is robust, pertinent, and meaningful, and it merits the voluminous and protracted attention received from keen business practitioners. Prototypical business practitioners, be they trained by years of business hurly-burly, or sophisticated MBAs with arrays of mathematical algorithms and computers, are not normally prepared, however, to recognize the unique nature of exploration's inventories. Put together such a business practitioner with an explorationist and misunderstandings, hidden and open, are inevitable and predictably rife. The first purpose of this paper is to articulate the inherited inventory handling paradigms of business practitioners in relation to exploration's inventories. To do so, standard pedagogy in business administration is used and a case study of an exploration venture is presented. A second purpose is to show the burdens that the misunderstandings create. The result is not just business plans that go awry, but public policies that have effects opposite from those intended

    Baker, G.F.

    1993-01-01

    Since the passage of the Clean Air Act Amendments in 1990, there has been increasing interest among regulators and business interests alike in innovative, market-based strategies to air quality control. In particular, larger metropolitan areas have begun to examine marketable emission reduction credit (ERC) programs. These programs limit the total allowable emissions in a non-attainment area, allocate these emission open-quotes creditsclose quotes among sources in the region, and allow the sources to redistribute their allowances through trading. This approach provides for the most cost-effective distribution of control burdens among affected sources, taking advantage of the differences in marginal control costs. Some control measures applied to mobile sources may be significantly less expensive than those applied to stationary sources, making mobile sources an excellent candidate for inclusion in an ERC program. However, there are several potential problems involving quantification, enforcement, and credit trading issues that hinder the development of mobile source ERC programs. This paper will evaluate those obstacles and discuss how they are being addressed in a Natural Gas Vehicle (NGV) program currently under development for the Houston ozone non-attainment area. Specifically, the study will outline the credit validation (i.e., quantification) procedure, including baseline emission determination and emission testing for each NGV in the program. In addition, the study will describe the vehicle/fuel consumption tracking system, and discuss issues related to credit trading with stationary sources. Finally, observations are made concerning the applicability of mobile ERC programs for other emission control measures such as old vehicle scrappage and vehicle Inspection and Maintenance programs

    Natural gas and renewable energy each contribute to economic growth, energy independence, and carbon mitigation, sometimes independently and sometimes collectively. Often, natural gas and renewables are considered competitors in markets, such as those for bulk electricity. This paper attempts to address the question, 'Given near- and long-term needs for abundant, cleaner energy sources and decarbonization, how can more compelling business models be created so that these two domestic forms of energy work in greater concert?' This paper explores revenue opportunities that emerge from systems-level perspectives in 'bulk energy' (large-scale electricity and natural gas production, transmission, and trade) and four 'distribution edge' subsectors: industrial, residential, commercial, and transportation end uses.

    This document has been developed for the nontechnical gas industry manager who has the responsibility for the development of waste or potentially contaminated soil and groundwater data or must make decisions based on such data for the management or remediation of these materials. It explores the pse of common analytical chemistry instrumentation and associated techniques for identification of environmentally hazardous materials. Sufficient detail is given to familiarize the nontechnical reader with the principles behind the operation of each technique. The scope and realm of the techniques and their constituent variations are portrayed through a discussion of crucial details and, where appropriate, the depiction of real-life data. It is the author's intention to provide an easily understood handbook for gas industry management. Techniques which determine the presence, composition, and quantification of gas industry wastes are discussed. Greater focus is given to traditional techniques which have been the mainstay of modem analytical benchwork. However, with the continual advancement of instrumental principles and design, several techniques have been included which are likely to receive greater attention in fiture considerations for waste-related detection. Definitions and concepts inherent to a thorough understanding of the principles common to analytical chemistry are discussed. It is also crucial that gas industry managers understand the effects of the various actions which take place before, during, and after the actual sampling step. When a series of sample collection, storage, and transport activities occur, new or inexperienced project managers may overlook or misunderstand the importance of the sequence. Each step has an impact on the final results of the measurement process; errors in judgment or decision making can be costly. Specific techniques and methodologies for the collection, storage, and transport of environmental media samples are not

    The Marine Controlled-Source Electromagnetic (MCSEM) method has been recognized as an important and effective tool to detect electrically resistive structures, such as oil, gas, and gas hydrate. The MCSEM performance is strongly influenced by the transmitter system design. We have developed a deep-tow MCSEM transmitter system. In this paper, some new technical details will be present. A 10,000 m optical-electrical composite cable is used to support high power transmission and fast data transfer; a new clock unit is designed to keep the synchronization between transmitter and receivers, and mark the time stamp into the transmission current full waveform; a data link is established to monitor the real-time altitude of the tail unit; an online insulation measuring instrument is adopted to monitor current leakage from high voltage transformer; a neutrally buoyant dipole antenna of copper cable and flexible electrodes are created to transmit the large power current into seawater; a new design method for the transmitter, which is called "real-time control technology of hardware parallelism", is described to achieve inverting and recording high-power current waveform, controlling functions, and collecting auxiliary information. We use a gas hydrate exploration test to verify the performance of the transmitter system, focusing on more technical details, rather than applications. The test shows that the transmitter can be used for gas hydrate exploration as an effective source.

    Simon, J.

    2005-11-01

    There are 6 natural gas distribution companies in Canada with formal, ratepayer-funded demand side management (DSM) programs. However, the general characteristics and regulatory environment of these companies varies greatly. With the exception of Enbridge Gas and Union Gas, each company is located in a different province, which means that companies face different energy regulations and energy efficiency policies. An introduction to DSM and its regulation in Canada was presented, as well as an overview of common models in Canada, and the general considerations involved in designing a regulatory framework were discussed. Regulatory design options for natural gas demand-side management regulatory frameworks were evaluated. The major factors that influence the frameworks were analyzed, and the characteristics of a successful DSM program were outlined. The research methodology for this paper consisted of telephone interviews with policy-makers, regulators, non-governmental organizations and regulatory affairs personnel from local distribution companies. Results indicated the importance of a clear policy framework that provides direction for DSM designers. The common elements for a successful regulatory framework were considered to be a systems approach to the definition of DSM; clear regulatory rules; a long-term predictable source and level of DSM funding that reflected the maturity of the DSM market; an alignment of government energy policies and DSM regulatory frameworks; and recognition and capturing of the broad range of DSM benefits

    The Fast Ignition (FI) Concept for Inertial Confinement Fusion (ICF) has the potential to provide a significant advance in the technical attractiveness of Inertial Fusion Energy reactors. FI differs from conventional “central hot spot” (CHS) target ignition by decoupling compression from heating: using a laser (or heavy ion beam or Z pinch) drive pulse (10’s of nanoseconds) to create a dense fuel and a second, much shorter (~10 picoseconds) high intensity pulse to ignite a small volume within the dense fuel. The physics of fast ignition process was the focus of our Advanced Concept Exploration (ACE) program. Ignition depends critically on two major issues involving Relativistic High Energy Density (RHED) physics: The laser-induced creation of fast electrons and their propagation in high-density plasmas. Our program has developed new experimental platforms, diagnostic packages, computer modeling analyses, and taken advantage of the increasing energy available at laser facilities to advance understanding of the fundamental physics underlying these issues. Our program had three thrust areas: • Understand the production and characteristics of fast electrons resulting from FI relevant laser-plasma interactions and their dependence on laser prepulse and laser pulse length. • Investigate the subsequent fast electron transport in solid and through hot (FI-relevant) plasmas. • Conduct and understand integrated core-heating experiments by comparison to simulations. Over the whole period of this project (three years for this contract), we have greatly advanced our fundamental understanding of the underlying properties in all three areas: • Comprehensive studies on fast electron source characteristics have shown that they are controlled by the laser intensity distribution and the topology and plasma density gradient. Laser pre-pulse induced pre-plasma in front of a solid surface results in increased stand-off distances from the electron origin to the high density

    Gas hydrate is a naturally occurring “ice-like” combination of natural gas and water that has the potential to serve as an immense resource of natural gas from the world’s oceans and polar regions. However, gas-hydrate recovery is both a scientific and a technical challenge and much remains to be learned about the geologic, engineering, and economic factors controlling the ultimate energy resource potential of gas hydrate. The amount of natural gas contained in the world’s gas-hydrate accumulations is enormous, but these estimates are speculative and range over three orders of magnitude from about 2,800 to 8,000,000 trillion cubic meters of gas. By comparison, conventional natural gas accumulations (reserves and undiscovered, technically recoverable resources) for the world are estimated at approximately 440 trillion cubic meters. Gas recovery from gas hydrate is hindered because the gas is in a solid form and because gas hydrate commonly occurs in remote Arctic and deep marine environments. Proposed methods of gas recovery from gas hydrate generally deal with disassociating or “melting” in situ gas hydrate by heating the reservoir beyond the temperature of gas-hydrate formation, or decreasing the reservoir pressure below hydrate equilibrium. The pace of energy-related gas hydrate assessment projects has accelerated over the past several years.

    The Indian National Gas Hydrate Program Expedition 01 (NGHP-01) is designed to study the occurrence of gas hydrate along the passive continental margin of the Indian Peninsula and in the Andaman convergent margin, with special emphasis on understanding the geologic and geochemical controls on the occurrence of gas hydrate in these two diverse settings. The NGHP-01 expedition established the presence of gas hydrates in the Krishna-Godavari and Mahanadi Basins, and the Andaman Sea. The expedition discovered in the Krishna-Godavari Basin one of the thickest gas hydrate accumulations ever documented, in the Andaman Sea one of the thickest and deepest gas hydrate stability zones in the world, and established the existence of a fully developed gas hydrate petroleum system in all three basins.

    Technological advances in directional drilling and hydraulic fracturing technology have unlocked new supplies of shale gas from reservoirs that were previously considered to be uneconomic. Several companies, both experienced majors and small independents, are currently evaluating the unconventional resource potential of mainland Europe. This paper demonstrated that global sea level changes govern the distribution of marine black shales. The Hallam Curve was used in this study to identify periods of prospective gas shale deposition. In general, these correspond to post-glacial periods of relatively high sea level. Under-filled marginal sedimentary basins are key exploration targets. The geochemical and petrophysical characteristics of the shales deposited under these conditions are often comparable to North American shales, particularly the Barnett Shale which is currently in production. Many orogenic events influence European shales in terms of organic maturity, hydrocarbon generation and fracture generation. The main prospective horizons in ascending stratigraphic sequence are the Alum Shale, Llandovery Shale, Fammenian/Frasnian Shale, Serpukhovian Shale, Toarcian Shale, Kimmeridge Clay and the Tertiary Eocene and Oligocene shales common to central Europe. This paper presented the authors initial exploration strategy, with particular focus on the Lower Palaeozoic of central Europe, the Namurian of northwest England and the Jurassic Posidonia Formation of the Roer Valley Graben in Holland. The potential obstacles to unconventional exploration in Europe include restricted access to surface locations, high water usage, a lack of convenient pipeline infrastructure, strict environmental regulations, a high population density and lack of suitable drilling rigs and well completion equipment. 13 refs., 7 figs.

    2003-01-01

    The offshore petroleum industry in eastern Canada has expanded rapidly, with exploration and production activities taking place over a wide range of oceanographic conditions. This workshop, hosted by Canada's largest marine research institute, was held to advance the understanding of environmental impacts from offshore oil and gas activity. In particular, it examined how information derived from environmental effects monitoring (EEM) programs contribute to improved drilling and production operations, mitigation measures, and the revision of regulations for waste treatment. The workshop examined if EEM programs are providing valuable information, and how they can be improved. The themes of the 3 sessions which focused on ways to carry out EEM were: (1) EEM and environmental management, (2) EEM methodologies and lessons learned, and (3) EEM methodologies and technologies. Participants form around the world identified priority research needs and coordinated collaborative research efforts. Approximately 70 papers and posters were presented at the workshop, of which 19 have been indexed separately for inclusion in this database (Author)

    2016-05-01

    Full Text Available In the Sichuan Basin, the Middle Permian marine carbonate rocks are important natural gas pay zones with immense exploration potential, but the facies belts and distribution situations of layered dolomite reservoirs are not clear, which hinders the progress in natural gas exploration. In view of the sedimentary background of the Sichuan Basin, field outcrop section, drilling data and seismic data were comprehensively analyzed with the favorable reservoir intervals in the framework of sequence stratigraphy as the key research units. Research results about its lithofacies paleogeography were obtained as follows. First, a gentle slope SW high and NE low was presented during the sedimentation of the Qixia Fm in the Middle Permian. In the Maokou Fm of the Middle Permian, however, a series of the N–W trending intra-platform rifts were developed in this setting, and eventually a paleogeographic pattern of NE-dipping alternative uplift and depression was evolved. Second, in the Qixia Fm, the transgressive tract was in an open platform environment and the highstand system tract evolved into a rimmed platform. And the platform margin beach in the area of Jiange–Ya'an is the favorable reservoir facies belt. And third, in the Maokou Fm, the transgressive tract was in the carbonate shelf environment and the highstand system tract evolved into a rimmed platform. And the platform margin reef flat in the area of Jiange–Ya'an and the syneclise margin beach in the area of Yanting–Guang'an are favorable reservoir facies belts. It is concluded that the two grain beach facies belts in the areas of Jiange–Ya'an and Yanting–Guang'an were the favorable zones for the large-scale development of Middle Permian layered dolomite reservoirs and they are the main target of subsequent natural gas exploration.

  18. Environmental legal implications of oil and gas exploration in the Niger Delta of Nigeria

    Science.gov (United States)

    Orubebe, Bibobra Bello

    Nigeria is an African country endowed with a wealth of oil and gas resources, and they are mainly found in the core Niger Delta (home to the Ijaw and Ogoni indigenous, ethnic minorities). Since Great Britain granted Nigeria political independence on October 1, 1960, successive Nigerian governments (military and civilian) have been dominated by the majority ethnic groups (Hausa-Fulani, Yoruba, and Ibo). Significantly, the government adopted a socialist-based model of absolute state ownership over oil and gas resources. The socialist model formed the basis of Nigeria's business collaboration with multinational oil and gas corporations from Europe and the United States (notably Shell, Chevron Texaco, Agip, Exxon Mobil, Total, and Elf). This model is fraught with contradictions and has led to unacceptable consequences, including policies that allow exploitation of natural resources without reference to environmental sustainability. When oil was first struck in 1956 at Oloibori (Ijaw area), people thought it would bring prosperity and an improved quality of life. Sadly, the opposite has occurred. Forty-nine years of hardship, agonizing pain, debilitating anger, extreme poverty, poisoned rivers, destroyed occupations, devastated environment, and stunted growth of the youth are the negative impacts of oil and gas exploitation in the Niger Delta. In other words, oil and gas exploration and production have visited a full range of evils---socio-political, economic, and cultural---upon the indigenous Niger Delta people. Furthermore, the wealth extracted from the area is used by the state and multinational corporations to enhance their own wealth and quality of life. Revenue has been conspicuously looted and misappropriated by political leaders at the expense of the Niger Delta environment and its people. This confluence of exploitation and injury has led to social upheavals and armed rebellions, all capable of precipitating the disintegration of the country. In this

  19. Application of high-precision 3D seismic technology to shale gas exploration: A case study of the large Jiaoshiba shale gas field in the Sichuan Basin

    Directory of Open Access Journals (Sweden)

    Zuqing Chen

    2016-03-01

    Full Text Available The accumulation pattern of the marine shale gas in South China is different from that in North America. The former has generally thin reservoirs and complex preservation conditions, so it is difficult to make a fine description of the structural features of shale formations and to reflect accurately the distribution pattern of high-quality shale by using the conventional 2D and 3D seismic exploration technology, which has an adverse effect on the successful deployment of horizontal wells. In view of this, high-precision 3D seismic prospecting focusing on lithological survey was implemented to make an accurate description of the distribution of shale gas sweet spots so that commercial shale gas production can be obtained. Therefore, due to the complex seismic geological condition of Jiaoshiba area in Fuling, SE Sichuan Basin, the observation system of high-precision 3D seismic acquisition should have such features as wide-azimuth angles, small trace intervals, high folds, uniform vertical and horizontal coverage and long spread to meet the needs of the shale gas exploration in terms of structural interpretation, lithological interpretation and fracture prediction. Based on this idea, the first implemented high-precision 3D seismic exploration project in Jiaoshiba area played an important role in the discovery of the large Jiaoshiba shale gas field. Considering that the high-quality marine shale in the Sichuan Basin shows the characteristics of multi-layer development from the Silurian system to the Cambrian system, the strategy of shale gas stereoscopic exploration should be implemented to fully obtain the oil and gas information of the shallow, medium and deep strata from the high-precision 3D seismic data, and ultimately to expand the prospecting achievements in an all-round way to balance the high upstream exploration cost, and to continue to push the efficient shale gas exploration and development process in China.

    Science, technology, engineering, arts and math (STEAM) education integrates science with art, presenting a unique and interesting opportunity to increase accessibility in science for learners. This case study examines an afterschool program grounded in art and science integration. Specifically, I studied the goals of the program, it's implementation and the student experience (thinking, feeling and doing) as they participated in the program. My findings suggest that these programs can be powerful methods to nurture scientific literacy, creativity and emotional development in learners. To do so, this program made connections between disciplines and beyond, integrated holistic teaching and learning practices, and continually adapted programming while also responding to challenges. The program is therefore specially suited to engage the heads, hands and hearts of learners, and can make an important contribution to their learning and development. To conclude, I provide some recommendations for STEAM implementation in both formal and informal learning settings.

    Progress is reported for a program whose goals are to demonstrate an experimental upgraded gas turbine powered automobile which meets the 1978 Federal Emissions Standards, has significantly improved fuel economy, and is competitive in performance, reliability, and potential manufacturing cost with the conventional piston engine powered, compact-size American automobile. Initial running of the upgraded engine took place on July 13, 1976. The engine has proved to be mechanically sound, but has also been seriously deficient in power. Principal program effort has therefore been in the area of diagnostic testing and corrective development. To date, three upgraded engines have been assembled and run in the test cell. Engine 2 was installed in an upgraded vehicle and became operational on January 25, 1977. Special diagnostic instrumentation was installed on Engine 3 to evaluate the compressor, turbine, and hot engine leakage. It was determined that the power deficiency was principally due to problems in the compressor and first stage turbine areas and during this quarter several corrective changes have been initiated. Parts for a fourth engine being built for NASA Lewis have been shipped to NASA for installation of special instrumentation.

    Progress is reported for a program whose goals are to demonstrate an experimental upgraded gas turbine powered automobile which meets the 1978 Federal Emissions Standards, has significantly improved fuel economy, and is competitive in performance, reliability, and potential manufacturing cost with the conventional piston engine powered, compact-size American automobile. Initial running of the upgraded engine took place on July 13, 1976. The engine proved to be mechanically sound, but was also 43% deficient in power. A continuing corrective development effort has to date reduced the power deficiency to 32%. Compressor efficiency was increased 2 points by changing to a 28-channel diffuser and tandem deswirl vanes; improved processing of seals has reduced regenerator leakage from about 5 to 2.5% of engine flow; a new compressor turbine nozzle has increased compressor turbine stage efficiency by about 1 point; and adjustments to burner mixing ports has reduced pressure drop from 2.8 to 2.1% of engine pressure. Key compressor turbine component improvements are scheduled for test during the next quarterly period. During the quarter, progress was also made on development of the Upgraded Vehicle control system; and instrumentation of the fourth program engine was completed by NASA. The engine will be used for development efforts at NASA LeRC.

    The geologic occurrence of gas hydrate deposits along the continental margins of India were investigated in the first expedition of the Indian National Gas Hydrate Program (NGHP). The objective was to determine the regional context and characteristics of the gas hydrate deposits through scientific ocean drilling, logging, and analytical activities. A research drill ship was the platform for the drilling operation. The geological and geophysical studies revealed 2 geologically distinct areas with inferred gas hydrate occurrences, notably the passive continental margins of the Indian Peninsula and along the Andaman convergent margin. The NGHP Expedition 01 focused on understanding the geologic and geochemical controls on the occurrence of gas hydrate in these 2 diverse settings. The study established the presence of gas hydrates in Krishna-Godavari, Mahanadi and Andaman basins. Site 10 in the Krishna-Godavari Basin was discovered to be the one of the richest gas hydrate accumulations yet documented, while site 17 in the Andaman Sea had the thickest and deepest gas hydrate stability zone yet known. The existence of a fully-developed gas hydrate system in the Mahanadi Basin was also discovered. Most of the gas hydrate occurrences discovered during this expedition appeared to contain mostly methane which was generated by microbial processes. However, there was also evidence of a thermal origin for a portion of the gas within the hydrates of the Mahanadi Basin and the Andaman offshore area. Gas hydrate in the Krishna-Godavari Basin appeared to be closely associated with large scale structural features, in which the flux of gas through local fracture systems, generated by the regional stress regime, controlled the occurrence of gas hydrate. 3 refs., 1 tab., 2 figs.

    The industry has, in the past decade, added much more gas than it has produced, resulting in a 36% increase in world reserves. Therefore the resource base is no longer considered a serious constraint in satisfying the industry's needs. Under such circumstances, one may ask the question: is exploration for gas still needed? One way in which we may deal with this major issue would be to analyse the changes that occur in the upstream world, in relation to technology, the general business context and industry's strategies and their potential impact on future trends. Dramatic advancements in exploration technologies have helped to improve success ratios and prediction of fluid, and to open new prospective areas, while also reducing costs. From a State point of view, exploration constitutes a long term objective to contend with natural gas consumption growth without depending too much on imports, or to develop resources for exports. From a company perception, exploration appears as a necessity not only for future growth but also for geographical or geopolitical opportunities. Gas reserve additions will come increasingly from a combination of exploration and production deals. The numerous new opportunities created by a more open business environment will facilitate such developments. (authors)

    Guldmann, J M

    1981-10-01

    This paper presents a modeling methodology for the determination of optimal-curtailment decisions by a gas-distribution utility during a chronic gas-shortage situation. Based on the end-use priority approach, a linear-programming model is formulated, that reallocates the available gas supply among the utility's customers while minimizing fuel switching, unemployment, and utility operating costs. This model is then transformed into a chance-constrained program in order to account for the weather-related variability of the gas requirements. The methodology is applied to the East Ohio Gas Company. 16 references, 2 figures, 3 tables.

    Environmental issues faced by power companies were reviewed from the perspective of a major power company that is very much involved in the competitive revolution now underway in the U.S. The battles fought by the U.S. Generating Company of Bethesda, Maryland with environmental groups in the creation of its Hermiston Generating Plant in Oregon were recounted as an example of the different perspectives and the resulting daily challenges facing utility companies in the United States, problems not unlike those faced by natural gas companies in Canada.The principal problems arose when U.S. Generating was trying to secure financing for the Hermiston plant while being challenged by environmentalists in obtaining National Energy Board (NEB) licence to import Canadian gas. It was recommended that to avoid these types of problems, environmental concerns should be addressed when wells are being constructed, not at later stages when power companies are trying to purchase the gas. Several measures taken by U.S. Generating in taking environmental responsibility were outlined, among them its stated objective to investigate environmental impacts of any project prior to beginning of the project. To further illustrate its seriousness about environmental issues the company's standard have been set much higher than the minimum standards required by government. For example, an environmental training program was implemented as well as a recycling program. Contractors employed by the company must have and have to support a positive environmental philosophy. It was concluded that power companies could be successful in business, provided that they used the proper strategies while taking environmental responsibility

    Energy consumption in India is growing very rapidly. India.s own existing as well as any new discoveries of natural gas revenues may meet only a fraction of its growing demand for energy. Hence, it will become more dependent on the global market for the supply of gas. But it is always difficult for different nations to reach a bilateral agreement on joint projects such as gas pipelines. India has been importing natural gas mostly in the form of Liquefied Natural Gas (LNG). But for the last two decades, it has shown an increasing interest in importing gas from international market by a pipeline. For example, it has planned to import natural gas from Iran, Myanmar, Bangladesh, and Turkmenistan via a pipeline. But India.s best option is to purchase gas from its neighbor Bangladesh via a pipeline. Union Oil of California (Unocal), a large investor in Bangladeshi gas, has proposed to build a pipeline, to sell the gas from its Bibiyana field. A Bangladesh-India pipeline potentially offers several socio-economic benefits. But the project, however, so far has made a little progress. Political issues attached to the project. If the Bangladeshi pipeline plan fails, India will turn other alternative options to meet its gas demand. India already has entered into agreement with International consortiums for LNG purchase. Furthermore, the country is also keen on increasing its effort to develop non-conventional sources in the near future. If these alternatives become viable, India.s demand for and dependence on foreign natural gas will decrease and natural gas (of Bangladesh, for example) might lose some of its value. Keywords: Natural gas exploration and supply in India and Bangladesh, Bangladesh-to-India pipeline, Unocal, natural gas import, market, politics, LNG, non-conventional hydrocarbon sources.

  12. Gas turbine designer computer program - a study of using a computer for preliminary design of gas turbines

    Energy Technology Data Exchange (ETDEWEB)

    Petersson, Rickard

    1995-11-01

    This thesis presents calculation schemes and theories for preliminary design of the fan, high pressure compressor and turbine of a gas turbine. The calculations are presented step by step, making it easier to implement in other applications. The calculation schemes have been implemented as a subroutine in a thermodynamic program. The combination of the thermodynamic cycle calculation and the design calculation turned out to give quite relevant results, when predicting the geometry and performance of an existing aero engine. The program developed is able to handle several different gas turbines, including those in which the flow is split (i.e. turbofan engines). The design process is limited to the fan, compressor and turbine of the gas turbine, the rest of the components have not been considered. Output from the program are main geometry, presented both numerically and as a scale plot, component efficiencies, stresses in critical points and a simple prediction of turbine blade temperatures. 11 refs, 21 figs, 1 tab

    This project will provide a full demonstration of an entirely new package of exploration technologies that will result in the discovery and development of significant new gas reserves now trapped in unconventional low-permeability reservoirs. This demonstration includes the field application of these technologies, prospect definition and well siting, and a test of this new strategy through wildcat drilling. In addition this project includes a demonstration of a new stimulation technology that will improve completion success in these unconventional low permeability reservoirs which are sensitive to drilling and completion damage. The work includes two test wells to be drilled by Snyder Oil Company on the Shoshone/Arapahoe Tribal Lands in the Wind River Basin. This basin is a foreland basin whose petroleum systems include Paleozoic and Cretaceous source beds and reservoirs which were buried, folded by Laramide compressional folding, and subsequently uplifted asymmetrically. The anomalous pressure boundary is also asymmetric, following differential uplift trends

  15. Exploring Advanced Technology Gas Turbine Engine Design and Performance for the Large Civil Tiltrotor (LCTR)

    Science.gov (United States)

    Snyder, Christopher A.

    2014-01-01

    A Large Civil Tiltrotor (LCTR) conceptual design was developed as part of the NASA Heavy Lift Rotorcraft Systems Investigation in order to establish a consistent basis for evaluating the benefits of advanced technology for large tiltrotors. The concept has since evolved into the second-generation LCTR2, designed to carry 90 passengers for 1,000 nautical miles at 300 knots, with vertical takeoff and landing capability. This paper explores gas turbine component performance and cycle parameters to quantify performance gains possible for additional improvements in component and material performance beyond those identified in previous LCTR2 propulsion studies and to identify additional research areas. The vehicle-level characteristics from this advanced technology generation 2 propulsion architecture will help set performance levels as additional propulsion and power systems are conceived to meet ever-increasing requirements for mobility and comfort, while reducing energy use, cost, noise and emissions. The Large Civil Tiltrotor vehicle and mission will be discussed as a starting point for this effort. A few, relevant engine and component technology studies, including previous LCTR2 engine study results will be summarized to help orient the reader on gas turbine engine architecture, performance and limitations. Study assumptions and methodology used to explore engine design and performance, as well as assess vehicle sizing and mission performance will then be discussed. Individual performance for present and advanced engines, as well as engine performance effects on overall vehicle size and mission fuel usage, will be given. All results will be summarized to facilitate understanding the importance and interaction of various component and system performance on overall vehicle characteristics.

    Patil, Devendra; Song, Gangbing

    2016-04-01

    As offshore oil and gas exploration moves further offshore and into deeper waters to reach hydrocarbon reserves, it is becoming essential for the industry to develop more reliable and efficient hydraulic accumulators to supply pressured hydraulic fluid for various control and actuation operations, such as closing rams of blowout preventers and controlling subsea valves on the seafloor. By utilizing the shape memory effect property of nitinol, which is a type of shape memory alloy (SMA), an innovative SMA actuated hydraulic accumulator prototype has been developed and successfully tested at Smart Materials and Structure Laboratory at the University of Houston. Absence of gas in the developed SMA accumulator prototype makes it immune to hydrostatic head loss caused by water depth and thus reduces the number of accumulators required in deep water operations. Experiments with a feedback control have demonstrated that the proposed SMA actuated accumulator can provide precisely regulated pressurized fluids. Furthermore the potential use of ultracapacitors along with an embedded system to control the electric power supplied to SMA allows this accumulator to be an autonomous device for deployment. The developed SMA accumulator will make deepwater oil extraction systems more compact and cost effective.

  20. Joint exploration and development: A self-salvation road to sustainable development of unconventional oil and gas resources

    2017-11-01

    Full Text Available Commercial production of unconventional oil and gas resources will not be easily achieved without large-scale engineering measures, let alone the additional operation cost, increasingly stricter requirement for safety and environment, fluctuating low oil and gas prices, etc., defeating the confidence of those investors. Therefore, unconventional measures are urgently needed to guide the exploration and exploitation of unconventional oil and gas resources. Thus, we put forward the concept of joint exploration and development by integrating research methodologies and operating techniques for a variety of oil and gas resources to simultaneously achieve analysis, construction, gathering and exploitation of multiple hydrocarbon sources. In this way, the annoying interference between the produced mixture of hydrocarbon flow resulting in the reduction of single-well flowrate will be possibly turned into a dynamic mutual force to enhance the well's flowrate. We also point out that the inevitability of joint exploration and development is determined by the occurrence conditions of oil and gas resources, its feasibility relies on the advancement of technologies, and its arduous and long-term nature is attributed to the current energy market and environment. In spite of various problems and difficulties, we believe that joint exploration and development will be a feasible option to achieve both cost reduction and production & benefit enhancement, boost investors' confidence, raise energy comprehensive utilization, and enhance energy supply efficiency. In conclusion, the advantages of joint exploration and development outweigh its disadvantages for both countries and enterprises.

  1. The Expedited Remedial Action Program: A case study. The Alhambra Front Street manufactured gas plant site

    Padleschat, J.A.; McMahon, T.D.

    1996-12-31

    Early in 1995, the Department of Toxic Substances Control asked Southern California Gas Company (SoCalGas) to enter one of its manufactured gas plant (MGP) sites into the new Expedited Remedial Action Program (ERAP). SoCalGas initially was not enthusiastic about the new program. Nevertheless, SoCalGas submitted an application for its Alhambra MGP site to be selected for the ERAP. The Alhambra Site was accepted into ERAP in November 1995, and was the first ERAP site to have orphan shares. MGP sites are well suited to the ERAP. They often involve few potentially responsible parties and can be expected to have the same primary contaminants: polycyclic aromatic hydrocarbons (PAH), which are a byproduct of the gas manufacturing process, and petroleum hydrocarbons from the crude oil feedstock used to manufacture the gas.

    Full Text Available Deep drilling of marine sediments and igneous crust offers a unique opportunity to explore how life persists and evolves in the Earth’s deepest subsurface ecosystems. Resource availability deep beneath the seafloor may impose constraints on microbial growth and dispersal patterns that differ greatly from those in the surface world. Processes that mediate microbial evolution and diversity may also be very different in these habitats, which approach and probably passthe extreme limits of life. Communities in parts of the deep subsurface may resemble primordial microbial ecosystems, and may serve as analogues of life on other planetary bodies, such as Mars or Europa, that have or once had water.

    Rising global energy demands associated to unbalanced allocation of water resources highlight the importance of water management solutions for the gas industry. Advanced drilling, completion and stimulation techniques for gas extraction, allow more economical access to unconventional gas reserves. This stimulated a shale gas revolution, besides tight gas and coalbed methane, also causing escalating water handling challenges in order to avoid a major impact on the environment. Hydraulic fracturing allied to horizontal drilling is gaining higher relevance in the exploration of unconventional gas reserves, but a large amount of wastewater (known as "produced water") is generated. Its variable chemical composition and flow rates, together with more severe regulations and public concern, have promoted the development of solutions for the treatment and reuse of such produced water. This work intends to provide an overview on the exploration and subsequent environmental implications of unconventional gas sources, as well as the technologies for treatment of produced water, describing the main results and drawbacks, together with some cost estimates. In particular, the growing volumes of produced water from shale gas plays are creating an interesting market opportunity for water technology and service providers. Membrane-based technologies (membrane distillation, forward osmosis, membrane bioreactors and pervaporation) and advanced oxidation processes (ozonation, Fenton, photocatalysis) are claimed to be adequate treatment solutions.

    2017-12-01

    Full Text Available Wufeng-Longmaxi Formations shale gas is a new exploration field in Wuxi area, Sichuan Basin, China. Some geological parameters related to shale gas evaluation of the new exploration wells in Wuxi area have been studied, including shale reservoir, gas-bearing, geochemical and paleontological characteristics. The study suggests that the original shale gas generation conditions of the area were good, but later this area went through serious and multi-phase tectonic damage. The major evidences include that: the δ13C2 value of shale gas is obviously higher than that in areas with the same maturity, indicating the shale gas is mainly late kerogen cracking gas and high hydrocarbon expulsion efficiency; the porosity of shale in Wuxi area is very low because of strong tectonic movements and lack of retained oil in the shale; some shale cores near faults even show very weak metamorphic characteristics with intense cleavage, and the epidermis of graptolite fossils was pyrolyzed. The comprehensive study shows shale gas in Wuxi area has prospective resources, but the possibility to get scale commercial production in recent time is very low.

    1993-12-01

    DOE has established a Natural Gas Coordinating Committee to ensure that all natural gas programs are conducted with a single strategic focus and without unnecessary duplication. This group prepared the FY 1993 update of the DOE Natural Gas Strategic Plan and Multi-Year Crosscut Program Plan (FY 1993-1998), which was first produced a year ago as a ``working draft`` for industry comment. This revised version incorporates these external comments and the results and recommendations of such developments as Order No. 636 of the Federal Energy Regulatory Commission (FERC), the FERC/DOE Natural Gas Deliverability Task Force Report; the National Petroleum Council`s 1992 natural gas study, The Potential for Natural Gas in the United States; relevant provisions of the EPACT, and new policy guidance from the Clinton Administration. The overall goal of the Natural Gas RD&D Program is to improve the Nation`s ability to supply, store, transport, distribute, and utilize gas in an economically efficient and environmentally beneficial manner. In support of DOE`s missions are programs that will: improve the confidence in the continued availability of a long-term gas supply (Resource and Extraction Area); provide more cost-effective and competitive means to use natural gas in both new and existing markets (Utilization Area); develop improved and less costly means of delivering and storing gas (Delivery and Storage Area); and develop and ensure availability of low cost environmental compliance technology, and reduce regulatory barriers to efficient market operations by promoting coordinated, efficient, and innovative Federal and State regulations (Environmental/Regulatory Impact Area). Each program area has its own unique mission that contributes to the goals and mission of the overall Natural Gas Program.

    Anthropogenic disturbances in wetland ecosystems can alter the composition and structure of plant assemblages and affect system functions. Extensive oil and gas extraction has occurred in wetland habitats along the northern Gulf of Mexico coast since the early 1900s. Activities involved with three-dimensional (3D) seismic exploration for these resources cause various disturbances to vegetation and soils. We documented the impact of a 3D seismic survey in coastal marshes in Louisiana, USA, along transects established before exploration began. Two semi-impounded marshes dominated by Spartina patens were in the area surveyed. Vegetation, soil, and water physicochemical data were collected before the survey, about 6 weeks following its completion, and every 3 months thereafter for 2 years. Soil cores for seed bank emergence experiments were also collected. Maximum vegetation height at impact sites was reduced in both marshes 6 weeks following the survey. In one marsh, total vegetation cover was also reduced, and dead vegetation cover increased, at impact sites 6 weeks after the survey. These effects, however, did not persist 3 months later. No effects on soil or water properties were identified. The total number of seeds that germinated during greenhouse studies increased at impact sites 5 months following the survey in both marshes. Although some seed bank effects persisted 1 year, these effects were not reflected in standing vegetation. The marshes studied were therefore resilient to the impacts resulting from 3D seismic exploration because vegetation responses were short term in that they could not be identified a few months following survey completion.

    1995-01-01

    Flammable gases generated in radioactive liquids. Twenty-five high level radioactive liquid waste storage tanks located underground at the Hanford Site are on a Flammable Gas Watch List because they contain waste which tends to retain the gases generated in it until rather large quantities are available for sudden release to the tank head space; if a tank is full it has little dome space, and a flammable concentration of gases could be produced--even if the tank is ventilated. If the waste has no tendency to retain gas generated in it then a continual flammable gas concentration in the tank dome space is established by the gas production rate and the tank ventilation rate (or breathing rate for unventilated tanks); this is also a potential problem for Flammable Gas Watch List tanks, and perhaps other Hanford tanks too. All Flammable Gas Watch List tanks will be fitted with Standard Hydorgen Monitoring Systems so that their behavior can be observed. In some cases, such as tank 241-SY-101, the data gathered from such observations will indicate that tank conditions need to be mitigated so that gas release events are either eliminated or rendered harmless. For example, a mixer pump was installed in tank 241-SY-101; operating the pump stirs the waste, replacing the large gas release events with small releases of gas that are kept below twenty-five percent of the lower flammability limit by the ventilation system. The concentration of hydrogen measured in Hanford waste tanks is greater than that of any other flammable gas. Hydrogen levels measured with a Standard Hydrogen Monitoring System in excess of 0.6 volume percent will cause Westinghouse Hanford Company to consider actions which will decrease the amount of flammable gas in the tank

    In 2000 Chevron began a project to learn how to characterize the natural gas hydrate deposits in the deep water portion of the Gulf of Mexico (GOM). Chevron is an active explorer and operator in the Gulf of Mexico and is aware that natural gas hydrates need to be understood to operate safely in deep water. In August 2000 Chevron worked closely with the National Energy Technology Laboratory (NETL) of the United States Department of Energy (DOE) and held a workshop in Houston, Texas to define issues concerning the characterization of natural gas hydrate deposits. Specifically, the workshop was meant to clearly show where research, the development of new technologies, and new information sources would be of benefit to the DOE and to the oil and gas industry in defining issues and solving gas hydrate problems in deep water.

    Full Text Available Natural gas has an increasing role in Chinese energy transformation. We present a system dynamics model of the natural gas industry in China. A new system dynamics model for natural gas companies based on reserve exploration and well construction as well as investment dynamics is proposed. The contribution of the paper is to analyze the influence of technology, investment and policy factors on the natural gas industry. We found that the dynamics of the main variables, including gas policy, cost of investment, accounting depreciation and exploitation technology, are sensitive to the sustainable development of resources. The simulations and results presented here will be helpful for government to reform policies, and for upstream companies to make decisions.

    The objective of this project is for Babcock Contractors Inc. (BCI) to provide process designs, and gasifier retort design for a fuel gas demonstration plant for Erie Mining Company at Hoyt Lake, Minnesota. The fuel gas produced will be used to supplement natural gas and fuel oil for iron ore pellet induration. The fuel gas demonstration plant will consist of five stirred, two-stage fixed-bed gasifier retorts capable of handling caking and non-caking coals, and provisions for the installation of a sixth retort. The process and unit design has been based on operation with caking coals; however, the retorts have been designed for easy conversion to handle non-caking coals. The demonstration unit has been designed to provide for expansion to a commercial plant (described in Commercial Plant Package) in an economical manner.

    Research and development program for helium gas compressor aerodynamics was planned for the power conversion system of the Gas Turbine High Temperature Reactor (GTHTR300). The axial compressor with polytropic efficiency of 90% and surge margin more than 30% was designed with 3-dimensional aerodynamic design. Performance and surge margin of the helium gas compressor tends to be lower due to the higher boss ratio which makes the tip clearance wide relative to the blade height, as well as due to a larger number of stages. The compressor was designed on the basis of methods and data for the aerodynamic design of industrial open-cycle gas-turbine. To validate the design of the helium gas compressor of the GTHTR300, aerodynamic performance tests were planned, and a 1/3-scale, 4-stage compressor model was designed. In the tests, the performance data of the helium gas compressor model will be acquired by using helium gas as a working fluid. The maximum design pressure at the model inlet is 0.88 MPa, which allows the Reynolds number to be sufficiently high. The present study is entrusted from the Ministry of Education, Culture, Sports, Science and Technology of Japan. (author)

    NASA's experience with electrochemical sensors in a hand-held toxic gas monitor serves as a basis for the development of a fixed on-board instrument, the Contingency Gas Analyzer (CGA), for monitoring selected toxic combustion products as well as oxygen and carbon dioxide on the Orion Crew Exploration Vehicle (CEV). Oxygen and carbon dioxide are major components of the cabin environment and accurate measurement of these compounds is critical to maintaining a safe working environment for the crew. Fire or thermal degradation events may produce harmful levels of toxic products, including carbon monoxide (CO), hydrogen cyanide (HCN), and hydrogen chloride (HCl) in the environment. These three components, besides being toxic in their own right, can serve as surrogates for a panoply of hazardous combustion products. On orbit monitoring of these surrogates provides for crew health and safety by indicating the presence of toxic combustion products in the environment before, during and after combustion or thermal degradation events. Issues identified in previous NASA experiences mandate hardening the instrument and components to endure the mechanical and operational stresses of the CEV environment while maintaining high analytical fidelity. Specific functional challenges involve protecting the sensors from various anticipated events- such as rapid pressure changes, low cabin pressures, and extreme vibration/shock exposures- and extending the sensor lifetime and calibration periods far beyond the current state of the art to avoid the need for on-orbit calibration. This paper focuses on lessons learned from the earlier NASA hardware, current testing results, and engineering solutions to the identified problems. Of particular focus will be the means for protecting the sensors, addressing well known cross-sensitivity issues and the efficacy of a novel self monitoring mechanism for extending sensor calibration periods.

    A survey conducted in 1995 by the American Petroleum Institute (API) found that the U.S. exploration and production (E&P) segment of the oil and gas industry generated more than 149 million bbl of drilling wastes, almost 18 billion bbl of produced water, and 21 million bbl of associated wastes. The results of that survey, published in 2000, suggested that 3% of drilling wastes, less than 0.5% of produced water, and 15% of associated wastes are sent to offsite commercial facilities for disposal. Argonne National Laboratory (Argonne) collected information on commercial E&P waste disposal companies in different states in 1997. While the information is nearly a decade old, the report has proved useful. In 2005, Argonne began collecting current information to update and expand the data. This report describes the new 2005-2006 database and focuses on the availability of offsite commercial disposal companies, the prevailing disposal methods, and estimated disposal costs. The data were collected in two phases. In the first phase, state oil and gas regulatory officials in 31 states were contacted to determine whether their agency maintained a list of permitted commercial disposal companies dedicated to oil. In the second stage, individual commercial disposal companies were interviewed to determine disposal methods and costs. The availability of offsite commercial disposal companies and facilities falls into three categories. The states with high oil and gas production typically have a dedicated network of offsite commercial disposal companies and facilities in place. In other states, such an infrastructure does not exist and very often, commercial disposal companies focus on produced water services. About half of the states do not have any industry-specific offsite commercial disposal infrastructure. In those states, operators take their wastes to local municipal landfills if permitted or haul the wastes to other states. This report provides state-by-state summaries of the

    In the present study, the K-40, U-238, Ra-226, Pb-210, Ra-228 and Th-228 activity concentrations were measured in 64 samples of wastes generated from shale gas exploration in North-Eastern Poland. The measured samples consist of drill cuttings, solid phase of waste drilling muds, fracking fluids, return fracking fluids and waste proppants. The measured activity concentrations in solid samples vary in a wide range from 116 to around 1100 Bq/kg for K-40, from 14 to 393 Bq/kg for U-238, from 15 to 415 Bq/kg for Ra-226, from 12 to 391 Bq/kg for Pb-210, from a few Bq/kg to 516 Bq/kg for Ra-228 and from a few Bq/kg to 515 Bq/kg for Th-228. Excluding the waste proppants, the measured activity concentrations in solid samples oscillate around their worldwide average values in soil. In the case of the waste proppants, the activity concentrations of radionuclides from uranium and thorium decay series are significantly elevated and equal to several hundreds of Bq/kg but it is connected with the mineralogical composition of proppants. The significant enhancement of Ra-226 and Ra-228 activity concentrations after fracking process was observed in the case of return fracking fluids, but the radium isotopes content in these fluids is comparable with that in waste waters from copper and coal mines in Poland.

    Owing to its high protein secretion capacity, simple nutritional requirements, and GRAS (generally regarded as safe) status, Bacillus licheniformis is widely used as a host for the industrial production of enzymes, antibiotics, and peptides. However, as compared with its close relative Bacillus subtilis , little is known about the physiology and stress responses of B. licheniformis . To explore its temperature-stress metabolome, B. licheniformis strains ATCC 14580 and B186, with respective optimal growth temperatures of 42°C and 50°C, were cultured at 42°C, 50°C, and 60°C and their corresponding metabolic profiles were determined by gas chromatography/mass spectrometry and multivariate statistical analyses. It was found that with increased growth temperatures, the two B. licheniformis strains displayed elevated cellular levels of proline, glutamate, lysine, pentadecanoic acid, hexadecanoic acid, heptadecanoic acid, and octadecanoic acid, and decreased levels of glutamine and octadecenoic acid. Regulation of amino acid and fatty acid metabolism is likely to be associated with the evolution of protective biochemical mechanisms of B. licheniformis . Our results will help to optimize the industrial use of B. licheniformis and other important Bacillus species.

  4. Polar politics : sovereignty tussles over Arctic territory threaten to impede oil and gas exploration

    Competition to secure oil and gas leases is concerning scientists who believe that the exploitation of mineral resources in the Arctic will damage the region faster than climate change. Scientists in the region have noted that hydrogen sulphide induced by sulphur-oxidizing bacteria are now thriving within glaciers in the Arctic. Imperial Oil and ExxonMobil Canada recently purchased 205,000 hectares in the Beaufort Sea, and the purchase is seen as a harbinger of further development in the region. Disputes between Canada and the United States are now beginning to cause controversy in the region. Climatic change may mean that the region will be ice-free in 50 years. Climatic change will also result in the destabilization of permafrost and in rises in sea levels. Melting of permafrost could cause subsidence and further difficulties for exploration engineers. If Canada is not able to convince the United Nations that the Northwest Passage constitutes internal waters, the environmental impacts of Russian resource development could be profound. In addition, offshore boundaries between the Yukon and Alaska are interpreted differently by Canadians and Americans. It was suggested that discussions are needed to ensure Canada's role in the Arctic. 2 figs

    There is some concern that coal seam gas mining may affect health and wellbeing through changes in social determinants such as living and working conditions, local economy and the environment. The onward impact of these conditions on health and wellbeing is often not monitored to the same degree as direct environmental health impacts in the mining context, but merits attention. This study reports on the findings from a recurrent theme that emerged from analysis of the qualitative component of a comprehensive Health Needs Assessment (HNA) conducted in regional Queensland: that health and wellbeing of communities was reportedly affected by nearby coal seam gas (CSG) development beyond direct environmental impacts. Qualitative analysis was initially completed using the Framework Method to explore key themes from 11 focus group discussions, 19 in-depth interviews, and 45 key informant interviews with health and wellbeing service providers and community members. A key theme emerged from the analysis that forms the basis of this paper. This study is part of a larger comprehensive HNA involving qualitative and quantitative data collection to explore the health and wellbeing needs of three communities living in proximity to CSG development in regional Queensland, Australia. Communities faced social, economic and environmental impacts from the rapid growth of CSG development, which were perceived to have direct and indirect effects on individual lifestyle factors such as alcohol and drug abuse, family relationships, social capital and mental health; and community-level factors including social connectedness, civic engagement and trust. Outer regional communities discussed the effects of mining activity on the fabric of their town and community, whereas the inner regional community that had a longer history of industrial activity discussed the impacts on families and individual health and wellbeing.

    1991-01-01

    Since crude oil was first discovered in commercial quantities in the Country, in 1956, Nigerian oil and gas exploration and production activities have steadily increased as petroleum assumed strategic importance in the nation's economy. However, just as occurs in many parts of the world, crude oil and gas are found and produced in Nigeria sometimes in very hostile and unfavorable environments. The search for oil and gas takes explorers to the hot regions of the Northern parts of the country, the swamp jungle location of the Niger Delta, as well as offshore locations in the Atlantic Ocean. Each terrain, whether land, swamp or offshore, in deep or shallow waters, present unique health, safety and environmental implications and challenges to the operators, as well as, to the Government regulators. From a background of existing Nigerian Laws and operational experience, this paper details the programmes that have been put in place to guarantee a healthy workforce, ensure the safety of personnel and equipment, and protect the Nigerian environment during oil and gas exploration and production operations, as well as their documented effectiveness. The paper discusses the performance of the Petroleum Industry by analyzing the health, safety and environmental records available from 1956 - 1990. The records of major incidents related to safety and environment over the period are discussed and evaluated. The paper notes that relatively speaking, in spite of the Bomu 2 and Funiwa V oil well blow-outs in 1970 and 1980 respectively which caused extensive environmental damages and the Anieze, Oniku and KC 1 gas well blow-out of 1972, 1975 and 1989 respectively, which resulted in the loss of the rigs drilling the locations concerned, the safety performance records in the Nigerian oil and gas exploration and production activities in the past thirty-five years have been satisfactory compared with the records of similar operations in most other parts of the world

    Advanced geochemical soil gas methods have been successfully developed for the exploration of oil/gas/uranium and for environmental assessments. Application of these cost-effective technologies in India can substantially reduce exploration risk while accelerating the development of oil/gas/uranium onshore resources. A reliable and effective monitoring system using geochemical soil gas surveys ensures that CO 2 Enhanced Oil Recovery operations as well as CO 2 sequestration projects are safe and acceptable for the disposal of CO 2 , Soil gas surveys along with other technologies can also be applied for monitoring of oil/gas pipelines for leakage, especially those that are old or pass through populated regions

    The frustrations of environmental groups were expressed by a representative from the Canadian Parks and Wilderness Society. Emphasis was placed on the lack of support from the Alberta government to protect lands from industrial development. Some recent major conflict between the oil industry, the Alberta government, and environmentalists were chronicled. As an example, the government's Special Places 2000 program, which designates environmentally-sensitive areas in Alberta, was boycotted by environmental groups, because in the view of environmental groups, the policy failed to clearly designate protected areas. In 1993, environmental groups approached major oil and gas companies to establish an agreement on which lands were to be protected. As a result, the Eastern Slopes Environment and Energy Committee (ESEE) was formed, however, the Alberta government failed to support this initiative. The speaker recommended a greater degree of public involvement in decisions regarding access to lands for industrial development.More rigorous assessments at proposed development sites prior to industrial activity was also suggested. In the view of the speaker further conflict between environmental groups and the energy industry were inevitable, unless the industry took some responsibility in protecting environmentally-sensitive lands

    1981-01-01

    This paper considers the practical problem of applying economic analysis to designing minerals exploration and data collection strategies for developing countries. Formal decision rules for the design of government exploration and minerals-data-collection programs are derived by using a minerals-industry planning model that has been extended to include an exploration function. Rules derived are applicable to centrally planned minerals industries as well as market-oriented minerals sectors. They pertain to the spatial allocation of exploration effort and to the allocation of activities between government and private concerns for market-oriented economies. Programs characterized by uniform expenditures, uniform information coverage across regions, or uniform-density grid drilling progrmas are shown to be inferior to the strategy derived. Moreover, for market-oriented economies, the economically optimal mix in exploration activities between private and government data collection would require that only private firms assess local sites and that government agencies carry out regional surveys. ?? 1981.

    Created by Law 9.478/97 (Law of Oil), the Agencia Nacional do Petroleo, Gas Natural e Biocombustiveis (ANP) has, among others, the purpose of laborating edicts and promoting public tenders to give concession to exploration, development and production of oil and natural gas, celebrating the future contracts and monitoring its execution. This procedure, however, has strong differences in comparison to the classical law 8.666/93 - the general law of public tenders of Brazil -, given the specificities of petroleum and gas natural industry. Based on the mitigation of the concept of free competition, ANP made, recently, use of clauses that restrict the offers to the winning bidders that participate in ANP's public tenders. The restrictive measure taken by the Regulatory Agency is constitutional, in order that it, indeed, develops the market and prevents the concentration of a single agent in a particular economic exploratory block, accomplishing the real free competition.

    2005-01-01

    To accelerate the development of competition in gas markets, some European regulators (in United Kingdom or in France) have decided to implement gas release programs. These programs compel the incumbent to sell gas that is no longer sold to its customers to its competitors. A first intuition would suggest that such a measure could give the incumbent an incentive to let its own costs rise in order to raise its rival's ones. With a duo-poly model, we found some cases where incentives to raise costs do exist but, in most of the cases there is no such incentives. (authors)

    Due to the increasing importance of natural gas for modern economic activity, and gas's non-renewable nature, it is extremely important to try to estimate possible trajectories of future natural gas production while considering uncertainties in resource estimates, demand growth, production growth and other factors that might limit production. In this study, we develop future scenarios for natural gas supply using the ACEGES computational laboratory. Conditionally on the currently estimated ultimate recoverable resources, the ‘Collective View’ and ‘Golden Age’ Scenarios suggest that the supply of natural gas is likely to meet the increasing demand for natural gas until at least 2035. The ‘Golden Age’ Scenario suggests significant ‘jumps’ of natural gas production – important for testing the resilience of long-term strategies. - Highlights: • We present the ‘Collective View’ and ‘Golden Age’ Scenarios for natural gas production. • We do not observe any significant supply demand pressure of natural gas until 2035. • We do observe ‘jumps’ in natural gas supply until 2035. • The ACEGES-based scenarios can assess the resilience of longterm strategies

The working environment is directly in contact with toxic materials would be very harmful to the human body when exposed continuously. An environment or factory containing toxic gases as an example of CO, SO or LPG gas in certain concentrations can cause eye irritation or shortness of breath. Therefore we need an early warning system that can measure the concentration of these gases and may give a warning to workers associated with the concentration of the gas to the workers. The early warning system was made using three gas sensors, three heat sensors, LEDs and buzzer. Recitation and processing of the sensor is processed by a 16 bit microcontroller which will condition the room. In making such a system is used programmable fuzzy algorithms previously simulated with MATLAB, C Programming used as logic programming refers to the simulation results, miniature rooms created with three main space for workers in a hallway and an emergency exit. The results of such a system is in a room when the detected gas concentration exceeds the threshold, the system will activate the buzzer and will activated LED as the safest evacuation route directions.

    2009-12-31

    This research relates to improving the efficiency of flow in a turbine exhaust, and thus, that of the turbine and power plant. The Phase I SBIR project demonstrated the technical viability of “strutlets” to control stalls on a model diffuser strut. Strutlets are a novel flow-improving vane concept intended to improve the efficiency of flow in turbine exhausts. Strutlets can help reduce turbine back pressure, and incrementally improve turbine efficiency, increase power, and reduce greenhouse gas emmission. The long-term goal is a 0.5 percent improvement of each item, averaged over the US gas turbine fleet. The strutlets were tested in a physical scale model of a gas turbine exhaust diffuser. The test flow passage is a straight, annular diffuser with three sets of struts. At the end of Phase 1, the ability of strutlets to keep flow attached to struts was demonstrated, but the strutlet drag was too high for a net efficiency advantage. An independently sponsored followup project did develop a highly-modified low-drag strutlet. In combination with other flow improving vanes, complicance to the stated goals was demonstrated for for simple cycle power plants, and to most of the goals for combined cycle power plants using this particular exhaust geometry. Importantly, low frequency diffuser noise was reduced by 5 dB or more, compared to the baseline. Appolicability to other diffuser geometries is yet to be demonstrated.

    The Interstellar Boundary Explorer mission includes a comprehensive Education and Public Outreach (EPO) program in heliophysics that is overseen and implemented by the Adler Planetarium and evaluated by Technology for Learning Consortium, Inc. Several components of the IBEX EPO program were developed during the prime phase of the mission that were specifically designed for use in informal institutions, especially museums and planetaria. The program included a widely distributed planetarium show with accompanying informal education activities, printed posters, lithographs and other resources, funding for the development of the GEMS Space Science Sequence for Grades 6-8 curriculum materials, development of the IBEX mission website, development of materials for people with special needs, participation in the Heliophysics Educator Ambassador program, and support for the Space Explorers Afterschool Science Club for Chicago Public Schools. In this paper, we present an overview of the IBEX EPO program summative evaluation techniques and results for 2008 through 2012.

  9. Oil and gas exploration and production activities in Brazil: The consideration of environmental issues in the bidding rounds promoted by the National Petroleum Agency

    International Nuclear Information System (INIS)

    Mariano, Jacqueline; La Rovere, Emilio

    2007-01-01

    This paper aims to address and analyze the environmental issues related to the Brazilian bidding rounds for exploration and production of oil and natural gas held by the National Petroleum Agency (ANP) from 1999 to 2005. To do so, after a brief retrospective of the seven rounds, the four main points of the bidding process are analyzed from an environmental perspective: the selection criteria for choosing the areas to be offered, the Minimum Exploration Program required by ANP, the eligibility criteria for the oil companies to take part of the bids and the concession agreements. Thus, it is possible to present the evolution of the environmental component insertion from the first to the seventh bidding round, and then to assess its efficiency in each round, apart from offering suggestions for its improvement. The suggestions presented are based on the related international experience and on the lessons learned during the last seven years

  10. Gas supply for independent power projects: Drilling programs and reserve acquisitions

    International Nuclear Information System (INIS)

    Lambert, J.D.; Walker, R.K.

    1990-01-01

    Developers of gas-fired independent power projects, although drawn to gas as the fuel of choice for economic and environmental reasons, are finding the problem of cost-effective gas supply to be intractable. By one estimate, there are $6 billion worth of gas-fired projects languishing in the planning stage for want of long-term gas supply that is acceptable to project lenders. Worse still, as the authors are aware, some currently operating gas-fired projects lack such a supply, thus forcing the developer to rely on the spot market for gas as an interim (and unsatisfactory) solution. Although spot market prices in the deregulated natural gas industry have remained relatively low over several years, long-term gas supply has become problematic, particularly for power projects whose economics typically require an assured supply at a determined price over a multiyear period. In short, while there is an increasing demand for gas as a preferred source of fuel supply for power projects, there are discontinuities in the approaches taken to contracting for that supply by producers and developers. These concern primarily allocation of the risk of commodity-driven price increases during the term of the fuel supply contract. Without a means of accommodating price-related risk, the parties will inevitably find themselves at an impasse in contract negotiations. If there is a barrier to the independent power generation industry's vertical integration into gas production, it is the fundamental insularity of the two industries. As they have discovered, it may be indispensable for gas producers and power developers to employ intermediaries familiar with both industries in order to consummate appropriate joint-venture drilling programs and reserve acquisitions. Given the economic consequences of doing so successfully, however, they believe such programs and acquisitions may become an integral part of independent power developers' business strategy in the 1990s and beyond

  12. U. S. EPA voluntary programs and the oil and gas industry : Natural Gas STAR and Energy STAR Buildings Partnership

    International Nuclear Information System (INIS)

    Gunnung, P.

    2000-01-01

    The structure of two EPA programs directed towards wasted energy in buildings, reducing emissions, increasing energy efficiency and maximizing profits are described. The programs are based on a partnership approach between EPA and participants, and involve elements of plans and performance benchmarks, an integrated approach and communications and demonstration of successful initiatives. EPA provides planning and technical support in the form of a website, software tools, manuals, electronic sources and a purchasing tool kit. The Energy STAR Building Partnership has over 3,000 participants, and can boast of a cumulative saving of over $ 1.4 billion in energy bills and carbon dioxide emission reduction of 44.1 billion pounds, resulting from efficiency upgrades. The Natural Gas Partnership between the EPA and the oil and natural gas industry to cost effectively reduce methane emissions from the production, transmission, and distribution of natural gas also has had a number of successful initiatives such as replacement or retrofit of high bleed pneumatic devices, installation of flash tank separators on glycol dehydrators and other partner-reported projects such as replacement of wet seals with dry seals on compressors and connecting glycol pump to vapour recovery unit. As a results of these and other initiatives, annual methane emission was reduced by 22.2 bcf in 1998 as opposed to 3.4 bcf prior to the beginning of the program in 1993. Approximately 67 per cent of all reductions can be attributed to partner innovation. Overall assessment is that the program is innovative, achieves both economic and environmental goals, facilitates government and industry cooperation and is living proof that non-regulatory, cooperative programs work

    Gorbunov, P. A.; Vorobyov, S. V.

    2017-10-01

    In the paper the features of reservoir pressures changes in the northern part of West Siberian oil-and gas province are described. This research is based on the results of hydrodynamic studies in prospecting and explorating wells in Yamal-Nenets Autonomous District. In the Cenomanian, Albian, Aptian and in the top of Neocomian deposits, according to the research, reservoir pressure is usually equal to hydrostatic pressure. At the bottom of the Neocomian and Jurassic deposits zones with abnormally high reservoir pressures (AHRP) are distinguished within Gydan and Yamal Peninsula and in the Nadym-Pur-Taz interfluve. Authors performed the unique zoning of the territory of the Yamal-Nenets Autonomous District according to the patterns of changes of reservoir pressures in the section of the sedimentary cover. The performed zoning and structural modeling allow authors to create a set of the initial reservoir pressures maps for the main oil and gas bearing complexes of the northern part of West Siberia. The results of the survey should improve the efficiency of exploration drilling by preventing complications and accidents during this operation in zones with abnormally high reservoir pressures. In addition, the results of the study can be used to estimate gas resources within prospective areas of Yamal-Nenets Autonomous District.

    The possibility of using complex information on morphological parameters of structures, block porosity and the reservoir pressure gradient over previously explored deposits for the development of a multidimensional equation for estimating secondary porosity is considered. This is examined by the example of reservoirs with secondary (fractured) porosity of the Upper Cretaceous carbonate deposits of the Tersko-Sunzhenskaya oil and gas bearing region of the Ciscaucasia. The use of this equation makes it possible to predict the magnitude of the secondary porosity on the anticlinal structures, which are newly discovered by seismic methods at a later stage of exploration in the relevant oil and gas region, as a quantitative criterion that predicts the presence of a trap.

    Full Text Available Pakistan's Maternal, Newborn and Child Health (MNCH Program is faced with multiple challenges in service delivery, financial and logistic management, training and deployment of human resources, and integration within the existing health system. There is a lack of evidence on managerial aspects of the MNCH program management and implementation.This study used qualitative methods to explore the challenges national, provincial and district program managers have faced in implementing a community midwifery program in province of Punjab while also exploring future directions for the program under a devolved health system. While the program had been designed in earnest, the planning lacked critical elements of involving relevant stakeholders in design and implementation, socio-demographic context and capacity of the existing health system. Financial limitations, weak leadership and lack of a political commitment to the problem of maternal health have also had an impact on program implementation.Our study results suggest that there is a need to re-structure the program while ensuring sustainability and collaboration within the health sector to increase uptake of skilled birth attendance and improve maternal health care in Pakistan.

    Natural Resources Canada manages the Program of Energy Research and Development (PERD), which covers all but a few of non-nuclear energy areas. The aim of the Program is to focus on research and technology developments that support a dynamic and diversified energy supply, while encouraging industries to consume the energy efficiently. Twelve federal departments and agencies are stakeholders in energy research and development and the 57 million dollar annual budget is allocated amongst the stakeholders according to the priorities established. Each year, one-quarter of the program is evaluated externally and potential reallocation examined, a recent initiative implemented as part of a results-based management (RBM) system. Five federal departments and one agency carry out offshore research and development activities, touching the fields of basin assessment and geotechnics in the Canadian North and offshore East Coast, winds-wave-current modelling, the management of sea ice, iceberg and ice-structure interactions, ship design and navigation issues. In this last category, activities related to offshore safety, management of offshore drilling and production wastes, oil spills remediation, and assessment of cumulative effects of wastes and produced waters are included. These activities are detailed in the presentation, and the author discussed the future shifts likely to occur in PERD so that the needs of the regulatory agencies in terms of science and technology are met. There is also the aspect of the protection of the interests of the Canadian public to consider. 1 tab.

  6. Evolution and development of a deliverability improvement program for gas storage

    International Nuclear Information System (INIS)

    Maddox, T.D.; Sikorski, D.L.

    1994-01-01

    With the implementation in November 1993 of FERC Order 636, the responsibilities and contractual obligations for a Gas Transmission Company operating Gas Storage have changed. Among these responsibilities is the ability to deliver gas from storage in a timely manner as specified by gas storage contracts. To ensure that their deliverability obligations are met, a program has been implemented to review well performance and to re-work wells where deliverability can economically be improved. This program is aimed at maintaining or improving deliverability from wells and monitoring their future performance. Re-working existing wells has proven to be an economically successful method of maintaining deliverability compared to drilling new wells to meet this purpose. Re-working can be broken into two groups of wells: wells that have mechanical problems that need to be corrected or wells that need some type of stimulation treatment. In developing a rework program, several things need to be addressed such as: a candidate recognition program, the design of the work to be performed, execution of that work, and the evaluation of the results obtained along with the economics. The Deliverability Improvement Program is in its third year. It has developed from a small pilot program to a substantial part of normal storage activities. The purpose of this paper is to review the processes used to find candidates to work on and an evaluation of work performed

    1982-05-01

    A combination of technical, economic, political, and environmental constraints hamper industry's ability to use natural gas efficiently. Although the industrial sector has the best potential to absorb the current surplus of natural gas, many industrial users are disenchanged with the high cost, low efficiency, and environmental problems associated with the existing inventory of gas-fired process systems. Consequently, it is essential for an organization like Gas Research Institute (GRI), which has a national scope and a mandate to generate energy end-use benefits for the industrial gas consumer, to assume a leadership role in the development program aimed, not only at upgrading the energy efficiency of industrial process equipment, but at increasing its production capability while meeting environmental standards.

    2014-09-01

    Oil and natural gas exploration and production (E&P) activities generate emissions from diesel engines, compressor stations, condensate tanks, leaks and venting of natural gas, construction of well pads, and well access roads that can negatively impact air quality on both local and regional scales. A mobile, autonomous air quality monitoring laboratory was constructed to collect measurements of ambient concentrations of pollutants associated with oil and natural gas E&P activities. This air-monitoring laboratory was deployed to the Allegheny National Forest (ANF) in northwestern Pennsylvania for a campaign that resulted in the collection of approximately 7 months of data split between three monitoring locations between July 2010 and June 2011. The three monitoring locations were the Kane Experimental Forest (KEF) area in Elk County, which is downwind of the Sackett oilfield; the Bradford Ranger Station (BRS) in McKean County, which is downwind of a large area of historic oil and gas productivity; and the U.S. Forest Service Hearts Content campground (HC) in Warren County, which is in an area relatively unimpacted by oil and gas development and which therefore yielded background pollutant concentrations in the ANF. Concentrations of criteria pollutants ozone and NO2 did not vary significantly from site to site; averages were below National Ambient Air Quality Standards. Concentrations of volatile organic compounds (VOCs) associated with oil and natural gas (ethane, propane, butane, pentane) were highly correlated. Applying the conditional probability function (CPF) to the ethane data yielded most probable directions of the sources that were coincident with known location of existing wells and activity. Differences between the two impacted and one background site were difficult to discern, suggesting the that the monitoring laboratory was a great enough distance downwind of active areas to allow for sufficient dispersion with background air such that the localized

    2006-10-01

    Full Text Available Gas hydrates - the firm crystal connections form water (liquid water, ice, water vapor and low-molecular waterproof natural gases (mainly methane whose crystal structure effectively compresses gas e.s.: each cubic meter of hydrate can yield over 160 m3 of methane.In present time, the exploitation of the Messoyahsk (Russia and Mallik (Canada deposits of gas hydrates is conducted actively. The further perfection of prospecting methods in the field of studying gas hydrates containing sediments depends on the improvement of geophysical and the well test research, among which native-state core drilling is one of the major. Sampling a native-state core from gas hydrates sediments keeps not only the original composition but structural - textural features of their construction.Despite of the appeal to use gas hydrates as a perspective and ecologically pure fuel possessing huge resources, the investigation and development of their deposits can lead to a number of negative consequences connected with hazards arising from the maintenance of their technical and ecological safety of carrying out. Scales of the arising problems can change from local to regional and even global.

  11. Explorer-II: Wireless Self-Powered Visual and NDE Robotic Inspection System for Live Gas Distribution Mains

    2008-09-30

    Carnegie Mellon University (CMU) under contract from Department of Energy/National Energy Technology Laboratory (DoE/NETL) and co-funding from the Northeast Gas Association (NGA), has completed the overall system design, field-trial and Magnetic Flux Leakage (MFL) sensor evaluation program for the next-generation Explorer-II (X-II) live gas main Non-destructive Evaluation (NDE) and visual inspection robot platform. The design is based on the Explorer-I prototype which was built and field-tested under a prior (also DoE- and NGA co-funded) program, and served as the validation that self-powered robots under wireless control could access and navigate live natural gas distribution mains. The X-II system design ({approx}8 ft. and 66 lbs.) was heavily based on the X-I design, yet was substantially expanded to allow the addition of NDE sensor systems (while retaining its visual inspection capability), making it a modular system, and expanding its ability to operate at pressures up to 750 psig (high-pressure and unpiggable steel-pipe distribution mains). A new electronics architecture and on-board software kernel were added to again improve system performance. A locating sonde system was integrated to allow for absolute position-referencing during inspection (coupled with external differential GPS) and emergency-locating. The power system was upgraded to utilize lithium-based battery-cells for an increase in mission-time. The resulting robot-train system with CAD renderings of the individual modules. The system architecture now relies on a dual set of end camera-modules to house the 32-bit processors (Single-Board Computer or SBC) as well as the imaging and wireless (off-board) and CAN-based (on-board) communication hardware and software systems (as well as the sonde-coil and -electronics).

  4. Synthesis gas demonstration plant program, Phase I. Site confirmation report

    Energy Technology Data Exchange (ETDEWEB)

    1978-12-01

    With few reservations, the Baskett, Kentucky site exhibits the necessary characteristics to suggest compatibility with the proposed Synthesis Gas Demonstration Plant Project. An evaluation of a broad range of technical disciplinary criteria in consideration of presently available information indicated generally favorable conditions or, at least, conditions which could be feasibly accommodated in project design. The proximity of the Baskett site to market areas and sources of raw materials as well as a variety of transportation facilities suggests an overall favorable impact on Project economic feasibility. Two aspects of environmental engineering, however, have been identified as areas where the completion or continuation of current studies are required before removing all conditions on site suitability. The first aspect involves the current contradictory status of existing land use and planning ordinances in the site area. Additional investigation of the legality of, and local attitudes toward, these present plans is warranted. Secondly, terrestrial and aquatic surveys of plant and animal life species in the site area must be completed on a seasonal basis to confirm the preliminary conclusion that no exclusionary conditions exist.

  5. Analysis of selected energy security issues related to US crude oil and natural gas exploration, development, production, transportation and processing

    In July 1989, President Bush directed the Secretary of Energy to initiate the development of a comprehensive National Energy Strategy (NES) built upon a national consensus. The overall principle for the NES, as defined by the President and articulated by the Economic Policy Council (EPC), is the continuation of the successful policy of market reliance, consistent with the following goals: Balancing of energy, economic, and environmental concerns; and reduced dependence by the US and its friends and allies on potentially unreliable energy suppliers. The analyses presented in this report draw upon a large body of work previously conducted for DOE/Office of Fossil Energy, the US Department of Interior/Minerals Management Service (DOI/MMS), and the Gas Research Institute (GRI), referenced throughout the text of this report. This work includes assessments in the following areas: the potential of advanced oil and gas extraction technologies as improved through R ampersand D, along with the successful transfer of these technologies to the domestic petroleum industry; the economic and energy impacts of environmental regulations on domestic oil and gas exploration, production, and transportation; the potential of tax incentives to stimulate domestic oil and gas development and production; the potential environmental costs associated with various options for leasing for US oil and gas resources in the Outer Continental Shelf (OCS); and the economic impacts of environmental regulations affecting domestic crude oil refining

    Methane-oxidizing bacteria (MOB), a unique group of Gram-negative bacteria utilizing methane as a sole source of carbon and energy, have been proved to be a biological indicator for gas prospecting. Field and cultivation-free detection of MOB is important but still challenging in current microbial prospecting of oil and gas (MPOG) system. Herein, SERS was used for the first time to our knowledge to investigate two species of methanotrophs and four closely relevant bacteria that universally coexisted in the upper soil of natural gas. A special but very simple approach was utilized to make silver nanoparticles (Ag NPs) sufficiently contact with every single bacterial cell, and highly strong and distinct Raman signals free from any native fluorescence have been obtained, and successfully utilized for distinguishing MOB from other species. A more convincing multi-Raman criterion based on single Raman bands, and further the entire Raman spectrum in combination with statistical analysis (e.g., principal component analysis (PCA)), which were found capable of classifying MOB related bacterial cells in soil with an accuracy of 100%. This study therefore demonstrated sensitive and rapid SERS measurement technique accompanied by complete Raman database of various gas reservoirs related bacteria could aid field exploration of natural gas reservoir.

    The objective of this article is to evaluate the coverage and the economic impact of the Federal Government Program Aid Gas (Auxilio Gas) , started in the year of 2002. The evaluation covers only the state of Sao Paulo, using as source the Research of Familiar Budgets of IBGE 2002/2003. To evaluate the coverage of 'Aid-Gas' the targeted population is compared with the population that effectively received the benefit. To evaluate the economic impact of the program a test of significance of dummy variable that differentiate weight gas consumption on income for those attended by the program, controlled by Working-Leser function that models the covariates of gas expenses. A low coverage of the program was evidenced, only 32,098 families had received the benefit (4,01%) out of 786.929 families targeted group, those with per capita income was inferior the half minimum wage. The economic impact had mixed results. In one hand program beneficiaries would spend a larger percentage of income with gas consumption than those not reached; on the other hand, they would have access larger quantities of the product. If the food consumption and the gas consumption are correlated, and the families not benefited by the program are rationed, it is possible to confirm that the introduction of the program would increase welfare of families.

    2008-12-01

    During the winters of 2007 and 2008 the Japan Oil, Gas and Metals National Corporation (JOGMEC) and Natural Resources Canada (NRCan), with Aurora Research Institute as the operator, carried out an on-shore gas hydrate production test program at the Mallik site, Mackenzie Delta, Northwest Territories, Canada. The prime objective of the program was to verify the feasibility of depressurization technique by drawing down the formation pressure across a 12m perforated gas hydrate bearing section. This project was the second full scale production test at this site following the 2002 Japex/JNOC/GSC et al Mallik research program in which seven participants organizatinos from five countries undertook a thermal test using hot water circulation Field work in 2007 was devoted to establishing a production test well, installing monitoring devices outside of casing, conducting base line geophysical studies and undertaking a short test to gain practical experience prior to longer term testing planned for 2008 . Hydrate-dissociated gas was produced to surface by depressurization achieved by lowering the fluid level with a dowhole pump. However, the operation was terminated 60 hours after the start of the pumping mainly due to sand production problems. In spite of the short period (12.5 hours of ellapsed pumping time), at least 830m3 of the gas was produced and accumulated in the borehole. Sand screens were installed across the perforated interval at the bottom hole for the 2008 program to overcome operational problems encountered in 2007 and achieve sustainable gas production. Stable bottom hole flowing pressures were successfully achieved during a 6 day test with continuous pump operation. Sustained gas production was achieved with rates between 2000- 4000m3/day and cummulative gas volume in the surface of approximately 13,000m3. Temperature and pressure data measured at the bottom hole and gas and water production rates gave positive evidence for the high efficiency of gas

    2013-01-01

    NASA is developing new portable life support system (PLSS) technologies, which it is demonstrating in an unmanned ground based prototype unit called PLSS 2.0. One set of technologies within the PLSS provides suitable ventilation to an astronaut while on an EVA. A new component within the ventilation gas loop is a liquid-to-gas heat exchanger to transfer excess heat from the gas to the thermal control system s liquid coolant loop. A unique bench top prototype heat exchanger was built and tested for use in PLSS 2.0. The heat exchanger was designed as a counter-flow, compact plate fin type using stainless steel. Its design was based on previous compact heat exchangers manufactured by United Technologies Aerospace Systems (UTAS), but was half the size of any previous heat exchanger model and one third the size of previous liquid-to-gas heat exchangers. The prototype heat exchanger was less than 40 cubic inches and weighed 2.57 lb. Performance of the heat exchanger met the requirements and the model predictions. The water side and gas side pressure drops were less 0.8 psid and 0.5 inches of water, respectively, and an effectiveness of 94% was measured at the nominal air side pressure of 4.1 psia.

    1973-08-01

    A computer program for the thermodynamic modeling of singlecycle gas turbine plants is described. A high-temperature reactor is assumed as a heat source in the program, but the HTR can be replaced with another heat source without difficulty. Starting from a set of independent data, the program calculates efficiencies and mass flows. It indicates all values for a heat and power balance and prints out the temperatures and pressures for the different parts of the cycle. Besides this, the program is able to optimize the compression ratios for minimal power input. It also takes into account turbine rotor cooling (at the roots of the blades). Furthermore, the program is able to use either total pressure loss or specified losses in different parts of the cycle. The program GESlT can also handle systems with one or two intercoolers, or with no intercooler. GESIT gives all input and output values for the heat exchangers and turbo-machines. First the single-cycle gas turbine plant is described. After that the computational basis for the program and the program structure is explained. Instructions for data input are given so that the program can be immediately utilized. An example of input data together with the associated output is presented. (auth)

    1999-07-01

    Approximately one year ago, OSU-Okmulgee and the Gas Processors Association began discussions about the possibility of developing a natural Gas Technician Training Program for GPA members. Following a presentation to the Membership and Services Committee, Chairman John Ehlers solicited and obtained the approval of the GPA Executive Committee to sponsor the program. Participation in the program was also made available to GPSA members. The purpose of the program is to upgrade the technical competency and professional level of incoming natural gas compression technicians. It educates students to analytically diagnose, service and maintain gas compression equipment and systems using industry recommended procedures, special tools and service information. It also provides course content, which will enable successful graduates to advance in position after additional experience, and to understand new systems, technologies and components as they are introduced. The two-year Associate-In-Applied Science Degree program includes six successive college semesters. Nearly one-half of the time is designated for technical/academic education at Oklahoma State University-Okmulgee with the balance of time allocated for on-the-job internship experiences at sponsoring GPA/GPSA members. Each block of technical education and general education course work is followed by an immediate work experience time period designated to reinforce the technical and general education. These time periods are approximately seven and one-half weeks in length each. It is essential for the success of the students and the program that the students' education at OSU-Okmulgee and work experiences at GPA/GPSA member facilities be closely aligned for maximum student learning and retention. In addition to technical classes on gas compression equipment and components, the courses offered in math, speech, technical writing, psychology and ethics for example, prepare students to be able to communicate well, get

    Full Text Available Dans le cadre de la recherche des stockages souterrains de gaz, le Département Réservoirs Souterrains de Gaz de France est amené à établir un programme d'exploration destiné à sélectionner définitivement, et au moindre coût, les structures capables de satisfaire la demande. Cette sélection passe par une estimation des probabilités de rejet ou d'abandon affectant les différentes structures susceptibles de donner lieu à une exploration. Il faut ensuite constituer le programme d'exploration de chacun des sites retenus après cet examen; ce programme consiste en une liste d'opérations (forage, sismique, essai hydraulique, forage à faible profondeur etc. qui mettront le plus vite possible en évidence : - d'une part les défauts; - d'autre part les principales caractéristiques techniques de la structure étudiée. La règle est d'atteindre la décision sur la faisabilité du site au stockage avec le moindre coût d'exploration. Pour ce faire, une analyse détaillée des causes potentielles d'abandon (recensement des défauts permet de choisir les opérations à effectuer, et d'associer à chacun des défauts recensés, l'opération ou l'ensemble d'opérations permettant de le détecter de façon certaine. Alors les estimateurs économiques tels que l'espérance de dépense, le risque financier, l'espérance de gain, sont calculés pour chacun des programmes, en vue de déterminer l'ordre d'exécution optimal des opérations. L'intérêt d'une telle approche, en ce qui concerne la réduction des dépenses d'exploration, est illustré par un exemple. As part of its work concerning the search for underground gas storage sites, the Underground Storage Department of Gaz de France has established an exploration program for the definitive and lowcost selection of suitable geological structures. This selection involves estimating probabilities of rejecting or abandoning different structures liable to be targets for exploration. The

    In many respects, the EU is a strong player on the world stage, for example, in trade, climate change issues and crisis management. In its relationship with Russia over gas supply, however, the EU's political capacity remains limited. Part of the problem lies in the lack of EU unity, but this is more a symptom than an actual cause. A key explanation is the interplay between external and internal factors. The external factors - that is the EU's and Russia's conflicting interests and the structure of the political system - reinforce the EU's internal problems. This is an effect of that the gas issue falls under different policy areas (energy, foreign relations and security policy) within which the European Commission and the member states have different responsibilities. Another problem is that energy is the Commission's responsibility, but the real competence lies with the member states. The current multipolar structure of European politics reduces the scope for cooperation that favours the EU as a whole - in this case its energy security. The fact that the Commission and member states, and the member states among themselves, have different views on energy policy vis-a-vis Russia exacerbates these circumstances. Other key factors are the lack of transparency and competition in the gas sector (which suits both the Russian company Gazprom and large EU companies) and the unbalanced dependence of EU countries on Russian gas. Relations between France, Germany and Russia are also important. Germany and France are key players for the EU's energy security, and their support for the gas pipeline Nord Stream, their resistance to unbundling in the gas sector and their relatively warm relations with Russia have not strengthened the EU's position in its gas relationship with Russia. Besides, the Lisbon Treaty increases France's and Germany's powers inside the EU. Combined with the conflicting interests of the EU nd Russia, the

    Full Text Available Helium in China highly depends on import at present, so the most practical way to change the situation is searching for medium-to-large natural gas fields with high helium content. Therefore, the hydrocarbon accumulation mechanism and the helium origin of the Weiyuan high-helium natural gas reservoir have been analyzed to find out the feasibility of finding natural gas field with high helium content in the Presinian strata of the Sichuan Basin. Based on twelve outcrop sections and drilling data of four wells encountering the Presinian strata, the petrological features, sedimentary facies and source rocks of Presinian strata were systematically analyzed, which shows that the sedimentary formation developed in the Presinian is the Nanhua system, and the stratigraphic sequence revealed by outcrop section in the eastern margin includes the Nantuo, Datangpo, Gucheng and Liantuo Fms, and it is inferred that the same stratigraphic sequence may occur inside the basin. The Nantuo, Gucheng and Liantuo Fms are mainly glacial deposits of glutenite interbedded with mudstone; the Datangpo Fm is interglacial deposits of sandstone and shale, the lower part shale, rich in organic matter, is fairly good source rock. Further study showed that the Nantuo coarse-grained clastic reservoir, Datangpo source rock and the intruded granite “helium source rock” make up a good high-helium gas system. Controlled by the early rift, the thick Presinian sedimentary rocks occur primarily inside the rift. The distribution of sedimentary rocks and granite in the basin was predicted by use of the seismic data, which shows that the feasibility of finding high-helium gas reservoirs in Ziyang area of the Sichuan Basin is great.

    This paper summarizes the Next Generation Natural Gas Vehicle (NG-NGV) Program that is led by the U.S. Department Of Energy's (DOE's) Office of Heavy Vehicle Technologies (OHVT) through the National Renewable Energy Laboratory (NREL). The goal of this program is to develop and implement one Class 3-6 compressed natural gas (CNG) prototype vehicle and one Class 7-8 liquefied natural gas (LNG) prototype vehicle in the 2004 to 2007 timeframe. OHVT intends for these vehicles to have 0.5 g/bhp-hr or lower emissions of oxides of nitrogen (NOx) by 2004 and 0.2 g/bhp-hr or lower NOx by 2007. These vehicles will also have particulate matter (PM) emissions of 0.01 g/bhp-hr or lower by 2004. In addition to ambitious emissions goals, these vehicles will target life-cycle economics that are compatible with their conventionally fueled counterparts

  18. Risk measurement for oil and gas exploration: the marriage of geological and financial techniques

    Stauffer, T.

    2002-09-01

    A method is presented for fully risking projects, such as exploration ventures or the acquisition of undeveloped reserves. The expected value of an exploration project overstates the 'value', because it does not reflect the uncertainty in the project, as measured by its variance or standard deviation. if the expected value is calculable, then the risk-adjusted value (RAV) can also be calculated. The RAV depends additionally upon the size of the exploration budget, compared with the project, and also upon the 'price of risk'. That price is incorporated from the finance literature. The technique permits answering three related questions: 1) the risk-adjusted rate of return for a given project; 2) the risk-adjusted value of that project; or 3) the risk premium appropriate for a particular project, given the size of the firm's exploration budget.

    2015-01-01

    Global dependence on a limited number of countries for specific mineral commodities could lead to sudden supply disruptions for the United States, and barite is one such commodity. Analyses of barite supply amounts and sources for the United States are demonstrative of mineral commodities on which the country is import reliant. Mineral commodity trade flows can be analyzed more easily than import reliances for commodities in which U.S. domestic demand is primarily met by materials contained within manufactured products, as with the rare-earth elements in cellular phones and computers. Barite plays an essential role as a weighting material in drilling muds used in oil and gas drilling, primarily to prevent the explosive release of gas and oil during drilling. The Nation’s efforts to become more energy independent are based largely on the domestic oil and gas industry’s ability to explore and develop onshore and offshore fuel deposits. These activities include increased efforts by the United States to locate and recover oil and gas within unconventional deposits, such as those in the Bakken, Eagle Ford, and Marcellus Formations, using advanced drilling technologies.

  5. A methodology for handling exploration risk and constructing supply curves for oil and gas plays when resources are stacked

    International Nuclear Information System (INIS)

    Dallaire, S.M.

    1994-01-01

    The use of project economics to estimate full-cycle supply prices for undiscovered oil and gas resources is a straightforward exercise for those regions where oil and gas plays are not vertically superimposed on one another, ie. are not stacked. Exploration risk is incorporated into such an analysis by using a simple two-outcome decision tree model to include the costs of dry and abandoned wells. The decision tree model can be expanded to include multiple targets or discoveries, but this expansion requires additional drilling statistics and resource assessment data. A methodology is suggested to include exploration risk in the preparation of supply curves when stacked resources are expected and little or no information on uphole resources is available. In this method, all exploration costs for wells drilled to targets in the play being evaluated are assigned to that play, rather than prorated among the multiple targets or discoveries. Undiscovered pools are assumed to either bear all exploration costs (full cycle discoveries) or no exploration costs (half cycle discoveries). The weighted full- and half-cycle supply price is shown to be a more realistic estimate of the supply price of undiscovered pools in a play when stacked resources exist. The statistics required for this methodology are minimal, and resource estimates for prospects in other zones are not required. The equation relating the average pool finding cost to the discovery record is applicable to different scenarios regarding the presence of shallower and deeper resources. The equation derived for the two-outcome decision tree model is shown to be a special case of the general expression. 5 refs., 7 figs

    R/V Tangaroa's voyage TAN0607, 20 June to 2 July 2006, Wellington/Wellington, was the first-ever research campaign dedicated to studying gas hydrates on the Hikurangi margin. The cruise was a collaboration between GNS Science, the US Naval Research Laboratory, the National Institute of Water and Atmospheric Research, the Universities of Otago, Hawaii, and Rochester (New York), as well as individual scientists from the University of Auckland and the GeoForschungsZentrum Potsdam. We collected high-resolution seismic data, EM 300 swath bathymetry, 3.5 kHz sub-bottom, as well as 12, 38 and 120 kHz water column echosounder data. Piston cores were recovered for pore water chemistry, microbiology, core description, and paleoceanographic analyses. We acquired heatflow data using a violin-bow type probe rented from the Geological Survey of Canada. We also retrieved three dredge samples from the seafloor. Finally, Niskin bottles attached to CTDs were used to collect seawater for water-column chemistry. The cruise focused on two study areas, the Porangahau Ridge offshore of the Wairarapa and the Rock Garden off Hawke's Bay. Seismic data from 2005 showed an amplitude anomaly beneath the Porangahau Ridge that appears to be caused by gas within the regional gas hydrate stability zone and may indicate the presence of highly concentrated gas hydrates in the vicinity. We acquired nine seismic lines across the ridge to constrain the lateral extent of this anomaly. The anomaly seems to develop with folding and may be linked to enhanced fluid flow through the gas hydrate stability field, which in turn may lead to elevated gas hydrate concentration. Pore water chemistry shows a shoaling of the base of the sulfate reduction zone across this feature, indicative of elevated methane flux through the hydrate stability field. There is a distinct thermal anomaly across the Porangahau Ridge, albeit with a complex signature. On the other hand, there are no indications of methane expulsion into

    1989-02-01

    This study examined characteristics of referrals to employee assistance programs (EAP) associated with subsequent termination of employment. As well, relationships between characteristics of the referrals and program characteristics were explored. Longitudinal data were collected at several time periods for 163 referrals to EAPs from five organizations. Survival analysis was conducted to determine which variables were associated with termination of employment. Females, cohabitating couples, and employees who worked for the organization for 5 or more years were most likely to remain employed. One interesting finding was that people with alcohol problems were significantly more likely to be formal referrals.

    The Space Shuttle Transportation System is the first space program to employ the pneumatic tire as a part of space exploration. For aircraft tires, this program establishes new expectations as to what constitutes acceptable performance within a set of tough environmental and operational conditions. Tire design, stresses the usual low weight, high load, high speed, and excellent air retention features but at extremes well outside industry standards. Tires will continue to be an integral part of the Shuttle's landing phase in the immediate future since they afford a unique combination of directional control, braking traction, flotation and shock absorption not available by other systems.

    2010-12-01

    Full Text Available This article approaches the problem of selecting the non-dominated alternative for the destination of the natural gas reserves in the Mexilhão field in the Santos Basin, Brazil. Major aims of the case study reported here were to create a mechanism for assisting in the process of analyzing and selecting the best options for the destination of natural gas, and to enable the decision agent to choose the investment options best aligned to the expectations and objectives observed in the company strategies. The decision analysis employed in the study made use of the TODIM method and the THOR multicriteria decision support system. The application of both demonstrated that a decision analytic framework can be extremely useful when recommending options for upstream projects, owing to the fact that it can clearly identify the most important alternatives in the face of the scenarios tested and in relation to the criteria expressed.

  12. Exploring the Photoreduction of Au(III) Complexes in the Gas-Phase

    Marcum, Jesse C.; Kaufman, Sydney H.; Weber, J. Mathias

    2010-06-01

    We have used photodissociation spectroscopy to probe the electronic structure and photoreduction of Au(III) in gas-phase complexes containing Cl- and OH-. The gas-phase electronic spectrum of [AuCl_4]- closely resembles the aqueous solution spectrum, showing a lack of strong solvatochromic shifts. Substitution of Cl- ligands with OH- results in a strong blue shift, in agreement with ligand-field theory. Upon excitation, [AuCl_4]- can dissociate by loss of either one or two neutral Cl atoms, resulting in the reduction of gold from Au(III) to Au(II) and Au(I) respectively. The hydroxide substituted complex, [AuCl_2(OH)_2]-, demonstrates similar behavior but the only observable fragment channel is the loss of two neutral OH ligands, leading only to Au(I).

    2015-11-01

    Full Text Available Confirming thick hydrocarbon generation center and discovering thick porous reservoirs are two key factors to start the Permian gas exploration of the Western Sichuan Depression. In this paper, the Sinian-Cambrian structures of this area were studied by adopting the layer-flattening technology and the Lower Paleozoic thickness map was prepared in order to describe the Permian hydrocarbon generation center. Then, combined with seismic facies analysis and field outcrop bioherm discovery, the distribution of Middle Permian reef flat reservoirs were predicted. Finally, the favorable conditions for reef flat reservoir dolomitization were analyzed based on fault features. The study indicates that: (1 Sinian top represents a huge depression in the profile flatted by the reflecting interface of Permian bottom, with normal faults filled by thick Lower Paleozoic sediments at both sides, revealing that a aulacogen formed during the Khanka taphrogeny exists in the Western Sichuan Depression, where very thick Cambrian strata may contain hydrocarbon generation center, making Permian strata have the material conditions for the formation of large gas pools; (2 the Middle Permian strata in the Western Sichuan Depression exhibit obvious abnormal response in reef flat facies, where three large abnormal bands are developed, which are predicted as bioherm complex combined with the Middle Permian bioherm outcrop discoveries in surface; and (3 deep and large extensional faults are developed in reef flat margin, manifesting as favorable conditions for the development of dolomite reservoirs. The results show that the Middle Permian traps in the Western Sichuan Depression contain resources up to 7400 × 108 m3, showing significant natural gas exploration prospects. By far, one risk exploration well has been deployed.

    Full Text Available Gas compressor performance is vital in oil and gas industry because of the equipment criticality which requires continuous operations. Plant operators often face difficulties in predicting appropriate time for maintenance and would usually rely on time based predictive maintenance intervals as recommended by original equipment manufacturer (OEM. The objective of this work is to develop the computational model to find the isentropic head value using genetic programming. The isentropic head value is calculated from the OEM performance chart. Inlet mass flow rate and speed of the compressor are taken as the input value. The obtained results from the GP computational models show good agreement with experimental and target data with the average prediction error of 1.318%. The genetic programming computational model will assist machinery engineers to quantify performance deterioration of gas compressor and the results from this study will be then utilized to estimate future maintenance requirements based on the historical data. In general, this genetic programming modelling provides a powerful solution for gas compressor operators to realize predictive maintenance approach in their operations.

    Shale gas exploitation is the cause of many social protests. According to the protesters gas extraction technology threatens the environment: it consumes huge amounts of water, creates danger of poisoning drinking water, the formation of toxic wastewater, air contamination, noise, etc. Hydro-fracturing fluids could also leach radioactive isotopes e.g. uranium from the rock. The upper content of the main elements found in examined back flow fluids in Poland are the following: chlorine: 100.00 Kg/m 3 , sodium: 40.00 kg/m 3 , potassium: 0.90 kg/m 3 , lithium: 0.15 kg/m 3 , magnesium: 2.00 kg/m 3 , calcium: 20.00 kg/m 3 , strontium: 0.80 kg/m 3 and cesium: 0.06 kg/m 3 while the upper content of trace elements are the following: uranium: 3.5 g/m 3 , lanthanum: 12.4 g/m 3 , vanadium: 1.3 g/m 3 , yttrium: 1.3 g/m 3 , molybdenum: 2.0 g/m 3 and manganese: 9.7 g/m 3 . The recovery of uranium, and other valuable metals, from back flow fluids will reduce an environmental impact of hydro-fracturing process.

    The U.S. Geological Survey, in partnership with the U.S. Bureau of Land Management, the North Slope Borough, and the Arctic Slope Regional Corporation conducted a four-year study designed to identify, define, and delineate a shallow coalbed natural gas (CBNG) resource with the potential to provide locally produced, affordable power to the community of Wainwright, Alaska. From 2007 through 2010, drilling and testing activities conducted at three sites in or near Wainwright, identified and evaluated an approximately 7.5-ft-thick, laterally continuous coalbed that contained significant quantities of CBNG. This coalbed, subsequently named the Wainwright coalbed, was penetrated at depths ranging from 1,167 ft to 1,300 ft below land surface. Core samples were collected from the Wainwright coalbed at all three drill locations and desorbed-gas measurements were taken from seventeen 1-ft-thick sections of the core. These measurements indicate that the Wainwright coalbed contains enough CBNG to serve as a long-term energy supply for the community. Although attempts to produce viable quantities of CBNG from the Wainwright coalbed proved unsuccessful, it seems likely that with proper well-field design and by utilizing currently available drilling and reservoir stimulation techniques, this CBNG resource could be developed as a long-term economically viable energy source for Wainwright.

    2012-06-15

    In December 2009, the Ministry of Infrastructure and Environment (IandM) issued the Decree on Emission Limits for Middle Sized Combustion Installations (BEMS). This decree imposes a first-time emission limit value (ELV) of 1500 mg C/m{sup 3}{sub o} at 3% O{sub 2} for hydrocarbons emitted by gas engines. IandM used the findings of two hydrocarbon emission measurement programs, executed in 2007 and 2009, as a guideline for this initial ELV. The programs did reveal substantial variation in the hydrocarbon emissions of the gas engines tested. This variation, and especially the uncertainty as to the role of engine and/or other parameters causing such variation, was felt to hamper further policy development. IandM therefore commissioned KEMA to perform follow-up measurements on ten gas engine CHP-units in 2011. Aim of this 2011 program is to assess hydrocarbon emission variation in relation to engine parameters and process conditions including maintenance status, and to atmospheric conditions. The 2011 program comprised two identical measurement sessions, one in spring and one in winter.

    This paper presents the Conversion Project of Rio de Janeiro, Brazil, that converted all customers and the distribution network from Manufactured Gas (MG) to Natural Gas (NG), evaluating its logistic and benefits, highlighting those related to consumer safety. The Conversion Project was executed under the responsibility of CEG with the support of UERJ, specially on the definition and revision of the technical procedures as well as the quality assurance of the project execution. As main advantages followed by MG to NG network conversion, we can note: increasing of gas distribution network capacity and gas network operational condition improvements; elimination of production plant; revision and renovation of gas network; revision and repairing of building gas facilities; augmenting of NG usage; elimination of carbon monoxide as a supplied gas constituent. Conservation condition of most consumer internal gas facilities and ambient ventilation were so critical that conversion program resulted in no measurable accident prevention. The achieved safety level should be maintained through a periodically re-evaluation program of customer's gas facilities and appliances, with special focus on permanent ventilation required for NG safety usage.

    Dee, J.B.; Macken, T.

    1977-01-01

    The gas-cooled fast breeder reactor (GCFR) component development program is based on an extension of high temperature gas-cooled reactor (HTGR) component technology; therefore, the GCFR development program is addressed primarily to components which differ in design and requirements from HTGR components. The principal differences in primary system components are due to the increase in helium coolant pressure level, which benefits system size and efficiency in the GCFR, and differences in the reactor internals and fuel handling systems due to the use of the compact metal-clad core. The purpose of this paper is to present an overview of the principal component design differences between the GCFR and HTGR and the consequent influences of these differences on GCFR component development programs. Development program plans are discussed and include those for the prestressed concrete reactor vessel (PCRV), the main helium circulator and its supporting systems, the steam generators, the reactor thermal shielding, and the fuel handling system. Facility requirements to support these development programs are also discussed. Studies to date show that GCFR component development continues to appear to be incremental in nature, and the required tests are adaptations of related HTGR test programs. (Auth.)

  10. Mission Control Operations: Employing a New High Performance Design for Communications Links Supporting Exploration Programs

    Science.gov (United States)

    Jackson, Dan E., Jr.

    2015-01-01

    The planetary exploration programs demand a totally new examination of data multiplexing, digital communications protocols and data transmission principles for both ground and spacecraft operations. Highly adaptive communications devices on-board and on the ground must provide the greatest possible transmitted data density between deployed crew personnel, spacecraft and ground control teams. Regarding these requirements, this proposal borrows from research into quantum mechanical computing by applying the concept of a qubit, a single bit that represents 16 states, to radio frequency (RF) communications link design for exploration programs. This concept of placing multiple character values into a single data bit can easily make the evolutionary steps needed to meet exploration mission demands. To move the qubit from the quantum mechanical research laboratory into long distance RF data transmission, this proposal utilizes polarization modulation of the RF carrier signal to represent numbers from zero to fifteen. It introduces the concept of a binary-to-hexadecimal converter that quickly chops any data stream into 16-bit words and connects variously polarized feedhorns to a single-frequency radio transmitter. Further, the concept relies on development of a receiver that uses low-noise amplifiers and an antenna array to quickly assess carrier polarity and perform hexadecimal to binary conversion. Early testbed experiments using the International Space Station (ISS) as an operations laboratory can be implemented to provide the most cost-effective return for research investment. The improvement in signal-to-noise ratio while supporting greater baseband data rates that could be achieved through this concept justifies its consideration for long-distance exploration programs.

    2002-01-01

    The Department of Energy (DOE) is embarking upon a program to store large quantities of plutonium-bearing materials for up to fifty years. The Los Alamos National Laboratory Shelf Life Project was established to bound the behavior of plutonium-bearing material meeting the DOE 3013 Standard. The shelf life study monitors temperature, pressure and gas composition over oxide materials in a limited number of large-scale 3013 inner containers and in many small-scale containers. For the large-scale study, baseline plutonium oxides, oxides exposed to high-humidity atmospheres, and oxides containing chloride salt impurities are planned. The first large-scale container represents a baseline and contains dry plutonium oxide prepared according to the 3013 Standard. This container has been observed for pressure, temperature and gas compositional changes for less than a year. Results indicate that no detectable changes in pressure and gas composition are observed.

    Faust, Jennifer A; Nathanson, Gilbert M

    2016-07-07

    This tutorial review describes experimental aspects of two techniques for investigating collisions and reactions at the surfaces of liquids in vacuum. These gas-liquid scattering experiments provide insights into the dynamics of interfacial processes while minimizing interference from vapor-phase collisions. We begin with a historical survey and then compare attributes of the microjet and coated-wheel techniques, developed by Manfred Faubel and John Fenn, respectively, for studies of high- and low-vapor pressure liquids in vacuum. Our objective is to highlight the strengths and shortcomings of each technique and summarize lessons we have learned in using them for scattering and evaporation experiments. We conclude by describing recent microjet studies of energy transfer between O2 and liquid hydrocarbons, HCl dissociation in salty water, and super-Maxwellian helium evaporation.

  15. EXPLORING SYSTEMATIC EFFECTS IN THE RELATION BETWEEN STELLAR MASS, GAS PHASE METALLICITY, AND STAR FORMATION RATE

    Telford, O. Grace; Dalcanton, Julianne J.; Skillman, Evan D.; Conroy, Charlie

    2016-01-01

    There is evidence that the well-established mass–metallicity relation in galaxies is correlated with a third parameter: star formation rate (SFR). The strength of this correlation may be used to disentangle the relative importance of different physical processes (e.g., infall of pristine gas, metal-enriched outflows) in governing chemical evolution. However, all three parameters are susceptible to biases that might affect the observed strength of the relation between them. We analyze possible sources of systematic error, including sample bias, application of signal-to-noise ratio cuts on emission lines, choice of metallicity calibration, uncertainty in stellar mass determination, aperture effects, and dust. We present the first analysis of the relation between stellar mass, gas phase metallicity, and SFR using strong line abundance diagnostics from Dopita et al. for ∼130,000 star-forming galaxies in the Sloan Digital Sky Survey and provide a detailed comparison of these diagnostics in an appendix. Using these new abundance diagnostics yields a 30%–55% weaker anti-correlation between metallicity and SFR at fixed stellar mass than that reported by Mannucci et al. We find that, for all abundance diagnostics, the anti-correlation with SFR is stronger for the relatively few galaxies whose current SFRs are elevated above their past average SFRs. This is also true for the new abundance diagnostic of Dopita et al., which gives anti-correlation between Z and SFR only in the high specific star formation rate (sSFR) regime, in contrast to the recent results of Kashino et al. The poorly constrained strength of the relation between stellar mass, metallicity, and SFR must be carefully accounted for in theoretical studies of chemical evolution.

    Since the program initiation in October 1979, the Garrett/Ford Advanced Gas Turbine Program, designated AGT101, has made significant progress in developing ceramic technology for gas turbine applications. Successful component development has resulted in engine tests with an all ceramic hot section to temperatures up to 2200F (1204C) and full speed operation to 100,000 rpm (turbine rotor tip speed of 2300 ft/sec (701 m/s)). An 85-hour test was performed on an all ceramic engine at 2200F (1204C) turbine inlet temperature. These engine tests represent important first steps in the development of ceramic materials and technology. Engine evaluation was preceded by important component development. Activities included aerodynamic component evaluation and development of a high temperature foil bearing to support the ceramic turbine rotor. Development of low leakage regenerator seals and static ceramic seals in this high temperature environment were critical to engine performance.

    Supporting positive mental health development in adolescents is a major public health concern worldwide. Although several school-based programs aimed at preventing depression have been launched, it is crucial to evaluate these programs and to obtain feedback from participating adolescents. This study aimed to explore adolescents' experiences with a -based cognitive-behavioral depression prevention program. Eighty-nine adolescents aged 13-15 years were divided into 12 focus groups. The focus group interviews were analyzed using qualitative content analysis. Three categories and eight subcategories were found to be related to the experience of the school-based program. The first category, intrapersonal strategies, consisted of the subcategories of directed thinking, improved self-confidence, stress management, and positive activities. The second category, interpersonal awareness, consisted of the subcategories of trusting the group and considering others. The third category, structural constraints, consisted of the subcategories of negative framing and emphasis on performance. The school-based mental health program was perceived as beneficial and meaningful on both individual and group levels, but students expressed a desire for a more health-promoting approach.

    Several concepts are being evaluated in the US HTR Program to explore designs which might improve the commercial viability of nuclear power. The general approach is to reduce the reactor power and increase the ability to use inherent features for removing heat following extreme accidents. The unit size and design of these concepts are constrained so that extreme accidents do not result in significant release of radioactivity from the reactor plant. Through the greater reliance on inherent safety features in small HTRs, it should be possible to minimize the amount of nuclear grade components required in the balance-of-plant, which could lead to an economic system. Four HTR concepts are presently being evaluated within the US Program, and these concepts are briefly summarized. A modular HTR using a steel pressure vessel, which is very similar to one of the four HTR concepts being evaluated within the US National program, is presented as an example of a specific concept to illustrate the features and performance of HTRs having a high degree of inherent safety

    Ionic liquids (ILs) show brilliant performance in separating gas impurities, but few researchers have performed an in-depth exploration of the bulk and interface behavior of penetrants and ILs thoroughly. In this research, we have performed a study on both molecular dynamics (MD) simulation and quantum chemical (QC) calculation to explore the transport of acetylene and ethylene in the bulk and interface regions of 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM]-[BF4]). The diffusivity, solubility and permeability of gas molecules in the bulk were researched with MD simulation first. The subdiffusion behavior of gas molecules is induced by coupling between the motion of gas molecules and the ions, and the relaxation processes of the ions after the disturbance caused by gas molecules. Then, QC calculation was performed to explore the optical geometry of ions, ion pairs and complexes of ions and penetrants, and interaction potential for pairs and complexes. Finally, nonequilibrium MD simulation was performed to explore the interface structure and properties of the IL-gas system and gas molecule behavior in the interface region. The research results may be used in the design of IL separation media.

    The authors have operationalized firm-specific exploration efficiency as the difference between a firm-specific intercept estimated in a fixed-effects panel data Cobb-Douglas production frontier model and the maximum firm-specific intercept estimated in that model. The production model was estimated during two different time periods, 1982--1985 and 1989--1992, allowing efficiency to vary intertemporally. This efficiency estimate served as a benchmark against which they compared various measures of inverse finding costs. They assumed that the degree of association with an efficiency benchmark is an important attribute of any finding cost measure and that, further, the degree of association may be used as a metric for choosing between alternative finding cost measures. Accordingly, they evaluated the cross-sectional statistical association between estimated efficiency and alternative inverse finding cost measures. They discovered that the inverse finding cost measure that exhibited the strongest association with efficiency during the two time periods was a three-year moving-average finding cost which included exploration plus development expenditures as costs and reserve extensions and additions plus revisions as the units added

    The Acceptance Program for dental materials and devices and the general guidelines for submission of products have been reported in the Journal (88:615 March 1974). At its April 1977 meeting, the Council included equipment for scavenging and monitoring trace nitrous oxide gas in its Acceptance Program. The Council has established the effective date for classification of products under these two sets of guidelines as one year from the date of publication of this announcement. After that date, classification of a product will be required before promotion or exhibition in Association media.

    In the United States (US) there are currently voluntary reporting programs (EPA Climate Leaders, Carbon Disclosure Project and The Climate Registry), organized market-based trading platforms (Chicago Climate Exchange and The Green Exchange) and proposed regional mandatory cap and trade programs in California, the Northeast, the West and the Midwest. The past success of the US Acid Rain 'cap-and-trade' system market-based format together with the availability of the European Union Emission Trading Scheme to serve as a template for future greenhouse gas regulations is promising as the US can participate in the world wide carbon markets already established.

    Massive hydraulic fracture diagnostic experiments continued in FY 79 with the major activity being focused on the development of wireline tool instrumentation. Nevada Test Site substantiate field data obtained in two experiments with Amoco in their Wattenberg field. A high-resolution, three-dimensional seismic survey program was initiated. The program will start with some experiments at shallow depths where the sand lenses outcrop and then move into greater depths to evaluate this technique. A logging program was also established to evaluate formation properties. Hydraulic and dynamic fracturing experiments were conducted adjacent to a tunnel complex at the Nevada Test Site and which are then directly observed by mining through the experiment area. Evaluation of fracturing tests at an interface between geologic formations with significantly different properties showed that the interface did not contain the fractures. A microcrack model has been formulated which downplays the importance of material properties and emphasizes the role of in-situ stresses for processes occurring at a crack tip. Multiple fracturing from a wellbore has been demonstrated for a High Energy Gas Frac concept. Finally, a Multi-Well Experiment has been defined whose objectives are to characterize in detail a lenticular gas reservoir of the Western United States and to evaluate state-of-the-art and developing technology for the recovery of gas from them.

    Multipurpose Research Reactor G.A. Siwabessy (RSG-GAS) which has been operating since 1987 is one of the main facilities on supporting research, development and application of nuclear energy programs in BATAN. Until now, the RSG-GAS research reactor has been successfully operated safely and securely. However, because it has been operating for nearly 30 years, the structures, systems and components (SSCs) from the reactor would have started experiencing an aging phase. The process of aging certainly causes a decrease in reliability and safe performances of the reactor, therefore the aging management program is needed to resolve the issues. One of the programs in the aging management is to evaluate the safety and reliability of the system and also screening the critical components to be managed.One method that can be used for such purposes is the Fault Tree Analysis (FTA). In this papers FTA method is used to screening the critical components in the RSG-GAS Primary Cooling System. The evaluation results showed that the primary isolation valves are the basic events which are dominant against the system failure.

    Full Text Available Balsamic vinegar is a popular food condiment produced from cooked grape must by two successive fermentation (anaerobic and aerobic processes. Although many studies have been performed to determine the composition of major metabolites, including sugars and aroma compounds, no study has been undertaken yet to characterize the comprehensive metabolite composition of balsamic vinegars. Here, we present the first metabolomics study of commercial balsamic vinegars by gas chromatography coupled to mass spectrometry (GC-MS. The combination of three GC-MS methods allowed us to detect >1500 features in vinegar samples, of which 123 metabolites were accurately identified, including 25 amino acids, 26 carboxylic acids, 13 sugars and sugar alcohols, four fatty acids, one vitamin, one tripeptide and over 47 aroma compounds. Moreover, we identified for the first time in vinegar five volatile metabolites: acetin, 2-methylpyrazine, 2-acetyl-1-pyroline, 4-anisidine and 1,3-diacetoxypropane. Therefore, we demonstrated the capability of metabolomics for detecting and identifying large number of metabolites and some of them could be used to distinguish vinegar samples based on their origin and potentially quality.

  10. Exploring the assumed invariance of implied emission factors for forest biomass in greenhouse gas inventories

    Reviews of each nation's annual greenhouse gas inventory submissions including forestland are part of the ongoing reporting process of the United Nations Framework Convention on Climate Change. Goals of these reviews include improving quality and consistency within and among reports. One method of facilitating comparisons is the use of a standard index such as an implied emission factor (IEF), which for forest biomass indicates net rate of carbon emission or sequestration per area. Guidance on the use of IEFs in reviews is limited, but there is an expectation that values should be relatively constant both over time and across spatial scales. To address this hypothesis, we examine IEFs over time, derived from U.S. forests at plot-, state-, and national-levels. Results show that at increasingly aggregated levels, relative heterogeneity decreases but can still be substantial. A net increase in U.S. whole-forest IEFs over time is consistent with results from temperate forests of nations in the European Community. IEFs are better viewed as a distribution of values rather than one constant value principally because of sensitivities to productivity, disturbance, and land use change, which can all vary considerably across a nation's forest land.

    This study is to acquaint the oil geologist, reservoir engineer, and manager with modern methods of appraising geological/technical projects and decision problems under uncertainty. Uncertainty attaches to any appraisal of investment projects whose income lies in the future. The greater that uncertainty, the less important become the appraisal methods proper while the computation procedures concerning uncertainty gain in significance. There are briefly discussed the tools of risk determination, i.e., mathematical statistics and probability theory, and some of the most common methods of quantifying the uncertainty are explained. The best known methods of decision finding under multivalent or uncertain expectations, such as conditional and sensibility analyses, minimax and minimax-risk rule, and preference theory are set forth. The risk is defined, and the most common methods of genuine risk determination in exploration and exploitation are discussed. Practical examples illustrate the solution of decision problems under uncertainty, and examples of genuine risk determination are furnished. (29 refs.)

    Measurements of Rn-gas concentrations and Working Level (WL), were carried out in the U-exploration galleries at El- Allouga Mine, Sinai, Egypt by passive techniques (SSNTD) during the four seasons ( Summer, Fall, Winter and Spring) using four different detector types: CR-39, MK, CN-85 and LR-115.Twenty eight (28) stations were chosen for this purpose reflecting different environmental conditions as measurement sites within the galleries. The Rn-gas concentrations , in the summer period ranged from 25.86 to 44.2 pCi/l in the ventilated stations and from 488.98 to 611.16 pCi/l in the non-ventilated stations. In the fall period , the average Rn-gas concentrations in the ventilated stations ranged from 31.61 to 56.36 pCi/l while in the non-ventilated stations from 457.61 to 621.52 pCi/l. In the winter period, the average Rn-gas concentrations in the ventilated stations ranged from 27.59 to 66.45 pCi/l while in the non- ventilated stations from 499.09 to 603.81 pCi/l. In the spring the Rn-gas concentrations ranged from 30.8 to 46.77 pCi/l in the ventilated stations, whereas, in the non-ventilated stations from 404.06 to 445.18 pCi/l. The (WL), in the summer period, ranged from 0.143 to 0.247 in the ventilated sector and from 4.408 to 5.497 in the non-ventilated stations .In fall, the( WL) ranged from 0.166 to 0.295 in the ventilated stations and from 4.123 to 5.624 in the non-ventilated stations. In the winter, the (WL) ranged from 0.105 to 0.37 in the ventilated stations and from 4.138 to 5.26 in the non-ventilated stations. In the spring, the (WL) in the ventilated stations ranged from 0.152 to 0.241 and from 3.696 to 4.087 in the non-ventilated stations. These results indicate that: i)The low measured Rn gas and (WL) values in the ventilated stations reflect the effect of variations in meteorological conditions on (WL) determination where the air flow carries the Rn-gas before it decays and the daughters are plated onto the SSNTD . ii) The larger ranges for Rn-gas

  13. Towards Interactive Visual Exploration of Parallel Programs using a Domain-Specific Language

    The use of GPUs and the massively parallel computing paradigm have become wide-spread. We describe a framework for the interactive visualization and visual analysis of the run-time behavior of massively parallel programs, especially OpenCL kernels. This facilitates understanding a program\\'s function and structure, finding the causes of possible slowdowns, locating program bugs, and interactively exploring and visually comparing different code variants in order to improve performance and correctness. Our approach enables very specific, user-centered analysis, both in terms of the recording of the run-time behavior and the visualization itself. Instead of having to manually write instrumented code to record data, simple code annotations tell the source-to-source compiler which code instrumentation to generate automatically. The visualization part of our framework then enables the interactive analysis of kernel run-time behavior in a way that can be very specific to a particular problem or optimization goal, such as analyzing the causes of memory bank conflicts or understanding an entire parallel algorithm.

    The Solar System Exploration Education Forum has worked for five years to foster Education and Public Outreach (E/PO) cooperation among missions and programs in order to leverage resources and better meet the needs of educators and the public. These efforts are coming together in a number of programs and products and in '2004 - The Year of the Solar System.' NASA's practice of having independent E/PO programs for each mission and its public affairs emphasis on uniqueness has led to a public perception of a fragmented solar system exploration program. By working to integrate solar system E/PO, the breadth and depth of the solar system exploration program is revealed. When emphasis is put on what missions have in common, as well as their differences, each mission is seen in the context of the whole program.

    2016-10-01

    Full Text Available The dolomite reservoirs of the Lower Cambrian Longwangmiao Fm in the Gaoshiti–Moxi area, Sichuan Basin, are deeply buried (generally 4400–4900 m, with high heterogeneity, making reservoir prediction difficult. In this regard, key seismic exploration technologies were developed through researches. Firstly, through in-depth analysis on the existing geologic, drilling, seismic data and available research findings, basic surface and subsurface structures and geologic conditions within the study area were clarified. Secondly, digital seismic data acquisition technologies with wide azimuth, wide frequency band and minor bins were adopted to ensure even distribution of coverage of target formations through optimization of the 3D seismic geometry. In this way, high-accuracy 3D seismic data can be acquired through shallow, middle and deep formations. Thirdly, well-control seismic data processing technologies were applied to enhance the signal-to-noise ratio (SNR of seismic data for deep formations. Fourthly, a seismic response model was established specifically for the Longwangmiao Fm reservoir. Quantitative prediction of the reservoir was performed through pre-stack geo-statistics. In this way, plan distribution of reservoir thicknesses was mapped. Fifthly, core tests and logging data analysis were conducted to determine gas-sensitive elastic parameters, which were then used in pre-stack hydrocarbon detection to eliminate the multiple solutions in seismic data interpretation. It is concluded that application of the above-mentioned key technologies effectively promote the discovery of largescale marine carbonate gas reservoirs of the Longwangmiao Fm.

    2013-03-27

    The development of comprehensive two-dimensional gas chromatography (GC x GC) has expanded the analytical window for studying complex mixtures like oil. Compared to traditional gas chromatography, this technology separates and resolves at least an order of magnitude more compounds, has a much larger signal to noise ratio, and sorts compounds based on their chemical class; hence, providing highly refined inventories of petroleum hydrocarbons in geochemical samples that was previously unattainable. In addition to the increased resolution afforded by GC x GC, the resulting chromatograms have been used to estimate the liquid vapor pressures, aqueous solubilities, octanol-water partition coefficients, and vaporization enthalpies of petroleum hydrocarbons. With these relationships, powerful and incisive analyses of phase-transfer processes affecting petroleum hydrocarbon mixtures in the environment are available. For example, GC x GC retention data has been used to quantitatively deconvolve the effects of phase transfer processes such as water washing and evaporation. In short, the positive attributes of GC x GC-analysis have led to a methodology that has revolutionized the analysis of petroleum hydrocarbons. Overall, this research has opened numerous fields of study on the biogeochemical "genetics" (referred to as petroleomics) of petroleum samples in both subsurface and surface environments. Furthermore, these new findings have already been applied to the behavior of oil at other seeps as well, for petroleum exploration and oil spill studies.

    A combined data analysis and theoretical program aimed at interpreting and utilizing solar wind data obtained from Pioneer 6, Mariner 5, and Explorer 35 has been completed. A theoretical model of the radial dependence of large scale solar wind inhomogeneities was developed and used to map solar wind variations measured by Explorer 35 to various heliocentric distances and to the orbits of Mercury, Venus, and Mars. The model was also used to determine power spectra velocity, density and temperature variations of 20 R sub s from spectra obtained from the Mariner 5 data at an average heliocentric distance of 180 R sub s. Five stream-stream interaction events in the Pioneer 6 data were analyzed which confirmed the picture of a spiral compression ridge interfacing the two streams and the associated east-west deflections of the solar wind flow. Magnetopause crossings observed in Explorer 35 plasma data were used to develop statics on boundary motions at lunar distance. A study of the geomagnetic disturbance field asymmetry was performed and a model of disturbance field from a partial ring current was developed.

    Pipelines have the highest capacity and are the safest and the least environmentally disruptive way for gas or oil transmission. Recently, failures due to corrosion defects have become of major concern in maintaining pipeline integrity. A number of solutions have been developed for the assessment of remaining strength of corroded pipelines. However, these solutions are known to be dependent on material properties and pipeline geometries. In this paper, a fitness-for-purpose type limit load solution for corroded gas pipelines made of the X65 steel is proposed. For this purpose, a series of burst tests with various types of corrosion defects are performed. Finite element simulations are carried out to derive an appropriate failure criterion. And then, further, extensive finite element analyses are performed to obtain the FFP type limit load solution for corroded X65 gas pipelines as a function of defect depth, length and pipeline geometry. And also, a window based computer program for the assessment of corrosion defect, which is named as COPAP(COrroded Pipeline Assessment Program) has been developed on the basis of proposed limit load solution

    An examination is made of the program support of the Automated System of Planned Calculations (ASPC) of the oil and Gas Extracting Administration (OGEA). Specific requirements for the ASPC of the OGEA are indicated and features of its program realization. In developing the program support of the system, an approach of parametric programming was used. A formal model of the ASPC OGEA is described in detail. It was formed in a theoretical-multiple language. Sets with structure of a tree are examined. They illustrate the production and administrative hierarchical structure of the planning objects in the oil region. The top of the tree corresponds to the OGEA as a whole. In the simplest realization, the tree has two levels of hierarchy: association and field. In general features, a procedure is described for possible use of the system by the planning workers. A plan is presented for program support of the ASPC OGEA, in light of whose specific nature a large part of the programs which realize this system are written in a language ASSEMBLER.

    The use of GPUs and the massively parallel computing paradigm have become wide-spread. We describe a framework for the interactive visualization and visual analysis of the run-time behavior of massively parallel programs, especially OpenCL kernels. This facilitates understanding a program's function and structure, finding the causes of possible slowdowns, locating program bugs, and interactively exploring and visually comparing different code variants in order to improve performance and correctness. Our approach enables very specific, user-centered analysis, both in terms of the recording of the run-time behavior and the visualization itself. Instead of having to manually write instrumented code to record data, simple code annotations tell the source-to-source compiler which code instrumentation to generate automatically. The visualization part of our framework then enables the interactive analysis of kernel run-time behavior in a way that can be very specific to a particular problem or optimization goal, such as analyzing the causes of memory bank conflicts or understanding an entire parallel algorithm.

    1978-09-01

    This report describes and evaluates several gas-cooled reactor plant concepts under development within the Federal Republic of Germany (FRG). The concepts, based upon the use of a proven Pebble Bed Reactor (PBR) fuel element design, include nuclear heat generation for chemical processes and electrical power generation. Processes under consideration for the nuclear process heat plant (PNP) include hydrogasification of coal, steam gasification of coal, combined process, and long-distance chemical heat transportation. The electric plant emphasized in the report is the steam turbine cycle (HTR-K), although the gas turbine cycle (HHT) is also discussed. The study is a detailed description and evaluation of the nuclear portion of the various plants. The general conclusions are that the PBR technology is sound and that the HTR-K and PNP plant concepts appear to be achievable through appropriate continuing development programs, most of which are either under way or planned

    Scientists, science experts, graduate and even undergraduate student researchers have a unique ability to inspire the next generation of explorers. These science, technology, engineering, and mathematics (STEM) experts can serve as role models for students and can help inspire them to consider future STEM-related careers. They have an exceptional ability to instill a sense of curiosity and fascination in the minds of students as they bring science to life in the classroom. Students and teachers are hungry for opportunities to interact with scientists. They feel honored when these experts take time out of their busy day to share their science, their expertise, and their stories. The key for teachers is to be cognizant of opportunities to connect their students with scientists. For scientists, the key is to know how to get involved, to have options for participation that involve different levels of commitment, and to work with educational specialists who can help facilitate their involvement. The Expedition Earth and Beyond (EEAB) Program, facilitated by the Astromaterials Research and Exploration Science (ARES) Directorate at the NASA Johnson Space Center, is an Earth and planetary science education program designed to inspire, engage, and educate teachers and students by getting them actively involved with NASA exploration, discovery, and the process of science. One of the main goals of the program is to facilitate student research in the classroom. The program uses astronaut photographs, provided through the ARES Crew Earth Observations (CEO) payload on the International Space Station (ISS) as the hook to help students gain an interest in a research topic. Student investigations can focus on Earth or involve comparative planetology.

  7. Sustaining Petroleum Exploration and Development in Mature Basins: Production Sharing Contracts and Financing of Joint Venture Oil and Gas Projects

    NNPC is not always secure, adequate funding for the joint venture has sometimes run into difficulties. Similarly, private indigenous companies, run into similar budget difficulties because of the relative high investment cash required by these ventures. Innovative ideas, usually involving forms of disproportionate financing, have to be found to overcome the funding difficulties. These have given rise to various types of 'carry' arrangements in which the 'carrying' party is rewarded in kind. In less mature provinces where technical (exploration and production) risks are very high, the business employs expensive and cutting edge technology, the burden for the development of such assets is borne mostly by IOCs through what is now generally referred to as Production Sharing Agreement (PSA). Under a PSA, the IOC operates the venture as a contractor for the state and recovers its investments through a share of the production. PSA has become an acceptable arrangement for financing oil and gas projects outside the Western World. It is especially suited for operations in new areas of the developing world characterised by weak economies and non-convertible currencies. However, each developing country has adapted the PSA to suit its local environment and conditions. We now have a variety of PSAs ranging from the classical PSA developed in Indonesia and Russia with traditional cost oil and profit oil recovery mechanism to the net-production share mechanism, which case an additional element of tax oil become necessary to ensure that the revenue flow to the government is maintained at all times. However, this arrangement can become a major challenge for the partners

  8. A mixed-methods exploration of an environment for learning computer programming

    Full Text Available A mixed-methods approach is evaluated for exploring collaborative behaviour, acceptance and progress surrounding an interactive technology for learning computer programming. A review of literature reveals a compelling case for using mixed-methods approaches when evaluating technology-enhanced-learning environments. Here, ethnographic approaches used for the requirements engineering of computing systems are combined with questionnaire-based feedback and skill tests. These are applied to the ‘Ceebot’ animated 3D learning environment. Video analysis with workplace observation allowed detailed inspection of problem solving and tacit behaviours. Questionnaires and knowledge tests provided broad sample coverage with insights into subject understanding and overall response to the learning environment. Although relatively low scores in programming tests seemingly contradicted the perception that Ceebot had enhanced understanding of programming, this perception was nevertheless found to be correlated with greater test performance. Video analysis corroborated findings that the learning environment and Ceebot animations were engaging and encouraged constructive collaborative behaviours. Ethnographic observations clearly captured Ceebot's value in providing visual cues for problem-solving discussions and for progress through sharing discoveries. Notably, performance in tests was most highly correlated with greater programming practice (p≤0.01. It was apparent that although students had appropriated technology for collaborative working and benefitted from visual and tacit cues provided by Ceebot, they had not necessarily deeply learned the lessons intended. The key value of the ‘mixed-methods’ approach was that ethnographic observations captured the authenticity of learning behaviours, and thereby strengthened confidence in the interpretation of questionnaire and test findings.

  9. Exploring how prison-based drug rehabilitation programming shapes racial disparities in substance use disorder recovery.

    Prison-based therapeutic community (TC) programming is derived from the perspective that drug addiction is primarily symptomatic of cognitive dysfunction, poor emotional management, and underdeveloped self-reliance skills, and can be addressed in a collaborative space where a strong ideological commitment to moral reform and personal responsibility is required of its members. In this space, evidence of rehabilitation is largely centered on the client's relationship to language and the public adoption of a "broken self" narrative. Failure to master these linguistic performances can result in the denial of material and symbolic resources, thus participants learn how to use TC language to present themselves in ways that support existing institutionalized hierarchies, even if that surrender spells their self-denigration. This research examines the interview narratives of 300 former prisoners who participated in a minimum of 12 months of prison-based TC programming, and described how programming rhetoric impacted their substance abuse treatment experiences. While many of the respondents described distressing experiences as TC participants, White respondents were more likely to eventually embrace the "addict" label and speak of privileges and reintegrative support subsequently received. Black respondents were more likely to defy the treatment rhetoric, and either fail to complete the program or simulate a deficit-based self-narrative without investing in the content of those stories. The following explores the significance of language and identity construction in these carceral spaces, and how treatment providers as well as agency agendas are implicated in the reproduction of racial disparities in substance abuse recovery.

    There is general scientific consensus that global warming is occurring and that this results from human activities, primarily burning fossil fuels. There is also a growing international consensus that the most cost-effective way to slow global warming is to establish international climate change trading programs that let institutions sell greenhouse gas (GHG) reductions in an international trading program. A well designed international GHG trading program could save billions or tens of billions of dollars and could result in a more rapid transfer of cleaner, more modern energy generating, transmitting and using technologies to developing nations. Establishing an international GHG trading program will require the development of international consensus rules on how to value and credit investments, for example in energy efficiency, that result in reduced emissions of greenhouse gases. Such a program would require the development of an international technical agreement on how to value emissions reductions attributed to energy-efficiency investments that reflect realistic estimates of future energy savings--and emissions reductions--that come from those investments. This paper examines five possible approaches for valuing energy savings which might serve as the basis for an international agreement, discusses the strengths and weaknesses of each approach, and discusses lessons learned from conducting this evaluation process

    Neutral atom imaging of the interstellar gas flow in the inner heliosphere provides the most detailed information on physical conditions of the surrounding interstellar medium (ISM) and its interaction with the heliosphere. The Interstellar Boundary Explorer (IBEX) measured neutral H, He, O, and Ne for three years. We compare the He and combined O+Ne flow distributions for two interstellar flow passages in 2009 and 2010 with an analytical calculation, which is simplified because the IBEX orientation provides observations at almost exactly the perihelion of the gas trajectories. This method allows separate determination of the key ISM parameters: inflow speed, longitude, and latitude, as well as temperature. A combined optimization, as in complementary approaches, is thus not necessary. Based on the observed peak position and width in longitude and latitude, inflow speed, latitude, and temperature are found as a function of inflow longitude. The latter is then constrained by the variation of the observed flow latitude as a function of observer longitude and by the ratio of the widths of the distribution in longitude and latitude. Identical results are found for 2009 and 2010: an He flow vector somewhat outside previous determinations (λ ISM∞ = 79. 0 0+3. 0 0(–3. 0 5), β ISM∞ = –4. 0 9 ± 0. 0 2, V ISM∞ 23.5 + 3.0(–2.0) km s –1 , T He = 5000-8200 K), suggesting a larger inflow longitude and lower speed. The O+Ne temperature range, T O+Ne = 5300-9000 K, is found to be close to the upper range for He and consistent with an isothermal medium for all species within current uncertainties.

  14. Beyond SHARP-- Primary Formaldehyde from Oil and Gas Exploration and Production in the Gulf of Mexico Region

    Olaguer, E. P.

    2010-12-01

    Formaldehyde has been named by the EPA as a hazardous air pollutant that may be carcinogenic and also cause irritation to the eyes, nose, throat and lung. Moreover, it is a powerful radical and ozone precursor. The 2009 Study of Houston Atmospheric Radical Precursors (SHARP) was conceived by the Houston Advanced Research Center (HARC) on behalf of the Texas Environmental Research Consortium (TERC) to examine the relative importance of primary and secondary formaldehyde (HCHO) and nitrous acid (HONO) in ozone formation. SHARP confirmed that primary combustion sources of HCHO, such as flares end engines, may be underestimated (by an order of magnitude or more) in official emission inventories used for the purpose of air quality modeling in highly industrialized areas such as Houston. This presentation provides recently generated modeling and observational evidence that the same may be true in both rural and urban areas with oil and gas exploration and production (E&P) activities, such as the Upper Green River Basin of Wyoming and the Barnett Shale of Texas. Oil and gas E&P is increasing in the Gulf of Mexico region, particularly in the Barnett, Haynesville, Eagle Ford, Cana-Woodford, and Fayetteville shale basins. In the Barnett Shale, E&P activities are moving into urban neighborhoods, and may affect the ability to bring the Dallas-Ft. Worth region into attainment of the federal ozone standard. Data concerning formaldehyde emissions from drill rig and pipeline compressor engines, flares, and glycol or amine reboilers, should be obtained in order to more accurately model air quality in the Gulf of Mexico region.

    Cultural diversity among students in tertiary institutions in Australia and globally has increased rapidly in the last decade, and is continuing to do so. Focus groups were held at the University of Newcastle, NSW to: (1) examine the specific needs of international students in the Master of Pharmacy, Bachelor of Medicine and Bachelor of Nursing programs in relation to language and cultural considerations and (2) to understand the attitudes of domestic students to the cultural issues faced among their peers. The project explored these issues with the intention to inform curricula changes to accommodate the needs of culturally and linguistically diverse students. The key themes emerging from international students were: difficulties in spoken language, differences in professional roles and expectations, differences in methods of learning, inadequate social interaction outside the classroom and acceptance of differences in cultural and religious practices. The domestic student views reinforced the comments from international students both in regard to social interaction and in regard to participation in class discussions. Although local students were interested in learning from international students about their culture and religious beliefs, there were limited initiatives from both sides. There is a need for tertiary institutions that benefit economically from increasing the numbers of international students to help them to study and live in a new environment. Assistance needs to go beyond learning the English language to helping students understand its use in a professional context (health terminology and slang used by patients), the nuances of the health professional disciplines in a western society, the approach to study and problem-based learning styles and skills to assist with social interaction. The results of the present exploration have led to a series of proposed actions for the University of Newcastle. These recommendations are applicable to any "Western

    The natural assimilation of the process through which health partners sustain long-term relationships is a key issue in maintaining social well-being, reducing health risk factors, and sustaining public health programs. One global initiative in building effective healthcare systems is public-private partnerships (PPPs). This study elucidates the proposed key performance indicators initiated by the Ministry of Health of Saudi Arabia based on the projections of the government, known as Vision 2030, from the perspective of health risk factors. Through an inductive content analysis, this study assessed primary and secondary data in relation to the Saudi National Transformation Program (NTP). To identify the institutions that played a role in formulating the new Saudi Healthcare System, health policies, regulations, and reports published between 1996 and 2016 were categorized. After ranking the risk factors, the investigator selected 13 healthcare professionals in four focus group interviews to insightfully explore the challenges that the NTP faces from a health risk perspective. Thus, the study employed qualitative data gathered through focus group interviews with key figures as well as data extracted from written sources to identify distinct but interrelated partnerships practiced within risk management. A methodological overview of NTP priority and implementation offered practical guidance in the healthcare context. The five critical factors in maintaining successful and sustainable PPPs were (1) trustworthiness, (2) technological capability, (3) patient-centeredness, (4) competence, and (5) flexibility. Concession on primary and secondary healthcare services might be a good option based on the literature review and considering its popularity in other countries. A high outcome-based risk of PPPs was found as the most commonly shared perspective in risk management. Although the impact of the NTP rise has yet to be explored, its potential for challenging health

    Indonesia depends heavily on revenues from the export of LNG and oil, the availability of which appears to be decreasing. It is therefore making a strong effort to accelerate development of a domestic natural gas industry. A high priority has been given to the conversion of power plants and city gas systems, including local industries and commercial facilities, from liquid fuels to natural gas. This will release more oil for export, help to meet the objectives of Repelita V, and provide substantial environmental benefits. The World Bank recently provided loans to the Indonesian Government for two projects that are aimed at substituting natural gas for oil and manufactured gas in domestic markets. One project involves expansion of the gas distribution systems of Indonesia's natural gas utility (PGN) in three cities: Jakarta and Bogor in Java, and Medan in Sumatra. The project also includes training programs for PGN staff and an energy pricing policy study to be carried out by Indonesia's Ministry of Mines and Energy. The second project involves expansion of the supply of natural gas for Surabaya and twelve other towns in its vicinity in East Java, and further expansion of Medan's supply system. Technical assistance will be provided to enhance the skills ofPGN and the Ministry of Mines and Energy, and a Gas Technology Unit similar to the Institute of Gas Technology will be established at Indonesia's Research and Development Center for Oil and Gas (LEMIGAS) in Jakarta. 14 refs., 3 figs., 11 tabs

    1981-03-01

    The purpose of this document is to present a safety plan as part of an overall program plan for the design and development of the High Temperature Gas-Cooled Reactor (HTGR). This plan is intended to establish a logical framework for identifying the technology necessary to demonstrate that the requisite degree of public risk safety can be achieved economically. This plan provides a coherent system safety approach together with goals and success criterion as part of a unifying strategy for licensing a lead reactor plant in the near term. It is intended to provide guidance to program participants involved in producing a technology base for the HTGR that is fully responsive to safety consideration in the design, evaluation, licensing, public acceptance, and economic optimization of reactor systems.

    The present paper deals with the preparation and characterization of La/Ce mixed oxides, with La molar contents of 20, 36 and 57%. We carry out the study of the structural, textural and redox properties of the mixed oxides, comparing our results with those for pure ceria. For this aim we use temperature programmed reduction (TPR), temperature programmed desorption (TPD), nitrogen physisorption at 77 K, X-ray diffraction and high resolution electron microscopy. The mixed oxides are more easy to reduce in a flow of hydrogen than ceria. Moreover, in an inert gas flow they release oxygen in higher amounts and at lower temperatures than pure CeO 2 . The textural stability of the mixed oxides is also improved by incorporation of lanthana. All these properties make the ceria-lanthana mixed oxides interesting alternative candidates to substitute ceria in three-way catalyst formulations. (orig.)

    2007-12-01

    Japan Oil, Gas and Metals National Corporation (JOGMEC) and Natural Resource Canada (NRCan) have embarked on a new research program to study the production potential of gas hydrates. The program is being carried out at the Mallik gas hydrate field in the Mackenzie Delta, a location where two previous scientific investigations have been carried in 1998 and 2002. In the 2002 program that was undertaken by seven partners from five countries, 468m3 of gas flow was measured during 124 hours of thermal stimulation using hot warm fluid. Small-scale pressure drawdown tests were also carried out using Schlumberger's Modular Dynamics Tester (MDT) wireline tool, gas flow was observed and the inferred formation permeabilities suggested the possible effectiveness of the simple depressurization method. While the testing undertaken in 2002 can be cited as the first well constrained gas production from a gas hydrate deposit, the results fell short of that required to fully calibrate reservoir simulation models or indeed establish the technical viability of long term production from gas hydrates. The objectives of the current JOGMEC/NRCan/Aurora Mallik production research program are to undertake longer term production testing to further constrain the scientific unknowns and to demonstrate the technical feasibility of sustained gas hydrate production using the depressurization method. A key priority is to accurately measure water and gas production using state-of-art production technologies. The primary production test well was established during the 2007 field season with the re-entry and deepening of JAPEX/JNOC/GSC Mallik 2L-38 well, originally drilled in 1998. Production testing was carried out in April of 2007 under a relatively low drawdown pressure condition. Flow of methane gas was measured from a 12m perforated interval of gas-hydrate-saturated sands from 1093 to 1105m. The results establish the potential of the depressurization method and provide a basis for future

  2. Fuel Cell Development for NASA's Human Exploration Program: Benchmarking with "The Hydrogen Economy"

    The theoretically high efficiency and low temperature operation of hydrogen-oxygen fuel cells has motivated them to be the subject of much study since their invention in the 19th Century, but their relatively high life cycle costs kept them as a "solution in search of a problem" for many years. The first problem for which fuel cells presented a truly cost effective solution was that of providing a power source for NASA's human spaceflight vehicles in the 1960 s. NASA thus invested, and continues to invest, in the development of fuel cell power plants for this application. This development program continues to place its highest priorities on requirements for minimum system mass and maximum durability and reliability. These priorities drive fuel cell power plant design decisions at all levels, even that of catalyst support. However, since the mid-1990's, prospective environmental regulations have driven increased governmental and industrial interest in "green power" and the "Hydrogen Economy." This has in turn stimulated greatly increased investment in fuel cell development for a variety of commercial applications. This investment is bringing about notable advances in fuel cell technology, but, as these development efforts place their highest priority on requirements for minimum life cycle cost and field safety, these advances are yielding design solutions quite different at almost every level from those needed for spacecraft applications. This environment thus presents both opportunities and challenges for NASA's Human Exploration Program

    : Purpose: This study aimed to address the knowledge gap between implementing and sustaining evidence-based fall prevention practices for hospitalized patients by exploring perspectives of the interprofessional health care team. A qualitative design was used to capture insights from clinicians across disciplines in a large midwestern academic medical center. Four homogenous semistructured focus groups and three individual interviews involving a total of 20 clinicians were conducted between October 2013 and March 2014. Audio-recorded data were transcribed and analyzed using inductive qualitative analysis. Two primary themes emerged from participants regarding the sustainability of an evidence-based fall prevention program: communication patterns within the interprofessional health care team and influences of hospital organizational practices and elements. Several subthemes also emerged. Participants gave nursing staff primary responsibility for fall risk assessment and prevention. Individual professional perceptions and practices, as well as organizational characteristics, affect the sustainability of evidence-based fall prevention practices. While all team members recognized patient falls as a significant quality and safety issue, most believed that direct care nurses hold primary responsibility for leading fall prevention efforts. The data support the importance of effective interprofessional team communication and organizational practices in sustaining an evidence-based fall prevention program across inpatient units. Furthermore, the data call into question the wisdom in labeling quality indicators as "nursing sensitive"; the evidence indicates that a team approach is best.

    Urban ecology is emerging as an integrative science that explores the interactions of people and biodiversity in cities. Interdisciplinary research requires the creation of new tools that allow the investigation of relations between people and biodiversity. It has been established that access to green spaces or nature benefits city dwellers, but the role of species diversity in providing psychological benefits remains poorly studied. We developed a user-friendly 3-dimensional computer program (Virtual Garden [www.tinyurl.com/3DVirtualGarden]) that allows people to design their own public or private green spaces with 95 biotic and abiotic features. Virtual Garden allows researchers to explore what elements of biodiversity people would like to have in their nearby green spaces while accounting for other functions that people value in urban green spaces. In 2011, 732 participants used our Virtual Garden program to design their ideal small public garden. On average gardens contained 5 different animals, 8 flowers, and 5 woody plant species. Although the mathematical distribution of flower and woody plant richness (i.e., number of species per garden) appeared to be similar to what would be expected by random selection of features, 30% of participants did not place any animal species in their gardens. Among those who placed animals in their gardens, 94% selected colorful species (e.g., ladybug [Coccinella septempunctata], Great Tit [Parus major], and goldfish), 53% selected herptiles or large mammals, and 67% selected non-native species. Older participants with a higher level of education and participants with a greater concern for nature designed gardens with relatively higher species richness and more native species. If cities are to be planned for the mutual benefit of people and biodiversity and to provide people meaningful experiences with urban nature, it is important to investigate people's relations with biodiversity further.

    In the Summer of 2016 we conducted a 10-week pilot Research Experience for Undergraduates (REU) program aimed at increasing the participation of underrepresented minority undergraduate students in research using data from the Sloan Digital Sky Survey (SDSS). This program utilized a distributed REU model, whereby students worked with SDSS scientists on exciting research projects while serving as members of a geographically distributed research community. The format of this REU is similar to that of the SDSS collaboration itself, and since this collaboration structure has become a model for the next generation of large scale astronomical surveys, the students participating in the SDSS REU received early exposure and familiarity with this approach to collaborative scientific research. The SDSS REU also provided the participants with a low-risk opportunity to audition for graduate schools and to explore opportunities afforded by a career as a research scientist. The six student participants were placed at SDSS REU host sites at the Center for Astrophysics at Harvard University, University of Wisconsin-Madison, Vanderbilt University, and the University of Portsmouth. Their research projects covered a broad range of topics related to stars, galaxies, and quasars, all making use of SDSS data. At the start of the summer the REU students participated in a week-long Boot Camp at NMSU, which served as a program orientation, an introduction to skills relevant to their research projects, and an opportunity for team-building and cohort-forming. To foster a sense of community among our distributed students throughout the summer, we conducted a weekly online meeting for all students in the program via virtual meeting tools. These virtual group meetings served two purposes: as a weekly check-in to find out how their projects were progressing, and to conduct professional development seminars on topics of interest and relevance to the REU participants. We discuss the outcomes of this

    Full Text Available Incentives can promote adult wellness. We sought to examine whether incentives might help overcome barriers to engagement in child weight management programs and the ideal value, type and recipient of incentives. In 2017, we conducted semi-structured phone interviews with parents of children ≤17 years old, formerly or currently affected by obesity, who had (n = 11 or had never (n = 12 participated in family-based behavioral treatment (FBT for obesity. Interviews explored the range and type of incentives families would be willing to accept. Interview transcripts were coded and data were analyzed using a thematic analysis. We found that some parents were skeptical about receiving cash incentives. However, once treatment-related costs were identified, some became more interested in reimbursement for out of pocket expenditures. Most parents felt up to $100/month would be adequate and that incentives should be tied to changing behaviors, not BMI. Some interviewees expressed preferences for non-cash incentives (e.g. a gift card over cash incentives. Parents were willing to share incentives with adolescents, up to $50/month, but there was concern about incentives affecting a child's intrinsic motivation for behavior change. All parents acknowledged that moderate incentives alone couldn't overcome the realities of structural and familial barriers to engaging in weight management programs. In summary, we identified aspects of an incentive program to promote engagement in FBT that would be desirable and feasible to implement. Future quantitative work can reveal the value and structure of incentives that are effective for improving obesogenic health behaviors and outcomes.

  7. A critical exploration of science doctoral programs: Counterstories from underrepresented women of color

    Science.gov (United States)

    Bancroft, Senetta F.

    Most studies exploring the experiences of underrepresented doctoral students of color in science fields focus on their socialization into predominantly white institutions. While the socialization process is fundamental to doctoral success and consequently deserves attention, it is critical to inquire into how the widespread and lasting perception of people of color as socioculturally deficient shapes underrepresented students` socialization into science doctoral programs. Further, the existing research literature and educational policies addressing the persistent underrepresentation of students of color in science doctorates remain fixated on increasing racial diversity for U.S. economic security rather than racial equity. In view of the limitation of existing research literature, in this study, drawing from critical race theories, fictive-kinship, and forms of capital, I use counterstorytelling to recast racial inequities in the education of science doctorates as a problem of social justice, not as an issue of the students' sociocultural deficits or as a matter of economic security. Through interviews I examined the experiences, from elementary school to current careers, of three women of color who were science doctoral students. Participants' counterstories revealed institutionalized racism embedded in doctoral programs exploited their identities and dismissed their lived experiences, thereby, relegating them to outsiders-within academe. This marginalization precluded the inclusive socialization of participants into their doctoral programs and ultimately set up barriers to their pursuit of scientific careers. This study divulges the academic and career consequences of the sustained privilege disparities between underrepresented students of color's experience and the experiences of their white and Asian counterparts. In light of the participants' experiences, I recommend that, in order to change the existing policy of socially integrating students into oppressive

    The Canadian program for the development and evaluation of processes and technology for the separation and containment of radioactive species in off-gases is directed towards the following specific aspects: 1) assessment of available treatment technology and evaluation of future clean-up requirements; 2) development and engineering evaluation, under realistic conditions, of promising new processes that would be inherently simpler and safer; and 3) specification of off-gas emission control systems for future nuclear facilities based on the most favourable technology. The program is being carried out by Atomic Energy of Canada Limited in collaboration with the electrical utility, Ontario Hydro, and selected Canadian universities. A brief description is presented of methods for removing tritium and carbon-14 from the moderator systems of CANDU power reactors, methods for removing iodine from the off-gases of a molybdenum-99 production facility at the Chalk River Nuclear Laboratories, and procedures for monitoring the off-gas effluent composition in the Thorium Fuel Reprocessing Experiment (TFRE) facility at the Whiteshell Nuclear Research Establishment

  9. Exploring the architectural trade space of NASAs Space Communication and Navigation Program

    Sanchez, M.; Selva, D.; Cameron, B.; Crawley, E.; Seas, A.; Seery, B.

    NASAs Space Communication and Navigation (SCaN) Program is responsible for providing communication and navigation services to space missions and other users in and beyond low Earth orbit. The current SCaN architecture consists of three independent networks: the Space Network (SN), which contains the TDRS relay satellites in GEO; the Near Earth Network (NEN), which consists of several NASA owned and commercially operated ground stations; and the Deep Space Network (DSN), with three ground stations in Goldstone, Madrid, and Canberra. The first task of this study is the stakeholder analysis. The goal of the stakeholder analysis is to identify the main stakeholders of the SCaN system and their needs. Twenty-one main groups of stakeholders have been identified and put on a stakeholder map. Their needs are currently being elicited by means of interviews and an extensive literature review. The data will then be analyzed by applying Cameron and Crawley's stakeholder analysis theory, with a view to highlighting dominant needs and conflicting needs. The second task of this study is the architectural tradespace exploration of the next generation TDRSS. The space of possible architectures for SCaN is represented by a set of architectural decisions, each of which has a discrete set of options. A computational tool is used to automatically synthesize a very large number of possible architectures by enumerating different combinations of decisions and options. The same tool contains models to evaluate the architectures in terms of performance and cost. The performance model uses the stakeholder needs and requirements identified in the previous steps as inputs, and it is based in the VASSAR methodology presented in a companion paper. This paper summarizes the current status of the MIT SCaN architecture study. It starts by motivating the need to perform tradespace exploration studies in the context of relay data systems through a description of the history NASA's space communicati

    The application of GC×GC-FID and GC×GC-MS for the chemical analysis and profiling of neat white spirit is explored and the benefit of the enhanced peak capacity offered by comprehensive two-dimensional gas chromatography is demonstrated. An extensive sampling exercise was conducted throughout The Netherlands and the production and logistics in terms of bottling and distribution of white spirits were studied. An exploratory approach based on target-peak tables and principal component analysis was employed to study the brand-to-brand differences and production variations over time. Despite the complex chemical composition of white spirit samples this study shows that chemical variation during productions is actually quite limited. Hence care has to be taken with the chemical comparison for forensic purposes. Although some clustering was noticed on brand level, the large scale production process leads to a very consistent composition across stores and brands. However, because of the broad specifications of this commodity product, substantial chemical variation was found over time. This temporal discrimination could be of forensic value when considering white spirits supplies in individual households. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    In May 1993, Public Service Electric and Gas (PSE&G), the largest investor-owned utility in New Jersey, initiated the Standard Offer program, an innovative approach to acquiring demand-side management (DSM) resources. In this program, PSE&G offers longterm contracts with standard terms and conditions to project sponsors, either customers or third-party energy service companies (ESCOs), on a first-come, first-serve basis to fill a resource block. The design includes posted, time-differentiated prices which are paid for energy savings that will be verified over the contract term (5, 10, or 15 years) based on a statewide measurement and verification (M&V) protocol. The design of the Standard Offer differs significantly from DSM bidding programs in several respects. The eligibility requirements and posted prices allow ESCOs and other energy service providers to market and develop projects among customers with few constraints on acceptable end use efficiency technologies. In contrast, in DSM bidding, ESCOs typically submit bids without final commitments from customers and the utility selects a limited number of winning bidders who often agree to deliver a pre-specified mix of savings from various end uses in targeted markets. The major objectives of the LBNL evaluation were to assess market response and customer satisfaction; analyze program costs and cost-effectiveness; review and evaluate the utility`s administration and delivery of the program; examine the role of PSE&G`s energy services subsidiary (PSCRC) in the program and the effect of its involvement on the development of the energy services industry in New Jersey; and discuss the potential applicability of the Standard Offer concept given current trends in the electricity industry (i.e., increasing competition and the prospect of industry restructuring).

  13. Obedience to compliance programs and independence for electricity and natural gas system operators. 2009 report

    International Nuclear Information System (INIS)

    2009-12-01

    In France, system operators belong to groups that also conduct business in the energy sector, in fields governed by competition rules. They could therefore be tempted to use their privileged position to their group's benefit, which would disadvantage end consumers. Non-discriminatory access to electricity and gas transmission and distribution networks is at the core of the market opening to competition approach implemented by the European Union since the end of the 1990's. EU and national enactments in force highlight two tools to ensure nondiscrimination: compliance programmes and independence of system operators with regard to their parent companies. Firstly, compliance programs contain measures taken to ensure that discrimination is completely excluded and that their application is subject to appropriate monitoring. Secondly, system operator independence plays a part in preventing discrimination against competitors with other business activities (generation, supply, etc.) within the same group. In application of these enactments, every electricity or natural gas transmission or distribution system operator serving more than 100,000 customers provided CRE, the Energy Regulatory Commission, with their annual reports on the application of their compliance programs. This document is CRE's 2009 report about compliance programmes and independence of electricity and natural gas system operators. Its content can be summarized as follows: 1 - system operator independence serving consumers: Non-discriminatory access to networks is essential for the development of competitive markets, System operator compliance programs and independence act as a guarantee of nondiscrimination, The legal context in which these issues are addressed is set to change in the near future; 2 - A high level of obedience to compliance programs: The continued efforts of system operators prevent discrimination, CR E has assessed distribution system operators by means of a mystery

    1987-07-01

    The innovative US calculation method for natural gas real gas factors is applicable to great pressure and temperature ranges and does not involve any restrictions as to the quality of natural gas. The results obtained for natural gas coming from Northern Germany or for imported natural gas are well consistent with actual measuring results. The model can therefore be applied as a rule for computing in a new technical recommendation and determine real gas factors whenever they are relevant to trading. The respective calculations must be preceded by a complete analysis characterizing the quality of gases. However, the new method allows for the alternative calculation of real gas factors on the basis of a small number of easily measurable factors (for example H/sub 0/, d, CO/sub 2/). This quality seams to be all the more attractive as it allows for an automatic translation of parametric sets at changing gas qualities which for the first time can manage without an expensive online gas chromatography or density translators, respectively.

    Despite its popularity, the effectiveness of audit and feedback in support quality improvement efforts is mixed. While audit and feedback-related research efforts have investigated issues relating to feedback design and delivery, little attention has been directed towards factors which motivate interest and engagement with feedback interventions. This study explored the motivating factors that drove primary care teams to participate in a voluntary audit and feedback initiative. Interviews were conducted with leaders of primary care teams who had participated in at least one iteration of the audit and feedback program. This intervention was developed by an organization which advocates for high-quality, team-based primary care in Ontario, Canada. Interview transcripts were coded using the Consolidated Framework for Implementation Research and the resulting framework was analyzed inductively to generate key themes. Interviews were completed with 25 individuals from 18 primary care teams across Ontario. The majority were Executive Directors (14), Physician leaders (3) and support staff for Quality Improvement (4). A range of motivations for participating in the audit and feedback program beyond quality improvement were emphasized. Primarily, informants believed that the program would eventually become a best-in-class audit and feedback initiative. This reflected concerns regarding existing initiatives in terms of the intervention components and intentions as well as the perception that an initiative by primary care, for primary care would better reflect their own goals and better support desired patient outcomes. Key enablers included perceived obligations to engage and provision of support for the work involved. No teams cited an evidence base for A&F as a motivating factor for participation. A range of motivating factors, beyond quality improvement, contributed to participation in the audit and feedback program. Findings from this study highlight that efforts to

    Indonesia depends heavily on revenues from the export of LNG and oil, the availability of which appears to be decreasing. It is therefore making a strong effort to accelerate development of a domestic natural gas industry. A high priority has been given to the conversion of power plants and city gas systems, including local industries and commercial facilities, from liquid fuels to natural gas. This will release more oil for export, help to meet the objectives of Repelita V, and provide substantial environmental benefits. The World Bank recently provided loans to the Indonesian Government for two projects that are aimed at substituting natural gas for oil and manufactured gas in domestic markets. One project involves expansion of the gas distribution systems of Indonesia's natural gas utility (PGN) in three cities: Jakarta and Bogor in Java, and Medan in Sumatra. Approximately 350 new industrial, 800 new commercial, and 12,700 new residential natural gas customers are expected from this project. Incremental gas sales are projected to be about 48.1 million CF/d when the project is completed in 1992. The project also includes training programs for PGN staff and an energy pricing policy study to be carried out by Indonesia's Ministry of Mines and Energy. The second project involves expansion of the supply of natural gas for Surabaya and twelve other towns in its vicinity in East Java, and further expansion of Medan's supply system. The gas for Surabaya will be used for about 400 industrial and 150 commercial customers, and 3,600 households. The additional gas supply for Medan will be used for two power plants operated by the state electric utility, PLN. Incremental natural gas sales from this project are projected to be 68 million CF/d when it is

    Natural gas, which is comprised mostly of methane, is one of our most abundant natural resources, both in the U.S. and world wide. In the United States alone, recoverable natural gas resources are several times its current estimate of reserves, 166 trillion cubic feet (TCF). Unfortunately, many of these resources are located offshore or in remote areas. High transportation costs, or complete lack of any transportation mechanism, prohibits extensive use of this 'stranded' natural resource. To overcome this limitation, the U.S. Department of Energy's (DOE) Federal Energy Technology Center (FETC) has developed a highly diversified gas-to-liquids research program to evaluate, promote and develop processes that convert natural gas into higher value products (i.e., liquid fuels) which will offset the high transportation costs and allow use of this untapped, environmentally friendly resource. By advancing technologies to convert unmarketable gas resources into valuable products, cooperative efforts between DOE and industry could yield the following benefits by 20 10: (1) Our shortfall in domestic production of oil will be reduced by 200,000 to 500,000 barrels per day of high quality transportation fuel made from Alaska's North Slope gas resources; (2) Advanced gas-to-liquids conversion technology that yields ultra clean burning diesel fuels that meet the most stringent emissions requirements, at costs competitive with those of comparable fuels made from crude oils, will be utilized; and (3) Small-scale gas-to-liquids technology for both natural gas liquefaction and chemical conversion to higher hydrocarbon liquids will provide an economic and environmentally sound option for utilization of the associated gas of remote offshore oil reservoirs, and also for onshore gas reservoirs without pipeline access. In summary, development of efficient gas conversion technologies will enhance U.S. energy security, reduce dependence on oil imports and strengthen the economic

    An experimental, inquiry-based physical science curriculum for undergraduate, pre-service K-8 teachers is under development at the Catholic University of America in collaboration with the Solar Physics Branch of the Naval Research Laboratory and NASA's Sun-Earth Connection missions. This is a progress report. The current, stunningly successful exploratory phase in Sun-Earth Connection (SEC) physics, sparked by SOHO, Yohkoh, TRACE, and other International Solar Terrestrial Physics (ISTP) and Living With a Star (LWS) programs, has provided dynamic, visually intuitive data that can be used for teaching basic physical concepts such as the properties of gravitational and electromagnetic fields which are manifest in beautiful imagery of the astrophysical plasmas of the solar atmosphere and Earth's auroras. Through a team approach capitalizing on the combined expertise of the Catholic University's departments of Education and Physics and of NRL solar researchers deeply involved in SEC missions we have laid out a program that will teach non-science-major undergraduates a very limited number of physical science concepts but in such a way as to develop for each one both a formal understanding and an intuitive grasp that will instill confidence, spark interest and scientific curiosity and, ideally, inspire a habit of lifetime inquiry and professional growth. A three-semester sequence is planned. The first semester will be required of incoming Education freshmen. The second and third semesters will be of such a level as to satisfy the one-year science requirement for non-science majors in the College of Arts and Sciences. The approach as adopted will integrate physics content and educational methods, with each concept introduced through inquiry-based, hands-on investigation using methods and materials directly applicable to K-8 teaching situations (Exploration Phase). The topic is further developed through discussion, demonstration and lecture, introducing such mathematical

    Full Text Available Abstract Background The natural assimilation of the process through which health partners sustain long-term relationships is a key issue in maintaining social well-being, reducing health risk factors, and sustaining public health programs. One global initiative in building effective healthcare systems is public-private partnerships (PPPs. This study elucidates the proposed key performance indicators initiated by the Ministry of Health of Saudi Arabia based on the projections of the government, known as Vision 2030, from the perspective of health risk factors. Methods Through an inductive content analysis, this study assessed primary and secondary data in relation to the Saudi National Transformation Program (NTP. To identify the institutions that played a role in formulating the new Saudi Healthcare System, health policies, regulations, and reports published between 1996 and 2016 were categorized. After ranking the risk factors, the investigator selected 13 healthcare professionals in four focus group interviews to insightfully explore the challenges that the NTP faces from a health risk perspective. Thus, the study employed qualitative data gathered through focus group interviews with key figures as well as data extracted from written sources to identify distinct but interrelated partnerships practiced within risk management. Results A methodological overview of NTP priority and implementation offered practical guidance in the healthcare context. The five critical factors in maintaining successful and sustainable PPPs were (1 trustworthiness, (2 technological capability, (3 patient-centeredness, (4 competence, and (5 flexibility. Concession on primary and secondary healthcare services might be a good option based on the literature review and considering its popularity in other countries. A high outcome-based risk of PPPs was found as the most commonly shared perspective in risk management. Conclusions Although the impact of the NTP rise has yet

    The application rate of nitrogen fertilizer was believed to dramatically influence greenhouse gas (GHG) emissions from paddy fields. Thus, providing a suitable nitrogen fertilization rate to ensure rice yields, reducing GHG emissions and exploring emission behavior are important issues for field management. In this paper, a two year experiment with six rates (0, 75, 150, 225, 300, 375 kg N/ha) of nitrogen fertilizer application was designed to examine GHG emissions by measuring carbon dioxide (CO{sub 2}), methane (CH{sub 4}), nitrous oxide (N{sub 2}O) flux and their cumulative global warming potential (GWP) from paddy fields in Hangzhou, Zhejiang in 2013 and 2014. The results indicated that the GWP and rice yields increased with an increasing application rate of nitrogen fertilizer. Emission peaks of CH{sub 4} mainly appeared at the vegetative phase, and emission peaks of CO{sub 2}, and N{sub 2}O mainly appeared at reproductive phase of rice growth. The CO{sub 2} flux was significantly correlated with soil temperature, while the CH{sub 4} flux was influenced by logging water remaining period and N{sub 2}O flux was significantly associated with nitrogen application rates. This study showed that 225 kg N/ha was a suitable nitrogen fertilizer rate to minimize GHG emissions with low yield-scaled emissions of 3.69 (in 2013) and 2.23 (in 2014) kg CO{sub 2}-eq/kg rice yield as well as to ensure rice yields remained at a relatively high level of 8.89 t/ha in paddy fields. - Highlights: • Exploiting co-benefits of rice yield and reduction of greenhouse gas emission. • Global warming potential and rice yield increased with nitrogen fertilizer rate up. • Emission peaks of CH{sub 4,} CO{sub 2} and N{sub 2}O appeared at vegetative and reproductive phase. • 225 kg N/ha rate benefits both rice yields and GWP reduction.

    2016-06-01

    Full Text Available Global climate change and the accelerating depletion of natural resources have contributed to increase discussions about the role of private enterprises in reversing negative environmental trends. Rather than focusing on profit maximization, policy makers and consumers pressure groups expect firms to meet a triple-bottom line of economic, environmental and social value creation. Hence sustainable entrepreneurship has received recently increasing interest as a phenomenon and a research topic. More recently, the concept of sustainability has been taken seriously in the Italian wine industry. The organizational challenge for entrepreneurship is to better integrate social and environmental performance into the economic business logic. The aim of this manuscript is to illustrate, through a descriptive approach, the adaptation of the wine industry to the new scenario of sustainable entrepreneurship. To reach this goal we carried out an explorative analysis of 3 Sicilian wineries involved in the SOStain program, which aims at the improvement of sustainability in the wine industry. The findings of the analysis show the existence of sustainability-driven entrepreneurship, in which the wineries undertake to behave ethically and contribute to economic development while improving the quality of life for the workforce, their families, the local and global community as well as future generations.

    Poland is one of few European countries undertaking innovative research towards effective exploration of hydrocarbons form shale deposits. With regard for strict geological conditions, which occur during hydraulic fracturing, it is required to apply ceramic proppants enhancing extraction of shale gas. Ceramic proppants are granules (16/30 - 70/120 Mesh) classified as propping agents. These granules located in the newly created fissures (due to injected high pressure fluid) in the shale rock, act as a prop, what enables gas flow up the well. It occurs if the proppants can resist high stress of the closing fractures. Commonly applied proppants are quartz sands used only for shallow reservoirs and fissile shales (in the USA). Whereas, the ceramic granules are proper for extraction of gas on the high depths at hard geomechanical conditions (in Europe) to increase output even by 30 - 50%. In comparison to other propping materials, this kind of proppants predominate with mechanical strength, smoother surface, lower solubility in acids and also high stability in water. Such parameters can be available through proper raw materials selection to further proppants production. The Polish ceramic proppants are produced from natural resources as kaolin, bauxite and white clay mixed with water and binders. Afterwards, the slurries are subjected to granulation in a mechanical granulator and sintered at high temperatures (1200 - 1550°C). Taking into consideration presence of geomechanical barriers, that prevent fracture propagation beyond shale formations, it is crucial to determine quality of applied natural deposits. Next step is to optimize the proppants production and select the best kind of granules, what was the aim of this research. Utility of the raw materials was estimated on basis of their particle size distribution, bulk density, specific surface area (BET) and thermal analysis (thermogravimetry). Morphology and shape were determined by Scanning Electron Microscopy (SEM

    Massive hydraulic fracture mapping field experiments continued in FY 77 with Sandia participating in fractures with Gas Producing Enterprises, Amoco, Shell, and Conoco. The surface electrical potential system has demonstrated that the fracture orientation can be determined to within +- 5/sup 0/ and has clearly shown that most fractures are asymmetrical. This system has been completely documented and has had wide exposure to the industry providing for the transfer of its technology. Improvements in the electrical system, its analytical model and the development of new systems for fracture diagnostics was also continuing. Hydraulic and explosive fracturing experiments have been conducted adjacent to an existing tunnel complex at DOE's Nevada Test Site and have been directly observed by subsequent mineback activities. Evaluation of a proppant distribution experiment has revealed a very complex fracture system which differed significantly from design; additional in situ stress and material property measurements are being made to quantify observed behavior. An experiment has been designed and conducted which will examine hydraulic fracture behavior at a geologic interface between formations with significantly different moduli, Poisson's ratios and porosities; mineback evaluation will occur next year. In conjunction wth a nuclear containment program, the stresses surrounding a contained explosive detonation have been examined. A 256 lb TNT detonation produced no radial fractures extending from the main cavity, but gases escaping down a borehole did create a 30 x 75 ft fracture in a region of reduced overburden stress caused by the explosion.

    Full Text Available A production system analysis was made for the well Šandrovac-136 equipped with a continuous gas lift. The analysis was based on the test data which served as the foundation for creating a production well model in computer program ‘PROSPER’ (Version 10.3, License 2681. The importance of the measured data in well modeling is accuracy and reliability in predicting future developments of the production system. The model design can be divided in six steps among which the most important are: calculation of the IPR curve, calculation of the gas lift system and matching of VLP and IPR curves based on the well testing. The aim of the VLP/IPR matching is to choose an appropriate method for calculating the pressure drop gradient by applying the nonlinear regression method, which results in the system working point adjusted to the measured data. This model was applied in sensitivity analysis of the well, in which three key variables are selected to predict their effect on future system changes, primarily on changes of the production and bottom dynamic pressure (the paper is published in Croatian.

  6. Analyzing the greenhouse gas impact potential of smallholder development actions across a global food security program

    This article analyses the greenhouse gas (GHG) impact potential of improved management practices and technologies for smallholder agriculture promoted under a global food security development program. Under ‘business-as-usual’ development, global studies on the future of agriculture to 2050 project considerable increases in total food production and cultivated area. Conventional cropland intensification and conversion of natural vegetation typically result in increased GHG emissions and loss of carbon stocks. There is a strong need to understand the potential greenhouse gas impacts of agricultural development programs intended to achieve large-scale change, and to identify pathways of smallholder agricultural development that can achieve food security and agricultural production growth without drastic increases in GHG emissions. In an analysis of 134 crop and livestock production systems in 15 countries with reported impacts on 4.8 million ha, improved management practices and technologies by smallholder farmers significantly reduce GHG emission intensity of agricultural production, increase yields and reduce post-harvest losses, while either decreasing or only moderately increasing net GHG emissions per area. Investments in both production and post-harvest stages meaningfully reduced GHG emission intensity, contributing to low emission development. We present average impacts on net GHG emissions per hectare and GHG emission intensity, while not providing detailed statistics of GHG impacts at scale that are associated to additional uncertainties. While reported improvements in smallholder systems effectively reduce future GHG emissions compared to business-as-usual development, these contributions are insufficient to significantly reduce net GHG emission in agriculture beyond current levels, particularly if future agricultural production grows at projected rates.

    2011-01-01

    This article presents the evaluation of the natural gas program for vehicles applied in Metropolitan Area of the Aburra Valley. By using the Cost- Benefit Analysis method, four cost variables were identified: private, fiscal, gas tax, and conversion tax; and three types of benefits: private, fiscal and social. For the environmental social benefit estimation the benefit transfer technique was employed, carrying out meta-analysis function estimation. The cost-benefit net outcome is positive and favors the program application in the study site; in real terms the total profits are about COP$ 803265 million for the complete eight year period it took place (2001- 2008).

    By the analysis and contrast of existing form of gas-uranium, correlation between gas-uranium and organic matter, distribution characteristics and control factors of mineralization (bosom) in the sedimentary formation of shale gas and black uranium bearing rock series, the authors come to the conclusion that: in the carbonate-siliceous-pelitic of black rock series the uranium and gas (oil) is essentially equipped coenosarc of the same homology, syngenetic, reservoir. They are ore source beds of carbonate-siliceous-pelitic rock uranium deposit, and also the hydrocarbon source beds in which the shale gas form. In black shales, uranium largely exist in the form of the ion adsorption (acetyl ion/uranyl ion). Under fracturing conditions, we can realize desorption mode of chemical solvents of adding acid or alkali, and extract uranium by concentrating liquid (the same as in-situ mimng technology). Therefore, the fracturing technology (clear water fracturing techniques, repeat fracturing techniques, synchronization fracturing techniques, multistage fracturing techniques, network fracturing techniques and so on) of shale gas exploitation lay a foundation for black shale uranium-gas joint development. The mature and corollary use of fracturing techniques and in-situ mining technology of low grade uranium will undoubtedly further increase the industrial resource extent of uranium and gas, improve guaranteeing degree of resource, reform of promote energy production structure and provide a large number of economical and effective clean energy.

    2013-10-01

    Full Text Available Autobiographies depict with words life stories, personal experiences, and perceptions that allow researchers to deeply understand the way people see life, reflect, and construct meaning out of experiences. This article aims at describing the contributions of autobiographies as valuable resources in qualitative research when exploring people’s beliefs, personal knowledge, and changes as a result of experience and learning. This is all based on a research project carried out at a Colombian public university, where students from the undergraduate English teaching program wrote their language learning stories which were used as an instrument to garner data. The project also aims at demonstrating how these narratives exhibit human activity and diverse events that may have a significant effect on the epistemologies and methodologies of teacher education.Las autobiografías perfilan con palabras las historias de vida, experiencias personales y percepciones que brindan a los investigadores una profunda comprensión de la manera como las personas ven la vida, reflexionan y construyen significado a partir de esas experiencias. Este artículo tiene como objetivo describir las contribuciones de las autobiografías como recursos valiosos en la investigación cualitativa por cuanto son un medio para explorar las creencias, el conocimiento personal y los cambios en los individuos como resultado de la experiencia y el aprendizaje. El presente trabajo se basa en una investigación realizada en una universidad pública colombiana, en la que estudiantes de la Licenciatura en Inglés narraron sus historias sobre el aprendizaje de la lengua; narraciones que fueron usadas como instrumentos para la recolección de información. Adicionalmente, se busca demostrar cómo dichas narrativas describen la actividad humana y diversos eventos que pudiesen tener un efecto significativo en la construcción epistemológica y metodológica en la formación de docentes.

    2018-01-01

    Understanding the effect of cis-regulatory elements (CRE) and clusters of CREs, which are called cis-regulatory modules (CRM), in eukaryotic gene expression is a challenge of computational biology. We developed two programs that allow simple, fast and reliable analysis of candidate CREs and CRMs that may affect specific gene expression and that determine positional features between individual CREs within a CRM. The first program, "Exploration of Distinctive CREs and CRMs" (EDCC), correlates candidate CREs and CRMs with specific gene expression patterns. For pairs of CREs, EDCC also determines positional preferences of the single CREs in relation to each other and to the transcriptional start site. The second program, "CRM Network Generator" (CNG), prioritizes these positional preferences using a neural network and thus allows unbiased rating of the positional preferences that were determined by EDCC. We tested these programs with data from a microarray study of circadian gene expression in Arabidopsis thaliana. Analyzing more than 1.5 million pairwise CRE combinations, we found 22 candidate combinations, of which several contained known clock promoter elements together with elements that had not been identified as relevant to circadian gene expression before. CNG analysis further identified positional preferences of these CRE pairs, hinting at positional information that may be relevant for circadian gene expression. Future wet lab experiments will have to determine which of these combinations confer daytime specific circadian gene expression.

    Abdel-Razek, Y.A; Bakhit, A.F

    2009-01-01

    Ten well-located monitoring stations along El-Burullus beach were chosen to measure radon gas concentrations in the beach sands below surface, and γ-ray intensities at 10 cm above the surface. These stations were chosen to represent apparent concentrations of the black sands. Sand samples were collected from the different stations and analyzed to study the relation between the concentrations of the heavy minerals and the measured radon concentrations or the measured γ-ray intensities at these stations. It was found that radon gas concentrations measured at 6:00 Pm were about 2.82 times those measured at 1 :00 Pm due to diurnal variation of temperature. Measurements of radon gas concentrations inside the beach sands are found to be more reliable in qualitative exploration of black sands than the measurements of γ-ray intensities above the shore sands due to the random arrangement of the layers of these sands below surface

    Full Text Available Recently, a one-time cohort of graduate-level social work students completed a unique MSW program. The program was delivered in partnership between the Faculty of Social Work, University of Calgary and Blue Quills First Nations College and, of the twenty four graduates; twenty-one were of First Nations or Me´tis ancestry. The program honored traditional knowledge and ways of learning combined with a critical analysis of Western perspectives of social work knowledge. Strong fiscal resources enabled the program to establish a formal support network for the students and to support the development of Indigenous curriculum and programming that encouraged success for the students. The program was fundamentally different than urban on-campus programs while still maintaining graduate level accreditation requirements. This analysis of the program required the use of Indigenous Research Methodology to collect and create an understanding of the program. Instructors commented on the centered, empowered, balanced, and congruent students. The formal and informal, concrete and invisible supports to the students ensured the success of this program and this cohort of students. As one student commented, the program started in ceremony, ended in ceremony, and could not fail within the context ceremony.

    The US Geological Survey (USGS) uranium-thorium program is continuing to emphasize multidisciplinary studies to define the settings and habitats of uranium deposits and to elucidate the processes by which the ore deposits formed. As with the uranium scene generally, some uncertainty characterizes the program's transition from FY 1980 to FY 1981. As of the beginning of the new fiscal year, a cut of 15% in base funding of the USGS uranium program has been effected by Congress. Such a cut parallels the major curtailment of the NURE program. The USGS in FY 1980 completed almost all of its commitment to the NURE program quadrangle-evaluation work, and only a relatively modest continuing involvement in the NURE world-class and intermediate-grade studies remains for FY 1981. Objectives and program scope, noteworthy results of FY 1980 research, and program activities for FY 1981 are presented in this report

    To ascertain how program leaders in family medicine characterize success in family medicine maternity care education and determine which factors influence the success of training programs. Qualitative research using semistructured telephone interviews. Purposive sample of 6 family medicine programs from 5 Canadian provinces. Eighteen departmental leaders and program directors. Semistructured telephone interviews were conducted with program leaders in family medicine maternity care. Departmental leaders identified maternity care programs deemed to be "successful." Interviews were audiorecorded and transcribed verbatim. Team members conducted thematic analysis. Participants considered their education programs to be successful in family medicine maternity care if residents achieved competency in intrapartum care, if graduates planned to include intrapartum care in their practices, and if their education programs were able to recruit and retain family medicine maternity care faculty. Five key factors were deemed to be critical to a program's success in family medicine maternity care: adequate clinical exposure, the presence of strong family medicine role models, a family medicine-friendly hospital environment, support for the education program from multiple sources, and a dedicated and supportive community of family medicine maternity care providers. Training programs wishing to achieve greater success in family medicine maternity care education should employ a multifaceted strategy that considers all 5 of the interdependent factors uncovered in our research. By paying particular attention to the informal processes that connect these factors, program leaders can preserve the possibility that family medicine residents will graduate with the competence and confidence to practise full-scope maternity care.

    When drilling through gas hydrate bearing formations, the energy supplied by virtue of the drilling process may lead to a destabilization of the hydrates surrounding the wellbore. Therefore, as the number of oil and gas fields being development in deepwater and onshore arctic environments increases, greater emphasis should be placed on quantifying the risks, gas hydrates pose to drilling operations. The qualification of these risks requires a comprehensive understanding of gas hydrate-formation and dissociation as a result of drilling induced processes. To develop the required understanding of gas hydrat formation and dissociation, the authors conducted laboratory experiments by using a micro-drilling system, to study the dissociation rates of methane hydrates contained in a tank reactor. The test facility used is a development of China University of Geosciences. The rates of methane hydrate formation and dissociation in the tank reactor were measured at steady-state conditions at pressures ranging from 0.1 to 25 MPa and temperatures ranging from -5 to 20 C. The experimental results show that the rate of hydrate formation is strongly influenced by the fluid system used to form the hydrates, pressure and temperature, with the influence of the temperature on methane hydrate dissociation being stronger than that of the pressure. Drilling speed, drilling fluids and hydrate dissociation inhibitors were also shown to influence hydrate dissociation rate. The derived results have been used to predict hydrate drilling stability for several drilling fluid systems.

    2014-07-01

    Full Text Available The difficulty of learning to program has long been identified amongst novices. This study explored the benefits of teaching a problem solving strategy by comparing students’ perceptions and attitudes towards problem solving before and after the strategy was implemented in secondary schools. Based on self-efficacy theory, students’ problem solving self-efficacy as well as teachers’ self-efficacy were investigated, showing that both students’ and teachers’ self-efficacy may have benefited from the explicit instruction. This would imply that teaching problem solving explicitly should be encouraged to increase self-efficacy to program.

  2. Crude costs: a framework for a full-cost accounting analysis of oil and gas exploration off Cape Breton, Nova Scotia

    2001-12-01

    Defined as the total quantity of all goods and services produced and the total money earned and spent, the Gross Domestic Product (GDP) is a measure used to determine how well an economy is doing. For its part, the Genuine Progress Index (GPI) measures 26 variables and was first developed in 1995. In Nova Scotia, a set of 20 social, economic and environmental indicators are examined to obtain a better picture of the well-being of the region and determine if the development is sustainable over time. The authors explained their approach based on the use of GPI analysis to assist decision makers in identifying the real costs and benefits of different options applied to the oil and gas exploration situation off Cape Breton, Nova Scotia. The document is divided into five parts as follows: (1) Part 1: introduction, (2) Part 2: natural capital and the impacts of oil and gas development, (3) Part 3: social capital and the economic value of fishing and tourism, (4) Part 4: the real cost of oil and gas, and (5) Part 5: recommendations. Some of the recommendations call for the further study of cumulative and sub-lethal effects from petroleum development, the establishment of Marine Protected Areas preceded by a moratorium on oil and gas exploration in the Southern Gulf of St. Lawrence and Sydney Bight areas until the establishment of the Areas is made, and that future environmental assessments concerning oil and gas development to address the impacts on species and ecosystems as a whole. 209 refs., 11 tabs., 4 figs

    1967-08-01

    This report on the natural gas industry of Canada includes: composition and uses of natural gas, production statistics, exploration and development, reserve estimates, natural gas processing, transportation, and marketing. For the Canadian natural gas industry, 1966 was a year of moderate expansion in all phases, with a strong demand continuing for sulfur and liquid hydrocarbons produced as by-products of gas processing. Value of natural gas production increased to $199 million and ranked sixth in terms of value of mineral ouput in Canada. Currently, natural gas provides over 70% of Canada's energy requirements. Proved remaining marketable reserves are estimated to be in excess of a 29-yr supply.

    Nasr, L.H.

    1978-05-01

    The study showed that the Geothermal Loan Guaranty Program has had only a negligible effect on geothermal development and the response to the program was far less than expected. The streamlining of environmental regulations and leasing policies, and the granting of intangible drilling cost write-offs and depletion allowances to operators would have had a greater impact on geothermal energy development. The loan guaranty program did not promote the undertaking of any new projects that would not have been undertaken without it. The program only accelerated the pace for some development which might have commenced in the future. Included in the study are recommendations for improving the operation of the program thereby increasing its attractiveness to potential applicants.

  13. World oil and gas exploration trends: A comparative study of national and U.S. private oil companies

    International Nuclear Information System (INIS)

    Ghouri, S.S.K.

    1991-01-01

    This study hypothesizes that private oil companies and state-owned, national oil companies (NOCs) have different objectives and priorities and thus that different behavioral models are needed to explain changes over time in the level of exploration by these two groups of companies. More specifically, exploration by private companies is expected to be more sensitive to changing oil prices than exploration by NOCs. The study develops three different sets of expected determinants of change over time in the level of exploration (for private companies, and two groups of NOCs-oil importers and non-OPEC oil exporters). In the private-sector model, exploration is driven by expected determinants of profitability, such as oil prices and exploration costs. The NOC models also include national-priority variables, such as import dependency. The study then tests these behavioral models by specifying and estimating econometric models for the period 1970-1988 for 11 companies from the three company groups. Three econometric models are used: static, Koyck distributed lag, and Almon polynomial distributed lag models. The study concludes on the basis of three comparisons that different behavioral models are needed to understand changes in the level of exploration by private companies and NOCs. First, the private-sector model is estimated for all companies. For private companies, the private-sector model works well, whereas for the NOCs it does not, presumably because important determinants of NOC exploration are excluded from the model. Second, when these excluded variables are included in the specification, regression results for the NOCs improve significantly. Third, the private companies have higher elasticities of exploration in both the short run and long run than the NOCs

    2006-01-01

    The implementation of structural adjustment programs (SAPs) in developing countries has been followed by a marked reduction in their progress on economic growth, health outcomes, and social indicators. Comprehensive and contextualized explorations of the effects of SAPs are needed to assist health and social policy-makers in better determining responses to such programs that continue to dominate global trade, aid and debt cancellation negotiations. A comparative case study of Argentina and Uruguay was developed exploring the effects of SAPs on health. Using a framework developed to analyze the relationship between globalization and health, changes in domestic policies resulting from SAPs and the corresponding economic, social and health outcomes of the countries were explored. In general, SAPs were implemented with greater severity and speed in Argentina than in Uruguay, with the greatest differences occurring over the 1980s. The more gradual and modest reforms implemented in Uruguay were associated with better economic, social and health outcomes. Findings support those of previous studies demonstrating that countries that have maintained more dynamic public social and health programming while applying SAPs have been better able to protect the health of the most vulnerable sectors of society.

    2001-04-01

    One of the great challenges for policy makers in the twenty first century is turning out to be global climate change caused by greenhouse gas emissions. Recent setbacks in international negotiations do not preclude the imposition of national emission targets. One option being studied to increase the economic efficiency of meeting these targets is the creation of emissions trading markets. The exploration of credit trading in the field of greenhouse gas emissions is carried out under the banner of the Greenhouse Gas Emission Reduction Trading (GERT) Pilot Project. One of its objectives is the development of the institutional framework required for the Clean Development Mechanism (CDM), Joint Implementation (JI), and other international credit trading programs. To ensure credits are awarded to projects in a fair and transparent manner, technical, methodological, and administrative processes must be put in place. The determination of project baselines and project boundaries represent two of the main challenges confronting policy makers in awarding the credits. A review of baseline and boundary methods was initiated by GERT, and this report also contains a description of the main advantages and drawbacks of the various methods being considered. Lessons learned and opportunities are especially important for GERT to provide proper guidance to developers. The context and rationale for baselines and boundary setting are first explored in this report, as well as the issues of importance, and common criteria for the evaluation of alternative methods. The principal options for baseline determination, advantages and disadvantages, and applicability in various contexts were reviewed in section 2. The topic of avoided electricity use, and how to set consistent baselines for it are discussed in section 3. Project boundary is the topic of section 4, including leakage, upstream and downstream emissions, rebound and positive spillover effects, and means by which these issues can de

    McWilliam, Nicky

    2010-01-01

    This paper reports an exploratory study of a school peer mediation program implemented as an alternative way to manage bullying and other destructive conflict. The study explores the effects of the program on the well-being of members of the school community by examining perceptions of students, staff and a sample of parents and former students. Drawing on therapeutic jurisprudence (TJ) the study explores whether the component parts of the program, separately or together, promote intended or unintended therapeutic effects. The preliminary findings of the study emphasise the importance of peer mediation training and suggest that existing scholarship in the area of school conflict resolution and peer mediation, when viewed through a TJ lens, may provide valuable insights into how to optimally configure programs for development and adoption in schools and other community settings. The study highlights the lack of attention paid by the legal system to valuable scholarship in the area of school conflict resolution and peer mediation, which may have implications for the understanding and development of legal processes and the law in general.

    2009-01-01

    A troubling trend noted in California has been an increase in the number of open positions for program directors of associate degree registered nursing (ADRN) programs. Positions remain open for extended periods of time, and the number of qualified applicants for such positions is insufficient. The loss of and ensuing slow replacement of ADRN program directors can put these programs in jeopardy of student admission suspension, or, worse yet, closure by the state nursing board. In this exploratory study, variables of social support and job satisfaction were studied. Variables were found to be limited opportunities for peer interaction, expressed discontent, and retention concerns. A significant positive relationship between job satisfaction and social support was noted. Recommendations for future research are offered.

    The steady state gas release, swelling and densification model previously developed for oxide fuels has been modified to accommodate the slow transients in temperature, temperature gradient, fission rate and pressure that are encountered in normal reactor operation. The gas release predictions made by the model were then compared to gas release data on LMFBR-EBRII fuels obtained by Dutt and Baker and reported by Meyer, Beyer, and Voglewede. Good agreement between the model and the data was found. A comparison between the model and three other sets of gas release data is also shown, again with good agreement

    To develop a framework for studying financial incentive program implementation mechanisms, the means by which physician practices and physicians translate incentive program goals into their specific office setting. Understanding how new financial incentives fit with the structure of physician practices and individual providers' work may shed some insight on the variable effects of physician incentives documented in numerous reviews and meta-analyses. Reviewing select articles on pay-for-performance evaluations to identify and characterize the presence of implementation mechanisms for designing, communicating, implementing, and maintaining financial incentive programs as well as recognizing participants' success and effects on patient care. Although uncommonly included in evaluations, evidence from 26 articles reveals financial incentive program sponsors and participants utilized a variety of strategies to facilitate communication about program goals and intentions, to provide feedback about participants' progress, and to assist-practices in providing recommended services. Despite diversity in programs' geographic locations, clinical targets, scope, and market context, sponsors and participants deployed common strategies. While these methods largely pertained to communication between program sponsors and participants and the provision of information about performance through reports and registries, they also included other activities such as efforts to engage patients and ways to change staff roles. This review covers a limited body of research to develop a conceptual framework for future research; it did not exhaustively search for new articles and cannot definitively link particular implementation mechanisms to outcomes. Our results underscore the effects implementation mechanisms may have on how practices incorporate new programs into existing systems of care which implicates both the potential rewards from small changes as well as the resources which may be

    Thornton, Steve; Giles, Wendy; Prescott, Debbie; Rhodes, David

    2011-06-01

    This paper reports on the efficacy of an accelerated teacher education program ( Growing Our Own) focused in remote Indigenous communities in the Northern Territory. The program is a joint initiative of Charles Darwin University and the Northern Territory Catholic Education Office, providing an intensive two-year program designed to educate Indigenous Teacher Assistants to full teacher status. We describe the growth in knowledge and confidence that has occurred through the program using the story of one of the students in the project, Philomena, as an evocative representation of the experiences of the participants in the program. This growth is particularly evident in one lesson that Philomena taught towards the end of the program in which she was able to challenge her previously accepted role as subservient to the non-Indigenous teacher. Our discussion highlights some key issues for improving outcomes for Indigenous children, including the potential mismatch between Western and Aboriginal ways of thinking in mathematics and developing the mathematical capacity of Indigenous teacher assistants in remote settings. We suggest that the mutual respect of the participants at various levels of Growing Our Own, the situated and purposeful nature of the learning, and the capacity of students to engage in that learning without abandoning their community responsibilities have been pivotal in enhancing educational outcomes in remote communities and in providing opportunities for Indigenous people.

    Fission gas release data are presented from 51 fuel rods irradiated as part of the LWBR irradiations test program. The fuel rods were Zircaloy-4 clad and contained ThO 2 or ThO 2 -UO 2 fuel pellets, with UO 2 compositions ranging from 2.0 to 24.7 weight percent and fuel densities ranging from 77.8 to 98.7 percent of theoretical. Rod diameters ranged from 0.25 to 0.71 inches and fuel active lengths ranged from 3 to 84 inches. Peak linear power outputs ranged from 2 to 22 kw/ft for peak fuel burnups up to 56,000 MWD/MTM. Measured fission gas release was quite low, ranging from 0.1 to 5.2 percent. Fission gas release was higher at higher temperature and burnup and was lower at higher initial fuel density. No sensitivity to UO 2 composition was evidenced

    2002-01-01

    A broad range of non-nuclear energy research and development activities are covered under the umbrella of the Program of Energy Research and Development (PERD) managed by Natural Resources Canada. The research and development budget amounts to 52.5 million dollars annually, and is distributed across twelve federal departments and agencies. Horizontal coordinated research activities are taking place. Of this total budget, approximately 14 million dollars annually are spent to carry out oil and gas research and development activities by five federal departments and one agency. A results-based management for PERD was recently implemented by the Office of Energy Research and Development in an effort to improve the strategic management. Some of the efforts are directed toward research in the following general classification: upstream activities, offshore and frontier activities, and cross-cutting activities. Upgrading technologies and advanced separation technologies with the focus on oil sands bitumen represent the main issues addressed under the heading upstream activities. The major issues studied in the offshore and frontier activities are: basin assessment and geotechnics, wind-wave-current modelling, managing sea ice, ice-structure interactions, transportation safety, marine operations and ship design, management of offshore drilling and production waste, oil spills remediation and environmental impact assessment of offshore wastes and produced waters. Flaring, pipelines and soil and groundwater remediation are topics classified under the heading cross-cutting activities. The authors provided an overview of the activities and identified the future trends in PERD to meet the requirements of the various stakeholders and the Canadian population. 1 tab

    2018-04-01

    Full Text Available Purpose: In order to achieve excellence, outsourced maintenance contractors in Oil&Gas sector play a key role due to the important impact of their task on security, availability and energy consumption. This paper presents the process followed in order to implement a Supplier Development Program in a refinery using Company Maturity Model (CoMM and the results obtained in three cases validating the method to obtain a strategic improvement project medium term grid. Design/methodology/approach: The methodology followed consists of constructing a CoMM capturing the knowledge existing in the refinery and applying it with three supplier improvement teams. Findings and conclusions have arised through an observation of the three processes and extracting common conclusions. Findings: The resulting CoMM has been used for self-assessment by three suppliers and has demonstrated its potential to define a medium-term improvement project road map validated by the customer. Furthermore, during the design and application processes, the contribution of CoMMs to the SECI process of knowledge management has been observed. Practical implications: The use of CoMMs in a service contractor context can be applied in other sectors. It contributes to alignment of targets between the supplier and customer companies and to knowledge sharing inside both firms. Originality/value: Maturity models in many transversal fields (CMMI, EFQM, BPMM, PEMM, etc. have been thoroughly studied in the literature. Less effort has been made analysing the case of using maturity models constructed and implemented by a company for its specific purposes. In this paper, the process followed by a company to establish a Supplier Development Process using CoMMs is described.

    2011-01-01

    Since the 1990s, the capital city of Thailand, Bangkok has been suffering from severe ambient particulate matter (PM) pollution mainly attributable to its wide use of diesel-fueled vehicles and motorcycles with poor emission performance. While the Thai government strives to reduce emissions from transportation through enforcing policy measures, the link between specific control policies and associated health impacts is inadequately studied. This link is especially important in exploring the co-benefits of greenhouse gas emissions reductions, which often brings reduction in other pollutants such as PM. This paper quantifies the health benefits potentially achieved by the new PM-related I/M programs targeting all diesel vehicles and motorcycles in the Bangkok Metropolitan Area (BMA). The benefits are estimated by using a framework that integrates policy scenario development, exposure assessment, exposure-response assessment and economic valuation. The results indicate that the total health damage due to the year 2000 PM emissions from vehicles in the BMA was equivalent to 2.4% of Thailand's GDP. Under the business-as-usual (BAU) scenario, total vehicular PM emissions in the BMA will increase considerably over time due to the rapid growth in vehicle population, even if the fleet average emission rates are projected to decrease over time as the result of participation of Thailand in post-Copenhagen climate change strategies. By 2015, the total health damage is estimated to increase by 2.5 times relative to the year 2000. However, control policies targeting PM emissions from automobiles, such as the PM-oriented I/M programs, could yield substantial health benefits relative to the BAU scenario, and serve as co-benefits of greenhouse gas control strategies. Despite uncertainty associated with the key assumptions used to estimate benefits, we find that with a high level confidence, the I/M programs will produce health benefits whose economic impacts considerably outweigh

    2016-01-01

    Selective concentration of ultra-trace components in air-like gases has an important application in analyzing volatile organic compounds in the gas. In the present study, we examined quench-condensation of the sample gas on a ZnO substrate below 50 K followed by temperature programmed desorption (TPD) (low temperature TPD) as a selective gas concentration technique. We studied two specific gases in the normal air; krypton as an inert gas and acetone as a reactive gas. We evaluated the relationship between the operating condition of low temperature TPD and the lowest detection limit. In the case of krypton, we observed the selective concentration by exposing at 6 K followed by thermal desorption at about 60 K. On the other hand, no selectivity appeared for acetone although trace acetone was successfully concentrated. This is likely due to the solvent effect by a major component in the air, which is suggested to be water. We suggest that pre-condensation to remove the water component may improve the selectivity in the trace acetone analysis by low temperature TPD.

    2010-01-01

    IntroductionNASA has played an influential role in bringing the enthusiasm of space science to schools across the United States since the 1980s. The evolution of this public outreach has led to a variety of NASA funded education programs designed to promote student interest in science, technology, engineering, math, and geography (STEM-G) careers.PurposeThis paper investigates the educational outreach initiatives, structure, and impact of two of NASA's largest educational programs: the NASA Explorer School (NES) and NASA Spaceward Bound programs.ResultsSince its induction in 2003 the NES program has networked and provided resources to over 300 schools across the United States. Future directions include further development of mentor schools for each new NES school selected, while also developing a longitudinal student tracking system for NES students to monitor their future involvement in STEM-G careers. The Spaceward Bound program, now in its third year of teacher outreach, is looking to further expand its teacher network and scientific collaboration efforts, while building on its teacher mentorship framework.

  4. Results from the DOE Advanced Gas Reactor Fuel Development and Qualification Program

    Energy Technology Data Exchange (ETDEWEB)

    2014-06-01

    Modular HTGR designs were developed to provide natural safety, which prevents core damage under all design basis accidents and presently envisioned severe accidents. The principle that guides their design concepts is to passively maintain core temperatures below fission product release thresholds under all accident scenarios. This level of fuel performance and fission product retention reduces the radioactive source term by many orders of magnitude and allows potential elimination of the need for evacuation and sheltering beyond a small exclusion area. This level, however, is predicated on exceptionally high fuel fabrication quality and performance under normal operation and accident conditions. Germany produced and demonstrated high quality fuel for their pebble bed HTGRs in the 1980s, but no U.S. manufactured fuel had exhibited equivalent performance prior to the Advanced Gas Reactor (AGR) Fuel Development and Qualification Program. The design goal of the modular HTGRs is to allow elimination of an exclusion zone and an emergency planning zone outside the plant boundary fence, typically interpreted as being about 400 meters from the reactor. To achieve this, the reactor design concepts require a level of fuel integrity that is better than that claimed for all prior US manufactured TRISO fuel, by a few orders of magnitude. The improved performance level is about a factor of three better than qualified for German TRISO fuel in the 1980’s. At the start of the AGR program, without a reactor design concept selected, the AGR fuel program selected to qualify fuel to an operating envelope that would bound both pebble bed and prismatic options. This resulted in needing a fuel form that could survive at peak fuel temperatures of 1250°C on a time-averaged basis and high burnups in the range of 150 to 200 GWd/MTHM (metric tons of heavy metal) or 16.4 to 21.8% fissions per initial metal atom (FIMA). Although Germany has demonstrated excellent performance of TRISO-coated UO

    2009-01-01

    Monitoring programs have the potential to identify population declines and differentiate among the possible cause(s) of these declines. Recent criticisms regarding the design of monitoring programs have highlighted a failure to clearly state objectives and to address detectability and spatial sampling issues. Here, we incorporate these criticisms to design an efficient monitoring program whose goals are to determine environmental factors which influence the current distribution and measure change in distributions over time for a suite of amphibians. In designing the study we (1) specified a priori factors that may relate to occupancy, extinction, and colonization probabilities and (2) used the data collected (incorporating detectability) to address our scientific questions and adjust our sampling protocols. Our results highlight the role of wetland hydroperiod and other local covariates in the probability of amphibian occupancy. There was a change in overall occupancy probabilities for most species over the first three years of monitoring. Most colonization and extinction estimates were constant over time (years) and space (among wetlands), with one notable exception: local extinction probabilities for Rana clamitans were lower for wetlands with longer hydroperiods. We used information from the target system to generate scenarios of population change and gauge the ability of the current sampling to meet monitoring goals. Our results highlight the limitations of the current sampling design, emphasizing the need for long-term efforts, with periodic re-evaluation of the program in a framework that can inform management decisions.

    Animal models have been critical in building evidence that the prenatal experience and intrauterine environment are capable of exerting profound and permanent effects on metabolic health through developmental programming of obesity. However, despite physiological and evolutionary similarities, nonhuman primate models are relatively rare. The common marmoset monkey ( Callithrix jacchus) is a New World monkey that has been used as a biomedical model for well more than 50 years and has recently been framed as an appropriate model for exploring early-life impacts on later health and disease. The spontaneous, multifactorial, and early-life development of obesity in the common marmoset make it a valuable research model for advancing our knowledge about the role of the prenatal and placental mechanisms involved in developmental programming of obesity. This paper provides a brief overview of obesity in the common marmoset, followed by a discussion of marmoset reproduction and placental characteristics. We then discuss the occurrence and utility of variable intrauterine environments in developmental programming in marmosets. Evidence of developmental programming of obesity will be given, and finally, we put forward future directions and innovations for including the placenta in developmental programming of obesity in the common marmoset.

  1. Memories of GAMES: Exploring the Long-Term Impacts of After-School Museum Programming on Girls' Attitudes Towards Science

    Science.gov (United States)

    Snow, Sarah Elizabeth

    The purpose of this study is to investigate any lasting impacts of the University of Colorado Museum of Natural History's Girls at the Museum Exploring Science (GAMES) Program. Using assessment document analysis, student focus groups, and adult interviews, this study examined whether students' positive associations with science continue after completion of the program and whether the program affects the academic and career choices of past participants. Results from the analysis suggest that GAMES has a generally positive impact on participant attitudes towards science in both the short- and long-term. These results also support existing research in identifying key factors in the success of the program including hands-on activities, exposure to diverse careers and female role models, and the incorporation of authentic objects and experiences. These factors of success can contribute to the evidence base about the role of informal education programs in increasing science participation among women, as well as ways in which schools and universities can collaborate to effectively serve populations that are traditionally underrepresented in the sciences.

    Full Text Available Objective. Mental health service users experience high rates of cardiometabolic disorders and have a 20–25% shorter life expectancy than the general population from such disorders. Clinician-led health behavior programs have shown moderate improvements, for mental health service users, in managing aspects of cardiometabolic disorders. This study sought to potentially enhance health initiatives by exploring (1 facilitators that help mental health service users engage in better health behaviors and (2 the types of health programs mental health service users want to develop. Methods. A qualitative study utilizing focus groups was conducted with 37 mental health service users attending a psychosocial rehabilitation center, in Northern British Columbia, Canada. Results. Four major facilitator themes were identified: (1 factors of empowerment, self-value, and personal growth; (2 the need for social support; (3 pragmatic aspects of motivation and planning; and (4 access. Participants believed that engaging with programs of physical activity, nutrition, creativity, and illness support would motivate them to live more healthily. Conclusions and Implications for Practice. Being able to contribute to health behavior programs, feeling valued and able to experience personal growth are vital factors to engage mental health service users in health programs. Clinicians and health care policy makers need to account for these considerations to improve success of health improvement initiatives for this population.

    2014-02-01

    This study explored the yearlong learning processes of two first-year secondary science teachers participating in an online mentoring program, through examination of their written dialogues within the program and other data. Using a case study method, this study (a) explored the patterns of written dialogues between the two new teachers and their mentors over the course of a year, (b) documented pertinent topics of importance, and finally (c) illustrated the new realities created in the mentees' classrooms as a result of the online mentoring process. Penelope and Bradley, who taught at an urban school and at a suburban school respectively, were selected as subjects. Our analysis revealed that the two pairs of mentee-mentors showed different participation patterns that affected the intensity of the creation of new realities, and affected whether the mentees tried/vetted new teaching practices suggested by their mentors. Yet, analysis also revealed that certain elements in the written dialogues between pairs were found to be similar, in that construction of knowledge was evident between both pairs when friction developed and appropriate teamwork emerged to deal with it. The topics of greatest interest and importance within the dialogues were those related to the logistics of the school system and the processes and methodologies of teaching. These results suggest that online mentoring programs are an effective dialogical tool for transferring the knowledge of experts to novices, and for thus expediting the professional induction and growth of new science teachers.

    Given the significant potential of continuous quality improvement (CQI) programs in enhancing overall levels of patient safety, community pharmacies in North America are under increasing pressure to have a formal and documented CQI program in place. However, while such initiatives may seem great on paper, in practice the outcomes of such programs to community pharmacy practice remain unclear. To explore the perceived outcomes identified by community pharmacies that adopted and actively used a standardized (i.e., common across pharmacies) CQI program for at least 1 year and to develop a framework for how such outcomes were achieved. A multi-site study of SafetyNET-Rx, a standardized and technologically sophisticated (e.g., online reporting of medication errors to a national database) CQI program, involving community pharmacies in Nova Scotia, Canada, was performed. During the summer and fall of 2011, 22 interviews were conducted with the CQI facilitators in 12 Nova Scotia community pharmacies; equally split between independent/banners and corporate chains. Of the CQI facilitators, 14 were pharmacists, while the remaining eight were pharmacy technicians. Thematic analysis following the procedures presented by Braun and Clarke was adopted to identify and explore the major outcomes. Results of the thematic analysis highlighted a number of perceived outcomes from the use of a standardized CQI program in community pharmacies, specifically: (1) perceived reduction in the number of medication errors that were occurring in the pharmacy, (2) increased awareness/confidence of individual actions related to dispensing, (3) increased understanding of the dispensing and related processes/workflow, (4) increased openness to talking about medication errors among pharmacy staff, and (5) quality and safety becoming more entrenched in the workflow (e.g., staff is more aware of their roles and responsibilities in patient safety and confident that the dispensing processes are safe and

This quantification, based on both a detailed engineering study and on measurements, indicates Dutch methane emissions to be about 30 to 50 k tonne higher than previously expected. The main reason for this difference is, that in this quantification emissions during exploitation and fugitive and incidental emissions are incorporated, whereas they have been neglected earlier. 3 tabs., 11 refs

  11. A New Radio Spectral Line Survey of Planetary Nebulae: Exploring Radiatively Driven Heating and Chemistry of Molecular Gas

    Science.gov (United States)

    Bublitz, Jesse

    Planetary nebulae contain shells of cold gas and dust whose heating and chemistry is likely driven by UV and X-ray emission from their central stars and from wind-collision-generated shocks. We present the results of a survey of molecular line emissions in the 88 - 235 GHz range from nine nearby (Radioastronomie Millimetrique. Rotational transitions of nine molecules, including the well-studied CO isotopologues and chemically important trace species, were observed and the results compared with and augmented by previous studies of molecular gas in PNe. Lines of the molecules HCO+, HNC, HCN, and CN, which were detected in most objects, represent new detections for five planetary nebulae in our study. Flux ratios were analyzed to identify correlations between the central star and/or nebular ultraviolet/X-ray luminosities and the molecular chemistries of the nebulae. Analysis reveals the apparent dependence of the HNC/HCN line ratio on PN central star UV luminosity. There exists no such clear correlation between PN X-rays and various diagnostics of PN molecular chemistry. The correlation between HNC/HCN ratio and central star UV luminosity hints at the potential of molecular emission line studies of PNe for improving our understanding of the role that high-energy radiation plays in the heating and chemistry of photodissociation regions.

    The relationship that exists between coalification and the formation of liquid petroleum and natural gas depends entirely upon the temperature in the earth's crust and the duration of heating. The degree of coalification can be determined by reflectivity measurements on very small vitrinitic (huminitic) inclusions in sedimentary rocks, because a satisfactory correlation has been established between mean reflectivity (R/sub m Oil/) and different parameters of chemical rank using 900 vitrites of different rank. This paper reports the considerable experience obtained with this method using cores and cuttings from boreholes of the German oil industry. Subsequently, examples from other countries are described which confirm the applicability of the method. Results obtained so far suggest that oil deposits may occur when the reflectivity (R/sub m Oil/) of the vitrinite lies between 0.3 and 1.0% (brown coal to high-volatile bituminous stage), whereas economic gas deposits may be found when R/sub m Oil/ extends from 0.7 to 2.0% (high-low volatile bituminous stage).

  13. Monitoring of good practices programs and independence for electricity and natural gas system operators. Summary report 2011

    2012-07-01

    Electricity and natural gas transmission system operators (TSO) and distribution system operators (DSO) are regulated operators that provide public service functions for the benefit of the network users and the consumers they serve. Accordingly, European and French law requires that they be under independent and nondiscriminatory obligations. In particular, they must develop a good practices program which includes a range of measures to prevent the risk of discriminatory practices in network access. Pursuant to Article L.134-15 of the Energy Code, the Energy Regulatory Commission (CRE) is publishing this year its 7. annual report on the monitoring of good practices programs and independence for electricity and natural gas system operators for the year 2011. This report is based on analysis of the 'reports on the implementation of good practices programs' submitted to the CRE by the operators in late 2011 and audits carried out by the CRE services in these companies in 2011. These elements were supplemented and clarified by many exchanges with the operators, in particular during the committee hearings that took place in spring 2012 with each network operator. This report is structured around four cross-cutting themes, supplemented by individual analyses of each operator's situation. The cross-cutting issues address communication and user's awareness of the network operators, the new compliance officer function, TSO certification and, finally, the results of the 'mystery shopper' telephone survey carried out by the CRE. The individual situations analysed were those of the eight DSOs serving over 100,000 customers (ERDF, ES, URM, SRD and Geredis-Deux-Sevres for electricity, GrDF, Regaz-Bordeaux and Reseau GDS for natural gas) and the three TSOs (RTE for electricity and GRTgaz and TIGF for natural gas)

  14. Evaluating the potential economic effectiveness of scientific research in the area of geological exploration for oil and gas

    The category of ''potential effect'' is inherent to scientific developments in oil geology. This effect is associated with a quantity of labor in the sphere of scientific research which is embodied in the extracted information and stored until its complete use in production. The potential effect can be predicted. It is an indicator of economic effectiveness of scientific research. Distribution of the coefficient of creativity (innovation) for scientific research for geological exploration is suggested. The system of calculating the economic effect contains real stimuli for increasing economic efficiency. The most important of them are: establishment of the most promising trends for geological exploration which guarantee maximum increase in hydrocarbon reserves; decrease in net cost which will guarantee the obtaining of great profit; conducting of research on a higher level, in a large quantity of stages of work. This results in an increase in the percentage of participation of science in the production process, and this means, an increase in its economic effectiveness.

    Experiment and investigation are conducted in the Yurihara District, Akita Prefecture, to verify that the magnetotelluric (MT) method can be effectively applied to oil and gas fields. In the Yurihara district there exist a number of pits dug for exploration or production, and records on seismic surveys conducted, and therefore the geological structure of this district can be explained fairly well. The oil and gas reservoirs belong in the Nishikurosawa stratum overlain by the Onagawa stratum and Funakawa stratum. The Nishikurosawa rocks, basaltic rocks for example, present a resistivity of approximately 5 ohm/m which is higher than that of the other two that is more or less 1 ohm/m. Under the circumstances, experiment and investigation are conducted so as to detect the Nishikurosawa basaltic rocks as a high-resistivity stratum located under low-resistivity strata by use of the MT method. As the result, a high-resistivity stratum corresponding to the Nishikurosawa basaltic stratum is detected under low-resistivity strata, and the three-dimensional structure of the basaltic stratum is disclosed. In this stratum, the resistivity value gradually increases from south toward north with occasional abrupt rises, and it is found that such abrupt rises result from oil and gas producing strata where exploitation is under way. 5 refs., 6 figs.

    The Lower Paleozoic basins of eastern Poland have recently been the focus of intensive exploration for shale gas. In the Lublin Basin potential unconventional play is related to Lower Silurian source rocks. In order to assess petroleum charge history of these shale gas reservoirs, 1-D maturity modeling has been performed. In the Łopiennik IG-1 well, which is the only well that penetrated Lower Paleozoic strata in the study area, the uniform vitrinite reflectance values within the Paleozoic section are interpreted as being mainly the result of higher heat flow in the Late Carboniferous to Early Permian times and 3500 m thick overburden eroded due to the Variscan inversion. Moreover, our model has been supported by zircon helium and apatite fission track dating. The Lower Paleozoic strata in the study area reached maximum temperature in the Late Carboniferous time. Accomplished tectono-thermal model allowed establishing that petroleum generation in the Lower Silurian source rocks developed mainly in the Devonian - Carboniferous period. Whereas, during Mesozoic burial, hydrocarbon generation processes did not develop again. This has negative influence on potential durability of shale gas reservoirs.

  17. Use of nuclear explosions to create gas condensate storage in the USSR. LLL Treaty Verification Program

    The Soviet Union has described industrial use of nuclear explosions to produce underground hydrocarbon storage. To examples are in the giant Orenburg gas condensate field. There is good reason to believe that three additional cavities were created in bedded salt in the yet to be fully developed giant Astrakhan gas condensate field in the region of the lower Volga. Although contrary to usual western practice, the cavities are believed to be used to store H 2 S-rich, unstable gas condensate prior to processing in the main gas plants located tens of kilometers from the producing fields. Detonations at Orenburg and Astrakhan preceded plant construction. The use of nuclear explosions at several sites to create underground storage of highly corrosive liquid hydrocarbons suggests that the Soviets consider this time and cost effective. The possible benefits from such a plan include degasification and stabilization of the condensate before final processing, providing storage of condensate during periods of abnormally high natural gas production or during periods when condensate but not gas processing facilities are undergoing maintenance. Judging from information provided by Soviet specialists, the individual cavities have a maximum capacity on the order of 50,000 m 3

    The objective of this study is to analyze the generation and disposal of solid waste from the exploration and production activities of oil and natural gas in Brazilian waters. We used data from the implementation reports of pollution control project of the activities licensed by IBAMA. During 2009 the activities related to exploration and production of offshore oil and gas produced a total of 44,437 tons of solid waste, with the main waste generated corresponding to: oily waste (16,002 t); Metal uncontaminated (11,085 t); contaminated waste (5630 t), non recycling waste (4935 t); Wood uncontaminated (1,861 t), chemicals (1,146 t). Considering the total waste generated by activities during the period analyzed, it was observed that 54.3% are made up of waste Class I (hazardous waste), 27.9% of Class II wastes (waste non-hazardous non-inert); and 17.8% of waste Class IIB (non-hazardous and inert waste). The results obtained in this work enabled the scenario of waste generation by the E and P offshore activities. As a result, the survey serves as a starting point for monitoring the progress in implementing the projects sought Pollution Control of licensed projects, as well as support the monitoring of reflexes arising from the intensification of activities in certain regions.

    2015-03-27

    Nevada Geothermal Power Company (NGP) was awarded DOE Award DE-EE0002834 in January 2010 to conduct sub-soil gas and fluid inclusion studies and slim well drilling at its Black Warrior Project (now known as North Valley) in Washoe and Churchill Counties, Nevada. The project was designed to apply highly detailed, precise, low-cost subsoil and down-hole gas geochemistry methods from the oil and gas industry to identify upflow zone drilling targets in an undeveloped geothermal prospect. NGP ran into multiple institutional barriers with the Black Warrior project relating to property access and extensive cultural survey requirement. NGP requested that the award be transferred to NGP’s Pumpernickel Valley project, due to the timing delay in obtaining permits, along with additional over-budget costs required. Project planning and permit applications were developed for both the original Black Warrior location and at Pumpernickel. This included obtaining proposals from contractors able to conduct required environmental and cultural surveying, designing the two-meter probe survey methodology and locations, and submitting Notices of Intent and liaising with the Bureau of Land Management to have the two-meter probe work approved. The award had an expiry date of April 30, 2013; however, due to the initial project delays at Black Warrior, and the move of the project from Black Warrior to Pumpernickel, NGP requested that the award deadline be extended. DOE was amenable to this, and worked with NGP to extend the deadline. However, following the loss of the Blue Mountain geothermal power plant in Nevada, NGP’s board of directors changed the company’s mandate to one of cash preservation. NGP was unable to move forward with field work on the Pumpernickel property, or any of its other properties, until additional funding was secured. NGP worked to bring in a project partner to form a joint venture on the property, or to buy the property. This was unsuccessful, and NGP notified

    Full Text Available This study investigates the influence of employee fitness programs on organizational sustainability performance from the perspective of organizational support as perceived by employees. Organizational sustainability performance was specified as a second-order factor, which was affected by three first-order factors: financial performance, social performance, and environmental performance. A snowball sampling method was employed to conduct an online survey of working adults in Shanghai to test the proposed hypotheses. Results show that perceived organizational support toward employee fitness has a positive and significant effect on organizational sustainability performance, and the positive effect is mediated by job satisfaction and organizational commitment. This study also provides theoretical and managerial implications.
