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

RISK REDUCTION WITH A FUZZY EXPERT EXPLORATION TOOL

Energy Technology Data Exchange (ETDEWEB)

Incomplete or sparse data such as geologic or formation characteristics introduce a high level of risk for oil exploration and development projects. ''Expert'' systems developed and used in several disciplines and industries have demonstrated beneficial results when working with sparse data. State-of-the-art expert exploration tools, relying on a database, and computer maps generated by neural networks and user inputs, have been developed through the use of ''fuzzy'' logic, a mathematical treatment of imprecise or non-explicit parameters and values. Oil prospecting risk has been reduced with the use of these properly verified and validated ''Fuzzy Expert Exploration (FEE) Tools.'' Through the course of this project, FEE Tools and supporting software were developed for two producing formations in southeast New Mexico. Tools of this type can be beneficial in many regions of the U.S. by enabling risk reduction in oil and gas prospecting as well as decreased prospecting and development costs. In today's oil industry environment, many smaller exploration companies lack the resources of a pool of expert exploration personnel. Downsizing, volatile oil prices, and scarcity of domestic exploration funds have also affected larger companies, and will, with time, affect the end users of oil industry products in the U.S. as reserves are depleted. The FEE Tools benefit a diverse group in the U.S., allowing a more efficient use of scarce funds, and potentially reducing dependence on foreign oil and providing lower product prices for consumers.

Crude operators: the future of the oil industry

International Nuclear Information System (INIS)

Rowell, Andrew.

1997-01-01

Technological advances and the maturity of existing oil fields have spurred oil companies to explore for oil and extract it from previously inaccessible or ''frontier'' areas, both offshore and onshore. In many cases, such prospecting and production will have severe environmental impacts and serious social, ethical and cultural consequences. The challenge is not just to halt such exploration and extraction, but to halt oil consumption itself. (author)

Forecasting of reservoir pressures of oil and gas bearing complexes in northern part of West Siberia for safety oil and gas deposits exploration and development

Science.gov (United States)

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.

A Contemporary Introduction to Essential Oils: Chemistry, Bioactivity and Prospects for Australian Agriculture

Directory of Open Access Journals (Sweden)

Nicholas Sadgrove

2015-03-01

Full Text Available This review is a comprehensive introduction to pertinent aspects of the extraction methodology, chemistry, analysis and pharmacology of essential oils, whilst providing a background of general organic chemistry concepts to readers from non-chemistry oriented backgrounds. Furthermore, it describes the historical aspects of essential oil research whilst exploring contentious issues of terminology. This follows with an examination of essential oil producing plants in the Australian context with particular attention to Aboriginal custom use, historical successes and contemporary commercial prospects. Due to the harsh dry environment of the Australian landmass, particularly to the cyclical climatic variation attendant upon repeated glaciation/post-glaciation cycles, the arid regions have evolved a rich assortment of unique endemic essential oil yielding plants. Though some of these aromatic plants (particularly myrtaceous species have given birth to commercially valuable industries, much remains to be discovered. Given the market potential, it is likely that recent discoveries in our laboratory and elsewhere will lead to new product development. This review concludes with an emphasis on the use of chemotaxonomy in selection of commercially viable cultivar chemotypes from the Australian continent. Finally, drawing largely from our own results we propose a list of Australian endemic species with novel commercial potential.

The detailed descriptive information in this book is based on 389 US patents that deal with geophysical and geochemical techniques useful for the exploration of hydrocarbons and minerals. Where it was necessary to round out the complete technological picture, a few paragraphs from cited government reports have been included. These techniques are used in prospecting for oil, coal, oil shale, tar sand and minerals. The patents are grouped under the following chapters: geochemical prospecting; geobiological prospecting; geophysical exploration; magnetic geophysical prospecting; gravitational geophysical prospecting; electrical geophysical prospecting; nuclear geophysical prospecting; seismic geophysical prospecting; and exploratory well drilling. This book serves a double purpose in that it supplies detailed technical information and can be used as a guide to the US patent literature in this field. By indicating all the information that is significant, and eliminating legal jargon and juristic phraseology, this book presents an advanced, industrially oriented review of modern methods of geophysical and geochemical exploration techniques

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

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

Energy Technology Data Exchange (ETDEWEB)

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.

Information asymmetries, information externalities, oil companies strategies and oil exploration information efficiency

International Nuclear Information System (INIS)

Nyouki, E.

1998-07-01

Both for economics (in general) and energy economics matters, it is important to reach oil exploration efficiency. To achieve this aim, a pragmatic approach is to use the concept of information efficiency which means that the different tracts have to be drilled in the decreasing order of estimated profitabilities, estimations being made on the basis of the best (in the sense of reliability) available information. What does 'best available information' mean? It corresponds either to the information held by the most experienced oil companies (due to the existence of information asymmetries to the profit of these companies), or to information revealed by the drilling and which allows to revise probabilities of success on neighboring tracts with similar geological features (due to the existence of information externalities). In consideration of these information asymmetries and externalities, we will say that exploration is information efficient when. -- on the one hand, initial exploration choices are directed by the most experienced companies, - and, on the other hand, during the drilling phase, in the face of the information externality, companies adopt a sequential drilling, i.e. excluding both over-investment and strategic under-investment. The topic we deal with in this thesis is then to know if oil companies, when they are put in normal competition conditions, are likely to make emerge a state of information efficiency in exploration, the analysis being conducted theoretically and empirically.

Possible uses of geochemical and isotopical investigations of ground waters in oil and gas prospecting

International Nuclear Information System (INIS)

Mercado, A.; Kahanovitz, Y.

1978-07-01

This work describes the use of geochemical investigation of ground waters for finding deep organic accumulations. It is based on the identification of abnormal values of chemical and isotopical parameters: bicarbonates, CO 2 , sulfates, carbon 13 and carbon 14. Further improvements will make this method a useful tool in oil and gas prospecting and detection as well as in the detection of geochemical anomalies. The advantages of the method are its low cost and relative rapidity; the disadvantage is that it can be carried out only when water sources are present in the exploration field. (B.G.)

The global thirst for vegetable oil can be regarded as one of the greatest environmental challenges of the 21st Century and interest has intensified with the prospect of biofuels. Palm oil has risen to become the dominant player on the vegetable oil market – and the main recipient of environmental...... scrutiny. Focusing specifically on the Malaysian context, this paper analyses the major environmental, social and economic impacts associated with palm oil production. Drawing on recently published research, publicly available data and a comparison made with a recent sustainability initiative undertaken...... by the hydropower industry – an equally controversial and highly scrutinised sector – it is argued that the full extent of the impacts of palm oil should be acknowledged by those on both sides of the debate. Moreover, it is argued that by moving towards a less polarised version of the palm oil narrative and one...

VSAT: opening new horizons to oil and gas explorations

Science.gov (United States)

Al-Dhamen, Muhammad I.

2002-08-01

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

Geologically speaking, Colombia is a very attractive country for the world oil community. According to this philosophy new and important steps are being taken to reinforce the oil sector: Expansion of the exploratory frontier by including a larger number of sedimentary areas, and the adoption of innovative contracting instruments. Colombia has to offer, Greater economic incentives for the exploration of new areas to expand the exploratory frontier, stimulation of exploration in areas with prospectivity for small fields. Companies may offer Ecopetrol a participation in production over and above royalties, without it's participating in the investments and costs of these fields, more favorable conditions for natural gas seeking projects, in comparison with those governing the terms for oil

Prospects for the exploitation of Jordan oil shale

International Nuclear Information System (INIS)

Jaber, J.O; Probert, S.D.; Badr, O.

1997-01-01

Oil shale is the major indigenous fossil-fuel in Jordan: its predicted reserves, of about 5·10 1 0 tonnes, should be sufficient to satisfy Jordan's energy requirements for several centuries. Jordanian oil shale has, on an average, a gross calorific value of between 5 and 7 MJ/kg, an oil yield of ∼ 10 %, and a sulfur content of approximately 3 % by weight of the raw shale (i.e. 7 to 9 % of the organic matter content). Using the oil shale as the input fuel, a multipurpose production process (i.e. retorting, electricity generation, thermal water-desalination, chemicals production as well as mineral extraction) could achieve high utilisation-factors of both its chemical and energy potentials. In the long-term, oil shale is the only indigenous energy resource that could reduce Jordan's dependence on imported crude oil and hence ease the pressure on the national economy. The conversion of oil shale into a liquid or gaseous fuel and raw materials will be of decisive importance in attempts to secure the future of energy supplies. So national efforts devoted to the exploration for, and harnessing more economically, this energy resource, while limiting the associated adverse environmental impacts, should be accelerated.

This paper reports the conditions of national affairs, oil industry, and prospecting, development, production of oil and natural gas in Ivory Coast in western Africa. All of oil and natural gas are produced in Cretaceous and Tertiary sedimentary basins on the continental margin off the coast of Ivory Coast and Ghana. In 1970 the first oil field (Belier) was discovered by the test boring drilled under the sea, and in 1980 Espoir Oil Field was discovered. No further new oil field, however, has been discovered since then. The total production until 1987, amounts to 45.55 million bbl and the minable reserve is estimated about 84 million bbl. The production reached the maximum 1984, and thereafter has gone down. Few plans of prospecting are carried out recently. (10 figs, 2 tabs)

Value of the principles of ''isolation of basins and their boundaries'' and ''isolation of basins and elevations'' in prospecting for oil and gas in the oil and gas basin of China

Energy Technology Data Exchange (ETDEWEB)

Chzhan, V.; Li, Yu.; Se, M.

1982-01-01

A feature of the Chinese oil and gas basins is their fracturing into a large number (to several dozen in one oil and gas basin) isolated basins which are controlled by fault disorders. In these basins in which thick masses of Mesozoic and mainly Cenozoic sedimentary rocks are developed, the main volumes of source rocks are concentrated. Migration of hydrocarbons usually occurs to short distances not exceeding tens of kilometers. From the experience of prospecting and exploration back in the 1950's it was established that thick masses in the central zones of the basins are favorable for processes of hydrocarbon generation, while accumulation occurs in the elevated peripheral parts of the basins and in the regions of the central elevations. The zones of articulation of the central elevations and the edges of the basins are very promising for prospecting for local structures. Examples of large fields which are subordinate to these laws are the largest oil fields in China, Lyakhoe, Dagan and Shenli which are located along the edges of the Bokhayvan basin in the North Chinese oil and gas basin and the Datsin field which is confined to the central elevation of the Sunlyao basin.

The aim of the study is to deepen understanding the role of palm oil on Indonesian economy, poverty elevation and to investigate the positive and negative impacts of oil palm expansion, due to the burden of GHG emissions; and prospect to be more sustainable palm oil industry. The statistics show that average rural poverty tends to be lower and Gross Regional Product tends to be higher in provinces which have greater levels of oil palm cultivation. Indonesian oil palm will grow from 10.6 in 2013 to 13.7 million ha by 2020. This will release 135.59 million tons of CO2 if nothing is done to mitigate BAU emissions. Unless there are sustained efforts to redirect development and expansion of oil palm, plantation growth will continue to encroach on intact forest and peat land.. In fact Indonesia has large areas of degraded land, an estimated total 19,144,000 ha is available for planting oil palm and other crops. A large-scale expansion program driven by estate companies needs to be accompanied by effective smallholder development program in order to achieve the best outcome for local farmers and avoid the conflicts.

Harrington, P.

1998-01-01

The decline in oil and gas exploration activity in Western Canada is discussed. In the third quarter of 1998, a total of 397 exploratory tests were reported compared to 768 during the same period in 1997. Low world oil prices are blamed as the cause of this decline. The declining exploration activity in 1998 was led by Alberta, with 289 new pool wildcat (NPW) announcements along with 25 new field wildcat (NFW) locations. Saskatchewan was in second place with 67 exploratory announcements, but compared to 329 in 1997, this represents an 80 per cent drop. British Columbia had a total of 15 exploratory wells resulting in three oil discoveries and 11 gas completions. Geological features, well characteristics and early production figures from several of the new wells in the Killam fields in southwest Saskatchewan were received special attention. 1 tab., 3 figs

The Oil Security Metrics Model: A Tool for Evaluating the Prospective Oil Security Benefits of DOE's Energy Efficiency and Renewable Energy R&D Programs

Energy Technology Data Exchange (ETDEWEB)

Greene, David L [ORNL; Leiby, Paul Newsome [ORNL

2006-05-01

Energy technology R&D is a cornerstone of U.S. energy policy. Understanding the potential for energy technology R&D to solve the nation's energy problems is critical to formulating a successful R&D program. In light of this, the U.S. Congress requested the National Research Council (NRC) to undertake both retrospective and prospective assessments of the Department of Energy's (DOE's) Energy Efficiency and Fossil Energy Research programs (NRC, 2001; NRC, 2005). ("The Congress continued to express its interest in R&D benefits assessment by providing funds for the NRC to build on the retrospective methodology to develop a methodology for assessing prospective benefits." NRC, 2005, p. ES-2) In 2004, the NRC Committee on Prospective Benefits of DOE's Energy Efficiency and Fossil Energy R&D Programs published a report recommending a new framework and principles for prospective benefits assessment. The Committee explicitly deferred the issue of estimating security benefits to future work. Recognizing the need for a rigorous framework for assessing the energy security benefits of its R&D programs, the DOE's Office of Energy Efficiency and Renewable Energy (EERE) developed a framework and approach for defining energy security metrics for R&D programs to use in gauging the energy security benefits of their programs (Lee, 2005). This report describes methods for estimating the prospective oil security benefits of EERE's R&D programs that are consistent with the methodologies of the NRC (2005) Committee and that build on Lee's (2005) framework. Its objective is to define and implement a method that makes use of the NRC's typology of prospective benefits and methodological framework, satisfies the NRC's criteria for prospective benefits evaluation, and permits measurement of that portion of the prospective energy security benefits of EERE's R&D portfolio related to oil. While the Oil Security Metrics (OSM) methodology described

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.

Exploration and development of offshore oil and gas fields. [North Sea

Energy Technology Data Exchange (ETDEWEB)

1979-01-01

In the last 9 years, the British companies, based on their rich engineering and commercial experience, have directed a considerable part of their material and manpower resources at developing oil and gas fields in the North Sea. The technological innovations used by British industry are: aero- and marine surveys to prospect for oil, underwater laying of pipelines, arrangement of platforms, etc.; exploratory drilling in the open sea and on dry land; design of platforms with regard for the depth of the water and unique weather conditions of the North Sea, their assembly and development; use of auxiliary ships and helicopters, and diving equipment.

Oil prospection using the tectonic plate model

Science.gov (United States)

Pointu, Agnès

2015-04-01

Tectonic plate models are an intellectual setting to understand why oil deposits are so uncommon and unequally distributed and how models can be used in actual oil and gas prospection. In this case, we use the example of the Ghawar deposit (Saudi Arabia), one of the largest producing well in the world. In the first step, physical properties of rocks composing the oil accumulation are studied by laboratory experiments. Students estimate the porosity of limestone and clay by comparing their mass before and after water impregnation. Results are compared to microscopic observations. Thus, students come to the conclusion that oil accumulations are characterized by superposition of rocks with very different properties: a rich organic source rock (clays of the Hanifa formation), a porous reservoir rock to store the petroleum in (limestones of the Arab formation) and above an impermeable rock with very low porosity (evaporites of the Tithonien). In previous lessons, students have seen that organic matter is usually mineralized by bacteria and that this preservation requires particular conditions. The aim is to explain why biomass production has been so important during the deposit of the clays of the Hanifa formation. Tectonic plate models make it possible to estimate the location of the Arabian Peninsula during Jurassic times (age of Hanifa formation). In order to understand why the paleo-location of the Arabian Peninsula is important to preserve organic matter, students have different documents showing: - That primary production of biomass by phytoplankton is favored by climatic conditions, - That the position of continents determinate the ocean currents and the positions of upwelling zones and zones where organic matter will be able to be preserved, - That north of the peninsula there was a passive margin during Jurassic times. An actual seismic line is studied in order to highlight that this extensive area allowed thick sedimentary deposits to accumulate and that fast

Exploring asymmetric behavior pattern from Indian oil products prices using NARDL and GHSOM approaches

2015-01-01

The present work endeavors to explore the potential asymmetries in the pricing of oil products in India where prices are not only affected by the crude oil price changes in the international markets but are also subject to government interventions. In order to protect domestic consumers from this volatility, historically the government of India tried to control the domestic price of petroleum products by cross subsidization and giving subsidies. In this paper, we analyze the impact of crude oil price on domestic oil prices by applying nonlinear autoregressive distributed lag (NARDL) and Growing Hierarchical Self-Organizing Map (GHSOM) approaches for the period of April, 2005–July, 2014. The GHSOM has been explored through pattern analysis on the asymmetric behavior using similarity measures. From the study it can be interpreted that the prices of products left to be determined by the market exhibit a strong asymmetry. However, pricing of the products that are monitored and controlled by the government do not exhibit any such asymmetry. Hence, the question still remains – should the government intervene in pricing petroleum products when monopolistic attitudes of large oil companies are detrimental to the interest of retail consumers? - Highlights: • We explored the potential asymmetries in the pricing of oil products in India. • Analyze cointegration and asymmetric behavior of oil products by NARDL approach. • GHSOM method has been explored for pattern analysis on the asymmetric behavior. • The analysis reveals that the market determined prices exhibits a strong asymmetry. • Oil product pricing controlled by the government do not exhibit such asymmetry.

Statistics of Petroleum Exploration in the World Outside the United States and Canada Through 2001

Attanasi, E.D.; Freeman, P.A.; Glovier, Jennifer A.

2007-01-01

Future oil and gas supplies depend, in part, on the reserves that are expected to be added through exploration and new discoveries. This Circular presents a summary of the statistics and an analysis of petroleum exploration in the world outside the United States and Canada (the study area) through 2001. It updates U.S. Geological Survey Circular 1096 (by E.D. Attanasi and D.H. Root, 1993) and expands coverage of the statistics to areas where drilling and discovery data have recently become available. These new areas include China, the formerly Communist countries of Eastern Europe, and the countries that once were part of the former Soviet Union in Europe and Asia. Data are presented by country but are organized by petroleum provinces delineated by the U.S. Geological Survey World Energy Assessment Team (USGS Digital Data Series DDS?60, published in 2000). The data and analysis are presented in maps and graphs, providing a visual summary of the exploration maturity of an area. The maps show the delineated prospective areas and explored areas through 2001; explored areas have a drilling density that would rule out the occurrence of undetected large petroleum accumulations. Graphs summarize the exploration yields in terms of cumulative recoverable discovered oil and gas by delineated prospective area. From 1992 through 2001 in areas outside the United States and Canada, the delineated prospective area expanded at a rate of about 50,000 square miles per year while the explored area grew at the rate of about 11,000 square miles per year. The delineated prospective area established by 1970 contains about 75 percent of the oil discovered to date in the study area. This area is slightly less than 40 percent of the delineated prospective area established through 2001. Maps and graphs show the extension of the delineated prospective area to deepwater areas offshore of Brazil and West Africa. From 1991 through 2000, offshore discoveries accounted for 59 percent of the oil

Phytoremediation is a promising approach for the cleanup of soil contaminated with petroleum hydrocarbons. This study aimed to develop plant-bacterial synergism for the successful remediation of crude oil-contaminated soil. A consortia of three endophytic bacteria was augmented to two grasses, Leptochloa fusca and Brachiaria mutica, grown in oil-contaminated soil (46.8 g oil kg -1 soil) in the vicinity of an oil exploration and production company. Endophytes augmentation improved plant growth, crude oil degradation, and soil health. Maximum oil degradation (80%) was achieved with B. mutica plants augmented with the endophytes and it was significantly (P oil reduction indicates that catabolic gene expression is important for hydrocarbon mineralization. This investigation showed that the use of endophytes with appropriate plant is an effective strategy for the cleanup of oil-contaminated soil under field conditions.

Visual Workflows for Oil and Gas Exploration

KAUST Repository

Hollt, Thomas

2013-04-14

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

Electronic techniques for subsea oil exploration and extraction

Energy Technology Data Exchange (ETDEWEB)

Subsea oil exploration and extraction is becoming increasingly difficult, costly, and dangerous. Electronics is contributing to make offshore work easier and safer. It is used for positioning ships or oil rigs, for remotely controlling well-heads and tool reentry operations, for pipelaying operations, and for monitoring underwater equipment. It is also tending to replace men in diving operations. The specific achievements of THOMPSON--CSF in this field are described. Fully automated operation of the winches on the ETPM 1601 barge proved successful during a recent pipelaying operation. The technique used by THOMPSON--CSF in this venture allowed a single operator to control all the maneuvers. These are briefly described. (MCW)

Modeling Oil Exploration and Production: Resource-Constrained and Agent-Based Approaches

International Nuclear Information System (INIS)

Jakobsson, Kristofer

2010-05-01

Energy is essential to the functioning of society, and oil is the single largest commercial energy source. Some analysts have concluded that the peak in oil production is soon about to happen on the global scale, while others disagree. Such incompatible views can persist because the issue of 'peak oil' cuts through the established scientific disciplines. The question is: what characterizes the modeling approaches that are available today, and how can they be further developed to improve a trans-disciplinary understanding of oil depletion? The objective of this thesis is to present long-term scenarios of oil production (Paper I) using a resource-constrained model; and an agent-based model of the oil exploration process (Paper II). It is also an objective to assess the strengths, limitations, and future development potentials of resource-constrained modeling, analytical economic modeling, and agent-based modeling. Resource-constrained models are only suitable when the time frame is measured in decades, but they can give a rough indication of which production scenarios are reasonable given the size of the resource. However, the models are comprehensible, transparent and the only feasible long-term forecasting tools at present. It is certainly possible to distinguish between reasonable scenarios, based on historically observed parameter values, and unreasonable scenarios with parameter values obtained through flawed analogy. The economic subfield of optimal depletion theory is founded on the notion of rational economic agents, and there is a causal relation between decisions made at the micro-level and the macro-result. In terms of future improvements, however, the analytical form considerably restricts the versatility of the approach. Agent-based modeling makes it feasible to combine economically motivated agents with a physical environment. An example relating to oil exploration is given in Paper II, where it is shown that the exploratory activities of individual

Oil seed marketing prospects

International Nuclear Information System (INIS)

Ceroni, G.

1992-01-01

With its 100 million tonnes annual production, the American continent is by far the world's biggest producer of oil seed, followed by Asia - 52 million, and Europe - 27 million tonnes. The Italian and European Communities have the farming capacity to double their production, but international agreements currently prohibit such initiatives. After first providing a panorama of the world oil seed market, this paper discusses new reforms in European Communities internal agricultural policies which currently limit production. These reforms, intended to encourage the production of oil seed for use as an ecological automotive fuel alternative, call for an obligatory set-aside of 15% of producing farm-land in exchange for the compensatory removal of oil seed production limits

The environmental impact of major oil spills on marine microorganisms has yet to be thoroughly investigated using molecular biology techniques. The Deepwater Horizon (DWH) drilling rig explosion of 2010 affected an approximately 176,000 km 2 surface area of the Gulf of Mexico (GOM) when an estimated 210 million gallons of oil from the Macondo Prospect spilled into the environment. Pelagic Sargassum, a complex of two surface drifting species (Sargassum natans and Sargassum fluitans) of marine brown macroalgae and a critically important habitat in the GOM ecosystem, was suffused by Macondo Prospect 252 oil released during the DWH event. Using 16S rRNA PCR and Roche 454 pyrosequencing, the effect of the oil on the bacterial population associated with pelagic Sargassum and contiguous waters was examined by comparing sequence data generated from samples collected from oiled and non-oiled locations in the northern GOM. Sequence data showed similar microbial composition in Sargassum regardless of exposure to oil primarily dominated by five phyla; Proteobacteria, Bacteroidetes, Actinobacteria, Verrucomicrobia, and unclassified bacteria. The microbial composition in water samples was significantly less diverse than for Sargassum and consisted primarily of Proteobacteria, Firmicutes, and Bacteroidetes. Due to the evenly distributed abundance of microbial species on oiled and non-oiled pelagic Sargassum, study findings indicate that DWH spilled oil had minimal effect on the composition and diversity of the microbial community associated with Sargassum and contiguous waters. However, higher abundances of Sulfitobacter and one species of Psychrobacter were found in oiled water samples when compared to non-oiled water samples indicating some effect of DHW oil in the microbial composition of seawater. Though there are a number of marine studies using molecular biology approaches, this is the first molecular examination of the impact of the DWH oil spill on bacterial communities

Full Text Available This article aims to discuss the main challenges and prospects for the implementation of reverse logistics to lube oil and its packaging. The methodology focuses on conducting in-depth interviews with representatives of these products’ chains, and the results show that technological advances now allow for the generation of re-refined oil with better economic and environmental features than crude oil, and there have been noticeable advances as to packaging too. However, issues such as conflicts in the reverse chain as to the distribution costs of collection, lack of regional solutions to recycling activities, poor supervision, lack of tax incentives and manufacturers’ low interest in modify their products and processes emphasis on prevention challenge the expansion of large-scale reverse logistics activity in the country.

The MENA region is endowed with enormous resources of oil and gas, rendering it the world′s richest region in this regard. Endowment differs from one country to another with few countries are almost dry; however the economic benefits proliferated to almost every country in the region. In spite of some doubts being cast about the amount of proven oil reserves, these with improved technology and new discoveries are increasing year after another. With no long term feasible alternatives to oil for transport and the increasing trade in LNG, the region′s importance as a world′s leading supplier of fossil fuels will continue for decades to come. However, these favourable prospects hide many challenges facing the MENA region, among them is the difficulty in mobilizing investment funds for sustaining and increasing output to feed growing global demand. Growing local demand, due to the proliferation of subsides, is another worrying aspect that already caused few countries with modest resources to become oil importers instead of exporters, with larger exporters decreasing their surplus output. The region is also still mainly dependant on foreign technologies and skilled manpower. Regional cooperation in oil and gas networks and electricity interconnections is still modest. The region has a long history of conflict; correspondingly it is a major importer of armaments which is increasingly eating a lot of its surplus income. With the political and social changes presently taking place in many MENA countries, due to the Arab spring and continuation of local conflicts, the sustainability of supplies from the region are increasingly a source of worry to MENA exporters and its many importers. It is also causing increasing involvement of the super powers in regional affairs. - Highlights: • Global oil and gas reserves and prices. • Energy sustainability and the Middle East. • Energy economics and investments in the Middle East

and gas pools mainly vvithin the Upper and Lower Cretaceous. Recent advances in seismic techniques are helping in locating deeper structures, which might prove instrumental in the upgrading of the oil possibilites of the region. At present, the exploration activities are going on in the different oil and gas provinces in Egypt. These activilles are expected to increase and are also expected to expand to new areas in the eastern part of the Gulf of Suez Basin, offshore and onland, in Northern Sinai and in the Offshore Mediterranean. These new areas are believed to house very good prospects which will be tested not before long. It is also hoped that progress in seismic tools and techniques will add to the possibilities of finding more oil and gas. On connaît des accumulations d'huiles depuis 1868, quelque 10 ans après le célèbre puits de Drake en Pennsylvanie (août 1859. Ces accumulations ont été trouvées comme des suintements dans des tunnels forés pour l'extraction du soufre dans la région de Gemsa sur la côte ouest du golfe de Suez. Depuis cette époque, les activités d'exploration se sont poursuivies à travers une longue histoire d'opérations qui témoignaient des derniers développement dans les outils et les techniques. Jusqu'à maintenant, la principale province à huile d'Egypte est le bassin du golfe de Suez où la majorité des réserves ont été trouvées. D'autres provinces à hydrocarbures sont le bassin du delta du Nil, celui d'Abu Garadig et la ride d'El Alamein, les deux derniers situés dans le désert occidental. Il y a eu trois importantes découvertes de gaz dans le delta du Nil, dont deux en mer, en plus de quelques indices de gaz encore non commerciaux. Outre les découvertes mentionnées, les activités d'exploration au cours de cette longue période ont apporté une masse d'informations géologiques et géophysiques qui ont contribué largement à la connaissance géologique de l'Egypte, et en particulier à la géologie p

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

Innovative options for structuring oil and gas leases and exploration permits on Aboriginal lands

Douglas, W.; Wells, M.

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

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.

2006-11-15

The offshore oil and gas exploration that is currently taking place on Sakhalin Island was discussed, with particular reference to the status of Sakhalin Energy and the challenges facing oil and exportation from the ice covered waters of Russia's Sea of Okhotsk. Sakhalin Energy, an incorporated joint venture of a consortium of companies, completed a feasibility study for oil production off the east coast of Sakhalin Island in December 1992. Sakhalin Energy has two fields, namely the Piltun Astokhskoye and Lunskoye fields. The Piltun Astokhskoye field is currently under production via the Molikpaq platform and the Lunskoye field and northern part of Piltun Astokhskoye field are currently being developed under the Phase 2 project. Since 1999, Sakhalin Energy has been producing oil from a caisson structure drilling rig which was fitted with ice protection shielding around the waterline in order to comply with Russian requirements. Production is via an undersea pipeline to a Single Anchor Leg Mooring (SALM) unit and then to a Floating Storage and Offloading unit (FSO). A brief outline of the structure was presented along with current ice management procedures and arrangements. In order to maximize the length of the production season, ice management is used to enable an early start and a late end to production. It was noted that great care is taken to ensure that the operations in ice are carried out with consideration of the environmentally sensitive area that is home to the endangered Western Gray Whale and Stellar Sea Eagle. 3 refs., 1 tab., 7 figs.

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.

Petroleum exploration in the Paleozoic sedimentary basins of Brazil has proven very challenging for explorationists. Except for the Solimoes Basin, in which transcurrent tectonism formed prospective structural highs, Brazilian Paleozoic basins lack intense structural deformation, and hence the detection and prospecting of place is often difficult. Magmatic intrusive and associated rocks in all these basins have traditionally been considered heat sources and hydrocarbon traps. The role of tholeiitic basic dikes in the generation, migration and accumulation of petroleum in the Anhembi oil occurrence (Sao Paulo State) is discussed herein. It follows that similar geological settings in other Paleozoic basins can be regarded as promising sites for oil accumulation that warrant investigation via modern geological and geophysical methods.

Data Prospecting Framework - a new approach to explore "big data" in Earth Science

Science.gov (United States)

Ramachandran, R.; Rushing, J.; Lin, A.; Kuo, K.

2012-12-01

Due to advances in sensors, computation and storage, cost and effort required to produce large datasets have been significantly reduced. As a result, we are seeing a proliferation of large-scale data sets being assembled in almost every science field, especially in geosciences. Opportunities to exploit the "big data" are enormous as new hypotheses can be generated by combining and analyzing large amounts of data. However, such a data-driven approach to science discovery assumes that scientists can find and isolate relevant subsets from vast amounts of available data. Current Earth Science data systems only provide data discovery through simple metadata and keyword-based searches and are not designed to support data exploration capabilities based on the actual content. Consequently, scientists often find themselves downloading large volumes of data, struggling with large amounts of storage and learning new analysis technologies that will help them separate the wheat from the chaff. New mechanisms of data exploration are needed to help scientists discover the relevant subsets We present data prospecting, a new content-based data analysis paradigm to support data-intensive science. Data prospecting allows the researchers to explore big data in determining and isolating data subsets for further analysis. This is akin to geo-prospecting in which mineral sites of interest are determined over the landscape through screening methods. The resulting "data prospects" only provide an interaction with and feel for the data through first-look analytics; the researchers would still have to download the relevant datasets and analyze them deeply using their favorite analytical tools to determine if the datasets will yield new hypotheses. Data prospecting combines two traditional categories of data analysis, data exploration and data mining within the discovery step. Data exploration utilizes manual/interactive methods for data analysis such as standard statistical analysis and

Biogeochemical anomaly above oil-containing structures in an arid zone. [Growth stimulation of plants by sodium naphthenate used for prospecting

Energy Technology Data Exchange (ETDEWEB)

Grishchenko, O.M.

1983-01-01

Visual biological anomalies above the oil-containing structures are characterized by bright green coloring of the vegetation cover, gigantism of the plants, extended vegetation period of the plants, deformity of the plants, etc. Biological anomalies are associated with geological features and are observed only above the zone of fault disorders of the earth's crust, above deep faults. A conclusion is drawn about the presence above the oil-bearing structures in the arid zone of a biogeochemical anomaly whose origin is explained by the biological activity of oil and its derivatives. The petroleum growth matter is the sodium salt of naphthene acid, a growth stimulator of plants and animals. The oils of the USSR contain 0.8-4.8% naphthene acids, which effuse through the faults into the root area levels of the soil. As a result of stimulation of growth and development by the petroleum growth matter, the vegetation period of the plants is prolonged. Under the influence of natural petroleum growth substances, the height and productivity of the anomalous plants increases 2-3-fold. Formation and manifestation of signs of biogeochemical anomalies above the oil-bearing structures in the arid zone predetermine the following conditions: presence of fault disorders of the earth's crust; salinity of the root area of the soil layer necessary for neutralization of the naphthene acids with subsequent formation of the biologically active naphthenates; aridity of the desert landscape; plain relief excluding color diversity in vegetation cover because of nonuniform wetting, etc. The established biogeochemical anomaly can be used in prospecting and exploration of oil, gas and bitumen, and also in determining the fault disorders of the earth's crust.

Russia's chief oil and gas contractor, Rosneftegazstroy, a joint stock company formed in 1991, took over from the former Soviet Union's Ministry of Oil and Gas Construction and from Neftegazstroy, the State concern. Responsible for the exploration and exploitation of the country's huge oil and gas reserves, Rosneftegazstroy has a mammoth task ahead to modernize and create an adequate infrastructure for its new commercial basis. Its foreign investment projects are described and plans for rebuilding and new developments are discussed. Russia's fuel and energy industries now show clear signs of increasing activity, amid a backdrop of falling production overall. (UK)

Prospects for oil prices

Stevens, P.

1992-01-01

The basic argument presented is that the oil price is set in an administrated market. The administration is undertaken by the controllers of excess capacity to produce crude oil. The extent to which the administrated price matches the market price is a function, first, of the strength and effectiveness of the market controller and, secondly, of the state of supply and demand and expectations in the market. Currently, the market is operating close to capacity, what limited excess capacity exists is located mainly in Saudi Arabia and the Saudi Arabians appear to be following a low price objective. While the Saudi Arabians pursue volume, the short term project, in the balance of a political upheaval, is that oil prices will remain below the $21 per barrel agreed in July 1990. There is a view that Saudi Arabia would take quick action to reverse a price collapse, but attention is drawn to previous miscalculations with respect to price collapse. Should political circumstances allow the return of Iraq to the oil market, then excess capacity within the Gulf members of OPEC will return and control will be much more difficult. (UK)

In accordance with that philosophy are occurring new and important steps to reinforce the oil sector: the amplification of the exploratory frontier by means of the incorporation of a bigger number of sedimentary areas, and the adoption of novel recruiting instruments. It is aware of the competition that exists in the attainment of fresh capitals of risk for the developments of the sector, but, equally optimistic of Colombia offers; the author explains the reach of the change that is giving to the system of oil recruiting, with the purpose of to incentive the exploratory investment and to guarantee to the country the self-sufficiency and the generation of surpluses exportable, bigger economic incentives for exploration of new areas with the purpose of enlarging the exploratory frontier. Stimuli to the exploration with areas that have projection for small fields, and more favorable conditions for the search of natural gas projects in front of the established terms for the petroleum by the govern, among other topics treaties

ALASKA OIL AND GAS EXPLORATION, DEVELOPMENT, AND PERMITTING PROJECT

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

In order to solve the problem of shortage of water resources in northern Shaanxi, we selected rectangular large loop source transient electromagnetic method with high water affinity, and radioactive α measurement method which can delineate the water storage structure, comprehensive geophysical prospecting methods to look for groundwater. Algorithm has established a forward model, and compared all-time apparent resistivity in late-time apparent resistivity is better than late. We can find out the exact location of the groundwater and thus improving wells rate by comparatively using these two kinds of geophysical prospecting method. Hydrogeology drilling confirmed water inflow of a single well can be up to 40 m 3/h, it can fully cover native Domestic and Agricultural water, and provide an important basis for groundwater exploration.

The Asia-Pacific oil market : prospects for Canadian oil

International Nuclear Information System (INIS)

Fesharaki, F.

2004-01-01

The Asia-Pacific region is among the fastest growing oil markets for which analysts predict healthy growth rates due to high energy demands from developing countries such as China. Increased oil demand will mean new refining capacity needs and increased supplies of crude oil. The indigenous crude supply in the Asia-Pacific region is limited and unable to meet the region's needs. Imports are therefore expected to rise continuously. Although the Middle East will continue to be the dominant player in meeting these growing oil needs, Canada has an opportunity to diversify the supply source and play a significant role in meeting the energy needs of the Asia-Pacific region. tabs., figs

Prospects for non-OPEC oil supply

International Nuclear Information System (INIS)

O'Dell, S.

1994-01-01

An International Energy Agency forecast is provided of non-OPEC oil production over a 15-year horizon. Reference-case forecasts are derived from Hubbert-type resource models, official industry announcements about such matters as oil discoveries and development projects, and an oil industry consensus. Separate regional profiles are provided for North America, Europe, the former Soviet Union, and the rest of non-OPEC countries (South America, Asia, non-OPEC Middle East). Under a flat-price scenario ($18/bbl), total non-OPEC oil supply rises slightly from 41.4 million bbl/d (MBD) in 1995 to 41.9 MBD in 2010. Under a scenario in which prices rise to $28/bbl, oil supply rises to 47.5 MBD in 2010. The latter results depend on specific assumptions concerning economic growth, energy prices, the geological potential of some areas which are not yet well understood, technological advances, and the nature of political developments. Uncertainties regarding these assumptions are discussed, with reference to reserves, price responsiveness, world oil industry investment, technology, and costs. A major uncertainty is the issue of investment in the OPEC countries, since the rising-price scenario assumes that OPEC invests only reluctantly. If major OPEC producers choose to open their upstream sectors to international oil companies, the situation will change completely. Otherwise, oil markets are expected to continue to behave in the manner of the past 20 years, with highest-cost oil being developed first while cheaper oil remains in the ground. 8 refs., 10 figs., 3 tabs

Long-run industry performance in exploration outside North America

International Nuclear Information System (INIS)

Bee, A.C.

1991-01-01

Exploration success in the oil and gas business over the long term has not followed a sufficiently consistent pattern to predict the future with any degree of comfort. The study of past industry performance, however, has an important bearing on the future exploration activity. Nationalization of a large part of the major companies' producing assets in the 1970s and 1980s proved to be a turning point for many industry trends, including global finding rates. Supported by a buoyant oil price, the industry moved to explore in the more remote, hostile, and costly environments. This technologically improving exploration is rapidly eating into the accessible acreage. Larger fields are becoming scarcer, and competition to access the most prospective areas is fierce. To meet the anticipated demand for oil and gas, the industry must be increasingly successful in finding large volumes to replace declining reserves from existing giant fields. The successful explorer will not only be measured by annual finding volumes and costs, but also by long-term value creation, which has taken as long as 30-40 years to achieve in any one basin

Latest oil data, trends and prospects

Reserves of crude oil, especially in non-opec areas continue to grow steadily. OPEC, however, remains dominant in the international trade of oil. Oil production, too, is buoyant, with expansion in OPEC running at 0.7% for 1994 and non-OPEC production expansion at 4.2%. Overall demand for oil also rose (by 1.7%), a sharp fall in CIS state consumption notwithstanding. Import dependence continues to grow. Heavy investment by the petroleum industry in production, transportation and processing is expected over the next thirty years. However, oil's share of the world energy mix continues to be eroded by nuclear power, gas and coal, despite adequate supplies. (UK)

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

Directory of Open Access Journals (Sweden)

Lihui Zheng

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.

The purpose of this study is water prospectivity modeling (WPM) for recognizing karstic water-bearing zones by using analyses of geo-exploration data in Kal-Qorno valley, located in Tepal area, north of Iran. For this, a sequential exploration method applied on geo-evidential data to delineate target areas for further exploration. In this regard, two major exploration phases including regional and local scales were performed. In the first phase, indicator geological features, structures and lithological units, were used to model groundwater prospectivity as a regional scale. In this phase, for karstic WPM, fuzzy lithological and structural evidence layers were generated and combined using fuzzy operators. After generating target areas using WPM, in the second phase geophysical surveys including gravimetry and geoelectrical resistivity were carried out on the recognized high potential zones as a local scale exploration. Finally the results of geophysical analyses in the second phase were used to select suitable drilling locations to access and extract karstic groundwater in the study area.

Tendances de l'exploration pétrolière dans les pays en voie de développement Petroleum Exploration Trends in the Developing Countries

Directory of Open Access Journals (Sweden)

Favre J.

2006-11-01

Full Text Available En 1980, l'ensemble des Pays en Voie de Développement (PVD non-OPEP représente 9,3 % de la production de pétrole mondiale et plus de 10 % des réserves prouvées. La position des PVD importateurs de pétrole est plus modeste, avec 2 % de la production mondiale, et seulement 1,2 % des réserves prouvées ; en revanche, leurs réserves de gaz naturel sont légèrement plus importantes et relativement peu exploitées. Compte tenu de la faiblesse de l'exploration dans les PVD non-OPEP, qui s'explique au moins partiellement par des conditions économiques et politiques, leur potentiel en hydrocarbures pourrait être nettement supérieur aux découvertes actuelles, comme le confirment les résultats obtenus dans de nouvelles zones récemment prospectées. Jusqu'à ces dernières années, l'effort d'exploration dans les PVD non-OPEP, mesuré en termes de travaux de sismique et de forage, est resté pratiquement stable ; néanmoins, depuis 1979, on observe une reprise des efforts de prospection, spécialement dans les PVD déjà producteurs, là où sont concentrés 90 % des forages d'exploration entrepris dans les PVD non-OPEP. A l'opposé, depuis la crise de 1973 et ses répercussions sur le prix du pétrole, on enregistre une forte croissance de l'exploration dans les pays industrialisés, spécialement en Amérique du Nord, due à l'attrait économique des découvertes potentielles. Pour favoriser la même intensification de l'exploration dans les PVD, des mesures d'incitation doivent continuer à être proposées. La situation des quelque 70 pays où jusqu'à maintenant l'exploration a été très diffuse et où subsistent des espoirs pétroliers est la plus critique. In 1980, all the non-OPEC LDCs represented 9. 3 percent of world oil production and more than 10 percent of the proved reserves. The position of the oil-importing LDCs was more modest, with 2 percent of world production and only 1. 2 percent of the proved reserves. On the other

Anon.

1991-01-01

This paper reports that prospects of Angola, free of political complications, are certain to bring a flurry of interest from oil firms and could mean an influx of foreign capital. Licensing will be under production-sharing terms, but incentives may be offered due to increased risks inherent in deeper water. Long term security and stability remain uncertain. In addition to Unita and previously communist MPLA, new factions from 16 years of civil war are gaining support and increasing possibilities for violence. Oil firms consider production-sharing terms high and current price cap clauses keep them from realizing benefits from price increases after contracts are signed. However, geology and exploration successes have overshadowed concerns

China Oil and Gas Market Assessment

Qiu, Yu

2004-08-01

China, with one-fifth of the world's population and one of the fastest rates of economic growth, is experiencing a boom in its energy requirements. China has been identified as a high priority market for the oil and gas sector. This priority has resulted in the high level of investment and many large-scale projects related to the oil and gas industry. Oil production from existing fields is expected to increase, new oil and gas fields will be developed, and the country's oil and gas transmission infrastructure will be extended to meet domestic demands. In addition, total domestic investment needs for the next three decades till 2030 are estimated at around $119 billion, and upstream exploration and development will account for about $69 billion. China's oil and gas exploitation business has been the biggest beneficiary of the bearish crude oil prices, national oil stockpile and the need of infrastructure. In the first six-month period of 2005, this industry has gained a profit of USD16.5 billion, up 73.4 per cent year-on-year. The country is becoming increasingly open to international oil companies, contractors and equipment suppliers, who can bring advanced technology, equipment, and management experience. In this context, considerable opportunities in the supply and service sectors are open to Dutch companies. This report analyses the present situation and market prospect of China upstream oil and gas industry, including: Current status of Chinese oil and gas industry analysis and future development forecast; Potential customers analysis, such as three stated-owned oil companies and their foreign partners;Domestic and foreign competitors analysis; Potential opportunities and challenges analysis; Providing contacts and information on main ongoing oil exploration and development projects, and business practices

While mostly undeveloped, tremendous oil resources are found in the largest Central Asian republic, Kazakhstan. Owing to progressive legislation and a determined government, the second largest country of the former USSR is attracting significant investments from overseas energy companies. Continued limited access to global markets may, however, slow future investments unless the existing pipeline network can be expanded. This paper describes current oil exploration and production activities in Kazakhstan, and outlines prospects for future developments. (Author)

Oil shale commercialization study

Energy Technology Data Exchange (ETDEWEB)

Warner, M.M.

1981-09-01

Ninety four possible oil shale sections in southern Idaho were located and chemically analyzed. Sixty-two of these shales show good promise of possible oil and probable gas potential. Sixty of the potential oil and gas shales represent the Succor Creek Formation of Miocene age in southwestern Idaho. Two of the shales represent Cretaceous formations in eastern Idaho, which should be further investigated to determine their realistic value and areal extent. Samples of the older Mesozonic and paleozoic sections show promise but have not been chemically analyzed and will need greater attention to determine their potential. Geothermal resources are of high potential in Idaho and are important to oil shale prospects. Geothermal conditions raise the geothermal gradient and act as maturing agents to oil shale. They also might be used in the retorting and refining processes. Oil shales at the surface, which appear to have good oil or gas potential should have much higher potential at depth where the geothermal gradient is high. Samples from deep petroleum exploration wells indicate that the succor Creek shales have undergone considerable maturation with depth of burial and should produce gas and possibly oil. Most of Idaho's shales that have been analyzed have a greater potential for gas than for oil but some oil potential is indicated. The Miocene shales of the Succor Creek Formation should be considered as gas and possibly oil source material for the future when technology has been perfectes. 11 refs.

The outlook for the world and Australian oil markets

International Nuclear Information System (INIS)

Donaldson, K.; Fok, G.

1996-01-01

Global demand for oil is projected to continue its upward trend to 2000-1, with growth in the transport sector expected to underpin future increases in oil consumption. World oil consumption is projected to be matched by global production, keeping the average annual oil price relatively stable. In many countries, the diversion of oil revenue to other projects is threatening to constrain increases in production capacity, particularly in the OPEC countries. The encouragement of foreign investment in state oil industries is a likely method of easing the constraint. Australian exploration activity is rising steadily with the prospect of stable oil prices, expanding gas markets and the incentives provided by a number of recent discoveries. While the geographical pattern of Australian production has now changed, with Western Australian production exceeding Victoria production, Australia is expected to maintain its position in the world oil market as a significant producer, importer and exporter.

Full Text Available The international crude oil prices started the year 2014 within parameters comparable to those of the precedent year: WTI (USA recorded 92 $/barrel, on the American spot market, considered a minimum value for the last 5 weeks, while Brent (Great Britain had a more stable evolution, on the spot Rotterdam market, staying around a value of 107,50 $/barrel. Despite analysts’ forecasts, which during the last 3 years staked on a lower oil price, as a consequence of the spectacular increase in non-OPEC oil production, namely of shale oil, the international oil price, namely that of Brent, closed each of the last 3 years around the same level, of 108 $/barrel. As for 2014, the great majority of oil analysts estimates again a decline of oil prices, as a result of a significant rise of oil offer globally, which will greatly surpass the demand rise.

Price and prospects for oil: carrying the burden of excess capacity in the 1980s and beyond

Energy Technology Data Exchange (ETDEWEB)

Goldstein, W

1985-12-01

The continuing decline in world oil prices will not be halted in the short term, and prospects for the long run are not encouraging. There is a problem of unprecedented gravity in the surplus capacity of the oil industry. A glut of 10 million bbl/day of crude oil remains unsold, the cohesion of the OPEC cartel is becoming more strained, and a sizeable proportion of refinery plant has been taken off-stream. The basic difficulty is that high interest rates have curbed international capital formation and depressed demand. Upward pressures on the US dollar have been created by the deficit on US domestic and external accounts, and have retarded the recovery of the global economy. Today, the cost of money exceeds the factor price of oil, and the market is highly unstable. The devastating costs of carrying surplus capacity are likely to survive through the 1980s. 6 figures.

ALASKA OIL AND GAS EXPLORATION, DEVELOPMENT, AND PERMITTING PROJECT

2003-11-19

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.

Drilling through Conservation Policy: Oil Exploration in Murchison Falls Protected Area, Uganda

Directory of Open Access Journals (Sweden)

Catrina A MacKenzie

2017-01-01

Full Text Available Approximately 2.5 billion barrels of commercially-viable oil, worth $2 billion in annual revenue for 20 years, were discovered under the Ugandan portion of the Albertine Rift in 2006. The region also contains seven of Uganda's protected areas and a growing ecotourism industry. We conducted interviews and focus groups in and around Murchison Falls Protected Area, Uganda's largest, oldest, and most visited protected area, to assess the interaction of oil exploration with the three primary conservation policies employed by Uganda Wildlife Authority: protectionism, neoliberal capital accumulation, and community-based conservation. We find that oil extraction is legally permitted inside protected areas in Uganda, like many other African countries, and that the wildlife authority and oil companies are adapting to co-exist inside a protected area. Our primary argument is that neoliberal capital accumulation as a conservation policy actually makes protected areas more vulnerable to industrial exploitation because nature is commodified, allowing economic value and profitability of land uses to determine how nature is exploited. Our secondary argument is that the conditional nature of protected area access inherent within the protectionist policy permits oil extraction within Murchison Falls Protected Area. Finally, we argue that community-based conservation, as operationalized in Uganda, has no role in defending protected areas against oil industrialisation.

Oil and development

Energy Technology Data Exchange (ETDEWEB)

Ellis, F

1974-10-01

The shift in world income due to the increase in oil prices has resulted in a world economy that has been thrown off balance. Nine papers are presented that explore the background and the main implications of this ''watershed'' in international relations, particularly the extent to which it will affect the development prospects of poor countries and the climate of trade between poor and rich nations in the next few years. Two papers, ''Diary of Events in the Oil Market 1971--1974'' and ''Statistical Background,'' provide information on the financial changes implied by the price increase; some of the figures should be treated as preliminary estimates only. ''Large International Firms in the Oil Industry'' examines the part played by the major oil companies in developments in the oil market leading up to the events of 1973. Two papers, ''Can OPEC Maintain Current Prices'' and ''OPEC As a Model for Other Mineral Exporters,'' present optimistic conclusions, from the viewpoint of developing countries, on their future capability for controlling their own destinies in trade. ''A Note on Some Issues Raised for Science and Technology Policy by the Increase in Oil Prices'' looks at options open to producers and consumers of raw materials. ''Assessing the Economic Impact on Developing Countries and Some Policy Suggestions,'' ''A Note on the Implications of the Oil Price Increases for British Aid Policy,'' and ''Confrontation Versus Co-operation'' are three papers concerned with difficulties of developing countries and particularly India, Bangladesh, and Sri Lanka.

Anon.

1991-01-01

This paper reports that Viet Nam is on its way up in the petroleum world. After years of international isolation, the country is poised for a flurry of exploration by international oil companies in the early 1990s. Viet Nam has joined the Soviet Union as the only members of the now dissolved, formerly Moscow dominated, 10 nation Council for Mutual Economic Assistance (CMEA) that are self-sufficient in oil production. Moreover, Viet Nam has far outstripped neighboring China, which was not a CMEA member, in offshore oil flow even though China has a much larger Outer Continental Shelf. Prospects are that Viet Nam will continue to lead China in offshore oil production until 1995 at least

Offshore oil: Correctness of perspective

International Nuclear Information System (INIS)

Burns, R.F.

1993-01-01

Except for the Gulf of Mexico, the offshore oil industry has been virtually banned from the US Exclusive Economic Zone for ten years. The oil potential in Alaska's Arctic National Wildlife Refuge (ANWR) is also off limits. The Gulf of Mexico is the only place with prospects for future success and a number of companies both large and small are determined to move forward. The depressed price of oil does not encourage development but recently gas prices in the US have increased, making offshore gas development more feasible. Perhaps most significant is development and application of new technology and more intense management to make sure it works. The offshore oil companies and support industries have made significant technological advances, expending over and above the dollars paid in taxes, lease fees, and royalties. The ocean industries harbor a great reservoir of high technology knowledge. They have demonstrated the ability to successfully meet a vast array of challenges in exploring for, drilling, and producing oil and gas in extreme conditions. These facts beg the question as to the rational basis of each and every regulation and the ban on drilling

The oil barrel price

Blondy, J.; Papon, P.

2009-01-01

This paper proposes an overview and a prospective glance on the oil barrel price. It indicates the relevant indicators: Brent quotation, euro/dollar parity, economic activity indicators, world oil consumption distribution, crude oil production, refining capacity. It briefly presents the involved stake holders: crude oil producers, oil refiners, refined product dealers, and the OPEC. It discusses the major retrospective trends: evolution in relationship with geopolitical events and energy policies, strong correlation between oil demand and economic growth, prevalence of OPEC, growing importance of national oil companies. An emerging trend is noticed: growing role of emerging countries on the crude market. Some prospective issues are discussed: duration and intensity of economic recession, separation between economic growth and energy consumption, pace and ambition level of policies of struggle against climate change, exploitable resources, and geopolitical hazards. Four evolution hypotheses are discussed

The Nigerian experience in health, safety, and environmental matters during oil and gas exploration and production operations

International Nuclear Information System (INIS)

Oyekan, A.J.

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

Oil sands and heavy oil development issues and prospects under a Liberal government

International Nuclear Information System (INIS)

Shiry, J.

1993-01-01

A short review is presented of some of the factors affecting development of the western Canadian oil sands and heavy oil deposits to the year 2000. The Alberta oil sands resource has at least 1 trillion bbl of recoverable oil. At current prices, technology is the key to reducing costs to a more economic level. Cash operating costs have halved to $15/bbl over the past decade and the oil sands companies have programs to halve that figure again. A problem is the rising cost of natural gas as a fuel, which could jeopardize further development of both oil sand and heavy oil resources. In Saskatchewan, over 25 billion bbl of heavy oil are estimated to be in place. The biggest question is what percentage can be recovered; again, technology such as horizontal wells, 3-dimensional seismic, and steam assisted recovery is playing an important role. Concerns are expressed about the intentions of the new Liberal government concerning oil sand/heavy oil development, especially on the issues of foreign investment, exports, and environmental policy. A Liberal energy policy is not likely to allow U.S. direct investment in an oil sands plant to be tied to export of production, and the energy- and emissions-intensive nature of the oil sand/heavy oil industry will tend to make environmental approvals difficult

Radioactive Waste in Oil Exploration

International Nuclear Information System (INIS)

Landsberger, S.; Graham, G.

2014-01-01

Naturally occurring radioactive material commonly known as NORM composes the majority of the dose received by a person each year at approximately 80% of the total amount. However, there is a noticeably higher concentration of radioisotopes present in technologically enhanced NORM, often called TENORM, which results directly from human industrial activities. NORM is formed in the process of mineral mining including phosphate production, where the end goal is to concentrate high quantities of metals or elements (e.g. phosphorous). However, NORM has also become a widely recognized problem in the oil and gas industry. It is approximately one hundred and fifty years since oil was discovered in the continental United States and the mention of radioactivity in mineral oils and natural gases occurred in 1904, just eight years after the discovery of radioactivity by Henri Bequerel in 1896. In just over three decades the problems from naturally occurring radioactive material (NORM) wastes arising from the oil and gas industry have been much more scrutinized. In the 1980’s 226Ra began to be noticed when scrap metal dealers would detect unacceptably high levels of radiation from oil-field piping1. In 1991 Raloff2 published an article on the new hot wastes in NORM and in 1992 Wilson et. al3 described the health physics aspects of radioactive petroleum piping scale. NORM will develop in high concentrations in by-product oil and gas waste streams4-7. The NORM will chemically separate from other piped material in the process of the extraction of oil, resulting in high concentrations of 226Ra, 228 Ra and 210Pb and other radioisotopes in a densely caked layer on the inner surfaces of the piping1 . The activity of the 226Ra from NORM ranges from 185 to several tens of thousands Bq/kg of sample. By comparison, the NORM concentrations of radium in rock and soil is, at a natural level, 18.5 - 185 Bq/kg1. Disposal of NORM becomes more problematic as higher concentrations of

Discussion on the exploration & development prospect of shale gas in the Sichuan Basin

Directory of Open Access Journals (Sweden)

Dazhong Dong

2015-01-01

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.

TAG Oil hunting elephants in New Zealand

International Nuclear Information System (INIS)

Anon.

2005-01-01

Calgary-based TAG Oil is an exploration company that manages 4.1 million acres of major producing oil and gas fields in New Zealand. The enormous Maui field, with 4 tcf of natural gas in place, has dominated the gas market in New Zealand by meeting nearly 90 per cent of the country's energy demand at costs much lower than world prices. However, the maturing field is in decline and will cease production by 2008. New gas field discoveries will only meet 60 per cent of the country's energy requirements for 5 additional years. Unless new large reserves of gas are discovered, the supply and demand situation will get worse. Lead time to place new production on-stream requires 5 to 10 years, which creates a large supply gap over the next decade. Public resistance to coal-fired power plants, new hydroelectric dams and nuclear power has left the country with no viable alternative to natural gas. TAG Oil has taken this unique opportunity to create value when gas demand is at its maximum and energy alternatives are at a minimum. This paper presented 8 reasons why New Zealand is a good place for petroleum investment. Most exploration has occurred in the Taranaki Basin, where only 130 exploration wells have been drilled. The rest of the sedimentary basins are essentially unexplored, although many exhibit oil seeps and have hydrocarbon potential. In 1998, an onshore gas discovery was made on the East Coast Basin. Sub-commercial discoveries have also been made in the offshore Canterbury and Great South basins. TAG Oil is focusing on shallow oil and gas pools in the Miocene reservoirs at Taranaki, as well as on deeper gas prospects in Tariki and Kapuni Sands. One of the challenges was a shortage of drilling rigs, so TAG is having a rig built in Calgary and shipped south. 2 figs

Canada's east coast offshore oil and gas industry: a backgrounder

Bott, R.

1999-06-01

Another of the backgrounder series published by the Petroleum Communication Foundation, this booklet describes Canada's offshore oil and natural gas operations in the North Atlantic Ocean, specifically in the Hibernia (off Newfoundland, crude oil), Terra Nova (off Newfoundland, crude oil), Cohasset-Panuke (off Nova Scotia, crude oil) and Sable Island (off Nova Scotia, natural gas) fields. Together, these project represent an investment of more than 10 billion dollars and constitute a growing portion of Canada's 400,000 cubic metres of crude oil and natural gas liquids per day production. The booklet explains the importance of the offshore oil and natural gas industry to Canada, the benefits accruing to the maritime provinces locally, prospects for future offshore oil and natural gas development and provides a brief summary of each of the four current major projects. The booklet also provides an overview of the facilities required for offshore energy projects, environmental impacts and safeguards, exploration, drilling, production, processing and transportation aspects of offshore oil and gas projects. 9 refs, photos

Net energy yield from production of conventional oil

International Nuclear Information System (INIS)

Dale, Michael; Krumdieck, Susan; Bodger, Pat

2011-01-01

Historic profitability of bringing oil to market was profound, but most easy oil has been developed. Higher cost resources, such as tar sands and deep off-shore, are considered the best prospects for the future. Economic modelling is currently used to explore future price scenarios commensurate with delivering fuel to market. Energy policy requires modelling scenarios capturing the complexity of resource and extraction aspects as well as the economic profitability of different resources. Energy-return-on-investment (EROI) expresses the profitability of bringing energy products to the market. Net energy yield (NEY) is related to the EROI. NEY is the amount of energy less expenditures necessary to deliver a fuel to the market. This paper proposes a pattern for EROI of oil production, based on historic oil development trends. Methodology and data for EROI is not agreed upon. The proposed EROI function is explored in relation to the available data and used to attenuate the International Energy Agency (IEA) world oil production scenarios to understand the implications of future declining EROI on net energy yield. The results suggest that strategies for management and mitigation of deleterious effects of a peak in oil production are more urgent than might be suggested by analyses focussing only on gross production. - Highlights: → Brief introduction to methodological issues concerning net energy analysis. → Description of EROI function over the whole production cycle of an energy resource. → Calibration of this function to EROI data from historic oil production. → Application to determine the net energy yield from current global oil production. → Calculation of net energy yield from IEA projections of future oil production.

Oil and power: Iraq at the crossroads

International Nuclear Information System (INIS)

Enay, P.

1995-11-01

Oil and Power: Iraq at the Crossroads is the first analysis which specifically addresses the oil sector in Iraq. It provides a detailed account of the present Iraqi oil infrastructure and assesses the risks and opportunities facing those who seek to invest in its redevelopment. The report examines the implications for the world oil markets of Iraq's ambitious plans to expand production capacity to 6m barrels per day -almost twice its pre-war peak. It explains in clear, authoritative terms the profound problems confronting Iraq's oil sector and the prospects for rebuilding it. It analyses expertly and in detail the current regime's chances of survival and examines the alternative contenders for power -and their likely attitudes towards co-operation with foreign oil interests. The report examines and explains: Iraq's oil infrastructure, from fields under exploration to nominal administrative structure; the effect on oil prices of Iraq's eventual re-entry into the oil market; the facilities in need of repair and where the shortage of spares and human expertise are; the unofficial decision-making structure in the oil sector; the short- and medium-term impact of economic disintegration on oil development policy; the effects of UN sanctions and the motives of those supporting or opposing sanctions; the likely impact of prevailing economic constraints on Iraqi oil and the historical role of commissions in Iraqi oil contracts; the political impact of General Hussein Kamal Hassan's defection and the Kurdish and Shi'ite threats to Iraqi national unity.

Constraints and prospects of uranium exploration in Himalaya

International Nuclear Information System (INIS)

Singh, Rajendra

1994-01-01

Exploration for uranium in the Himalaya over the last thirty years has brought to light five distinct types of mineralisation, namely, vein-type, hydrothermal shear controlled-type, disseminated-type, syngenetic-type, and sandstone-type. The first three are associated with lower to middle proterozoic metasedimentary rocks, metabasic rocks, and granitoids of the lesser Himalaya in close proximity to the main central thrust (MCT). The carbonaceous slates of Haimanta group (late proterozoic to eocambrian) and the Mussoorie phosphorites (eocambrian) represent the syngenetic types. The sandstone-type is associated with the late tertiary Siwaliks of the northwestern Himalaya. The constraints in geology and uranium exploration in the Himalaya have been briefly discussed and principal uranium occurrences in relation to their tectonic environment and genesis listed. The need for geochemical characterization of the Himalayan granitoids and the metabasics related to known uranium mineralisation and new areas have been suggested. Integrated application of radiometric, geochemical and geophysical methods of prospecting and remote sensing techniques in regional geological correlation, identification of subtle rock alterations associated with mineralized zones, geologic structures, and deep crustal lineaments have been advocated. A case for the exploration of the areas of lesser Himalaya outside the MCT has been made out so as to locate hitherto unknown types of uranium deposits including, strata bound, metamorphic, and intra granitic types, possibly with better depth persistence.

Prospects for world oil supply

International Nuclear Information System (INIS)

Esser, R.W.

1991-01-01

Surprises lie ahead for world oil supplies, which are expected to increase rapidly throughout the 1990s before leveling off by the end of the century. The extent of this increase could be the major surprise of the decade. Large increases in the capacity in Gulf countries accompanied by smaller increases in the non-Middle East OPEC countries will be augmented by a gradual increase in non-OPEC capacity into the late 1990s. By 2000, declining capacity in the latter two areas will offset continued capacity increases in the Gulf countries. Overall capacity in the non-OPEC countries (excluding China, Eastern Europe, and the Soviet Union), is expected to increase by 1.1 million BOPD from the low point in the early 1990s to a mid 1990s peak. The increase will be led by a large increase in capacity from the United Kingdom and smaller contributions from the non-Middle East OPEC countries and Mexico. In the forecast, emphasis has been placed on a detailed evaluation of recent significant discoveries made in non-OPEC countries and non-Middle East OPEC countries since 1983, which when taken together, are expected to add 8 million BOPD new capacity as soon as 1995. These discoveries have taken place in both existing and evolving exploration hotspots that are expected to receive increasing industry emphasis in the 1990s

The major factors that have influenced price developments are briefly discussed. The future course of oil prices and the supply/demand fundamentals that are likely to influence them will be reviewed in the light of OPEC producers' quest for stability in the market and the maintenance of the role of oil in the energy spectrum. The environment and climate change debate is likely to influence development in the energy and oil markets for a long time to come. Its impact on oil demand is thus discussed, together with its implication for oil prices. (author)

Olive oil is well known for its cardioprotective properties; however, epidemiological data showing that olive oil consumption reduces incident CHD events are still limited. Therefore, we studied the association between olive oil and CHD in the European Prospective Investigation into Cancer and Nutrition (EPIC) Spanish cohort study. The analysis included 40 142 participants (38 % male), free of CHD events at baseline, recruited from five EPIC-Spain centres from 1992 to 1996 and followed up until 2004. Baseline dietary and lifestyle information was collected using interview-administered questionnaires. Cox proportional regression models were used to assess the relationship between validated incident CHD events and olive oil intake (energy-adjusted quartiles and each 10 g/d per 8368 kJ (2000 kcal) increment), while adjusting for potential confounders. During a 10·4-year follow-up, 587 (79 % male) CHD events were recorded. Olive oil intake was negatively associated with CHD risk after excluding dietary mis-reporters (hazard ratio (HR) 0·93; 95 % CI 0·87, 1·00 for each 10 g/d per 8368 kJ (2000 kcal) and HR 0·78; 95 % CI 0·59, 1·03 for upper v. lower quartile). The inverse association between olive oil intake (per 10 g/d per 8368 kJ (2000 kcal)) and CHD was more pronounced in never smokers (11 % reduced CHD risk (P = 0·048)), in never/low alcohol drinkers (25 % reduced CHD risk (P culinary use of olive oil within the Mediterranean diet to reduce the CHD burden.

2002-01-01

The integration and expansion of world oil markets was the main topic of this conference which featured 18 presentations dealing with developments in the international energy sector. The conference provided an opportunity for participants to discuss issues regarding oil supply and demand, oil prices, OPEC's spare capacity, OPEC's view regarding increasing competition from Canada's oil sands, and what role non-conventional oil plays in today's marketplace. The conference was divided into 6 sessions entitled: (1) oil prices, business as usual, (2) world oil demand, the incredible shrinking market, (3) global oil supplies, (4) going offshore, (5) the politics of oil, and (6) the growing North American supply. The outlook of world energy markets was reviewed with particular emphasis on prospects for oil supply and reserves. Also, the current status of the petroleum industry in both OPEC and non-OPEC oil exporting countries was discussed with reference to exploration, production, reserves, and hydrocarbon potential as well as the environmental, and socio-economic challenges that the industry must face. refs., tabs., figs

2012-07-01

The Canadian Association of Petroleum Producers forecast published in 2011 predicts that oil production from oil sands will increase by 50% in the next 3 years and double by 2020. This rate of growth will result in significant pressure on water resources; water use per barrel of oil sands production is comparable to other energy resources - about 2.5 barrels of fresh water per barrel of oil produced are used by mining operations and 0.5 barrels by in-situ operations. Suncor Energy Inc. (Suncor) was the first company to develop the oil sands in northern Alberta and holds one of the largest oil sands positions in Canada. In 2010, Suncor announced plans to increase production to more than 1 million barrels of oil equivalent per day by 2020, which it plans to achieve through oil sands production growth of approximately 10% per year. Because water supply and potential impacts to water quality are critical to its future growth, in 2010-2011 Suncor conducted a risk assessment to identify water-related business risks related to its northern Alberta operations. The assessment identified more than 20 high level business risks in strategic water risk areas including water supply, water reuse, storm water management, groundwater, waste management and river water return. The risk assessment results prompted development of a strategic roadmap to guide water stewardship across Suncor's regional operations. The roadmap describes goals, objectives, and specific activities for each of six key water risk areas, and informs prioritization and selection of prospective water management activities. Suncor is not only exploring water within its own boundaries, but is also collaborating with other oil sands producers to explore ways of integrating its water systems through industry consortia; Suncor is a member of the Oil Sands Leadership Initiative and of the recently formed Canadian Oil Sands Innovation Alliance, among others.

The end of cheap oil: Current status and prospects

International Nuclear Information System (INIS)

Tsoskounoglou, Miltos; Ayerides, George; Tritopoulou, Efi

2008-01-01

This paper, analyses the factors impacting the price of crude oil in order to examine the likely evolution of the oil market and attempts to answer the question, whether cheap oil is already a thing of the past. Based on data made publicly available mostly by the major oil companies, it examines the effects of demand and supply, the evolution of world oil reserves, the trends in new discoveries of new oilfields, the evolution of world Gross Domestic Product (GDP), and the depletion of oil resources. The analysis concludes that the world peak in conventional oil production-the point beyond which oil production will irreversibly start declining-is approaching and will be reached, even according to the most optimistic scenarios, before 2040 and quite possibly much sooner. If the appropriate solutions for substituting crude oil and for conserving the use of energy are not implemented in time, then the current upward trend in oil prices is bound to continue

Cooperation between Russia and Vietnam in Oil and Gaz Industry

Full Text Available The article deals with the problems and prospects of Russian-Vietnamese strategic partnership in the oil and gas industry as an example a 30-year practice of «Vietsovpetro». Exploration and production of oil and gas remains to be the most important part of economic and trade relations between two countries. Signed agreement extends the activities of «Vietsovpetro» until 2030, and projects of Russian companies Lukoil, Gazprom and TNK-BP suggests that Russia has managed to interest the Vietnamese side to continue the mutually beneficial cooperation. However, current international realities require the ongoing development of promising new projects, including investment.

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

Big questions cloud Iraq's future role in world oil market

International Nuclear Information System (INIS)

Tippee, B.

1992-01-01

This paper reports that Iraq raises questions for the world oil market beyond those frequently asked about when and under what circumstances it will resume exports. Two wars since 1981 have obscured encouraging results from a 20 year exploration program that were only beginning to come to light when Iraq invaded Kuwait in August 1990. Those results indicate the country might someday be able to produce much more than the 3.2 million b/d it was flowing before a United Nations embargo blocked exports. If exploratory potential is anywhere near what officials asserted in the late 1980s, and if Iraq eventually turns hospitable to international capital, the country could become a world class opportunity for oil companies as well as an exporter with productive capacity approaching that of Saudi Arabia. But political conditions can change quickly. Under a new, secular regime, Iraq might welcome non-Iraqi oil companies and capital as essential to economic recovery. It's a prospect that warrants a new industry look at what the country has revealed about its geology and exploration history

Biotechnology in breeding of industrial oil crops - the present status and future prospects

Energy Technology Data Exchange (ETDEWEB)

Friedt, W.

1988-02-01

With increasing 'overproduction' of food supplies it is frequently emphasized now that agricultural production of industrial 'non-food' raw materials should be intensified. Many adapted crop plants are already available for producing various kinds of natural materials. Particularly the large group of oil-crops could be used even more widely for providing vegetable oils. The example of rape-seed (Brassica Napus) clearly demonstrates that the composition of vegetable oil can be completely reconstructed according to the wishes of manufacturers or consumers, even by conventional breeding methods. Rapid and efficient breeding is expected by application of modern 'biotechnology'. Where variation for a character like oil-quality is limited within a crop plnt, a wide range of alien wild species is available for broadening genetic variation of plants like rapeseed, sunflower (Helianthus annuus) or linseed (flax, Linum usitatissimum). Exploration of such 'new' genetic variation is nowadays facilitated by in vitro embryo culture or cell (protoplast)-fusion techniques. Such biotechniques can help to overcome crossing barriers between species (genus Brassica). In other important oilcrops like linseed or sunflower, biotechniques can now be applied profitably. Protoplasts can be regenerated in Linum, so that asexual interspecific hybrids can principally be produced in that way. Alien species of sunflower and lineseed show a wide range of variation regarding agronomically important characters, particularly of oil composition and disease resistance. This alien genetic variation can be used for breeding new disease resistant oil-crop cultivars. Other techniques, like the 'haploidy-method' can help to accelerate a breeding programme, ultimately leading to a homozygous line or cultivar.

A Critical Review of the Oil and Tar Sands of the Dahomey Basin

International Nuclear Information System (INIS)

Osundina, A.; Mustapha, A.; Nzewi, T.

2002-01-01

The Benin Basin previously referred to as the Dahomey embayment has been designated as a frontier basin within Nigeria due to its potentially high prospects, but comparatively low exploitation campaign to date. The basin offers a promising opportunity for heavy oil exploration in a narrow belt extending westward from Edo State to the republic of Benin; while offshore, there are high prospects for finding more conventional hydrocarbon.The eastern Dahomey embayment is known to have an extensive reserve of hydrocarbons (bitumen and tar sands). The sediments occur in a 5 8 km belt stretching 120km from the fringes of Lagos State through Ogun, Ondo and Edo States. The estimated reserve potentials exceed 30 billion barrels of oil equivalent.Recently acquired seismic data in OPL 309 and 310, and subsequent drilling of 2 wells on the narrow continental shelf, have shown the presence of closed structures over Basement Highs and other related structural styles in the basin and confirm that conventional light oils and condensates hydrocarbons occur in commercial quantity. These hydrocarbons are reservoired in stratigraphic sequences of Albian Cenomanian age.This paper hopes to expose the hidden riches of this Basin and hopefully get the attention of the big players in refocusing their interests in the basin that attracted attention of the early petroleum explorers to Nigeria approximately 100 years ago

Perestroika, Soviet oil, and joint ventures

Glaznost, the freedom of expression in both the public and private sectors of the Soviet Union, has rapidly transformed the country form a largely isolated and closed society to one that is rapidly becoming more cosmopolitan and open to the West. Now that the Soviet Union is moving toward a free-market economy, a number of new laws are being generated to create a favorable environment for Western investment, especially joint ventures. First, crude oil sales have provided over 75% of much-needed hard currency, and oil has been the principal barter for manufactured goods produced in eastern Europe. Second, joint oil ventures with Western companies can reverse declining production levels and provide sufficient stimulus to turn around the economic recession. The Soviet Union has a very large inventory of discovered but undeveloped oil and gas fields. Most of these fields are difficult for the Soviets to produce technically, financially, and environmentally safely, and they are actively seeking appropriate Western partners. From an exploration point of view, the Soviet Union has probably the largest number of undrilled and highly prospective oil basins, which may replenish declining reserves in the West. Finally, the Soviet Union represents in the long term a large unsaturated market eager to absorb the surplus of goods and services in the Western world. Again, joint oil ventures could provide the convertible currency to increase East-West trade

The prospects of the integrated processing of the high-parameter geothermal resources of the East Ciscaucasia of artesian basin (ECAB) with the conversion of their heat energy into electric energy at a binary geoPP and the subsequent extraction of solved chemical compounds from thermal waters are evaluated. The most promising areas for the exploration such resources are overviewed. The integrated exploration of hightemperature hydrogeothermal brines is a new trend in geothermal power engineering, which can make it possible to significantly increase the production volume of hydrogeothermal resources and develop the geothermal field at a higher level with the realization of the energy-efficient advanced technologies. The large-scale exploration of brines can solve the regional problems of energy supply and import substitution and fulfill the need of Russia in food and technical salt and rare elements. The necessity of the primary integrated exploration of the oil-field highly mineralized brines of the South Sukhokumskii group of gas-oil wells of Northern Dagestan was shown in view of the exacerbated environmental problems. Currently, the oil-field brines with the radioactive background exceeding the allowable levels are discharged at disposal fields. The technological solutions for their deactivation and integrated exploration are proposed. The realization of the proposed technological solutions provides 300 t of lithium carbonate, 1650 t of caustic magnesite powder, 27300 t of chemically precipitated chalk, 116100 t of food salt, and up to 1.4 mln m3 of desalinated water from oil-field brines yearly. Desalinated water at the output of a geotechnological complex can be used for different economic needs, which is important for the arid North Caucasus region, where the fresh water deficiency is acute, especially in its plain part within the ECAB.

Exploration of process parameters for continuous hydrolysis of canola oil, camelina oil and algal oil

Wang, Weicheng

2012-07-01

Thermal hydrolysis of triglycerides to form free fatty acid (FFA) is a well-established industry practice. Recently, this process has been employed as a first step in the production of biofuels from lipids. To that end, batch and continuous hydrolysis of various feedstocks has been examined at the laboratory scale. Canola, the primary feedstock in this paper, camelina and algal oils were converted to high quality FFA. For the different reaction temperatures, the continuous hydrolysis system was found to provide better yields than the laboratory batch system. In addition, CFD simulation with ANSYS-CFX was used to model the performance and reactant/product separation in the continuous, counter-flow reactor. The effects of reaction temperature, water-to-oil ratio (ratio of water and oil volumetric inflow rate), and preheating of the reactants were examined experimentally. Optimization of these parameters has resulted in an improved, continuous process with high mass yields (89-93%, for reactor temperature of 260°C and water-to-oil ratio of 4:1) and energy efficiency (76%, for reactor temperature of 250°C and water-to-oil ratio of 2:1). Based on the product quality and energy efficiency considerations, the reactor temperature of 260°C and water-to-oil ratio of 4:1 have provided the optimal condition for the lab scale continuous hydrolysis reaction. © 2012 Elsevier B.V.

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.

Allen, D.C.K.

1997-01-01

The Australian oil and gas exploration and production industry entered 1997 with high expectations and the promise of significant further discoveries and potential developments. This optimism is based on the results from a busy 1996 in which more exploration wells were drilled than any year since 1991. Offshore seismic acquisition, which is an indication of the future health of the industry, also increased almost four times; onshore, slightly less seismic than the previous year was recorded. Major projects and future prospects are highlighted. It is estimated that for many of these projects to eventuate it will be necessary for world wide gas demand to increase significantly and for oil and gas prices to improve and for the markets and economies in India and China (potential large markets) to mature

Buying versus exploring for reserves in the Canadian oil industry

International Nuclear Information System (INIS)

Sayer, F.

1992-01-01

The issue of a business strategy for Canadian oil companies focussed on either buying reserves or on exploration is examined. A measurement of the amount of merger and acquisition (M ampersand A) transactions vs the amount of exploration activity shows that the number of M ampersand A transactions has risen from 262 in 1989 to an estimated 1,500 in 1992. This sales activity has partly resulted from major companies selling assets to pay down debt. In the same period, the number of licensed exploration wells has decreased from 2,800 to 1,500. An analysis of statistics on the costs of acquisitions vs cost of finding and development shows acquisitions costs are lower in all cases. In addition, the median acquisition price has been falling steadily. Buying reserves has other advantages, including the fact that reserves can be added more quickly, lower risk, and readily available financing. Exploration, however, has its advantages, including the potential for very large reserve additions, higher tax deductions and incentives available, less competition from the industry, and low input costs. The acquisition vs exploration strategies are illustrated using the stock performance of two companies. If the acquisitions trend continues, there will be increases in the profitability of existing reserves, the number of companies, and tax receipts, However, in the long term there will be a drop in Canadian reserves and a significant reduction in the size of the industry. 14 figs., 2 tabs

Globalization and the uneven application of international regulatory standard : the case of oil exploration in Nigeria

Energy Technology Data Exchange (ETDEWEB)

Adalikwu, J.

2008-07-01

This study was conducted to increase the awareness of the current economic situation that exists in the Niger Delta, a region that has been devastated by the activities of oil multinational corporations (MNCs). In particular, the study linked the Obelle and Obagi communities to the political economy of global capital which creates inequalities that divide societies into hierarchies of the rich and poor. The strategies adopted by the people to improve the negative consequences of oil exploration in the communities were also examined. The researcher postulated that there is a relationship between the uneven application of international and national regulations in oil production by MNCs and environmental degradation. A critical ethnographic paradigm was used to explore and explain the processes of globalization that affect the people's lives and means of livelihood. Data were collected and analyzed using both qualitative and quantitative methods. Data was then analyzed using several methods, such as statistics based on cross-tabulation, analysis of themes that emerged from interviews, and Atlas.ti 5.0 qualitative analysis computer programme to show the relationship between variables that emerged from the study. The study revealed that resource exploitation by oil MNCs in Obagi/Obelle communities of the Nigeria Delta, together with the Nigerian government, has resulted in economic expropriation, political disenfranchisement, social instability and environmental damage.

With a proven capacity to identify oil slicks in offshore regions, RADARSAT-1 imagery can be useful for oil exploration purposes. The paper discusses the seepage detection method at Campos Basin, offshore Rio de Janeiro State, which is responsible for 80% of the Brazilian production of oil and gas. It is known that the horizontal migration of petroleum can occurs over tens or even hundreds of kilometers, where the source rock placed in more deep locations can be linked with shallow reservoirs or traps and even reach the ocean. It means that seepage can provide information for risking petroleum charge at basin scales, and cannot have a direct relation with the geographical position of the interpreted seeps and possible filled prospects. A good understanding of the geology, and hence the petroleum systems of a basin is the key to use seepage in exploration. The work is divided into three main steps. First step were select oil seepages interpreted at Campos Basin where is found several giant petroleum fields. Second, the geology of the study area and its structural and stratigraphic features were analyzed, in order to identify possible migration pathways related to faults generated by halokinesis. Another important aspect is the presence of 'windows' or ducts in the evaporates beds allowing the contact between the section that contains source rocks and the turbidities reservoirs, that contain the majority of the oil discovers. All these features were interpreted based on a regional dip seismic line (203 - 76), and a geologic cross section with E-W orientation, showing the structure of the Marlim Field. Finally, all the information was integrated in a Geographical Information System (GIS), and then analyzed in an interdisciplinary environment, with the intention to link possible routes of oil migration to post-evaporites reservoirs or to interpreted seeps.

This circular presents a summary of the geographic location, amount, and results of petroleum exploration, including an atlas showing explored and delineated prospective areas through 1990. The data show that wildcat well drilling has continued through the last decade to expand the prospective area by about 40,000 to 50,000 square miles per year. However, the area delineated by 1970, which represents only about one-third of the prospective area delineated to date, contains about 80 percent of the oil discovered to date. This discovery distribution suggests that, from an overall prospective, the industry was successful in delineating the most productive areas early. The price increases of the 1970's and 1980's allowed the commercial exploration and development of fields in high-cost areas, such as the North Sea and Campos Basin, Brazil. Data on natural-gas discoveries also indicate that gas will be supplying an increasing share of the worldwide energy market. The size distribution of petroleum provinces is highly skewed. The skewed distribution and the stability in province size orderings suggest that intense exploration in identified provinces will not change the distribution of oil within the study area. Although evidence of the field-growth phenomenon outside the United States and Canada is presented, the data are not yet reliable enough for projecting future growth. The field-growth phenomenon implies not only that recent discoveries are substantially understated, but that field growth could become the dominant source of additions to proved reserves in the future.

Long-term prospects for oil market stability

Energy Technology Data Exchange (ETDEWEB)

Subroto, Dr [OPEC, Vienna (AT)

1989-10-01

OPEC recognize that energy consumption has its social costs and benefits, and that some energy sources impose fewer costs on society. We must consider the environmental implications of oil extraction. Our policies today should enable future generations to secure their energy needs, and OPEC is well-positioned to supply them. An inward-looking OPEC, distracted by internal wranglings and inconsistencies, cannot expect to be a stabilizing force in the oil markets. We have sought, therefore, to put our own house in order. Aside from the debate on depletion policy, a major strain on OPEC stability is the growing tendency towards regionalization in the world oil market. And the absence of universally acceptable quota allocation criteria means that OPEC may have to live with instability for some time to come, but this will be manageable in the short run. In the medium term, however, the call on OPEC oil in the 1990s is predicted to rise to a level commensurate with the sustainable capacities of member states. Producers and consumers have a common interest and should share a similar perspective on the inter-dependence between energy, the environment and economic development. (author).

Depending on scientific and technological progress to prospect for superlarge uranium deposits. Across-century target for uranium resources exploration work in China

International Nuclear Information System (INIS)

Shen Feng

1995-01-01

After over 30 years' development, uranium resources exploration work in China has resulted in the discovery of more than 10 economic types of uranium deposits in 23 provinces (regions) of the whole country and large quantities of uranium reserves have been submitted which guarantee the development of nuclear industry in China. However, characteristics such as smaller size of deposits and ore bodies, and lower ore grade of discovered China's uranium deposits have brought about a series of problems on how to economically exploit and utilize these uranium resources. To prospect for superlarge uranium deposits is a guarantee of making uranium resources essentially meet the demand for the long-term development of nuclear industry in China, and is an important way of improving economic benefits in mining China's uranium resources. It is an important mark for uranium geological exploration work to go up a new step as well. China exhibits the geological environment in which various types of superlarge uranium deposits can be formed. Having the financial support from the state to uranium resources exploration work, having professional uranium exploration teams well-experienced in ore prospecting, having modernized uranium exploration techniques and equipment and also having foreign experience in prospecting for superlarge uranium deposits as reference, it is entirely possible to find out superlarge uranium deposits in China at the end of this century and at the beginning of next century. In order to realize the objective, the most important prerequisite is that research work on metallogenetic geological theory and exploration techniques and prospecting methodology for superlarge uranium deposits must be strengthened, and technical quality of the geological teams must be improved. Within this century, prospect targets should be selected and located accurately to carry out the emphatic breakthrough in exploration strategy

Emerging conservation challenges and prospects in an era of offshore hydrocarbon exploration and exploitation.

Kark, Salit; Brokovich, Eran; Mazor, Tessa; Levin, Noam

Globally, extensive marine areas important for biodiversity conservation and ecosystem functioning are undergoing exploration and extraction of oil and natural gas resources. Such operations are expanding to previously inaccessible deep waters and other frontier regions, while conservation-related legislation and planning is often lacking. Conservation challenges arising from offshore hydrocarbon development are wide-ranging. These challenges include threats to ecosystems and marine species from oil spills, negative impacts on native biodiversity from invasive species colonizing drilling infrastructure, and increased political conflicts that can delay conservation actions. With mounting offshore operations, conservationists need to urgently consider some possible opportunities that could be leveraged for conservation. Leveraging options, as part of multi-billion dollar marine hydrocarbon operations, include the use of facilities and costly equipment of the deep and ultra-deep hydrocarbon industry for deep-sea conservation research and monitoring and establishing new conservation research, practice, and monitoring funds and environmental offsetting schemes. The conservation community, including conservation scientists, should become more involved in the earliest planning and exploration phases and remain involved throughout the operations so as to influence decision making and promote continuous monitoring of biodiversity and ecosystems. A prompt response by conservation professionals to offshore oil and gas developments can mitigate impacts of future decisions and actions of the industry and governments. New environmental decision support tools can be used to explicitly incorporate the impacts of hydrocarbon operations on biodiversity into marine spatial and conservation plans and thus allow for optimum trade-offs among multiple objectives, costs, and risks. © 2015 Society for Conservation Biology.

Oil outlook to 2020

2001-01-01

The OPEC Conference in 2000 developed a price band target of 22-28 US dollars per barrel for the Basket of OPEC crudes, in a bid to stabilise prices. This decision was made in the wake of a 12-month period that had seen tremendous fluctuations, with prices ranging from below 10/b US dollars to above 30/b US dollars. It was expected that the identification of the new price band would play a major role in stabilising oil prices, to the benefit of both producer and consumer. The assessment of potential medium-to-long-term prospects for the oil market, contained herein, are intimately related to these important developments in international oil markets, as well as our understanding of evolving fundamentals. Part 1 of this article, developed using OPEC's World Energy Model (OWEM), describes the reference case. From the demand side, a detailed analysis of both economic growth and intensity movements is used to project the growth of oil demand that can reasonably be expected over the next two decades. A resource-based approach is used to determine feasible longer-term production, utilising the latest data made available last year by the US Geological Survey. The rest of the article deals with various scenarios. The price scenario section considers the impact of high prices, beyond 30/b US dollars, and questions their sustainability. The next section deals with tax scenarios, and shows the extent to which oil demand has been reduced by historical developments in oil product taxation. Finally, a slow growth scenario explores the implications of a pessimistic view of economic growth over the coming years. (author)

Policy Analysis of the Canadian Oil Sands Experience

Energy Technology Data Exchange (ETDEWEB)

None, None

2013-09-01

For those who support U.S. oil sands development, the Canadian oil sands industry is often identified as a model the U.S. might emulate, yielding financial and energy security benefits. For opponents of domestic oil sands development, the Canadian oil sands experience illustrates the risks that opponents of development believe should deter domestic policymakers from incenting U.S. oil sands development. This report does not seek to evaluate the particular underpinnings of either side of this policy argument, but rather attempts to delve into the question of whether the Canadian experience has relevance as a foundational model for U.S. oil sands development. More specifically, this report seeks to assess whether and how the Canadian oil sands experience might be predictive or instructive in the context of fashioning a framework for a U.S. oil sands industry. In evaluating the implications of these underpinnings for a prospective U.S. oil sands industry, this report concentrates on prospective development of the oil sands deposits found in Utah.

World oil and gas resources: status and outlook - A rational attempt at an emotional issue

2008-01-01

This paper examines the status of world oil and gas resources and attempts to provide a rational view of the situation and the prospects available. The author states that only about a quarter of the world's estimated ultimately recoverable oil resources and one eighth of the ultimate gas resources have been produced until today. Further, the author is of the opinion that very significant reserve additions are to be expected not only from the still existing exploration frontiers (e.g. deep water and Arctic fields) but even more so from new hydrocarbon detection tools, advanced recovery technology and from unconventional oil and gas resources. The price situation is discussed as are various developments that not only have a negative but also a positive impact on supplies. Reserves and unconventional resources are discussed, particularly from the pricing point of view. The effect of pricing on consumption is examined, as are new technologies for recovery and the potential available for future exploration

Oil Exploration and Production in Africa since 2014. Evolution of the Key Players and their Strategies

International Nuclear Information System (INIS)

Auge, Benjamin

2018-05-01

The fall in oil prices, which began in fall 2014, had a significant influence on the strategies of the key players in the oil industry in Africa. The continent's oil sector has experienced deep-reaching changes, ranging from a drop in exploration budgets, the disappearance or sale of weakened companies, the reorganization or pullback of the traditional oil majors, the establishment of new companies and the arrival of state-owned companies attracted by the crisis-induced windfall effects. Yet the crisis has not redefined the geography of African production, whose principal giants are and will continue to be Nigeria, Angola, Algeria and Libya, at least in terms of reserves. Nevertheless, new zones have emerged, in particular due to the risks taken by junior players backed by powerful investment funds that have had faith in the potential of geologists and technical teams formerly employed by the big companies. This is first of all the case in East Africa, for oil, in Uganda and Kenya, along with gas, with Tanzania and Mozambique. Several very significant oil and gas discoveries have been made in a new basin located between Mauritania and Guinea, contributing to its development. However, no single African model has taken shape, as each company has followed its own path in making decisions about acquisition and exploration. Whereas traditional players, such as the Western majors ENI and Total, have continued to invest on this continent that plays a central role in their global production and strategy, some big companies, such as ConocoPhilipps, have quite simply left the field, while others, such as BP and ExxonMobil, have made new high-risk acquisitions. As for the large Asian state-owned companies, China's investments in exploration and production have tended to stagnate (concerning CNPC and Sinopec in particular), while others, such as the Indonesian Pertamina or India's ONGC, have significantly bolstered their presence.

Full Text Available Irrigation using produced water, which is generated during crude oil and gas recovery and treated by the exploration industry, could be an option for irrigated agriculture in semiarid regions. To determine the viability of this option, the effects of this treated water on the nutritional status of plants should be assessed. For this purpose, we examined the nutritional changes in sunflowers after they were irrigated with oil - produced water and the effects of this water on plant biomass and seed production. The sunflower cultivar BRS 321 was grown for three crop cycles in areas irrigated with filtered produced water (FPW, reverse osmosis - treated produced water (OPW, or ground water (GW. At the end of each cycle, roots, shoots, and seeds were collected to examine their nutrient concentrations. Produced water irrigation affected nutrient accumulation in the sunflower plants. OPW irrigation promoted the accumulation of Ca, Na, N, P, and Mg. FPW irrigation favored the accumulation of Na in both roots and shoots, and biomass and seed production were negatively affected. The Na in the shoots of plants irrigated with FPW increased throughout the three crop cycles. Under controlled conditions, it is possible to reuse reverse osmosis - treated produced water in agriculture. However, more long - term research is needed to understand its cumulative effects on the chemical and biological properties of the soil and crop production.

Environmental audits of oil and gas properties

Moody, T.D.; Forbes, S.

1991-01-01

The growing concern over one, the cost of correcting environmental damage and two, the potential financial liabilities associated with the acquisition, sale or lease of oil and gas properties, has led many prospective buyers to investigate the environmental liabilities associated with the property transfer. The environmental audit provides a tool or mechanism to assist the prudent investor in identifying environmental problems that could adversely effect an otherwise normal business activity. Accordingly, an environmental audit can identify potential environmental liabilities associated with the property, thus allowing the investor an opportunity to better assess financial risks. In addition, should the negative findings of the environmental audit be limited, the findings could be used by the buyer in negotiating the final price of the subject property to account for potential or known liabilities. As this suggests, environmental damage to an oil and gas property does not necessarily render the property worthless. This paper provides a brief guide on environmental audits of oil and gas properties as well as general information on the most common exploration and production wastes

A host of large uranium deposits have been successively discovered abroad by means of geological exploration, metallogenetic model studies and the application of new geophysical and geochemical methods since 1970's. Thorough undertaking geological research relevant to prospecting for super large uranium deposits have attracted great attention of the worldwide geological circle. The important task for the vast numbers of uranium geological workers is to make an afford to discover more numerous large and super large uranium deposits in China. The author comprehensively analyses the regional geological setting and geological metallogenetic conditions for the super large uranium deposits in the world. Comparative studies have been undertaken and the prospecting direction and favourable target areas for the exploration of super large uranium deposits in China have been proposed

1992-01-01

This paper examines the feasibility, relative to the specific capabilities of the Italian agricultural industry, of the production of biomass fuels and lubricating oils. A comparative cost benefit analysis is made to determine the technical and economic convenience of the production of grain or vegetable oil derived biomass for direct use as lubricants, fuel oils or for conversion into ethanol fuels. The suitability of different types of engines is examined for the direct combustion of vegetable oils and for the combustion of ethanol fuels. The study also has a look at what should be the suitable mix of Italian Government agricultural, environmental and fiscal strategies to support and encourage the production and use of industrial vegetable fuel oils and lubricants

Resources and future supply of oil

International Nuclear Information System (INIS)

Kjaerstad, Jan; Johnsson, Filip

2009-01-01

This paper examines global oil resources and the future global oil supply/demand balance. The paper builds upon several comprehensive databases designed during the work and considerable efforts have been made to review what must be considered the most reliable data. Global oil resources have been investigated on three levels; country, company and field levels. Although no decisive conclusions or quantitative assessments can be made with respect to the global oil resource base, remaining resources appear to be sufficient to meet demand up to 2030 as projected in the 2006 (and 2007) world energy outlook by the IEA. Significant resources have already been discovered beyond proven reserves, many prospective regions remain to be fully explored and there are vast volumes of recoverable unconventional oil. However, it is also concluded that global supply of oil probably will continue to be tight, both in the medium term as well as in the long term mainly as a consequence of above-ground factors such as investment constraints, geopolitical tensions, limited access to reserves and mature super-giant fields. Production of unconventional oil and synthetic fuels is not believed to significantly alter this situation. Although an increasing number of recent reports have indicated an imminent or 'soon to come' peak in global oil supply, it has not been found that any of these reports have contributed with any new information on oil resources or oil supply ability. Nevertheless, there is a distinct possibility that global oil production may peak or plateau in a relatively near future, not caused by limited resources but because too many factors over long time constrain investments into exploration and production. The lack of transparency within the oil industry obviously prevents any accurate analysis of future production and supply ability. Moreover, our ability to analyse the sector will become more difficult in the future as oil increasingly will have to be sourced from

Innovative Approaches to the Solution of Searching Hydrocarbons in Deep Horizons of the Volga-Ural Oil and Gas Province

2017-03-01

Full Text Available The article draws attention to the problem of hydrocarbon exploration in deep horizons, which is especially important for the old oil and gas bearing provinces, in particular, for the Volga-Ural province. The example of Riphean-Vendian deposits shows that the solution of this problem is possible if we use not only data of the structural plans of the studied horizons, but also the presence in the immediate vicinity of the identified structures of the oil feeding channels (faults allocated by the high-depth CDP seismic survey. Based on a comparative analysis of the structure of the White Tiger field (Vietnam and Zhigulev arch, it was concluded that they are very similar and that it is expedient to set up, within the last tectonic element, purposeful studies to explore the prospects of oil and gas potential of the Precambrian basement.

Alaska's coastal plain can sustain both wilderness values and oil production, says Jeslie Kaleak, Sr., former mayor of North Slope Borough in Borrow, Alaska. Kaleak is director is Barrow Operations for North Slope Regional Corporation. Nevertheless, Kaleak contends, [open quotes]the people in the Lower 48 want to keep us from developing this land because of some preconceived notion of the land as a wilderness paradise.[close quotes] Kaleak insists that the Inupiaq people, American Indians inhabiting the Northern Slope region, have provided for their families for thousands of years by turning to the natural environment. Their decision to support oil development is no different. Kaleak contends that the mineral and oil wealth of the North Slope has allowed the Inupiaq people to improve their standard of living drastically. Oil development on the coastal plain, Kaleak contends, could provide similar economic benefits. [open quotes]We cannot define our lives by the vision of distant people who view the North Slope as one great outdoor Disneyland where...all resources remain off limits to us,[close quotes] Kaleak concludes.

Exploring the Impact of Commuter’s Residential Location Choice on the Design of a Rail Transit Line Based on Prospect Theory

Directory of Open Access Journals (Sweden)

Ding Liu

2014-01-01

Full Text Available This paper explores the impact of prospect theory based commuter’s residential location choice on the design problem of a rail transit line located in a monocentric city. A closed-form social welfare maximization model is proposed, with special consideration given to prospect theory based commuter’s residential location choice over years. Commuters are assumed to make residential location choice by a trade-off between daily housing rent and generalized travel cost to minimize their prospect values. The solutions properties of the proposed model are explored and compared analytically. It is found that overestimation exists for the optimal solutions of rail line length, headway, and fare based on traditional utility theory, compared with the optimal solutions of the proposed prospect theory based model. A numerical example is given to illustrate the properties of the proposed model.

Mauborgne, Marie-Laure; Allioli, Françoise; Manclossi, Mauro; Nicoletti, Luisa; Stoller, Chris; Evans, Mike

2017-09-01

When designing nuclear tools for oil exploration, one of the first steps is typically nuclear modeling for concept evaluation and initial characterization. Having an accurate model, including the availability of accurate cross sections, is essential to reduce or avoid time consuming and costly design iterations. During tool response characterization, modeling is benchmarked with experimental data and then used to complement and to expand the database to make it more detailed and inclusive of more measurement environments which are difficult or impossible to reproduce in the laboratory. We present comparisons of our modeling results obtained using the ENDF/B-VI and ENDF/B-VII cross section data bases, focusing on the response to a few elements found in the tool, borehole and subsurface formation. For neutron-induced inelastic and capture gamma ray spectroscopy, major obstacles may be caused by missing or inaccurate cross sections for essential materials. We show examples of the benchmarking of modeling results against experimental data obtained during tool characterization and discuss observed discrepancies.

Numerous irregular flow structures exist in the complicated multiphase flow and result in lots of disparate spatial dynamical flow behaviors. The vertical oil-water slug flow continually attracts plenty of research interests on account of its significant importance. Based on the spatial transient flow information acquired through our designed double-layer distributed-sector conductance sensor, we construct multilayer modality-based network to encode the intricate spatial flow behavior. Particularly, we calculate the PageRank versatility and multilayer weighted clustering coefficient to quantitatively explore the inferred multilayer modality-based networks. Our analysis allows characterizing the complicated evolution of oil-water slug flow, from the opening formation of oil slugs, to the succedent inter-collision and coalescence among oil slugs, and then to the dispersed oil bubbles. These properties render our developed method particularly powerful for mining the essential flow features from the multilayer sensor measurements.

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.

Increased oil recovery: secondary and tertiary. Application and future prospect

Energy Technology Data Exchange (ETDEWEB)

Whiting, R L

1978-01-01

Oil is initially produced using the nature reservoir pressure present, in a process called primary oil recovery. Secondary recovery uses artificial means to increase the natural reservoir pressure; tertiary, or enhanced oil recovery, uses a number of methods to enhance the flow characteristics of the oil. The scope for such techniques to increase the yield from oil fields in the US is estimated; the practicality of their application is shown to be particularly dependent upon pricing, taxation, and other existing policies. 16 references.

Caldwell, R.L.; Mills, W.R. Jr.; Orr, W.L.; Allen, L.S.

1977-01-01

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)

Manitoba oil activity review, 1991

International Nuclear Information System (INIS)

1992-04-01

In an annual survey of Manitoba's petroleum industry, data are presented on oil and natural gas leases and sales, geophysical activity, exploration and drilling activity, production, exports to other provinces and the USA, oil prices and sales value, royalties and taxes, direct revenues from oil exploration and development, reserves, industry expenditures, and oil fields. Throughout the report, explainations are given of the items covered. Descriptions are made of new developments, the oil market, oil policies, incentive programs, and industrial activities. During 1991, 54 wells were drilled, compared to 79 in 1990. Oil production was down ca 3% from 1990 levels, to 712,792 m 3 , the value of the oil produced decreased 21% to ca $90.3 million, and provincial revenues from the oil industry declined by 15%. Oil industry expenditures in the province were estimated at $69 million, down 9% from 1990. As of the end of 1991, there were 11 oil fields and 118 non-confidential oil pools designated in Manitoba. The forecast for 1992 indicates that exploration activity will increase in response to new incentive programs. Crude oil production is expected to decline slightly to about 667,000 m 3 . 9 figs., 17 tabs

Breakthrough and prospect of shale gas exploration and development in China

2016-01-01

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

Will the 21. century be the petroleum challenge century? The petroleum problem is no longer the affair of experts and journalists, it challenges also governments and consumers in pressing terms. If there is today a petroleum problem, there is no oil or gas shortage for the moment. The cumulated oil and gas reserves would allow to face the demand of the century, with the condition that investments in exploration, field development, production, and back-end of oil and gas industries will be done in time. This book, written by specialists of energy economics and geopolitics shows up some of the key questions of our energy future. In particular, it invites us to never forget the basic heavy trends of the hydrocarbons sector in order to never be trapped by superficial extrapolations of short term phenomena. Content: heavy trend of oil prices at the 2020 prospects, natural gas take over?; oil and gas geopolitics: enough of hydrocarbons for the 21. century; Russia and Caspian sea oil and gas weight; China: a new strategic actor of the energy scene; influence of 'futures' market, of speculation, and of stocks on hydrocarbon prices; which future for LNG?; natural gas in the USA: towards a new foreign dependence.

In the next future, Indonesia will face oil scarcity. The present reserves are estimated to be depleted in 20 years. However, after primary and secondary recovery processes, there are still more than 50% of original oil in place remaining in the reservoir, and this could be recovered by using tertiary recovery method or which is known as enhanced oil recovery (EOR) processes. Among the three major methods of EOR, steam flooding is a thermal recovery method into which High Temperature Reactor (HTR) module can be integrated for producing steam. However, the feasibility of application of HTR as an alternative to conventional oil-fired steam generator will depend strongly on the price of oil. This paper discusses EOR screening for Indonesian oil fields to identify the appropriate oil reservoirs for steam flooding application as well as the possibility of steam supply by HTR module. Also reviewed is the previous study on HTR application for Duri Steam Flood Project. (author). 8 refs, 6 figs, 5 tabs

In this paper, the paleo-interlayer-oxidation type sandstone-hosted uranium deposits occurred in the Meso-Cenozoic continental basins in China are divided into 3 subtype, they are stratum over lapping buried subtype, structure-uplifting destroy subtype and faulted-folding conserved subtype. The metallogenic characteristics, metallogenic model and exploration prospect for these 3 subtypes uranium deposits are discussed. It is proposed that the paleo-interlayer-oxidation type sandstone-hosted uranium deposits, besides the recent interlayer oxidation type sandstone-hosted uranium deposits, are of great prospecting potential in the Meso-Cenozoic continental basins in China. Therefore, the metallogenic theory of these types uranium deposits should be conscientiously summarized and replenished continuously so as to propel forward the exploration of the sandstone-hosted uranium deposits in China.

Full Text Available Prospects for the growth of hydrocarbon (HC reserves in the Timan-Pechora basin are associated with poorly explored areas, which include the Korotaikha Depression, which is a very difficult region for oil and gas exploration. Analysis and reinterpretation of both old and new seismic data made it possible to identify a number of anticlinal structures within the region, as well as to identify possible lithological HC traps, such as reefing bodies of late Devonian-Early Carboniferous age and delta sand formations of the Permian-Triassic age. The wide stratigraphic range of the sedimentary cover makes it possible to select several hydrocarbon systems in the basin of the Korotaikha Depression. Basin modeling has shown that there are all conditions for НС generation and accumulation in the Korotaikha Basin. Based on the results of the simulation, Korotaikha Basin should be considered as a potentially promising oil and gas area, where the main oil and gas accumulations are located in the side parts of the basin, and also within the inversion highs and saddles. The total booked geological resources of hydrocarbons may amount to about 1.7 billion tons standard fuel. Korotaikha Depression and its aquatorial continuation can be referred to the category of major oil-gas search regions.

Highlights: • Jojoba oil is a unique oil formed by long esters instead of triglycerides. • Jojoba cake is gaining interest because of the extraction of valuable chemicals. • Jojoba oil heterogeneous-catalyzed methanolysis makes the process more profitable. - Abstract: Jojoba oil, which is derived from the extraction of Jojoba seed, has a peculiar molecular structure in comparison with the rest of conventional oils. Jojoba oil is formed by long monounsaturated esters whereas the rest of the oils are usually composed by triglycerides. This unconventional structure confers to Jojoba oil unique properties and characteristics that are very valuable for fine chemical industry and for the production of pharmaceuticals. In addition, Jojoba oil can be an excellent source of fatty acid alkyl esters or biodiesel after the transesterification process and the purification steps. This review presents general information about the production of Jojoba oil and its derivatives, its composition, oil extraction process and the applications of this oil when it is used directly or after chemical transformation as well as the possible purposes of Jojoba meal after extraction. In addition, this paper contemplates the advantages and disadvantages of the use of homogeneous and heterogeneous catalysts for the Jojoba oil transesterification as well as different methods to obtain long monounsaturated alcohols, which have pharmaceutical applications, after being separated from biodiesel. The properties of the products derived from the transesterification of Jojoba oil are broadly discussed. Moreover, this review suggests future research opportunities such as a possible biorefinery using Jojoba oil as main raw material, supercritical methods and simultaneous extraction/reaction process which are fully discussed.

International exploration by independent

Recent industry trends indicate that the smaller U.S. independents are looking at foreign exploration opportunities as one of the alternatives for growth in the new age of exploration. Foreign finding costs per barrel usually are accepted to be substantially lower than domestic costs because of the large reserve potential of international plays. To get involved in overseas exploration, however, requires the explorationist to adapt to different cultural, financial, legal, operational, and political conditions. Generally, foreign exploration proceeds at a slower pace than domestic exploration because concessions are granted by a country's government, or are explored in partnership with a national oil company. First, the explorationist must prepare a mid- to long-term strategy, tailored to the goals and the financial capabilities of the company; next, is an ongoing evaluation of quality prospects in various sedimentary basins, and careful planning and conduct of the operations. To successfully explore overseas also requires the presence of a minimum number of explorationists and engineers thoroughly familiar with the various exploratory and operational aspects of foreign work. Ideally, these team members will have had a considerable amount of on-site experience in various countries and climates. Independents best suited for foreign expansion are those who have been financially successful in domestic exploration. When properly approached, foreign exploration is well within the reach of smaller U.S. independents, and presents essentially no greater risk than domestic exploration; however, the reward can be much larger and can catapult the company into the 'big leagues.'

Full Text Available The aim. The aim is to develop the energy efficient technologies to explore hydro geothermal resources of different energy potential.Methods. Evaluation of the effectiveness of the proposed technologies has been carried out with the use of physical and mathematical, thermodynamic and optimization methods of calculation and the physical and chemical experimental research.Results. We propose the technology of integrated exploration of low-grade geothermal resources with the application of heat and water resource potential on various purposes. We also argue for the possibility of effective exploration of geothermal resources by building a binary geothermal power plant using idle oil and gas wells. We prove the prospect of geothermal steam and gas technologies enabling highly efficient use of thermal water of low energy potential (80 - 100 ° C degrees to generate electricity; the prospects of complex processing of high-temperature geothermal brine of Tarumovsky field. Thermal energy is utilized in a binary geothermal power plant in the supercritical Rankine cycle operating with a low-boiling agent. The low temperature spent brine from the geothermal power plant with is supplied to the chemical plant, where the main chemical components are extracted - lithium carbonate, magnesium burning, calcium carbonate and sodium chloride. Next, the waste water is used for various water management objectives. Electricity generated in the binary geothermal power plant is used for the extraction of chemical components.Conclusions. Implementation of the proposed technologies will facilitate the most efficient development of hydro geothermal resources of the North Caucasus region. Integrated exploration of the Tarumovsky field resources will fully meet Russian demand for lithium carbonate and sodium chloride.

The oil and gas equipment and services market in Nigeria

International Nuclear Information System (INIS)

2003-01-01

The oil and gas market in Nigeria is being expanded by the Nigerian government over the 2003-2010 period through increased exploration and production (E and P) in new areas. Other measures being implemented are the improvements of structural flaws that hamper industry growth, the modernization of the weak downstream sector, and attempts to attract foreign investment and technologies required for petroleum development. In 2001, it was estimated that the market for oil and gas equipment in Nigeria was approximately 1.03 billion dollars, and is expected to reach 1.15 billion dollars in 2002. In deep-sea areas, major offshore E and P projects are being planned by large oil multinationals. The implementation of several gas-related E and P operations and major liquefied natural gas (LNG) and gas-to-liquid (GTL) projects are being supported by the government of Nigeria to develop the natural gas sector. Onshore and offshore exploration, surveying and geophysical prospecting, drilling equipment, facilities maintenance, deepwater E and P, equipment for LNG/GTL facilities, enhanced recovery equipment and services, gas re-injection technology, pipelines, and the refinery sector are all areas where Canadian equipment and service suppliers could benefit from opportunities in Nigeria. One of the most prominent foreign player in the Nigerian market is Royal Dutch Shell. As far as the offshore deepwater E and P sub-sector, the three major players are Shell, ChevronTexaco, and ExxonMobil. The Nigerian government advocate in upstream and downstream oil industries in the country is Nigeria National Petroleum Corporation (NNPC). The primary domestic end-users of oil and gas equipment and services are member companies of the Nigerian Association of Indigenous Petroleum Exploration Companies (NAIPEC). Canadian companies are encouraged to form joint venture partnerships in oil and gas projects, as foreign majors operating in Nigeria tend to rely on the skills and expertise of foreign

The economics of petroleum exploration and development west of Scotland

International Nuclear Information System (INIS)

Kemp, A.G.; Stephen, L.

2001-01-01

This paper examines the economics of oil and gas exploration and development in the West of Scotland region. A considerable exploration effort has resulted in some discoveries but the overall success rate has been quite low. The region is comprised of several distinct geological basins. To date the Judd Basin has experienced the best discovery rate. Expected returns as measured by expected monetary values are generally low, confirming the high-risk nature of the region. The most economical field development concept depends to a large extent on a combination of field size and water depth which vary markedly from basin to basin. In typical cost conditions at an $18 price returns to investors in medium and large-sized fields at the development phase are positive, but at $14 only when costs are relatively low are positive returns in prospect. Stand-alone gas developments are very unlikely to be viable in current market conditions. The fuller exploitation of the whole region requires higher oil and gas prices and /or significant innovation and technological progress. (Author)

Essential abilities of the oil-finding geologist

International Nuclear Information System (INIS)

Sebring, L. Jr.

1992-01-01

This paper reports that the oil-finder must be able to locate and recognize a significant anomaly, and he must be able to get this anomaly tested. A significant anomaly is defined as a trapping anomaly, one that might trap hydrocarbons. So, the oil-finder has a dual job. He must be both a scientist and a salesman, a prospector and a promoter, a researcher and a hustler. He must locate the prospect, and, unless he is financially self-sufficient, he must persuade his management or his investors to test the prospect. One ability is not enough. To be a successful oil-finder he must have both abilities, although not necessarily in equal degree. The truth is self-evident-all geologist are not equal in ability; either as trap locators or as prospect salesmen. Some have considerable ability to locators or a s prospect salesmen. Some have considerable ability to locate anomalies, but have great difficulty in persuading their management or investors to test their prospects. Other have difficulty in recognizing a prospect, but once one is located can easily persuade their management or clients to test it. And some, a truly blessed minority, can not only easily locate the recognize a significant anomaly but can, just as easily, persuade their management or investors to pursue the investigation of this anomaly to its logical conclusion

Retrospect and prospects of edible oil and bio-diesel in Pakistan - a review

Zaman, S.B.; Majeed, S.; Ahmad, S.

2010-01-01

Globally resources of petro-fuels are diminishing at a rapid rate. Efforts are underway to develop sources of bio-fuels. Out of the known sources of bio-fuels, Jatropha is one of the most promising option. The purpose of this study was to evaluate primarily the regional and global experiences to assess the potential of Jatropha farming in Pakistan and to conduct a comparative economic analysis of alternate feasible options e.g. production of oilseeds, which are also being imported in large quantities. Temporal analysis (1950-09) for edible oil consumption, production and imports is made. Projections for edible oil are worked out up to 2030. As there have been large variations in yield of Jatropha reported by various studies conducted in India and other countries, therefore most reliable data have been selected for analysis to assess the prospects in Pakistan. Comparative economic analysis is made in terms of oil contents, number of crops per year, yield and gross returns of oilseed crops and Jatropha. Analysis shows that increase in production of edible oil over the time is negligible against the large increase in requirement resulted in higher production gap being filled through imports. Projections made for edible oils illustrated that production gap is going to be wider, which is currently 1.86 million tonnes (mt) and projected to be 3.4 mt by 2030. Jatropha seed production analysis of water-yield functions revealed that yield varies from 1.1 t ha/sup -1/ in drought or dry spells to 12.75 t ha/sup -1/ with full irrigation in favorable environments. Benefit-cost analysis shows that break-even point can be achieved in fourth year of plantation of Jatropha. The projected consumption in Pakistan for petro-fuel for 2025 is 35.1 mt, which is almost double of the current consumption. Thus, the target projections for replacement of petro-fuel with bio-diesel will be 3.51 mt for which 3.5 mha of land is required, as Jatropha has to be grown in marginal areas with

Designing tools for oil exploration using nuclear modeling

Full Text Available When designing nuclear tools for oil exploration, one of the first steps is typically nuclear modeling for concept evaluation and initial characterization. Having an accurate model, including the availability of accurate cross sections, is essential to reduce or avoid time consuming and costly design iterations. During tool response characterization, modeling is benchmarked with experimental data and then used to complement and to expand the database to make it more detailed and inclusive of more measurement environments which are difficult or impossible to reproduce in the laboratory. We present comparisons of our modeling results obtained using the ENDF/B-VI and ENDF/B-VII cross section data bases, focusing on the response to a few elements found in the tool, borehole and subsurface formation. For neutron-induced inelastic and capture gamma ray spectroscopy, major obstacles may be caused by missing or inaccurate cross sections for essential materials. We show examples of the benchmarking of modeling results against experimental data obtained during tool characterization and discuss observed discrepancies.

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.

Regional resource depletion and industry activity: The case of oil and gas in the Gulf of Mexico

Science.gov (United States)

Attanasi, E.D.

1986-01-01

Stable and declining oil and gas prices have changed the industry's price expectations and, along with depletion of promising exploration prospects, has resulted in reduced exploration. Even with intensive additional exploration, production in most U.S. areas is expected to decline. What does this imply for the drilling and petroleum industry suppliers in particular regions? How should planners in government and the private sector project and incorporate the consequences of these changes in their strategies? This paper answers these questions for the industry operating in the offshore Gulf of Mexico. Future oil and gas production, as well as demand for offshore drilling and production facilities, are shown to depend on the size distribution of undiscovered fields, their associated production costs, and oil and gas prices. Declining well productivity is a consequence of development of progressively smaller fields so that long-run drilling demand should not decline in proportion to the expected production decline. Calculations show a substantial payoff to the drilling industry, in terms of potential demand increases, if it can develop and implement cost reducing technologies. Implications of these results for other offshore producing areas such as the North Sea are also discussed. ?? 1986.

Niu, Mengting; Wang, Sha; Han, Xiangxin; Jiang, Xiumin

2013-01-01

Highlights: • The whole formation process of shale oil might be divided into four stages. • Higher ash/shale mass ratio intensified the cracking and coking of shale oil. • Ash/shale ratio of 1:2 was recommended for oil shale fluidized bed retort with fine oil-shale ash as solid heat carrier. - Abstract: For exploring and optimizing the oil shale fluidized bed retort with fine oil-shale ash as a solid heat carrier, retorting experiments of oil shale and fine oil-shale ash mixtures were conducted in a lab-scale retorting reactor to investigate the effects of fine oil-shale ash on shale oil. Oil shale samples were obtained from Dachengzi Mine, China, and mixed with fine oil-shale ash in the ash/shale mass ratios of 0:1, 1:4, 1:2, 1:1, 2:1 and 4:1. The experimental retorting temperature was enhanced from room temperature to 520 °C and the average heating rate was 12 °C min −1 . It was found that, with the increase of the oil-shale ash fraction, the shale oil yield first increased and then decreased obviously, whereas the gas yield appeared conversely. Shale oil was analyzed for the elemental analysis, presenting its atomic H/C ratio of 1.78–1.87. Further, extraction and simulated distillation of shale oil were also conducted to explore the quality of shale oil. As a result, the ash/shale mixing mass ratio of 1:2 was recommended only for the consideration of increasing the yield and quality of shale oil

Exploring the core factors and its dynamic effects on oil price: An application on path analysis and BVAR-TVP model

Chai Jian; Guo, Ju-E.; Meng Lei; Wang Shouyang

2011-01-01

As the uncertainty of oil price increases, impacts of the influential factors on oil price vary over time. It is of great importance to explore the core factors and its time-varying influence on oil price. In view of this, based on the PATH-ANALYSIS model, this paper obtains the core factors, builds an oil price system VAR model, which uses demand, supply, price, and inventory as endogenous variables, and China's net imports as well as dollar index as exogenous variables. Then we set up a BVAR-TVP (Time varying parameter) model to analyze dynamic impacts of core factors on oil price. The results show that: (1) oil prices became more sensitive to oil supply changes, and the influence delays became shorter; (2) the impact of oil inventories on oil prices with a time lag of two quarters but has a downward trend; (3) the impact of oil consumption on oil prices with a time lag of two quarters, and this effect is increasingly greater; (4) the US dollar index is always the important factor of oil price and its control power increases gradually, and the financial crisis (occurred in 2008) further strengthens the influence of US dollar. - Highlights: ► We build an oil price VAR model based on the PATH-ANALYSIS results. ► The dynamic effects of core factors on oil price was studied by BVAR-TVP model. ► Oil prices became more sensitive to oil supply changes. ► The effect of oil consumption on oil prices is increasingly greater. ► Financial crisis further strengthens the influence of US dollar on oil price.

Exploring the undulating plateau: the future of global oil supply.

Science.gov (United States)

Jackson, Peter M; Smith, Leta K

2014-01-13

In this paper, we analyse the factors that will influence long-term oil supply and describe the future form of the global oil supply profile as an 'undulating plateau' rather than an irreversible, short-term peak or an ever upward trend of increasing production. The ultimate transition from a world of relatively plentiful and cheap oil to one of tight supply and high cost will be slow and challenging. An understanding of the signposts for the future path of supply and the drivers of that profile will be critical to managing the transition. The ultimate form of the global supply curve may well be dictated by demand evolution rather than a limited resource endowment in the longer term. Several factors will probably control future global oil supply. We believe that the scale of global oil resource will not constitute a physical supply limit for at least the next two or three decades. However, all categories of oil resources are already more expensive to develop than in the past, requiring high oil prices to stimulate supply growth. Lower rates of oil demand growth relative to economic growth, combined with more challenging supply growth, will probably lead to an undulating plateau sometime after 2040, with demand from non-Organization for Economic Cooperation and Development states continuing to dominate. Upstream investment requirements and oil price volatility will increase towards and beyond the undulating production plateau. In this new world, high oil prices will induce demand destruction, fuel substitution and ever increasing energy efficiency. As we discuss below, the fundamental differences between the IHS Cambridge Energy Research Associates' (IHS CERA) view of the future of oil supply and many peak oil supply models are the timing of the onset of a dramatic slowdown in the rate of growth of supply and the existence or otherwise of a production plateau. We do not dispute that supply will plateau and eventually fall; the question is when, how and at what price

Investment in Exploration-Production and Refining - 2017

Maisonnier, Guy; Hureau, Geoffroy; Serbutoviez, Sylvain; Silva, Constancio

Based on surveys of expert opinion, in the absence of extraordinary geopolitical or economic circumstances, oil prices could rise in the range of $55 to $70/barrel, compared with $54/barrel in 2017. This prospect for higher prices is consistent with the expected re-stabilization of the market and a favorable economic and financial climate. Shifts in oil prices are clearly possible, upward in the case of potentially weak investment in exploration/production, or downward if U.S. supply is greater than previously expected. The wholesale price of natural gas, which rose during 2017 in Europe, Japan and the United States, may again rise in 2018 due to steady demand and changes in the price of oil and coal. Following two years of significant declines (-24% in 2015, -28% in 2016) worldwide investment in exploration-production (E and P) grew 4% in 2017 to reach $390 billion ($billion). Growth is focused in North America, where investment jumped by more than 30%, while it fell slightly in the rest of the world, especially in Europe. This can be attributed to independent oil companies, whose worldwide investment rose 23%, while the E and P budget for NOCs was stagnant and those for the major oil companies continued to sharply decline (-16%). Except for the U.S. onshore shale drilling market, all Exploration and Production markets have continued to decline since 2015 with the drop in oil prices. The markets lost half their value over a three year period. Offshore drilling, when carried out in deep and ultra-deep water, continues to decline due to excessively high intrinsic costs. Only those projects that have considerably revised their costs (-30 to -40%) could be approved.

International exploration by independents

International Nuclear Information System (INIS)

Bertagne, R.G.

1991-01-01

Recent industry trends indicate that the smaller US independents are looking at foreign exploration opportunities as one of the alternatives for growth in the new age of exploration. It is usually accepted that foreign finding costs per barrel are substantially lower than domestic because of the large reserve potential of international plays. To get involved overseas requires, however, an adaptation to different cultural, financial, legal, operational, and political conditions. Generally foreign exploration proceeds at a slower pace than domestic because concessions are granted by the government, or are explored in partnership with the national oil company. First, a mid- to long-term strategy, tailored to the goals and the financial capabilities of the company, must be prepared; it must be followed by an ongoing evaluation of quality prospects in various sedimentary basins, and a careful planning and conduct of the operations. To successfully explore overseas also requires the presence on the team of a minimum number of explorationists and engineers thoroughly familiar with the various exploratory and operational aspects of foreign work, having had a considerable amount of onsite experience in various geographical and climatic environments. Independents that are best suited for foreign expansion are those that have been financially successful domestically, and have a good discovery track record. When properly approached foreign exploration is well within the reach of smaller US independents and presents essentially no greater risk than domestic exploration; the reward, however, can be much larger and can catapult the company into the big leagues

Shape memory alloy actuated accumulator for ultra-deepwater oil and gas exploration

Science.gov (United States)

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.

Aliphatic-aromatic hydrocarbons and heavy metals (Cd, Cu, Co, Cr, Ni, Pb and Zn) were estimated in soil and leaf samples of Machilus bombycina (host plant of Antheraea assama silkworm) plantation along with atmospheric benzene, toluene and xylene (BTX) concentration near the oil exploration region of upper Assam, India, during the pre-monsoon and post-monsoon periods in six different sites. The results revealed higher aliphatic-aromatic hydrocarbons (ranging from 26.55 to 59.42 mg kg -1 ) and heavy metal contaminations in all the six soil sampling sites during the pre-monsoon period while the trend was the opposite for the plant leaves. Polyaromatic hydrocarbons (9.85 mg kg -1 ) were found in one soil sampling site near an abandoned oil well. The lead concentration in the soil showed values from 14.36 ± 1.5 to 96.5 ± 5.6 mg kg -1 and found to be higher than the WHO limit in most of the samples. The aliphatic-aromatic hydrocarbon m-xylene was also found in M. bombycina plant leaves which could be traced due to crude oil. Cd and Pb concentrations in leave samples were found to be higher than the maximum allowable limit of 0.3 and 5.3 mg kg -1 , respectively. Principal component analysis of hydrocarbons in soil and leaves showed different clusters during the pre-monsoon and post-monsoon periods. The crude protein and total carbohydrate contents in the leaves were lower than those of uncontaminated samples which are an indication of a major disturbance to overall growth of plants. BTX concentration was found in the range of 119-198 μg m -3 which indicates that atmospheric contamination in the studied area is causing the death of A. assama larvae.

The Gulf of St Lawrence is under immediate pressure for oil and gas exploration, particularly at the Old Harry prospect. A synthesis of the regulatory process that has taken place over the last few years indicates that important societal decisions soon to be made by various ministries and environmental groups are going to be based on numerous disagreements between the private sector and government agencies. The review also shows that the regulatory process has taken place with a complete lack of independent oceanographic research. Yet, the Gulf of St Lawrence is a complex environment that has never been specifically studied for oil and gas exploitation. Motivated by this knowledge gap, preliminary numerical experiments are carried out where the spreading of a passive floating tracer released at Old Harry is examined. Results indicate that the tracer released at Old Harry may follow preferentially two main paths. The first path is northward along the French Shore of Newfoundland, and the second path is along the main axis of the Laurentian Channel. The most probable coastlines to be touched by water flowing through Old Harry are Cape Breton and the southern portion of the French Shore, especially Cape Anguille and the Port au Port Peninsula. The Magdalen Islands are less susceptible to being affected than those regions but the probability is not negligible. These preliminary results provide guidance for future more in-depth and complete multidisciplinary studies from which informed decision-making scenarios could eventually be made regarding the exploration and development of oil and gas at the Old Harry prospect in particular and, more generally, in the Gulf of St Lawrence

Oil and gas markets, companies, and technology in the 1990`s and beyond

Energy Technology Data Exchange (ETDEWEB)

Kennedy, J.L.

1995-08-01

During the late 1990`s and beyond, oil prices will be stagnant while costs increase, competition for markets and capital will be fierce, funds available for exploration and development will be limited, and environmental extremists will keep prospective areas off-limits. Higher taxes will limit growth in oil and gas demand and reapportion energy market shares. And a campaign to brand oil use as an ``addiction`` that must be cured will gather steam. But opportunities abound, too, even in the US High-quality properties are available throughout the US, independents can find and develop reserves cheaper than the majors, and new tools are available to reduce risks both in the field and in the market. Gas prices are firming and natural gas is often labeled the ``fuel of the future.`` To succeed in the petroleum industry of the 1990`s, all companies must accept change, be creative, and take initiative. To prosper, oil and gas producers and refiners and those who supply and serve the industry must face the new realities of the market. They cannot mark time until the return of 4,000 active rigs and $40/bbl oil. those days are never coming back. Never.

This work has as purpose to discuss the ethical aspects of the petroleum exploration mainly that ones which are referred to the intergenerational question. In this context, it is intended to discourse on the payment of royalties in reason of the exploration of oil, as a tool that guarantees the intergenerational fairness. Conceptually, the goal of the payment of royalties for the exploration of an exhaustible is exactly to guarantee that the future generations are compensated by the absence of the explored natural resources. Moreover, the work intends to verify whether the current Brazilian model of distribution and application of the referring resources that derives of the oil production corroborates for the sustainability of the future generations, which will not be able to count on the cited finite natural resources.

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

International Nuclear Information System (INIS)

Landon, L.; Pannozzo, L.

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

Deepwater Gulf of Mexico: high prospects

International Nuclear Information System (INIS)

Kirkland, G.

2000-01-01

The present and future role of the deepwater Gulf of Mexico to meeting natural gas requirements of the United States are reviewed.The steady increase in U.S. demand, outpacing U.S.supply for over 10 years and the increasing reliance by the USA on Canadian exports is demonstrated in conjunction with the '30 Tcf Challenge'. Regarding the Gulf of Mexico specifically, it is estimated that to meet expectations, production there needs to grow to 22 Bcfpd by 2020, especially the deepwater pools which have a potential of 80 to 140 Tcf over the next 50 years. These pools already produce as much oil as the shelf region, but only 25 per cent as much gas. To produce the expected 7 to 12 Bcfpd oil production must reach 4 million barrel of oil per day, which involves cycle time, new technologies and cost challenges. Much of the new technology needed is related to cutting costs and while good progress is being made, it is argued that further gains could occur if international technology were applied in the Gulf. The rate of success in exploration has also improved, with over one billion barrels of deepwater discoveries per year over the last four years. Cycle times have also improved, although the impact of cycle time in the deeper water regions is cause for some concern. The overall assessment is that to get the gas, one has to get the oil first, meaning that deepwater success is more dependent on oil prices than on gas prices. Nevertheless, the need for developing and applying new technologies remains paramount, including the application of existing foreign technologies that have proven successful elsewhere. It is equally important to demonstrate a high level of environmental stewardship, and to continue focusing on cycle time, including access to prospective acreage, a well-trained workforce, and reasonable regulatory and permitting requirements

This paper starts from the assumption that, for various reasons, the supply of OPEC oil required to meet a rising world energy demand will continue to be limited. Its purpose is to present a synoptic look at the various sources of energy which are alternatives to OPEC oil, with an economic commentary on the prospects for each source. A wide variety of projects are going forward for the development of non-OPEC oil, gas, coal, and nuclear power, as well as renewable energy resources. Special attention is devoted to questions of energy pricing, investment costs, and sources of finance. (author)

Multiple sets of organic-rich shales developed in the Upper Paleozoic of the northwestern Guizhong Depression in South China. However, the exploration of these shales is presently at a relatively immature stage. The Upper Paleozoic shales in the northwestern Guizhong Depression, including the Middle Devonian Luofu shale, the Nabiao shale, and the Lower Carboniferous Yanguan shale, were investigated in this study. Mineral composition analysis, organic matter analysis (including total organic carbon (TOC) content, maceral of kerogen and the vitrinite reflection (Ro)), pore characteristic analysis (including porosity and permeability, pore type identification by SEM, and pore size distribution by nitrogen sorption), methane isothermal sorption test were conducted, and the distribution and thickness of the shales were determined, Then the characteristics of the two target shales were illustrated and compared. The results show that the Upper Paleozoic shales have favorable organic matter conditions (mainly moderate to high TOC content, type I and II1 kerogen and high to over maturity), good fracability potential (brittleness index (BI) > 40%), multiple pore types, stable distribution and effective thickness, and good methane sorption capacity. Therefore, the Upper Paleozoic shales in the northern Guizhong Depression have good shale gas potential and exploration prospects. Moreover, the average TOC content, average BI, thickness of the organic-rich shale (TOC > 2.0 wt%) and the shale gas resources of the Middle Devonian shales are better than those of the Lower Carboniferous shale. The Middle Devonian shales have better shale gas potential and exploration prospects than the Lower Carboniferous shales.

Revenue Risk of U.S. Tight-Oil Firms

Directory of Open Access Journals (Sweden)

Luis Mª Abadie

2016-10-01

Full Text Available American U.S. crude oil prices have dropped significantly of late down to a low of less than $30 a barrel in early 2016. At the same time price volatility has increased and crude in storage has reached record amounts in the U.S. America. Low oil prices in particular pose quite a challenge for the survival of U.S. America’s tight-oil industry. In this paper we assess the current profitability and future prospects of this industry. The question could be broadly stated as: should producers stop operation immediately or continue in the hope that prices will rise in the medium term? Our assessment is based on a stochastic volatility model with three risk factors, namely the oil spot price, the long-term oil price, and the spot price volatility; we allow for these sources of risk to be correlated and display mean reversion. We then use information from spot and futures West Texas Intermediate (WTI oil prices to estimate this model. Our aim is to show how the development of the oil price in the future may affect the prospective revenues of firms and hence their operation decisions at present. With the numerical estimates of the model’s parameters we can compute the value of an operating tight-oil field over a certain time horizon. Thus, the present value (PV of the prospective revenues up to ten years from now is $37.07/bbl in the base case. Consequently, provided that the cost of producing a barrel of oil is less than $37.07 production from an operating field would make economic sense. Obviously this is just a point estimate. We further perform a Monte Carlo (MC simulation to derive the risk profile of this activity and calculate two standard measures of risk, namely the value at risk (VaR and the expected shortfall (ES (for a given confidence level. In this sense, the PV of the prospective revenues will fall below $22.22/bbl in the worst 5% of the cases; and the average value across these worst scenarios is $19.77/bbl. Last we undertake two

Economics of petroleum exploration offshore Australia and Southeast Asia

Allinson, G.; Elliston, M.

1994-01-01

The aim of this paper is to assess the economic attractiveness of exploring for crude oil offshore the North West Shelf of Australia by comparison with selected areas offshore Indonesia, Malaysia, Vietnam and the Philippines. In order to do this, the technical, quantifiable factors which affect offshore petroleum exploration acreage acquisition decisions at the country level are examined. These factors are historical prospectivity, costs of field development and fiscal regime. Other factors such as political, macro-economic and business risks are not considered. The paper concludes that there are significant differences between the countries as indicated by these measures. Past exploration in the Barrow/Dampier area of the North West Shelf of Australia has shown high levels of success by comparison with the other countries. It is estimated that this relatively high success rate coupled with comparatively low costs of field development and lenient fiscal regimes makes the economics of exploration on the North West Shelf favourable by comparison with those selected areas in the other countries considered. 5 tabs., 4 figs

The oil-dispersion bath in anthroposophic medicine--an integrative review.

Büssing, Arndt; Cysarz, Dirk; Edelhäuser, Friedrich; Bornhöft, Gudrun; Matthiessen, Peter F; Ostermann, Thomas

2008-12-04

Anthroposophic medicine offers a variety of treatments, among others the oil-dispersion bath, developed in the 1930s by Werner Junge. Based on the phenomenon that oil and water do not mix and on recommendations of Rudolf Steiner, Junge developed a vortex mechanism which churns water and essential oils into a fine mist. The oil-covered droplets empty into a tub, where the patient immerses for 15-30 minutes. We review the current literature on oil-dispersion baths. The following databases were searched: Medline, Pubmed, Embase, AMED and CAMbase. The search terms were 'oil-dispersion bath' and 'oil bath', and their translations in German and French. An Internet search was also performed using Google Scholar, adding the search terms 'study' and 'case report' to the search terms above. Finally, we asked several experts for gray literature not listed in the above-mentioned databases. We included only articles which met the criterion of a clinical study or case report, and excluded theoretical contributions. Among several articles found in books, journals and other publications, we identified 1 prospective clinical study, 3 experimental studies (enrolling healthy individuals), 5 case reports, and 3 field-reports. In almost all cases, the studies described beneficial effects - although the methodological quality of most studies was weak. Main indications were internal/metabolic diseases and psychiatric/neurological disorders. Beyond the obvious beneficial effects of warm bathes on the subjective well-being, it remains to be clarified what the unique contribution of the distinct essential oils dispersed in the water can be. There is a lack of clinical studies exploring the efficacy of oil-dispersion baths. Such studies are recommended for the future.

Lichens as indicators of the atmosphere state in the oil exploration district of Tomsk Region

Science.gov (United States)

Bolshunova, Tatiana; Ivan, Podkozlin

2013-04-01

Lichens are widespread in the vegetative cover of West Siberia, particularly in the north. They play an important role in the migration and transformation of chemical pollutants. Lichens lack waxy cuticles and are largely dependent on the atmosphere for their water and nutrient uptake. Lichens are not only studied and used as indicators, but also as accumulators, e.g. for trace and heavy metals. In fact, lichens are known for their ability to accumulate airborne substances to concentrations far greater those in the atmosphere, and the element contents of lichen thalli proved to be directly correlated with environmental levels. Monitoring of the atmosphere pollution using lichens is more efficient than that using snow cover. Because of the long lichen life it is possible to obtain persistent mean characteristics of the ecosystems state. Epiphytic lichens, growing on tree stems are more appropriate to use than that which grow on soil. Epiphytic lichens are more sensitive to changes of the chemical composition of the atmosphere. Pollutants penetrate in the lichen thalli from the atmosphere together with precipitations and dust. Moreover the precipitations are saturated with pollutants when going through crowns of trees and trickling down the steams and branches. Lichen studies are especially important in territories subjected to excessive human activity. Because a great part of Tomsk region (West Siberia, Russia) is the territory of the oil-field exploration, there the atmosphere monitoring is a necessary part of the whole environmental monitoring. The aim of this investigation is the estimation of the influence of oil exploration industry in Tomsk region on the atmosphere by means of the study of epiphytic lichens. Lichen samples were collected in August and September 2010-2011. Sampling net included seven areas distributed inside the oil-exploration districts of Tomsk region. In total 27 samples were collected. In these samples 53 chemical elements were detected by

Hydraulic Fracturing and Microseismicity: Global Perspective in Oil Exploration

Directory of Open Access Journals (Sweden)

J.R. Kayal

2017-09-01

Full Text Available Induced microseismicity is a common phenomenon in oil and gas reservoirs due to changes in internal stress accompanied by hydraulic fracturing and oil-gas extraction. These microseismicity can be monitored to understand the direction and type of hydraulic fracturing and pre-existing faults by precise hypocenter location and focal mechanism studies. Normal as well as strike-slip faulting earthquakes occur due to opening up of new cracks/fractures, and thrust/reverse faulting earthquakes due to compaction or closing of existing fractures. Further, frequency-magnitude relation (b-value and fractal dimension (D-value of the spatial and temporal clusterization of induced microseismicity may be much useful to characterize the fractures / existing faults and the stress regimes. Seismic tomography, on the other hand, can image the heterogeneous velocity structures / perturbations in the reservoir due to fractures and oil-gas-water contents. A few global case studies are illustrated to understand these processes and to draw attention towards importance of these studies in oil industries.

2010-02-15

The purpose of this paper is to analyse how oil export dependencies of Middle East and North African (MENA) oil producers have evolved over the past two decades and to identify the main driving factors from an energy policy perspective. The paper expresses the oil export dependency of each economy in terms of a multiplicative identity that captures effective export price, export to primary oil supply ratio, oil dependency and oil export intensity of the country. Using the data for 1980-2006, the evolution in these factors is investigated for seven MENA countries and the influence of the above factors is decomposed using the Laspeyres index. The analysis shows that energy price and increasing energy intensity in the MENA countries have influenced the overall oil export dependency. Reducing the energy intensity can improve oil export revenue share to GDP by 5-10% in most of the countries while Iran can gain significantly by increasing its export volume. (author)

Prospects for oil prices

International Nuclear Information System (INIS)

Caddy, P.

1992-01-01

It is argued that the wave in oil prices which occurred in 1991, although appearing to suggest price instability, in fact shows the opposite. Steady oscillation between a low price level that leads to new customers and a high price that encourages customers to switch to alternatives is a sign of a stable market. This relative stability was achieved against the background of the political upheaval in the USSR and Eastern Europe and its unpredictable consequences. Such political uncertainties to one side, the difficulties of assessing demand trends in the light of the imponderables of the state of the world economy and the weather are stressed. Despite these problems, the view is expressed that correct reading of signals up the supply chain by producers should ensure continued relative price stability. This is not to say that prices will stay exactly the same, just that they will be bound within a trading range set by anticipated consumer and producer responses to the fluctuating prices. (UK)

2001-01-01

Sequence stratigraphy has been widely used in hydrocarbon exploration and development, and great achievements have been achieved. However, its application to the prospecting for sandstone-type uranium deposits is just beginning. The metallogenic characteristics of sandstone-type uranium deposits and those of oil and gas are compared, and the relationship between sandstone-type uranium metallogenesis and the system tracts of sequence stratigraphy is studied. The authors propose that highest and system tracts are the main targets for prospecting interlayer oxidation zone type sandstone uranium deposits, and the incised valleys of low stand system tracts are favourable places for phreatic oxidation zone type sandstone uranium deposits, and transgressive system tracts are generally unfavorable to the formation of in-situ leachable sandstone-type uranium deposits. Finally, the authors look ahead the application potential of sequence stratigraphy to the prospecting for sandstone-type uranium deposits in continental depositional basins

Oil extraction from plant seeds for biodiesel production

Directory of Open Access Journals (Sweden)

Yadessa Gonfa Keneni

2017-04-01

Full Text Available Energy is basic for development and its demand increases due to rapid population growth, urbanization and improved living standards. Fossil fuels will continue to dominate other sources of energy although it is non-renewable and harm global climate. Problems associated with fossil fuels have driven the search for alternative energy sources of which biodiesel is one option. Biodiesel is renewable, non-toxic, environmental-friendly and an economically feasible options to tackle the depleting fossil fuels and its negative environmental impact. It can be produced from vegetable oils, animal fats, waste oils and algae. However, nowadays, the major feedstocks of biodiesel are edible oils and this has created food vs fuel debate. Therefore, the future prospect is to use non-edible oils, animal fats, waste oils and algae as feedstock for biodiesel. Selection of non-expensive feedstock and the extraction and preparation of oil for biodiesel production is a crucial step due to its relevance on the overall technology. There are three main conventional oil extraction methods: mechanical, chemical/solvent and enzymatic extraction methods. There are also some newly developed oil extraction methods that can be used separately or in combination with the conventional ones, to overcome some disadvantages of the conventional oil extraction methods. This review paper presents, compare and discusses different potential biofuel feedstocks, various oil extraction methods, advantages and disadvantages of different oil extraction methods, and propose future prospective for the improvement of oil extraction methods and sustainability of biodiesel production and utilization.

Prospects of application of vegetable oils as antifungal agents (Literature review

Directory of Open Access Journals (Sweden)

A. A. Mikheev

2017-04-01

Full Text Available Purpose of work – to summarize and present modern scientific literature reviews of alternative antifungal agents usage, among which herbal medicines, and in particular herbal oils, may play significant role. Fungal infections (mycoses are one of the leading infectious diseases in the world. Besides the medical importance, pathogenic fungi play a significant role in the food industry as potential pollutants. In order to treat fungal infections and to prevent food spoilage various medications that are products of chemical synthesis are widely used and the need for them increases significantly. However, among large number of medications and herbal drugs only a small part is used to treat fungal infections and to prevent food decay, though plants contain a lot of bioactive compounds with potential antifungal properties. Therefore, question of application of vegetable oils as antifungal agents is relevant. Various plants contain oils that have the potential antifungal properties, but are often used only in gastronomic purpose. The same time those oils can be successfully used for the treatment of candidiasis and infections caused by fungi of genera Aspergillus, Trichoderma, Penicillium, Fusarium, Metrhizium, Ophiostoma, Scopulariopsis and others. Their effects are manifested like using a single vegetable oil and mixtures of oils. Conclusions. Vegetable oils usage has big perspectives due to the lack of «addictive» effect and the development of resistance in fungi of different taxa. Vegetable oils do not require considerable investments for their reception, and thanks to traditions of aromo- and herbal medicine, their usage can be more effective in contrast to traditional chemotherapeutic agents. The search and study of new medicines based on vegetable oils may be a perspective direction of modern microbiological sciences and requires further deep studies of their biological properties and mechanisms of action.

Khadum Formation of Pre-Caucasus region as potential source of oil shales: geology and geochemistry

Directory of Open Access Journals (Sweden)

N.Sh. Yandarbiev1

2017-05-01

Full Text Available One of the main modern aim for oil industry is the development of hydrocarbon extraction technologies from «oil shale». In Russia there are kerogen-saturated carbonate-clayey-siliceous deposits of the Bazhenov Formation, carbonate rocks of the Volga-Ural and Timan-Pechora oil and gas bearing basins and clayey Maikop series of Pre-Caucasus region. The Khadum Formation is lower part of the Maikop series represented by carbonate-clay and clayey deposits. On the basis of long-term field and laboratory investigation conducted by specialists of the Oil and Gas Department from Geological Faculty of the Lomonosov Moscow State University. a comprehensive study of the lithological composition, structure, geochemical, hydrogeological and hydrodynamic characteristics of the Paleogene section and monitoring of the drilled wells, the prospects of the oil and gas potential of the Khadum deposits of the Oligocene in the Eastern Pre-Caucasus oil and gas bearing basin were estimated. 11 gas and 19 oil deposits are discovered within the Khadum deposits, and they are confined to the sand layers and lenses, but most of the Khadum section belongs to «unconventional» sources of hydrocarbons. Based on the integrated approach, a map of oil and gas potential prospects for the Khadum deposits was constructed. Highly prospective territories for drilling for oil, areas with small and medium perspectives, and gas prospecting areas have been singled out. Recommendations are given for drilling and technology for the development of the Pre-Caucasus oil shales, based on the world experience in the development of such formations.

Digitization of uranium deposit information in basin. A new strategy of ISL sandstone-type uranium deposits exploration

Tan Chenglong

2006-01-01

The discovered ISL sandstone-type uranium deposits in the entire world are mostly blind deposits, many of them occur in bleak desert, gobi desert, and semi-hilly land area. Exploration methods for these deposits mainly depend on great and systematic drilling. There are many large-medium size Meso-Cenozoic sedimentary basins in northern China, and over twenty of them are thick overburden basins which are mostly the virgin land for ISL sandstone-type uranium deposit. Due to the comprehensive national power, geological background, uranium exploration ability, great and systematic drilling is not favorable for prospecting ISL sandstone-type uranium deposit in China. According to the exploration and prospecting experiences for mineral ore bodies at home and abroad, uranium information mapping based on geochemical survey of the basins is a new strategy for ISL sandstone-type uranium deposits. It is an economic, practical, fast and effective method, and has been manifested by the performing information digitization for oil and gas resources, gold mineral resources in China and the mapping of uranium information for whole Europe continent.

2002-01-01

Full text:The presentation is is dedicated to summarizing the results of studying lithological and petrographic peculiarities and petrophysical properties of relatively scarcely studied rocks of lower Pliocene Kalinsky Series in Absheron, particularly its lower horizons, as well as to determining the regularities of these properties change about the area, as well as along the geological section. These generalisation cover the areas of Gala, Turkany, Gala-Dubendy, Govsany, Garachukhur, Bina, Zykh, Peschany island, Chilov, Khali, Gryazevaya sopka, Pirallakhy, and they are necessary for determining the direction of exploration and increasing the efficiency of productive horizons development. Kalinsky series is represented mostly by the alternation of siltstones, sandstones and shale and subjected to lithofacial changes along the section and about the area. In the reservoir sections studied Kalinsky series is mostly of polymetallic composition and is represented by badly sorted rocks. The sorting coefficient is within the range 2.5-4.7. Sands and sandstones occur relatively seldom. Thus, Kalinsky series, and its lower horizons in particular are scarcely studied. In some areas these horizons in particular are scarcely studied. In some areas horizons are not exposed. That is why for the purpose of oil and gas presence degree clarification it is necessary to resume exploration in Absheron oil and gas bearing region Kalinsky series, and in particular in its lower horizons

Empirical studies on changes in oil governance

Science.gov (United States)

Kemal, Mohammad

Regulation of the oil and gas sector is consequential to the economies of oil-producing countries. In the literature, there are two types of regulation: indirect regulation through taxes and tariffs or direct regulation through the creation of a National Oil Company (NOC). In the 1970s, many oil-producing countries nationalized their oil and gas sectors by creating and giving ownership rights of oil and gas resources to NOCs. In light of the success of Norway in regulating its oil and gas resources, over the past two decades several countries have changed their oil governance by changing the rights given to NOC from ownership right to mere access rights like other oil companies. However, empirical literature on these changes in oil governance is quite thin. Thus, this dissertation will explore three research questions to investigate empirically these changes in oil governance. First, I investigate empirically the impact of the changes in oil governance on aggregate domestic income. By employing a difference-in-difference method, I will show that a country which changed its oil governance increases its GDP per-capita by 10%. However, the impact is different for different types of political institution. Second, by observing the changes in oil governance in Indonesia , I explore the impact of the changes on learning-by-doing and learning spillover effect in offshore exploration drilling. By employing an econometric model which includes interaction terms between various experience variables and changes in an oil governance dummy, I will show that the change in oil governance in Indonesia enhances learning-by-doing by the rigs and learning spillover in a basin. Lastly, the impact of the changes in oil governance on expropriation risk and extraction path will be explored. By employing a difference-in-difference method, this essay will show that the changes in oil governance reduce expropriation and the impact of it is different for different sizes of resource stock.

Oil companies make cutbacks

Dupin, Ludovic

2014-01-01

As oil prices are falling, the oil sector faces company restructuring, merger projects, closure of oil fields, and so on. Restructuring is motivated by the costs of offshore exploration and oil production projects. Saudi Arabia tries to fight the emergence of shale gases by reducing oil prices, and somehow succeeds as some projects in the USA are put into question again. Experts perceive this situation as an opportunity for the sector to improve its efficiency and reduce over-staffing

Corruption and oil exploration: expert agreement about the prevention of HIV/AIDS in the Niger Delta of Nigeria

Udoh, Isidore A.; Stammen, Ronald M.; Mantell, Joanne E.

2008-01-01

The Niger Delta, according to the Nigerian Ministry of Health, has a disproportionately high HIV infection rate, which is double the national average. The United Nations Development Program attributes the spiraling HIV infection rate in the region to poverty, migration and gender inequality. This paper examines two complementary suppositions: Is the high prevalence of HIV in the Niger Delta related to incompetent leadership and corruption? Is it related to the negative effects of oil exploration in the region? Currently, there is a dearth of research on the effectiveness of government programs or the role of the oil industry on the impact of AIDS in Nigeria. To address this gap, we conducted a survey with 27 internationally renowned experts from diverse disciplines using a three-round modified Delphi to formulate consensus about the impact of weak governance and oil corruption on AIDS in the Niger Delta. Results from the Delphi suggest that these factors and others have exacerbated the transmission of HIV in the region. To mitigate the impact of AIDS in the region, efforts to engage oil companies in implementing HIV prevention programs as part of their corporate environmental responsibility to the community are urgently needed.

In the last 10 years, the success of shale gas and shale oil productions as a result of technological advances in horizontal drilling, hydraulic fracturing and nanoscale reservoir characterization have revolutionized the energy landscape in the United States. Resource assessment by the China Ministry of Land and Resources in 2010 and 2012 and by the U.S. Energy Information Administration in 2011 and 2013 indicates China’s shale gas resource is the largest in the world and shale oil resource in China is also potentially significant. Inspired by the success in the United States, China looks forward to replicating the U.S. experience to produce shale gas to power its economy and reduce greenhouse gas emissions. By 2014, China had drilled 400 wells targeting marine, lacustrine, and coastal swamp transitional shales spanning in age from the Precambrian to Cenozoic in the last five years. So far, China is the leading country outside of North America in the viable production of shale gas, with very promising prospects for shale gas and shale oil development, from the Lower Silurian Longmaxi marine shale in Fuling in the southeastern Sichuan Basin. Geological investigations by government and academic institutions as well as exploration and production activities from industry indicate that the tectonic framework, depositional settings, and geomechanical properties of most of the Chinese shales are more complex than many of the producing marine shales in the United States. These differences limit the applicability of geologic analogues from North America for use in Chinese shale oil and gas resource assessments, exploration strategies, reservoir characterization, and determination of optimal hydraulic fracturing techniques. Understanding the unique features of the geology, shale oil and gas resource potential, and reservoir characteristics is crucial for sweet spot identification, hydraulic fracturing optimization, and reservoir performance prediction.

The unpromising situation of terrestrial oil resources makes the deep-sea oil industry become an important development strategy. The South China Sea has a vast sea area with a wide distribution of oil and gas resources, but there is a phenomenon that exploration and census rates and oil exploitation are low. In order to solve the above problems, this article analyzes the geology, oil and gas exploration and exploration equipment in the South China Sea and the Gulf of Mexico. Comparing the political environment of China and the United States energy industry and the economic environment of oil companies, this article points out China’s deep-sea oil exploration and mining problems that may exist. Finally, the feasibility of oil exploration and exploitation in the South China Sea is put forward, which will provide reference to improve the conditions of oil exploration in the South China Sea and promoting the stable development of China’s oil industry.

Ethos and industry: a critical study of oil industry advertising from 1974-1984

Energy Technology Data Exchange (ETDEWEB)

Kurzbard, G.

1984-01-01

This study examines the advocacy advertising of the oil industry in general, and Mobil and Exxon Corporations in particular, during the years 1974-1984. The prospects of divestiture and nationalization of the industry, as a result of both gasoline shortages and exponential increases in profits which begin in the early seventies', created a profound concern by the majors that increasing public disaffection might result in legislation inimical to the industry. Mobil and Exxon's advertising attempted to provide a justification not only for their own operations, but for the entire American socio-economic system. The industry's value system was clearly reflected in its efforts to convince the public that its motives grew from an abiding commitment to the nation's well-being. The ideational underpinnings of oil industry discourse are traced through a rhetorical exploration of specific advertising campaigns. The study maintains that the weltanschauung of Big Oil is both directly and indirectly manifest in its advertising. An overall assessment of oil industry advertising is provided within a Burkean framework to treat of the textural elements of its discourse.

2014-01-01

Empty fruit bunch (EFB) from oil palm is one of the potential biomass to produce biofuels like bio-oil due to its abundant supply and favorable physicochemical characteristics. Confirming the assertion, this paper presents an overview of EFB as a feedstock for bio-oil production. The fundamental characteristics of EFB in terms of proximate analysis, ultimate analysis and chemical composition, as well as the recent advances in EFB conversion processes for bio-oil production like pyrolysis and solvolysis are outlined and discussed. A comparison of properties in terms of proximate analysis, ultimate analysis and fuel properties between the bio-oil from EFB and petroleum fuel oil is included. The major challenges and future prospects towards the utilization of EFB as a useful resource for bio-oil production are also addressed. - Highlights: • Palm EFB has high heating value and low greenhouse gas emissions during combustion. • Conversion of EFB to bio-oil is mainly by fast pyrolysis without and with catalyst. • Bio-oil from EFB is lower in heating value, heavier and more acidic than fuel oil. • The viscosity of bio-oil from EFB is between those of light and heavy fuel oils. • The flash and pour points of bio-oil from EFB are close to those of light fuel oil

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

Target post-evaluation of China's “12th Five-Year” oil and gas exploration and development planning and its “13th Five-Year” target prediction

Directory of Open Access Journals (Sweden)

Jiping Pan

2016-03-01

Full Text Available In the turn of 12th and 13th “Five-Year Plan” of China, the global oil and gas market changes greatly. In this regard, the target post-evaluation of the “12th Five-Year” oil and gas exploration and development planning was conducted, which is of significant importance to scientifically and reasonably making the specific “13th Five-Year” oil and gas exploration and development target planning. The post-evaluation results indicate that, in the period of “12th Five-Year Plan”, the oil and gas exploration and development targets of China were satisfactorily completed, but some deficiencies still existed. For example, the target of oil production (2 × 108 t was overfulfilled, while the target of oil reserves (65 × 108 t remained 6.4% outstanding. The target of gas reserves (3.5 × 1012 m3 was overfulfilled, while the target of gas production (1385 × 108 m3 remained 6.2% outstanding. Moreover, the targets of unconventional gases were not satisfactorily completed-shale gas being better than coalbed methane (CBM. Failures to fulfill some targets in “12th Five-Year Plan” were primarily attributed to the slowdown of oil and gas consumption growth, sharp drop of oil price, downgrading of resources, and changes of statistic basis under the new normal. The forecast results suggest that, in the period of “13th Five-Year Plan”, given USD50–70/bbl of world oil price, China's annual average incremental conventional oil and gas in place will be 10.0 × 108–12.0 × 108 t and 6000 × 108–8000 × 108 m3 respectively, annual average incremental shale gas and CBM in place will be 1000 × 108–2000 × 108 m3 and 500 × 108–1000 × 108 m3 respectively, and annual oil production will be about 2.0 × 108 t. By 2020, China's annual gas production will approach 1800 × 108–2000 × 108 m3 (shale gas: 200 × 108 m3, and CBM: 150 × 108 m3.

The main message contained in the report is summarised as follows: 'While prospects for the immediate future look good, we foresee a lack of new, important and technically challenging projects in the longer term. Discoveries made on the Norwegian Shelf during recent years have been small. Exploration activity must be intensified and its results must be improved. The most important and effective stimulus in this connection is new prospective exploration acreage. The Comprehensive Management Plan for Lofoten and the Barents Sea will be revised in 2010. By that time the knowledge gaps in the plan have to be filled so that the decision-making basis is as good as possible. Even though the level of activity looks as if it will continue to be high in the medium term, we have no time to lose.' Environmental status and challenges are briefly reviewed, as well as the industry's future recruitment challenges (author) (ml)

In the present study, a new method using near infrared spectroscopy combined with optical fiber sensing technology was applied to the analysis of hogwash oil in blended oil. The 50 samples were a blend of frying oil and "nine three" soybean oil according to a certain volume ratio. The near infrared transmission spectroscopies were collected and the quantitative analysis model of frying oil was established by partial least squares (PLS) and BP artificial neural network The coefficients of determina- tion of calibration sets were 0.908 and 0.934 respectively. The coefficients of determination of validation sets were 0.961 and 0.952, the root mean square error of calibrations (RMSEC) was 0.184 and 0.136, and the root mean square error of predictions (RMSEP) was all 0.111 6. They conform to the model application requirement. At the same time, frying oil and qualified edible oil were identified with the principal component analysis (PCA), and the accurate rate was 100%. The experiment proved that near infrared spectral technology not only can quickly and accurately identify hogwash oil, but also can quantitatively detect hog- wash oil. This method has a wide application prospect in the detection of oil.

As the world economy highly depends on crude oil, it is important to understand the dynamics of crude oil production and export capacity of major oil-exporting countries. Since crude oil resources are predominately located in the OPEC Middle East, these countries are expected to have significant leverage in the world crude oil markets by taking into account a range of uncertainties. In this study, we develop a scenario for crude oil export and production using the ACEGES model considering uncertainties in the resource limits, demand growth, production growth, and peak/decline point. The results indicate that the country-specific peak of both crude oil export and production comes in the early this century in the OPEC Middle East countries. On the other hand, they occupy most of the world export and production before and after the peak points. Consequently, these countries are expected to be the key group in the world crude oil markets. We also find that the gap between the world crude oil demand and production broadens over time, meaning that the acceleration of the development of ultra-deep-water oil, oil sands, and extra-heavy oil will be required if the world continuous to heavily rely on oil products. - Highlights: ► We simulate the future scenario of crude oil export and production using ACEGES. ► The simulated results are analyzed using the GAMLSS framework. ► The peak points of oil export and production will come early in this century. ► The OPCE Middle East will produce most of the world crude oil in the near future. ► These countries will continuously be the key players in the crude oil markets.

Waste-free processing of oil and oil gases can be based on electron-beam technologies. Their major advantage is an opportunity of controlled manufacturing of a wide range of products with a higher utility value at moderate temperatures and pressures. The work considers certain key aspects of electron beam technologies applied for the chain cracking of heavy crude oil, for the synthesis of premium gasoline from oil gases, and also for the hydrogenation, alkylation, and isomerization of unsaturated oil products. Electronbeam processing of oil can be embodied via compact mobile modules which are applicable for direct usage at distant oil and gas fields. More cost-effective and reliable electron accelerators should be developed to realize the potential of electron-beam technologies.

Exploration economics

International Nuclear Information System (INIS)

Mcgill, R.E.

1992-01-01

This paper deals with determining the economic viability of the play or prospect. At the outset, one point is important. Preexploration economists are important because they enable geologists to see if their assumptions will prove profitable. Their assumptions must consider the full range of possible outcomes, even if only some portion of that range may contain prospects or plays that are estimated to be profitable. Play economics are preferable to prospect economics because, being the sum of several prospects, they give a broader view of the investment opportunity. Finally, remember that play and prospect economics are always slightly optimistic. They seldom include all of the exploration and overhead changes that must ultimately be borne by the successful prospects

Production of renewable commodity chemicals from bio-oil derived from fast pyrolysis of biomass has received considerable interests, but hindered by the presence of innumerable components in bio-oil. In present work, we proposed and experimentally demonstrated an innovative approach combining atmospheric distillation of bio-oil with co-pyrolysis for mass production of renewable chemicals from biomass, in which no waste was produced. It was estimated that 51.86 wt.% of distillate just containing dozens of separable organic components could be recovered using this approach. Ten protogenetic and three epigenetic compounds in distillate were qualitatively identified by gas chromatography/mass spectrometry and quantified by gas chromatography. Among them, the recovery efficiencies of acetic acid, propanoic acid, and furfural were all higher than 80 wt.%. Formation pathways of the distillate components in this process were explored. This work opens up a fascinating prospect for mass production of chemical feedstock from waste biomass. PMID:23350028

After three years of crisis, oil companies are now strongly reinvesting, while oil prices are stabilizing at a reasonable long-term level, notably due to a rising demand from developing countries. Examples of new investments made by majors such as Total, Shell or Exxon but also by national companies and junior companies, are given. Oil price evolution as well as cost reductions (thanks notably to the digitalisation of the sector, leading to a decrease in exploration costs) are analyzed. The importance of the US oil production, and particularly shale oil production, is pinpointed

Quo Vadis Saskatchewan? Prospects to 2010

International Nuclear Information System (INIS)

Halabura, S.P.

2003-01-01

This presentation outlined the driving forces for Saskatchewan's upstream petroleum industry in terms of geology, technology and product price. The future direction of exploration and production was also explored. A timeline graph indicating oil and gas discoveries in the province from 1950 to 2000 was included along with graphs depicting the number of wells and prices. It was shown that the mass application of horizontal drilling technology resulted in an increase in production and a decrease in the price of well drilling. A timeline graph was also included to demonstrate the influence that different political regimes had on exploration and production. The hydrocarbon resource base in Saskatchewan is as follows: in the southeast, oil is found in carbonate rocks; in the southwest, oil and gas is found in sands and shales; and, in west-central Saskatchewan, heavy oil and gas is found in sands. The major basins include the Midale, Frobisher, Tilston, Madison, Shaunavon, Centaur, Roseray, White Specks, Mannville, Viking, and Bakken. Gas production prior to deregulation in 1985 was 12 per cent of the daily energy production. Gas production in 2002 was 25 per cent of the daily energy production. The future development potential for oil resources in the province lies in the deep Paleozoic carbonates. Huge original oil in place (OOIP) with low recovery rates offers great potential. The new tools and techniques that promote exploration include sequence stratigraphy applied to Paleozoic carbonates, seismic amplitude mapping, digital log analysis, diversifying carbon dioxide technology, gas liquefaction, and advanced reservoir characterization. 18 figs

Background Anthroposophic medicine offers a variety of treatments, among others the oil-dispersion bath, developed in the 1930s by Werner Junge. Based on the phenomenon that oil and water do not mix and on recommendations of Rudolf Steiner, Junge developed a vortex mechanism which churns water and essential oils into a fine mist. The oil-covered droplets empty into a tub, where the patient immerses for 15–30 minutes. We review the current literature on oil-dispersion baths. Methods The following databases were searched: Medline, Pubmed, Embase, AMED and CAMbase. The search terms were 'oil-dispersion bath' and 'oil bath', and their translations in German and French. An Internet search was also performed using Google Scholar, adding the search terms 'study' and 'case report' to the search terms above. Finally, we asked several experts for gray literature not listed in the above-mentioned databases. We included only articles which met the criterion of a clinical study or case report, and excluded theoretical contributions. Results Among several articles found in books, journals and other publications, we identified 1 prospective clinical study, 3 experimental studies (enrolling healthy individuals), 5 case reports, and 3 field-reports. In almost all cases, the studies described beneficial effects – although the methodological quality of most studies was weak. Main indications were internal/metabolic diseases and psychiatric/neurological disorders. Conclusion Beyond the obvious beneficial effects of warm bathes on the subjective well-being, it remains to be clarified what the unique contribution of the distinct essential oils dispersed in the water can be. There is a lack of clinical studies exploring the efficacy of oil-dispersion baths. Such studies are recommended for the future. PMID:19055811

Barite: a case study of import reliance on an essential material for oil and gas exploration and development drilling

Science.gov (United States)

Bleiwas, Donald I.; Miller, M. Michael

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.

Petroleum geological features and exploration prospect of deep marine carbonate rocks in China onshore: A further discussion

Directory of Open Access Journals (Sweden)

2014-10-01

Full Text Available Deep marine carbonate rocks have become one of the key targets of onshore oil and gas exploration and development for reserves replacement in China. Further geological researches of such rocks may practically facilitate the sustainable, steady and smooth development of the petroleum industry in the country. Therefore, through a deep investigation into the fundamental geological conditions of deep marine carbonate reservoirs, we found higher-than-expected resource potential therein, which may uncover large oil or gas fields. The findings were reflected in four aspects. Firstly, there are two kinds of hydrocarbon kitchens which were respectively formed by conventional source rocks and liquid hydrocarbons cracking that were detained in source rocks, and both of them can provide large-scale hydrocarbons. Secondly, as controlled by the bedding and interstratal karstification, as well as the burial and hydrothermal dolomitization, effective carbonate reservoirs may be extensively developed in the deep and ultra-deep strata. Thirdly, under the coupling action of progressive burial and annealing heating, some marine source rocks could form hydrocarbon accumulations spanning important tectonic phases, and large quantity of liquid hydrocarbons could be kept in late stage, contributing to rich oil and gas in such deep marine strata. Fourthly, large-scale uplifts were formed by the stacking of multi-episodic tectonism and oil and gas could be accumulated in three modes (i.e., stratoid large-area reservoir-forming mode of karst reservoirs in the slope area of uplift, back-flow type large-area reservoir-forming mode of buried hill weathered crust karst reservoirs, and wide-range reservoir-forming mode of reef-shoal reservoirs; groups of stratigraphic and lithologic traps were widely developed in the areas of periclinal structures of paleohighs and continental margins. In conclusion, deep marine carbonate strata in China onshore contain the conditions for

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

This paper assesses different strategies for the expansion of Brazil's oil refining segment, using criteria that range from energy security (reducing imports and vulnerability for key products) through to maximizing the profitability of this sector (boosting the output of higher value oil products) and adding value to Brazil's oil production (reducing exports of heavy acid oil). The development prospects are analyzed for conventional fuel production technology routes, sketching out three possible refining schemes for Brazilian oil and a GTL plant for producing gasoil from natural gas. Market scenario simulations indicate that investments will be required in Brazil's oil refining segment over and above those allocated to planned modifications in its current facilities, reducing the nation's vulnerability in terms of gasoil and petrochemical naphtha imports. Although not economically attractive, oil refining is a key activity that is crucial to oil company strategies. The decision to invest in this segment depends on local infrastructure conditions, environmental constraints and fuel specifications, in addition to oil company strategies, steady growth in demand and the definition of a government policy that eases institutional risks.

In China it is important to explore coal prospecting by taking advantage of modern remote sensing and geographic information system technologies. Given a theoretical basis for coal prospecting by remote sensing, the methodologies and existing problems are demonstrated systematically by summarizing past practices of coal prospecting with remote sensing. A new theory of coal prospecting with remote sensing is proposed. In uncovered areas, coal resources can be prospected by direct interpretation. In coal bearing strata of developed areas covered by thin Quaternary strata or vegetation, prospecting for coal can be carried out by indirect interpretation of geomorphology and vegetation. For deeply buried underground deposits, coal prospecting can rely on tectonic structures, interpretation and analysis of new tectonic clues and regularity of coal formation and preservation controlled by tectonic structures. By applying newly hyper-spectral, multi-polarization, multi-angle, multi-temporal and multi-resolution remote sensing data and carrying out integrated analysis of geographic attributes, ground attributes, geophysical exploration results, geochemical exploration results, geological drilling results and remote sensing data by GIS tools, coal geology resources and mineralogical regularities can be explored and coal resource information can be acquired with some confidence. 12 refs., 4 figs., 3 tabs.

Among the geological and geochemical methods for prospecting and searching the nuclear raw material, the isotope-dating methods determine the most important search criterion - the time of the ore-forming. The elaboration and use of these methods in uranium-ore regions reveal a series of geochemical epochs of uranium and thorium accumulation connected naturally with the history of geological evolution of the earth crust. The isotope-dating methods enable with confidence to establish the stages of tectono-magmatic activity resulting in the redistribution and the local concentration of uranium. The wide use of isotopic methods is a necessary condition for reasonable trends of the modern geological exploration [ru

Oil frontiers and indigenous resistance in the Peruvian Amazon

The Peruvian Amazon is culturally and biologically one of the most diverse regions on Earth. Since the 1920s oil exploration and extraction in the region have threatened both biodiversity and indigenous peoples, particularly those living in voluntary isolation. We argue that the phenomenon of peak oil, combined with rising demand and consumption, is now pushing oil extraction into the most remote corners of the world. Modern patterns of production and consumption and high oil prices are forcing a new oil exploratory boom in the Peruvian Amazon. While conflicts spread on indigenous territories, new forms of resistance appear and indigenous political organizations are born and become more powerful. The impacts of oil exploration and exploitation and indigenous resistance throughout the oil history of the Peruvian Amazon are reviewed here, focusing on the Achuar people in Rio Corrientes. The driving forces, impacts, and responses to the current oil exploration boom are analyzed from an environmental justice perspective. We conclude that, in a context of peak oil and growing global demand for oil, such devastating effects for minor quantities of oil are likely to increase and impact other remote parts of the world.

The purpose of this study was to assess the major risk factors for hypertension in oil workers, and investigate the effect of occupational stress on the incidence of hypertension after controlling for other risk factors. A prospective cohort approach was used following enrollment of 1354 oil workers. The occupational stress experienced by oil workers was higher than for the general population in China. By the end of the cohort study, 231 new cases of hypertension among the oil workers had been diagnosed. The cumulative incidence of hypertension was 17.06%. There were 44, 112, and 75 workers who developed hypertension in the low, intermediate, and high occupational stress groups, which represented a 12.0%, 15.6%, and 20.3% cumulative incidence, respectively (chi-square value = 9.812, p occupational stress group was 1.549 (1.072-2.236) compared to the low exposure group, and 2.337 (1.191-4.585) in female subjects. Our study indicated that an increase in occupational stress was associated with an increased risk of hypertension after other factors were adjusted.

International hotspots of Canadian exploration and production companies are described. Examples of mid-sized Canadian companies competing successfully in many parts of the world are recounted. Being Canadian and having access to countries that Americans do not because of trade sanctions, allows Canadian companies to bring to these countries all the North American technology without the associated politics. Successes by Canadian Occidental Petroleum in Yemen, in Africa, the former Soviet Union and South America, or Alberta Energy Company International's recent commitment to explore in Azerbaijan with estimated reserves of 5.9 billion barrels of oil-equivalent, are only some of the examples where Canadian explorers have been very successful. Some of the problems faced by international operators such as scarcity of indigenous trained personnel, lack of infrastructure, unstable governments, and/or unfriendly government policies, tribal wars, unfavourable public reaction 'back home' to repressive regimes in parts of the world ( e.g. Talisman Energy in Sudan) are some of the dangers faced by companies venturing into the global arena, driven by dreams of untold riches, but also by the prospects of diminishing reserves on home turf.

Dingle, H. B.

1999-01-01

Imperial Oil Limited's Cold Lake oil sands resources, production and operations in Alberta are discussed. Cold Lake is the company's largest single asset and its largest source of crude oil production. In 1998, Cold Lake accounted for just under half of Imperial's total liquid production, averaging more than 135,000 barrels of bitumen a day. Despite the very difficult operating conditions experienced by the oil sands industry in 1998, Imperial Oil's Cold Lake operations generated a positive cash flow and earnings. Just as important, the near and long-term potential of Cold Lake property continues to be strong, even with the tough market conditions today and the foreseeable future. Proved reserves at the end of 1997 were 1.3 billions barrels, equal to about 24 years of current production, but even more important is Imperial's resource base in the Athabasca region, which represents 150 years of production at current rates. Although production forecasts for the near future are are revised downward because of production shut-in due to low prices, the company is confident of its long-term prospects mainly because of existing infrastructure, superior reservoir quality, 30 years worth of operating improvements and established bitumen-blend markets. Details of the company's future Cold Lake development plans are discussed. The need to continue technology development, which has been at the core of the industry's growth in the past and will continue to be the key to the future, are emphasized

The goal of this program was to develop a revolutionary solid-state gamma-ray detector suitable for use in down-hole gas and oil exploration. This advanced detector would employ wide-bandgap semiconductor technology to extend the gamma sensor's temperature capability up to 200 C as well as extended reliability, which significantly exceeds current designs based on photomultiplier tubes. In Phase II, project tasks were focused on optimization of the final APD design, growing and characterizing the full scintillator crystals of the selected composition, arranging the APD device packaging, developing the needed optical coupling between scintillator and APD, and characterizing the combined elements as a full detector system preparing for commercialization. What follows is a summary report from the second 18-month phase of this program

Exploring the reference point in prospect theory: gambles for length of life.

Science.gov (United States)

van Osch, Sylvie M C; van den Hout, Wilbert B; Stiggelbout, Anne M

2006-01-01

Attitude toward risk is an important factor determining patient preferences. Risk behavior has been shown to be strongly dependent on the perception of the outcome as either a gain or a loss. According to prospect theory, the reference point determines how an outcome is perceived. However, no theory on the location of the reference point exists, and for the health domain, there is no direct evidence for the location of the reference point. This article combines qualitative with quantitative data to provide evidence of the reference point in life-year certainty equivalent (CE) gambles and to explore the psychology behind the reference point. The authors argue that goals (aspirations) in life influence the reference point. While thinking aloud, 45 healthy respondents gave certainty equivalents for life-year CE gambles with long and short durations of survival. Contrary to suggestions from the literature, qualitative data argued that the offered certainty equivalent most frequently served as the reference point. Thus, respondents perceived life-year CE gambles as mixed. Framing of the question and goals set in life appeared to be important factors behind the psychology of the reference point. On the basis of the authors' quantitative and qualitative data, they argue that goals alter the perception of outcomes as described by prospect theory by influencing the reference point. This relationship is more apparent for the near future as opposed to the remote future, as goals are mostly set for the near future.

Full Text Available This study investigated prospective mathematics teachers’ reflections on the experience of designing and conducting one-to-one clinical interviews with middle school students in the context of an elective course on use of video in teacher learning. Prospective teachers were asked to write about weaknesses and strengths in student understanding as well as their own performance as an interviewer in terms of asking questions and responding to student thinking in their reflections on conducting clinical interviews. Furthermore, prospective teachers were also asked to reflect on what they would do differently in order to conduct better clinical interviews. Nature of prospective teachers’ reflections were analyzed by using existing frameworks (through constructs of reflection-on-action and reflection-for-action and by using thematic analysis. Results of data analyses revealed that prospective teachers had more difficulties in providing meaningful reflection-for-action which was related to alternative decisions and planning for future similar interviews. Thematic analysis results revealed prospective teachers’ learning were grouped under three categories: conducting clinical interviews as part of being a teacher, complexity of conducting clinical interviews, and personal theories about middle school students. There are implications for both teacher learning and research.

Development of oil supply and demand planning model for mid- and long-term

Energy Technology Data Exchange (ETDEWEB)

Kim, Sung Hyun [Korea Energy Economics Institute, Euiwang (Korea)

1997-10-01

Despite the liberalization of oil market, a systematic model is required for reasonable supply and demand of oil, which still has an important influence on industry and state economy. It is required a demand model deriving prospects of each sector and product and a supply model examining the optimum rate of operation, production mix of products, stock, export and import, and the size of equipment investment to meet given demand. As the first phase for the development of supply and demand model, the existing oil and energy models in domestic and overseas were reviewed and recommendations for establishing a Korean oil supply and demand model were derived in this study. Based on these, a principle for establishing a model and a rough framework were set up. In advance of mid- and long-term prospects, a short-term prospect model was established and the short-term prospects for the first quarter of 1999 and for the year 1999 were presented on trial. Due to the size and characters of a supply model, a plan for an ideal model was first explained and then a plan for creating a model step by step was presented as a realistic scheme.

The oil and oil services industry international context 2008

International Nuclear Information System (INIS)

Serbutoviez, S.; Silva, C.

2008-11-01

Oil companies rarely do their own major work within the framework of their investments or in the operation of their facilities. They most often act as project coordinators, thereby opening up a vast market for equipment, services and engineering, involving many companies of widely-varying sizes, which constitute the oil services industry. This document provides a panorama of the international oil context in three distinct parts, for 2007, for the first three quarters of 2008, and aspects of trends for 2009. - The first part is devoted to a rapid description of the oil context and the economic environment in which it is evolving. - The second part examines the evolution of world investment in exploration-production (E and P) activities, distinguishing the investments made by oil and oil product/service companies throughout the E and P chain from the more targeted ones of three specific sectors: seismic, drilling and the construction of offshore production equipment. These markets are observed exclusively for oil product/service companies. - The last part is devoted to investments in the refining sector, focusing on the changes in the fundamentals, particularly the equilibrium between refining capacities and medium- term oil demand. This latter analysis involves both oil and oil product/service companies. (authors)

Positive organizational behavior and safety in the offshore oil industry: Exploring the determinants of positive safety climate.

Science.gov (United States)

Hystad, Sigurd W; Bartone, Paul T; Eid, Jarle

2014-01-01

Much research has now documented the substantial influence of safety climate on a range of important outcomes in safety critical organizations, but there has been scant attention to the question of what factors might be responsible for positive or negative safety climate. The present paper draws from positive organizational behavior theory to test workplace and individual factors that may affect safety climate. Specifically, we explore the potential influence of authentic leadership style and psychological capital on safety climate and risk outcomes. Across two samples of offshore oil-workers and seafarers working on oil platform supply ships, structural equation modeling yielded results that support a model in which authentic leadership exerts a direct effect on safety climate, as well as an indirect effect via psychological capital. This study shows the importance of leadership qualities as well as psychological factors in shaping a positive work safety climate and lowering the risk of accidents.

Soviet Union oil sector outlook grows bleaker still

1991-01-01

This paper reports on the outlook for the U.S.S.R's oil sector which grows increasingly bleak and with it prospects for the Soviet economy. Plunging Soviet oil production and exports have analysts revising near term oil price outlooks, referring to the Soviet oil sector's self-destructing and Soviet oil production in a freefall. County NatWest, Washington, citing likely drops in Soviet oil production and exports (OGJ, Aug. 5, p. 16), has jumped its projected second half spot price for West Texas intermediate crude by about $2 to $22-23/bbl. Smith Barney, New York, forecasts WTI postings at $24-25/bbl this winter, largely because of seasonally strong world oil demand and the continued collapse in Soviet oil production. It estimates the call on oil from the Organization of Petroleum Exporting Countries at more than 25 million b/d in first quarter 1992. That would be the highest level of demand for OPEC oil since 1980, Smith Barney noted

Application of Satellite SAR for Discovery and Quantification of Natural Marine Oil Seeps

Science.gov (United States)

Amos, J.; Lai, R.; Zimmer, B.; Leiva, A.; MacDonald, I.

2006-12-01

Natural marine oil seeps discharge gassy drops from the seafloor. Oil drops and gas bubbles reach the surface from water depths as great as 3000m. The oil spreads rapidly, forming an invisible layer that drifts down-wind and down-current in long, linear streaks called slicks. Oil slicks are visible in SAR data because the surfactant dampens capillary waves and reduces backscatter. Application of SAR as an exploration tool in energy prospecting is well-established. We have applied this technique for discovering the chemosynthetic communities that colonize the seafloor in the vicinity of deep-water seeps on the continental margin of the Gulf of Mexico. The management goal for this effort is to prevent harmful impact to these communities resulting from exploration or production activities. The scientific goals are to delineate the zoogeography of the chemosynthetic fauna, which is widespread on continental margins, and to establish study sites where their life history can be investigated. In the course of an ongoing, multidisciplinary study in the spring and summer of 2006, we explored 20 possible sites where SAR and geophysical data indicated seeps might occur. SAR was only partly diagnostic: all sites with SAR-detected slicks were found to have biologic communities, but communities were also found at geophysical anomalies that did not produce slicks. We acquired over 60 RADARSAT SAR images from the northern Gulf of Mexico in cooperation with the Alaska Satellite Facility. The ship RV ATLANTIS was at sea during the acquisition and collected synoptic weather and oceanographic data. To automate interpretation of large image dataset we have employed texture recognition with use of a library of textons applied iteratively to the images. This treatment shows promise in distinguishing floating oil from false targets generated by rain fronts and other phenomena. One goal of the analysis is to delineate bounding boxes to quantify the ocean area covered by the thin oil layer

Using comprehensive two-dimensional gas chromatography to explore the geochemistry of the Santa Barbara oil seeps

Energy Technology Data Exchange (ETDEWEB)

Reddy, Christopher; Nelson, Robert

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.

Spaulding, M.L.; Reed, M.

1990-01-01

Public awareness and concern for the potential short and long term impacts of oil spills on the marine environment has generally been high, particularly for regions of special ecological importance or where significant numbers of marine mammals and birds are present. This awareness was further heightened by the extraordinary number of recent large spills in coastal U.S. water: Exxon Valdez, Alaska; World Prodigy, Rhode Island; Presidente Rivera, Delaware; Rachel-B, Texas and American Trader, California. The occurrence of so many spills in a one year period is unprecedented in U.S. spill history. The legislative response to these spills has been immediate. New legislative initiative are rapidly being developed. Improved ways to organize spill response efforts are being devised and implemented. Funds are being allocated to further develop and improve spill response equipment and damage assessment methodologies. These spill events will have a significant impact in both the short and long term on oil exploration, development and transport in marine waters. They will result in major changes in management and operation of oil exploration and development. The purpose of this conference was to provide a forum for discussion of the changes which are currently taking place in oil spill legislation, management, and response strategies

Korostyshevskiy, M.B.; Nabokov, G.N.

1981-01-01

The basic precepts of an elaborated version of a procedure for forecasting (direct exploration) of oil and gas deposits according to seismic prospecting data MOV are examined. This procedure was previously called the procedure of analysis of the integral affect of an oil and gas deposit in a seismic wave field (MIIEZ-VP). The procedure is implemented in the form of an automated system ASOM-VP for the BESM-4 computer in a standard configuration equipped with standard input-output devices for seismic information (''Potok'', MVU, ''Atlas''). The entire procedure of processing from input of data into the computer to output of resulting maps and graphs on graph plotter ''Atlas'' is automated. Results of testing of procedure MIIEZ-VP and system ASOM-VP on drilled areas of Kazakhstan, Azerbaydzhan and Uzbekistan are cited.

Environmental issues facing the oil industry

International Nuclear Information System (INIS)

Skea, Jim

1992-01-01

Environmental policies and regulations are having profound effects on the oil industry. The industry is affected by controls on both its production and processing activities and on the use of its own products. The environmental impacts of upstream activities, epitomized by the Exxon Valdez accident, are leading to more expensive tanker designs. Oil markets can be changed by sulphur controls driven by concern about acid rain and new requirements in the USA to change gasoline specifications in order to reduce urban smog. The problem of climate change and CO 2 emissions poses even more fundamental challenges to the oil industry, with the prospect of reduced markets in the longer term. (author)

Regulatory Framework on Exploration and Exploitation of Croatian Part of Adriatic

International Nuclear Information System (INIS)

Mudric, M.

2015-01-01

As the prelude to the regulation of marine exploration and exploitation activities in the Croatian Adriatic waters, the new Mining Act and Act on exploration and exploitation of hydrocarbons have provided a general legal framework for the natural resources exploration and exploitation. The latter Act also appropriated the establishment of the independent regulatory body, the Hydrocarbon Agency. It is important to mention the Decree on Fees for exploration and production of hydrocarbons, and the Decree on main technical requirements on safety and security of offshore exploration and production of hydrocarbons in the Republic of Croatia, that are of special relevance for the current activities with regard the proposed project of exploration and exploitation of the Croatian waters in search for gas and oil sea-bed deposits. The Hydrocarbon Agency has published the Strategic Study of the Likely Significant Environmental Impact of the Framework Plan and Program of Exploration and Production of Hydrocarbons in the Adriatic, a document receiving a lot of criticism from the legal experts and general public. At the same time, the experts tend to support the general idea of sea-bed exploration and exploitation, with the major antagonism still being present in the general public, with several initiatives introducing the possibility of a public referenda to oppose the sea-bed exploration and exploitation. The Government is currently preparing the Act on the Safety of Offshore Hydrocarbon Exploration and Production Operations, based on the Directive 94/22/EC of the European Parliament and of the Council of 30 May 1994 on the conditions for granting and using authorizations for the prospection, exploration and production of hydrocarbons, the Commission Implementing Regulation (EU) No 1112/2014 of 13 October 2014 determining a common format for sharing of information on major hazard indicators by the operators and owners of offshore oil and gas installations and a common format

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

1990-10-01

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

The goal of this program was to develop a revolutionary solid-state gamma-ray detector suitable for use in down-hole gas and oil exploration. This advanced detector would employ wide-bandgap semiconductor technology to extend the gamma sensor's temperature capability up to 200 C as well as extended reliability, which significantly exceeds current designs based on photomultiplier tubes. In Phase II, project tasks were focused on optimization of the final APD design, growing and characterizing the full scintillator crystals of the selected composition, arranging the APD device packaging, developing the needed optical coupling between scintillator and APD, and characterizing the combined elements as a full detector system preparing for commercialization. What follows is a summary report from the second 18-month phase of this program.

2008-10-15

Biodiesel has become more attractive recently because of its environmental benefits, and the fact that it is made from renewable resources. Generally speaking, biodiesel is prepared through transesterification of vegetable oils or animal fats with short chain alcohols. However, the lack of oil feedstocks limits the large-scale development of biodiesel to some extent. Recently, much attention has been paid to the development of microbial, oils and it has been found that many microorganisms, such as algae, yeast, bacteria, and fungi, have the ability to accumulate oils under some special cultivation conditions. Compared to other plant oils, microbial oils have many advantages, such as short life cycle, less labor required, less affection by venue, season and climate, and easier to scale up. With the rapid expansion of biodiesel, microbial oils might become one of potential oil feedstocks for biodiesel production in the future, though there are many works associated with microorganisms producing oils need to be carried out further. This review is covering the related research about different oleaginous microorganisms producing oils, and the prospects of such microbial oils used for biodiesel production are also discussed.

Oil supply and oil politics: Deja Vu all over again

International Nuclear Information System (INIS)

Cleveland, Cutler J.; Kaufmann, Robert K.

2003-01-01

President Bush has identified US dependence on imported oil as an urgent energy, economic, and national security concern. The President's energy plan promotes the development of domestic resources, based on the assumption that economic incentives and the opening of frontier areas for exploration will increase domestic production. If realized, this will reduce dependence on imported oil and reduce OPEC's ability to affect aggregate oil supply and price. The evidence suggests, however, that this policy will not increase significantly US production of crude oil, will not reduce significantly OPEC's influence, and it will distort the US macroeconomy. Even if allowed, production from the Arctic National Wildlife Refuge will have a negligible impact on the world oil markets. Further subsidies to the oil industry will divert resources from other more productive investments. Conservation and energy efficiency merit greater emphasis in US energy policy given their ability to reduce the use of cost-effective and environmentally beneficial ways

Exploration and development at crossroads in Ecuador

International Nuclear Information System (INIS)

Anon.

1992-01-01

This paper reports that Ecuador's oil and gas sector has reached a pivotal point in its history. After several years of fairly brisk activity, foreign operators recently began scaling back exploration in Ecuador. They cited results that haven't met expectations and persistent delays in obtaining approval by state owned Petroecuador for development of reserves that have been discovered. Foreign oil companies had anticipated the pace of development would accelerate in Ecuador in early 1992, but major projects generally remained in limbo for most of this year. At presstime, however, there were signs of an encouraging follow-through in promised reforms in the permitting process. Petroecuador in April-May approved two of those projects and a third in June. Of the 13 oil companies or groups that had signed exploration contracts with the state oil company since 1985, several companies have terminated their operations in the country, and only one company, Oryx Energy Co., Dallas, is producing a small volume of oil. Two other companies have been negotiating exploration rights for about 2 years, with contracts yet to be signed

This report gives the results of an assessment of the effects on seabirds of possible petroleum exploration at the shelf outside Central-Norway out to 1 o East. By combining oil spill simulations with the valued ecosystem components, i.e. seabirds, their distribution, and their vulnerability indexes, the relative index values for the direct effects of oil spills were calculated. For the purpose, the analysis system SIMPACT was used. On the basis of these results and other relevant considerations, recommendations for limiting a possible drilling activity are given. 85 refs., 49 figs., 9 tabs

Japan's involvement in oil sands development

International Nuclear Information System (INIS)

Sugiura, T.

1994-01-01

According to Japanese national policy, exploration and development by Japanese companies in overseas countries are promoted in order to ensure stable oil supplies. Japan Canada Oil Sands Limited (JACOS), part of the JAPEX group, was established during the 1978 world oil crisis to explore and develop Canadian oil sand resources in accordance with Japan's national policy. The JAPEX group, including JACOS, has invested $123 million in oil sands projects in Alberta. JAPEX's first involvement in oil sands was in the Primrose Project operated by Norcen in the Cold Lake area. Five years of cyclic steam stimulation pilot tests did not produce sufficiently good results to justify further operation. The second involvement was the PCEJ Project, a joint effort by four companies that are participating in a bitumen recovery test project in the Athabasca Deposit. JACOS holds 2,452 km 2 of oil sands leases in Alberta. Tests conducted since 1978 in the PCEJ Project include multiwell steam injection pilot tests, some of which showed promise. JACOS is also participating in steam assisted gravity drainage projects and in federal/provincial research programs. Obstacles identified in developing Alberta oil sands are the lack of a bitumen pipeline to Edmonton and the insufficient length of oil sands leases (currently 10 years), given the difficulties of oil sand development. 10 figs

The primary purpose of mineral exploration is to discover ore deposits. The emphasis of this volume is on the mathematical and computational aspects of optimizing mineral exploration. The seven chapters that make up the main body of the book are devoted to the description and application of various types of computerized geomathematical models. These chapters include: (1) the optimal selection of ore deposit types and regions of search, as well as prospecting selected areas, (2) designing airborne and ground field programs for the optimal coverage of prospecting areas, and (3) delineating and evaluating exploration targets within prospecting areas by means of statistical modeling. Many of these statistical programs are innovative and are designed to be useful for mineral exploration modeling. Examples of geomathematical models are applied to exploring for six main types of base and precious metal deposits, as well as other mineral resources (such as bauxite and uranium)

Offsite commercial disposal of oil and gas exploration and production waste :availability, options, and cost.

Puder, M. G.; Veil, J. A.

2006-09-05

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

The current and short term outlook for offshore exploration and development in the UK

International Nuclear Information System (INIS)

Precious, R.G.

1992-01-01

The United Kingdom offshore oil and gas industry began with the first North Sea discoveries in 1965. Of the total estimated hydrocarbon resources, 34% of the 32 billion bbl of oil and gas liquids and 23% of the 124 trillion ft 3 of natural gas have already been produced, and an additional 22% and 23% respectively are currently producing or under development. Average discovery size has declined as the region matures; nevertheless drilling activity has remained high. Low oil prices, increasing operating costs, and the worldwide recession have caused many companies to cut back on capital expenditures. The outlook for North Sea exploration is for smaller, more complex prospects and in areas with greater exploration potential. The outlook for development is for smaller, often economically marginal new fields and existing fields that are increasingly expensive to operate. In new fields, costs can be reduced by simplification and standardization of facilities, using horizontal drilling, lighter modular platforms, subsea technology, and multiphase pipelines. Examples of such developments at Shell/Esso's Osprey and Gannet fields are described. In existing fields, emphasis is on upgrading of facilites for extended field life; simplification and automation of facilities is also being carried out to reduce costs. Examples are provided from Shell/Esso's Brent and Leman fields. Other factors affecting future development are outlined. Total U.K. gas demand is forecast to rise to 7-8 billion ft 3 d by the late 1990s; imports may be required to meet total U.K. demand at that time.

This special issue of the journal examines various aspects of the on-going search for hydrocarbons, ranging from frontier basins where little data are available, to more mature areas where considerable data are available. The incentives underlying the search for oil are roughly: the social, economic and industrial needs of a nation; the incentive of a corporation to be profitable; and the personal incentives of individuals in the oil industry and governments, which range from financial wealth to power and which are as diverse as the individuals who are involved. From a geopolitical perspective, the needs, requirements, goals, strategies, and philosophies of nations, and groups of nations, also impact on the oil exploration game. Strategies that have been employed have ranged from boycott to austerity and rationing, to physical intervention, to global ''flooding'' with oil by over-production. (author)

Exploration economics in a regulated petroleum province: The case of the Norwegian Continental Shelf

International Nuclear Information System (INIS)

Mohn, Klaus; Osmundsen, Petter

2008-01-01

Reserve replacement remains a key challenge for the international oil and gas companies. As market-oriented oil and gas provinces are maturing, exploration activity is shifted towards the resource-rich, regulated regimes outside the OECD. Regulated oil and gas provinces remain under-explored also in econometric terms. In this paper, we specify and estimate an econometric model of exploration and appraisal drilling for the highly regulated Norwegian Continental Shelf (NCS) over the period 1965 to 2004. Explanatory variables include the oil price, cumulative discoveries and open exploration acreage. Estimated error-correction models account explicitly for sluggishness and short-term adjustments in exploration drilling. We find robust long-term oil price effects on exploration activity, whereas the short-term response is muted. On the other hand, the temporary influence on exploration drilling from licensing rounds for new exploration acreage is significant, and so are the feedback effects from historical exploration success. At the same time, the longer-term impact of these variables is more moderate. (author)

BIOLOGICALLY ACTIVE COMPOUNDS OF ARTEMISIA ANNUA. ESSENTIAL OIL

2016-01-01

Full Text Available Artemisia annua is a herblike annual plant which has been used in Chinese folk medicine for more than 2,000 years. In 1970-s sesquiterpenic lactone of artemisinin was isolated from the above-ground part of this plant. Today it is the most efficient known natural and synthetic compound for malaria treatment. The purpose of the study was to review the data from the open sources about a component composition of Artemisia annua essential oil in the spectrum of its pharmacological activity. Methods. The study was carried out using information and searching sources (PubMed, ScholarGoogle, library data bases (eLibrary, Cyberleninca, as well as the results of our studies. Results. We have established that aboveground part of Artemisia annua have a significant amount  of essential oil apart from the sesquiterpene lactones. Essential oil contains more than 120 components, which belong to different classes of natural compounds. The study for dynamics of the essential oil accumulation in the Artemisia annua herb showed that the amount of oil in the herb rises significantly during budding, reaching maximum value in blossom. Qualitative composition and quantitative content of certain components varies depending on ecological and  geographical factors,  plant growing phase, cultivation technology, drying methods etc. Well-known pharmacological studies of essential oil of the Artemisia annua characterize it as a prospective source for the development of new antimicrobial medicinal drugs. Besides, as the studies shown, it can be related to the 6 class according to K. Sidorov’s classification – “relatively non-hazardous substances”. Conclusion. The analysis of the open sources on the study of essential oil of Artemisia annua made by us, as well as the results of our own studies, including phytochemical studies allow characterizing the essential oil of Artemisia annua as a prospective source for the working out of new antimicrobial drugs.

Will the 21. century be the petroleum challenge century? The petroleum problem is no longer the affair of experts and journalists, it challenges also governments and consumers in pressing terms. If there is today a petroleum problem, there is no oil or gas shortage for the moment. The cumulated oil and gas reserves would allow to face the demand of the century, with the condition that investments in exploration, field development, production, and back-end of oil and gas industries will be done in time. This book, written by specialists of energy economics and geopolitics shows up some of the key questions of our energy future. In particular, it invites us to never forget the basic heavy trends of the hydrocarbons sector in order to never be trapped by superficial extrapolations of short term phenomena. Content: heavy trend of oil prices at the 2020 prospects, natural gas take over?; oil and gas geopolitics: enough of hydrocarbons for the 21. century; Russia and Caspian sea oil and gas weight; China: a new strategic actor of the energy scene; influence of 'futures' market, of speculation, and of stocks on hydrocarbon prices; which future for LNG?; natural gas in the USA: towards a new foreign dependence.

To evaluate the consumption of added fats and oils across the European centres and countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). 24-Hour dietary recalls were collected by means of standardised computer-guided interviews in 27 redefined EPIC centres across 10 European countries. From an initial number of 36 900 subjects, single dietary recalls from 22 924 women and 13 031 men in the age range of 35-74 years were included. Mean daily intake of added fats and oils varied between 16.2 g (Varese, Italy) and 41.1 g (Malmö, Sweden) in women and between 24.7 g (Ragusa, Italy) and 66.0 g (Potsdam, Germany) in men. Total mean lipid intake by consumption of added fats and oils, including those used for sauce preparation, ranged between 18.3 (Norway) and 37.2 g day-1 (Greece) in women and 28.4 (Heidelberg, Germany) and 51.2 g day-1 (Greece) in men. The Mediterranean EPIC centres with high olive oil consumption combined with low animal fat intake contrasted with the central and northern European centres where fewer vegetable oils, more animal fats and a high proportion of margarine were consumed. The consumption of added fats and oils of animal origin was highest in the German EPIC centres, followed by the French. The contribution of added fats and oils to total energy intake ranged from 8% in Norway to 22% in Greece. The results demonstrate a high variation in dietary intake of added fats and oils in EPIC, providing a good opportunity to elucidate the role of dietary fats in cancer aetiology.

Exploring the Potential of Active Learning for Automatic Identification of Marine Oil Spills Using 10-Year (2004–2013 RADARSAT Data

Directory of Open Access Journals (Sweden)

Yongfeng Cao

2017-10-01

Full Text Available This paper intends to find a more cost-effective way for training oil spill classification systems by introducing active learning (AL and exploring its potential, so that satisfying classifiers could be learned with reduced number of labeled samples. The dataset used has 143 oil spills and 124 look-alikes from 198 RADARSAT images covering the east and west coasts of Canada from 2004 to 2013. Six uncertainty-based active sample selecting (ACS methods are designed to choose the most informative samples. A method for reducing information redundancy amongst the selected samples and a method with varying sample preference are considered. Four classifiers (k-nearest neighbor (KNN, support vector machine (SVM, linear discriminant analysis (LDA and decision tree (DT are coupled with ACS methods to explore the interaction and possible preference between classifiers and ACS methods. Three kinds of measures are adopted to highlight different aspect of classification performance of these AL-boosted classifiers. Overall, AL proves its strong potential with 4% to 78% reduction on training samples in different settings. The SVM classifier shows to be the best one for using in the AL frame, with perfect performance evolving curves in different kinds of measures. The exploration and exploitation criterion can further improve the performance of the AL-boosted SVM classifier but not of the other classifiers.

Strategy and perspective for uranium exploration in Egypt

International Nuclear Information System (INIS)

Hassan, M.A.; Salman, A.B.; Assaf, H.S.; Mahdy, M.M.

1995-01-01

Uranium exploration started in Egypt about three decades ago. This was performed by applying integrated airborne and ground radiometric prospecting. The latter was conducted upon selected areas having rather favorable geological criteria. These activities resulted in the discovery of great numbers of radiometric anomalies, with several uranium occurrences in various geologic environments in granitic and sedimentary rocks. Some of these uranium occurrences show good potential for developing into workable uranium deposits. Small-scale exploratory tunnelling and drilling works have been carried out at some of these occurrences. Leaching studies and pilot experiments were carried out on technological samples to evaluate ore's suitability for uranium extraction. However, no assured reserves of uranium have been reached yet. The demands for uranium to satisfy the near future Egyptian nuclear power generation necessitates some development in the national strategy for uranium exploration. This will be achieved through intense programmes for ground geophysics and drilling from surface and underground mining works, in addition to radon emanometry and logging of oil and gas wells. Moreover, non conventional procedures for uranium extraction such as heap-leaching may be followed to exploit small-scale uranium deposits. In this developed strategy, the present uranium occurrences are modellized and categorized following the IAEA classification. The characteristics of the present uranium occurrences will be utilized in prospecting new areas. Subsidiary resources in phosphorites, black sands and rare metal deposits could supply additional quantities of uranium, in addition to thorium and rare earth elements.

Schejbal, C.; Palas, M.

1997-01-01

Reflections on prospective mineral raw materials and materials must rest upon the expected demographic evolution, the evaluation of economic development and the development of manufacturing technologies and materials corresponding to them, trends in the consumption of mineral raw materials and possibilities of securing them. The evaluation of the given factors under conditions of the Czech Republic shows that one of the decisive prerequisites to transforming the Czech economy is to assure the fuel and energy security of the state. In addition to emphasis put on traditional and newly developed technologies of utilization of domestic resources of coal and the development of nuclear power, a diversification of supplies of oil and gas is necessary. Moreover, it is necessary to ensure domestic resources of raw materials to some prospective material areas, or to provide these raw materials by means of imports and/or entrepreneurial activity abroad. As far as raw materials for building and industrial rocks are concerned, it is necessary to support the exploitation and home utilization through laws and suitable economic tools at respecting environmental limitations. With non-traditional prospective raw materials, it will be desirable to promote exploration and mining especially in those cases when a precondition exists for the securing of sufficient reserves or when reserves are already known

Odd man in the oil patch

International Nuclear Information System (INIS)

1994-01-01

Oil companies are taking a serious look at ways to cut exploration costs. Conventional hydrocarbon finding technologies is based on geological and seismic work. Geological data can cost thousands of dollars. A new method being reviewed is that of surface technology that tests soil and rock for signs of hydrocarbons that have migrated from underground pools to or near the surface. The techniques range from testing for the presence of microbes that consume hydrocarbons to radioactive imprints. Members of the oil industry are looking for the competitive edge by reducing exploration costs, using new surface technology to reduce the cost of a barrel of oil, and by increasing the success rate in finding economically feasible hydrocarbons

Calibrating the social value of prospective new goods: The case of hydrogen fuel cell electric Vehicles

Science.gov (United States)

Topel, Robert H.

2018-01-01

Economic studies of the value of a new good or product innovation are typically retrospective: after a new good has been developed and marketed to consumers, data on prices and consumer choices can be used to estimate welfare gains. This paper calibrates the prospective welfare gains in the United States from a nascent vehicle platform, fuel cell electric vehicles (FCVs), that may or may not succeed in competition with existing vehicle platforms. Prospective gains are due to three main sources: (1) possibly reduced carbon emissions compared to existing vehicle alternatives; (2) the monopsony benefit to the U.S. from reducing world oil demand and hence the price of oil; (3) national security benefits due to reduced "oil dependence", mitigating the impact of oil price shocks on national income. I find that the benefits of reduced carbon emissions are likely to be quite small because reduced oil demand in the U.S. as only a small impact on world oil consumption and carbon emissions. Net monopsony benefits to U.S. consumers are much larger.

Concept Study: Exploration and Production in Environmentally Sensitive Arctic Areas

The Alaska North Slope offers one of the best prospects for increasing U.S. domestic oil and gas production. However, this region faces some of the greatest environmental and logistical challenges to oil and gas production in the world. A number of studies have shown that weather patterns in this region are warming, and the number of days the tundra surface is adequately frozen for tundra travel each year has declined. Operators are not allowed to explore in undeveloped areas until the tundra is sufficiently frozen and adequate snow cover is present. Spring breakup then forces rapid evacuation of the area prior to snowmelt. Using the best available methods, exploration in remote arctic areas can take up to three years to identify a commercial discovery, and then years to build the infrastructure to develop and produce. This makes new exploration costly. It also increases the costs of maintaining field infrastructure, pipeline inspections, and environmental restoration efforts. New technologies are needed, or oil and gas resources may never be developed outside limited exploration stepouts from existing infrastructure. Industry has identified certain low-impact technologies suitable for operations, and has made improvements to reduce the footprint and impact on the environment. Additional improvements are needed for exploration and economic field development and end-of-field restoration. One operator-Anadarko Petroleum Corporation-built a prototype platform for drilling wells in the Arctic that is elevated, modular, and mobile. The system was tested while drilling one of the first hydrate exploration wells in Alaska during 2003-2004. This technology was identified as a potentially enabling technology by the ongoing Joint Industry Program (JIP) Environmentally Friendly Drilling (EFD) program. The EFD is headed by Texas A&M University and the Houston Advanced Research Center (HARC), and is co-funded by the National Energy Technology Laboratory (NETL). The EFD

Enterprise Oil gets going

International Nuclear Information System (INIS)

Ross, Priscilla.

1996-01-01

Enterprise Oil is a mature United Kingdom independent oil exploration and production company. In its early years, with the success of the Nelson platform in the North Sea, the company had been well rated by financial analysts in the City of London. Enterprise was floated as an independent company on the International Stock Exchange in London in 1984 having previously been part of the establishment being formed by the Government from the oil and production interests of British Gas on the UK Continental shelf. Relationships with the City suffered, however, as a result of the unsuccessful outcome of moves by the company to take over Lasmo, the only other UK independent oil company of comparable magnitude. Pedestrian financial results and poor exploration results led to Enterprise dividends being stuck in a rut from 1992 onwards. This report, however, shows how that situation is changing so that the company's share price has been reaching new highs. Enterprise has been adding quantitative value to the company through swaps, farm-in deals and licensed acquisitions and now has interests in core income producing areas in the UK, Norway, Denmark and Italy.

The reasons for the recent growth of interest in the use of the Floating Production Storage and Off-loading (FPSO) system in oil field developments are examined. An evaluation of oil field characteristics that influence concept selection is made which shows that the FPSO is a very flexible solution in a wide range of situations. Costs and cost drivers are discussed and some measures of cost effectiveness are proposed to serve as benchmarks for the future. Some technology development challenges are identified. The findings give a high level view of the techno-economic prospects for the FPSO in field developments over the next decade

2012-01-01

Southwest China is one of the important areas where uranium is distributed. After exploration and research of 50 years, the metallogenic conditions for uranium deposits in Southwest China have been studied more deeply. It is found that uranium ore in Southwest China has more complete types, less deposits and more mineral occurrences, and the amount of uranium resources is disproportionate to the area of Southwest China. Researches of years show that Southwest China is characterized by thick crust. thick sedimentary cover, weak crust-mantle interaction, weak deep flu id activity in shallow strata, strong dynamic formation in shallow strata and obvious deep geologic process on block mar- gins. In this paper, the control of deep geologic process and evolution in uranium metallogenesis in Southwest China is studied by employing new theories and thoughts on the fundamental concept that deep geologic process and evolution has important control on super-large scale deposits. The study focuses on the crust-mantle structure and evolution with uranium metallogenesis, structural and magmatic activity and deep fluid activity with uranium metallogenesis, and ore-con- trolling role of penetrating faults on block edges and inside the blocks. To offer theoretic basis for large-scale uranium deposit prospecting in Southwest China, the key research on uranium deposit in Southwest China in future should be on the deep geologic evolution and uranium metallogenesis in Western Qinling Region, the uranium metallogenesis of iron oxide copper gold deposits on Kangdian axis, the uranium metallogenesis in Yunnan-Guizhou contiguous area, the hydrothermal uranium metallogenesis in Eastern Tibet and Western Sichuan, and the connection between sandstone type uranium deposit and magmatic activity. Meanwhile, the above regions are also the key ones for uranium deposit prospecting in Southwest China in a rather long period in future. (authors)

Geological and geomorphological methods for petroleum prospection in the center and west of Cuba

Directory of Open Access Journals (Sweden)

Lourdes Jimenez -de la Fuente

2017-01-01

Full Text Available The provinces of Holguin and Las Tunas have potential gas and oil resources which have not yet been fully discovered. Therefore, an assessment is completed to identify potential areas for hydrocarbon prospection based on the geological and geomorphological methods and supported by geophysical methods. Numerous proofs of the existence of oils in the surface and gas being reported in the petroleum wells are sufficient elements to think that there is an active petroleum system in the area. The analysis is supported by information given on the geological surface maps on scale of 1:100 000, satellite and radar images, information of surface occurrence of hydrocarbons, drilled wells and recent field work and geophysical interpretation results. The main results include the identification of two areas for petroleum exploration: the Maniabón-La Farola is identified as the most potential area and the second one is to the north of the Picanes well 1x. Neotectonic processes are identified to have a strong influence on the first area, which allowed delimitating petroleum system elements through geological and geomorphological methods.

High oil prices: A non-OPEC capacity game

International Nuclear Information System (INIS)

Osmundsen, Petter; Asche, Frank; Misund, Baard; Mohn, Klaus

2005-08-01

The current high oil price is partly due to low investments in the oil industry the last decade. According to economic theory, exploration and development of new oil and gas fields should respond positively to increasing petroleum prices. But since the late 1990s, financial analysts have focused strongly on short-term accounting return measures, like RoACE, for benchmarking and valuation of international oil and gas companies. Consequently, the demand for strict capital discipline among oil and gas companies may have reduced their willingness to invest for future reserves and production growth. Thus, we have experienced an unusual combination of high oil prices and low investment levels in exploration and development. In many ways, the oil companies' focus on RoACE, at the expense of reserve replacement, resembles an implicit co-ordination on low capacity among non-OPEC petroleum producers. This is a partial explanation of the current high oil prices. By examining actual parameters used by the financial markets in pricing of oil companies, we address the issue of whether the low investment outcome could represent a long-term equilibrium. This is hardly likely, as oil companies are made aware that stronger emphasis is put on reserve replacement. (Author)

Special report: EC oil market

International Nuclear Information System (INIS)

Anon.

1992-01-01

A European Commission report on the EC's oil market has conceded that the Community will not meet its official objective of reducing oil's share of energy consumption to 40% by 1995. The paper, a 'Communication' to the European Council entitled ''The Oil Market and the Refining Industry in the Community: Recent Developments and Prospects'' says oil will ''continue to account for a major share - of the order of 45% -of the Community's energy consumption'' up to the year 2000. Nonetheless, the report's authors insist the Commission has proposed ''a number of measures'' which could reduce the potential consumption of fossil fuels and help limit CO2 emissions. The report confirms that though lower in 1990 than 1980 at 530mt, oil demand picked up in the second half of the 1980s, reflecting world trends. Little impression has been made on the proportion of the Community's crude supply that is imported. However, one area where the report did find energy objectives successes was that of diversifying sources of crude oil supply. A major source of concern for the Commission at one stage in the second half of the 1980s was the possibility of massive imports of finished oil products from refineries in the oil producing countries. However, the fact that this threat did not materialise is taken as a vindication of the Commission's assessment in previous analyses that ''an open Community market should be maintained''. (author)

This paper investigates the behavior of the world oil price based on the first-generation target zone model. Using anecdotal data during the period of 1988-1999, we found that OPEC has tried to maintain a weak target zone regime for the oil price. Our econometric tests suggest that the movement of the oil price is not only manipulated by actual and substantial interventions by OPEC but also tempered by market participants' expectations of interventions. As a consequence, the non-linear model based on the target zone theory has very good forecasting ability when the oil price approaches the upper or lower limit of the band. (author)

2016-03-01

Medical learners face many challenging transitions. We prospectively explored students' perceptions of their upcoming transition to clerkship and their future professional selves. In 2013, 160/165 end-of-second-year medical students wrote narrative reflections and 79/165 completed a questionnaire on their perceptions of their upcoming transition to clerkship. Narratives were separately analyzed by four authors and then discussed to identify a final thematic framework using parsimonious category construction. We identified two overarching themes: (1) "Looking back": experiences which had helped students feel prepared for clerkship with subthemes focused on of patient care, shadowing, classroom teaching and the pre-clerkship years as foundational knowledge, (2) "Looking forward": anticipating the clerkship experience and the journey of becoming a physician with subthemes focused on death and dying, hierarchy, work-life balance, interactions with patients, concerns about competency and career choice. Questionnaire data revealed incongruities around expectations of minimal exposure to death and dying, little need for independent study and limited direct patient responsibility. We confirmed that internal transformations are happening in contemplative time even before clerkship. By prospectively exploring pre-clerkship students' perceptions of the transition to clerkship training we identified expectations and misconceptions that could be addressed with future curricular interventions. While students are aware of and anticipating their learning needs it is not as clear that they realise how much their future learning will depend on their own inner resources. We suggest that more attention be paid to professional identity formation and the development of the physician as a person during these critical transitions.

East Africa, an oil geopolitics at high risk

Auge, Benjamin

2012-11-01

As the Sub-Saharan African oil production has been concentrated in the Guinea Gulf countries since the 1950's, as this region remains the main African oil producer (Maghreb excluded), and as new discoveries has been made in Uganda in 2006 and exploration has been extended to neighbouring countries (Ethiopia, Kenya, Tanzania, Mozambique), this report first questions the situation of the exploration of the Albert Lake by proposing an overview of intervening actors, by commenting the political use of the debate about oil, by commenting the situation on the Congolese side of the lake, and by commenting how the lake is shared between Uganda and the Republic of Congo. In the next part, the author discusses the use and future of the Ugandan oil by outlining the role of the Essar company in the regional refining, and by evoking projects of regional pipelines. The last part addresses the status of exploration in other East African countries (Kenya, Ethiopia, South Sudan, Tanzania, Mozambique)

The ACEGES laboratory for energy policy: Exploring the production of crude oil

Voudouris, Vlasios; Stasinopoulos, Dimitrios; Rigby, Robert; Di Maio, Carlo

2011-01-01

An agent-based computational laboratory for exploratory energy policy by means of controlled computational experiments is proposed. It is termed the ACEGES (agent-based computational economics of the global energy system). In particular, it is shown how agent-based modelling and simulation can be applied to understand better the challenging outlook for oil production by accounting for uncertainties in resource estimates, demand growth, production growth and peak/decline point. The approach emphasises the idea that the oil system is better modelled not as black-box abode of 'the invisible hand' but as a complex system whose macroscopic explananda emerges from the interactions of its constituent components. Given the estimated volumes of oil originally present before any extraction, simulations show that on average the world peak of crude oil production may happen in the broad vicinity of the time region between 2008 and 2027. Using the proposed petroleum market diversity, the market diversity weakness rapidly towards the peak year. - Highlights: → Development of oil scenarios using computational experiments. → Support of energy policy using agent-based modelling and simulation. → Demonstration of the agent-based computational economics of the global energy system (ACEGES) policy-support tool. → Energy policy by means of evidence-based forward-looking probabilistic forecasts.

A grave problem of modern oil refining industry is continuous deterioration of the produced oil quality, on the one hand, and increase in the demand for motor fuels, on the other hand. This necessitates processing of heavy oil feedstock with high contents of sulfur, nitrogen and metals and the atmospheric residue. This feedstock is converted to light oil products via hydrogenation processes catalyzed by transition metal compounds, first of all, cobalt- or nickel-promoted molybdenum and tungsten compounds. The processing involves desulfurization, denitrogenation and demetallization reactions as well as reactions converting heavy hydrocarbons to lighter fuel components. The review discusses the mechanisms of reactions involved in the heavy feedstock hydroprocessing, the presumed structure and state of the catalytically active components and methods for the formation of supports with the desired texture. Practically used and prospective approaches to catalytic upgrading of heavy oil feedstock as well as examples of industrial processing of bitumen and vacuum residues in the presence of catalysts are briefly discussed. The bibliography includes 140 references

India expanding oil/gas E and D, infrastructure

International Nuclear Information System (INIS)

Anon.

1991-01-01

This paper reports that India continues to press oil and gas exploration and development and expansion of its petroleum sector infrastructure. One of the key moves is the government's decision to stage a fourth exploration bidding round, its most ambitious to date and one expected to elicit enthusiasm from international oil companies. At the same time, state oil companies Oil and Natural Gas Commission and Oil India Ltd. plan to maintain strong domestic E and D programs. ONGC is seeking more revenue to sustain India's ambitious oil and gas upstream plans. The state company has asked the government for a 50% hike in the price of domestic crude. The government currently pays ONGC and OIL only about $8.84/bbl, a price fixed in 1981. A jump of 50% in the domestic crude price would net ONGC another $1 billion/year in revenues, ONGC Chairman S.L. Khosla the. The government and other state companies also continue efforts to expand gas utilization and markets and match refining plans with market needs

Thermal maturity history and implications for hydrocarbon exploration in the Catatumbo basin, Colombia

International Nuclear Information System (INIS)

Rangel, Antonio; Hernandez, Roberto

2007-01-01

A thermal model integrated with oil and gas geochemical study has been constructed for the Catatumbo basin, Colombia for provides petroleum system data for hydrocarbon exploration. The calibration of the thermal model with maturity data took into account a changing heat flow scheme which included a thermal increase towards the end of the Jurassic and another one in the early Eocene, associated with rifting events. Locally, active/generating source rocks are within the synclines axes. The hydrocarbon expulsion time for Cretaceous source rocks (Capacho and La Luna formations) started in the upper Paleocene-Eocene, while for the los Cuervos Formation the generation and expulsion started of 1 0 my. The petroleum expelled during the Paleocene-Miocene, were likely accumulated in structures formed since the end of the cretaceous, while the younger structures that resulted from the Andean orogen were charged by remigration from the older structures and additionally with the youngest lately generated hydrocarbons. The accumulations of hydrocarbons are mainly the result of generation and migration locally within the basin. The Catatumbo Basin contains thermogenic wet gases with different degrees of thermal maturity which varies from around 1,0 for 2,5 equivalent Ro. The highest degree of thermal evolution according to maturity indicators and thermal modeling is in the southern area, which is prospective for wet gas. The central and northern area appears more prospective for oil with minor amounts of gas

China's oil use, 1990-2008

International Nuclear Information System (INIS)

Leung, Guy C.K.

2010-01-01

Over the past two decades, China's oil demand has risen steeply. In 1990, it was only about 25% higher than that of 1978, the year economic reform was introduced. By 2008, it had reached 396.0 million tons, roughly four times the 1978 level, making China the second largest oil user worldwide. The country became a net oil importer in 1993, and between 1993 and 2008, its net import dependency - a yardstick for energy security - soared from 7.5% to 50.0%. China's increased demand for oil has made the country a global energy player of critical importance. Although the literature on the global implications of China's oil use has proliferated, relatively few studies have attempted to examine ''how China uses oil.'' Hence, this study covers every oil-consuming facility and sector in China, exploring the patterns of, and factors involved in, oil demand by power plants, oil refineries, heat plants and, gas-works, and industrial, transport, agricultural, household and commercial sectors. It concludes that in virtually all sectors in China, oil demand will grow, with transport and industry leading the way. (author)

Yemen: a new oil frontier or a flashpoint?

International Nuclear Information System (INIS)

Salameh, M.G.

1994-01-01

Recent oil discoveries in the newly merged country of Yemen (previously North and South Yemen) should have brought economic security to a country struggling to introduce multi-party democracy. International oil companies such as BP, Elf and Total, while keen to invest in this exciting new prospect for petroleum production, are, however, wary due to border disputes, possibly leading to military conflict between Yemen and Saudi Arabia. The oil finds have been in the disputed Hadramaut region and desert areas of the Southern Arabian basin where borders have never been defined. Early settlement of this dispute could benefit both countries economically and in terms of industrial development. (UK)

Venezuela opens up to explorers

Kielmas, M.

1995-01-01

The opening of Venezuela's first exploration bidding round since oil nationalisation in 1976 was a turning-point in the country's energy policy. The state oil company, Petroleos de Venezuela (PdVSA), has said that the bidding round could generate investment of some $11 billion eventually in development investment and that over the next 10 years, nearly 20 percent of a planned $55 billion, 10-year state oil company investment programme could also come from foreign or private sector oil investment. Should this optimistic prediction materialise, Venezuela, whose 2.75 million b/d oil production in October was some 400,000 b/d over its Opec quota, will remain both the dominant oil producer in Latin America and the top-ranking oil exporter to the US market. In May this year, Venezuelan oil exports topped 1.43 million b/d, or some 16.8 percent of the US market, compared with Saudi Arabia's 15.7 percent. (author)

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

Bravo, E.

1998-01-01

The sea provides a vast array of natural resources for thousands of local communities in the tropics. But the presence of the oil industry has significant social and environmental impacts, both from accidents and from routine activities like seismic exploration, drilling and the generation of polluting wastes. When accidents occur, sessile life (species attached to surface such as rocks or the seabed) is the first to be affected; its mortality increases as oil accumulates, although certain organisms, like gastropods, tolerate it better

Deep Drilling Into the Chicxulub Impact Crater: Pemex Oil Exploration Boreholes Revisited

Science.gov (United States)

Fucugauchi, J. U.; Perez-Cruz, L.

2007-05-01

The Chicxulub structure was recognized in the 1940´s from gravity anomalies in oil exploration surveys by Pemex. Geophysical anomalies occur over the carbonate platform in NW Yucatan, where density and magnetic susceptibility contrasts with the carbonates suggested a buried igneous complex or basement uplift. The exploration program developed afterwards included several boreholes, starting with the Chicxulub-1 in 1952 and eventually comprising eight deep boreholes completed through the 1970s. The investigations showing Chicxulub as a large impact crater formed at the K/T boundary have relayed on the Pemex decades-long exploration program. Despite frequent reference to Pemex information, original data have not been openly available for detailed evaluation and incorporation with results from recent efforts. Logging data and core samples remain to be analyzed, reevaluated and integrated in the context of recent marine, aerial and terrestrial geophysical surveys and the drilling/coring projects of UNAM and ICDP. In this presentation we discuss the paleontological data, stratigraphic columns and geophysical logs for the Chicxulub-1 (1582m), Sacapuc-1 (1530m), Yucatan-6 (1631m) and Ticul-1 (3575m) boreholes. These boreholes remain the deepest ones drilled in Chicxulub and the only ones providing samples of the melt-rich breccias and melt sheet. Other boreholes include the Y1 (3221m), Y2 (3474m), Y4 (2398m) and Y5A (3003m), which give information on pre-impact stratigraphy and crystalline basement. We concentrate on log and microfossil data, stratigraphic columns, lateral correlation, integration with UNAM and ICDP borehole data, and analyses of sections of melt, impact breccias and basal Paleocene carbonates. Current plans for deep drilling in Chicxulub crater focus in the peak ring zone and central sector, with proposed marine and on-land boreholes to the IODP and ICDP programs. Future ICDP borehole will be located close to Chicxulub-1 and Sacapuc-1, which intersected

Hubbert's Oil Peak Revisited by a Simulation Model

International Nuclear Information System (INIS)

Giraud, P.N.; Sutter, A.; Denis, T.; Leonard, C.

2010-01-01

As conventional oil reserves are declining, the debate on the oil production peak has become a burning issue. An increasing number of papers refer to Hubbert's peak oil theory to forecast the date of the production peak, both at regional and world levels. However, in our views, this theory lacks micro-economic foundations. Notably, it does not assume that exploration and production decisions in the oil industry depend on market prices. In an attempt to overcome these shortcomings, we have built an adaptative model, accounting for the behavior of one agent, standing for the competitive exploration-production industry, subjected to incomplete but improving information on the remaining reserves. Our work yields challenging results on the reasons for an Hubbert type peak oil, lying mainly 'above the ground', both at regional and world levels, and on the shape of the production and marginal cost trajectories.

From agro-industrial wastes to single cell oils: a step towards prospective biorefinery.

Science.gov (United States)

Diwan, Batul; Parkhey, Piyush; Gupta, Pratima

2018-04-23

The reserves of fossil-based fuels, which currently seem sufficient to meet the global demands, is inevitably on the verge of exhaustion. Contemporary raw material for alternate fuel like biodiesel is usually edible plant commodity oils, whose increasing public consumption rate raises the need of finding a non-edible and fungible alternate oil source. In this quest, single cell oils (SCO) from oleaginous yeasts and fungi can provide a sustainable alternate of not only functional but also valuable (polyunsaturated fatty acids (PUFA)-rich) lipids. Researches are been increasingly driven towards increasing the SCO yield in order to realize its commercial importance. However, bulk requirement of expensive synthetic carbon substrate, which inflates the overall SCO production cost, is the major limitation towards complete acceptance of this technology. Even though substrate cost minimization could make the SCO production profitable is uncertain, it is still essential to identify suitable cheap and abundant substrates in an attempt to potentially reduce the overall process economy. One of the most sought-after in-expensive carbon reservoirs, agro-industrial wastes, can be an attractive replacement to expensive synthetic carbon substrates in this regard. The present review assess these possibilities referring to the current experimental investigations on oleaginous yeasts, and fungi reported for conversion of agro-industrial feedstocks into triacylglycerols (TAGs) and PUFA-rich lipids. Multiple associated factors regulating lipid accumulation utilizing such substrates and impeding challenges has been analyzed. The review infers that production of bulk oil in combination to high-value fatty acids, co-production strategies for SCO and different microbial metabolites, and reutilization and value addition to spent wastes could possibly leverage the high operating costs and help in commencing a successful biorefinery. Rigorous research is nevertheless required whether it is

Prospect of coal liquefaction in Indonesia

1997-01-01

With the current known oil reserves of about 11 billion barrel and annual production of approximately 500 million barrel, the country's oil reserves will be depleted by 2010, and Indonesia would have become net oil importer if no major oil fields be found somewhere in the archipelago. Under such circumstances the development of new sources of liquid fuel becomes a must, and coal liquefaction can be one possible solution for the future energy problem in Indonesia, particularly in the transportation sector due to the availability of coal in huge amount. This paper present the prospect of coal liquefaction in Indonesia and look at the possibility of integrating the process with HTR as a heat supplier. Evaluation of liquidability of several low grade Indonesian coals will also be presented. Coal from South Banko-Tanjung Enim is found to be one of the most suitable coal for liquefaction. Several studies show that an advanced coal liquefaction technology recently developed has the potential to reduce not only the environmental impact but also the production cost. The price of oil produced in the year 2000 is expected to reach US $ 17.5 ∼ 19.2/barrel and this will compete with the current oil price. Not much conclusion can be drawn from the idea of integrating HTR with coal liquefaction plant due to limited information available. (author). 7 figs, 3 tabs

The modifications that were introduced in the system of oil trade and other factors that influence directly in these processes (environmental license, law of bonuses and the expropriation), although they stopped the signature of new contracts, they prepared the land for what will be the exploration and production of hydrocarbons in the national territory starting from the year 2000. Ecopetrol and their associate advanced an intense campaign to discover additional reserves of hydrocarbons, inside which are regional studies in most of the 18 basins in that the country is divided. It has allowed it to Ecopetrol to define a total of 83 prospects, so much for the direct operation as the associate, with a potential of reserves of approximately 11.500 million barrels of equivalent petroleum. The paper treats aspects on reserves, seismic activity, perforation and production among others

Oil and gas fiscal regime review

International Nuclear Information System (INIS)

1993-04-01

Poor levels of oil and gas industry profitability, declining activity, and increasing provincial budgetary pressures led to formation of a joint government/industry committee to review fiscal systems in the oil and gas industry and identify areas for potential change. An overview is presented of the development of oil and gas resources in Saskatchewan, showing that reserves and production peaked in 1966. Although reserves and production declined steadily until the early 1980s, some growth has occurred in the past decade, largely due to the influence of horizontal drilling. The province's oil and gas royalty structure is then summarized, giving the classes of oil and gas production and the royalty applicable to each class, as well as incentives available to encourage exploration and development activity. Opportunities for increased exploration and development are identified in two categories (existing wells and new wells) and impacts of possible changes in the existing royalty and incentive regime are discussed. Recommendations are provided to promote new capital investment in the industry and to extend the economic life of existing wells which are at or near the point of abandonment or suspension. 40 figs., 16 tabs

Full Text Available Physical, mechanical, and chemical properties of Shorea robusta seed with wing, seed without wing, and kernel were investigated in the present work. The physico-chemical composition of sal oil was also analyzed. The physico-mechanical properties and proximate composition of seed with wing, seed without wing, and kernel at three moisture contents of 9.50% (w.b, 9.54% (w.b, and 12.14% (w.b, respectively, were studied. The results show that the moisture content of the kernel was highest as compared to seed with wing and seed without wing. The sphericity of the kernel was closer to that of a sphere as compared to seed with wing and seed without wing. The hardness of the seed with wing (32.32, N/mm and seed without wing (42.49, N/mm was lower than the kernels (72.14, N/mm. The proximate composition such as moisture, protein, carbohydrates, oil, crude fiber, and ash content were also determined. The kernel (30.20%, w/w contains higher oil percentage as compared to seed with wing and seed without wing. The scientific data from this work are important for designing of equipment and processes for post-harvest value addition of sal seeds.

Oil Transport Networks in Europe

Full Text Available The author examines the problems and prospects of crude oil and petroleum products transportation market on the European continent. Particular attention is paid to the possibilities of the planned pipeline routes and new supplies of oil and petroleum products. European Union countries have large reserves of hydrocarbons, but it is not enough to fully satisfy domestic consumption. Improved pipeline infrastructure both within the EU and oil pipelines from other countries is an important economic and social factor. Recent developments of this year especially emphasize the importance of strengthening the energy security in the foreign policy of the state. For transporting fuel energy in Europe used the following types of transport: marine (sea and river, truck, railway, and pipeline. It seems necessary to mention the fact that the role of pipeline transport is particularly high in the oil and gas industry. Pipeline transport has an important impact on the formation and developmen t of the fuel and energy complex of the state, as well as regions, as its integral part. An effective system of crude oil and petroleum products pipelines is an important tool for the implementation of public policies, policies at the EU level, allowing the country to regulate the supply of crude oil and petroleum products to the overseas and domestic markets.

International petroleum licensing, exploration activity and fiscal terms

International Nuclear Information System (INIS)

Hodgshon, S.

1994-01-01

Although there is no decline in current international petroleum licensing activity, attention is drawn to the fact that it is concentrated in certain countries, many of them amongst the less geologically prospective. Among the factors other then geological prospectivity which promote a successful licensing and exploration environment, the most important is the fiscal terms offered. While countries which are highly prospective geologically may stiffen terms and still attract exploration companies because they feel they can make major discoveries, any decline in prospectivity needs to be accompanied by a matching change in fiscal terms to maintain interest. Less prospective countries which, hitherto, have created favourable investment conditions may however find that further declines cannot be reversed by attractive fiscal terms. (7 figures, 3 tables).

Palm oil is a cheap and versatile edible oil in widespread use as a food ingredient that has been linked to negative health and environmental outcomes. The current study aimed to understand the prospects for future health-focused policy development to limit food use of palm oil and promote a greater diversity of oils in Thailand's food system. Eighteen semi-structured interviews were conducted with a range of stakeholders. The interviews probed views on the economic, health and environmental dimensions of the issue, the prospects for health-focused policy development and the policy development process. Transcripts were analysed using a health policy analytical framework. Thailand. Stakeholders from a range of ministries, regulatory agencies, the private sector, non-governmental organizations and academia. There are several impediments to the emergence of strong regulation, including the primacy of economic considerations in setting policy, doubt and misperception about health implications and a complex regulatory environment with little space for health-related considerations. At the same time, some sections of the food industry producing food for domestic consumption are substituting palm with other oils on the basis of consumer health perceptions. Strong regulation to curb the growth of palm oil is unlikely to emerge soon. However, a long-term strategy can be envisaged that relies on greater policy support for other indigenous oils, strategic rebalancing towards the use of palm oil for biofuels and oleochemicals, and harnessing Thailand's food technology capabilities to promote substitution in food production in favour of oils with healthier fatty acid composition.

Preoperative imaging studies localize insulinomas in less than 50% of patients. Arteriography with calcium stimulation and venous sampling (ASVS) regionalizes greater than 90% of insulinomas but requires specialized expertise and an invasive procedure. This prospective study evaluated laparoscopic exploration with IOUS compared with the other localization procedures in patients with a sporadic insulinoma. Between March 2001 and October 2004, 14 patients (7 women and 7 men; mean age, 53) with an insulinoma were enrolled in an IRB-approved protocol. Computed tomography, magnetic resonance imaging, ultrasound scan, and arteriography with calcium stimulation and venous sampling were performed preoperatively. A surgeon, blinded to the results of the localizing studies, performed a laparoscopic exploration with intraoperative ultrasound (IOUS). At the completion of the exploration, the success of laparoscopy for localization was scored, and the tumor was resected. Twelve of 14 tumors were localized successfully before laparoscopy (noninvasive, 7 of 14; invasive, 11 of 14). Laparoscopic IOUS localized successfully 12 of 14 tumors. All lesions were resected, and all patients were cured (median follow-up, 36 months). Laparoscopic IOUS identified 86% of tumors. The authors consider laparoscopic IOUS to be equivalent to ASVS in localizing insulinomas. Further study is therefore warranted to determine the role of laparoscopy with IOUS in the localization and treatment algorithm for patients with sporadic insulinoma.

The greater Moluccas are bounded by the Pacific and Indian oceanic plates and the greater Australian and Sunda continental crustal plates or shelves.The effect of their opposing movement is a giant counterclockwise sworl. The island arcs within this pattern are parts of subduction zones between the opposing plates. The Sorong transform left lateral fault resulted from these forces and offset remnants of the W. Irian shelf terrane at least 700 km westerly to the Sula islands. Sedimentary rocks of pre-Pliocene to Permian age occur notably in Timor and the Sula islands. In most localities they are deformed and indurated to the extent of making them economic basement. Plio-Pleistocene linear sedimentary basins follow the ''S'' trend and reach a maximum of 3,000 m in thickness in NE. Ceram and Timor. Rocks include deep water claystones, shelf and lagoonal clays, bar and beach sands, and barrier coral reefs. Oil seeps occur on Ceram, Timor, and Buton (asphalt) mostly from Plio-Pleistocene rocks. Oil is produced at Bula, Ceram, from Pleistocene bar and shoreline sands in stratigraphic traps. A recent development at Bula has established prolific production from an extremely permeable Pleistocene reef.

Oil: Economics and politics

International Nuclear Information System (INIS)

Ayoub, A.

1994-01-01

A review is presented of the evolution of the international petroleum sector since 1973 with a special emphasis on the interdependence between the economic and political factors that influence it. Two issues are focused on: the effects of the nationalization of oil companies on the sharing of oil rents and on changes in the structure of the oil market; and the determination of oil prices. Definitions are presented of oil rents, and the reasons for OPEC nationalization of oil companies are explored. The effects of nationalization on market structures, expansion of free markets, and vertical integration are discussed. The existence of an oil price floor and the reasons for such a floor are examined. It is shown that nationalization induced an internalization of rents by the producing countries, leading to the emergence of a differential rent supported by the politics of the industrialized countries. Nationalization led to the breakup of systems of vertical and horizontal integration, with replacement by a new dual structure with OPEC controlling the upstream activities of the oil sector and oil companies controlling the downstream ones. Prices move between a floor price set by the costs of substitute deposits in the U.S., while the determination of ceiling levels by OPEC rests on successive fragile compromises. Overall oil is still a strategic product, despite the existence of spot markets, forward trading options, etc. 29 refs

GWPC, DOGGR, and other state agencies propose to build eBusiness applications based on a .NET front-end user interface for the DOE's Energy 100 Award-winning Risk Based Data Management System (RBDMS) data source and XML Web services. This project will slash the costs of regulatory compliance by automating routine regulatory reporting and permit notice review and by making it easier to exchange data with the oil and gas industry--especially small, independent operators. Such operators, who often do not have sophisticated in-house databases, will be able to use a subset of the same RBDMS tools available to the agencies on the desktop to file permit notices and production reports online. Once the data passes automated quality control checks, the application will upload the data into the agency's RBDMS data source. The operators also will have access to state agency datasets to focus exploration efforts and to perform production forecasting, economic evaluations, and risk assessments. With the ability to identify economically feasible oil and gas prospects, including unconventional plays, over the Internet, operators will minimize travel and other costs. Because GWPC will coordinate these data sharing efforts with the Bureau of Land Management (BLM), this project will improve access to public lands and make strides towards reducing the duplicative reporting to which industry is now subject for leases that cross jurisdictions. The resulting regulatory streamlining and improved access to agency data will make more domestic oil and gas available to the American public while continuing to safeguard environmental assets.

From the viewpoint of waste-to-energy, waste cooking oil is one of the attractive and available recycled feedstocks, apart from agricultural residues. The generation of energy from waste cooking oil is considered as an effective technique for waste management, as well as a beneficial form of energy recovery. Two alternative systems and a conventional system of waste cooking oil collection and conversion are evaluated by the cost benefit analysis in order to find a suitable method for waste-to-energy conversion. The results show that the collection of waste cooking oil with waste lubricating oil (System II) a useful alternative to the management of waste cooking oil (B/C > 1). The total heat produced by the combustion of pyrolytic oil at maximum and minimum conversion rates is also determined. The separate collection of waste cooking oil, subjected to chemical pre-treatment prior to introduction in a pyrolysis reactor (System III), is considered an undesirable option (B/C < 1) due to the cost of the chemicals involved. Although the exclusion of chemical pre-treatment makes System III a desirable option, the total amount of heat of combustion generated is less. The increased electricity cost required for the process has no effect on the benefit-cost ratio of System II. However, System III, excluding chemical pre-treatment, becomes an unprofitable alternative when the electricity cost reaches 100% of the fixed capital cost at the minimum conversion rate.

The surge in the oil price has raised questions about the magnitude of global reserves of oil. According to some analysts, the current high oil prices indicate a looming decline in the global production of oil. Others believe, however, that the increased level of the oil price encourages exploration and production activities, bringing the oil price to a lower equilibrium level in the near future. In this paper, we assess the impact of the unit profit (depending on the oil price) as well as fiscal facilities on the level of exploration and development drillings in the Dutch Continental Shelf. We conducted an econometric analysis of exploration and development drillings in the Dutch Continental Shelf over the period 1981-2003. Except a few fiscal changes, the regulatory framework for offshore activities in the Netherlands, the so-called 'small fields policy' was unchanged in this period. We find that the expected unit profit based on a moving average of the oil price significantly explains the level of both exploration and development drillings. In addition, the analysis suggests that fiscal facilities have only a temporary effect on exploration activities but are more important for development activities. We conclude that the oil price is a major economic incentive for activities of the mining industry

It is expected that crude oil production in China will maintain its current level until 2020. Driven by higher living standards and the rapid development of energy intensive industries, China's oil demand will increase rapidly and might lead to heavier import dependency. Three cases of demand forecasts are presented, but for the sake of sustainable economic and social development, neither the high nor the middle case is favourable for China. Thus, China must seek a path of oil saving economic development, and limit oil consumption to no more than 350MT in 2010 and 450MT in 2020. Meanwhile, in order to secure the oil supply, the following strategies should be adopted: save oil and develop alternative energies; stabilise domestic oil production and to diversify oil imports and overseas oil exploration and development; accelerate the gas industry and introduce strategic petroleum reserves.

heating value and high content of oxygen, which makes it unsuited for direct utilization in engines. One prospective technology for upgrading of bio-oil is steam reforming (SR), which can be used to produce H2 for upgrading of bio-oil through hydrodeoxygenation or synthesis gas for processes like......-oil. There are two main pathways to minimize carbon deposition in steam reforming; either through optimization of catalyst formulation or through changes to the process parameters, like changes in temperature, steam to carbon ratio (S/C), or adding O2 or H2 to the feed. In this thesis both pathways have been...

Role of oil imports in economic development

This paper reports that energy has a vital role to play in a developing economy. The process of industrialization calls for continuous increase in energy use. In general, the greater the use of energy, the higher the economy is placed in the order of developed countries. Countries with high per-capita income have a high consumption level of energy too. On a per-capita basis, energy consumed in U.S.A. is 51.7 barrels of oil equivalent per year while in India, it is 0.9 barrels of oil equivalent only. Therefore, energy consumption, industrial development and economic growth are interlinked. Energy became a significant part in the process of development. In the case of developing countries, any change in the price of oil has a negative effect on economic growth. It was stated in one of the Oil and Natural Gas Commission reports that a fivefold increase in the international price of oil, in real terms, over the past 15 years has had profound effects on balance of payments and growth prospects in developing countries

Oil investment in Latin America

Kielmas, M.

1994-01-01

In the early 1990s Latin America became a favoured target for foreign investors as one of the side-effects of the collapse of communism in Eastern Europe and the Soviet Union. The reason is linked to macroeconomic reforms in Latin America and the failure of equivalent reforms in the former communist countries. Latin American state-owned-oil companies have been welcomed as borrowers on the international financial markets. Simultaneously private sector investment in the oil industry has increased. This chapter examines nationalisation and the state oil companies, the financing of the state sector, privatisation, the boosting of oil exploration and security issues. The sustainability of the economic reforms in the region is discussed. (UK)

Non-destructive methods of detecting oil spills are reviewed. Geobotanical and geophysical electrical methods have had a long tradition in geological prospecting; at the present time they can be applied, in principle, to search for and to delineate oil spills. Photography is in its early stage of research in order to establish its practical use in detecting oil products. While substantial problems are not to be expected when applying infrared color photography do detect gaseous hydrocarbons, the problem of the feasibility of photoindications of pollutions caused by liquid hydrocarbons remains unsolved. High-quality spectrophotometers, spectroradiometers and infrared thermal scanners are too expensive to be available at each of the prospecting organizations. It seems to be more advantageous to equip one laboratory with peak instrumentation allowing to accomplish the basic spectrometric and thermometric measurements. Of the techniques not tested so far, radar, contactless thermometry or microseismics can be of importance for locating the presence of oil under ground. The application of nonphotographic remote sensing from satellites does not seem probable so far.

A green prospective based on the reuse of waste materials such as almond shells, orange peel and used cooking oil to manufacture soap is presented. In Portugal, thousands of tons of waste are generated from used cooking oil and production of nut shells' residues is growing every year. In addition, the high consumption of citrus fruits, oranges in particular, generates large amounts of citrus peel. Therefore, it is necessary to diversify reuse mechanisms of these wastes, in order to make them back into raw materials. Complying with this trend, this work was carried out by processing and grinding almond shells, treating used oil, processing orange peels and extracting limonene, formulating and producing soap, and performing an acceptance study of the final product. Results validated a high potential of the idea in the field of environmental education, so it can be replicated in practical classes. It can also be useful for waste management, and it can support the development of community projects on an ecological approach. Copyright © 2017 Elsevier Ltd. All rights reserved.

Prospective developments, production and revenues from the UKCS 1995-2000: a financial and regional simulation

This paper examines the development and production prospects for oil and gas from the UKCS in the period 1995-2000 using a financial simulation model applied to a large database. Emphasis is given to the prospects in the different regions of the UKCs. Oil production is likely to peak in the period and decline slowly thereafter. Gas production will increase substantially throughout the period to 2000. The relative importance of the central North Sea as a producing region will increase substantially in the period, while the northern North Sea will show a decrease. Investment patterns will reflect these trends. Revenues from the UKCS will continue to make a substantial contribution to the economy. The UK should be more than self sufficient in oil and to beyond 2000. Potential gas production should also exceed UK gas demand well beyond 2000. (author)

Strategies of African national oil companies

The study and comparison of different National Oil Companies (NOC) help understanding the political history of Algeria, Nigeria and Angola. The NOC's role and activities depend on several economic and political aspects. For example, Angolan Sonangol has been the coffer for the Popular Movement of Liberation of Angola (MPLA) party to fund its struggle against the National Union for the Independence of Angola (UNITA) party during civil war. Hence the key role played by this NOC in the past and its continuing key influence today. In Nigeria, The Nigerian National Petroleum Corporation (NNPC) became more and more bureaucratic, its efficiency is questionable as the company became the epicentre of the corruption in the country (several cases regarding billions of dollars have emerged recently). By contrast, Algeria's Sonatrach has accumulated a real know how in exploring and producing oil and gas but several successive laws discouraged private sector investments. Algeria doesn't have the necessary technology for unconventional oil and gas exploration (notably shale oil and gas), neither the funds to develop all its huge geological potential

Adelman, M.A.

1993-01-01

A forecast is presented of the likely trends in world oil prices over the short to medium term. A historical background is presented of the OPEC cartel and its role in influencing oil prices. The incentives and disincentives for OPEC to raise prices, and the tensions within the cartel are explored. Slower demand growth and the expansion of natural gas are expected to put downward pressure on oil prices, which are currently artificially high. The impacts of high taxes on development and exploration are examined, and it is shown that state ownership poses an obstacle to improved performance. Threats of price decline are expected to continue to lead to threats of hasty, or even violent action on the part of OPEC members, as happened in 1990. Privatization and tax codes designed to skim rent are positive trends

This paper reports that Alcorn International Inc., Houston, is producing about 16,500 b/d of oil from West Linapacan A field in the South China Sea off the Philippines. The field's current production alone is more than fivefold the Philippines' total average oil flow of 3,000 b/d in 1991. It's part of a string of oil and gas strikes off Palawan Island that has made the region one of the hottest exploration/development plays in the Asia-Pacific theater

Histograms showing variations in oil yield, water yield, and specific gravity of oil from Fischer assay analyses of oil-shale drill cores and cuttings from the Piceance Basin, northwestern Colorado

Recent studies indicate that the Piceance Basin in northwestern Colorado contains over 1.5 trillion barrels of oil in place, making the basin the largest known oil-shale deposit in the world. Previously published histograms display oil-yield variations with depth and widely correlate rich and lean oil-shale beds and zones throughout the basin. Histograms in this report display oil-yield data plotted alongside either water-yield or oil specific-gravity data. Fischer assay analyses of core and cutting samples collected from exploration drill holes penetrating the Eocene Green River Formation in the Piceance Basin can aid in determining the origins of those deposits, as well as estimating the amount of organic matter, halite, nahcolite, and water-bearing minerals. This report focuses only on the oil yield plotted against water yield and oil specific gravity.
