Effect of zero discharge permits on oil and gas operations

International Nuclear Information System (INIS)

Higdon, G.D.

1994-01-01

This paper examines one of the more prominent effects of the Clean Water Act (CWA) upon oil and gas operations. To that end, the paper begins with a general discussion of the regulatory background and permitting framework which serves as the foundation for water pollution control. From this discussion, the paper will then move into a discussion of particular permit provisions which govern the discharge of wastes generated from oil and gas operations. Upon discussing these provisions, the paper will then discuss potential enforcement options available to the Environmental Protection Agency (EPA) to address violations of the regulations and permits it has issued to implement the CWA. In that regard, the paper will also discuss some recent enforcement theories advocated by the EPA which may have significant impacts upon oil and gas operators and the way in which they conduct their operations. In light of some of these recent enforcement activities, the paper will close with a discussion of the implications of the theories of liability espoused by EPA and steps which oil and gas operators may taking in response to the positions assumed by EPA

The oil and gas operator as fiduciary

Evans, Edward.

1992-01-01

What, if any, fiduciary duties are owed by those who direct oil and gas operations to their co-venturers? The question is a complex one that has led to much controversy among industry participants, lawyers, academics and judges. The law dealing with fiduciary duties has been constantly evolving in Canada as in other countries and has yet to reach its definitive form. The principles which underlie when a fiduciary relationship will exist and the scope of the duties that will be imposed on the fiduciary in a given relationship are elusive. Yet, while the courts in Canada have raised what amounts to a presumption against the existence of a fiduciary relationship in arm's length commercial transactions, it is clear that the presumption is rebuttable and may be disregarded in light of the facts of a particular case. Certain observations may be made about the potential fiduciary obligations of an operator of oil and gas properties from the decided cases in the oil and gas area and the trends in other areas of the law as they relate to fiduciaries. Such operators have routinely had imposed on them a duty of good faith or have been classified as in a fiduciary relationship with the non-operators, at least with respect to the management, administration and marketing of the product and ultimately the distribution of the revenues. These observations may provide useful guidelines to those companies who are operators or joint operators in a complex industry in which the same organisations may find themselves simultaneously to be conventurers in relation to one piece of property and intense competitors with respect to another.

2004-07-01

Every day, oil companies around the world face real-life field development and management problems like the ones described above. Making timely and well-informed field development decisions are among the most important decisions the management of any oil company can make. The field development phase of the oil and gas life cycle extends from the discovery of a hydrocarbon deposit through initial production. It also includes revitalization of mature and marginal fields. Field development projects require the greatest level of cross-disciplinary integration and the largest investment decisions in the entire oil field life cycle. The ultimate economic success or failure of most fields is set by the quality of decisions made during field development. Oil companies take many different approaches to field development based on unique business drivers, their asset portfolio mix and risk tolerance, access to data and experienced manpower, adoption of technology, availability of capital, ownership, management style and so on. This paper focuses on understanding and addressing the particular field development challenges facing NOCs today. (author)

America's abundant unconventional oil and natural gas (UOG) resources are critical components of our nation's energy portfolio. These resources need to be prudently developed to derive maximum benefits. In spite of the long history of hydraulic fracturing, the optimal number of fracturing stages during multi-stage fracture stimulation in horizontal wells is not known. In addition, there is the dire need of a comprehensive understanding of ways to improve the recovery of shale gas with little or no impacts on the environment. Research that seeks to expand our view of effective and environmentally sustainable ways to develop our nation's oil and natural gas resources can be done in the laboratory or at a computer; but, some experiments must be performed in a field setting. The Department of Energy (DOE) Field Lab Observatory projects are designed to address those research questions that must be studied in the field. The Department of Energy (DOE) is developing a suite of "field laboratory" test sites to carry out collaborative research that will help find ways of improving the recovery of energy resources as much as possible, with as little environmental impact as possible, from "unconventional" formations, such as shale and other low permeability rock formations. Currently there are three field laboratories in various stages of development and operation. Work is on-going at two of the sites: The Hydraulic Fracturing Test Site (HFTS) in the Permian Basin and the Marcellus Shale Energy and Environmental Lab (MSEEL) project in the Marcellus Shale Play. Agreement on the third site, the Utica Shale Energy and Environmental Lab (USEEL) project in the Utica Shale Play, was just recently finalized. Other field site opportunities may be forthcoming. This presentation will give an overview of the three field laboratory projects.

Optimization of lift gas allocation in a gas lifted oil field as non-linear optimization problem

Directory of Open Access Journals (Sweden)

Roshan Sharma

2012-01-01

Full Text Available Proper allocation and distribution of lift gas is necessary for maximizing total oil production from a field with gas lifted oil wells. When the supply of the lift gas is limited, the total available gas should be optimally distributed among the oil wells of the field such that the total production of oil from the field is maximized. This paper describes a non-linear optimization problem with constraints associated with the optimal distribution of the lift gas. A non-linear objective function is developed using a simple dynamic model of the oil field where the decision variables represent the lift gas flow rate set points of each oil well of the field. The lift gas optimization problem is solved using the emph'fmincon' solver found in MATLAB. As an alternative and for verification, hill climbing method is utilized for solving the optimization problem. Using both of these methods, it has been shown that after optimization, the total oil production is increased by about 4. For multiple oil wells sharing lift gas from a common source, a cascade control strategy along with a nonlinear steady state optimizer behaves as a self-optimizing control structure when the total supply of lift gas is assumed to be the only input disturbance present in the process. Simulation results show that repeated optimization performed after the first time optimization under the presence of the input disturbance has no effect in the total oil production.

In this study, emissions of ozone precursors from oil and gas operations in Utah's Uinta Basin are predicted (with uncertainty estimates) from 2015-2019 using a Monte-Carlo model of (a) drilling and production activity, and (b) emission factors. Cross-validation tests against actual drilling and production data from 2010-2014 show that the model can accurately predict both types of activities, returning median results that are within 5% of actual values for drilling, 0.1% for oil production, and 4% for gas production. A variety of one-time (drilling) and ongoing (oil and gas production) emission factors for greenhouse gases, methane, and volatile organic compounds (VOCs) are applied to the predicted oil and gas operations. Based on the range of emission factor values reported in the literature, emissions from well completions are the most significant source of emissions, followed by gas transmission and production. We estimate that the annual average VOC emissions rate for the oil and gas industry over the 2010-2015 time period was 44.2E+06 (mean) ± 12.8E+06 (standard deviation) kg VOCs per year (with all applicable emissions reductions). On the same basis, over the 2015-2019 period annual average VOC emissions from oil and gas operations are expected to drop 45% to 24.2E+06 ± 3.43E+06 kg VOCs per year, due to decreases in drilling activity and tighter emission standards. This study improves upon previous methods for estimating emissions of ozone precursors from oil and gas operations in Utah's Uinta Basin by tracking one-time and ongoing emission events on a well-by-well basis. The proposed method has proven highly accurate at predicting drilling and production activity and includes uncertainty estimates to describe the range of potential emissions inventory outcomes. If similar input data are available in other oil and gas producing regions, then the method developed here could be applied to those regions as well.

1999-01-01

There has come a resurgence in the number of companies involved in the oil and gas industry seeking protection from their creditors because of the recent weakness in commodity prices. Because most operations in this industry are conducted jointly, a single insolvency can lead to a toppling of other participants in the joint venture and beyond. The problem is to minimize one's losses if other members of the joint venture become insolvent. An examination is included of some remedies which may be available to operators, non-operators and third parties when faced with an insolvent oil and gas participant. The remedies which may be available to the non-operator that is owed moneys by its operator are discussed. The remedies that the operator has against its non-operators, with an emphasis on the nature of the operator's lien and the right of set-off, are described. A brief review is included of some of the remedies that might be available to a third party as against the operators and non-operators. Some s uggestions are included for directors, bankers, third parties, non-operators and operators

Maximization of Egyptian Gas Oil Production Through the Optimal Use of the Operating Parameters

International Nuclear Information System (INIS)

Marawan, H.

2004-01-01

Gas oil is the major fossil fuel consumed around the world. Global gas oil consumption is rising at a steadily fast pace because of its higher combustion efficiency (versus gasoline). The annual increase rate of gas oil consumption in Egypt is 7 % whereas, the world increase rates range from 1.5 % to 2 % . The main sources for producing gas oil in Egypt refiners is the direct production from the atmospheric distillation process units or it may be produced as a side product from vacuum distillation units . Gas oil is produced through hydrocracking process of vacuum distillation side streams and heavy cocked gas oil. Gas oil production yield can be increased through the existing operation process units. Modifications of the current atmospheric and vacuum tower operations will increase gas oil yield rates to 20 % more than the existing production rates. The modification of the operating conditions and adoption of the optimum catalyst of the existing hydrocracking and mild hydro cracking process units improve gas oil production yield. Operating delayed cocker at high temperatures, low pressure and low cycle ratio also support achieving the maximization of gas oil yield

Mapping reactor operating regimes for heavy gas oil hydrotreating

2011-07-01

Hydrotreating (HDT) is used in oil refineries at temperatures of 350-400 degree C and pressure of 50-100 bars in a fixed bed to improve the quality of distillate fraction. HDT operates as a gas-liquid-solid process, trickle bed. Efforts have been made to model it but volatilization of liquid oil is often ignored. The aim of this paper is to predict vapor-liquid equilibrium (VLE) for a typical heavy distillate feed in pilot plant hydrotreaters. The study was conducted under various operating conditions and a flash calculation program calibrated in-house was used to predict VLE. VLE values were found and results showed that higher pressure, lower gas/oil ratio and temperature should be used to maintain the desired operating regimes when hydrotreating heavy distillate feed. This study determined the operating conditions for maintaining the desired operating regimes and these findings could be useful for operators.

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

The Oil and Gas Field Code Master List 1997 is the sixteenth annual listing of all identified oil and gas fields in the US. It is updated with field information collected through October 1997. The purpose of this publication is to provide unique, standardized codes for identification of domestic fields. Use of these field codes fosters consistency of field identification by government and industry. As a result of their widespread adoption they have in effect become a national standard. The use of field names and codes listed in this publication is required on survey forms and other reports regarding field-specific data collected by EIA. There are 58,366 field records in this year`s FCML, 437 more than last year. The FCML includes: field records for each State and county in which a field resides; field records for each offshore area block in the Gulf of Mexico in which a field resides; field records for each alias field name (definition of alias is listed); fields crossing State boundaries that may be assigned different names by the respective State naming authorities. This report also contains an Invalid Field Record List of 4 records that have been removed from the FCML since last year`s report. These records were found to be either technically incorrect or to represent field names which were never recognized by State naming authorities.

Effect of paraffin saturation in a crude oil on operation of a field

Energy Technology Data Exchange (ETDEWEB)

Trebin, G F; Kapyrin, Yu V

1968-11-01

Both theoretical and practical studies in recent years have shown that in planning operational procedures for an oil field, the paraffin saturation of the crude oil must be considered. If the crude oil is essentially saturated with paraffin at reservoir condition, then paraffin deposition can occur around the well and in the well. Temperature in the reservoir can be lowered by 2 mechanisms: (1) by injection of water below reservoir temperature, and (2) by expansion of produced gas and consequent cooling of the produced oil. Possible application of these principles to several Soviet oil fields is discussed. In the Uzen field, a preliminary investigation is under way to test the feasibility of heating the injection water to prevent paraffin deposition in the reservoir.

Existing transportation fuel cycle emissions models are either general and calculate nonspecific values of greenhouse gas (GHG) emissions from crude oil production, or are not available for public review and auditing. We have developed the Oil Production Greenhouse Gas Emissions Estimator (OPGEE) to provide open-source, transparent, rigorous GHG assessments for use in scientific assessment, regulatory processes, and analysis of GHG mitigation options by producers. OPGEE uses petroleum engineering fundamentals to model emissions from oil and gas production operations. We introduce OPGEE and explain the methods and assumptions used in its construction. We run OPGEE on a small set of fictional oil fields and explore model sensitivity to selected input parameters. Results show that upstream emissions from petroleum production operations can vary from 3 gCO2/MJ to over 30 gCO2/MJ using realistic ranges of input parameters. Significant drivers of emissions variation are steam injection rates, water handling requirements, and rates of flaring of associated gas.

1991-01-01

This paper presents an overview of a waste gas treatment system designed to control emissions from thermally enhanced oil recovery wells. This case study discusses the need, design, installation and operations of the system. Oryx Energy Company (Oryx) operates approximately 940 wells in the Midway-Sunset (MWSS) field under casing vapor recovery systems. The emissions collected from well casing vent gas cotaining hydrocarbons and hydrogen sulfide that are collected and processed through casing vapor recovery skids. These skids are composed of condensers, compressors, and pumps that separate fluids from the waste gas stream. The non-condensible gas is then disposed of in incinerators that reduce the hydrocarbon and sulfur emissions into the atmosphere. Approximately 91,000 lbs/day of hydrocarbon and 10,116 lbs/day of sulfur dioxide are removed from the atmosphere from wells contained within these systems operated by Oryx. These hydrocarbons yield approximately 550 barrels of oil per day (BOPD). The system helps manage the pressure differential from the reservoir into each wellbore and contributes to improved ambient air quality in Kern County, California

This paper presents operating and performance characteristics of a nine-stack solid-oxide fuel cell combined-heat-and-power system. Integrated with a natural-gas fuel processor, air compressor, reactant-gas preheater, and diagnostics and control equipment, the system is designed for use in unconventional oil-and-gas processing. Termed a ;Geothermic Fuel Cell; (GFC), the heat liberated by the fuel cell during electricity generation is harnessed to process oil shale into high-quality crude oil and natural gas. The 1.5-kWe SOFC stacks are packaged within three-stack GFC modules. Three GFC modules are mechanically and electrically coupled to a reactant-gas preheater and installed within the earth. During operation, significant heat is conducted from the Geothermic Fuel Cell to the surrounding geology. The complete system was continuously operated on hydrogen and natural-gas fuels for ∼600 h. A quasi-steady operating point was established to favor heat generation (29.1 kWth) over electricity production (4.4 kWe). Thermodynamic analysis reveals a combined-heat-and-power efficiency of 55% at this condition. Heat flux to the geology averaged 3.2 kW m-1 across the 9-m length of the Geothermic Fuel Cell-preheater assembly. System performance is reviewed; some suggestions for improvement are proposed.

Integrated field modelling[Oil and gas fields

2002-07-01

This research project studies the feasibility of developing and applying an integrated field simulator to simulate the production performance of an entire oil or gas field. It integrates the performance of the reservoir, the wells, the chokes, the gathering system, the surface processing facilities and whenever applicable, gas and water injection systems. The approach adopted for developing the integrated simulator is to couple existing commercial reservoir and process simulators using available linking technologies. The simulators are dynamically linked and customised into a single hybrid application that benefits from the concept of open software architecture. The integrated field simulator is linked to an optimisation routine developed based on the genetic algorithm search strategies. This enables optimisation of the system at field level, from the reservoir to the process. Modelling the wells and the gathering network is achieved by customising the process simulator. This study demonstrated that the integrated simulation improves current capabilities to simulate the performance of the entire field and optimise its design. This is achieved by evaluating design options including spread and layout of the wells and gathering system, processing alternatives, reservoir development schemes and production strategies. Effectiveness of the integrated simulator is demonstrated and tested through several field-level case studies that discuss and investigate technical problems relevant to offshore field development. The case studies cover topics such as process optimisation, optimum tie-in of satellite wells into existing process facilities, optimal well location and field layout assessment of a high pressure high temperature deepwater oil field. Case study results confirm the viability of the total field simulator by demonstrating that the field performance simulation and optimal design were obtained in an automated process with treasonable computation time.

Thomas, A.

1994-01-01

To achieve its goal of becoming Canada's premier oil and gas company by the year 2000, Mobil Oil Canada is empowering its employees and applying appropriate technology to unlock resources and create value. Mobil produces 4.1 million m 3 of oil and natural gas liquids, 5.6 million m 3 /y of natural gas and 438,000 tonnes/y of sulfur. It also operates over 3,000 wells in western Canada and eleven gas processing plants, manages 1,700 km of pipeline, and has 33% interest in the Hibernia project on the Grand Banks. Oil lifting costs have decreased over the past three years from $3.40/bbl to $2.80/bbl and development costs are under $2/bbl. Innovative technology used to achieve high production and low costs include the use of three dimensional seismic surveys and horizontal drilling. Other techniques used at particular sites include installation of downhole injection regulators to control problems of segregation and metering between different water injection zones at the Carson Creek field, use of artificial lifts in gas wells, and a dual gas lift at the Rainbow Lake oil field. At the Lone Pine gas plant, the first Superclaus-99 sulfur recovery process was installed, reducing sulfur emissions by 60% and increasing recovery efficiency from 95% to 98%. Mobil has operated in Canada since 1940 and has made significant discoveries, including Canada's largest producing oil field, the Pembina. In 1971, Mobil discovered gas of commercial significance off the east coast and helped discover the Hibernia and Venture fields. The Hibernia project is scheduled to come on stream in 1997 and Mobil expects the economics of the project to be favorable, with a $12-13/bbl oil price needed to break even. 7 figs

Artificial intelligence applications in offshore oil and gas production

Attia, F.G.

1994-01-01

The field of Artificial Intelligence (AI) has gained considerable acceptance in virtually all fields, of engineering applications. Artificial intelligence is now being applied in several areas of offshore oil and gas operations, such as drilling, well testing, well logging and interpretation, reservoir engineering, planning and economic evaluation, process control, and risk analysis. Current AI techniques offer a new and exciting technology for solving problems in the oil and gas industry. Expert systems, fuzzy logic systems, neural networks and genetic algorithms are major AI technologies which have made an impact on the petroleum industry. Presently, these technologies are at different stages of maturity with expert systems being the most mature and genetic algorithms the least. However, all four technologies have evolved such that practical applications were produced. This paper describes the four major Al techniques and their many applications in offshore oil and gas production operations. A summary description of future developments in Al technology that will affect the execution and productivity of offshore operations will be also provided

Identification, Verification, and Compilation of Produced Water Management Practices for Conventional Oil and Gas Production Operations

Energy Technology Data Exchange (ETDEWEB)

Rachel Henderson

2007-09-30

The project is titled 'Identification, Verification, and Compilation of Produced Water Management Practices for Conventional Oil and Gas Production Operations'. The Interstate Oil and Gas Compact Commission (IOGCC), headquartered in Oklahoma City, Oklahoma, is the principal investigator and the IOGCC has partnered with ALL Consulting, Inc., headquartered in Tulsa, Oklahoma, in this project. State agencies that also have partnered in the project are the Wyoming Oil and Gas Conservation Commission, the Montana Board of Oil and Gas Conservation, the Kansas Oil and Gas Conservation Division, the Oklahoma Oil and Gas Conservation Division and the Alaska Oil and Gas Conservation Commission. The objective is to characterize produced water quality and management practices for the handling, treating, and disposing of produced water from conventional oil and gas operations throughout the industry nationwide. Water produced from these operations varies greatly in quality and quantity and is often the single largest barrier to the economic viability of wells. The lack of data, coupled with renewed emphasis on domestic oil and gas development, has prompted many experts to speculate that the number of wells drilled over the next 20 years will approach 3 million, or near the number of current wells. This level of exploration and development undoubtedly will draw the attention of environmental communities, focusing their concerns on produced water management based on perceived potential impacts to fresh water resources. Therefore, it is imperative that produced water management practices be performed in a manner that best minimizes environmental impacts. This is being accomplished by compiling current best management practices for produced water from conventional oil and gas operations and to develop an analysis tool based on a geographic information system (GIS) to assist in the understanding of watershed-issued permits. That would allow management costs to be kept in

Methane emissions due to oil and natural gas operations in the Netherlands

International Nuclear Information System (INIS)

Oonk, J.; Vosbeek, M.E.J.P.

1995-01-01

The Netherlands is the 4th largest natural gas producer, with about 4% of the total world natural gas production. Also, significant amounts of oil are extracted. For this reason it can be expected that methane emissions from oil and natural gas operations contribute significantly to total methane emissions. Estimates so far, made by both the Dutch government and the industry vary widely. A renewed estimate is made of methane emissions from oil and natural gas production, based on a detailed engineering study of sources of methane in the system and quantification of source strengths. The estimate is validated by interpretation of atmospheric measurements. 1990 methane emissions from natural gas production were estimated to be 62 to 108 kton. The main cause of methane emissions is the venting of off-gases from processes and passing-valve emissions in the off-shore. Emissions from oil production were estimated to be 14 kton, mainly caused by venting of off-gases from processes. Best feasible options for emission reduction are: identification and replacement of leaking valves, and reuse or re-compression of off-gases from processes. Both options are existing policy in the Netherlands. 23 figs., 38 tabs., 2 appendices, 53 refs

Effective use of complex secondary recovery methods in operation of small oil fields

Ibragimov, M R; Akulov, V P; Khutorov, A M

1966-11-01

The North Sokhs Field, located in the southern part of the Fergen depression, is composed of many horizons and has an anticlinal structure. The eighth horizon has highest oil saturation, with an average porosity of 17% and permeability of 80 md. Poor oil recovery was initially obtained from this horizon because the basic producing mechanism was solution gas drive. In 1961, when reservoir pressure was 94 kg/cmU2D and gas factor was 700-800mU3D/ton, pressure maintenance was initiated by injection of gas to the structure. Gas injection improved oil recovery considerably; however, high gas-oil ratios appeared in several wells. Next, peripheral water injection was started, and continued simultaneously with gas injection. The simultaneous injection of gas and water almost doubled oil production. Because of continued, high produced gas/oil ratios, gas injection was eventually discontinued, while water injection was continued. Water injection is building up reservoir pressure and improving oil recovery.

The oil and gas industry in Bolivia is discussed. Typically, the hydrocarbon production of the Bolivian fields is made up of very light oil and natural gas, both of very good quality with no deleterious contaminants. About 80% of the production comes from gas condensate fields. At present, the proven gas reserves are more than 6 trillion cubic feet that have been available for the last 10 years, notwithstanding the fact that 200 million cubic feet per day are exported

Oil and gas operational and policy issues in the UK

International Nuclear Information System (INIS)

Howard, D.

1992-01-01

The method of arriving at monthly values under Schedule 3 OTA 1975 applies to all oil which can include LPG and condensate as well as crude oil and gas. The majority of crude oil is now sold spot and in 1987 the method of arriving at monthly values was amended better to reflect this aspect of the crude oil market. The UK gas market was such that the proceeds of sale of large amounts of natural gas were exempt from PRT under Section 10 OTA 1975 and very little gas was disposed of other than at arms length to British Gas. British Gas no longer buys virtually all gas produced from the UK Continental Shelf and neither does it sell all the gas used by UK customers. The use of natural gas to generate electricity has opened up a new market for UK landed gas. How do these changes affect gas valuation.?. (Author)

More than half a century ago, Academician PN Kropotkin substantiated the relationship of the formation and distribution of oil and gas fields with the processes of emanation hydrocarbon degassing of the Earth. Over the years, the concept of PN Kropotkin received further development and recognition of studies based on new factual material. Of particular importance are the following factors: a) the results of studies on global and regional uneven processes of traditional oil and gas and the role of deep faults in controlling the spread of oil and gas fields; b) the results of the research on gigantic volumes and localization of the discharges of hydrocarbon fluids (mud volcanoes, seeps) on land and into the atmosphere and through the bottom of the World ocean; c) the results of the studies on grand volumes of the spread of unconventional hydrocarbon resources in their non-traditional fields, especially on near-surface interval of unconventional oil and gas accumulation with gas hydrates, heavy oil and bitumen, as well as extraordinary resources of oil and gas in the shale and tight rocks. Deep mantle-crust nature of oil and gas in traditional and nontraditional deposits thus received further substantiation of geological and geophysical data and research results. However, isotopic and geochemical data are still interpreted in favor of the concept of the genesis of oil and gas in the processes of thermal catalytic conversion of organic matter of sedimentary rocks, at temperatures up to 200°C. In this report an alternative interpretation of the isotope carbon-hydrogen system (δ13C-δD) for gas and of oil deposits, isotope carbon system for methane and carbon dioxide (δ13C1-δ13C0) will be presented. An alternative interpretation will also be presented for the data on carbon-helium isotope geochemical system for oil and gas fields, volcanoes and mud volcanoes. These constructions agree with the geological data on the nature of deep hydrocarbon fluids involved in the

This study focuses on the factors behind Kazakhstan's decision to renegotiate the terms of the existing Production Sharing Agreements (PSAs) with International Oil Companies (IOCs), in the context of the development of the huge Kashagan oil field. The development of Kashagan, one of the largest and most recently discovered oil fields in Kazakhstan, is crucial for Kazakhstan's ambitions of becoming a global oil producer. Kazakhstan, which has the largest oil reserves in the Caspian Sea region, is the second largest regional producer after Russia in the former Soviet Union. The country's potential for oil exports is also strategically significant as a future source of non- OPEC supplies. Amongst the CIS states, Kazakhstan is considered one of the most open countries for foreign investments. International projects in the form of Joint Ventures, Production Sharing Agreements (PSAs) or exploration/field concessions have brought foreign investments into the country's natural resources sector, particularly in the oil and gas industry. However, new developments have recently taken place, which have marked a shift in the Kazakh government's approach towards foreign investment in its energy sector. This study will therefore examine the following issues: - Kazakhstan's plans to abandon the practice of attracting foreign investments in its energy sector through new PSAs. - The recent entry of state-controlled KazMunaiGaz into the consortium operating over the Kashagan field and its impact on IOCs. - The impact of high oil prices on the negotiating power of producer states in the context of Kazakhstan's new stance on PSAs. Specifically, this study will focus on the following key factors, which will seek to further explain the changes in Kazakhstan's attitude toward the Kashagan PSA2: - Operational factors - management of the project, development strategy, cost estimates, levels of production and export markets. - Consortium factors - the relative strength of the investment

Recovery of Fresh Water Resources from Desalination of Brine Produced During Oil and Gas Production Operations

Energy Technology Data Exchange (ETDEWEB)

Management and disposal of produced water is one of the most important problems associated with oil and gas (O&G) production. O&G production operations generate large volumes of brine water along with the petroleum resource. Currently, produced water is treated as a waste and is not available for any beneficial purposes for the communities where oil and gas is produced. Produced water contains different contaminants that must be removed before it can be used for any beneficial surface applications. Arid areas like west Texas produce large amount of oil, but, at the same time, have a shortage of potable water. A multidisciplinary team headed by researchers from Texas A&M University has spent more than six years is developing advanced membrane filtration processes for treating oil field produced brines The government-industry cooperative joint venture has been managed by the Global Petroleum Research Institute (GPRI). The goal of the project has been to demonstrate that treatment of oil field waste water for re-use will reduce water handling costs by 50% or greater. Our work has included (1) integrating advanced materials into existing prototype units and (2) operating short and long-term field testing with full size process trains. Testing at A&M has allowed us to upgrade our existing units with improved pre-treatment oil removal techniques and new oil tolerant RO membranes. We have also been able to perform extended testing in 'field laboratories' to gather much needed extended run time data on filter salt rejection efficiency and plugging characteristics of the process train. The Program Report describes work to evaluate the technical and economical feasibility of treating produced water with a combination of different separation processes to obtain water of agricultural water quality standards. Experiments were done for the pretreatment of produced water using a new liquid-liquid centrifuge, organoclay and microfiltration and ultrafiltration membranes

Model improves oil field operating cost estimates

International Nuclear Information System (INIS)

Glaeser, J.L.

1996-01-01

A detailed operating cost model that forecasts operating cost profiles toward the end of a field's life should be constructed for testing depletion strategies and plans for major oil fields. Developing a good understanding of future operating cost trends is important. Incorrectly forecasting the trend can result in bad decision making regarding investments and reservoir operating strategies. Recent projects show that significant operating expense reductions can be made in the latter stages o field depletion without significantly reducing the expected ultimate recoverable reserves. Predicting future operating cost trends is especially important for operators who are currently producing a field and must forecast the economic limit of the property. For reasons presented in this article, it is usually not correct to either assume that operating expense stays fixed in dollar terms throughout the lifetime of a field, nor is it correct to assume that operating costs stay fixed on a dollar per barrel basis

An extensive set of volatile organic compounds (VOCs) was measured at the Boulder Atmospheric Observatory (BAO) in winter 2011 in order to investigate the composition and influence of VOC emissions from oil and natural gas (O&NG) operations in northeastern Colorado. BAO is 30 km north of Denver and is in the southwestern section of Wattenberg Field, one of Colorado's most productive O&NG fields. We compare VOC concentrations at BAO to those of other U.S. cities and summertime measurements at two additional sites in northeastern Colorado, as well as the composition of raw natural gas from Wattenberg Field. These comparisons show that (i) the VOC source signature associated with O&NG operations can be clearly differentiated from urban sources dominated by vehicular exhaust, and (ii) VOCs emitted from O&NG operations are evident at all three measurement sites in northeastern Colorado. At BAO, the reactivity of VOCs with the hydroxyl radical (OH) was dominated by C(2)-C(6) alkanes due to their remarkably large abundances (e.g., mean propane = 27.2 ppbv). Through statistical regression analysis, we estimate that on average 55 ± 18% of the VOC-OH reactivity was attributable to emissions from O&NG operations indicating that these emissions are a significant source of ozone precursors.

acceptable, economically profitable and socially responsible. This dissertation discusses the framework of true 'sustainability' for practically all aspects oil and gas operations and nature-based resource operations. Sustainability of existing offshore oil and gas operations techniques are analyzed and new nature-based technologies are proposed. Also evaluated are the fate and effect, environmental impact, risk factors, and the green supply chain in the case of seismic, drilling, production and decommissioning of oil operations. It is demonstrated with detailed examples that using the new approach will be economically more beneficial than the conventional approach, even in the short-term. The dissertation also examines the present status of petroleum operations with respect to waste generation, improper resource management, and the usage of toxic compounds in the overall lifecycle. To achieve true sustainability, some innovative models and technologies are presented. They include achievement of zero emissions, zero waste of resources, zero waste in activities, zero use of toxics, and zero waste in product life-cycle. This dissertation also discusses the environmental and technological problems of the petroleum sector and provides guidelines to achieve overall sustainability in oil company activities. Finally, this dissertation shows that inherent sustainability can be achieved by the involvement of community participation. The new screening tool proposed in this dissertation provides proper guidelines to achieve true sustainability in the technology development and other resource development operations.

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

2016-04-01

Full Text Available In offshore industry activities, the suitable onboard provision of assets location and geospatial marine information during operations is essential. Currently, most companies use its own data structures, resulting in incompatibility between processes. In order to promote the data exchange, oil and gas industry associations have pursued initiatives to standardize spatial information. In turn, the IMO - International Maritime Organization - started the implementation of e-Navigation policy, which is the standardization of technologies and protocols applied to maritime information and navigation. This paper shows relationship and integration points between maritime activities of oil and gas industry and e-Navigation technologies and processes, highlighting geospatial information. This paper also preludes out an initiative for a suitable product specification for the offshore oil and gas industry, compliant with e-Navigation and IHO S-100 international standards.

Oil and gas industry in the Great Jamahiriya is one of those industries that were accompanied with generation of some solid and liquid waste, which associated with risks that might lead to harmful effects to the man and the environment. Among those risks the continuous increase of radioactivity levels above natural radioactive background around operating oil fields, due to accumulation of solid and liquid radioactive scales and sludge as well as contaminated produced water that contain some naturally occurring radioactive materials ( NORM/TE-NORM). Emergence of NORM/TE-NORM in studied area noticed when the natural background radioactivity levels increased around some oil fields during end of 1998, For this study, six field trips and a radiation surveys were conducted within selected oil fields that managed and owned by six operating companies under NOC, in order to determine the effective radiation dose in contrast with dose limits set by International Counsel of Radiation Protection(ICRP),and International Atomic Energy Agency(IAEA) Additionally solid samples in a form of scales and liquid samples were also taken for further investigation and laboratory analysis. Results were tabulated and discussed within the text .However to be more specific results pointed out to the fact that existence of NORM/TE-NORM as 226 Ra, 228 Ra, within some scale samples from surface equipment in some oil and gas fields in Jamahiriya were significant. As a result of that, the workers might receive moderate radiation dose less than the limits set by ICRP,IAEA, and other parts of the world producing oil and gas. Results predicted that within the investigated oil fields if workers receive proper training about handling of NORM/TE-NORM and follow the operating procedure of clean ups, work over and maintenance plane carefully, their committed exposure from NORM/TE-NORM will be less than the set limits by ICRP and IAEA. In a trend to estimate internal radiation dose as a result of possible

The development and application of dynamic operational risk assessment in oil/gas and chemical process industry

International Nuclear Information System (INIS)

Yang Xiaole; Mannan, M. Sam

2010-01-01

A methodology of dynamic operational risk assessment (DORA) is proposed for operational risk analysis in oil/gas and chemical industries. The methodology is introduced comprehensively starting from the conceptual framework design to mathematical modeling and to decision making based on cost-benefit analysis. The probabilistic modeling part of DORA integrates stochastic modeling and process dynamics modeling to evaluate operational risk. The stochastic system-state trajectory is modeled according to the abnormal behavior or failure of each component. For each of the possible system-state trajectories, a process dynamics evaluation is carried out to check whether process variables, e.g., level, flow rate, temperature, pressure, or chemical concentration, remain in their desirable regions. Component testing/inspection intervals and repair times are critical parameters to define the system-state configuration, and play an important role for evaluating the probability of operational failure. This methodology not only provides a framework to evaluate the dynamic operational risk in oil/gas and chemical industries, but also guides the process design and further optimization. To illustrate the probabilistic study, we present a case-study of a level control in an oil/gas separator at an offshore plant.

VSAT: opening new horizons to oil and gas explorations

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

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

The current technology to produce shale oil reservoirs is the primary depletion using fractured wells (generally horizontal wells). The oil recovery is less than 10%. The prize to enhance oil recovery (EOR) is big. Based on our earlier simulation study, huff-n-puff gas injection has the highest EOR potential. This project was to explore the potential extensively and from broader aspects. The huff-n-puff gas injection was compared with gas flooding, water huff-n-puff and waterflooding. The potential to mitigate liquid blockage was also studied and the gas huff-n-puff method was compared with other solvent methods. Field pilot tests were initiated but terminated owing to the low oil price and the operator’s budget cut. To meet the original project objectives, efforts were made to review existing and relevant field projects in shale and tight reservoirs. The fundamental flow in nanopores was also studied.

1997-08-01

Texas State Lands oil and gas resources are estimated at 1.6 BSTB of remaining mobile oil, 2.1 BSTB, or residual oil, and nearly 10 Tcf of remaining gas. An integrated, detailed geologic and engineering characterization of Texas State Lands has created quantitative descriptions of the oil and gas reservoirs, resulting in delineation of untapped, bypassed compartments and zones of remaining oil and gas. On Texas State Lands, the knowledge gained from such interpretative, quantitative reservoir descriptions has been the basis for designing optimized recovery strategies, including well deepening, recompletions, workovers, targeted infill drilling, injection profile modification, and waterflood optimization. The State of Texas Advanced Resource Recovery program is currently evaluating oil and gas fields along the Gulf Coast (South Copano Bay and Umbrella Point fields) and in the Permian Basin (Keystone East, Ozona, Geraldine Ford and Ford West fields). The program is grounded in advanced reservoir characterization techniques that define the residence of unrecovered oil and gas remaining in select State Land reservoirs. Integral to the program is collaboration with operators in order to deploy advanced reservoir exploitation and management plans. These plans are made on the basis of a thorough understanding of internal reservoir architecture and its controls on remaining oil and gas distribution. Continued accurate, detailed Texas State Lands reservoir description and characterization will ensure deployment of the most current and economically viable recovery technologies and strategies available.

History and performance of the Steelman Oil Field, Saskatchewan

Energy Technology Data Exchange (ETDEWEB)

Nikolaychuk, J; Francis, R E

1965-01-01

This paper summarizes the development and performance of the Steelman oil field in southeastern Saskatchewan. Steelman was the first field in southeastern Saskatchewan in which pressure maintenance by waterflooding was attempted. Production is obtained, at a depth of 4,700 ft, mainly from the dolomitized limestone Midale beds reservoir. Some production is also obtained from the underlying Frobisher beds, but the productive development of this zone is quite sporadic. The discovery of the field in 1954 was followed by the drilling of approximately 800 wells on 80-acre spacing. An early decline in reservoir pressure and increasing gas-oil ratios in this solution gas drive reservoir caused the working-interest owners to unitize most of the field and institute a program of pressure maintenance by waterflooding. The bulk of the field is unitized as 6 separate units, with pressure maintenance being conducted by three operators. To the end of 1964, the cumulative oil production from the six-unit area was approximately 77,000,000 bpd.

The Netherlands: development of oil and gas reserves

International Nuclear Information System (INIS)

1993-01-01

Oil was first discovered in The Netherlands in the late 1930s near The Hague. Later the larger onshore field at Schoonebeek was found. In the 1960s significant resources of oil were discovered in the Dutch sector of the North Sea. However onshore oil still provides about 20% of the nation's requirements. In the 1960s the vast size of the onshore Groningen gas field became apparent and its subsequent development has provided the Dutch with a huge source of wealth. In recent years the Dutch Continental Shelf has also yielded substantial reserves of gas, although these are not yet as important as the onshore gas reserves. Dutch Government policy is designed to encourage the development of smaller offshore gas fields thereby conserving the Gronigen field. Dutch oil and gas production, licensing and drilling activities are discussed, and the prospects for British suppliers is considered. (author)

2003-07-01

In response to growing demands from the Norwegian oil and gas industry, a joint industry project on the development and implementation of operations and maintenance performance indicators for the petroleum industry was initiated by the Center for Asset and Maintenance Management of Stavanger University College, Norway, in 1999. The project consortium composed of BP, Shell, Philips, Statoil, NorskHydro, Norwegian Petroleum Directorate, PricewaterhouseCoopers, Andersen Consulting, DNV, Industrial and Financial Systems (IFS), ADB Systems AS, DNV, RC Consultants and Tieto Enator. While the project was managed effectively to serve the expectations of member organizations, its boundaries were predefined by various conditions within organizational environments leaving a substantial space unexplored. Hence, the width and the breadth of operations and maintenance performance captured by the project were largely limited. This called for an independent research study to explore the phenomenon with a more broader or holistic perspective. Notably thus, while the project was devoted to a down-to-earth component of the exercise, i.e. to develop performance indicators, the exploratory research study was launched alongside to bring a theoretical or a philosophical insight. The study was conducted during 2000-2002 with collaboration of 14 organizations within the Norwegian continental shelf. The population included oil and gas producers regulatory and verification bodies and third parties. The study identified the bulk of problems that the entire problem domain constitute of within operations and maintenance performance. They were classified into some theoretical forms, and the study concentrated on, what I term, technical alienation, i.e. lack of descriptive performance models to guide meaningful assessment and management of operations and maintenance performance. The choice to shed some light in this endeavor was based on the relevance to SDV project, emerging managerial interest

The project consortium composed of BP, Shell, Philips, Statoil, NorskHydro, Norwegian Petroleum Directorate, PricewaterhouseCoopers, Andersen Consulting, DNV, Industrial and Financial Systems (IFS), ADB Systems AS, DNV, RC Consultants and Tieto Enator. While the project was managed effectively to serve the expectations of member organizations, its boundaries were predefined by various conditions within organizational environments leaving a substantial space unexplored. Hence, the width and the breadth of operations and maintenance performance captured by the project were largely limited. This called for an independent research study to explore the phenomenon with a more broader or holistic perspective. Notably thus, while the project was devoted to a down-to-earth component of the exercise, i.e. to develop performance indicators, the exploratory research study was launched alongside to bring a theoretical or a philosophical insight. The study was conducted during 2000-2002 with collaboration of 14 organizations within the Norwegian continental shelf. The population included oil and gas producers regulatory and verification bodies and third parties. The study identified the bulk of problems that the entire problem domain constitute of within operations and maintenance performance. They were classified into some theoretical forms, and the study concentrated on, what I term, technical alienation, i.e. lack of descriptive performance models to guide meaningful assessment and management of operations and maintenance performance. The choice to shed some light in this endeavor was based on the relevance to SDV project, emerging managerial interest

Partial combustion of biomass in the gasifier generates producer gas that can be used as supplementary or sole fuel for internal combustion engines. Dual fuel mode operation using coir-pith derived producer gas and rubber seed oil as pilot fuel was analyzed for various producer gas-air flow ratios and at different load conditions. The engine is experimentally optimized with respect to maximum pilot fuel savings in the dual fuel mode operation. The performance and emission characteristics of the dual fuel engine are compared with that of diesel engine at different load conditions. Specific energy consumption in the dual-fuel mode of operation with oil-coir-pith operation is found to be in the higher side at all load conditions. Exhaust emission was found to be higher in the case of dual fuel mode of operation as compared to neat diesel/oil operation. Engine performance characteristics are inferior in fully renewable fueled engine operation but it suitable for stationary engine application, particularly power generation. (author)

Energy Technology Data Exchange (ETDEWEB)

Bakhtin, V.V.

1979-09-01

We studied the origin of injection halos of hydrocarbons above oil-gas fields with anomalously high formation pressures (AHFP). Using fields in Azerbaydzhan and Chechen-Ingushetiya as an example, we demonstrate the effect of certain factors (in particular, faults and zones of increased macro- and micro-jointing) on the morpholoy of the halos. The intensity of micro-jointing (jointing permeability, three-dimensional density of micro-jointing) is directly connected with vertical dimensions of the halos. We measured halos based on transverse profiles across the Khayan-Kort field and studied the distribution of bitumen saturation within the injection halo. Discovery of injection halos during drilling has enabled us to improve the technology of wiring deep-seated exploratory wells for oil and gas in regions with development of AHFP.

Full Text Available In the Yingdong Oil/Gas Field of the Qaidam Basin, multiple suites of oil-gas-water systems overlie each other vertically, making it difficult to accurately identify oil layers from gas layers and calculate gas-oil ratio (GOR. Therefore, formation testing and production data, together with conventional logging, NMR and mud logging data were integrated to quantitatively calculate GOR. To tell oil layers from gas layers, conventional logging makes use of the excavation effect of compensated neutron log, NMR makes use of the different relaxation mechanisms of light oil and natural gas in large pores, while mud logging makes use of star chart of gas components established based on available charts and mathematical statistics. In terms of the quantitative calculation of GOR, the area ratio of the star chart of gas components was first used in GOR calculation. The study shows that: (1 conventional logging data has a modest performance in distinguishing oil layers from gas layers due to the impacts of formation pressure, hydrogen index (HI, shale content, borehole conditions and invasion of drilling mud; (2 NMR is quite effective in telling oil layers from gas layers, but cannot be widely used due to its high cost; (3 by contrast, the star chart of gas components is the most effective in differentiating oil layers from gas layers; and (4 the GOR calculated by using the area ratio of star chart has been verified by various data such as formation testing data, production data and liquid production profile.

The U.S. Energy Information Administration has reported a sharp increase in domestic oil and natural gas production from "unconventional" reserves (e.g., shale and tight sands) between 2005 and 2012. The recent growth in drilling and fossil fuel production has led to environmental concerns regarding local air quality. Severe wintertime ozone events (greater than 100 ppb ozone) have been observed in Utah's Uintah Basin and Wyoming's Upper Green River Basin, both of which contain large natural gas fields. Raw natural gas is a mixture of approximately 60-95 mole percent methane while the remaining fraction is composed of volatile organic compounds (VOCs) and other non-hydrocarbon gases. We measured an extensive set of VOCs and other trace gases near two highly active areas of oil and natural gas production in Utah's Uintah Basin and Colorado's Denver-Julesburg Basin in order to characterize primary emissions of VOCs associated with these industrial operations and identify the key VOCs that are precursors for potential ozone formation. UBWOS (Uintah Basin Winter Ozone Study) was conducted in Uintah County located in northeastern Utah in January-February 2012. Two Colorado studies were conducted at NOAA's Boulder Atmospheric Observatory in Weld County in northeastern Colorado in February-March 2011 and July-August 2012 as part of the NACHTT (Nitrogen, Aerosol Composition, and Halogens on a Tall Tower) and SONNE (Summer Ozone Near Natural gas Emissions) field experiments, respectively. The C2-C6 hydrocarbons were greatly enhanced for all of these studies. For example, the average propane mixing ratio observed during the Utah study was 58 ppb (median = 35 ppb, minimum = 0.8, maximum = 520 ppb propane) compared to urban averages which range between 0.3 and 6.0 ppb propane. We compare the ambient air composition from these studies to urban measurements in order to show that the VOC source signature from oil and natural gas operations is distinct and can be clearly

1978-01-01

Present and future water pollution problems resulting from oil field operations in Alabama are analyzed. An outline of a program of data collection and interpretation necessary to determine and evaluate solutions to these problems is presented. A method of adequate monitoring of the oil and gas fields in Alabama to protect against pollution of its valuable surface and groundwater supplies is described. Samples of brine are continuously collected and analyzed from sources representing all water producing horizons in the oil fields. A network of observation wells has been established in oil fields to periodically determine changes in the chemical quality of groundwaters. Water samples from wells adjacent to all major saltwater evaporation pits have been collected and analyzed for possible changes in chemical quality. Discharge measurements are made on streams adjacent to all oil fields. Periodic aerial photographs are being made of each field. Preliminary administrative reports are regularly prepared on each problem in the oil fields and remedial or disciplinary actions are taken by the Oil and Gas Board.

How wireless remote technology reduces cost, boosts productivity and improves safety in upstream oil and gas operations

Energy Technology Data Exchange (ETDEWEB)

Wommack, K. [Viatran, Edmonton, AB (Canada)

2009-09-15

This article demonstrated how wireless communications can help oil and gas producers obtain the most current information on the status of their operations to help optimize operations and protect workers and equipment. Wireless communication can provide benefits at nearly every phase of upstream production. When combined with pressure, temperature, flow, level and other sensing devices, wireless communications provide an effective and economical way to deliver data on well or pipeline operations to site managers; optimize well-production, minimize workovers and prevent blowdowns at the wellhead; track oil and water production; measure differential pressure, line pressure and line temperature; and monitor the motorized choke and control valve position. Wireless technology offers significant savings through improved maintenance efficiency. With wireless systems in remote locations, there are seldom problems in the transmission path. Wireless technology makes it much easier and affordable to manage well operations from a safe distance. By eliminating the need for wires in a fracing operation, wireless can help fracing companies maintain a safe operating distance from their target wells, and move operations from well to well with ease. A wireless communication system for transmitting process data from field sensors to a field processing device consists of radio transmitters, a communications gateway and a user interface. The communications hub receives encrypted messages from the remote devices and transmits them to a flow computer, SCADA system, or Distributed Control System. Data is then transmitted to a central office. 1 fig.

Recent experience with onshore oil and gas operations in the Mackenzie Delta, NWT

International Nuclear Information System (INIS)

Burns, J.

1999-01-01

Hydrocarbon deposits in the Beaufort Sea and Mackenzie Delta indicate mean discovered gas reserves of 5 trillion cubic feet of natural gas, 67 million barrels of condensate, and 247 million barrels of oil in fields located onshore. There may be even bigger undiscovered reserves that could be proven by a surge in drilling likely to occur in this region within the next few years. There are a number of characteristics of this area that appeal to the oil and gas industry over and above the discovered and undiscovered reserves. There is a local aboriginal group with a settled land claim, clear and reasonable rules for access, a business-like approach to development and a sophisicated understanding of the oil and gas industry. There is reasonable access by road, commercial air service, rail and barge by Hay river or sea with an excellent harbour at Tuktoyaktuk. Local contractors and labour with applicable skills and good equipment are available. The Inuvialuit Petroleum Corp. and its partners Altagas Services Inc. and Enbridge Inc. completed a project to supply the town of Inuvik with natural gas for electricity generation and local distribution. This project is a small example of the physical, economic and regulatory environments that the oil industry will face with the undertaking of larger projects. Aspects of the region described include: the Inuvialuit, recent experience, logistics, regulatory environment, project approvels, environmental, and specific observations

Analysis of the orderly distribution of oil and gas fields in China based on the theory of co-control of source and heat

Directory of Open Access Journals (Sweden)

Gongcheng Zhang

2015-01-01

Full Text Available Taking a hydrocarbon zone or a basin group as a unit, this paper analyzed the vertical hydrocarbon generation regularity of onshore and offshore oil and gas fields in China, based on the theory of co-control of source and heat. The results demonstrated that the hydrocarbon generation modes of oil and gas fields in China are orderly. First, the hydrocarbon zones in southeastern China offshore area, including the East and South China Sea basins, are dominated by single hydrocarbon generation mode, which displays as either single oil generation in the near shore or single gas generation in the offshore controlled by both source and heat. Second, the eastern hydrocarbon zones, including the Bohai Bay, Songliao and Jianghan basins and the North and South Yellow Sea basins, are dominated by a two-layer hydrocarbon generation mode, which performs as “upper oil and lower gas”. Third, the central hydrocarbon zones, including the Ordos, Sichuan and Chuxiong basins, are also dominated by the “upper oil and lower gas” two-layer hydrocarbon generation mode. In the Ordos Basin, gas is mainly generated in the Triassic, and oil is predominantly generated in the Paleozoic. In the Sichuan Basin, oil was discovered in the Jurassic, and gas was mostly discovered in the Sinian and Triassic. Fourth, the western hydrocarbon zones are dominated by a “sandwich” multi-layer mode, such as the Junggar, Tarim, Qaidam basins. In summary, the theory of co-control of source and heat will be widely applied to oil and gas exploration all over China. Oil targets should be focused on the near shore areas in the southeastern China sea, the upper strata in the eastern and middle hydrocarbon zones, and the Ordovician, Permian and Paleogene strata in the western hydrocarbon zone, while gas targets should be focused on the off-shore areas in the southeastern China sea, the Cambrian, Carboniferous, Jurassic, and Quaternary strata in the western hydrocarbon zone.

Business co-operation with various foreign partners has begun to develop intensively as a result of the restructuring that is now progressing in the Soviet Union. This is particularly the case with the enterprises and organisations dealing with oil and gas production, all of them component parts of the Ministry of Oil and Gas Industry of the USSR. Owing to the enormous territorial expanse of this country, and also to the rather considerable volume of oil produced, the scheme of organisation of this Ministry is complicated and versatile. This Directory lists all the enterprises and organisations that are component parts of the Ministry, their postal addresses, their telephone numbers and the names of their departmental heads.

The oil and gas equipment and services market in New Zealand

International Nuclear Information System (INIS)

2002-01-01

In terms of petroleum exploration investment, New Zealand ranks seventeenth in the world. The oil, gas, and petrochemical industry is mainly concentrated in Taranaki, a province where considerable onshore and offshore exploration and production (E and P) activity is taking place. The largest licensing round in the petroleum industry of New Zealand was recently completed, with 41 applications emanating from 21 companies were submitted, related to 26 new exploration blocks located onshore and frontier Taranaki basin. Starting in 2007, New Zealand is expected to suffer from a natural gas shortfall due to the gradual depletion of the main natural gas field called Maui. As a result, the development of the Pohokura project is being afforded top priority. In 2002, in the province of Taranaki, it is expected that 125 million dollars will be spent in support of exploration activity. The areas of oil and gas exploration such as seismic surveying services, geophysical services, drilling, monitoring and logging, and field management technologies represent potential opportunities for Canadian companies specialized in the provision of oil and gas equipment and services. For the period 2002-2005, New Zealand is planning significant offshore deep-water E and P projects with a view to ensure a secure supply of natural gas. The largest domestic oil and gas E and P company in New Zealand is Todd Petroleum Mining Company, while the largest foreign-owned oil and gas production company operating in the country is Shell Petroleum Mining Company. Responsible for over 90 per cent of oil and gas production, the largest joint oil service company in New Zealand is Shell Todd Oil Service (STOS), 50 per cent owned by Shell Petroleum Mining Company and 50 per cent by Todd Petroleum Mining Company. Canadian equipment and services might be particularly well received by companies such as STOS and Natural Gas Corporation. Partners in oil and gas projects are sought by companies such as Shell.

The oil and gas equipment and services market in Bolivia

International Nuclear Information System (INIS)

2003-01-01

The economy of Bolivia is based mainly on agriculture and resource extraction, making Bolivia one of the poorest countries in Latin America. Approximately 14 per cent of exports are hydrocarbons. Starting in 1996, the oil and gas sector was privatised, resulting in the domination of multinational corporations. It is estimated that the natural gas reserves of Bolivia stand in excess of 2.2 trillion cubic metres. Equipment, materials, and services used in all stages of the oil and gas production and distribution chain are all in demand in Bolivia. Over the medium term, it is expected that pipelines and equipment required for gas-fired power plants represent the most important opportunity in the country. Incentives for vehicle and industrial conversion were included in the new domestic energy plan, as well as the extension of the domestic gas distribution system to 250,000 homes. Canadian geomatics capability could fill the requirements concerning the Bolivian oil and gas assets still in the exploration, development, and documentation stages. Companies with exploration and development contracts, companies producing from commercial fields, refinery operators, producers in the liquid propane gas and compressed natural gas sub-sector, as well as pipeline operators are all considered key players, in addition to the Bolivian Chamber of Hydrocarbons. The customers are sophisticated buyers who purchase based on technical specifications and price negotiations. There are no significant non-tariff barriers, and Bolivia has adopted liberal trade policies. 9 refs., 3 tabs

Brakstad, Odd Gunnar; Almås, Inger K; Krause, Daniel Franklin

2017-09-01

Field data from the Deepwater Horizon (DWH) oil spill in the Gulf of Mexico (GoM) suggested that oxidation of gas compounds stimulated biodegradation of oil compounds in the deep sea plume. We performed experiments with local seawater from a Norwegian fjord to examine if the presence of dissolved gas compounds (methane, ethane and propane) affected biodegradation of volatile oil compounds, and if oil compounds likewise affected gas compound oxidation. The results from the experiment showed comparable oil compound biotransformation rates in seawater at 5 °C between seawater with and without soluble gases. Gas oxidation was not affected by the presence of volatile oil compounds. Contrary to DWH deep sea plume data, propane oxidation was not faster than methane oxidation. These data may reflect variations between biodegradation of oil and gas in seawater environments with different history of oil and gas exposure. Copyright © 2017 Elsevier Ltd. All rights reserved.

Surface water and groundwater risks associated with unconventional oil and gas development result from potential spills of the large volumes of chemicals stored on-site during drilling and hydraulic fracturing operations, and the return to the surface of significant quantities of saline water produced during oil or gas well production. To better identify and mitigate risks, watershed models and tools are needed to evaluate the dispersion of pollutants in possible spill scenarios. This information may be used to determine the placement of in-stream water-quality monitoring instruments and to develop early-warning systems and emergency plans. A chemical dispersion model has been used to estimate the contaminant signal for in-stream measurements. Spills associated with oil and gas operations were identified within the Susquehanna River Basin Commission’s Remote Water Quality Monitoring Network. The volume of some contaminants was found to be sufficient to affect the water quality of certain drainage areas. The most commonly spilled compounds and expected peak concentrations at monitoring stations were used in laboratory experiments to determine if a signal could be detected and positively identified using standard water-quality monitoring equipment. The results were compared to historical data and baseline observations of water quality parameters, and showed that the chemicals tested do commonly affect water quality parameters. This work is an effort to demonstrate that hydrologic and water quality models may be applied to improve the placement of in-stream water quality monitoring devices. This information may increase the capability of early-warning systems to alert community health and environmental agencies of surface water spills associated with unconventional oil and gas operations.

Investigations of Flare Gas Emissions in Taq Taq Oil Field on the Surrounding Land

Directory of Open Access Journals (Sweden)

Jafar A. Ali

2014-11-01

Full Text Available Environmental pollution caused by oil takes many different forms; one of the most damaging sources is simply the combustion of oil products, such as a well flare burn-off. This paper presents the results of a survey of the agriculture lands around the Taq Taq Oil Production Company. The aim of the survey was to determine the potential contamination caused by the gas emissions from the well flares. Taq Taq field is located in the Kurdistan Region of Iraq, 60 km north of the giant Kirkuk oil field, 85 km south-east of Erbil and 120 km north-west of Suleimani. Samples of soil were collected from several locations around the site and analyzed to determine the content of Polycyclic Aromatic Hydrocarbons PAH present. A gas chromatography linked to a mass spectrometry (GCMS machine was used for these measurements. The PAH contamination at each location of soil was determined and the 16-PAHs, as listed in the US Environmental Protection Agency (EPA documentation were investigated. The average content of total PAH in all samples of the agricultural soil was 0.654 mg·kg-1 with the concentrations ranging from 0.310 to 0.869 mg·kg-1. It was found that the PAH concentrations decreased with increasing distance from the TTOPCO oil field, indicating that pollution was evident, the area close to the field being more affected by the gas pollution.

Oils; gas

Energy Technology Data Exchange (ETDEWEB)

Day, D T

Oils and gas are obtained from shale or oil-bearing sand by immersing the shale in and passing it through a bath of liquid oil, cracking the oil-soaked shale, and condensing the vapor and using the condensate to replenish the bath, preferably by passing the gases and vapors direct into the oil-bath container. Shale is fed continuously from a hopper to a bath of oil in an inclined chamber, is carried to the outlet by a conveyer, and through cracking tubes to an outlet pipe by conveyers. The gases and vapors escape by the pipe, a part condensing in the chamber and a run-back pipe and replenishing the bath, and the remainder passing through a condensing tower and condenser connected to reservoirs; the gas is further passed through a scrubber and a pipe to the burner of the retort. The oil condensed in the chamber overflows to the reservoir through a pipe provided with an open pipe to prevent siphoning. The conveyers and a valve on the pipe are operated by gearing. The operation may be conducted at reduced, normal, or increased pressure, e.g., 70 lbs. The temperature of the retort should be about 900 to 1400/sup 0/F, that of the inside of the tubes about 550 to 700/sup 0/F, and that of the chamber about 300/sup 0/F. The chamber and pipe may be insulated or artificially cooled.

Environmental issues in oil and gas operations in Yukon and in the N.W.T

International Nuclear Information System (INIS)

MacWilliam, A.G.

1999-01-01

Companies planning an expansion into the two territories ought to examine the way each territory deals with potential environmental issues such as spills, releases, contaminated sites and the reclamation of land. Recent legislation has provided each territory with a certain amount of autonomy, which includes the ability to oversee environmental protection. The Yukon, in particular, has considerable freedom in addressing environmental issues relating to oil and gas activities. Both territories are subject to the input and approval of the federal government and First Nations citizens where their respective interests or lands are involved. An overview is included of the regulation of environmental matters north of the 60th parallel. Although the expansion of oil and gas companies into the two territories 'north of 60' offers new opportunities, operators must consider the potential for environmental issues such as spills, releases, site contamination and reclamation of land. In the Yukon where the government has assumed jurisdiction to regulate oil and gas resources, it is implementing a comprehensive regime to deal with environmental issues, at first, in draft form. In contrast, in the N.W.T. the federal government retains considerable control over gas and oil rights and the consequent environmental issues, and, accordingly, it is essential to be aware of federal environmental regulations for the time being

The cyclocraft is a proven hybrid aircraft, capable of VTOL, lifting heavy and bulky loads, highly controllable, having high safety characteristics and low operating costs. Mission Research Corporation (MRC), under Department of Energy sponsorship, is evaluating the potential use of cyclocraft in the transport of drill rigs, mud, pipes and other materials and equipment, in a cost effective and environmentally safe manner, to support oil and gas drilling, production, and transportation operations in wetland areas. Based upon the results of an earlier parametric study, a cyclocraft design, having a payload capacity of 45 tons and designated H.1 Cyclocraft, was selected for further study, including the preparation of a preliminary design and a development plan, and the determination of operating costs. This report contains all of the results derived from the program to evaluate the use of cyclocraft in the support of oil and gas drilling and production operations in wetland areas.

Geologic distributions of US oil and gas

International Nuclear Information System (INIS)

1992-01-01

This publication presents nonproprietary field size distributions that encompass most domestic oil and gas fields at year-end 1989. These data are organized by geologic provinces as defined by the American Association of Petroleum Geologists' Committee on Statistics of Drilling (AAPG/CSD), by regional geographic aggregates of the AAPG/CSD provinces, and Nationally. The report also provides partial volumetric distributions of petroleum liquid and natural gas ultimate recoveries for three macro-geologic variables: principal lithology of the reservoir rock, principal trapping condition and geologic age of the reservoir rock, The former two variables are presented Nationally and by geographic region, in more detail than has heretofore been available. The latter variable is provided Nationally at the same level of detail previously available. Eighteen tables and 66 figures present original data on domestic oil and gas occurrence. Unfortunately, volumetric data inadequacy dictated exclusion of Appalachian region oil and gas fields from the study. All other areas of the United States known to be productive of crude oil or natural gas through year-end 1989, onshore and offshore, were included. It should be noted that none of the results and conclusions would be expected to substantively differ had data for the Appalachian region been available for inclusion in the study

Well-defined performance indicators can motivate optimal operation of offshore oil and gas platforms. This paper aims to develop such parameters, indicating possibilities for reducing power consumption and emissions of pollutants. Different platforms have different oilfield conditions and process...... specifications. Such conditions determine the theoretical minimum work required to operate the platforms, and can have a high impact on the power consumption. We introduce performance indicators based on energy and exergy. The specific energy use and specific exergy consumption evaluate the resources spent...... required under ideal conditions (i.e. reversible operation), and specific exergy destruction illustrates the amount of resources lost due to irreversibilities. We use these indicators to evaluate the oil and gas processing at four different North Sea platforms that differ by the field lifetime, system...

In many countries, human-caused emissions of the two major long lived greenhouse gases, carbon dioxide and methane, are primarily linked to the use of fossil fuels (coal, oil and natural gas). Fugitive emissions of natural gas (mainly CH4) from the oil and gas exploration and production sector may also be an important contributor to natural gas life cycle/greenhouse gas footprint. Fuel use statistics have traditionally been used in combination with fuel and process specific emission factors to estimate CO2 emissions from fossil-fuel-based energy systems (power plants, motor vehicles…). Fugitive emissions of CH4, in contrast, are much harder to quantify. Fugitive emission levels may vary substantially from one oil and gas producing basin to another and may not scale with common activity data, such as production numbers. In the USA, recent efforts by the industry, States and the US Environmental Protection Agency have focused on developing new bottom-up inventory methodologies to assess methane and volatile organic compounds emissions from oil and gas producing basins. The underlying assumptions behind these inventories are multiple and result de facto in large uncertainties. Independent atmospheric-based estimates of emissions provide another valuable piece of information that can be used to evaluate inventories. Over the past year, the NOAA Earth System Research Laboratory has used its expertise in high quality GHG and wind measurements to evaluate regional emissions of methane from two oil and gas basins in the Rocky Mountain region. Results from these two campaigns will be discussed and compared with available inventories.

Oil shale, shale oil, shale gas and non-conventional hydrocarbons

Clerici A.

2015-01-01

Full Text Available In recent years there has been a world “revolution” in the field of unconventional hydrocarbon reserves, which goes by the name of “shale gas”, gas contained inside clay sediments micropores. Shale gas finds particular development in the United States, which are now independent of imports and see a price reduction to less than one third of that in Europe. With the high oil prices, in addition to the non-conventional gas also “oil shales” (fine-grained sedimentary rocks that contain a large amount of organic material to be used both to be directly burned or to extract liquid fuels which go under the name of shale oil, extra heavy oils and bitumen are becoming an industrial reality. Both unconventional gas and oil reserves far exceed in the world the conventional oil and gas reserves, subverting the theory of fossil fuels scarcity. Values and location of these new fossil reserves in different countries and their production by comparison with conventional resources are presented. In view of the clear advantages of unconventional fossil resources, the potential environmental risks associated with their extraction and processing are also highlighted.

This paper describes the evolution of a project that involves cogeneration of power and steam for continuous injection in oil wells in the fields of Alto do Rodrigues and Estreito, in Rio Grande do Norte, Brazil. The project combines a PETROBRAS intention for recovering heavy oil in that area with partners intention of generating power to connect in a critical point of the Brazilian Electric System. PETROBRAS studies began in the nineties, when oil wells in that area became old end showed the necessity of some oil recovery technology. In 1999, PETROBRAS and Guaraniana made a partnership for implementation of Termoacu Combined Cycle, that would begin operation as a cogeneration plant for thirteen years, and as combined cycle from that point. The profile of steam injection has been adapted to a new one to comply with the powe r capacity of the Plant, and will operate eight years as a cogeneration plant , four years as a combined cycle with cogeneration and after twelve years as a complete combined cycle with 500 MW of capacity. The project integrates a gas pipeline, a Thermal Power Plant, a Transmission Line to connect to the grid and a Steam Pipeline for steam injection at Estreito and Alto do Rodrigues fields. (author)

Radioisotope techniques for problem solving in the offshore oil and gas industry

Charlton, J.S.; Hurst, J.A.

1994-01-01

Radioisotope technology has been used for almost half a century by the oil and gas industry to solve problems and to help optimize process operations. The use of radioactive isotopes to investigate the effectiveness of well stimulation procedures and to measure the sweep-out patterns of oil and gas in secondary recovery process is well known. The applications of radioisotopes to study features of plant and process operation has been less widely reported though the economic benefits deriving from such applications are very great. Nevertheless, there has been continuous development in the range of application and in the design of equipment to facilitate the use of the technology at remote environments such as an oil or gas platform. Some indication of the current usage of radioisotope techniques may be obtained from examination of Table I, which lists projects carried out in the UK's North Sea fields by ICI Tracerco, which is the world's largest radioisotope applications service group

This paper studies the current available options for floating production platforms in developing deepwater oil fields and the potential development models of future oil and gas exploration in the South China Sea. A detailed review of current deepwater platforms worldwide was performed through the examples of industry projects, and the pros and cons of each platform are discussed. Four types of platforms are currently used for the deepwater development: tension leg platform, Spar, semi-submersible platform, and the floating production system offloading. Among these, the TLP and Spar can be used for dry tree applications, and have gained popularity in recent years. The dry tree application enables the extension of the drilling application for fixed platforms into floating systems, and greatly reduces the cost and complexity of the subsea operation. Newly built wet tree semi-submersible production platforms for ultra deepwater are also getting their application, mainly due to the much needed payload for deepwater making the conversion of the old drilling semi-submersible platforms impossible. These platforms have been used in different fields around the world for different environments; each has its own advantages and disadvantages. There are many challenges with the successful use of these floating platforms. A lot of lessons have been learned and extensive experience accumulated through the many project applications. Key technologies are being reviewed for the successful use of floating platforms for field development, and potential future development needs are being discussed. Some of the technologies and experience of platform applications can be well used for the development of the South China Sea oil and gas field.

Gas, Oil, and Water Production from Jonah, Pinedale, Greater Wamsutter, and Stagecoach Draw Fields in the Greater Green River Basin, Wyoming

Gas, oil, and water production data were compiled from selected wells in four gas fields in rocks of Late Cretaceous age in southwestern Wyoming. This study is one of a series of reports examining fluid production from tight-gas reservoirs, which are characterized by low permeability, low porosity, and the presence of clay minerals in pore space. Production from each well is represented by two samples spaced five years apart, the first sample typically taken two years after commencement of production. For each producing interval, summary diagrams of oil versus gas and water versus gas production show fluid production rates, the change in rates during five years, the water-gas and oil-gas ratios, and the fluid type. These diagrams permit well-to-well and field-to-field comparisons. Fields producing water at low rates (water dissolved in gas in the reservoir) can be distinguished from fields producing water at moderate or high rates, and the water-gas ratios are quantified. The ranges of first-sample gas rates in Pinedale field and Jonah field are quite similar, and the average gas production rate for the second sample, taken five years later, is about one-half that of the first sample for both fields. Water rates are generally substantially higher in Pinedale than in Jonah, and water-gas ratios in Pinedale are roughly a factor of ten greater in Pinedale than in Jonah. Gas and water production rates from each field are fairly well grouped, indicating that Pinedale and Jonah fields are fairly cohesive gas-water systems. Pinedale field appears to be remarkably uniform in its flow behavior with time. Jonah field, which is internally faulted, exhibits a small spread in first-sample production rates. In the Greater Wamsutter field, gas production from the upper part of the Almond Formation is greater than from the main part of the Almond. Some wells in the main and the combined (upper and main parts) Almond show increases in water production with time, whereas increases

New oil and gas incentives in Saskatchewan

Patel, B.

2003-01-01

Saskatchewan is Canada's second largest producer of crude oil and the third largest producer of natural gas with nearly 400 oil and gas companies operating in the province. The oil ranges from heavy sour to light sweet crude oil. Nearly half of the production is heavy oil, 30 per cent is medium oil and 20 per cent is light oil. In 2002, the Province announced changes to the oil and gas Royalty and Tax Regime in an effort to encourage new oil and gas exploration and development activities in Saskatchewan and to help the industry compete with other jurisdictions around the world. This paper examined the pre-October 2002 Saskatchewan Crown Royalty and freehold production tax structure and compared them to the new structure. The paper also briefly outlined the corporation capital tax, resource surcharge, and flow-through share tax credit initiatives announced in 2001 and 2002. With reductions in the Crown Royalty, freehold production tax and corporation capital taxes, the Province expects that more than 9000 oil and gas wells will be drilled in the next decade, representing new investment of about $4.3 billion and 40,000 new jobs. The flow-through share credit may not attract significant investment because it only benefits those who pay taxes in Saskatchewan. 40 refs

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

The objective of this study is to design, set up and operate an incinerator system capable of providing clean exhaust and safety control for burning oil gas generated during the recovery process of oil spill in Taiwan. In this study, we successfully develop a vertical-type incinerator, which consists of five oil gas burners with entrained primary air, a pilot burner, and an auxiliary burner. The incinerator system is equipped with necessary control units in order to achieve safe, easy, fast, and efficient operation. Flame appearance, flue gas temperature and CO emission of the incinerator system for burning oil gas are reported and discussed. Under the long-term operation, it is found that the new designed incinerator is satisfactory for burning oil gas with low supply pressure at various compositions and supply rates during the recovery process of oil spill. It is noteworthy that the results obtained herein are of great significance to provide a good guidance for those who need to design, set up and operate an incinerator system providing clean exhaust and safety control for burning oil gas generated during the recovery process of oil spill in a polluted site with a large area.

Peak oil and gas

Ziegler, W. H.; Campbell, C. J.; Zagar, J.J.

Oil and gas were formed under exceptional conditions in the geological past, meaning that they are subject to natural depletion, such that the past growth in production must give way to decline. Although depletion is a simple concept to grasp, public data on the resource base are extremely unreliable due to ambiguous definitions and lax reporting. The oil industry is reluctant to admit to an onset of decline carrying obvious adverse financial consequences. There are several different categories of oil and gas, from tar sands to deep water fields, each with specific characteristics that need to be evaluated. It is important to build a global model on a country by country basis in order that anomalous statistics may be identified and evaluated. Such a study suggests that the world faces the onset of decline, with far-reaching consequences given the central role of oil-based energy. It is accordingly an important subject deserving detailed consideration by policy makers. (author)

The features of oil & gas complex's strategic management and hydrocarbon products transportation at developing marine oil & gas fields in Arctic

Directory of Open Access Journals (Sweden)

2017-12-01

Full Text Available The paper considers some theoretical and practical issues of strategic management of oil and gas complex at the development of hydrocarbon resources in the Arctic offshore. The analysis of existing approaches in process and project management of oil and gas complex has been carried out taking into account characteristics of offshore projects in the Arctic zone. Considerable attention has been paid to the history and evolution of strategic management as an economic category, functional areas of strategic management at different levels of management have been proposed. The analysis of existing scientific works dedicated to the projects on the Arctic shelf, has shown insufficient development of the strategic management's theory and practice. In particular, the biggest part of the scientific studies is focused on studying issues of the management at the corporate level, at the same time questions at the level of the oil and gas complex are not considered. In existing studies, the project and process approaches to management are often opposed to each other, and according to the authors it is incorrect in relation to the management of the oil and gas complex on the Arctic shelf. The oil and gas complex is a complex and multilevel system that implements unprecedentedly difficult projects in terms of technology. The beginning of hydrocarbon production on the Arctic shelf is inextricably linked with the transportation of extracted raw materials to the processing and marketing sites; it complements the strategic management of the oil and gas complex by the features of organizing efficient transport and logistics solutions.

Emissions from oil and gas operations in the United States and their air quality implications.

Science.gov (United States)

Allen, David T

2016-06-01

The energy supply infrastructure in the United States has been changing dramatically over the past decade. Increased production of oil and natural gas, particularly from shale resources using horizontal drilling and hydraulic fracturing, made the United States the world's largest producer of oil and natural gas in 2014. This review examines air quality impacts, specifically, changes in greenhouse gas, criteria air pollutant, and air toxics emissions from oil and gas production activities that are a result of these changes in energy supplies and use. National emission inventories indicate that volatile organic compound (VOC) and nitrogen oxide (NOx) emissions from oil and gas supply chains in the United States have been increasing significantly, whereas emission inventories for greenhouse gases have seen slight declines over the past decade. These emission inventories are based on counts of equipment and operational activities (activity factors), multiplied by average emission factors, and therefore are subject to uncertainties in these factors. Although uncertainties associated with activity data and missing emission source types can be significant, multiple recent measurement studies indicate that the greatest uncertainties are associated with emission factors. In many source categories, small groups of devices or sites, referred to as super-emitters, contribute a large fraction of emissions. When super-emitters are accounted for, multiple measurement approaches, at multiple scales, produce similar results for estimated emissions. Challenges moving forward include identifying super-emitters and reducing their emission magnitudes. Work done to date suggests that both equipment malfunction and operational practices can be important. Finally, although most of this review focuses on emissions from energy supply infrastructures, the regional air quality implications of some coupled energy production and use scenarios are examined. These case studies suggest that both

Full Text Available Since the “Tenth Five-Year Plan”, lithologic and stratigraphic reservoirs have been the main contribution of both the discovery as well as reserve and production increase in China; there were about 80% of proven reserves. The typical reservoirs in six major basins in the eastern, central, and western China were adopted as reservoir forming models. The reservoir forming models in three types of slopes, three types of depressions, and three types of lithologic reservoir assemblages have been built on the basis of application of new technologies, physical modeling of reservoir forming mechanism, and investigation to the formation and distribution of the reservoirs. The evaluation methods for large lithologic reservoirs provinces were established based on the forming mechanism and main controlling factors mentioned above. In addition, the study reveals the main controlling factors and the laws of enrichment of two types of stratigraphic reservoirs (pinch-out and weathered karst reservoirs based on the evaluation methods for large stratigraphic reservoir provinces that have been established. By comprehensively understanding the laws of enrichment of lithologic-stratigraphic reservoirs in four types of basins, specific evaluation methods and fine exploration techniques have been developed. The findings led to an exploration direction in the “Thirteenth Five-Year Plan” period. The study supported the exploration and selection of oil and gas plays, as well as promoted the exploration of lithologic and stratigraphic reservoirs.

Based on a study of the characteristics of product flows from oil wells, the test and monitoring equipment used to monitor the quantity of oil, and the standard documentation, it is demonstrated that in order to increase the measurement accuracy of the product produced by the oil and gas production administration, it is necessary to develop a system of enterprise standards to account for it. A list is given of standards of use by oil and gas production administration to account for its product. The use of the standards with existing metering equipment makes it possible to decrease the variation between operational and inventory records for the quantity of oil at the ''Rechitsaneft'' oil and gas production administration up to 5% and consequently to increase the control efficiency over the operation of the fields.

Energy efficiency measures for offshore oil and gas platforms

International Nuclear Information System (INIS)

Nguyen, Tuong-Van; Voldsund, Mari; Breuhaus, Peter; Elmegaard, Brian

2016-01-01

Oil and gas platforms are energy-intensive systems – each facility uses from a few to several hundreds MW of energy, depending on the petroleum properties, export specifications and field lifetime. Several technologies for increasing the energy efficiency of these plants are investigated in this work. They include: (i) the installation of multiple pressure levels in production manifolds, (ii) the implementation of multiphase expanders, (iii) the promotion of energy and process integration, (iv) the limitation of gas recirculation around the compressors, (v) the exploitation of low-temperature heat from the gas cooling steps, (vi) the downsizing or replacement of the existing gas turbines, and (vii) the use of the waste heat from the power plant. The present study builds on four actual cases located in the North and Norwegian Seas, which differ by the type of oil processed, operating conditions and strategies. The benefits and practical limitations of each measure are discussed based on thermodynamic, economic and environmental factors. Significant energy savings and reductions in CO_2-emissions are depicted, reaching up to 15–20%. However, they strongly differ from one facility to another, which suggests that generic improvements can hardly be proposed, and that thorough techno-economic analyses should be conducted for each plant. - Highlights: • Energy efficiency measures for offshore platforms are assessed. • Energy savings and reductions in CO_2-emissions can reach up to 15-20%. • They differ strongly depending on the oil type, operating conditions and strategies.

Canadian oil and gas survey 1998

Roberge, R.B.

1998-01-01

The year 1997 brought record levels of financing for the Canadian oil and gas industry which led to record levels of capital spending and unprecedented merger and acquisition activity. Production records were achieved, but soft commodity prices in the fourth quarter resulted in a significant downturn in the equity markets. El Nino reduced demand for natural gas and heating oil, resulting in increased storage levels for both commodities. Record drilling and capital spending fueled the Canadian oilfield service industry as total market capitalization rose to $10 billion. As for the 1998 outlook, the industry has turned to natural gas as the favoured commodity, as indicated by the conclusion of the Alliance pipeline hearings and the Nova/TCPL merger. This survey presents a review of crude oil and natural gas production, prices, and capital spending for development and exploratory wells, and the financial and operating results for fiscal year 1997 of selected oil and gas companies and income trusts. All listed companies are Canadian public companies, or publicly traded income trusts, traded on one of the country's four major stock exchanges. They are ranked according to gross oil and gas production revenue only (before royalties). Syncrude and oil sands production is also included. The remaining data in the financial statistics tables includes all business segments of each company included. The survey excluded companies that were wholly-owned subsidiaries, divisions or U.S. subsidiaries and private companies. tabs., figs

To date, many of the 47 exploration and development wells drilled in the Ogaden Basin in Ethiopia have exhibited natural oil seeps and oil and gas shows. The Calub gas field and the Hilala oil field occurs in the central part of the 350,000 sq. km. basin. The various units within the basin consist of continental sediments, a regional organic-rich interval close to the Permo-Triassic boundary, organic-rich marine sediments and carbonates. The Ogaden Basin is dissected by several faults that are related to the Ethiopian Rift and may form a component of traps in the Calub-Hilala area.

The impact of energy production on the atmosphere: Laboratory and field studies of emissions from oil and gas production and their chemical transformation

Science.gov (United States)

Li, Rui

Over the past decades, the rapid development of energy production in the U.S. has led to significant changes in atmospheric emissions and transformation of trace gas and particles, which are still very uncertain and poorly understood. Through laboratory, modeling and field experiments we hope to better understand the trace gas emission and their contribution to secondary organic aerosols (SOA) formation in the oil and natural gas (O&NG) operations. A fast time-response Oxidation Flow Reactor (OFR) is used for the study of SOA formation from oil vapors. The radical chemistry and quantification of OH exposure (OHexp) in the reactor under various conditions were investigated using a photochemical kinetic model. An OHexp estimation equation derived from the model was shown to agree with measurements in several field campaigns. This work further establishes the usefulness of such reactors in atmospheric studies. Motivated from the SOA observations of Gulf of Mexico oil spill, the SOA formation from organic compounds of different volatility in the oil vapors was studied in the laboratory using OFR. We use the evaporation time dependence on volatility of the precursors to quantify their contribution to total SOA formation. This study shows (1) organic compounds of intermediate volatility contribute the large majority of SOA mass formed, (2) the mass spectral signature of SOA shows good agreement with that of ambient SOA formed during oil spill. These results in O&NG operations, the air toxic hydrogen sulfide (H 2S) can be released at wellheads, separation and storage tanks. Here, quantitative, fast time-response measurements of H2S using Proton-Transfer-Reaction Mass-Spectrometry (PTR-MS) instruments in an O&NG field are presented. A laboratory calibration study was performed to measure the humidity dependent sensitivities of H2S. The close correlation between H2S and CH4 and significant H2S levels downwind of storage tanks suggest that H2S emissions associated with O

There is a significant amount of financial risk associated with geothermal drilling; however, there are opportunities to improve upon current practices and technologies used. The scope of this drilling operational study included 21 geothermal wells and 21 oil and gas wells. The goal was to determine a 'perfect well' using historical data to compare the best oil and gas well to the best geothermal well. Unfortunately, limitations encountered in the study included missing data (bit records, mud information, etc.), poor data collection, and difficult to ascertain handwriting. An online software database was used to format drilling data to IADC coded daily drilling reports and generate analysis figures. Six major issues have been found in geothermal drilling operations. These problems include lost circulation, rig/equipment selection, cementing, penetration rate, drilling program, and time management. As a result of these issues, geothermal drilling averages 56.4 days longer than drilling comparable oil and gas wells in the wells in this study. Roughly $13.9 million would be lost due to non-productive time in the 21 geothermal wells and only $1.3 million in the oil and gas wells, assuming a cost of $50,000 per day. Comparable events such as drilling the same sized hole, tripping in/out, cementing, and running the same size casing took substantially less time in the oil and gas wells. Geothermal wells were drilled using older and/or less advanced technology to depths less than 10,000 feet, while oil and gas wells reached 12,500 feet faster with purpose built rigs. A new approach is now underway that will optimize drilling programs throughout the drilling industry. It is the use of Mechanical Specific Energy (MSE) as a tool to realize efficient drilling processes. However, a work-flow must also be established in order for there to be an efficient drilling program. Potential improvements for current geothermal operations are: the use of electronic records, real

There is a significant amount of financial risk associated with geothermal drilling. This study of drilling operations seeks opportunities to improve upon current practices and technologies. The scope of this study included analyzing 21 geothermal wells and 21 oil and gas wells. The goal was to determine a 'Perfect Well' using historical data to compare the best oil and gas well to the best geothermal well. Unfortunately, limitations encountered in the study included missing data (bit records, mud information, etc.) and poor data collection practices An online software database was used to format drilling data to IADC coded daily drilling reports and generate figures for analysis. Six major issues have been found in geothermal drilling operations. These problems include lost circulation, rig/ equipment selection, cementing, penetration rate, drilling program, and time management. As a result of these issues, geothermal drilling averaged 56.4 days longer than drilling comparable oil and gas wells in the wells in this study. Roughly $13.9 million was spent on non-productive time in the 21 geothermal wells, compared with only $1.3 million in the oil and gas wells, assuming a cost of $50,000 per day. Comparable events such as drilling the same sized hole, tripping in/out, cementing, and running the same size casing took substantially less time in the oil and gas wells. Geothermal wells were drilled using older and/or less advanced technology to depths less than 10,000 feet, while oil and gas wells reached 12,500 feet faster with purpose built rigs. A new approach is now underway that will optimize drilling programs throughout the drilling industry using Mechanical Specific Energy (MSE) as a tool to realize efficient drilling processes. Potential improvements for current geothermal operations are: the use of electronic records, real time services, and official glossary terms to describe rig operations, and advanced drilling rigs/technology.

This article presents a synthesis of the fast advances in micro co-generation technology and their possible applications in fields of petroleum. The subject is focus of a research of the authors and the preliminary results indicate a potential of contributing for the optimization of mature fields of heavy oil. In general, this technology involves smaller environmental impact and produces better efficiency in those uses that require heat and electricity. An application interesting it is the use of gas micro-turbines, operating in co-generation in a (heavy) oil fields onshore, where it is possible increment of the production to the if it uses the steam injection as method of secondary recovery. The idea of using the heat to improve the productivity of the wells and to increase the recovery factor is almost as old as the industry of the petroleum. The technique consists of heating up the oil to reduce his/her viscosity and to facilitate the drainage. Nowadays, the use of the steam injection is usual in fields of heavy oils (degree API <20), high viscosity (> 500 cp), reservoirs no deep (<1300 m) and net pay in the interval from 5 to 50 m. The innovation, here, is the use of a group of micro-turbines moved to gas (no rare, burned in the flare) to generate the steam 'in loco' (near to the well) and electricity for own consumption or even commercialization. This article presents a case study of the economical potential the use of four gas micro-turbines, operating in micro cogeneration, in a field of 6,6 km{sup 2} in the Brazilian Northeast. (author)

Alaskan North Slope Oil & Gas Transportation Support

Lilly, Michael Russell [Geo-Watersheds Scientific LLC, Fairbanks, AK (United States)

2017-03-31

North Slope oil and gas resources are a critical part of US energy supplies and their development is facing a period of new growth to meet increasing national energy needs. While this growth is taking place in areas active in development for more than 20 years, there are many increasing environmental challenges facing industry and management agencies. A majority of all exploration and development activities, pipeline maintenance and other field support activities take place in the middle of winter, when the fragile tundra surface is more stable. The window for the critical oil and gas winter operational season has been steadily decreasing over the last 25 years. The number of companies working on the North Slope is increasing. Many of these companies are smaller and working with fewer resources than the current major companies. The winter operations season starts with the tundra-travel opening, which requires 15 cm of snow on the land surface in the coastal management areas and 23 cm in the foothills management areas. All state managed areas require -5°C soil temperatures at a soil depth of 30 cm. Currently there are no methods to forecast this opening date, so field mobilization efforts are dependent on agency personnel visiting field sites to measure snow and soil temperature conditions. Weeks can be easily lost in the winter operating season due to delays in field verification of tundra conditions and the resulting mobilization. After the season is open, a significant percentage of exploration, construction, and maintenance do not proceed until ice roads and pads can be built. This effort is dependent on access to lake ice and under-ice water. Ice chipping is a common ice-road construction technique used to build faster and stronger ice roads. Seasonal variability in water availability and permitting approaches are a constant constraint to industry. At the end of the winter season, projects reliant on ice-road networks are often faced with ending operations

Market potential of solar thermal enhanced oil recovery-a techno-economic model for Issaran oil field in Egypt

Science.gov (United States)

Gupta, Sunay; Guédez, Rafael; Laumert, Björn

2017-06-01

Solar thermal enhanced oil recovery (S-EOR) is an advanced technique of using concentrated solar power (CSP) technology to generate steam and recover oil from maturing oil reservoirs. The generated steam is injected at high pressure and temperature into the reservoir wells to facilitate oil production. There are three common methods of steam injection in enhanced oil recovery - continuous steam injection, cyclic steam stimulation (CSS) and steam assisted gravity drainage (SAGD). Conventionally, this steam is generated through natural gas (NG) fired boilers with associated greenhouse gas emissions. However, pilot projects in the USA (Coalinga, California) and Oman (Miraah, Amal) demonstrated the use of S-EOR to meet their steam requirements despite the intermittent nature of solar irradiation. Hence, conventional steam based EOR projects under the Sunbelt region can benefit from S-EOR with reduced operational expenditure (OPEX) and increased profitability in the long term, even with the initial investment required for solar equipment. S-EOR can be realized as an opportunity for countries not owning any natural gas resources to make them less energy dependent and less sensible to gas price fluctuations, and for countries owning natural gas resources to reduce their gas consumption and export it for a higher margin. In this study, firstly, the market potential of S-EOR was investigated worldwide by covering some of the major ongoing steam based EOR projects as well as future projects in pipeline. A multi-criteria analysis was performed to compare local conditions and requirements of all the oil fields based on a defined set of parameters. Secondly, a modelling approach for S-EOR was designed to identify cost reduction opportunities and optimum solar integration techniques, and the Issaran oil field in Egypt was selected for a case study to substantiate the approach. This modelling approach can be consulted to develop S-EOR projects for any steam flooding based oil

2013-06-01

Oil has been one of the main energy sources in Turkey, accounting for some 28% of the country’s total primary energy supply (TPES) in 2011. Turkey’s oil demand slightly increased from 637 kb/d in 2003 to 670 kb/d in 2012, although it dropped down from 678 kb/d in 2009 to 650 kb/d in 2010. The transport sector accounted for half of total oil consumption in 2010. Domestic oil production is in decline in Turkey, amounting to 45 kb/d or about 6.7% of total consumption in 2012. In 2012, Turkey imported 712 kb/d, consisting of about 392 kb/d of crude oil and some 320 kb/d refined products. Around 39% of total crude oil imports came from Iran. Crude oil and petroleum products are mainly undertaken by tankers and two major international pipelines running through the country with a total annual handling capacity of 2.8 mb/d. In the country, there are four operational refineries with a total crude distillation capacity of around 610 kb/d. Turkey meets its 90-day stockholding obligation to the IEA by placing a minimum stockholding obligation on industry. Under the relevant acts, refineries and fuel distribution companies are obliged to hold at least 20 days of product stocks based on the average daily sales of previous year, while eligible consumers that use more than 20,000 tonnes annually are required to hold 15 days’ consumption of each type of liquid fuel. Turkey held some 61 million barrels of oil stocks at the end of January 2013, equating to 99 days of 2011 net-imports. Around 55% of total oil stocks are held in the form of crude oil. The use of emergency oil stocks is central to Turkey’s emergency response policy, which can be complemented by demand restraint measures. The share of natural gas in the country’s TPES significantly increased at 32% in 2011. Turkey’s gas demand significantly increased from 0.7 billion cubic meters (2 mcm/d) in 1987 to 45.3 bcm (124 mcm/d) in 2012, while indigenous natural gas production totalled some 0.63 bcm in the same year

This paper reports on the development of Tambora and Tunu gas fields in Kalimantan that have increased available gas supply for the export of liquefied natural gas (LNG) from Indonesia. The demand for LNG is increasing in the energy thirsty Far East market. And Indonesia, the world's largest exporter, is keeping pace by expanding the Bontang liquefaction plant in East Kalimantan. A fifth train, with a capacity of around 2.5 million tons/year, began operating in January 1990. Start-up of a sixth train, of identical capacity, is planned for January 1994. The Bontang plant is operated by PT Badak on behalf of Pertamina, the Indonesian state oil and gas mining company. The feed to the fifth train comes primarily from the first-phase development of Total Indonesie's two gas fields, Tambora and Tunu. The sixth train will be fed by a second-phase development of the Tunu field

California currently ranks third in oil production by U.S. state and more than 200,000 wells have been drilled in the state. Oil and gas wells provide a potential pathway for subsurface migration, leading to groundwater contamination and emissions of methane and other fluids to the atmosphere. Here we compile available public databases on oil and gas wells from the California Department of Conservation's Division of Oil, Gas, and Geothermal Resources, the U.S. Geological Survey, and other state and federal sources. We perform geospatial analysis at the county and field levels to characterize depths, producing formations, spud/completion/abandonment dates, land cover, population, and land ownership of active, idle, buried, abandoned, and plugged wells in California. The compiled database is designed to serve as a quantitative platform for developing field-based groundwater and air emission monitoring plans.

Sandia's Geothermal Advanced Drill Rig Instrumentation Assists Critical Oil and Gas Drilling Operation

Staller, George E.; Whitlow, Gary

1999-01-01

On November 23, 1998, an 18,000-foot-deep wild-cat natural gas well being drilled near Bakersfield, CA blew out and caught fire. All attempts to kill this well failed, and the well continues to flow under limited control, producing large volumes of natural gas, salt water, and some oil. The oil and some of the water is being separated and trucked off site, and the remaining gas and water is being burned at the well head. A relief well is being drilled approximately one-quarter mile away in an attempt to intercept the first well. If the relief well is successful, it will be used to cement in and kill the first well. Epoch Wellsite Services, Inc., the mud-logging company for the initial well and the relief well, requested Sandia's rolling float meter (RFM) for these critical drilling operations. The RFM is being used to measure the mud outflow rate and detect kicks while drilling the relief well, which will undoubtedly encounter reservoir conditions similar to those responsible for the blow out. Based on its prior experience with the RFM, Epoch believes that it is the only instrument capable of providing the level of accuracy and response to mudflow needed to quickly detect kicks and minimize the risk of a blowout on this second critical well. In response to the urgent request from industry, Sandia and Epoch technicians installed the RFM on the relief well return line, and completed its initial calibration. The data from the RFM is displayed in real-time for the driller, the companyman, and the toolpusher via Epochs RIGWATCH Drilling Instmmentation System. The RFM has already detected several small kicks while drilling toward the annulus of the blown out well. A conventional paddle meter is located downstream of the RFM to provide redundancy and the opportunity to compare the two meters in an actual drilling operation, The relief well is nearing 14,000 feet deep, targeting an intercept of the first well near 17,600 feet. The relief well is expected to be completed in

Gan, Wei; Frohlich, Cliff

2013-11-19

Between 1957 and 1982, water flooding was conducted to improve petroleum production in the Cogdell oil field north of Snyder, TX, and a contemporary analysis concluded this induced earthquakes that occurred between 1975 and 1982. The National Earthquake Information Center detected no further activity between 1983 and 2005, but between 2006 and 2011 reported 18 earthquakes having magnitudes 3 and greater. To investigate these earthquakes, we analyzed data recorded by six temporary seismograph stations deployed by the USArray program, and identified 93 well-recorded earthquakes occurring between March 2009 and December 2010. Relocation with a double-difference method shows that most earthquakes occurred within several northeast-southwest-trending linear clusters, with trends corresponding to nodal planes of regional focal mechanisms, possibly indicating the presence of previously unidentified faults. We have evaluated data concerning injection and extraction of oil, water, and gas in the Cogdell field. Water injection cannot explain the 2006-2011 earthquakes, especially as net volumes (injection minus extraction) are significantly less than in the 1957-1982 period. However, since 2004 significant volumes of gases including supercritical CO2 have been injected into the Cogdell field. The timing of gas injection suggests it may have contributed to triggering the recent seismic activity. If so, this represents an instance where gas injection has triggered earthquakes having magnitudes 3 and larger. Further modeling studies may help evaluate recent assertions suggesting significant risks accompany large-scale carbon capture and storage as a strategy for managing climate change.

2017-12-01

We have measured gas and oil flow through laboratory samples that represent two important potential flow paths in wellbores associated with the Strategic Petroleum Reserve (SPR): cement-steel interfaces (microannuli) and cement fractures. Cement fractures were created by tensile splitting of cement cores. Samples to represent microannuli were created by placing thin steel sheets within split cement cores so flow is channeled along the cement-steel interface. The test sequence included alternating gas and oil flow measurements. The test fluids were nitrogen and silicone oil with properties similar to a typical crude oil stored in the SPR. After correcting for non-linear (inertial) flow when necessary, flows were interpreted as effective permeability and hydraulic aperture using the cubic law. For both samples with cement fractures and those with cement-steel interfaces, initial gas and oil permeabilities were comparable. Once saturated with oil, a displacement pressure had to be overcome to establish gas flow through a sample, and the subsequent gas permeability were reduced by more than 50% compared to its initial value. Keywords: wellbore integrity, leakage, fracture, microannulus, SPR.

Field experiments with subsurface releases of oil and and dyed water

Rye, H.; Brandvik, P.J.; Strom, T.

1998-01-01

A field experiment with a subsurface release of oil and air was carried out in June 1996 close to the Frigg Field in the North Sea area. One of the purposes of this sea trial was to increase the knowledge concerning the behaviour of the oil and gas during a subsurface blowout. This was done by releasing oil and air at 106 meters depth with a realistic gas oil ratio (GOR=67) and release velocity of the oil. In addition to the oil release, several releases with dyed water and gas (GOR=7 - 65) were performed. Important and unique data were collected during these subsurface releases. In particular, the experiments with the dyed water releases combined with air turned out to be an efficient way of obtaining field data for the behaviour of subsurface plumes. The main conclusions from analysis for the data collected are: the field methodology used to study blowout releases in the field appears to be appropriate. The use of dyed water to determine the performance of the subsurface plume proved out to be an efficient way to obtain reliable and useful data. The behaviour of the subsurface plume is very sensitive to gas flow rates. For low gas flow rates, the plume did not reach the sea surface at all due to the presence of stratification in the ambient water. Some discrepancies were found between a numerical model for subsurface releases and field results. These discrepancies are pointed out, and recommendations for possible model improvements are given.

To understand the current state of U.S. greenhouse gas emissions from oil and gas operations, policy makers refer to national inventories and reporting programs, and therefore, it is imperative that these reports are accurate and representative. Many studies exist that investigate the reliability of current monitoring methods, however, to our knowledge the temporal variability of the magnitude and source of methane (CH4) emissions from oil and gas facilities has not been reported in the literature. We present results from a field campaign conducted in June 2014 in the Eagle Ford basin, Texas to assess the temporal variability of emissions from a variety of facilities using data obtained through four different methods. The variability of total CH4 emission rate from individual facilities was investigated by repeated measurement of emissions from five gathering facilities using two aircraft-based mass balance approaches. Basin-wide emissions variation was examined by conducting a series of eight four hour afternoon aerial surveys of two 35 x 35 km areas, with transects oriented perpendicular to the prevailing wind direction. The emission source-type and magnitude were further investigated using helicopter-based FLIR camera observations conducted repeatedly at eight oil wells, one gas well, and four gathering facilities. Results indicate a high degree of variability in day-to-day and sometimes hour-to-hour CH4 emissions magnitude. FLIR camera observations suggest that the component-level source of facility emissions is also highly variable over time, with both storage tank vent stacks and tank hatches representing important components of the observed day-to-day variability. While some emissions were due to scheduled maintenance, others appeared to occur due to faulty and/or aging equipment. Here we discuss what was learned in terms of factors that explain the observed emission rate variability.

Oil and gas site contamination risks : improved oversight needed

International Nuclear Information System (INIS)

2010-02-01

British Columbia has seen record levels of activities in the oil and gas sector. Upstream petroleum processes include exploration, well completion and production. Site contamination can occur during all of these activities, resulting in potential environmental and human health impacts. Although well operators are responsible by law for site restoration, there is a potential risk that some operators will not fulfill their responsibilities, thereby leaving the province liable for the site restoration costs. In British Columbia, the BC Oil and Gas Commission (OGC) is responsible for managing these risks through oversight activities designed to ensure that industry meets its obligations. The OGC also manages the orphan sites reclamation fund. This report presented an audit of the OGC in order to determine if it is providing adequate oversight of upstream oil and gas site contamination risks. The audit examined whether the agency responsibilities are clear and whether the OGC is fully aware of the environmental and financial risks associated with upstream oil and gas site contamination. The audit also examined if the OGC has established appropriate procedures to oversee the risks and to inform the public of how effectively site contamination risks are being managed. The report presented the audit background, audit expectations, findings, conclusions and recommendations. It was concluded that the OGC's oversight of the environmental and financial risks associated with oil and gas site contamination needs improving. tabs., figs.

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.

Sodium-carboxymethylcellulose and arabinogalactane inhibits the crystallization of calcium carbonate from a supersaturated aqueous solution at 80°C. The sizes of formed crystals CaCO3 in the presence of arabinogalactane, sodium-carboxymethylcellulose and neonol AF 9-10 decrease on an average 7-12 μm and a change of their structure. It is expected, that the mechanism of inhibitionis in specific adsorption polysaccharides and neonol on occurring crystalline surface of the calcium carbonate, both at the expense of electrostatic interaction of functional groups with Ca2+ ions, located on the surface of the crystal, and due to coordination and hydrogen bonds with oxygen atoms and HO-groups of additives. Oil-water emulsion rheology in the presence of neonol AF 9-10 has been studied. It is shown that neonol AF 9-10 decrease viscosity natural water-oil emulsion by 25 times. Addition of 5% neonol to water-oil emulsion leads to formation more than 20 stable emulsion forms of different density and composition. New highly effective “green” oilfield reagents have been developed on the basis of neonol and natural polysaccharides.

1966-01-01

Hysteresis behavior of gas-condensate mixtures was studied with a PVT apparatus. The study was conducted at 26 and 80/sup 0/C, with recombined samples having gas factors of 3,000, 6,500, and 10,000 cu meters per ton. Pressure on samples was decreased or increased at rates of 0.2; 0.1; 0.05; and 0.025 atm per sec. Composition of gas- condensate is given. It is reported that different amounts of liquid were produced by condensation and evaporation processes, i.e., results depended on whether pressure was being increased or decreased. It is suggested that the effect of hysteresis should be considered in operation of gas-condensate fields.

Primary inputs into the model include all the publicity available information on currently producing fields relating to their historic and expected production rates, investment, operating and abandonment costs. Information has also been gathered on all new discoveries which have not yet been developed and estimates made of the timing of their development, the commencement of production and costs. Three oil price scenarios base, low and high, have been used in the analysis which extends to the year 2015. The results are presented for two major regions, the central and northern waters and the Southern Gas Basin, including the Irish Sea. Very large numbers of discovered but undeveloped oil and gas fields exist in the UK continental shelf substantial numbers of which could be developed in the event of a very modest real growth in oil and gas prices. The considerable sensitivity of development to movements in oil prices is brought out by the analysis of the three scenarios. (UK)

Eos modeling and reservoir simulation study of bakken gas injection improved oil recovery in the elm coulee field, Montana

Science.gov (United States)

Pu, Wanli

The Bakken Formation in the Williston Basin is one of the most productive liquid-rich unconventional plays. The Bakken Formation is divided into three members, and the Middle Bakken Member is the primary target for horizontal wellbore landing and hydraulic fracturing because of its better rock properties. Even with this new technology, the primary recovery factor is believed to be only around 10%. This study is to evaluate various gas injection EOR methods to try to improve on that low recovery factor of 10%. In this study, the Elm Coulee Oil Field in the Williston Basin was selected as the area of interest. Static reservoir models featuring the rock property heterogeneity of the Middle Bakken Member were built, and fluid property models were built based on Bakken reservoir fluid sample PVT data. By employing both compositional model simulation and Todd-Longstaff solvent model simulation methods, miscible gas injections were simulated and the simulations speculated that oil recovery increased by 10% to 20% of OOIP in 30 years. The compositional simulations yielded lower oil recovery compared to the solvent model simulations. Compared to the homogeneous model, the reservoir model featuring rock property heterogeneity in the vertical direction resulted in slightly better oil recovery, but with earlier CO2 break-through and larger CO2 production, suggesting that rock property heterogeneity is an important property for modeling because it has a big effect on the simulation results. Long hydraulic fractures shortened CO2 break-through time greatly and increased CO 2 production. Water-alternating-gas injection schemes and injection-alternating-shut-in schemes can provide more options for gas injection EOR projects, especially for gas production management. Compared to CO2 injection, separator gas injection yielded slightly better oil recovery, meaning separator gas could be a good candidate for gas injection EOR; lean gas generated the worst results.

Impact of sustained low oil prices on China's oil & gas industry system and coping strategies

Directory of Open Access Journals (Sweden)

Jianjun Chen

Full Text Available The global sustained low oil prices have a significant impact on China's oil and gas industry system and the national energy security. This paper aims to find solutions in order to guarantee the smooth development of China's oil and gas industry system and its survival in such a severe environment. First, the origins of sustained low oil prices were analyzed. Then, based on those published data from IEA, government and some other authorities, this study focused on the development status, energy policies and the future developing trend of those main oil & gas producing countries. Investigations show that the low-price running is primarily contributed to the so-called oil and gas policies in the USA. It is predicted that national petroleum consumption will reach up to 6.0 × 108 t (oil & 3300 × 108 m3 (gas in 2020 and 6.8 × 108 t (oil & 5200 × 108 m3 (gas in 2030. For reducing the dependence on foreign oil and gas, the investment in the upstream of oil and gas industry should be maintained and scientific research should be intensified to ensure the smooth operation of the oil and gas production system. Considering China's national energy security strategy, the following suggestions were proposed herein. First, ensure that in China the yearly oil output reaches 2 × 108 t, while natural gas yield will be expected to be up to 2700 × 108 m3 in 2030, both of which should become the “bottom line” in the long term. Second, focus on the planning of upstream business with insistence on risk exploration investment, scientific and technological innovation and pilot area construction especially for low-permeability tight oil & gas, shale oil & gas reservoir development techniques. Third, encourage the in-depth reform and further growth especially in the three major state-owned oil & gas companies under adverse situations, and create more companies competent to offer overseas technical services by taking the opportunity of the �

Interest grows in African oil and gas opportunities

Knott, D.

1997-01-01

As African countries continue a slow drift towards democratic government and market economics, the continent is increasingly attractive to international oil and gas companies. Though Africa remains politically diverse, and its volatile politics remains a major barrier to petroleum companies, a number of recent developments reflect its growing significance for the industry. Among recent projects and events reflecting changes in Africa: oil and gas exporter Algeria has invited foreign oil companies to help develop major gas discoveries, with a view to boosting exports to Europe; oil and gas producer Egypt invited foreign companies to explore in the Nile Delta region, and the result appears to be a flowering world scale gas play; west African offshore exploration has entered deep water and new areas, and a number of major projects are expected in years to come; Nigeria's reputation as a difficult place to operate has been justified by recent political and civil events, but a long-planned liquefied natural gas (LNG) export plant is being built there; South Africa, which has returned to the international scene after years of trade isolation because of apartheid, is emerging as a potential driver for energy industry schemes throughout the continent. Activities are discussed

Procedures and results of investigations concerning the oiling of inland raptors, migratory water-fowl and other birds are presented. Freon washings from the oiled birds and oil from the pits were analyzed by gas chromatography. In most instances the source of the oil could be established by chromatographic procedures. The numbers of birds involved (including many on the endangered species list) suggested the need for netting or closing oil field waste pits and mud disposal pits. Maintaining a proper chain of custody was important

Gas pressure from a nuclear explosion in oil shale

International Nuclear Information System (INIS)

Taylor, R.W.

1975-01-01

The quantity of gas and the gas pressure resulting from a nuclear explosion in oil shale is estimated. These estimates are based on the thermal history of the rock during and after the explosion and the amount of gas that oil shale releases when heated. It is estimated that for oil shale containing less than a few percent of kerogen the gas pressure will be lower than the hydrostatic pressure. A field program to determine the effects of nuclear explosions in rocks that simulate the unique features of oil shale is recommended. (U.S.)

Oil and gas fiscal regimes of the western Canadian provinces

International Nuclear Information System (INIS)

1991-11-01

This report compares the fiscal regimes in British Columbia, Alberta, Saskatchewan and Manitoba. During 1985-1988, federal and provincial governments have made numerous fiscal changes, many in response to the drop in world oil prices. The new fiscal policies generally have reflected governments' willingness to forego revenues in an effort to aid the oil and gas industry, with certain exemptions. Since 1988, changes have reflected trends of consolidation and less government willingness to forego revenues. A federal large corporations capital tax has been introduced, the natural gas exploration holiday in Alberta expired, new oil royalties were introduced, and changes were made in fiscal regimes to accomodate horizontal drilling in Saskatchewan and Manitoba. In this document, the existing corporate tax regime is described. A comparison of fiscal regimes must recognize the differing scale and nature of oil and gas operations among the 4 provinces, with Alberta accounting for 80-90% of Canada's oil and gas productions, while British Columbia, Saskatchewan and Manitoba are much smaller producers. The document describes Crown royalties and incentives and freehold taxes for each type of fuel (crude oil, natural gas, natural gas byproducts, nonconventional oil). 8 figs

Uncertainty complicates the development optimization of oil and gas exploration and production projects, but methods have been devised to analyze uncertainty and its impact on optimal decision-making. This paper compares two methods for development optimization and uncertainty analysis: Monte Carlo (MC) simulation and stochastic programming. Two example problems for a gas field development and an oilfield development are solved and discussed to elaborate the advantages and disadvantages of each method. Development optimization involves decisions regarding the configuration of initial capital investment and subsequent operational decisions. Uncertainty analysis involves the quantification of the impact of uncertain parameters on the optimum design concept. The gas field development problem is designed to highlight the differences in the implementation of the two methods and to show that both methods yield the exact same optimum design. The results show that both MC optimization and stochastic programming provide unique benefits, and that the choice of method depends on the goal of the analysis. While the MC method generates more useful information, along with the optimum design configuration, the stochastic programming method is more computationally efficient in determining the optimal solution. Reservoirs comprise multiple compartments and layers with multiphase flow of oil, water, and gas. We present a workflow for development optimization under uncertainty for these reservoirs, and solve an example on the design optimization of a multicompartment, multilayer oilfield development.

1993-01-01

Continental Shelf Associates, Inc. (CSA) was contracted to conduct a three-year study of the environmental and health related impacts of produced water and sand discharges from oil and gas operations. Data on naturally occurring radioactive materials (NORM), heavy metals, and hydrocarbons in water, sediment, and biota will be collected and evaluated. Health related impacts will be studied through field collections and analyses of commercially- and recreationally-important fish and shellfish tissues. Additionally, information on seafood catch, consumption, and use patterns for the Gulf of Mexico will be gathered and analyzed. The facilities to be studied will include both offshore and coastal facilities in the Gulf of Mexico. Coastal sites will be additionally studied to determine ecological recovery of impacted wetland and open bay areas. The economic impact of existing and proposed effluent federal and state regulations will also be evaluated. The primary objectives of the project are to increase the base of scientific knowledge concerning (1) the fate and environmental effects of organics, trace metals, and NORM in water, sediment, and biota near several offshore oil and gas facilities; (2) the characteristics of produced water and produced sand discharges as they pertain to organics, trace metals, and NORM variably found in association with the discharges; (3) the recovery of four terminated produced water discharge sites located in wetland and high-energy open bay sites of coastal Louisiana and Texas; (4) the economic and energy supply impacts of existing and anticipated federal and state offshore and coastal discharge regulations; and (5) the catch, consumption and human use patterns of seafood species collected from coastal and offshore waters. Accomplishments for this period are described

Special geochemical studies of oils allowed to allocate a movable migration component of oils in the industrial oil deposits. In the field the migration component of oils varies in different parts of the field. The largest percentage of the light migration component (gas condensate of the oil) was detected in the central part of the Kama-Kinel troughs system. Monitoring of the composition of water, oil and gas (condensate light oil component) in the sedimentary cover and ni crystalline basement led to the conclusion of modern migration of hydrocarbons in sedimentary cover. This proves the existence of the modern processes of formation and reformation of oil and gas fields. This presentation is dedicated to the problem of definition of geochemical criteria of selection of hydrocarbons deposit reformation zone in the sample wells of Minibaevskaya area of Romashkinskoye field. While carrying out this work we examined 11 samples of oil from the Upper Devonian Pashiysky horizon. Four oil samples were collected from wells reckoned among the "anomalous" zones that were marked out according to the results of geophysical, oil field and geological research. Geochemical studies of oils were conducted in the laboratory of geochemistry of the Kazan (Volga-region) Federal University. The wells where the signs of hydrocarbons influx from the deep zones of the crust were recorded are considered to be "anomalous". A number of scientists connect this fact to the hypothesis about periodic influx of deep hydrocarbons to the oil deposits of Romashkinskoye field. Other researchers believe that the source rocks of the adjacent valleys sedimentary cover generate gases when entering the main zone of gas formation, which then migrate up the section and passing through the previously formed deposits of oil, change and "lighten" their composition. Regardless of the point of view on the source of the hydrocarbons, the study of the process of deposits refilling with light hydrocarbons is an

Radiological consequences of gas and oil extraction

Contamination of the environment by Technologically Enhanced Naturally Occurring Radioactive Material (TENORM) is a well-known side outcome of gas and oil extraction. Naturally Occurring Radioactive Material (NORM) means material containing the radionuclides of nature origin, i.e., K 40, U 238, Th 232 and their decay products. Technologically Enhanced means, that the physical, chemical, radiological properties, and concentrations of natural radionuclides in NORM have been altered such that there exists a potential for:Redistribution and contamination of environmental media (soil, water, and air); Increased environmental mobility in soils and groundwater; Incorporation of elevated levels of radioactivity in products and construction materials; Improper disposal or use of disposal methods that could result in unnecessary and relatively high exposures to individuals and populations via any environmental pathway and medium. NORM and TENORM are the major sources of human exposure in the World. Their contributions to the worldwide human exposure as evaluated by UNSCEAR. The radiological consequences of occupational and public exposures with TENORM are not clearly monitored and examined. The principal reason of such situation is that for a long time neither ecological organizations nor Regulatory Authorities did not consider the handling of material containing natural radionuclides (other than radon and thoron) as object for regulation of radiation safety. For instance, till now Green peace have not demonstrated any opinion about this problem. TENORM released in oil and gas extraction is a major source of environmental contamination of the Caspian Sea and soils, surface and ground waters in Azerbaijan. The origin of TENORM in oil fields of Apsheron peninsula is related to drilling, production, and processing operations. Other sources of contamination are oil well equipment where separation of contaminated water from oil takes place. Contamination of the environment leads

Hydraulic fracturing technologies, developed over the last 65 years, have only recently been combined with horizontal drilling to unlock oil and gas reserves previously deemed inaccessible. Although these technologies have dramatically increased domestic oil and natural gas production, they have also raised concerns for the potential contamination of local water supplies with the approximately 1,000 chemicals that are used throughout the process, including many known or suspected endocrine-disrupting chemicals. We discuss the need for an endocrine component to health assessments for drilling-dense regions in the context of hormonal and antihormonal activities for chemicals used. We discuss the literature on a) surface and groundwater contamination by oil and gas extraction operations, and b) potential human exposure, particularly in the context of the total hormonal and antihormonal activities present in surface and groundwater from natural and anthropogenic sources; we also discuss initial analytical results and critical knowledge gaps. In light of the potential for environmental release of oil and gas chemicals that can disrupt hormone receptor systems, we recommend methods for assessing complex hormonally active environmental mixtures. We describe a need for an endocrine-centric component for overall health assessments and provide information supporting the idea that using such a component will help explain reported adverse health trends as well as help develop recommendations for environmental impact assessments and monitoring programs.

Radiation Protection and the Management of Radioactive Waste in the Oil and Gas Industry

International Nuclear Information System (INIS)

2010-01-01

The oil and gas industry, a global industry operating in many Member States, makes extensive use of radiation generators and sealed and unsealed radioactive sources, some of which are potentially dangerous to human health and the environment if not properly controlled. In addition, significant quantities of naturally occurring radioactive material (NORM) originating from the reservoir rock are encountered during production, maintenance and decommissioning. The oil and gas industry operates in all climates and environments, including the most arduous conditions, and is continuously challenged to achieve high efficiency of operation while maintaining a high standard of safety and control - this includes the need to maintain control over occupational exposures to radiation, as well as to protect the public and the environment through proper management of wastes that may be radiologically and chemically hazardous. The oil and gas industry is organizationally and technically complex, and relies heavily on specialized service and supply companies to provide the necessary equipment and expertise, including expertise in radiation safety. This training manual is used by the IAEA as the basis for delivering its training course on radiation protection and the management of radioactive waste in the oil and gas industry. Enclosed with this manual is a CD-ROM that contains the presentational material used in the training course, the course syllabus and additional notes for course presenters. The course material is based principally on IAEA Safety Reports Series No. 34 Radiation Protection and the Management of Radioactive Waste in the Oil and Gas Industry, published by the IAEA in 2003. The training course is aimed at regulatory bodies; oil and gas field operators and support companies; workers and their representatives; health, safety and environmental professionals; and health and safety training officers. A pilot training course was held in the Syrian Arab Republic in 2000 as

The six key ways in which the oil and gas industry affects Canada, namely employment, balance of trade, products, government revenues, international technology trade and community support are stressed within the context of describing present and future oil and gas resources, Canada's petroleum and natural gas trade balance, and capital spending and product sales. Attention is also drawn to the role of the Canadian petroleum and natural gas industry as a producer and exporter of world class technology, especially in the areas of high tech exploration methods, cold-climate and offshore operations, enhanced recovery techniques, heavy oil production and and processing, mining and upgrading of oil sands bitumen, oil well firefighting, and environmental protection technology. maps, figs

The life cycle greenhouse gas emissions implications of power and hydrogen production for oil sands operations

'Full text:' The Alberta Oil Sands represent a major economic opportunity for Canada, but the industry is also a significant source of greenhouse gas (GHG) emissions. One of the sources of these emissions is the use of natural gas for the production of electricity, steam and hydrogen. Due to concerns around resource availability and price volatility, there has been considerable discussion regarding the potential replacement of natural gas with an alternative fuel. While some of the options are non-fossil and could potentially reduce GHG emissions (e.g., nuclear, geothermal, biomass), others have the potential to increase emissions. A comparative life cycle assessment was completed to investigate the relative GHG emissions, energy consumption and financial implications of replacing natural gas with coal, coke, asphaltenes or bitumen for the supply of electricity, steam and hydrogen to oil sands operations. The potential use of carbon capture and storage (CCS) was also investigated as a means of reducing GHG emissions. Preliminary results indicate that, without CCS, the natural gas systems currently in use have lower life cycle GHG emissions than gasification systems using any of the alternative fuels analysed. However, when CCS is implemented in both the coke gasification and natural gas systems, the coke systems have lower GHG emissions and financial costs than the natural gas systems (assuming a 30-year project life and a natural gas price of 6.5 USD/gigajoule). The use of CCS does impose a financial penalty though, indicating that it is unlikely to be implemented without some financial incentive. While this study has limitations and uncertainties, the preliminary results indicate that although the GHG emissions of oil sands development pose a challenge to Canada, there are opportunities available for their abatement.

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

An outlook of the Canadian Petroleum Industry, financial and operating statistics of the top 100 Canadian public oil and gas companies and 15 energy income trusts, were summarized for the fiscal year ending in 1996. In general, 1996 was a good year for the industry. Greater industry financing resulted in increased drilling activity and good stock market returns for investors. However, strong commodity prices also resulted in record levels of hedging activity, which meant lost revenues for the industry. The top 100 companies recorded losses of about $800 million in 1996, largely on crude oil hedges. The fact that volumes hedged forward to 1997 are down from 1996 indicate that many companies are rethinking their commitment to risk management. Details of crude oil and natural gas prices and production levels during 1996 were provided. A list of significant corporate mergers and acquisitions during the year under review rounded out the presentation

Market for oil and gas assets defined in survey

This paper reports that hundreds of companies are currently active in the oil and gas acquisition and disposition marketplace, but unfortunately, the entire sale process within the industry continues to operate inefficiently. The mechanism for selling oil and gas properties in this secondary market - as used here, a term that excludes initial investments in oil and gas assets and sales of drilling program shares - is sort of catch-as-catch- can. Identifying who is seeking what type of property at any time is difficult, bordering on guesswork. A recent survey of 186 company representatives and individuals, who declared themselves as in the market, disclosed some of this information at a point in time

Interest grows in African oil and gas opportunities

As African countries continue a slow drift towards democratic government and market economics, the continent is increasingly attractive to international oil and gas companies. Though Africa remains politically diverse, and its volatile politics remains a major barrier to petroleum companies, a number of recent developments reflect its growing significance for the industry. Among recent projects and events reflecting changes in Africa: oil and gas exporter Algeria has invited foreign oil companies to help develop major gas discoveries, with a view to boosting exports to Europe; oil and gas producer Egypt invited foreign companies to explore in the Nile Delta region, and the result appears to be a flowering world scale gas play; west African offshore exploration has entered deep water and new areas, and a number of major projects are expected in years to come; Nigeria`s reputation as a difficult place to operate has been justified by recent political and civil events, but a long-planned liquefied natural gas (LNG) export plant is being built there; South Africa, which has returned to the international scene after years of trade isolation because of apartheid, is emerging as a potential driver for energy industry schemes throughout the continent. Activities are discussed.

Shaffer, Franklin; de Vera, Giorgio; Lee, Kenneth; Savas, Ömer

2013-11-01

Drilling for oil or gas in the Gulf of Mexico is increasing rapidly at depths up to three miles. The National Commission on the Deepwater Horizon Oil Leak concluded that inaccurate estimates of the leak rate from the Deepwater Horizon caused an inadequate response and attempts to cap the leak to fail. The first response to a submerged oil/gas leak will be to send a Remotely Operated Vehicle (ROV) down to view the leak. During the response to the Deepwater Horizon crisis, the authors Savas and Shaffer were members of the Flow Rate Technical Group's Plume Team who used ROV video to develop the FRTG's first official estimates of the oil leak rate. Savas and Shaffer developed an approach using the larger, faster jet features (e.g., turbulent eddies, vortices, entrained particles) in the near-field developing zone to measure discharge rates. The authors have since used the Berkeley Tow Tank to test this approach on submerged dye-colored water jets and compressed air jets. Image Correlation Velocimetry has been applied to measure the velocity of visible features. Results from tests in the Berkeley Tow Tank and submerged oil jets in the OHMSETT facility will be presented.

The purpose of this report is to describe the physical operations which take place within the petroleum and natural gas industries of the US. This information was the basis for the overall network design and the detailed data requirements for the Emergency Management Information System (EEMIS) of the US Department of Energy (DOE). Since EEMIS represents the entire oil and gas systems this report can be used to obtain a basic understanding of the entire energy system, from production to consumption, that is composed of the US oil and gas industries.

Oil and Gas Emergency Policy: Germany 2012 update

Germany has very little domestic oil and natural gas production and relies heavily on imports. It has well diversified and flexible oil and natural gas supply infrastructure, which consists of crude, product and gas pipelines and crude and oil product import terminals. Natural gas is imported into Germany exclusively by cross-border pipeline. The country has no LNG infrastructure, although some German companies have booked capacities in overseas LNG terminals. Oil continues to be the main source of energy in Germany although it has declined markedly since the early 1970s. It now represents approximately 32% of Germany’s total primary energy supply (TPES). Natural gas consumption in Germany has declined 10% since 2006. Demand was 90 bcm in 2010, down from 100 bcm in 2005. According to government commissioned analysis, the total consumption of natural gas in Germany is expected to continue to decline over the long term. The share of natural gas in Germany’s TPES is currently around 22%. German oil stock levels are generally well above the required 90-days. Total oil stock levels in Germany were equivalent to 140 days net imports in April 2012. Since 1998, the German oil stockholding agency (EBV) has been solely responsible for meeting Germany's 90-day stockholding obligation. The Oil Stockholding Act stipulates that the EBV shall constantly maintain stocks of oil and petroleum products at a level equivalent to or above 90 days of net imports. There is no minimum stockholding obligation on industry, so industry held commercial stocks are held in addition to the EBV stocks. There are several legal tools available to German authorities for natural gas emergency response. These include Ordinances that can be used to restrict the sale, purchase or use of goods, both in terms of quantity and time, or permit them only for certain priority purposes, to ensure that vital energy needs are met. There are no compulsory natural gas storage requirements in Germany, and no

Radioisotope techniques for process optimisation and control in the offshore oil and gas industries

International Nuclear Information System (INIS)

Charlton, J.S.

2002-01-01

For over fifty years, radioisotope technology has been used by the oil industry to solve problems and to help optimise process operations. The widespread development of offshore oil and gas fields has brought, and continues to bring, new challenges and, in response, new or modified applications of radioisotope technology have been introduced. This paper presents case studies, which illustrate the use of radioisotopes, both in the sub-sea environment and on the offshore production platforms. On the platform, radioisotope techniques applied singly or in combination, have been applied to the performance assessment of oil/gas separation and gas dehydration units. Novel nucleonic instrumentation has been developed for the control of three-phase separators. Sub-sea, radioactive tracers and/or sealed sources have been used to investigate the integrity of submerged structures and to troubleshoot pipeline problems. The continuing expansion in the use of this technology stems from industry increasing awareness of its versatility and from the fact that the benefits it confers can be obtained at a relatively modest cost. Examples of economic benefit described in the paper are associated with production enhancements derived from the ability of radioisotope technology to measure performance and diagnose problems on line, without disrupting process operations in any way.

Toxicology of oil field pollutants in cattle: a review.

Science.gov (United States)

Coppock, R W; Mostrom, M S; Khan, A A; Semalulu, S S

1995-12-01

Cattle are poisoned by petroleum and substances used in drilling and operating oil and gas wells. The most common reported route of exposure for non-gaseous material is oral. Exposures occur when the petroleum or chemicals used in oil and gas field activities are available to cattle and when water and feed-stuffs are contaminated. Cattle, as a leisure activity, explore and ingest crude oil. Based on morbidity patterns in cattle herds, the amount of toxic substance ingested is variable. When water and feedstuffs are contaminated, a larger number in a herd generally are affected. Cattle have been poisoned by a wide variety of chemical mixtures. For substances high in volatile hydrocarbons, the lung is a target organ. Hydrocarbons also target the kidney, liver and brain. Exposure-linked abortions have been reported in cattle. Diethylene glycol targets the brain, liver and kidney. The reported threshold dose of unweathered oil for cattle ranges from 2.5 to 5.0 ml/kg bw, and the reported threshold dose for weathered oil is 8.0 ml/kg.

Oil and Gas Emergency Policy: Japan 2013 update

Oil remains the most significant energy source in Japan, accounting for some 45% of the country’s total primary energy supply (TPES) in 2011. Japan’s oil demand steadily decreased from 5.71 mb/d in 1997 to 4.47 mb/d in 2010. However, its oil demand increased to 4.48 mb/d in 2011 and 4.73 mb/d in 2012 due to the Great East Japan Earthquake in March 2011 and its subsequent impacts. The transport sector represented around 38% of total consumption in 2010, while the industry sector accounted for 30%. A significant proportion of the industry sector’s oil demand comes from the chemical industry. Of the 4.8 mb/d of oil imported by Japan in 2012, 3.5 mb/d consisted of crude oil, 209 kb/d of NGLs and feedstocks, and some 1.2 mb/d of refined products. About 83% of Japan’s crude oil imports in 2012 came from the Middle East. The country has 27 operational refineries with a total crude distillation capacity of around 4.5 mb/d. Japan meets its 90-day stockholding obligation to the IEA by holding government emergency stocks and by placing a minimum stockholding obligation on industry. JOGMEC’s primary role is to manage public stocks under the Oil Stockpiling Act, while industry (refineries, specified distributors and importers) is obliged to hold the equivalent of 70 days of their daily imports, sales or refinery production, based on the average of the previous 12 months. The public stocks mostly consist of crude oil, but the Administration has expanded its emergency inventory to include four categories of refined products - gasoline, kerosene, fuel oil and diesel oil. Japan held some 591 million barrels (mb) of oil stocks at the end of January 2013, equating to 166 days of 2011 net-imports (92 days of government stocks and 74 days of industry stocks). Around 72% of total stocks were held in the form of crude oil. Japan has consistently met its minimum IEA stockholding obligation. The share of natural gas in the country’s TPES increased significantly from 17% in 2010

Operational Excellence in Manufacturing, Service and the Oil & Gas: the Sectorial Definitional Constructs and Risk Management Implication

Full Text Available The current global business climate has not been favorable to most firms irrespective of industry affiliation. That condition necessitated companies to adopt operational excellence as a strategy for optimising output with little resources, reducing lead time with the efficient use of assets and employees and avoiding safety and health issues to people and the environment. As a result of the need for operational excellence, many kinds of literature defined the concept based on the context of industry or sector. Industries such as manufacturing, services, oil and gas, mining and so many industries to mention a few, have their unique construct in the definition and therefore causing dilemma on which dimension to hold on to. It is against this backdrop that this paper synthesizes and integrate all the varying dimensions and fuses out similarities, differences and the antecedence of research directions taken on the few mentioned sectors. The paper thus concludes that the unique construct among all the definitions is continuous improvement, cost reduction, quality, time utilization, operational efficiency, staff involvement and output optimisation. However, they varied on risk management, staff health, safety and the concern for the environment, which is unique to oil and gas industry and that can affect the choice of research variables.

The Viability of the Oil and Gas Industry within the Former Soviet Union, excluding Kazakhstan

Energy Technology Data Exchange (ETDEWEB)

Coish, J.; Pyne, M.

2004-01-15

The former Soviet Union (FSU) has huge potential in the future of the world's oil and gas industry. The FSU includes some of the biggest producers and consumers of oil and gas in the world, and many of these countries include areas that lie untouched or explored. FSU territory also surrounds the Caspian Sea, which is itself a hotbed of activity in the oil and gas industry. The Caspian alone is important to world energy markets because of its own potential for oil and gas production and export, and this adds to the overall potential of the FSU. The FSU has been moving towards a free market economy since the fall of communism in the early 90's, and as such, is becoming a much more attractive area for foreign companies to operate. The FSU countries still requires foreign investment for their respective industries, and some of them have even put into place legislation to provide benefits to foreign investors. There are many types of foreign investment required in the FSU. Much of the infrastructure already in place is old and dilapidated, and requires maintenance and improvement. As well, new equipment and technologies for exploration and production are required to tap the oil and gas resources that lie in inconvenient locations. Finally, transportation of the oil and gas is a major issue here, as many of the fields are in hard to reach areas, and thus pipeline projects are increasing. Since the fall of communism, the FSU has been opening its doors more and more to foreign investors eager to bite into the huge market, and many of the largest oil and gas companies in the world are already operating there. The industries are still young to foreign investment, however, and those companies who get their foot in the door early, will be able to reap the benefits for years to come.

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.

Introduction and objective. The Karachaganak oil and gas condensate field (KOGCF), one of the largest in the world, located in the Republic of Kazakhstan (RoK) in Central Asia, is surrounded by 10 settlements with a total population of 9,000 people. Approximately73% of this population constantly mention a specific odour of rotten eggs in the air, typical for hydrogen sulfide (H2S) emissions, and the occurrence of low-level concentrations of hydrogen sulfide around certain industrial installations (esp. oil refineries) is a well known fact. Therefore, this study aimed at determining the impact on human health and the economic damage to the country due to H2S emissions. Materials and method. Dose-response dependency between H2S concentrations in the air and cardiovascular morbidity using multiple regression analysis was applied. Economic damage from morbidity was derived with a newly-developed method, with Kazakhstani peculiarities taken into account. Results.Hydrogen sulfide air pollution due to the KOGCF activity costs the state almost $60,000 per year. Moreover, this is the reason for a more than 40% rise incardiovascular morbidity in the region. Conclusion. The reduction of hydrogen sulfide emissions into the air is recommended, as well as successive constant ambient air monitoring in future. Economic damage evaluation should be made mandatory, on a legal basis, whenever an industrial facility operation results in associated air pollution.

The microseepage of natural gas from subsurface hydrocarbon reservoirs is a widespread process in petroleum basins. On a global scale, microseepage represents an important natural source of atmospheric methane (CH4). To date, microseepage CH4 flux data have been obtained from 20 petroleum systems in North America, Europe, and Asia. While the seasonal variations of gas flux due to soil methanotrophic activity are known, the role of geological factors in controlling gas fluxes has been poorly investigated. Here we present new microseepage data from the Dawanqi oil-gas field located within the Tarim Basin (China), a petroleum system characterized by intense faulting and shallow (petroleum fields with active tectonics. Our results confirm that dry soil over petroleum fields can be a net source of atmospheric CH4 and its flux is primarily controlled by faulting, and reservoir depth and pressure. These factors shall be considered in global bottom-up seepage emission estimates.

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

International Nuclear Information System (INIS)

Pasternak, Michael

2013-01-01

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

Comparison of vibration and noise level on the boiler during operation of fuel heavy oil (mazut) and on natural gas in TO 'Istok' - Toplifikacija - Joint-Stock Co. for district heating Skopje (Macedonia)

1999-01-01

In the beginning of the heat season 1997/98, we started to use natural gas as a second fuel (the basic fuel is heavy fuel oil). Preparations were made for the use of natural gas in half of the TO 'Istok' Plant capacity (147 MW) in Skopje (Macedonia). During operation on natural gas, we noted that the levels of vibration and noise are higher when operating on heavy fuel oil. This was the reason why an investigation was carried out through a special company working on that issue. The investigation was made by measurement of vibration levels and noise at the boiler furnace in various orientation and levels. This material gives the results and conclusions from that investigation. A comparison has been made of the dynamic conditions and noise levels of the same boilers during operation on heavy fuel oil and on natural gas. We also compared the dynamic conditions and noise levels of different boilers during operations on natural gas, with different equipment for the atomizing of the natural gas. Conclusions on the dynamic conditions of the investigated boilers while operating on heavy fuel oil and on natural gas are given at the end of this material. (Author)

Geographic information system (GIS)-based maps of Appalachian basin oil and gas fields: Chapter C.2 in Coal and petroleum resources in the Appalachian basin: distribution, geologic framework, and geochemical character

One of the more recent maps of Appalachian basin oil and gas fields (and the adjoining Black Warrior basin) is the U.S. Geological Survey (USGS) compilation by Mast and others (1998) (see Trippi and others, this volume, chap. I.1). This map is part of a larger oil and gas field map for the conterminous United States that was derived by Mast and others (1998) from the Well History Control System (WHCS) database of Petroleum Information, Inc. (now IHS Energy Group). Rather than constructing the map from the approximately 500,000 proprietary wells in the Appalachian and Black Warrior part of the WHCS database, Mast and others (1998) subdivided the region into a grid of 1-mi2 (square mile) cells and allocated an appropriate type of hydrocarbon production (oil production, gas production, oil and gas production, or explored but no production) to each cell. Each 1-mi2 cell contains from 0 to 5 or more exploratory and (or) development wells. For example, if the wells in the 1-mi2 cell consisted of three oil wells, one gas well, and one dry well, then the cell would be characterized on the map as an area of oil and gas production. The map by Mast and others (1998) accurately shows the distribution and types of hydrocarbon accumulation in the Appalachian and Black Warrior basins, but it does not show the names of individual fields. To determine the locality and name of individual oil and gas fields, one must refer to State oil and gas maps (for example, Harper and others, 1982), which are generally published at scales of 1:250,000 or 1:500,000 (see References Cited), and (or) published journal articles.

Thermodynamic analysis of oil and gas platforms over various production profiles and feed compositions

DEFF Research Database (Denmark)

Nguyen, Tuong-Van; Junior, Silvio de Oliveira

2017-01-01

Oil and gas platforms present similar structural designs but process fluids with different thermo-physical and chemical properties. In addition, the field properties, such as the gas-to-oil and water-to-oil ratios, change significantly over time. It is therefore not possible to suggest a standard...... of energy and exergy. Feed compositions and production profiles, which correspond to data from actual fields, are used for calibrating the simulations. In a second step, the minimum energy and exergy losses of the platform are assessed by performing thermodynamic analyses, assuming an ideal scenario...... in which all processes are run at their design points. This approach proves to be useful for evaluating consistently different options for oil and gas production, and for determining, in a further step, the most promising solutions for minimising the energy use over a field lifetime....

US crude oil, natural gas, and natural gas liquids reserves

Oil and gas conservation in Saskatchewan

International Nuclear Information System (INIS)

Sereda, M.A.

1997-01-01

The Saskatchewan's Oil and Gas Conservation Act provides legislative authority for the Oil and Gas Conservation Regulations, 1985. The main purposes of the Act are to maximize oil and gas recovery, to allow each owner the opportunity of obtaining his share of oil or gas and to protect the environment and prevent waste. The document under review described how this legislative intent is fulfilled through the spacing of wells, the setting of allowables, and approval of waterflood and enhanced recovery projects, while considering equitable drainage of oil and gas. Specific topics dealt with include: vertical well spacing, infill drilling, off-target drilling, horizontal well spacing, and allowables. The concepts of voluntary and statutory pooling as well as voluntary and statutory unitization were explained. Examples of waterflood and enhanced oil recovery projects were provided. The regulation relating to oil and gas conservation were first implemented in 1952 and evolved to their present form through a series of changes and amendments. The most significant changes to the regulations were made in 1991 when horizontal drilling needed to be accommodated. 1 tab

Have oil and gas prices got separated?

International Nuclear Information System (INIS)

Erdős, Péter

2012-01-01

This paper applies vector error correction models that show that oil and natural gas prices decoupled around 2009. Before 2009, US and UK gas prices had a long-term equilibrium with crude prices to which gas prices always reverted after exogenous shocks. Both US and UK gas prices adjusted to the crude oil price individually, and departure from the equilibrium gas price on one continent resulted in a similar departure on the other. After an exogenous shock, the adjustment between US and UK gas prices took approximately 20 weeks on average, and the convergence was mediated mainly by crude oil with a necessary condition that arbitrage across the Atlantic was possible. After 2009, however, the UK gas price has remained integrated with oil price, but the US gas price decoupled from crude oil price and the European gas price, as the Atlantic arbitrage has halted. The oversupply from shale gas production has not been mitigated by North American export, as there has been no liquefying and export capacity. - Highlights: ► VEC models are applied to investigate the relationship between oil and natural gas prices. ► While natural gas prices in Europe and Asia react to oil price, US gas price decoupled from oil in 2009. ► Since 2009, the US gas price has decoupled from the European and Asian gas prices.

Combilift ideal for maneuvering oil and gas equipment

Energy Technology Data Exchange (ETDEWEB)

Anon.

2009-07-15

This article described an innovative forklift that responds to the oil industry's need for a safer, better and easier way to move long tubular products that cannot be carried high in the air. The Gator Jaw is a duplex pipe clamp attachment that secures to the Combilift forklift carriage. The clamp arm can be hydraulically moved upwards to allow the operator full use of the forks without interference from the hold down arm. The Combilift's platform is ideal for maneuvering oil and gas equipment close to the ground. Since it can travel sideways, the length of the load is not critical. The Gator Jaw's unique design makes it possible for one forklift to handle both skids and pallets. The C-Series product extends to the subsea oil and gas industry, which works with long loads such as oil drilling tools and pipe. The benefits include safer product handling, significant space savings, increased productivity and versatile indoor and outdoor use. The machines are available with a fuel-efficient liquefied petroleum gas (LPG) or diesel engine. 1 fig.

The transformation of the oil and gas sector with the separation of independent enterprises and organizations providing services in the oil and gas service sector is compared by the author with the trend of rapid development of the service sector in the postindustrial economy. The purpose of the study is to identify the general and specific characteristics of modern oil and gas services and to determine the directions for the transformation of organizational forms of entrepreneurship in the sphere under consideration. The growth of quantitative parameters of the oil and gas services market has been analyzed. The classification of this market is proposed depending on the place of services in a single technological cycle in relation to the main oil production process. The positive consequences of the development of oil and gas services for the development of oil and gas production have been systematized. Basic organizational models of entrepreneurship development in oil and gas service are generalized and substantiated. It is shown that the main influence in the market of services is taken by vertically integrated national oil and gas companies, as well as by international companies that provide service support for the work of Russian oil and gas companies. The results of a comparative analysis of advantages and disadvantages of organizational models of entrepreneurship in the field of oil and gas services are presented. It is proved that oil and gas service as an organizational form of entrepreneurship in its development reflects the general trends of the post-industrial economy. Specific features of oil and gas service in Russia are singled out. The revealed directions of transformation of organizational forms of entrepreneurship in the sphere of oil and gas service in current conditions can be used in the formation of state programs in the field of industrial

Oil/gas collector/separator for underwater oil leaks

Energy Technology Data Exchange (ETDEWEB)

Henning, C.D.

1992-12-31

This invention is comprised of an oil/gas collector/separator for recovery of oil leaking, for example, from an offshore or underwater oil well. The separator is floated over the point of the leak and tethered in place so as to receive oil/gas floating, or forced under pressure, toward the water surface from either a broken or leaking oil well casing, line, or sunken ship. The separator is provided with a downwardly extending skirt to contain the oil/gas which floats or is forced upward into a dome wherein the gas is separated from the oil/water, with the gas being flared (burned) at the top of the dome, and the oil is separated from water and pumped to a point of use. Since the density of oil is less than that of water it can be easily separated from any water entering the dome.

, while households and other small consumers, numbering over 33 thousand, account for 2% of the total. The Swedish Energy Agency (SEA), under the Ministry of Enterprise, Energy and Communications, has the main responsibility for both oil and natural gas emergency response policy. Sweden fulfils its oil stockholding requirements to both the IEA and the European Union by placing minimum stockholding obligations on industry and major consumers. During a supply disruption and as a contribution to an IEA collective action, Swedish authorities would reduce the minimum obligation, thereby granting operators permission to draw stocks below the minimum level. In a natural gas crisis, supplies to protected customers (i.e. households) are safeguarded while the physical balance of the gas system would be maintained by restricting or discontinuing supplies to non-protected customers in a crisis. System operators are obliged to have in place crisis plans for dealing with emergency situations, including a strategy for reducing supplies to customers.

Enhanced oil recovery (EOR) and hydraulic fracturing practices are commonly used methods to improve hydrocarbon extraction efficiency; however the environmental impacts of such practices remain poorly understood. EOR is particularly prevalent in oil fields throughout California where water resources are in high demand and disposal of high volumes of produced water may affect groundwater quality. Consequently, it is essential to better understand the fate of injected (EOR) fluids in California and other subsurface petroleum systems, as well as any potential effect on nearby aquifer systems. Noble gases can be used as tracers to understand hydrocarbon generation, migration, and storage conditions, as well as the relative proportions of oil and water present in the subsurface. In addition, a noble gas signature diagnostic of injected (EOR) fluids can be readily identified. We report noble gas isotope and concentration data in casing gases from oil production wells in the Lost Hills oil field, northwest of Bakersfield, California, and injectate gas data from the Fruitvale oil field, located within the city of Bakersfield. Casing and injectate gas data are used to: 1) establish pristine hydrocarbon noble-gas signatures and the processes controlling noble gas distributions, 2) characterize the noble gas signature of injectate fluids, 3) trace injectate fluids in the subsurface, and 4) construct a model to estimate EOR efficiency. Noble gas results range from pristine to significantly modified by EOR, and can be best explained using a solubility exchange model between oil and connate/formation fluids, followed by gas exsolution upon production. This model is sensitive to oil-water interaction during hydrocarbon expulsion, migration, and storage at reservoir conditions, as well as any subsequent modification by EOR.

Oil and gas in the environment

Our society and economy have become dependent on oil and gas. The UK uses oil and gas for more than two-thirds of its energy needs - to run its transport network, heat its homes, in industrial processes, and to produce over a quarter of its electricity. There has been a steady increase in consumption of petrol, diesel and aviation fuel since 1970, mostly for transportation, although consumption of fuel oil has fallen dramatically. This has largely been replaced in the industrial and domestic sectors by gas, the consumption of which has risen sharply since 1990. This report assesses how this dependence on oil and gas is affecting the environment, and looks at the impact of the increasing consumption of oil and gas on the environment. The need to regulate and manage these impacts has been recognised for many years. The report forms the Environment Agency's view on the general state of pollution of the environment in relation to oil and gas. It looks at how well existing regulations and controls are working in practice and what more needs to be done, both by the Agency itself and by others, to reduce pollution. After giving a background to the formation of oil and gas and the history of their exploitation, the report summarises who does what in regulation. It then takes a life-cycle approach to look at the pressures on the environment from the exploration, production, transportation, refining, storage, and the use of oil and gas, and finally the disposal of used oil and oily waste.

Environmental law issues: Offshore oil and gas activities and tanker transportation

International Nuclear Information System (INIS)

Chapman, P.M.

1991-01-01

The environmental law issues that arise from offshore oil/gas activities and petroleum transport are reviewed, focusing on marine oil pollution and especially on the issues surrounding accidental spills. Some observations are offered on the context of these issues, namely on the risks of oil spills, the difficulty of spill response in the ocean and on shorelines, and the possible environmental damage. Environmental control of petroleum operations is discussed with reference to Canadian regulation, the primary source of which is the Oil and Gas Production and Conservation Act. These regulations require developmental approval for offshore operations, formulation of plans for foreseeable spill emergencies, and compensation to those affected by spills, notably those in the fishing industry. Ship-source oil pollution and spill compensation is discussed with reference to international agreements and the Canada Shipping Act. Some problems and trends with oil spill compensation and recovery for environmental damage are noted in such areas as tanker ship standards, cleanup capabilities, and inadequacy of spill penalties and compensation. 18 refs., 1 fig

Fortum intends to be an active player in the structural reorganization of the oil business by utilizing its niche position in oil refining. Fortum produces sophisticated motor fuel components, which it uses in its reformulated gasolines and sells and exports to other oil companies, even to highly demanding markets in California. The increase in the price of crude oil considerably improved the results of Oil and Gas Upstream. Similarly, an improvement in the refining margin, as well as profitable shipping operations and a strong demand for gasoline components, boosted the results of Oil Refining and Marketing. (orig.)

The Farmers' Advocate Office was created in 1972 to help put Alberta mineral owners on an equal footing with the energy sector. Most mineral owners are at a disadvantage when dealing with the disposition of their minerals because they have little or no knowledge of what they own or what their surface rights are. This paper addresses key features of mineral leasing arrangements in Alberta and explains their potential impact. It also brings to the mineral owner's attention some specific problems and concerns including mineral rights, the lease agreement, signing considerations, length of leases, delayed production payment, drilling rental, royalties, and gas cost allowance. Issues regarding oil and gas production including shut-in wells, off-set clauses , drilling depth, taxes and prepayment for minerals are also discussed from the perspective of a mineral owner

In considering the potential of the United Kingdom for investment in the oil and gas industry, four factors are discussed. They are: the importance of certainty in identifying markets; the importance of infrastructure in assisting follow-on developments in mature oil and gas fields; the UK's competitive position in the world investment market; fiscal terms in the UK as compared with those offered by other countries. The conclusion drawn is that the UK needs to be responsive to its status as a mature oil and gas area and have the flexibility to stimulate investment in frontier areas. Stability in both the fiscal regime and also handling issues like market access is important. There is a need to capitalise on the many advantages conferred by the existing infrastructure in mature areas. (UK)

Simulation study to determine the feasibility of injecting hydrogen sulfide, carbon dioxide and nitrogen gas injection to improve gas and oil recovery oil-rim reservoir

Eid, Mohamed El Gohary

This study is combining two important and complicated processes; Enhanced Oil Recovery, EOR, from the oil rim and Enhanced Gas Recovery, EGR from the gas cap using nonhydrocarbon injection gases. EOR is proven technology that is continuously evolving to meet increased demand and oil production and desire to augment oil reserves. On the other hand, the rapid growth of the industrial and urban development has generated an unprecedented power demand, particularly during summer months. The required gas supplies to meet this demand are being stretched. To free up gas supply, alternative injectants to hydrocarbon gas are being reviewed to support reservoir pressure and maximize oil and gas recovery in oil rim reservoirs. In this study, a multi layered heterogeneous gas reservoir with an oil rim was selected to identify the most optimized development plan for maximum oil and gas recovery. The integrated reservoir characterization model and the pertinent transformed reservoir simulation history matched model were quality assured and quality checked. The development scheme is identified, in which the pattern and completion of the wells are optimized to best adapt to the heterogeneity of the reservoir. Lateral and maximum block contact holes will be investigated. The non-hydrocarbon gases considered for this study are hydrogen sulphide, carbon dioxide and nitrogen, utilized to investigate miscible and immiscible EOR processes. In November 2010, re-vaporization study, was completed successfully, the first in the UAE, with an ultimate objective is to examine the gas and condensate production in gas reservoir using non hydrocarbon gases. Field development options and proces schemes as well as reservoir management and long term business plans including phases of implementation will be identified and assured. The development option that maximizes the ultimate recovery factor will be evaluated and selected. The study achieved satisfactory results in integrating gas and oil
