Full Text Available Strict ecological legislation, especially in highly developed countries, imposed requirements for the purification of industrial effluents and the need for efficient oil clean up after sea and inland water spills. Although numerous processes have been developed, the application of sorbents is still one of the most efficient methods to remove heavy metal ions, dyes and crude oil from water. Recently, special attention was paid to sorbents based on natural fibres. A review of studies concerning the sorption properties of wool is presented in this paper. The presence of various functional groups on the wool fibre surface contributes to the efficient sorption of heavy metal ions and dyes. A hydrophobic, scaly surface and fibre crimp strongly influence the high sorption capacity of wool for oil. Wool has great sorption potential even as a recycled material. Accordingly, it can be used as a viable substitute to commercially available synthetic sorbents that show poor biodegradab ility.

Sorption of 226Ra from oil effluents onto synthetic cation exchangers

International Nuclear Information System (INIS)

Attar, L.; Safia, M.

2014-01-01

Increasing environmental awareness is being urged for the safe disposal of 226 Ra-contaminated production water generated in the oil industry. Brainiest, antimony silicate and their cationic derivatives were studied for the take-up of 226 Ra using the batch-type method under experimentally determined parameters, viz. contact time, solution-solid ratio and 226 Ra concentration. Data was expressed in terms of distribution coefficients. Sorption experiments were performed in different concentrations of nitric acid in order to speculate the mechanism of 226 Ra uptake. Variation in the magnitude of sorption efficiency of the materials in the presence of the major components of waste streams, i.e. Na + , K + and Ca 2+ , revealed that K + was the greatest competitor and Na + the least. The application of the materials to sorb 226 Ra from actual oil co-production water samples, collected from Der Ezzor and Al Fourat petroleum companies (DEZPC and AFPC), was interpreted in terms of the exchange properties of the materials and water characterisation. Of the parameters studied, the selectivity of materials was shown to be greatly dependent on the pH of wastewater to be treated. (author)

Spills of Hydraulic Fracturing Chemicals on Agricultural Topsoil: Biodegradation, Sorption, and Co-contaminant Interactions.

Hydraulic fracturing frequently occurs on agricultural land. Yet the extent of sorption, transformation, and interactions among the numerous organic frac fluid and oil and gas wastewater constituents upon environmental release is hardly known. Thus, this study aims to advance our current understanding of processes that control the environmental fate and toxicity of commonly used hydraulic fracturing chemicals. Poly(ethylene glycol) surfactants were completely biodegraded in agricultural topsoil within 42-71 days, but their transformation was impeded in the presence of the biocide glutaraldehyde and was completely inhibited by salt at concentrations typical for oil and gas wastewater. At the same time, aqueous glutaraldehyde concentrations decreased due to sorption to soil and were completely biodegraded within 33-57 days. While no aqueous removal of polyacrylamide friction reducer was observed over a period of 6 months, it cross-linked with glutaraldehyde, further lowering the biocide's aqueous concentration. These findings highlight the necessity to consider co-contaminant effects when we evaluate the risk of frac fluid additives and oil and gas wastewater constituents in agricultural soils in order to fully understand their human health impacts, likelihood for crop uptake, and potential for groundwater contamination.

Gas sorption properties of zwitterion-functionalized carbon nanotubes

Energy Technology Data Exchange (ETDEWEB)

Surapathi, Anil; Chen, Hang-yan; Marand, Eva; Karl Johnson, J.; Sedlakova, Zdenka

2013-02-01

We have functionalized carbon nanotubes with carboxylic acid and zwitterion groups. We have evaluated the effect of functionalization by measuring the sorption of CO{sub 2}, CH{sub 4}, and N{sub 2} at 35°C for pressures up to 10 bar. Zwitterion functionalized nanotubes were found to be highly hygroscopic. Thermal gravimetric analysis indicates that water can be desorbed at about 200°C. The adsorption of gases in zwitterion functionalized nanotubes is dramatically reduced compared with nanotubes functionalized with carboxylic acid groups. The presence of water on the zwitterion functionalized nanotube reduces the sorption even further. Molecular simulations show that three or more zwitterion groups per tube entrance are required to significantly reduce the flux of CO{sub 2} into the tubes. Simulations also show that gas phase water is rapidly sorbed into the zwitterion functionalized nanotubes, both increasing the free energy barrier to CO{sub 2} entering the tube and also lowering the equilibrium adsorption through competitive adsorption.

Comparison of carbon-dioxide and propane sorption at ambient temperature was used for characterising the difference of the structure of hazardous and non hazardous coals. However, hazardous coals were found more microporous or contain more closed pores than non hazardous ones, this difference couldn`t have been enlarged and attributed to one petrographic component by producing the density fractions. Gas sorption isobars (nitrogen, methane, ethane) are proposed to make a distinction between fine pore structure of coals. (orig.)

Utilization of CO2 to stimulate natural gas production in previously fractured shale-dominated reservoirs where CO2 remains in place for long-term storage may be an attractive new strategy for reducing the cost of managing anthropogenic CO2. A preliminary analysis of capacities and potential revenues in US shale plays suggests nearly 390 tcf in additional gas recovery may be possible via CO2 driven enhanced gas recovery. However, reservoir transmissivity properties, optimum gas recovery rates, and ultimate fate of CO2 vary among reservoirs, potentially increasing operational costs and environmental risks. In this paper, we identify key mechanisms controlling the sorption of CH4 and CO2 onto phyllosilicates and processes occurring in mixed gas systems that have the potential of impacting fluid transfer and CO2 storage in shale dominated formations. Through a unique set of in situ experimental techniques coupled with molecular-level simulations, we identify structural transformations occurring to clay minerals, optimal CO2/CH4 gas exchange conditions, and distinguish between adsorbed and intercalated gases in a mixed gas system. For example, based on in situ measurements with magic angle spinning NMR, intercalation of CO2 within the montmorillonite structure occurs in CH4/CO2 gas mixtures containing low concentrations (hydrocarbon recovery processes.

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

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.

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.

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

Oil shale is an abundant, undeveloped natural resource which has natural sorbent properties, and its ash has natural cementitious properties. Oil shale may be blended with coal, biomass, municipal wastes, waste tires, or other waste feedstock materials to provide the joint benefit of adding energy content while adsorbing and removing sulfur, halides, and volatile metal pollutants, and while also reducing nitrogen oxide pollutants. Oil shale depolymerization-pyrolysis-devolatilization and sorption scoping studies indicate oil shale particle sorption rates and sorption capacity can be comparable to limestone sorbents for capture of SO2 and SO3. Additionally, kerogen released from the shale was shown to have the potential to reduce NOx emissions through the well established “reburning” chemistry similar to natural gas, fuel oil, and micronized coal. Productive mercury adsorption is also possible by the oil shale particles as a result of residual fixed-carbon and other observed mercury capture sorbent properties. Sorption properties were found to be a function particle heating rate, peak particle temperature, residence time, and gas-phase stoichmetry. High surface area sorbents with high calcium reactivity and with some adsorbent fixed/activated carbon can be produced in the corresponding reaction zones that exist in a standard pulverized-coal or in a fluidized-bed combustor.

China Oil and Gas Market Assessment

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

Oil and gas in the environment

International Nuclear Information System (INIS)

1998-01-01

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.

Two series of experiments of hydroprocessing of light gas oil - rape oil mixtures were carried out. The reactor feed was composed of raw material: first series - 10 wt.% rape oil and 90 wt.% of diesel oil; second series - 20 wt.% rape oil and 80 wt.% of diesel oil. Hydroprocessing of both mixtures was performed with the same parameter sets, temperature (320, 350 and 380 C), hydrogen pressure 3 and 5 MPa, LHSV = 2 h{sup -} {sup 1} and hydrogen feed ratio of 500 Nm{sup 3}/m{sup 3}. It was stated that within limited range it is possible to control vegetable oil hydrogenolysis in the presence of light gas oil fraction (diesel oil boiling range) through the proper selection of the process parameters. Hydrogenolysis of ester bonds and hydrogenation of olefinic bonds in vegetable oils are the main reactions in the process. Basic physicochemical properties of the obtained hydroprocessed products are presented. (author)

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.

Hamm, Keith

1992-01-01

The two major political events of 1991 produced a much less dramatic reaction in the global oil industry than might have been expected. The economic dislocation in the former USSR caused oil production to fall sharply but this was largely offset by a concurrent fall in demand. Within twelve months of the invasion of Kuwait, crude oil prices had returned to their pre-invasion level; there was no shortage of supply due to the ability of some producers to boost their output rapidly. Details are given of world oil production and developments in oil demand. Demand stagnated in 1991 due to mainly to the economic chaos in the former USSR and a slowdown in sales in the USA; this has produced problems for the future of the refining industry. By contrast, the outlook for the natural gas industry is much more buoyant. Most clean air or carbon emissions legislation is designed to promote the use of gas rather than other hydrocarbons. World gas production rose by 1.5% in 1991; details by production on a country by country basis are given. (UK)

Middle East oil and gas

International Nuclear Information System (INIS)

1995-01-01

This study is intended to shed light on structural changes occurring in six Middle East countries (Iran, Iraq, Kuwait, Qatar, Saudi Arabia and the United Arab Emirates) that can be expected to have a significant impact on their oil and gas industry. These six countries provide 42% of the world's traded crude oil, on which Member countries of the International Energy Agency (IEA) are increasingly dependent. They also contain about 65% and 30% of the world's proven oil and natural gas reserves, respectively, and command a strategic location between Europe and Asia. The Middle East has been one of the most volatile parts of the world where war, revolution and embargoes have caused major upheavals that have led to oil supply disruptions. The oil resources of all six countries were initially developed by international oil companies and all are members of the Organization of the Petroleum Exporting Countries (OPEC). In 1994, their crude oil production capacity was about 23 million barrels per day (mbd) and is planned to expand to about 28 mbd by the year 2000. Revenue from the sale of oil accounts for more than 80% of each nation's total exports and about 75% of each government's income. The objectives of this study are: to detail their announced oil and gas development plans, to describe the major trends occurring in these countries, to outline the government responses to the trends, and to analyse the impact of government policies on oil and gas development.

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

Directory of Open Access Journals (Sweden)

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.

Petronas or Petroliam Nasional Berhad was established on 17 August 1974 as the national petroleum corporation of Malaysia. The Petroleum Development Act, passed by the Malaysian Parliament in October of that same year, vested in Petronas the entire ownership of all oil and natural gas resources in the country. These resources are considerable and Malaysia is poised to become one of the major petrochemical producers in the region. This report outlines the extent of oil, gas and petrochemicals production in Malaysia, lists companies holding licences and contracts from Petronas and provides a directory of the Malaysian oil industry.

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.

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

The migration of gas from oil and gas formations to the surface is a problem that greatly affects those surface areas where human activity exists. Underground gas storage facilities and oil fields have demonstrated a long history of gas migration problems. Experience has shown that the migration of gas to the surface creates a serious potential risk of explosion, fires, noxious odors and potential emissions of carcinogenic chemicals. These risks must be seriously examined for all oil and gas operations located in urban areas. This paper presents the mechanics of gas migration, paths of migration and a review of a few of the risks that should be considered when operating a gas facility in an urban area. The gas can migrate in a continuous or discontinuous stream through porous, water-filled media to the surface. The primary force in this migration of gas is the difference between specific weights of gas and water

One of the methods to contain the diesel oil spill is the application of materials polymeric sorbents and the polyurethane is an option of porous sorbents. In this way, the objective of this study was to evaluate the use of polyurethane composites derivative of castor oil reinforced with palm fibers to sorption of diesel oil and compare with pure polyurethane. The composites were reinforced with 5 to 20% w/w of fibers. Subsequently, the sorption capacity of the composite in function of inserted fiber content in the matrix was analyzed. The physical and morphological characteristics were evaluated by scanning electron microscopy techniques (SEM) and diffraction X-ray (XRD) and the contact angle. The results showed that the composite with 20% w /w showed higher sorption capacity oil diesel compared to pure PU and other composites this fact was due to the heterogeneity of the pores and dispersion of fiber in the matrix.

Controlled PVTS oil and gas production stimulation system

Energy Technology Data Exchange (ETDEWEB)

Ospina-Racines, E

1970-02-01

By completing oil- or gas-producing wells according to the PVTS method and energizing the flow of the oil-gas fluids in the reservoir with a small horse-power gas compressor at the wellhead, the following oil and gas production features are attained: (1) Original reservoir story energy conditions are restored, improved, used, and conserved while producing oil and/or gas. (2) The flow of oil or gas in the pay formation to the well bore is stimulated by gas compressor energy, outside of the reservoir system. The pressure drawdown is developed by gas-compressor energy in the well casing and not in the pay formation. (3) The stored energy of the reservoir is conserved while producing oil or gas. The potential energy (pressure) of the reservoir can be used to advantage up to bubble point of the virgin crude. (4) Producible reserves are increased from 4-to 5-fold by the conservation of reservoir energy. Present-day primary oil production practice yields a maximum of 20% of the oil in place by depleting the original reservoir energy. The PVTS system will yield over 80% + of oil in place. (5) Producible gas reserves can be increased greatly by establishing a low abandonment pressure at will. The principal features of the PVTS well mechanism and energy injection method are illustrated by a schematic diagram.

After the oil crises, Malaysia unveiled its four fuel diversification policy in the late 1970s towards utilization of gas, oil, coal and hydro. This was to ensure adequate and continuous energy supply for driving economic development and to cushion itself against impact of possible future fluctuations in oil prices. The primary energy supply in 1978 was predominantly oil based, consisting of 75.5% oil. As a result of this diversification policy, the oil component was reduced to about 51.8% in 1988. Due to its inherent ability to adapt and adjust to different fuels, the power sector played a crucial role in this massive shift away from oil. For the corresponding period, the oil component in the electricity generation input mix has decreased from 86.7% oil to 47.4%. Malaysia is endowed with substantial natural gas reserves amounting to 52.5 trillion cubic feet. Gas, therefore constitutes a natural and attractive option for the power sector in diversifying into non-oil indigenous energy resources, as the country's hydro potential has its limitations and the available proven coal reserves are relatively small. The paper addresses the past and current status and issues involved in displacing oil by gas for the power sector. These include the economic, technological and pricing aspects of natural gas development and issues pertaining to power system development. Future gas utilization strategies include the conversion of existing oil-fired plants to gas-fired, and the plant-up of gas turbines and the efficient combined cycle plants to meet the load requirements. These strategies are assessed from the viability and security perspective of increased gas utilization. Oil will continue to be displaced, but the extent to which gas will increase its share in power production is dependent on numerous factors ranging from its economics to supply security

Yukon's common oil and gas regime

Love, B.

1998-01-01

The Yukon's common oil and gas regime was developed in partnership with First Nations and it sets out the rules that will apply throughout the Yukon and on Yukon and First Nation lands. While separate and distinct, it conforms with and is compatible with other government systems and regimes. The major elements of the common regime include the Oil and Gas Act, regulations, policies, processes and agreements. The specific opportunities that are available in each phase of oil and gas development in the Yukon are described, with a map showing all basins, reserves and sites of current oil and gas activity. The Yukon has eight potential oil and gas basins: North Coast, Old Crow, Kandik, Eagle Plain, Peel Plateau, Bonnet Plume, Whitehorse Trough, and Liard Plateau. Only three of the eight, the Liard Plateau, Whitehorse Trough and Eagle Plain, have been explored. No wells have been drilled in several of Yukon's basins. Factors influencing economic opportunities in the Territory are also described, including: (1) international events and energy markets, (2) North American gas markets, (3) environmental factors, (4) competitiveness of the Yukon regime, and (5) the commitment of industry resources. 4 figs

New oil and gas incentives in Saskatchewan

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

During the last decade, Algeria, Egypt and Libya have improved their fiscal terms for oil and gas development to attract more investment in this area. As a group, the three countries are implementing plans to increase crude oil production capacity 16 % from 3.15 million barrels per day (Mb/d) in 1995 to 3.65 Mb/d in the year 2000. Natural gas liquid are also being developed and their production capacity is planned to increase 30 % to 0.82 Mb/d in 2000. Concurrently, natural gas production capacity is being expanded about 50 % by 200 and natural gas exporting capacity should see a 92 % increase in 2000 over 1995 levels in short, the North Africa hydrocarbon producers are rapidly expanding their production and export capacity of gaseous and liquid hydrocarbons. This is the first IEA study to focus on North Africa. It shows how changing hydrocarbon legislation or production sharing agreements can result in changes in crude oil and natural gas production capacity. Much of the expansion outlined in this study is being guided by international oil companies attracted by the improved fiscal terms

This report documents studies on the effects of gas sorption on coal, with the intent of eventually evaluating how sorption and strain affect permeability. These studies were, carried out at the University of Alabama during the period from 1989 through 1992. Two major experimental methods were developed and used. In the strain experiments, electronic strain gauges were attached to polished blocks of coal in order to measure linear and volumetric swelling due to gas sorption. The effects of bedding plane orientation, of gas type, and of coal type were investigated. In the gravimetric experiment the weight of small samples of coal was measured during exposure to high pressure gases. Sample measurements were corrected for buoyancy effects and for sample swelling, and the results were plotted in the form of Langmuir isotherms. Experiments were conducted to determine the effect of grain size, coal type, moisture, and of sorbant gas. The advantage of this method is that it can be applied to very small samples, and it enabled comparison liptinite versus vitrinite concentrates, and kerogen rich versus kerogen depleted oil shales. Also included is a detailed discussion of the makeup of coal and its effect on gas sorption behavior.

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.

Gas Sorption, Diffusion and Permeation in a Polymer of Intrinsic Microporosity (PIM-7)

KAUST Repository

Alaslai, Nasser Y.

2013-05-08

The entire world including Saudi Arabia is dependent on natural gas to provide new energy supplies for the future. Conventional ways for gas separation are expensive, and, hence, it is very important to reduce the cost and lower the energy consumption. Membrane technology is a relatively new separation process for natural gas purification with large growth potential, specifically for off-shore applications. The economics of any membrane separation process depend primarily on the intrinsic gas permeation properties of the membrane materials. All current commercial membranes for natural gas separation are made from polymers, which have several drawbacks, including low permeability, moderate selectivity, and poor stability in acid gas and hydrocarbon environments. The recent development of polymeric materials called “polymers of intrinsic microporosity” (PIMs) provide a new class of high-performance membrane materials that are anticipated to be used in natural gas separation processes including, but not limited to, acid gas removal and separation of hydrocarbons from methane. PIM-7 is an excellent example of a material from the PIMs series for gas separation. It was selected for this work since it has not been extensively tested for its gas permeation properties to date. Specifically, sorption and mixed-gas permeation data were not available for PIM-7 prior to this work. Sorption isotherms of N2, O2, CH4, CO2, C2H6, C3H8 and n-C4H10 were determined over a range of pressures at 35 oC for PIM-7 using a custom-designed dual-volume pressure decay system. Condensable hydrocarbon gases, such as C3H8 and n-C4H10, show significantly higher solubility than the other less condensable gas of the test series due to their high affinity to the polymer matrix. Dual-mode sorption model parameters were determined from the sorption isotherms. Henry’s law solubility, Langmuir capacity constant and the affinity constant increased with gas condensability.

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.

Co-processing of standard gas oil and biocrude oil to hydrocarbon fuels

International Nuclear Information System (INIS)

Agblevor, Foster A.; Mante, O.; McClung, R.; Oyama, S.T.

2012-01-01

The major obstacle in thermochemical biomass conversion to hydrocarbon fuels using pyrolysis has been the high oxygen content and the poor stability of the product oils, which cause them to solidify during secondary processing. We have developed a fractional catalytic pyrolysis process to convert biomass feedstocks into a product termed “biocrude oils” (stable biomass pyrolysis oils) which are distinct from unstable conventional pyrolysis oils. The biocrude oils are stable, low viscosity liquids that are storable at ambient conditions without any significant increases in viscosity; distillable at both atmospheric pressure and under vacuum without char or solid formation. About 15 wt% biocrude oils containing 20–25% oxygen were blended with 85 wt% standard gas oil and co-cracked in an Advanced Catalyst Evaluation (ACE™) unit using fluid catalytic cracking (FCC) catalysts to produce hydrocarbon fuels that contain negligible amount of oxygen. For the same conversion of 70% for both the standard gas oil and the biocrude oil/gas oil blends, the product gasoline yield was 44 wt%, light cycle oil (LCO) 17 wt%, heavy cycle oil (HCO) 13 wt%, and liquefied petroleum gas (LPG) 16 wt%. However, the coke yield for the standard gas oil was 7.06 wt% compared to 6.64–6.81 wt% for the blends. There appeared to be hydrogen transfer from the cracking of the standard gas oil to the biocrude oil which subsequently eliminated the oxygen in the fuel without external hydrogen addition. We have demonstrated for the first time that biomass pyrolysis oils can be successfully converted into hydrocarbons without hydrogenation pretreatment. -- Highlights: ► The co-processed product had less than 1% oxygen content and contained biocarbons determined by 14 C analysis. ► The co-processing did not affect the yields of gasoline, LCO, and HCO. ► First demonstration of direct conversion of pyrolysis oils into drop-in hydrocarbon fuels.

Canadian oil and gas survey 1998

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

Oil and gas fiscal regime review

International Nuclear Information System (INIS)

1993-04-01

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

This report presented some quick facts about oil and gas pipelines in Turkey and presented opportunities for trade. The key players and customers in the oil and gas sector were described along with an export check list. Turkey is looking into becoming an energy bridge between oil and gas producing countries in the Middle East, Central Asia and Europe. The oil and gas sectors are dominated by the Turkish Petroleum Corporation, a public enterprise dealing with exploration and production, and the State Pipeline Corporation which deals with energy transmission. They are also the key buyers of oil and gas equipment in Turkey. There are several pipelines connecting countries bordering the Caspian Sea. Opportunities exist in the areas of engineering consulting as well as contracting services for oil and gas pipeline transmission and distribution. Other opportunities lie in the area of pipeline construction, rehabilitation, materials, equipment, installation, and supervisory control and data acquisition (SCADA) systems. Currently, the major players are suppliers from Italy, Germany, France, United States and Japan. Turkey has no trade barriers and imported equipment and materials are not subjected to any restriction. The oil and gas market in Turkey expected in increase by an average annual growth rate of 15 per cent from 2001 to 2003. A brief description of pipeline projects in Turkey was presented in this report along with a list of key contacts and support services. 25 refs., 1 append

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

Directory of Open Access Journals (Sweden)

Jianjun Chen

2016-05-01

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 �

Grand canonical Monte Carlo (GCMC) simulations were performed to investigate CO2 and H2 sorption in an rht-metal-organic framework (MOF) that was synthesized with a ligand having a nitrogen-rich trigonal core through trisubstituted triazine groups and amine functional groups. This MOF was synthesized by two different groups, each reporting their own distinct gas sorption measurements and crystal structure. Electronic structure calculations demonstrated that the small differences in the atomic positions between each group\\'s crystal structure resulted in different electrostatic parameters about the Cu2+ ions for the respective unit cells. Simulations of CO2 sorption were performed with and without many-body polarization effects and using our recently developed CO2 potentials, in addition to a well-known bulk CO2 model, in both crystallographic unit cells. Simulated CO2 sorption isotherms and calculated isosteric heats of adsorption, Qst, values were in excellent agreement with the results reported previously by Eddaoudi et al. for both structures using the polarizable CO2 potential. For both crystal structures, the initial site for CO2 sorption were the Cu 2+ ions that had the higher positive charge in the unit cell, although the identity of this electropositive Cu2+ ion was different in each case. Simulations of H2 sorption were performed with three different hydrogen potentials of increasing anisotropy in both crystal structures and the results, especially with the highest fidelity model, agreed well with Eddaoudi et al.\\'s experimental data. The preferred site of H 2 sorption at low loading was between two Cu2+ ions of neighboring paddlewheels. The calculation of the normalized hydrogen dipole distribution for the polarizable model in both crystal structures aided in the identification of four distinct sorption sites in the MOF, which is consistent to what was observed in the experimental inelastic neutron scattering (INS) spectra. Lastly, while the

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)

Levine, J.R.; Johnson, P.W.

1992-11-30

This report documents studies on the effects of gas sorption on coal, with the intent of eventually evaluating how sorption and strain affect permeability. These studies were, carried out at the University of Alabama during the period from 1989 through 1992. Two major experimental methods were developed and used. In the strain experiments, electronic strain gauges were attached to polished blocks of coal in order to measure linear and volumetric swelling due to gas sorption. The effects of bedding plane orientation, of gas type, and of coal type were investigated. In the gravimetric experiment the weight of small samples of coal was measured during exposure to high pressure gases. Sample measurements were corrected for buoyancy effects and for sample swelling, and the results were plotted in the form of Langmuir isotherms. Experiments were conducted to determine the effect of grain size, coal type, moisture, and of sorbant gas. The advantage of this method is that it can be applied to very small samples, and it enabled comparison liptinite versus vitrinite concentrates, and kerogen rich versus kerogen depleted oil shales. Also included is a detailed discussion of the makeup of coal and its effect on gas sorption behavior.

Gas and Oil Flow through Wellbore Flaws

Science.gov (United States)

Hatambeigi, M.; Anwar, I.; Reda Taha, M.; Bettin, G.; Chojnicki, K. N.; Stormont, J.

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.

Full Text Available This article analyzes the influence of the economic sanctions imposed from the USA and the EU and oil prices reduction on the oil and gas companies and the directions of diversification of their activity as a method of management of price risks are considered. In the modern dynamic and quickly developing world, in the conditions of globalization and market economy, the oil and gas companies are affected by various risks which can exert negative impact on production and financial results. Risks can arise in absolutely various spheres, beginning from natural and technological hazards, and finishing with price risks. Sharp reduction of oil prices and decrease in demand for energy resources in the world markets, first of all in the European countries, input of financial or technological sanctions from the USA and Europe against Russia in 2014 has caused necessity of search a new more effective methods of price risks management of the oil and gas company. The methods of price risk management include the creation of commodity reserves, the establishment of a reserve fund, long-term contracts, subsidies from the state and the diversification of activities. The most effective it is possible to offer diversification of oil and gas companies' activity. It is expedient to carry out diversification of oil and gas companies' activity in such directions as geographical diversification of the oil, oil products and gas realization directions, geographical diversification of oil and gas companies' purchasing activity, diversification of oil, oil products and gas transportation ways, diversification of oil and gas companies' business. This approach allows to expand the activities of the oil and gas companies and create additional ways to generate revenue and enhance efficiency of oil and gas companies.

This report deals with the use of oil-, natural gas and liquefied petroleum gas (LPG) during 1993. Information about markets and technical environmental questions are also given. Data have been collected from earlier reports, information given by different persons and statistics from SCB and SPI. The import of crude oil increased from 16,8 million tons in 1992 to 17,8 million tons in 1993. The import of oil products decreased by 0,9 million tons down to 6,7 million tons in the same period. During this period, the import of natural gas increased by 9%, a total of 817 million cubic meters. The import of LPG was 748000 tons in 1993, which is 61000 tons less compared to the import of 1992. The production in Sweden for 1993 was 290000 tons, the same level as the level reached in 1992. The export of LPG increased from 107000 tons to 138000 tons during this period. In January 1993, legislative changes were made concerning energy taxes and carbon dioxide penalty taxes. The rate of the latter was increased from 25 to 32 oere per kilogram of carbon dioxide released in the atmosphere. For industry and greenhouse production, the penalty rate is only 25% or 8 oere per kilogram of carbon dioxide. From 1995 to 1998, yearly increases in the rate of energy taxes and carbon dioxide penalty taxes will be based on the consumer price index. Taxes will be increased by 4% in 1994. Due to changes in energy taxes, the consumption of LPG decreased in 1993. Earlier, many industries had changed from oil to LPG but now have changed back to oil. 8 figs, 17 tabs

Medium-Term Oil and Gas Markets 2011

2011-06-16

Oil and gas markets have been marked by an increased divergence in recent months. On the one hand, oil market developments have generated an unpleasant sense of deja vu: rapid demand growth in emerging markets eclipsed sluggish supply growth to push prices higher even before the conflict in Libya tightened supplies still further. Oil prices around $100/bbl are weighing down on an already-fragile macroeconomic and financial situation in the OECD, pressuring national budgets in the non-OECD and causing price inflation of other commodities, as well as political concerns about speculation. There is an uncanny resemblance to the first half of 2008. On the other hand, in the world of natural gas an amazing disconnect has developed as demand recovered to well above pre-financial-crisis levels in most major regions. Gas markets have tightened in Europe and Asia, where prices are about twice the level seen in the United States, as the unconventional gas revolution is in full swing. From the upstream implications of the Arab Spring to the macroeconomic consequences of the eurozone crisis, energy markets are experiencing one of the most uncertain periods in decades. This publication provides a comprehensive outlook for oil and gas fundamentals through 2016. The oil market analysis covers demand developments on a product-by-product and key-sector basis, as well as a detailed bottom-up assessment of upstream and refinery investments, trade flows, oil products supply and OPEC spare capacity. The gas market analysis offers a region-by-region assessment of demand and production, infrastructure investment, price developments and prospects for unconventional gas. It also examines the globalising LNG trade.

Oil and Gas Emergency Policy: Germany 2012 update

2012-07-01

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

Full Text Available One of the primary concerns for investment in oil and gas projects is to have a comprehensive understanding on different issues associated with this industry. The industry is mainly influ-enced by the price of oil and gas and in some events, many production units have been forced to shut down solely because of low price of oil and gas. Environmental issues are other important factors, which may put pressure on Canada’s political affairs since the country has strong com-mitment to reduce green gas effect. In this paper, we introduce a multi-criteria decision making method, which helps us rank different projects in terms of investment. The proposed study con-siders different investment factors including net present value, rate of return, benefit-cost analy-sis and payback period along with the intensity of green gas effects for ranking the present oil and gas projects in Canada.

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

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 market developments in Turkey

Turkey's strategic location makes it a natural 'energy bridge' between major oil and gas producing areas in the Middle East and Caspian Sea regions on one hand and consumer markets in Europe on the other. Oil consumption has increased in recent years in Turkey, and this trend is expected to continue, with growth of 2-3% annually in coming years. The annual oil consumption of the country is around 31.3 million tons, while 83% of total consumption is supplied from imports and only 17% is supplied from indigenous production. Oil provides around 43% of Turkey's total energy requirements, but its share is declining (as the share of natural gas rises). On the other hand, due to diversification efforts of energy sources, use of natural gas was newly introduced into the Turkish economy in 1987 and has been growing rapidly. Turkey's natural gas reserves seem limited and current gas production in the country meets 2.8% of domestic consumption requirements. The annual natural gas consumption of Turkey is around 14.7 billion m 3 and is assumed to increase by 12% per annum. Turkish natural gas use is projected to increase dramatically in coming years, with the prime consumers expected to be industry and power plants. Turkey has chosen natural gas as the preferred fuel for the massive amount of new power plant capacity to be added in coming years. (Author)

Documentation of the Oil and Gas Supply Module (OGSM)

NONE

1998-01-01

The purpose of this report is to define the objectives of the Oil and Gas Supply Model (OGSM), to describe the model`s basic approach, and to provide detail on how the model works. This report is intended as a reference document for model analysts, users, and the public. Projected production estimates of US crude oil and natural gas are based on supply functions generated endogenously within National Energy Modeling System (NEMS) by the OGSM. OGSM encompasses domestic crude oil and natural gas supply by both conventional and nonconventional recovery techniques. Nonconventional recovery includes enhanced oil recovery (EOR), and unconventional gas recovery (UGR) from tight gas formations, Devonian/Antrim shale and coalbeds. Crude oil and natural gas projections are further disaggregated by geographic region. OGSM projects US domestic oil and gas supply for six Lower 48 onshore regions, three offshore regions, and Alaska. The general methodology relies on forecasted profitability to determine exploratory and developmental drilling levels for each region and fuel type. These projected drilling levels translate into reserve additions, as well as a modification of the production capacity for each region. OGSM also represents foreign trade in natural gas, imports and exports by entry region. Foreign gas trade may occur via either pipeline (Canada or Mexico), or via transport ships as liquefied natural gas (LNG). These import supply functions are critical elements of any market modeling effort.

Two main development could gradually modify these traditional features of natural gas markets and prices. First, environmental pressures and the tightening of emission standards and of the quality specifications for fuels should work in favor of natural gas. Second the increasing distance of resources in relation to the major consuming zones should bring about a considerable development of international natural gas trade. International expansion should mark the development of the gas industry in the coming decades. This evolution will give natural gas an importance and a role appreciably closer to those of oil on the world energy scene. But it is obvious that such a development can come about only at the cost of considerable investments for which the economic viability is and will remain dependent on the level of the prices of natural gas as the inlet to its consuming markets. This paper attempts to answer the questions: Will these markets accept a new scale of value for gas in relation to other fossil fuels, including oil, which will take into account new environmental constraints and which will be able to fulfill the formidable financial needs of the gas industry in the coming decades?

Risk factors in stock returns of Canadian oil and gas companies

International Nuclear Information System (INIS)

Sadorsky, P.

2001-01-01

This paper uses a multifactor market model to estimate the expected returns to Canadian oil and gas industry stock prices. Results are presented to show that exchange rates, crude oil prices and interest rates each have large and significant impacts on stock price returns in the Canadian oil and gas industry. In particular, an increase in the market or oil price factor increases the return to Canadian oil and gas stock prices while an increase in exchange rates or the term premium decreases the return to Canadian oil and gas stock prices. Furthermore, the oil and gas sector is less risky than the market and its moves are pro-cyclical. This suggests that Canadian oil and gas stocks may not be a good hedge against inflation

Learning through Oil and Gas Exploration

DEFF Research Database (Denmark)

Levitt, Clinton J.

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

Oil and gas leasing/production program

International Nuclear Information System (INIS)

Heimberger, M.L.

1992-01-01

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

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)

Oil and Gas Emergency Policy: Turkey 2013 update

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

Although coal is the dominant energy source in China, accounting for some 70% of the country's Total Energy Consumption (TEC) in 2009, oil and gas are also essential energy sources. Despite strong growth in consumption of oil, its share of TEC fell from 22% in 2000 to 18% in 2009, as coal use rose even faster to meet burgeoning demand for electricity. A strong policy push boosted natural gas supplies, particularly to residential customers, so that the share of natural gas doubled from 2% in 2000 to 4% in 2009. China is one of the important oil and natural gas producing counties in the world. In 2010, China's crude oil production exceeded 4 million barrels per day (mb/d). However, with strong and sustained economic growth, its demand for oil has also increased, from 4.6 mb/d in 2000 to over 8 mb/d in 2009. In the New Policy Scenario (NPS) of the IEA World Energy Outlook (WEO) 2011, China's primary oil demand rises to 12.2 mb/d in 2020. Although China is now the world's fifth largest oil producer, the country has been a net oil importer since 1993. In 2011, China imported over 5 mb/d of crude oil, accounting for about 54% of its total demand. More than 50% of the total crude oil imports came from counties of the Middle East. To prevent a potential shock to the economy caused by an oil supply disruption, the Chinese government has been steadily pushing building an oil stock reserve system. China has completed four stockpiling facilities with a capacity of around 103 mb in the first phase of its Strategic Petroleum Reserve (SPR) plan, and has begun construction of its second phase, which comprises eight storage sites that will reportedly have a combined capacity of around 207 mb. Among them, two sites were completed in the second half of 2011 and the Tianjin site is reportedly set to be completed in 2012. According to unofficial reports, the remaining four SPR-II sites are expected to become operational by 2013. The third phase is expected to boost

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.

Prospects for oil and gas

International Nuclear Information System (INIS)

Laherrere, J.

2011-01-01

It was five years ago, in January 2006, that Futuribles devoted a major special issue (no. 315) to energy prospects and the greenhouse effect. That was already a time of great concern about this question and several articles offered analyses of the gloomy prospects for the development of energy resources and the issues around climate change. Among these, an article by Jean Laherrere outlined the prospects for oil resources, showing the extent to which information in this area was disparate, unreliable and even questionable, being often highly political. As one of the more pessimistic writers on the question, Laherrere reminded us of the imminence of 'peak oil' (the prelude to a decline in global oil production) and the need to re-think our styles of consumption to adapt to a new age in which, as energy becomes scarcer, it will be increasingly expensive. Five years later, Jean Laherrere returns to the columns of Futuribles on the occasion of a new special issue on energy and the climate, to update us on the global prospects for oil and gas production. He begins by recalling how politically slanted and unreliable information in this area can be, depending on its source, the units of measurement employed etc. He stresses, too, that in the view of many experts peak oil was reached in 2006 and the situation is currently plateau-ing, just ahead of a decline in oil production (gradual or sudden, depending on whether measures of economic constraint are implemented). For its part, gas production should peak around 2025-2030. Jean Laherrere specifies what reserves remain, how these are currently exploited and marketed, and the prospects that ensue in the longer term (he also shows how wrong gas-price forecasts have been in the past). As he stresses, in conclusion, with both oil and gas we must be aware that the world does not have infinite resources and, since the alternatives do not allow us, at the moment, to make up for future energy-resource shortages, it is for

Conference Proceedings: Structuring oil and gas property transactions

International Nuclear Information System (INIS)

1999-01-01

The 12 presentations at this conference dealt with issues concerning the legal aspects of oil and gas property transaction agreements. Several issues regarding sales and purchase negotiations of oil and gas property are reviewed and some of the basic principles of contract law are explained. Advantages, disadvantages and opportunities of structuring oil and gas property acquisitions, as well as their tax consequences are also identified. The issue of risk assessment regarding environmental consequences and how public concerns regarding the state of the environment has had an impact on oil and gas transactions, is addressed. Interest in this topic stems from the fact that improved enforcement of existing laws regarding the environment can potentially make purchasers liable for significant costs associated with remediation or clean-up of contaminated properties. refs., tabs., figs

Quantitative calculation of GOR of complex oil-gas-water systems with logging data: A case study of the Yingdong Oil/Gas Field in the Qaidam Basin

Sima Liqiang

2014-12-01

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 sorption of surfactants in bentonite clay can occur through the mechanism of adsorption and absorption, this being a very supple phenomenon according clay and surfactant utilized. Thus the more surfactant sorbed at the organoclay it becomes, and can be used in various applications, including in oil drilling fluid. This study aimed to correlate the sorption of surfactants with the rheological properties of non-aqueous fluids (oil base). In organophilization process was used Bentongel clay which had its concentration varied from 3.16 to 7.16% by weight of clay. It was used to organophilization an ionic surfactant Praepagem WB with 75% of active matter, where its concentration ranged from 127-181 mEq. After organophilizated the clays were filtered, dried in an oven for 48 hours and passed in ABNT sieve No. 200, to be so characterized. Sorption was calculated from mathematical equations. Non-aqueous fluids were prepared according to standard Petrobras (EP-1EP-00023A) for rheological testing. Correlating the sorption of surfactant, and the rheological properties of non-aqueous fluid, obtained satisfactory results where observed through the scatter plots there is a strong correlation between the variables sorption and apparent viscosity, it should also be noted that the viscosity is a variable which increases with an increase in sorption, confirming that the surfactant concentration influences the viscosity.

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.

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

Science.gov (United States)

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

China's energy security: Oil and gas

International Nuclear Information System (INIS)

Wu, Kang

2014-01-01

China is currently the largest energy consuming country in the world. Until the early 1990s, China had long been a net energy exporter. The country became a net oil importer in 1993, the first time since the 1960s. For China, energy security first means oil supply security. China turned into a net natural gas importer in 2007 and then a net coal importer in 2009. In other words, China is now a net importer of all three types of fossil energy—oil, natural gas, and coal. In the context of rising oil imports and implementation of China's 12th Five-Year Program from 2011 to 2015, this paper examines China's energy security strategies with a focus on three leading elements, namely overseas oil investment, strategic petroleum reserves (SPR)and unconventional gas development. Our findings suggest that the Chinese government has promoted overseas investment strongly; its SPR program has been established though the progress for Phase II has been slower than expected and the government intends to boost the unconventional gas sector development. However, the challenges are enormous as well. As for future research, other elements for each dimension of energy security should be reviewed to reach a comprehensive conclusion about how well China has done and what steps are needed to move forward. - Highlights: • Identified China's key energy security strategies during the 12th Five-Year Program (FYP) and previous FYPs. • Provided a unique insight into China's rising oil imports. • Reviewed China's overseas oil and gas investment as a key energy security measure. • Assessed China's strategic petroleum reserves program and the future growth. • Provided a comprehensive coverage of China's unconventional gas development, including both coal-bed methane and shale gas

In cooperation with The Colorado Oil and Gas Conservation Commission, researchers at Colorado State University performed area noise monitoring at 23 oil and gas sites throughout Northern Colorado. The goals of this study were to: (1) measure and compare the noise levels for the different phases of oil and gas development sites; (2) evaluate the effectiveness of noise barriers; and (3) determine if noise levels exceeded the Colorado Oil and Gas Conservation Commission noise limits. The four phases of oil and gas development include drilling, hydraulic fracturing, completion and production. Noise measurements were collected using the A- and C-weighted sound scales. Octave band analysis was also performed to characterize the frequency spectra of the noise measurements.  Noise measurements were collected using noise dosimeters and a hand-held sound-level meter at specified distances from the development sites in each cardinal direction. At 350 ft (107 m), drilling, hydraulic fracturing, and completion sites without noise barriers exceeded the maximum permissible noise levels for residential and commercial zones (55 dBA and 60 dBA, respectively). In addition, drilling and hydraulic fracturing sites with noise barriers exceeded the maximum permissible noise level for residential zones (55 dBA). However, during drilling, hydraulic fracturing, and completion operations, oil producers are allowed an exception to the noise permissible limits in that they only must comply with the industrial noise limit (80 dBA). It is stated in Rule 604.c.(2)A. that: "Operations involving pipeline or gas facility installation or maintenance, the use of a drilling rig, completion rig, workover rig, or stimulation is subject to the maximum permissible noise levels for industrial zones (80dBA)." [8] Production sites were within the Colorado Oil and Gas Conservation Commission permissible noise level criteria for all zones. At 350 ft (107 m) from the noise source, all drilling

Using Polymer Alternating Gas to Enhance Oil Recovery in Heavy Oil

Yang, Yongzhi; Li, Weirong; Zhou, Tiyao; Dong, Zhenzhen

2018-02-01

CO2 has been used to recover oil for more than 40 years. Currently, about 43% of EOR production in U.S. is from CO2 flooding. CO2 flooding is a well-established EOR technique, but its density and viscosity nature are challenges for CO2 projects. Low density (0.5 to 0.8 g/cm3) causes gas to rise upward in reservoirs and bypass many lower portions of the reservoir. Low viscosity (0.02 to 0.08 cp) leads to poor volumetric sweep efficiency. So water-alternating-gas (WAG) method was used to control the mobility of CO2 and improve sweep efficiency. However, WAG process has some other problems in heavy oil reservoir, such as poor mobility ratio and gravity overriding. To examine the applicability of carbon dioxide to recover viscous oil from highly heterogeneous reservoirs, this study suggests a new EOR method--polymer-alternating gas (PAG) process. The process involves a combination of polymer flooding and CO2 injection. To confirm the effectiveness of PAG process in heavy oils, a reservoir model from Liaohe Oilfield is used to compare the technical and economic performance among PAG, WAG and polymer flooding. Simulation results show that PAG method would increase oil recovery over 10% compared with other EOR methods and PAG would be economically success based on assumption in this study. This study is the first to apply PAG to enhance oil recovery in heavy oil reservoir with highly heterogeneous. Besides, this paper provides detailed discussions and comparison about PAG with other EOR methods in this heavy oil reservoir.

Wage Inequality and Violent Protests in Oil/Gas Producing Countries

Science.gov (United States)

Nuraliyev, Nurlan

This work examines contrasting claims made by academic scholars on the relationship between income inequality and political discontent. Does income inequality directly cause social unrest or is this relationship conditional on the level of democratic development? Using the data from 55 oil/gas producing countries between 2010-2013, the author finds: 1) income disparity between an average income per capita of local population and an average income of foreign labor employed in the oil/gas industry results in higher number of violent protests in more democratic oil/gas producing societies; 2) wage disparity between local and foreign labor in the oil/gas industry is associated with higher number of protests in this industry in more democratic oil/gas producing states.

The Appalachian/Illinois Basin Directors is a group devoted to increasing communication among the state oil and gas regulatory agencies within the Appalachian and Illinois Basin producing region. The group is comprised of representatives from the oil and gas regulatory agencies from states in the basin (Attachment A). The directors met to discuss regulatory issues common to the area, organize workshops and seminars to meet the training needs of agencies dealing with the uniqueness of their producing region and perform other business pertinent to this area of oil and gas producing states. The emphasis of the coordinated work was a wide range of topics related to environmental compliance for natural gas and oil exploration and production.

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

Oil and gas operational and policy issues in the UK

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)

Oil and gas in China: The door opens wider to international oil companies

International Nuclear Information System (INIS)

Tao, Wang

1993-01-01

This paper reviews new incentives offered by the China National Petroleum Corporation to help develop China's oil and gas fields. The initial offer for bids by foreign investors is for exploration and joint development contracts for western China's Tarim basin. However, the expansion to other basins and areas of China is well underway. It also discusses a pipeline project which will be connect the western China oil and gas fields with the eastern markets, approximately 2,200 miles. A historical review of the oil and gas production and utilization of China is presented along with forecasts of future production. It also provides estimates of gas and oil reserves and information on enhanced recovery techniques used to maintain a stable production level. The second half of the paper is an interview with Dr. Wang Tao, a PhD graduate of Moscow's Petroleum Institute, and president of the China National Petroleum Corporation. He reviews the government policies with regards to foreign investment in his country

Profiler : Canadian oil and gas : the First Nations : building successful partnerships

Energy Technology Data Exchange (ETDEWEB)

Anon.

2010-05-15

Canada's petroleum and natural gas is often produced in remote areas where the majority of the population is Aboriginal. Many First Nations and Metis communities are now playing an active role in Canada's oil and gas industry. Aboriginal-owned companies have earned more than $2.6 billion in the oil sands region since 1999. In 2007, the value of contracts between Alberta oil sands companies and Aboriginal companies was estimated at $606 million. This special supplement discussed First Nations partnerships in the oil and gas industry. Articles in the supplement presented new employment, training and partnership activities in the oil and gas industry as well as activities related to emerging unconventional resources. Educational programs and training facilities were described. The employment and procurement practices of leading oil and gas operators were discussed. The supplement featured presentations by several leading oil and gas companies. tabs., figs.

Interest grows in African oil and gas opportunities

International Nuclear Information System (INIS)

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

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

The economics of Australia's oil and gas industry

International Nuclear Information System (INIS)

McDonald, Rob

1994-01-01

This article evaluates the performance of the Australian oil and gas industry, focusing on the listed companies. A large part of the Australian oil and gas industry-(as much as 60 per cent)-is held by unlisted companies or by major international groups not listed in Australia. Nevertheless, it was considered that the sample of companies reviewed gives a reasonable guide to overall industry performance. Also, as part of this relative analysis, the Australian oil and gas industry will be compared to other investments that shareholders could have enjoyed. As well, its performance will be compared with the much larger industry in the United States. It is shown that over the past 10 to 20 years, the rate of return that the Australian oil and gas industry has offered to providers of equity capital has been less than industry expectations. While it was a better performer than the smaller US companies, it lagged substantially behind the major three sectors of the US index, which are international integrated gas distribution and domestic. 10 figs

Oil and Gas Emergency Policy: Japan 2013 update

Energy Technology Data Exchange (ETDEWEB)

NONE

2013-06-01

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

US crude oil, natural gas, and natural gas liquids reserves: 1990 annual report

International Nuclear Information System (INIS)

1991-09-01

The primary focus of this report is to provide an accurate estimate of US proved reserves of crude oil, natural gas, and natural gas liquids. These estimates were considered essential to the development, implementation, and evaluation of natural energy policy and legislation. In the past, the government and the public relied upon industry estimates of proved reserves. These estimates were prepared jointly by the American Petroleum Institute (API) and the American Gas Association (AGA) and published in their annual report, Reserves of Crude Oil, Natural Gas Liquids, and Natural Gas in the United States and Canada. However, API and AGA ceased publication of reserves estimates after their 1979 report. By the mid-1970's, various federal agencies had separately established programs to collect data on, verify, or independently estimate domestic proved reserves of crude oil or natural gas. Each program was narrowly defined to meet the particular needs of the sponsoring agency. In response to recognized need for unified, comprehensive proved reserves estimates, Congress in 1977 required the Department of Energy to prepare such estimates. To meet this requirement, the EIA's reserves program was undertaken to establish a unified, verifiable, comprehensive, and continuing statistical series for proved reserves of crude oil and natural gas. The program was expanded to include proved reserves of natural gas liquids in the 1979 report. 36 refs., 11 figs., 16 tabs

Problems in operation of gas-oil condensate fields

Energy Technology Data Exchange (ETDEWEB)

Zheltov, Yu V; Martos, V N

1966-12-01

This is a review of various methods used to deplete gas-oil condensate reservoirs. Four depletion techniques are discussed: (1) natural depletion without injection of fluids into the reservoir; (2) depletion accompanied by gas cycling; (3) depletion in which the gas cap is separated from the oil by water injected into the reservoir, a method in which each part of the reservoir is produced essentially independently of the other; and (4) depletion in which reservoir temperature is raised above the cricondentherm point by in-situ combustion, so that gas and oil form a single phase. This method is prospective, and has not been tried in the field. Advantages and disadvantages of each method are discussed. It is concluded that a gas condensate reservoir can be depleted most economically only if some secondary energy is added. (13 refs.)

The voice of Canada's oil and natural gas industry : oil and natural gas

International Nuclear Information System (INIS)

2001-04-01

The Canadian Association of Petroleum Producers (CAPP) represents 150 members of the oil and gas industry, which together are responsible for approximately 95 per cent of the oil and natural gas produced in Canada. The upstream sector comprises companies that explore for, develop and produce petroleum resources, while the downstream sector involves companies that refine and market the resources. CAPP works closely with governments of 11 of Canada's 13 provinces and territories and with public groups to represent upstream producers active across the country. The enhancement of the economic well-being and sustainability of the upstream petroleum industry is the mission of the CAPP. The main priorities of the CAPP are: Environment, Health and Safety Stewardship, reasonable and timely access to resources, competitiveness of the Canadian industry on a global basis, the secure and efficient access to markets, and open and constructive public, government and media affairs. Some of the issues dealt with by the CAPP are sour gas, flaring, venting and industry-landowner relations, improved safety performance, federal issues such as corporate taxes and environmental issues, Aboriginal and First Nations issues, transportation costs for natural gas on major pipelines, and oil and sands bitumen issues, to name a few. The board of the CAPP is made up of 32 members. The work is carried out by hundreds of volunteers from member companies who provide their time and expertise for various committees and working groups, as well as a staff of approximately 40 people to assist them. The members provide the entire funding for CAPP, which is located in Calgary, Alberta. The document concluded with a few facts concerning the petroleum industry in general. 12 figs

On the European continent, the price of natural gas is still tied directly and to a great extent to the price of competing energies, especially heavy fuel oil and home heating oil. In other words, the gas market is linked to the oil market. Under the effect of deregulation, this model is likely to change in the future, making a shift like that which took place on the American market in the past. (author)

The objective of this study is to measure the NO 2 pollutant sorption of various trees, shrubs and ground cover plants. 32 species of trees, 64 speceis of shrubs and 13 species of ground cover plants were exposed to 3 ppm (v / v) N- 15 O 2 in a gas chamber for 60 minutes. Experiment consisted of 2 replicates. The environment conditions in the chamber were set at 30 o C, 1000 lux, and initial relative humidity 60 %. After gas treatment, plants parts were separated into leaves, stems and roots, than dried in 70 o C for 48 hours and then weighed. After weighing, those plants parts were ground to a pine powder. After kjendhal digestion, N total content of plants were analyzed by distillation method. 15 N content of plant samples were analyzed by emission spectrometer ( Yasco, N-151). The amount of N-15 absorbed by plant was the total content of 15 N in the whole plants ( leaves, stem and root ) per gram dry weight of leaves. The amount of 15 N absorbed by plants varied among investigated plants. 15 N sorption of trees are in the range 0.28 - 68.31μg/g. The sorption of shrubs and ground cover plants varied in 1.97 - 100.02 μg/g and 2.38 - 24.06μg/g, respectively. According to the amount of 15 N sorption , the plants were divided into 3 groups of sorption level, high ( > 30.0μg/g), moderate ( 15 - 30 μg/g ), and low sorption level ( 15 μg/g). Results showed that among of 32 investigated trees, 64 shrubs and 13 ground cover plant, 4 species of trees and 13 species of shrubs performed a high sorption level and no one of ground cover plants performed a high sorption level. The species of trees and 15 species of shrubs that mention above are recommended to use as an element of landscape which to be functioned to reduce NO 2 atmospheric pollutant

Oil and gas competition in Western Europe

International Nuclear Information System (INIS)

Carrie, J.L.

1991-01-01

This paper reports that in Western Europe, the competition between oil and gas began on a large scale during the 1960s. Indeed, natural gas accounted for only 2 percent of Western Europe's energy consumption in 1960 and for already 7 percent in 1970. It now accounts for about 17 percent. Almost all of this increase took place at the detriment of oil products. The competition between those two energy sources has resulted in the development of natural gas supply on one hand, and in several political and economic factors on the other

Separated influence of crude oil prices on regional natural gas import prices

International Nuclear Information System (INIS)

Ji, Qiang; Geng, Jiang-Bo; Fan, Ying

2014-01-01

This paper analyses the impact of global economic activity and international crude oil prices on natural gas import prices in three major natural gas markets using the panel cointegration model. It also investigates the shock impacts of the volatility and the increase and decrease of oil prices on regional natural gas import prices. The results show that both global economic activity and international crude oil prices have significant long-term positive effects on regional natural gas import prices. The volatility of international crude oil prices has a negative impact on regional natural gas import prices. The shock impact is weak in North America, lags in Europe and is most significant in Asia, which is mainly determined by different regional policies for price formation. In addition, the response of natural gas import prices to increases and decreases in international crude oil prices shows an asymmetrical mechanism, of which the decrease impact is relatively stronger. - Highlights: • Impacts of world economy and oil prices on regional natural gas prices are analysed • North American natural gas prices are mainly affected by world economy • Asian and European natural gas prices are mainly affected by oil prices • The volatility of oil prices has a negative impact on regional natural gas prices • The response of natural gas import prices to oil prices up and down shows asymmetry

A comparison of contributions from these three sources using a list of positive and negative words from the General Inquirer Category Listings showed that industry provided a very positive message about the production and consumption of oil and gas that is generally reinforced by government whereas NGOs advocated for a reduction in the use of oil and gas. Messages delivered by each player are focused on the same topics in either a positive or negative way and are often contradictory. The authors submit to be properly informed the public must consider all the sources in order to avoid bias. A mind map is presented in a supplementary file which summarizes information from each source in a comprehensive way. This approach can be used by consumers when considering the choice of using oil and gas and can be extended to the discourse beyond Canada.

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.

The unpredictability of estimating reserves of oil and gas has made it imperative to develop a universal set of definitions and guidelines for calculating and classifying reserves. A committee of representatives from the oil and gas industry, consulting firms, industry associations, regulatory agencies, government, and financial organizations in Canada has prepared definitions of oil and gas resources and reserves, as well as a recommended classification system for those reserves. The committee believes these definitions and guidelines are suitable for use with respect to all types of oil and gas and related substances, including offshore situations and oil sands. Both deterministic and probabilistic methods are presented, as well as guidelines for specific methods including the volumetric, material balance, decline curve analysis, and reservoir simulation methods. The guidelines also consider reserves from improved recovery projects and reserves of natural gas liquids and sulfur. A glossary of terms is appended. 14 figs.

processes. These models were built on a numerical framework for solving conservation law problems in one-dimensional geometries such as spheres, cylinders, and lines. Coupled with the framework are specific models for adsorption in commercial adsorbents, such as zeolites and mordenites. Utilizing this modeling approach, the authors were able to accurately describe and predict adsorption kinetic data obtained from experiments at a variety of different temperatures and gas phase concentrations. A demonstration of how these models, and framework, can be used to simulate adsorption in fixed- bed columns is provided. The CO₂ absorption work involved modeling with supportive experimental information. A dynamic model was developed to simulate CO₂ absorption using high alkaline content water solutions. The model is based upon transient mass and energy balances for chemical species commonly present in CO₂ absorption. A computer code was developed to implement CO₂ absorption with a chemical reaction model. Experiments were conducted in a laboratory scale column to determine the model parameters. The influence of geometric parameters and operating variables on CO₂ absorption was studied over a wide range of conditions. Continuing work could employ the model to control column operation and predict the absorption behavior under various input conditions and other prescribed experimental perturbations. The value of the validated models and numerical frameworks developed in this project is that they can be used to predict the sorption behavior of off-gas evolved during the reprocessing of nuclear waste and thus reduce the cost of the experiments. They can also be used to design sorption processes based on concentration limits and flow-rates determined at the plant level.

The understanding of the fluid flow in porous media requires the knowledge of the pore system involved. Fluid flow in fine grained shales falls under different regime than transport regime in conventional reservoir due to the different average pore sizes in the two materials; the average pore diameter of conventional sandstones is on the micrometer scale, while of shales can be as small as several nanometers. Mercury intrusion porosimetry is normally used to characterize the pores of conventional reservoir, however with increasingly small pores, the injection pressure required to imbibe the pores becomes infinitely large due to surface tension. Characterization of pores can be expressed by a pore size distribution (PSD) plot, which reflects distribution of pore volume or surface area with respect to pore size. For the case of nanoporous materials, the surface area, which serves as the interface between the rock matrix and fluid, becomes increasingly large and important. Physisorption of gas has been extensively studied as a method of nanoporous solid characterization (particularly for the application of catalysis, metal organic frameworks, etc). The PSD is obtained by matching the experimental result to the calculated theoretical result (using Density Functional Theory (DFT), a quantum mechanics based modelling method for molecular scale interactions). We present the challenges and experimental result of Nitrogen and CO2 gas sorption on shales with various mineralogy and the interpreted PSD obtained by DFT method. Our result shows significant surface area contributed by the nanopores of shales, hence the importance of surface area measurements for the characterization of shales.

Modelling a deep water oil/gas spill under conditions of gas hydrate formation and decomposition

International Nuclear Information System (INIS)

Zheng, L.; Yapa, P.D.

2000-01-01

A model for the behavior of oil and gas spills at deepwater locations was presented. Such spills are subjected to pressures and temperatures that can convert gases to gas hydrates which are lighter than water. Knowing the state of gases as they rise with the plume is important in predicting the fate of an oil or gas plume released in deepwater. The objective of this paper was to develop a comprehensive jet/plume model which includes computational modules that simulate the gas hydrate formation/decomposition of gas bubbles. This newly developed model is based on the kinetics of hydrate formation and decomposition coupled with mass and heat transfer phenomena. The numerical model was successfully tested using results of experimental data from the Gulf of Mexico. Hydrate formation and decomposition are integrated with an earlier model by Yapa and Zheng for underwater oil or gas jets and plumes. The effects of hydrate on the behavior of an oil or gas plume was simulated to demonstrate the models capabilities. The model results indicate that in addition to thermodynamics, the kinetics of hydrate formation/decomposition should be considered when studying the behavior of oil and gas spills. It was shown that plume behavior changes significantly depending on whether or not the local conditions force the gases to form hydrates. 25 refs., 4 tabs., 12 figs

Full Text Available Gas Production Generated from Crude Oil Biodegradation: Preliminary Study on its Aplication in MicrobialEnhanced Oil Recovery (MEOR. The objective of this study is to observe the capacity of gas production generatedfrom crude oil degradation by the isolated bacteria. The gas in the MEOR could increase pressure in the reservoir,decrease oil viscosity, increase oil permeability-due to the increase of the porosity and viscosity, and also increase oilvolume due to the amount of dissolved gas. A research on gas analysis of oil degradation by 6 isolated bacteria has beenconducted. The bacteria isolates including Bacillus badius (A, Bacillus circulans (B, Bacillus coagulans (C, Bacillusfirmus (D, Pasteurella avium (E and Streptobacillus moniliformis (F. The trial on gas production, gas analysis and oildegradation analysis, was carried out by using SMSS medium. The test of gas production was done by usingmicrorespirometer at 40°C. The result shows that B, C, D, E produce more gas than A and F. Gas of CO2, O2, CO, N2,CH4, and H2 were analyzed by using GC. The results show that only three gases were detected by GC i.e. CO2, N2, andO2. The concentration of CO2 and N2 gas increased while the concentration of O2 decreased over an 8th day ofobservation. CO2 gas producted by mix culture was higher than by the pure culture. On the 8th day of incubation, theproduction of CO2 gas by mix culture was 4,0452% while pure culture C and D only produced 2,4543% and 2,8729%.The mix culture increase simple hydrocarbon by 12.03% and the formation of a complex hydrocarbon by 3.07%. Themix culture (C-D generated the highest concentration of CO2 gas as well as a synergistic concortium that has ability todegrade crude oil.

Oil and Gas Emergency Policy: Sweden 2012 update

Energy Technology Data Exchange (ETDEWEB)

NONE

2012-07-01

Oil and natural gas represented respectively 27% and 3% of Sweden’s total primary energy supply (TPES) in 2010. With coal representing 5% of TPES, Sweden has the lowest share of fossil fuels in the energy supply mix among IEA member countries. This is a significant difference from the mid-1970s, when fossil fuels made up three-quarters of Sweden’s energy supply, and is the result of a concerted effort to move away from the use of oil through the development of nuclear and renewable energy sources. Sweden’s energy policy seeks to further increase the share of renewable energy sources, including having them provide half of all energy, and 10% of all transport needs, by 2020. The share of fossil fuel is also to be further reduced, through plans to fully eliminate their use for heating purposes by 2020 and having a vehicle stock in Sweden that is ''independent'' of fossil fuels by 2030. Under this policy, demand for both oil and natural gas is anticipated to decline from current levels. Oil demand in Sweden was nearly 330 thousand barrels per day (kb/d) in 2011. While fully dependent on imports to meet domestic oil demand, Sweden is a net exporter of refined oil products. Overall oil demand will likely decline in the coming decade, however demand for oil in the transport sector is expected to grow. At the same time, oil demand will be ever more concentrated on transport diesel, with demand for the fuel reaching over 110 kb/d by 2020 compared to just under 80 kb/d in 2011. Concerning natural gas, consumption in Sweden totalled 1.3 billion cubic metres (bcm) in 2011, all of which was supplied via a single interconnector with Denmark. While natural gas plays only a minor role in Sweden’s TPES, its role in the energy supply of southern and western Sweden is much more substantial, accounting for around 20% of the area’s total energy use. Around 30 large consumers, including CHP plants, account for roughly 80% of total gas demand in the country

Equilibrium gas-oil ratio measurements using a microfluidic technique.

Fisher, Robert; Shah, Mohammad Khalid; Eskin, Dmitry; Schmidt, Kurt; Singh, Anil; Molla, Shahnawaz; Mostowfi, Farshid

2013-07-07

A method for measuring the equilibrium GOR (gas-oil ratio) of reservoir fluids using microfluidic technology is developed. Live crude oils (crude oil with dissolved gas) are injected into a long serpentine microchannel at reservoir pressure. The fluid forms a segmented flow as it travels through the channel. Gas and liquid phases are produced from the exit port of the channel that is maintained at atmospheric conditions. The process is analogous to the production of crude oil from a formation. By using compositional analysis and thermodynamic principles of hydrocarbon fluids, we show excellent equilibrium between the produced gas and liquid phases is achieved. The GOR of a reservoir fluid is a key parameter in determining the equation of state of a crude oil. Equations of state that are commonly used in petroleum engineering and reservoir simulations describe the phase behaviour of a fluid at equilibrium state. Therefore, to accurately determine the coefficients of an equation of state, the produced gas and liquid phases have to be as close to the thermodynamic equilibrium as possible. In the examples presented here, the GORs measured with the microfluidic technique agreed with GOR values obtained from conventional methods. Furthermore, when compared to conventional methods, the microfluidic technique was simpler to perform, required less equipment, and yielded better repeatability.

Britain's North Sea oil and gas production: a critical review

International Nuclear Information System (INIS)

Odell, P.R.

1996-01-01

The size and longevity of Britain's offshore hydrocarbons resources have been underestimated. Gas reserves were seriously under-exploited for almost 20 years from the late 1960s, given a belief that gas should be used only as a premium fuel and in the context of an uncompetitive market. Oil reserves' development and production has suffered from time to time from inappropriate politico-economic conditions. Nevertheless, offshore oil and gas has come to dominate the UK's energy production over the past 20 years and currently accounts for 85% of the country's total energy output. Fears for resources' exhaustion remain unjustified, as the industry continues to replace oil and gas reserves used each year. The North Sea is still not comprehensively explored: the continuation of the process will enable oil production to remain at high levels and that of gas to expand further. Supplementary output from the new west of Shetland province will become progressively more important after 2000. But continued intensive production overall depends on the maintenance of attractive politico-economic conditions and on present oil prices. It also requires the European gas market to remain firm but, ironically, the planned flow of UK gas to the mainland constitutes a threat to this condition. (Author)

2003-01-01

An update of the Canadian petroleum and natural gas industry was presented with reference to activity trends and major issues. The presentation also described opportunities and challenges facing the industry in British Columbia and reviewed the impact of federal policies on BC. In recent years the industry has moved to oil sands and unconventional gas, offshore sites, and coalbed methane development. Other changes are a result of technology which makes it possible to drill deeper and faster while having less environmental impact. Government issues have become increasingly complex, however. Industry capital spending from 2000 to 2003 was presented for Northern Canada, the east coast offshore, Alberta, the Western Canada Sedimentary Basin, oil sand deposits, and international activities. The presentation included several graphs depicting: the changing natural gas production mix; North American natural gas demand; wells drilled by province; natural gas resources in BC; upstream capital spending in BC; wells drilled by type and depth in BC; top natural gas wells in 2000 and 2002; natural gas production in BC; finding and development costs for Canadian natural gas; and, the widening gap of the federal income tax rate between oil and natural gas and other industries. British Columbia is in the strategic position of having significant untapped gas potential in the northeastern part of the province. For now, there is sufficient pipeline capacity to bring the gas to markets in the United States where there is a strong demand for electric power generation. 16 figs

The hydrocracking of synthetic crude gas oils (SGO), which are commercially produced from Canadian oil sands, is strongly inhibited by nitrogen-containing species. To alleviate the pronounced effect of these nitrogenous compounds, SGO was hydrotreated at severe conditions prior to hydrocracking to reduce its N content from 1665 to about 390 ppm (by weight). Hydrocracking was then performed using a commercial nickel-tungsten catalyst supported on silica-alumina. Two-stage hydroprocessing of SGO was assessed in terms of product yields and quality. As expected, higher gas oil conversion were achieved mostly from an increase in naphtha yield. The middle distillate product quality was also clearly improved as the diesel fuel cetane number increased by 13%. Diesel engine tests indicated that particulate emissions in exhaust gases were lowered by 20%. Finally, pseudo first-order kinetic equations were derived for the overall conversion of the major gas oil components. 17 refs., 2 figs., 8 tabs.

Noble gases are powerful tracers of fluids from various oil and gas production activities in hydrocarbon reservoirs and nearby groundwater. Non-radiogenic noble gases are introduced into undisturbed oil and natural gas reservoirs through exchange with formation waters [1-3]. Reservoirs with extensive hydraulic fracturing, injection for enhanced oil recovery (EOR), and/or waste disposal also show evidence for a component of noble gases introduced from air [4]. Isotopic and elemental ratios of noble gases can be used to 1) assess the migration history of the injected and formation fluids, and 2) determine the extent of exchange between multiphase fluids in different reservoirs. We present noble gas isotope and abundance data from casing, separator and injectate gases of the Lost Hills and Fruitvale oil fields in the San Joaquin basin, California. Samples were collected as part of the California State Water Resource Control Board's Oil and Gas Regional Groundwater Monitoring Program. Lost Hills (n=7) and Fruitvale (n=2) gases are geochemically distinct and duplicate samples are highly reproducible. Lost Hills casing gas samples were collected from areas where EOR and hydraulic fracturing has occurred in the past several years, and from areas where EOR is absent. The Fruitvale samples were collected from a re-injection port. All samples are radiogenic in their He isotopes, typical of a crustal environment, and show enrichments in heavy noble gases, resulting from preferential adsorption on sediments. Fruitvale samples reflect air-like surface conditions, with higher air-derived noble gas concentrations. Lost Hills gases show a gradation from pristine crustal signatures - indicative of closed-system exchange with formation fluids - to strongly air-contaminated signatures in the EOR region. Pristine samples can be used to determine the extent of hydrocarbon exchange with fluids, whereas samples with excess air can be used to quantify the extent of EOR. Determining noble

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

Future Oil and Gas Resources of the World: A Coming Supply Crisis?

Science.gov (United States)

Ahlbrandt, T. S.

2002-05-01

Is the world running out of oil? Where will future oil and gas supplies come from? To help answer these questions, the U.S. Geological Survey completed in 2000 a new assessment of the undiscovered conventional oil and gas resources and potential additions to reserves from field growth. One hundred and twenty-eight provinces were assessed in a 100 man-year effort from 1995-2000. The assessed provinces included 76 priority provinces containing 95 percent of the world's discovered oil and gas and an additional 52 "boutique" provinces, many of which may be highly prospective. Total Petroleum Systems (TPS) were identified and described for each of these provinces along with associated Assessment Units (AU) that are the basic units for assessing undiscovered petroleum. The assessment process coupled geologic analysis with a probabilistic methodology to estimate remaining potential. Within the 128 assessed provinces, were 159 TPS and 274 AU. For these provinces, the endowment of recoverable oil, which includes cumulative production, remaining reserves, reserve growth, and undiscovered resources is estimated at about 3 trillion barrels of oil (TBO). The natural gas endowment is estimated at 2.6 trillion barrels of oil equivalent (TBOE). Oil reserves are currently 1.1 TBO; world consumption is about .028 TBO per year. Natural gas reserves are about .8 TBOE; world consumption is about .014 TBOE. Thus, without any additional discoveries of oil, gas or natural gas liquids, we have about 2 TBOE of proved petroleum reserves. Of the oil and gas endowment of about 5.6 TBOE, we estimate that the world has consumed about 1 TBOE, or 18 percent leaving about 82 percent of endowment to be utilized or found. Half of the world's undiscovered potential is offshore. Arctic basins with about 25 percent of undiscovered petroleum resources make up the next great frontier. An additional 279 provinces contain some oil and gas and, if considered, would increase the oil and gas endowment

America's gas tank : the high cost of Canada's oil and gas export strategy

International Nuclear Information System (INIS)

Price, M.; Bennett, J.

2002-10-01

The high environmental cost of exporting oil and gas from Canada to the United States is discussed. The increased demand for fossil fuels by the United States has coincided with Canada's deregulation of the energy industry and a greater control of Canadian energy companies by American interests. The authors note that most of the oil and gas produced in Canada is exported to the United States, where many of the extraction and production decisions affecting Canadians and the Canadian environment are made. It was cautioned that if the current trend continues, oil and gas development will degrade habitat for endangered species and greenhouse gases will escalate. This is because the fossil fuel industry, particularly the development of Alberta's tar sands, is helping to increase greenhouse gas emissions outside of Canada by selling fossil fuels that are burned outside of Canada. It is recommended that federal and provincial governments in Canada should shift their policies away from fossil fuel production and promote renewable energy production. The United States plans to increase Canadian oil and gas imports in the coming decade, requiring more wells to be drilled and pipelines to carry it. If the fossil fuel industry proceeds with the current plans, greenhouse gas emissions in Canada will grow to 827 million tonnes by 2010, 44 per cent beyond the Kyoto target, having an overall negative impact on public health, wildlife and fresh water supplies. refs., tabs., figs

One of the major problems related to the use of oil base fluids is the dissolution of the natural gas in the fluid. This paper attempts initially at making a bibliographical review of all that was written on the subject of drilling fluids up to now. It also mentions some theoretical aspects regarding the process of gas dissolution in diesel oils, in order to produce an understanding of how the dissolution mechanism is processed. For a same increase in measured volume on the surface, the amount of gas incorporated into the fluid is significantly larger if the gas is dissolved in the oil phase than if it is emulsified in the fluid, as occurs when the fluid is water base. A rig team used to working with water-base fluids may be surprised with the fact that an increase of 20 bbl of fluid on the surface of a 5000 m well can mean the incorporation of about 1800 m{sup 3} of gas, if the fluid is oil-base and all the gas is in solution instead of the incorporation of 900 m{sup 3} if the fluid is water base. This paper has the goal of warning drilling engineers and technicians about this problem, as well as presenting charts and equations that allow for a more realistic evaluation of the amount of gas incorporated into oil fluids.

Understanding gas sorption by water in the atmosphere is an active research area because the gases can significantly alter the radiation and chemical properties of the atmosphere. We attempt to elucidate the molecular details of the gas sorption of water and three common atmospheric gases (N2O5, SO2, and O3) by water droplets/slabs in molecular dynamics simulations. The system size effects are investigated, and we show that the calculated solvation free energy decreases linearly as a function of the reciprocal of the number of water molecules from 1/215 to 1/1000 in both the slab and the droplet systems. By analyzing the infinitely large system size limit by extrapolation, we find that all our droplet results are more accurate than the slab results when compared to the experimental values. We also show how the choice of restraints in umbrella sampling can affect the sampling efficiency for the droplet systems. The free energy changes were decomposed into the energetic ΔU and entropic -TΔS contributions to reveal the molecular details of the gas sorption processes. By further decomposing ΔU into Lennard-Jones and Coulombic interactions, we observe that the ΔU trends are primarily determined by local effects due to the size of the gas molecule, charge distribution, and solvation structure around the gas molecule. Moreover, we find that there is a strong correlation between the change in the entropic contribution and the mean residence time of water, which is spatially nonlocal and related to the mobility of water.

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

Roberge, R.B.

1997-01-01

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

Environmental requirements for oil and gas operations in Saskatchewan

International Nuclear Information System (INIS)

Nystuen, L.J.

1997-01-01

The administration and regulation of environmental issues regarding the oil and gas industry in Saskatchewan were discussed. The political and cultural differences in Saskatchewan that make environmental processes distinct from its neighbouring jurisdictions were described. The following Saskatchewan legislation deals with environmental requirements: Environmental Management and Protection Act, Environmental Assessment Act, Oil and Gas Conservation Act, Wildlife Habitat Protection Act, Clean Air Act, Planning and Development Act, Forest Act, Water Corporation Act, Heritage Property Act, and Parks Act. The Saskatchewan Department of Energy and Mines (SEM) is the primary regulator of the upstream oil and gas industry. It regulates the construction, operation, reporting and abandonment requirements for oilfield operations. SEM also manages crude oil prior to refining and manages the wastes contaminated with crude oil. Provisions of the relevant Acts regarding drilling in environmentally sensitive areas, flaring requirements, transporting and disposing of oilfield wastes, road-building, operating restrictions, emergency response plans, spill clean-up responsibilities, well abandonment and site reclamation responsibilities were discussed. 8 refs., 2 tabs

Speciation of trialkylated arsenic compunds in natural gas, pressurized and stable condensate samples from the same gas well was performed using (Cryotrapping) Gas Chromatography-Inductively Coupled Plasma Mass Spectrometry. The major species in all phases investigated was found to be trimethylarsine with a highest concentration of 17.8 ng/L (As) in the gas phase and 33.2 μg/L (As) in the stable condensate phase. The highest amount of trimethylarsine (121 μg/L (As)) was found in the pressurized condensate, along with trace amounts of non-identified higher alkylated arsines. Volatile arsenic species in natural gas and its related products cause concern with regards to environment, safety, occupational health and gas processing. Therefore, interest lies in a fast and simple field method for the determination of volatile arsenicals. Here, we use simple liquid and solid sorption techniques, namely absorption in silver nitrate solution and adsorption on silver nitrate impregnated silica gel tubes followed by total arsenic determination as a promising tool for field monitoring of volatile arsenicals in natural gas and gas condensates. Preliminary results obtained for the sorption-based methods show that around 70% of the arsenic is determined with these methods in comparison to volatile arsenic determination using GC-ICP-MS. Furthermore, an inter-laboratory- and inter-method comparison was performed using silver nitrate impregnated silica tubes on 14 different gas samples with concentrations varying from below 1 to 1000 μg As/m 3 natural gas. The results obtained from the two laboratories differ in a range of 10 to 60%, but agree within the order of magnitude, which is satisfactory for our purposes

Plastics - the sustainable way to use Oil and Gas

Energy Technology Data Exchange (ETDEWEB)

Siebourg, Wolfgang

2009-07-01

Conclusions (drawn by the author): Plastics are a sustainable use of oil and gas - Plastic products enable significant savings of energy and GHG emissions particularly in the use phase; - Plastic products help use resources in the most efficient way. Restricting plastics relative growth would result in increased energy consumption. Diversion from landfill would increase resource efficiency. Waste-to-Energy is an additional resource and is complementary to mechanical recycling. Plastics producers and the Oil and Gas industry should cooperate to produce reliable consumption data. Oil and Gas industry should develop and maintain European (world) eco-profiles (cradle to gate) for their respective industry. (author)

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.

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.

Emsile, B.H.

1998-01-01

The current regulations regarding disclosure of oil and gas reserve information in Canada are described. These regulations have been in place since the early 1980s and have generally worked well, but there are some issues that need to be updated. The Alberta Securities Commission Oil and Gas Securities Task Force was established to review the regulations and the major issues that need to be addressed. The issues under consideration are: (1) reserve definitions and price assumptions, (2) use of deterministic or probabilistic reserve calculation methods, (3) use of audits in reserve reporting, (4) abandonment costs, (5) calculation of barrels of oil equivalents, and (6) the calculation of various performance indicators such as finding and development costs and reserve replacement ratios

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.

Coated kapok fiber for removal of spilled oil

International Nuclear Information System (INIS)

Wang, Jintao; Zheng, Yian; Wang, Aiqin

2013-01-01

Highlights: ► A low-cost and biodegradable oil absorbent based on kapok fiber was prepared. ► The polymer-coated kapok fiber showed higher oil sorption capacity. ► Coated kapok fiber can be reused and the absorbed oil can be easily recovered. ► Adsorption of oil is spontaneous and exothermic physisorption and chemisorption. -- Abstract: Based on raw kapok fiber, two kinds of oil absorbers with high sorption capacity were prepared by a facile solution–immersion process. The coated polymer with low surface energy and rough fiber surface play important role in the retention of oil. The as-prepared fiber can quickly absorb gasoline, diesel, soybean oil, and paraffin oil up to above 74.5%, 66.8%, 64.4% and 47.8% of oil sorption capacity of raw fiber, respectively. The absorbed oils can be easily recovered by a simple vacuum filtration and the recovered coated-fiber still can be used for several cycles without obvious loss in oil sorption capacity. The thermodynamic study indicates that the adsorption process is spontaneous and exothermic, with complex physisorption and chemisorption. The results suggest that the coated fiber can be used as a low-cost alternative for the removal of oil spilled on water surface

Application of local singularity in prospecting potential oil/gas Targets

Directory of Open Access Journals (Sweden)

Zhengyu Bao

2007-06-01

Full Text Available Together with generalized self-similarity and the fractal spectrum, local singularity analysis has been introduced as one part of the new 3S principle and technique for mineral resource assessment based on multifractal modeling, which has been demonstrated to be useful for anomaly delineation. Local singularity is used in this paper to characterize the property of multifractal distribution patterns of geochemical indexes to delineate potential areas for oil/gas exploration using the advanced GeoDAS GIS technology. Geochemical data of four oil/gas indexes, consisting of acid-extracted methane (SC1, ethane (SC2, propane (SC3, and secondary carbonate (ΔC, from 9637 soil samples amassed within a large area of 11.2×104 km2 in the Songpan-Aba district, Sichuan Province, southwestern China, were analyzed. By eliminating the interference of geochemical oil/gas data with the method of media-modification and Kriging, the prospecting area defined by the local singularity model is better identified and the results show that the subareas with higher singularity exponents for the four oil/gas indexes are potential targets for oil/gas exploration. These areas in the shape of rings or half-rings are spatially associated with the location of the known producing drilling well in this area. The spatial relationship between the anomalies delineated by oil/gas geochemical data and distribution patterns of local singularity exponents is confirmed by using the stable isotope of δ13C.

State sells oil and gas shares in Norway - Statoil to stock exchange list

International Nuclear Information System (INIS)

Kimpanpaeae, M.

2001-01-01

After several months debate the government of Norway has decided to sell parts of the national oil-company Staoil as well as state-owned gas and oil shares. The government has stated that in the first stage it would be possible to privatize 20% of the Statoil. The market value of Staoil in summer 1999 was estimated to 120 billion NOK and the value has been estimated to increase ever since. The same proposal includes selling 20% of the national oil and gas shares SDOEE. 15 % would be sold to Statoil before listing the company into the stock exchange and the rest to Norsk Hydro and other national and international companies. The remaining share, the value of which is about 500 billion NOK, will become a part of a new state-owned company. The oil and energy ministry of Norway has estimated that the market value of SDOEE is about 600 billion NOK. Advisory committee decided to increase the share to be sold of SDOEE to 21.5%, the share of other companies being 6.5%. SDOEE was grounded in 1985. Since then a part of the oil and gas income of Statoil has gone into the balances of Statoil and another part directly to the state. Statoil has been responsible for the oil and gas sales of SDOEE. SDOEE's gas and oil reserves have been estimated to be about 9.8 billion barrels, 35% of which is oil and the rest natural gas. A new independent state owned company will be founded for transport of natural gas as a part of the change process. Oil companies and other energy companies will deliver the natural gas also in the future. In addition to the national arrangements, the EU's gas market directive will lead to changes in the Norwegian gas sales. As a part of the European Economic Area Norway will put the EU's gas markets directive into force without any transition period. The directive will decrease the price of natural gas and hence the income of Norway from natural gas is estimated to decrease significantly. At the moment the sales company GFU is responsible for organizing the

Riqueros, N. S.; Kang, M.; Jackson, R. B.

2015-12-01

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.

Oil and gas financing by the World Bank

International Nuclear Information System (INIS)

Razavi, Hossein

1995-01-01

The World Bank has developed a flexible oil and gas programme that is structured to meet the changing needs of the sector as they arise. The Bank became prominent in the oil and gas sector after the oil crises of the 1970s, when it began assisting client countries in developing their indigenous energy resources. At the beginning, Bank lending concentrated on exploration and development of hydrocarbon resources where the level of lending expanded to US$1 billion in 1983. This rapid expansion caused some concern that Bank activities might preempt those of the private sector. In response, the Bank imposed in 1984 strict limitations on petroleum exploration and oil production lending. In combination with the perception that future oil demand would be weak, this caused the lending programme to fall off sharply (to US$300 million by 1986). By 1990, the Bank was again moving actively into hydrocarbon sector lending, but then the emphasis was on promoting private sector development and supporting the development of natural gas as a substitute for coal and oil. Bank lending to the sector has been on the increase since 1990; a lending level of about US$1 billion yearly is expected for the second half of the 1990s. In addition to its direct lending, the World Bank facilitates contributions by other financiers through its cofinancing and risk mitigation arrangements. (author)

Asian gas and oil supplies, production, and utilization

International Nuclear Information System (INIS)

Jonchere, J.P.

1991-01-01

Some changes which have occurred recently, or which are now emerging, allow one to consider commercial energy revolving effectively around three poles--oil, natural gas and electricity, and these to be viewed more and more as commodities for services. A hard core of oil consumption, mainly dedicated to the transportation sector, will continue to fuel the crude oil demand growth. In Asia, such a trend will lead to an increasing reliance on Middle East crudes and thus to the need to upgrade the heavier part of the barrel. For its part, natural gas will help to limit the reliance on oil, and its resource base is large enough to offer it increasing shares in two key energy consuming sectors: electricity generation and nitrogen fertilizers. Moreover, concerns about the need to conserve natural gas reserves for use as a feedstock for nitrogen fertilizers and other petrochemicals, do not affect the picture. Limited amounts would be required and a dynamic approach to the development of fossil fuel resources enables the consideration of natural gas as a transitional fuel for the energy hungry power sector. However, in the meantime it is expected to play a key role both in safeguarding the environment and alleviating the investment burden, particularly in the power and nitrogen fertilizer sectors

Kinetics of Cd2+ and Cr3+ Sorption from Aqueous Solutions Using Mercaptoacetic Acid Modified and Unmodified Oil Palm Fruit Fibre(Elaeis guineensis) Adsorbents

Institute of Scientific and Technical Information of China (English)

无

2007-01-01

The kinetics of the sorption of Cd2+ and Cr3+ from aqueous solutions by mercaptoacetic acid modified and unmodified oil palm fruit fibre adsorbents were investigated. The results indicate that sorption equilibrium was reached within 60 min for both metals. Also, the removal efficiency of the three adsorbents was observed to increase for both metals with stronger treatments with mercaptoacetic acid. This may be attributed to the influence of the thiolation of the adsorbents. Furthermore, Cr3+ had higher removal percentages than Cd2+ for all the adsorbents. The sorption mechanism based on the intraparticle diffusion model shows that Cd2+ sorption is better described than Cr3+. The intraparticle diffusion rate constants, K1d, for Cd2+are 62.04 min-1 (untreated), 67.01 min-1 (treated with 0.5 mol/L mercaptoacetic acid), and 71.43 min-1(treated with 1.0 mol/L mercaptocacetic acid) while those for Cr3+ are 63.41 min-1 (untreated), 65.79 min-1(0.5 mol/L acid treated), and 66.25 min-1 (1.0 mol/L acid treated).

Combilift ideal for maneuvering oil and gas equipment

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.

2017-07-01

Shale gas has become a new sweet spot of global oil and gas exploration, and the large amount of flowback water produced during shale gas extraction is attracting increased attention. Internal recycling of flowback water for future hydraulic fracturing is currently the most effective, and it is necessary to decrease the content of divalent cations for eliminating scaling and maintaining effectiveness of friction reducer. Zeolite has been widely used as a sorbent to remove cations from wastewater. This work was carried out to investigate the effects of zeolite type, zeolite form, activation chemical, activation condition, and sorption condition on removal of Ca 2+ and Mg 2+ from shale gas flowback water. Results showed that low removal of Ca 2+ and Mg 2+ was found for raw zeolite 4A and zeolite 13X, and the efficiency of the mixture of both zeolites was slightly higher. Compared with the raw zeolites, the zeolites after activation using NaOH and NaCl greatly improved the sorption performance, and there was no significant difference between dynamic activation and static activation. Dynamic sorption outperformed static sorption, the difference exceeding 40% and 7-70% for removal of Ca 2+ and Mg 2+ , respectively. Moreover, powdered zeolites outperformed granulated zeolites in divalent cation removal.

An overview of Saskatchewan legislative framework regarding the oil and gas industry was presented. In the oil and gas industry, environmental issues are regulated at the provincial level, but the industry must also be aware of federal environmental law when dealing with federal lands, federal financial assistance, interprovincial or international projects or projects which have transboundary environmental effects. In this context, the provisions of the Oil and Gas Conservation Act (OGCA) and the Oil and Gas Conservation Regulations (OGCR), the licensing of oil and gas wells, the acquisition and surrender of surface rights, and the procedures involved in environmental assessment approval were outlined. Emission control, air pollution abatement, the storage and disposal of hazardous materials, environmental issues in property transactions, and corporate environmental management are also subject to regulation under OGCA and OGCR. 42 refs

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

Oil and gas trends and implications in Malaysia

Rahim, Khalid Abdul; Liwan, Audrey

2012-01-01

The trends of reserves, production and consumption of oil in Malaysia to meet the ever-increasing demands do not seem to show that oil and gas will be depleted soon, contrary to many reports. Malaysia’s net exporter status of oil continues to expand over time for as long as the value of exports is greater than the value of imports. Only in physical quantities of oil that Malaysia’s imports exceed exports, but this does not mean that Malaysia will be a net importer by then. Given higher prices of exports, the value of exports outweighs the value of imports. If the current reserves are extracted based on the domestic consumption trend of 1980–2010, Malaysia’s reserves will last until 2027 but based on the 1998–2010 trend, the reserves will be depleted by 2035. Malaysia has adopted a four fuel diversification strategy comprising oil, gas, coal and hydro, instead of heavily dependent on oil. Gas has a huge potential for domestic utilization as well as for exports to increase revenues. Malaysia is one of the few countries having many types of renewable energy sources. Malaysia has great potential in biomass utilization as renewable resources mostly from the existing natural forest and planned plantations. - Highlights: ► The quantities of petroleum production and consumption are expected to converge. ► Malaysia’s status as a net exporter in value terms is expected to expand. ► With slower consumption trend, petroleum reserves will be depleted by 2035. ► There is a large potential in natural gas utilization in Malaysia. ► Renewable energy is abundant for the fuel diversification policy for Malaysia.

2015-10-20

Recent large-scale development of oil and gas from low-permeability unconventional formations (e.g., shales, tight sands, and coal seams) has raised concern about potential environmental impacts. If left improperly sealed, legacy oil and gas wells colocated with that new development represent a potential pathway for unwanted migration of fluids (brine, drilling and stimulation fluids, oil, and gas). Uncertainty in the number, location, and abandonment state of legacy wells hinders environmental assessment of exploration and production activity. The objective of this study is to apply publicly available information on Pennsylvania oil and gas wells to better understand their potential to serve as pathways for unwanted fluid migration. This study presents a synthesis of historical reports and digital well records to provide insights into spatial and temporal trends in oil and gas development. Areas with a higher density of wells abandoned prior to the mid-20th century, when more modern well-sealing requirements took effect in Pennsylvania, and areas where conventional oil and gas production penetrated to or through intervals that may be affected by new Marcellus shale development are identified. This information may help to address questions of environmental risk related to new extraction activities.

Gas-assisted gravity drainage (GAGD) process for improved oil recovery

Science.gov (United States)

Rao, Dandina N [Baton Rouge, LA

2012-07-10

A rapid and inexpensive process for increasing the amount of hydrocarbons (e.g., oil) produced and the rate of production from subterranean hydrocarbon-bearing reservoirs by displacing oil downwards within the oil reservoir and into an oil recovery apparatus is disclosed. The process is referred to as "gas-assisted gravity drainage" and comprises the steps of placing one or more horizontal producer wells near the bottom of a payzone (i.e., rock in which oil and gas are found in exploitable quantities) of a subterranean hydrocarbon-bearing reservoir and injecting a fluid displacer (e.g., CO.sub.2) through one or more vertical wells or horizontal wells. Pre-existing vertical wells may be used to inject the fluid displacer into the reservoir. As the fluid displacer is injected into the top portion of the reservoir, it forms a gas zone, which displaces oil and water downward towards the horizontal producer well(s).

Report on the oil and gas sector in Ecuador

International Nuclear Information System (INIS)

1990-01-01

After a brief introduction on the economic and political situation in Ecuador, the state of the country's oil and gas sector is reviewed. Before 1967, all oil came from wells along the Pacific coast, but with discoveries in the Amazon Basin, the opening of the trans-Ecuador pipeline, and creation of the state oil company CEPE (renamed Petroecuador in 1990) by the early 1970s, a boom in the industry occurred. Current proven reserves stand at 1.2-1.5 billion bbl of oil and 140 billion ft 3 of natural gas. Current production is generally around 300,000 bbl/d, mostly from the Petroecuador-Texaco consortium block in the Amazon Basin. Petroecuador now operates the main oil export pipeline and has subsidiaries responsible for exploration and production, refining, and the marketing of petroleum and its derivatives. In recent years Petroecuador has imported about $60 million worth of goods annually, offering a market opportunity for foreign companies supplying goods and services to the oil and gas industry. Market opportunities of interest to Canadian companies are outlined, local procedures for doing business are presented, and lists of Canadian and Ecuadorian contacts are provided. 3 figs., 5 tabs

The U.S. Geological Survey (USGS) completed a geology-based assessment of undiscovered, technically recoverable conventional and continuous oil and gas resources in the part of the Ventura Basin Province that lies onshore or within State waters (within 3 miles of the shoreline) of California (fig. 1). Conventional oil and gas resources are those that have migrated upward into structural or stratigraphic traps from deep zones where the oil and gas is generated; water is present below the oil or gas. Continuous accumulations, in contrast, are those in which oil or gas is pervasively present in essentially all wells that penetrate them, that may not be structurally or stratigraphically trapped, and that typically lack oil-water or gas-water contacts. They are commonly produced with well-stimulation technology, such as hydraulic fracturing, referred to as “unconventional.” The same stimulation technology, however, is also used in many conventionally trapped accumulations. We estimated both the likely range of oil and gas volumes remaining to be discovered in accumulations similar to existing conventional oil and gas fields in the Ventura Basin Province (previously assessed by Keller [1995] as 1,060 million barrels of oil [MMBO], 1,900 billion cubic feet of gas [BCFG], and 60 million barrels of natural gas liquids [MMBNGL]), and the potential for oil and gas that might be present in a continuous accumulation at extreme depth in the floor of the basin.

Environmental audits of oil and gas properties

Moody, T.D.; Forbes, S.

1991-01-01

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

Development of oil and gas service as organizational form of entrepreneurship in post-industrial economy

2017-10-01

Full Text Available The article is devoted to the problem of development of oil and gas service. 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

Marketing BTUs: Gas, electricity lead oil in innovation

International Nuclear Information System (INIS)

Krapels, E.N.

1996-01-01

The transformation in relations between energy providers and users--powered by reform of electric utilities and by continuation of natural gas deregulation--is challenging several fundamental precepts of how oil companies managed their deregulation. In the wake of the price decontrol completed by the Reagan administration in 1981, oil companies (1) retreated from national business structures, (2) focused on limited range core businesses, and (3) provided minimal oil price risk management services for their customers. By contrast, the electric and natural gas industry is consolidating for the purpose of playing a role in ever-larger markets, diversifying its products and services, and providing innovative hedging instruments to itself as well as its customers. From Enron, one can purchase physical and paper energy, delivered in whatever form desired, nationwide and internationally, with or without mechanisms to manage price risk. What will impede the newly integrated energy companies--which are composite electric plus natural gas firms--from also delivering products and services now rendered by the oil companies? Could utilities organize gasoline consumers better than oil companies? If the Price Club can sell gasoline at 10 cents below market, why can't the new energy companies do so? The paper discusses what consumers want, procurement and costs, and innovations and lessons

An Investigation on Gas Lift Performance Curve in an Oil-Producing Well

Directory of Open Access Journals (Sweden)

Deni Saepudin

2007-01-01

Full Text Available The main objective in oil production system using gas lift technique is to obtain the optimum gas injection rate which yields the maximum oil production rate. Relationship between gas injection rate and oil production rate is described by a continuous gas lift performance curve (GLPC. Obtaining the optimum gas injection rate is important because excessive gas injection will reduce production rate, and also increase the operation cost. In this paper, we discuss a mathematical model for gas lift technique and the characteristics of the GLPC for a production well, for which one phase (liquid is flowing in the reservoir, and two phases (liquid and gas in the tubing. It is shown that in certain physical condition the GLPC exists and is unique. Numerical computations indicate unimodal properties of the GLPC. It is also constructed here a numerical scheme based on genetic algorithm to compute the optimum oil production.

TREATMENT OF PRODUCED OIL AND GAS WATERS WITH SURFACTANT-MODIFIED ZEOLITE

Energy Technology Data Exchange (ETDEWEB)

2003-11-01

Co-produced water from the oil and gas industry accounts for a significant waste stream in the United States. It is by some estimates the largest single waste stream in the country, aside from nonhazardous industrial wastes. Characteristics of produced water include high total dissolved solids content, dissolved organic constituents such as benzene and toluene, an oil and grease component, and chemicals added during the oil-production process. While most of the produced water is disposed via reinjection, some must be treated to remove organic constituents before the water is discharged. Current treatment options are successful in reducing the organic content; however, they cannot always meet the levels of current or proposed regulations for discharged water. Therefore, an efficient, cost-effective treatment technology is needed. Surfactant-modified zeolite (SMZ) has been used successfully to treat contaminated ground water for organic and inorganic constituents. In addition, the low cost of natural zeolites makes their use attractive in water-treatment applications. This report summarizes the work and results of this four-year project. We tested the effectiveness of surfactant-modified zeolite (SMZ) for removal of BTEX with batch and column experiments using waters with BTEX concentrations that are comparable to those of produced waters. The data from our experimental investigations showed that BTEX sorption to SMZ can be described by a linear isotherm model, and competitive effects between compounds were not significant. The SMZ can be readily regenerated using air stripping. We field-tested a prototype SMZ-based water treatment system at produced water treatment facilities and found that the SMZ successfully removes BTEX from produced waters as predicted by laboratory studies. When compared to other existing treatment technologies, the cost of the SMZ system is very competitive. Furthermore, the SMZ system is relatively compact, does not require the storage of

The time varying price spillovers between natural gas and crude oil markets for the period 1994 to 2014 are investigated. Contrary to earlier research, we show that in a large part of our sample the natural gas price leads the price of crude oil with price spillover effects lasting up to two weeks. This result is robust to a battery of tests including out-of-sample forecasting exercises. However, after 2006, we detect little price dependencies between these two energy commodities. These findings arise due to a conjunction of both demand and supply-side shocks arising from both natural and economic events, including Hurricane Katrina, the Tohoku earthquake and the Global Financial Crisis, as well as infrastructure and technological improvements. The increased use of new technologies such as hydraulic fracking for the extraction of gas and oil in particular affected supply in the latter part of the study. We conclude that the long term relation present in the early part of the sample has decoupled, such that price determination of these two energy sources is now independent. - Highlights: • Contrary to earlier research we find natural gas may lead crude oil prices over a long sample. • This finding holds in forecasting out of sample. • There may be a break in the relationship between oil and gas in 2006. • We suggest that new technologies and financial conditions have led to a decoupling of these markets. • Oil and natural gas prices may now be determined independently.

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

2001-01-01

The sorption behaviors of technetium on pyrrhotine are studied with batch experiment and dilute sulfuric acid is used to dissolve the technetium adsorbed on pyrrhotine. Sorption and desorption experiment are performed under aerobic and anaerobic conditions (inert gas box). The results show that a significant sorption of technetium on pyrrhotine is found under aerobic and anaerobic conditions, and the sorption on the mineral is supposed to be due to the reduction of TcO 4 - to insoluble TcO 2 ·nH 2 O. Desorption process of the sorbed technetium into dilute sulfuric acid is found to be different under aerobic and anaerobic conditions. On addition of H 2 O 2 to the leach solution a sudden increase of the technetium concentration is observed

Sorption of colloids, organics, and metals onto gas-water interfaces: Transport mechanisms and potential remediation technology. 1998 annual progress report

International Nuclear Information System (INIS)

Tokunaga, T.K.; Wan, J.

1998-01-01

'Although contaminant sorption at mineral surfaces has received much recognition as a major mechanism controlling contaminant behavior in subsurface environments, virtually no attention has been given to the possibility of contaminant sorption at gas-water interfaces. Moreover, no effort has yet been advanced to optimize such interactions for the purpose of facilitating in-situ remediation. Gas-water interfaces, unlike water-solid interfaces, are mobile. Therefore, associations of contaminants with gas-water interfaces can be very important not only in subsurface contaminant distributions, but also in contaminant transport, and potentially in remediation. The first objective of this research is to develop a quantitative understanding of interactions between contaminants and gas-water interfaces. The anticipated results will provide insights into the poorly understood phenomenon of contaminant interactions with the gas-water interface, and improve the current conceptual models of contaminant behavior in subsurface environments. The second purpose of this research is to explore the possibility of using surfactant stabilized microbubbles for in-situ remediation. Both pump-and-treat, and air sparging remediation methods are ineffective at displacing contaminants in zones which are advectively inaccessible. Stable microbubbles can migrate beyond preferential flow pathways and enter lower permeability zones by buoyant rise. The microbubbles can deliver oxygen and nutrients for promoting aerobic degradation of organic contaminants, and also deliver surfactants for emulsifying NAPLs.'

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

2004-01-01

This book was prepared by more than 40 contributing authors with expertise in a wide range of topics related to oil and gas reserves. It represents a collaborative effort to find definitions and guidelines for the classification of reserves that is acceptable to the oil industry, evaluators, oil and gas companies, financial agencies, securities commissions and government departments. This second edition is an update of the original work that was published in 1994 which compares estimates of reserves and their classification. The new edition includes changes that have occurred in the past 10 years and expands on the processes that are used to estimate reserves. New techniques for assessing risk were also included. The book is divided into four parts entitled: (1) definitions and guidelines for estimating and classifying oil and gas resources and reserves, (2) determination of in-place resources, (3) estimation of recovery factors and forecasting of recoverable hydrocarbons, and (4) prices, economics and markets. The second edition includes new sections dealing with geostatistics, natural gas balance calculations, reserves estimates in naturally fractured reservoirs, and new developments in estimating recovery factors through enhanced recovery methods such as horizontal drilling. The objective was to develop a reference that is of great value to geologists, engineers and technical persons involved in estimating reserves. refs., tabs., figs

The tidal influence on oil and gas emissions from an abandoned oil well: Nearshore Summerland, California

Leifer, Ira; Wilson, Ken

2007-01-01

Oil and gas emissions were quantified for natural and human sources in nearshore waters off Summerland, California through deployment of custom designed collection tents. Seepage was measured at a repeatedly abandoned well, on the seabed from a caisson located along the historical location of the Treadwell Wharf, where the world's first off-shore oil wells were drilled at the end of the 19th century. Seepage rates at the capped T-10 Well, located in ∼5 m water, showed high correlation to tides. Site emissions were 2.4 and 38.7 L day -1 oil and gas, respectively. Emissions were measured from two areas of seepage at the T-10 Well Site. Oil and gas ratios were inversely correlated between the two seepage areas, demonstrating connectivity. Data were interpreted in terms of an electronic circuit model of seepage with respect to the time lag between local low tide and peak oil emissions

Their exports include specialized equipment for extracting oil sands, gathering and treatment facilities for sour gas, underbalanced drilling technologies, equipment for wells experiencing declining production rates, top motor drives, winter drilling rigs, and horizontal drilling technologies. They also offer petroleum industry software products. Most exploration and production equipment sold abroad by Canadian firms is manufactured in Canada, but there is an increasing trend toward manufacturing in the country of operation. 2 tabs

Highlights: • Three integrated oil shale refinery processes are proposed. • Techno-economic performance of three proposed processes is conducted and compared. • Competitiveness of the three proposed processes is investigated at different scenarios. • A development direction for oil shale refinery industry is suggested. - Abstract: Compared with the petrochemical industry, oil shale refinery industry is still relatively backward and has many shortcomings, such as poor quality of shale oil, inefficient utilization of retorting gas, and the unsatisfactory economic performance. In the situation of the low oil price, many oil shale refinery plants are forced to stop or cut production. Thus, oil shale industry is facing a severe problem. How to relieve monetary loss or turn it into profits? This paper proposes three integrated oil shale refinery processes: an integrated with hydrogen production from retorting gas, an integrated with hydrogenation of shale oil, and an integrated with hydrogen production and oil hydrogenation. The techno-economic performance of the three different processes is conducted and compared with that of a conventional oil shale process. Results show the exergy destruction ratio of the oil shale process integrated with hydrogen production from retorting gas is the least, 41.6%, followed by the oil shale process integrated with hydrogen production and oil hydrogenation, 45.9%. Furthermore, these two proposed processes have the best economic performance. Especially they can turn losses of the conventional oil shale process into profits at the situation of low oil price. The oil shale process integrated with hydrogen production from retorting gas is recommended to the oil shale plants which use the oil shale with oil content lower than 12.9%, while the plants using oil shale with oil content higher than 12.9% are better to select the oil shale process integrated with hydrogen production and oil hydrogenation.

Measuring Effective Tax Rates for Oil and Gas in Canada

Directory of Open Access Journals (Sweden)

Jack M. Mintz

2010-03-01

Full Text Available The purpose of this report is to provide cost of capital formulae for assessing the effects of taxation on the incentive to invest in oil and gas industries in Canada. The analysis is based on the assumption that businesses invest in capital until the after-tax rate of return on capital is equal to the tax-adjusted cost of capital. The cost of capital in absence of taxation is the inflation-adjusted cost of finance. The after-tax rate of return on capital is the annualized profit earned on a project net of the taxes paid by the businesses. For this purpose, we include corporate income, sales and other capital-related taxes as applied to oil and gas investments. For oil and gas taxation, it is necessary to account for royalties in a special way. Royalties are payment made by businesses for the right to extract oil and gas from land owned by the property holder. The land is owned by the province so the royalties are a rental payment for the benefit received from extracting the product from provincial lands. Thus, provincial royalty payments are a cost to oil and gas companies for using public property. However, since the provincial government is responsible for the royalty regime and could use taxes like the corporate income tax to extract revenue, one might think of royalties as part of the overall fiscal regime to raise revenue. In principle, one should subtract the rental benefit received from oil and gas businesses from taxes and royalty payments to assess the overall fiscal impact. This is impossible to do without measuring some explicit rental rate for use of provincial property. Further, royalty payments may distort economic decisions unlike a payment based on the economic rents earned on oil and gas projects. Instead, for comparability across jurisdictions, one might calculate the aggregate tax and royalty effective tax rates (such as between Alberta and Texas.

Characterization of a hydro-pneumatic suspension strut with gas-oil emulsion

Science.gov (United States)

Yin, Yuming; Rakheja, Subhash; Yang, Jue; Boileau, Paul-Emile

2018-06-01

The nonlinear stiffness and damping properties of a simple and low-cost design of a hydro-pneumatic suspension (HPS) strut that permits entrapment of gas into the hydraulic oil are characterized experimentally and analytically. The formulation of gas-oil emulsion is studied in the laboratory, and the variations in the bulk modulus and mass density of the emulsion are formulated as a function of the gas volume fraction. An analytical model of the HPS is formulated considering polytropic change in the gas state, seal friction, and the gas-oil emulsion flows through orifices and valves. The model is formulated considering one and two bleed orifices configurations of the strut. The measured data acquired under a nearly constant temperature are used to identify gas volume fraction of the emulsion, and friction and flow discharge coefficients as functions of the strut velocity and fluid pressure. The results suggested that single orifice configuration, owing to high fluid pressure, causes greater gas entrapment within the oil and thus significantly higher compressibility of the gas-oil emulsion. The model results obtained under different excitations in the 0.1-8 Hz frequency range showed reasonably good agreements with the measured stiffness and damping properties of the HPS strut. The results show that the variations in fluid compressibility and free gas volume cause increase in effective stiffness but considerable reduction in the damping in a highly nonlinear manner. Increasing the gas volume fraction resulted in substantial hysteresis in the force-deflection and force-velocity characteristics of the strut.

Most of the pipelines of oil and gas pipelines in our country have been for more than 25 years. These pipes are buried underground and was difficult to daily test. In addition, it was vulnerable to environmental, corrosion and natural disasters, So there is a hidden nature of accidents. The rapid development of urbanization, population accumulation, dense building and insufficient safety range are all the reasons for the frequent accidents of oil and gas pipelines. Therefore, to appraise and know the safe condition of the city various regions oil and gas pipelines is vital significant. In order to ensure the safety of oil and gas pipeline city, this paper defines the connotation of oil and gas pipeline city vulnerability according to the previous research on vulnerability. Then from three perspectives of environment, structure and behavior, based on the analytical paradigm of “structure—vulnerability conduct—performance” about oil and gas, the influential indicators of vulnerable oil and gas pipelines were analysed, the vulnerability mechanism framework of Oil and gas pipeline city was also constructed. Finally, the paper proposed the regulating strategy of the vulnerability of the oil and gas pipeline city to decrease its vulnerability index, which can be realize the city’s vulnerability evaluation and provides new ideas for the sustainable development of the city.

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

2008-01-01

It has been established that Naturally Occurring Radioactive Materials (NORM) may accumulate at various locations along the oil/gas production process. Components such as wellheads, separation vessels, pumps, and other processing equipment can become NORM contaminated, and NORM can accumulate in the form of sludge, scale, scrapings and other waste media. This can create a potential radiation hazard to workers, general public and the environment if certain controls are not established. Saudi Aramco has developed NORM management guidelines and is implementing a comprehensive strategy to address all aspects of NORM management which aim towards enhancing: NORM monitoring; Control of NORM contaminated equipment; Control over NORM waste handling and disposal; Workers protection, awareness, and training. The benefits of shared knowledge, best practice and, experience across the oil and gas industry are seen as key to the establishment of common guidance. This paper outlines Saudi Aramco's experience in the development of a NORM management strategy and its goals of establishing common guidance throughout the oil and gas industry. (author)

Biewick, Laura

2008-01-01

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

Suellentrop, Steve

1998-01-01

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)

Review on biofuel oil and gas production processes from microalgae

International Nuclear Information System (INIS)

Amin, Sarmidi

2009-01-01

Microalgae, as biomass, are a potential source of renewable energy, and they can be converted into energy such as biofuel oil and gas. This paper presents a brief review on the main conversion processes of microalgae becoming energy. Since microalgae have high water content, not all biomass energy conversion processes can be applied. By using thermochemical processes, oil and gas can be produced, and by using biochemical processes, ethanol and biodiesel can be produced. The properties of the microalgae product are almost similar to those of offish and vegetable oils, and therefore, it can be considered as a substitute of fossil oil.

Government spending on Canada's oil and gas industry : undermining Canada's Kyoto commitment

International Nuclear Information System (INIS)

Taylor, A.; Bramley, M.; Winfield, M.

2005-01-01

This study investigates government spending in the Canadian oil and gas industry within the context of greenhouse gas emission trends and Kyoto commitments. Various forms of provincial and federal government support provided between 1996 and 2002 through grants, tax expenditures, and government program expenditures for conventional oil and gas and oil sands sectors are presented. The paper contextualizes government support for oil and gas production, discusses what constitutes a subsidy, presents the methodology and approach used to establish expenditure estimates, presents the study findings and discusses expenditure estimates and puts the results into the context of other public policy work. The conclusion recommends policy changes and describes important areas for future research related to public expenditure on oil and gas production. The study concludes that while it is understood that reform or removal of environmentally harmful subsidies will not solve environmental problems alone, such actions are important in order to achieve environmental improvements and objectives. 163 refs., 24 tabs, 5 figs

Canada-United States oil and gas relations, 1958 to 1974

Science.gov (United States)

Nemeth, Tammy Lynn

While there were overtures from each country to develop a more formal accord to govern the trade of oil and natural gas at different times since 1958, Canada rejected that option in 1974 when it decided to phase out oil exports to the U.S. The main purpose of this research is to trace the development and evolution of Canada-U.S. oil and gas relations from the beginning of the informal continental relationship in 1959, through attempts to formalize a continental oil and gas agreement in the late 1960s, to the initial reversal of continentalism by Canada in 1974. This study examines and compares the changing influence of the explanatory variables of interest groups, international forces, national security, economics, ideas, and personalities on the energy decision- and policy-making processes of Canada and the U.S. between 1958 and 1974. Four key decisions or events that can be considered turning points in the Canada-U.S. oil and gas relationship are analysed and include: Canada's exemption to the American Mandatory Oil Import Program (MOIP); Canada's National Oil Policy (NOP); the near revocation of Canada's MOIP exemption; and Canada's decision to phase out oil exports. These events and relationships are situated in the larger context of interdependence, intergovernmental and transgovernmental relations, and the altered bureaucratic structures of governments in both countries over this period of time. Although decisions concerning Canada-U.S. oil and gas relations, and the pursuit and reversal of continentalist policies, were influenced by concerns regarding the pressure of various interest groups, international forces, national security, and changing economic and ideological circumstances; in the period examined here, the personalities of and personal relationships between Presidents and Prime Ministers, and the actions of key officials, as well as their transgovernmental networks across the border, often made the difference in determining what policy or approach

Oil and gas in British Columbia : 10 steps to responsible development

International Nuclear Information System (INIS)

2004-04-01

The British Columbia government has proposed to double production of oil and gas, the burning of which causes global warming. West Coast Environmental Law (WCEL) claims there is a strong divide between British Columbia's plans to expand the production and use of fossil fuels, and the international scientific consensus regarding the negative aspects of global warming. The impacts of oil and gas production negatively affect the health of local citizens, First Nations rights and the environment. Offshore oil and gas development could also threaten fisheries and pollute sensitive marine ecosystems. WCEL criticizes the fact that the British Columbia government has streamlined environmental regulations, has laid off compliance monitoring staff, and has given subsidies to the highly profitable oil and gas industry. WCEL argues that the impact of fossil fuel production must be mitigated to limit the damage to lands and people in British Columbia. The organization has proposed 10 recommendations to the British Columbia government. The recommendations focus on impacts of land-based oil and gas development rather than offshore impacts. WCEL claims that adoption of the 10-point mitigation plan is vital for putting British Columbia on the path toward sustainable development. 43 refs

2014-10-01

Emissions of volatile organic compounds (VOCs) associated with oil and natural gas production in the Uintah Basin, Utah were measured at a ground site in Horse Pool and from a NOAA mobile laboratory with PTR-MS instruments. The VOC compositions in the vicinity of individual gas and oil wells and other point sources such as evaporation ponds, compressor stations and injection wells are compared to the measurements at Horse Pool. High mixing ratios of aromatics, alkanes, cycloalkanes and methanol were observed for extended periods of time and for short-term spikes caused by local point sources. The mixing ratios during the time the mobile laboratory spent on the well pads were averaged. High mixing ratios were found close to all point sources, but gas well pads with collection and dehydration on the well pad were clearly associated with higher mixing ratios than other wells. The comparison of the VOC composition of the emissions from the oil and natural gas well pads showed that gas well pads without dehydration on the well pad compared well with the majority of the data at Horse Pool, and that oil well pads compared well with the rest of the ground site data. Oil well pads on average emit heavier compounds than gas well pads. The mobile laboratory measurements confirm the results from an emissions inventory: the main VOC source categories from individual point sources are dehydrators, oil and condensate tank flashing and pneumatic devices and pumps. Raw natural gas is emitted from the pneumatic devices and pumps and heavier VOC mixes from the tank flashings.

Radon gas in oil and natural gas production facilities

International Nuclear Information System (INIS)

Chandler, W.P.

1994-01-01

Radon gas is a naturally occurring radionuclide that can be found in some oil and natural gas production facilities, either as a contaminant in a natural gas stream or derived from Radium dissolved in formation waters. The gas itself is not normally a health hazard, but it's decay products, which can be concentrated by plate-out or deposition as a scale in process equipment, can be a health hazard for maintenance personnel. To evaluate possible health hazards, it is necessary to monitor for naturally occurring radioactive materials (NORM) in the gas stream and in the formation water. If Radon and/or Radium is found, a monitoring programme should be initiated to comply with National or State requirements. In some instances, it has been found necessary to dispose of silt and scale materials as low level radioactive waste. 8 refs

Oil and gas developments in western Canada in 1981

Energy Technology Data Exchange (ETDEWEB)

Hay, P.W.; Robertson, D.C.

1982-12-01

In 1981 there was a marked slump in drilling activity in western Canada, resulting from the combined effects of the National Energy Program (NEP), economic recession and a worldwide oil surplus. The number of wells drilled dropped by 22% to a total of 6,904. Exploratory drilling decreased 19% to 3,074 wells, and development drilling decreased 25% to 3,830 wells. The exploratory success rate also decreased to 62% in 1981, based on 740 oil discoveries and 1,172 gas discoveries. The development success rate decreased slightly to 88%, with 1,334 oil discoveries and 2,034 gas discoveries. Average well depth increased in four of the five western areas, but total revenue from land sales plummetted to half of the previous years' record totals. Average price per hectare also dropped. In Alberta, significant exploration activity was centred in the Shekilie, Golden-Evi and West Pembina areas, while major gas discoveries were made at Whiskey and Elmworth, and oil discoveries at Tangent. No significant new discoveries were made in British Columbia or Saskatchewan, but the 1980 Manitoba oil discovery at Waskada continued to stimulate activity. Preliminary results from the Nechako Basin drilling in central British Columbia proved to be disappointing with three successive dry holes. In the Arctic Islands, two major oil discoveries were made at Skate and Cisco, off Lougheed Island and a gas discovery at MacLean. Beaufort Sea drilling was hampered by weather, but nonetheless resulted in major oil discoveries a Koakoak and at a Kopanoar follow-up well. The year 1981 will probably be viewed as a major turning point in exploration in western Canada, with interest shifting from the provinces to the frontiers, and the participants now mainly Canadian-controlled companies.

In Situ Raman Spectroscopic Observations of Gas-Saturated Rising Oil droplets: Simulation with Decane as an Oil-Equivalent Substitute

Science.gov (United States)

Peltzer, E. T.; Walz, P. M.; Brewer, P. G.

2016-02-01

Oil droplets rising from the sea floor, whether from seeps or well leakage, contain very large quantities of dissolved gas that profoundly affects their density and critical oil-water interfacial characteristics. The primary dissolved gas is methane which may be up to 30% of the molar volume. This can create a hydrate skin as the methane gas is shed from the oil as it rises through the water column, thus decreasing in pressure and increasing in temperature, and steadily changing the rising droplet buoyancy. We have explored this phenomenon by executing controlled ROV based experiments with a "bubble cup" technique in which a small volume of gas saturated decane (saturated with pure methane, a mix of methane and nitrogen , or a mix of methane and CO2) is interrogated by laser Raman spectroscopy. The use of decane as an oil "substitute" is required since natural oil samples are highly fluorescent due to the presence of polycyclic aromatic hydrocarbons. We have devised Matlab techniques for extracting the spectroscopic dissolved methane signal from the thicket of decane peaks that surround it. We have directly observed the rate at which gases are lost from the "oil" per unit area at depths in the water column that are both within and outside the hydrate forming phase boundary. We have compared the behavior of both a non-hydrate forming dissolved gas (nitrogen) with CO2 where the hydrate phase boundary is at significantly shallower depth. The results indicate complex interfacial behavior and physical chemistry. We did not observe direct gas bubble formation on the decane outer surface but did observe gas bubble formation within the oil droplets as they rose through the water column. Because there are significant energy barriers for homogeneous bubble formation within the decane phase, we took this as evidence of significant gas super-saturation within the oil droplet. The gas loss rates increased significantly in all cases when the hydrate phase boundary was crossed.

Dorning, Monica; Garman, Steven L.; Diffendorfer, James E.; Semmens, Darius J.; Hawbaker, Todd J.; Bagstad, Kenneth J.

2017-01-01

Development from extracting oil and gas resources can have unintended effects on multiple ecosystem functions, with cascading effects on wildlife, ecosystem services, and local economies. Big-game hunting opportunities may be closely related to these effects, but empirical analyses of impacts of energy development on hunting are limited. We examined the influence of oil and gas development density on harvest efficiency, or harvest per unit of hunter effort, within all hunt areas in Wyoming, USA, from 2008 to 2014 for 3 big-game species: elk (Cervus canadensis), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana). Using harvest/hunter day as the response variable, we compared linear mixed-effects models for each species that included total well density (i.e., all wells constructed up to the year of record), active well density (i.e., only those wells currently producing oil or gas in that year), or neither as a predictor variable. We used well densities as indicators of development in the absence of data specifying the locations of other oil and gas infrastructure (e.g., roads, well pads). Models also accounted for the fixed effects of road density, hunter density, proportion of the area that is public land with unrestricted hunter access, proportion of the area that is forested, year of observation, and random effects of variation among hunt areas nested within associated game herd units. Presence of oil and gas wells had a positive influence on harvest efficiency for elk and mule deer. Although there was no overall effect to pronghorn, there was a negative influence of wells on juvenile pronghorn harvest efficiency. Changes in harvest efficiency due to expanding oil and gas development could alter the time spent hunting by hunters and their chances of harvesting an animal. This could have subsequent impacts on hunter satisfaction, game populations, and economic revenue generated from recreational hunters.

Environmental risk analysis for offshore oil and gas activities

Energy Technology Data Exchange (ETDEWEB)

Brude, Odd Willy; Aspholm, Ole O.; Rudberg, Anders [Det Norske Veritas (Brazil)

2008-07-01

Offshore oil and gas activities always have a risk for environmental impact due to potential accidental releases of oil and gas. The environmental risk can be calculated as a combination of the frequency of such accidents to occur and their environmental consequences in terms of environmental damage to habitats or populations. A method for conducting environmental risk analysis has been in use in Norwegian offshore waters for a decade, with a continuously refinement of methodology over the past years. This paper outlines the principles in the MIRA method and gives examples and discussions regarding use in different environmental compartments. The risk assessment starts with identification of oil spill scenarios with frequencies of potential release rates and spill durations. The next step is to model the oil drift for each accidental oil spill scenario. Drift and fate of oil is modeled probabilistic. Based on the oil spill scenarios and their probability of oil pollution, the potential environmental damage is quantified for each scenario. The endpoint of environmental damage is reduction of a population and the resulting recovery time (in years) for various species and habitats. Environmental risk levels are then evaluated against the operating companies' environmental acceptance criteria. (author)

A competitor today is an ally tomorrow. A strategic partner in one market is an adversary in another. In this radically new way of doing business, the oil and gas industry seems quite at home. The trend to mergers is not unique to the oil industry, what is unique is the knack of petroleum companies to form strategic alliances [it

Rethink potential risks of toxic emissions from natural gas and oil mining.

Studies have showed the increasing environmental and public health risks of toxic emissions from natural gas and oil mining, which have become even worse as fracking is becoming a dominant approach in current natural gas extraction. However, governments and communities often overlook the serious air pollutants from oil and gas mining, which are often quantified lower than the significant levels of adverse health effects. Therefore, we are facing a challenging dilemma: how could we clearly understand the potential risks of air toxics from natural gas and oil mining. This short study aims at the design and application of simple and robust methods to enhance and improve current understanding of the becoming worse toxic air emissions from natural gas and oil mining as fracking is becoming the major approach. Two simple ratios, the min-to-national-average and the max-to-national-average, are designed and applied to each type of air pollutants in a natural gas and oil mining region. The two ratios directly indicate how significantly high a type of air pollutant could be due to natural gas and oil mining by comparing it to the national average records, although it may not reach the significant risks of adverse health effects according to current risk screening methods. The min-to-national-average and the max-to-national-average ratios can be used as a direct and powerful method to describe the significance of air pollution by comparing it to the national average. The two ratios are easy to use for governments, stakeholders, and the public to pay enough attention on the air pollutants from natural gas and oil mining. The two ratios can also be thematically mapped at sampled sites for spatial monitoring, but spatial mitigation and analysis of environmental and health risks need other measurements of environmental and demographic characteristics across a natural gas and oil mining area.

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.

Gas cleaning and hydrogen sulfide removal for COREX coal gas by sorption enhanced catalytic oxidation over recyclable activated carbon desulfurizer.

This paper proposes a novel self-developed JTS-01 desulfurizer and JZC-80 alkaline adsorbent for H2S removal and gas cleaning of the COREX coal gas in small-scale and commercial desulfurizing devices. JTS-01 desulfurizer was loaded with metal oxide (i.e., ferric oxides) catalysts on the surface of activated carbons (AC), and the catalyst capacity was improved dramatically by means of ultrasonically assisted impregnation. Consequently, the sulfur saturation capacity and sulfur capacity breakthrough increased by 30.3% and 27.9%, respectively. The whole desulfurizing process combined selective adsorption with catalytic oxidation. Moreover, JZC-80 adsorbent can effectively remove impurities such as HCl, HF, HCN, and ash in the COREX coal gas, stabilizing the system pressure drop. The JTS-01 desulfurizer and JZC-80 adsorbent have been successfully applied for the COREX coal gas cleaning in the commercial plant at Baosteel, Shanghai. The sulfur capacity of JTS-01 desulfurizer can reach more than 50% in industrial applications. Compared with the conventional dry desulfurization process, the modified AC desulfurizers have more merit, especially in terms of the JTS-01 desulfurizer with higher sulfur capacity and low pressure drop. Thus, this sorption enhanced catalytic desulfurization has promising prospects for H2S removal and other gas cleaning.

The lack of a high capacity hydrogen storage material is a major barrier to the implementation of the hydrogen economy. To accelerate discovery of such materials, we have developed a high-throughput workflow for screening of hydrogen storage materials in which candidate materials are synthesized and characterized via highly parallel ball mills and volumetric gas sorption instruments, respectively. The workflow was used to identify mixed imides with significantly enhanced absorption rates relative to Li2Mg(NH)2. The most promising material, 2LiNH2:MgH2 + 5 atom % LiBH4 + 0.5 atom % La, exhibits the best balance of absorption rate, capacity, and cycle-life, absorbing >4 wt % H2 in 1 h at 120 °C after 11 absorption-desorption cycles.

Crude oil and natural gas supplies and demands for Denmark

Mackay, R.M.; Probert, S.D.

1995-01-01

A novel technique for forecasting the supply and extraction life-cycle of a depleting fossil fuel resource has been developed. The supply side utilises a 'skewed-normal production-profile' model that yields a better representation than earlier approaches. A simple model for extrapolating crude oil and natural gas demands has also been devised, based on the so called 'modified logit function'. The predicted crude oil and natural gas balances for the period up to AD 2010 indicate the disparity between indigenous production and future consumption for Denmark. These forecasts depend on current estimates of remaining oil and gas reserves. It will consequently be necessary to revise periodically the present projections as more reliable reserve estimates become available. (author)

Visualization of Solution Gas Drive in Viscous Oil, SUPRI TR-126

Energy Technology Data Exchange (ETDEWEB)

George, D.S.; Kovscek, A.R.

2001-07-23

Several experimental studies of solution gas drive are available in this report. Almost all of the studies have used light oil. Solution gas drive behavior, especially in heavy oil reservoirs, is poorly understood. Experiments were performed in which pore-scale solution gas drive phenomena were viewed in water/carbon dioxide and viscous oil/carbon dioxide systems. A new pressure vessel was designed and constructed to house silicon-wafer micromodels that previously operated at low (<3 atm) pressure. The new apparatus is used for the visual studies. Several interesting phenomena were viewed. The repeated nucleation of gas bubbles was observed at a gas-wet site occupied by dirt. Interestingly, the dissolution of a gas bubble into the liquid phase was previously recorded at the same nucleation site. Gas bubbles in both systems grew to span one ore more pore bodies before mobilization. Liquid viscosity affected the ease with which gas bubbles coalesced. More viscous solutions result in slower rates of coalescence. The transport of solid particles on gas-liquid interfaces was also observed.

The state of oil and gas production in each of twelve Arab states in 1996 is reviewed. A table of proved oil reserves and production in these countries as at the end of 1995 is provided. For Arab oil producers, 1996 was a good year in price terms. Crude oil was selling at an average of $3 a barrel more than in 1995. Factors contributing to prices rises were the increase in demand accompanying global economic growth, especially in the developing economies of Asia, which was not matched by supply growth, and the news that Iraq is unlikely to return to international markets in the near future.

2004-01-01

Straight chain fatty alcohols having the following number of carbon atoms C 12 , C 14 , C 18 and C 21 each alcohol was ethoxylated to the same of ethylene oxide content, characterized through average molecular weight and elemental analysis. The surface properties of these compounds were studied through surface tension measurements. The synthesized additives were tested as flow improvers for improving the cold flow properties of two waxy gas oils through pour point test. The results show the right efficiency of these compounds in improving the flow ability. Comparative evaluation of the synthesized products with available commercial additive (com) showed their efficiency and suitability to use in gas oils. Wax modification was assisted through photo analysis. Correlation between wax modification and flow improvement in term of pour point depression appeared to be merely qualitative in such heterogeneous gas oil systems

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.

A system dynamic model for production and consumption policy in Iran oil and gas sector

International Nuclear Information System (INIS)

Kiani, Behdad; Ali Pourfakhraei, Mohammad

2010-01-01

A system dynamic model is presented, which considers the feedback between supply and demand and oil revenue of the existing system in Iran considering different sectors of the economy. Also the export of the oil surplus and the injection of the gas surplus into the oil reservoirs are seen in the model by establishing a balance between supply and demand. In this model the counter-effects and existing system feedbacks between supply and demand and oil revenue can be seen considering different sectors of the economy. As a result, the effects of oil and gas policies in different scenarios for different sectors of Iran's economy together with the counter-effects of energy consumption and oil revenue are examined. Three scenarios, which show the worst, base and ideal cases, are considered to find future trends of major variables such as seasonal gas consumption in power plants, seasonal injected gas in oil reservoirs, economic growth in the industrial sector, oil consumption in the transportation sector, industrial gas consumption and exported gas. For example, it is shown that the exported gas will reach between 500 and 620 million cubic-meter per day in different scenarios and export revenues can reach up to $500 billion by 2025. - Research Highlights: →A system dynamic model analyzing the feedback between supply, demand and oil revenue is built. →The export of the oil surplus and the injection of the gas surplus into oil reservoirs are modeled. →Effects of oil and gas policies in different scenarios are examined for Iran's economy. →Counter-effects of energy consumption and oil revenue are examined. →Exported gas will reach between 500 and 620 million cubic-meter per day in different scenarios. →Export revenues can reach up to $500 billion by 2025.

These lands cover some 10.2 million km 2 and include the Northwest Territories, Yukon Territory, and areas off the east and west coasts and in the far north. A statistical summary is presented of oil and gas activities in these frontier lands for 1992. Information provided includes activity status and wells drilled on frontier lands, a resource inventory, oil and gas production, land holdings and status, licenses concluded, petroleum-related employment on frontier lands, and petroleum expenditures on frontier lands. Highlights of activities include the first commercial production of crude oil from the Panuke oil field on the Scotian Shelf; a continued decrease in exploration activity on the frontier lands; the introduction of legislation to eliminate restrictions on foreign ownership of production licences on frontier lands; and the resolution to the Canada-France maritime boundary dispute by the International Court of Arbitration. 9 figs., 10 tabs

Shale Gas and Tight Oil: A Panacea for the Energy Woes of America?

Science.gov (United States)

Hughes, J. D.

2012-12-01

Shale gas has been heralded as a "game changer" in the struggle to meet America's demand for energy. The "Pickens Plan" of Texas oil and gas pioneer T.Boone Pickens suggests that gas can replace coal for much of U.S. electricity generation, and oil for, at least, truck transportation1. Industry lobby groups such as ANGA declare "that the dream of clean, abundant, home grown energy is now reality"2. In Canada, politicians in British Columbia are racing to export the virtual bounty of shale gas via LNG to Asia (despite the fact that Canadian gas production is down 16 percent from its 2001 peak). And the EIA has forecast that the U.S. will become a net exporter of gas by 20213. Similarly, recent reports from Citigroup and Harvard suggest that an oil glut is on the horizon thanks in part to the application of fracking technology to formerly inaccessible low permeability tight oil plays. The fundamentals of well costs and declines belie this optimism. Shale gas is expensive gas. In the early days it was declared that "continuous plays" like shale gas were "manufacturing operations", and that geology didn't matter. One could drill a well anywhere, it was suggested, and expect consistent production. Unfortunately, Mother Nature always has the last word, and inevitably the vast expanses of purported potential shale gas resources contracted to "core" areas, where geological conditions were optimal. The cost to produce shale gas ranges from 4.00 per thousand cubic feet (mcf) to 10.00, depending on the play. Natural gas production is a story about declines which now amount to 32% per year in the U.S. So 22 billion cubic feet per day of production now has to be replaced each year to keep overall production flat. At current prices of 2.50/mcf, industry is short about 50 billion per year in cash flow to make this happen4. As a result I expect falling production and rising prices in the near to medium term. Similarly, tight oil plays in North Dakota and Texas have been heralded

Sorption of cadmium and lead by clays from municipal incinerator ash- water suspensions

Science.gov (United States)

Roy, W.R.; Krapac, I.G.; Steele, J.D.

1993-01-01

The effect of Cl complexation in extracts of a flue gas-scrubber incinerator fly ash sample on the sorption of Cd and Pb by kaolinite and illite was investigated using batch-sorption methods. In the pH range of 5 to 9, Cl complexation may reduce sorption and thus increase the mobility of these metals. When an ash-water suspension was acidified to pH 6.85, the dissolution of Cl and Ca essentially eliminated Cd sorption because of complexation and cationic competition. Cadmium would be considered as either mobile or very mobile under these conditions. Lead was not soluble in the pH- 6.85 suspension. At pH 12, the approximate pH of water in contact with flue gas-scrubber fly ash, Cd was essentially insoluble and Pb occurred as anionic Pb hydroxide. Anionic Pb was sorbed by the two clays, and the extent of sorption was not influenced by Cl or carbonate complexation. Sorption constants, derived from isotherms, suggested that Pb would be relatively immobile in saturated soil-water systems. The recent concern that highly alkaline, flue gas-scrubber fly ash may release environmentally significant concentrations of mobile Pb when placed in an ash-disposal site with a soil liner should be reevaluated in light of this study.

Technologically enhanced naturally occurring radioactive materials (TENORM) are present in components of both oil and natural gas production facilities. TENORM can be associated with the presence of crude oil, produced water and natural gas. The radiation exposure pathways to the workers in oil and gas production are similar to those in the uranium and heavy mineral sand mining and processing industry. This paper work provides a short review on the Specific Radiological Monitoring (SRM) program were carried out at oil and gas platforms in the east cost of Peninsular Malaysia. The objective of this paper work is to observe the monitoring parameters levels and to evaluate whether these levels are exceeding the limits set by Atomic Energy Licensing Board (AELB). The monitoring results showed that the surface contamination, airborne contamination and concentration of radon and thoron are well below the set limit stipulated in LEM/TEK/30 SEM.2, except for external radiation and radioactivity concentration of sludge and scales. About 2 (2.35%) from the 85 external radiation measurements performed were found above the permissible limit. While about 11 (36.6%) and 7 (23.3%) of the 30 collected sludge and scales samples were found containing higher Ra-226 and Ra-228, respectively, than the mean concentrations in normal soils of Peninsular Malaysia. In general, it can be concluded that a few of oil and gas production platform are producing TENORM. (Author)

Golden age: marketers extract the most from oil and natural gas trade

Lorenz, A.

2000-04-01

The complexity of the oil and natural gas markets, the complex factors which interact to produce the price of oil or natural gas on any given day, and the role of marketers in this high stakes game are discussed. While oil and natural gas prices are very good today compared to the low prices through much of the 1990s, marketers are now concerned about the ability of Canadian fields to produce enough to fill the expanded pipelines and meet the rising demand. As the oil and natural gas industry in Canada is moving from a pipeline-constrained environment to a resource-constrained environment, the question of declining reserves in the Western Canadian Sedimentary Basin and the resulting surplus in pipeline capacity is one of the most serious issues facing industry in the immediate future. This is especially true of natural gas where the cost of transportation, which can be as high as 30 per cent, is one of major importance to gas marketers. Locking in prices or allowing prices to float can make the difference between huge losses or gains depending on the interplay of the various factor that influence price fluctuations. Examples of how decisions about oil and gas prices are made, and the various outcomes that may result from marketer decisions are described to illustrate the vagaries of the natural gas market.

The article analyses Russia's Eastern energy strategy in the sectors of oil and natural gas, presenting its main aspects and examining it from the security perspective against the backdrop of official Russian documents. The goals set by the strategy are compared with the steps presently taken and planned by the Russian administration, as well as with short- and medium-term Russian energy policies in the sectors of oil and natural gas. The authors conclude that implementation of the Energy Strategy to 2030 in the sectors of oil and natural gas will be highly complicated in the Eastern vector of Russian politics and achievable only if new deposits are found. - Highlights: ► We compare goals of the Russia's Eastern energy strategy in the sectors of oil and natural gas with real policy.► In the Eastern vector are included China, both Korean states and Japan. ► For Russia's energy strategy to 2030 the Eastern market in the sector of oil and natural gas is advantageous and desirable. ► The present conditions can bring economic as well as political risks.

Shale Gas and Oil in Germany - Resources and Environmental Impacts

2017-04-01

In light of the controversial debate on "unconventional" oil and gas resources and the environmental impacts of "fracking", the Federal Institute for Geosciences and Natural Resources (BGR) conducted a comprehensive resource assessment of shale gas and light tight oil in Germany and studied the potential environmental impacts of shale gas development and hydraulic fracturing from a geoscientific perspective. Here, we present our final results (BGR 2016), incorporating the majority of potential shale source rock formations in Germany. Besides shale gas, light tight oil has been assessed. According to our set of criteria - i.e. thermal maturity 0.6-1.2 %vitrinite reflectance (VR; oil) and >1.2 % VR (gas) respectively, organic carbon content > 2%, depth between 500/1000 m and 5000 m as well as a net thickness >20 m - seven potentially generative shale formations were indentified, the most important of them being the Lower Jurassic (Toarcian) Posidonia shale with both shale gas and tight oil potential. The North German basin is by far the most prolific basin. The resource assessment was carried out using a volumetric in-place approach. Variability inherent in the input parameters was accounted for using Monte-Carlo simulations. Technically recoverable resources (TRR) were estimated using recent, production-based recovery factors of North American shale plays and also employing Monte-Carlo simulations. In total, shale gas TRR range between 320 and 2030 bcm and tight oil TRR between 13 and 164 Mio. t in Germany. Tight oil potential is therefore considered minor, whereas the shale gas potential exceeds that of conventional resources by far. Furthermore an overview of numerical transport modelling approaches concerning environmental impacts of the hydraulic fracturing is given. These simulations are based on a representative lithostratigraphy model of the North-German basin, where major shale plays can be expected. Numerical hydrogeological modelling of frac fluid

North Sea oil and gas: a geographical perspective

Energy Technology Data Exchange (ETDEWEB)

Chapman, K

1976-01-01

Only ten years after the first rig moved into position, British oil has been piped ashore from the North Sea and, by 1980, will be making a substantial contribution to UK energy supplies. The discovery of natural gas in 1967--for initially gas was the primary objective--has transformed the gas supply so that 90% of the UK's needs already come from the North Sea. The speed and concentration of exploration pinpoints the vital importance of this new energy source. Until now the major oil 'pipeline' in the world has been led between the Middle East and Western Europe, so this new energy source has far reaching implications, both political and economic. Keith Chapman examines these implications starting from events in the North Sea itself; the geological background, agreement on the division of the North Sea, relations between oil companies, and government embodied in offshore mining legislation. The latter part of the book concentrates on the onshore repercussions of offshore activities; how North Sea oil fits into the international oil system, the various options open for its utilisation, the attitude of the EEC towards Scottish-based resources, government policy for the North coast of Scotland--an area which planners classed as ''peripheral'' but which must now accommodate extensive support facilities and service industries for the oil sites. There is also the question of relations between national and commercial interests--government versus the giant multi-national companies which took the initial gamble in the North Sea and are now responsible for the development of a resource vital to the economic well-being of Western Europe.

Sorption mechanisms and sorption models

Sorption at the solid-liquid interfaces play a major role in many phenomena and technologies: chemical separations, catalysis, biological processes, transport of toxic and radioactive species in surface and underground waters. The long term safety of radioactive waste repositories is based on artificial and natural barriers, intended to sorb radionuclides after the moment when the storage matrixes and containers will be corroded. Predictions on the efficiency of sorption for more than 10 6 years have to be done in order to demonstrate the safety of such depositories, what is a goal never encountered in the history of sciences and technology. For all these purposes, and, especially for the long term prediction, acquiring of sorption data constitutes only a first step of studies. Modeling based on a very good knowledge of sorption mechanisms is needed. In this review, we shall examine the main approaches and models used to quantify sorption processes, including results taken from the literature and from our own studies. We shall compare sorption models and examine their adequacy with sorption mechanisms. The cited references are only a few examples of the numerous articles published in that field. (orig.)

The first letter is concerned with the issue of de-linking oil and gas. It is argued that the introduction of an ecotax, far from its creators' intentions, may deter investment in the natural gas industry to the benefit of coal and oil producers, rather than promoting gas as the fuel which best protects the environment. The second writer points out the Middle East's geographical disadvantage in aiming to supply natural gas to Europe. While reserves are ample, they are also readily available closer to European consumers, and without extra transportation costs. Markets nearby are either already functioning or, in areas such as India or Pakistan, prohibitively expensive in terms of pipeline construction or other technology. The last author also argues for investment in large-scale pipeline projects in order to use the Middle Eastern gas reserves, but stresses the need for political and security problems to be addressed at the same time.

A Bootstrap Approach to Computing Uncertainty in Inferred Oil and Gas Reserve Estimates

International Nuclear Information System (INIS)

Attanasi, Emil D.; Coburn, Timothy C.

2004-01-01

This study develops confidence intervals for estimates of inferred oil and gas reserves based on bootstrap procedures. Inferred reserves are expected additions to proved reserves in previously discovered conventional oil and gas fields. Estimates of inferred reserves accounted for 65% of the total oil and 34% of the total gas assessed in the U.S. Geological Survey's 1995 National Assessment of oil and gas in US onshore and State offshore areas. When the same computational methods used in the 1995 Assessment are applied to more recent data, the 80-year (from 1997 through 2076) inferred reserve estimates for pre-1997 discoveries located in the lower 48 onshore and state offshore areas amounted to a total of 39.7 billion barrels of oil (BBO) and 293 trillion cubic feet (TCF) of gas. The 90% confidence interval about the oil estimate derived from the bootstrap approach is 22.4 BBO to 69.5 BBO. The comparable 90% confidence interval for the inferred gas reserve estimate is 217 TCF to 413 TCF. The 90% confidence interval describes the uncertainty that should be attached to the estimates. It also provides a basis for developing scenarios to explore the implications for energy policy analysis

In the cracking of hydrocarbon oils, the thermal decomposition of fats to obtain glycerine, the production of oil and coal gas, and the destructive distillation of coal, peat, shale, etc., the lower molecular weight products are separated, while the higher molecular weight products are separated, while the higher molecular weight products and undecomposed substances are retained for further exposure to the decomposition conditions, by interposing one or more porous septa between the decomposition chamber and the condenser or receiver. The decomposition conditions may be maintained up to the porous septum; but it is preferable to place the porous septum in a separate chamber inside or outside the decomposition vessel; and a plurality of decomposition chambers may be used in series or parallel.

2014-01-01

Full Text Available Flow velocity measurement was an important research of oil-gas-water three-phase flow parameter measurements. In order to satisfy the increasing demands for flow detection technology, the paper presented a gas-liquid phase flow velocity measurement method which was based on energy demodulation algorithm combing with time delay estimation technology. First, a gas-liquid phase separation method of oil-gas-water three-phase flow based on energy demodulation algorithm and blind signal separation technology was proposed. The separation of oil-gas-water three-phase signals which were sampled by conductance sensor performed well, so the gas-phase signal and the liquid-phase signal were obtained. Second, we used the time delay estimation technology to get the delay time of gas-phase signals and liquid-phase signals, respectively, and the gas-phase velocity and the liquid-phase velocity were derived. At last, the experiment was performed at oil-gas-water three-phase flow loop, and the results indicated that the measurement errors met the need of velocity measurement. So it provided a feasible method for gas-liquid phase velocity measurement of the oil-gas-water three-phase flow.

Jacksonville Electric Authority's (JEA's) Northside station Unit 1 (NS-1) is now modified to fire natural gas as well as the original No. 6 fuel oil. Hardware and control modifications accommodate oil, gas. or simultaneous oil and gas firing in the boiler. Working with Stone and Webster Engineering Corporation, this flexibility derives from control modifications not previously used in North American power plants. This paper reports that the modifications not only reduce fuel costs, but also increase flexibility in meeting air emissions requirements. Emission levels for particulate and nitrous oxides (NO x ) on oil were demonstrated prior to the modification. No emission increases are allowed as a result of the modification in any firing mode. Particulate emission limits in pounds per million British thermal units (lb/mmBtu) are 0.1/mm Btu and NO x limits are 0.45 lb/mmBtu. No x emissions from gas firing are also stipulated to be below oil emission limits

Kazakhstan is endowed with significant oil and gas resources and is expected to become one of the world's top 10 oil producers within the next decade. The high cost of doing business in the country, however, means that Kazakhstan will need to improve its institutional framework to successfully compete for Western investment. A large degree of risk and uncertainty continues to plague the oil and gas sector as the government makes significant changes to the petroleum tax legislation and takes an aggressive approach in 'rebalancing' contractual arrangements with industry. High levels of bureaucracy, regulatory burden, and corruption persist, and economic factors appear to be subordinated increasingly to geopolitical objectives aimed to strengthen relationships with China and Russia. The rapid pace of change and the high degree of uncertainty present significant challenges and risk to foreign investment. The purpose of this paper is to review the oil and gas sector in Kazakhstan and highlight recent developments in the petroleum legislation, business climate and government policy

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

A first: U.S. natural gas wellhead value tops oil's

International Nuclear Information System (INIS)

Anon.

1994-01-01

The value of natural gas production in the US in 1993 exceeded that of crude oil output for the first time in history. The reversal owes as much to trends in price as in production and, most recently, record frigid weather in much of the US. Another key factor is a newly revitalized, restructured gas industry operating in the most unfettered regulatory environment in recent memory. The industry's sterling performance in accommodating the surge in demand caused by the arctic cold that steamrolled across North America early in the 1993--94 winter strengthens the natural gas case for reliability. And that can only enhance the industry's prospects for adding more long term supply contracts. Looming on the immediate horizon is the prospect of an extended slump in oil prices, which could mean that natural gas dominance in US petroleum industry revenues will be short lived if low cost oil recaptures market share from gas. While that may temporarily dethrone natural gas from its new top slot, the reversal in 1993 represents what is likely to be a long term trend for the US petroleum industry

A Study on the Current Oil and Gas Price Formula and Its Improvement

The object of this study is to suggest some improvements on current price formulas on oil and gas which have been pivotal roles in the process of Korean economic growth. This study first examines basic frames and transition of oil and gas pricing in Korea and then finds some suggestions on them by scrutinizing their theoretical backgrounds. This study finds several problems on oil and gas pricing formulas. (a) In a model that is now studied to evaluate the current domestic oil price, the costs associated with oil security such as oil stockpile are fully penetrated into oil price without their fair evaluations. There is no evaluation principle on the costs occurred in oil supply security. (b) The Rate Of Equity(ROE), a crucial factor in town-gas pricing which is strictly controlled, is directly connected to the average interest rate on saving accounts of domestic commercial banks. Some arguments may have rise about inclusion a risk factor on ROE in order to compensate the uncertainty of town-gas business. (c) New demand for natural gas which is generated by new technologies or machinery and tools can help reduce the costs occurred from seasonal imbalance between power sector and gas sector. So it is also important to decide how to include the beneficiary of cost reduction in town-gas pricing. In order to evaluate the proper price levels, this study tests energy supply security by adopting methodologies such as Herfindahl Index and Portfolio Variance Risk. They can help develop the method to effectively improve the energy security and include the proper energy security costs into energy prices. This study also provides some suggestions for betterment of current ROE decision rule in town-gas business and for improvement of current town-gas policy that government subsidizes newly developed demand for strengthening price competitiveness in the early stage.

Jiang, Wanfeng; Zhang, Ning; Zhang, Fengyan; Yang, Zhao

2017-07-08

A method for the determination of the content of olive oil in olive blend oil by headspace gas chromatography-mass spectrometry (SH-GC/MS) was established. The amount of the sample, the heating temperature, the heating time, the amount of injection, the injection mode and the chromatographic column were optimized. The characteristic compounds of olive oil were found by chemometric method. A sample of 1.0 g was placed in a 20 mL headspace flask, and heated at 180℃ for 2700 s. Then, 1.0 mL headspace gas was taken into the instrument. An HP-88 chromatographic column was used for the separation and the analysis was performed by GC/MS. The results showed that the linear range was 0-100%(olive oil content). The linear correlation coefficient ( r 2 ) was more than 0.995, and the limits of detection were 1.26%-2.13%. The deviations of olive oil contents in the olive blend oil were from -0.65% to 1.02%, with the relative deviations from -1.3% to 6.8% and the relative standard deviations from 1.18% to 4.26% ( n =6). The method is simple, rapid, environment friendly, sensitive and accurate. It is suitable for the determination of the content of olive oil in olive blend oil.

The US Shale Gas Revolution and Its Externality on Crude Oil Prices: A Counterfactual Analysis

Directory of Open Access Journals (Sweden)

Hongxun Liu

2018-03-01

Full Text Available The expansion of shale gas production since the mid-2000s which is commonly referred to as “shale gas revolution” has had large impacts on global energy outlook. The impact is particularly substantial when it comes to the oil market because natural gas and oil are substitutes in consumption and complements and rivals in production. This paper investigates the price externality of shale gas revolution on crude oil. Applying a structural vector autoregressive model (VAR model, the effect of natural gas production on real oil price is identified in particular, and then based on the identification, counterfactuals of oil price without shale gas revolution are constructed. We find that after the expansion of shale gas production, the real West Texas Intermediate (WTI oil price is depressed by 10.22 USD/barrel on average from 2007 to 2017, and the magnitude seems to increase with time. In addition, the period before shale gas revolution is used as a “thought experiment” for placebo study. The results support the hypothesis that real WTI oil price can be reasonably reproduced by our models, and the estimated gap for oil price during 2007–2017 can be attributed to shale gas revolution. The methodology and framework can be applied to evaluate the economic impacts of other programs or policies.

The gas price continues to be linked to the oil price. Gas utilities that must buy gas in these conditions and sell it at a fixed price incur considerable financial risk. Especially with long-term buying contracts, and especially for gas from Russia, producers insist on linking to the oil price. Gas utilities, on the other hand, had to stop to sell gas at a price linked to the oil price two years ago. Utilities attempt to protect themselves, e.g. via oil swaps. Professional portfolio management is necessary to cope with the risks and the highly complex processes involved.

This is a study of bio-oil generated by fast pyrolysis; a biomass feedstock is heated to pyrolyze at a rapid rate, the gas pyrolyzed is then condensed rapidly. The interesting result is a potential alternative fuel oil. An analysis was made of the effects of the initial pyrolysis gas temperatures, the initial bio-oil droplets temperatures and diameters, and the flow ratio of the gas and the liquid droplets on the heat and mass transfer between the gas and the liquid droplets. A few criterion equations were achieved with respect to the spray condenser. This paper established the gas-liquid phase equilibrium of an aqueous multi-composition system and the spray condensation model coupling heat and mass transfer. Model calculation and analysis showed that: spray condensation can effectively cool the high-temperature pyrolysis gas quickly; with gas liquid flowing, mass transfer rate reduces; and the relationship of gas and liquid flow ratio can achieve good accuracy.

1994-01-01

International government chartered banks are playing an increasingly prominent role in lending for world oil and gas development projects. The main players are the World Bank's International Finance Corp. (IFC), European Bank for Reconstruction and Development (EBRD), US Export-Import Bank, and Overseas Private Investment Corp. (OPIC). Those institutions and similar ones are the catalysts for a large number of projects in the former Soviet Union (FSU) and in other nations that are seeking to develop oil and gas resources and build processing plants, pipelines, and distribution networks. Banks also are taking a greater degree of interest in the environmental aspects of projects. In country after country, especially in the developing world, barriers to foreign investment in domestic petroleum sectors are falling. Oil and gas law reforms are under way on each continent. The paper discusses the major players, the World Bank grouped, the Romanian example, the Ex-Im Bank, OPIC, the emphasis on FSU, environmental issues, and new sources of capital in developing countries

The oil and gas industry uses many radiation sources in various radiation based technologies which are of great benefit to the industry, this includes nucleonic gauges, multiphase flow meters, well logging etc. Inappropriate use of these equipment and installations and uncontrolled activities associated with naturally occurring radioactive materials (NORM) can contaminate the environment resulting in occupational and public exposures. The objective of this work is to develop a Radiation Protection Programme (RPP) for the oil and gas industry which when implemented by the operating organisation will keep doses to the workers and public as low as reasonably achievable (ALARA), maximize the benefits while minimizing the hazards associated with the use of radiation based technologies. In order to achieve the aim of this work, review of previous works on radiation sources in nucleonic gauges, well logging and waste management processes of NORMs was carried out. Some recommendations were stated, which if strictly implemented would improve the scope of radiation protection in the oil and gas industries. (au)

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

1980-04-01

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

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

The regional economic impact of oil and gas extraction in Texas

This paper empirically investigates the regional economic impact of oil and gas extraction in Texas during the recent shale oil boom. Regressions with county-level data over the period 2009–2014 support smaller multiplier effects on local employment and income than corresponding estimates drawn from popular input–output-based studies. Economic impacts were larger for extraction from gas wells than oil wells, while the drilling phase generated comparable impacts. Estimates of economic impacts are greater in a dynamic spatial panel model that allows for spillover effects across local economies as well as over time. - Highlights: • Economic impacts and multiplier effects differ between oil and gas wells in Texas. • Interactions among local economies raise employment and income effects. • Impacts persist over time, raising the long-run multipliers. • Greater economic impacts from newly drilled wells than legacy wells.

Full Text Available The article is dedicated to risk assessment and analysis (RAA in oil and gas industry. The article reviews current trends of risks’ assessment and management in oil and gas industry in relation to the activities of enterprises engaged in engineering design in the field of oil and gas processing considering the requirements of international standards (ISO. The classification of risks is provided with consideration of peculiar features of enterprises of Mineral Resources Sector. The authors present a review of major international and national standards, specifying the activities in risk management. It is shown that one of the modern trends of international standardization is a development of risk management and management of sustainable business based on the risk oriented approach. The authors have proposed the algorithm of risk management in oil and gas projects using the domestic software Business Studio, logically divided into following three stages: identification and assessment of project risks, development of risks mitigation measures and monitoring of project risks. The main indicators of the oil and gas complex of Russia (the volume of oil and gas, the primary oil refining, are the main risk factors for the oil and gas industry. The peculiarities of risk management are described in the form of an economic category. The article shows that risk can and should be controlled, in other words, certain measures should be applied to anticipate as many as possible the risk events and to reduce them.

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.
