This study provides insight into the feasibility of a CO2 trunkline from the Netherlands to the Utsira formation in the Norwegian part of the North Sea, which is a large geological storage reservoir for CO2. The feasibility is investigated in competition with CO2 storage in onshore and near-offshore sinks in the Netherlands. Least-cost modelling with a MARKAL model in combination with ArcGIS was used to assess the cost-effectiveness of the trunkline as part of a Dutch greenhouse gas emission reduction strategy for the Dutch electricity sector and CO2 intensive industry. The results show that under the condition that a CO2 permit price increases from 25 euro per tCO2 in 2010 to 60 euro per tCO2 in 2030, and remains at this level up to 2050, CO2 emissions in the Netherlands could reduce with 67% in 2050 compared to 1990, and investment in the Utsira trunkline may be cost-effective from 2020-2030 provided that Belgian and German CO2 is transported and stored via the Netherlands as well. In this case, by 2050 more than 2.1 GtCO2 would have been transported from the Netherlands to the Utsira formation. However, if the Utsira trunkline is not used for transportation of CO2 from Belgium and Germany, it may become cost-effective 10 years later, and less than 1.3 GtCO2 from the Netherlands would have been stored in the Utsira formation by 2050. On the short term, CO2 storage in Dutch fields appears more cost-effective than in the Utsira formation, but as yet there are major uncertainties related to the timing and effective exploitation of the Dutch offshore storage opportunities.

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

Gas Transport Services. West European Gas Transmission Tariff Comparisons

International Nuclear Information System (INIS)

2006-07-01

Since 1999, the Dutch gas transmission company, Gastransport Services (GTS), has commissioned an independent consultant to prepare reports comparing gas transportation tariffs across Western Europe on an annual basis. This report describes the tariffs in force at 1 February 2006. The previous report was published in May 2005, and reported on the tariffs which were in force at 1 January 2005. Since then several companies have published revised carriage arrangements, or have adjusted their tariffs (e.g. to reflect inflation, or for other reasons). In this report we compare the GTS tariff with the transportation tariffs in eleven other countries: Austria, Belgium, Denmark, France, Germany, Ireland, Italy, Luxembourg, Spain, Sweden, and the United Kingdom. This means that all West European countries with Third Party Access to gas transmission systems (except Finland) are covered in this report. In this main part of the report, we concentrate on showing charts which illustrate the comparisons of tariffs, at various distances, volumes and load factors. This gives an overall picture of the tariffs offered by each company, rather than concentrating on particular cases. The detailed calculations for each of the 45 cases are shown in the Appendix to this report, and the conclusions from the cases are shown in a colour-coded chart in the Summary and Conclusions.

Full Text Available Gas service station workers who work near volatile organic compounds (VOCs sources, such as gasoline vapor emissions, and motor vehicle exhausts, may be exposed to highly elevated VOCs levels. This study investigates air samples from gas service stations in Thailand to evaluate the health risks following inhalation exposure. Personal air samplings were obtained at nine gas service stations in Chonburi, Thailand from October to December 2007. The concentrations of benzene, toluene, ethylbenzene, xylenes, and hexane in the air from the workplaces were significantly higher than in a control group of office workers (p<0.05. However, all VOCs in these air samples were lower than TWA limit of Thailand and the OSHA standard. Samples of urine, collected after 8-h work periods which were analyzed for VOCs metabolites, including t,t muconic acid, hippuric acid, mandelic acid and m-hippuric acid, demonstrate that the average levels of metabolites in gas service station workers and in controls were close, except for t,t muconic acid of gas service station workers which displayed higher levels than the in the controls. The lifetime cancer and noncancer risks for the workers exposed to VOCs were also assessed. Results show that all nine gas service stations in this study had a elevated lifetime cancer risk ranging from 53 to 630 per million, thus exceeding the normal risk of 1 per million. For noncancer risks, the levels in all gas stations ranged between 0.03 and 0.4, which is well below the reference hazard level of 1.0. Benzene may the most important cause of both cancer and noncancer risk followed by 1,3 butadiene.

Highlights: • Gas turbine blades operated in-service have been investigated. • Two primary MC decomposition reactions take place during servicing. • Deformation features during servicing have been analyzed. - Abstract: The nickel based superalloy GH4037 is employed in gas turbine blades because of its high temperature strength and oxidation resistance. Microstructural evolution and deformation features in gas turbine blades after 1600 h service have been investigated by Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). The microstructure of blade changes according to complex and comprehensive temperature and stress fields applied on it. Microstructural observations show that minor carbide precipitates dispersedly precipitate in the matrix. Two MC decomposition reactions occur: MC + γ → M{sub 23}C{sub 6} + γ′ and MC + γ → M{sub 23}C{sub 6} + η. Blocky, closely spaced M{sub 23}C{sub 6} particles continuously distribute along grain boundaries. The main deformation features, such as slip bands, APB-coupled dislocation pairs, stacking faults bound by partial dislocations and deformation twinning, have also been analyzed in terms of fundamental deformation mechanisms and environmental effects.

If all gas turbine components which are in contact with hot gas are manufactured from special ceramics (silicon nitride, silicon carbide), cycle and component temperatures can be increased up to 1600/sup 0/K. MTU is developing various components, such as combustor and turbine wheel, step by step until they are ready for service. At present, combustors are surviving comprehensive service-like cyclic tests in hot gas at atmospheric pressure (1000 h, 1000 starts per component) without damage. Tests above atmospheric pressure (5 bar) are underway. At MTU, a rotor wheel variant consisting of a metallic hub with inserted single blades is being constructed. The step to aerodynamically contoured airfoils will follow, as soon as the stress problems encountered in connection with the blade root are fully under control. The program will be completed in 1980 with a test run of a prototype turbine made from ceramic components developed by various companies under the leadership of the DFVLR (Aerospace Research and Testing Institute).

The oil and gas equipment and services market in India

International Nuclear Information System (INIS)

2002-01-01

In terms of purchasing power, India represents the fourth largest economy in the world. In the year April 1, 2001-Mar 31, 2002, it was estimated that India had a 5.4 per cent growth in gross domestic product (GDP). Canada experienced a 19.9 per cent increase in exports to India in 2001, reaching 656 million dollars. With the world's six-largest energy consumption, oil demand in India is expected to grow to 179 million tonnes in 2006-2007, while the demand for natural gas is expected to reach 231 million cubic metres per day in the same period. To meet this growing demand, India will require investments in the order of 150 billion dollars over the next 10 to 12 years. The oil and gas industry is being opened to the private sector and foreign direct investment, due to new government policies on exploration, production, distribution, and sales. Foreign involvement in exploration, previously restricted to Indian state-owned firms, is now allowed through the New Exploration Licensing Policy. In exploration and production (E and P) activities, as well as the refinery sector, foreign ownership of up to 100 per cent is now allowed. Two Indian companies which dominate the Indian E and P sector, namely Oil and Natural Gas Corporation (ONGC) and Oil India Limited (OIL), will be upgrading their ageing infrastructure, purchasing new equipment and redeveloping existing oil and gas fields, thereby creating opportunities for the supply of equipment and services. Canadian companies possessing the latest technologies and services in exploration, drilling machinery and equipment, directional drilling services, production machinery and equipment, enhanced recovery services, deep-water drilling equipment and services, and equipment for coal methane E and P should benefit from these opportunities. Over 12,000 kilometres of pipelines are being planned across India, as well as private opportunities in the refinery sector which was opened to the private sector in April 2002. Occasional

Gazi Mohammad Hasan Jamil

2014-08-01

Full Text Available Abstract. With the rising costs of gasoline, many vehicle owners are looking for alternatives of it. Compressed natural gas (CNG has been tested for this very purpose in some countries and found as a better alternative so far. CNG comes from country’s natural resources and it is clean and less costly to use. This paper is mainly an analysis of the potential benefits of using natural gas as a transportation fuel by the service delivery industries. It will examine CNG’s potential contribution in reducing delivery and vehicle maintenance cost, saving money in the long run projects, improving fuel efficiency, enhancing physical safety and assuring environment friendly emissions of carbon monoxide or reactive gases for the service delivery industries.Keywords: Compressed natural gas (CNG, Service Delivery, Fossil fuel, Global warming, Competitiveness

Report on the service quality incentive regulations for gas network operators and ERDF. 2009-2010 Report Synthesis

International Nuclear Information System (INIS)

2010-11-01

The latest natural gas transmission network tariffs, called 'ATRT4', and the tariffs for natural gas distribution network, 'ATRD3', as well as the 3. tariffs for using the public electricity networks, 'TURPE 3', constitute a regulatory framework offering incentives to gas transmission and distribution operators, as well as the electricity distributor ERDF, to control their costs and improve the quality of service provided for network users. For gas and electricity distribution system operators (DSO), the incentive-based regulation for quality of service implemented through the tariffs is complementary to the supervision powers of the licensing authorities. It operates by means of concession contracts which imply that the concessionaire has to deliver activity reports and that the licensing authorities have to publish monitoring reports of the concessionaire's activity. The licensing authorities act on the local level, whereas the incentive regulation is of national scope. The actions of the licensing authorities and of the Energy Regulatory Commission (CRE) contribute together to assess and enhance the quality of service of the DSO. As the service quality monitoring exercises are conducted successively, the analysis will become more refined as a greater data history is acquired. The quality of service from the gas network operators (GrDF, GRTgaz and TIGF) and the electricity distributor (ERDF) has been improving gradually over the period of the monitoring, or has stabilised at a satisfactory level for the areas that are most important for the correct functioning of the market. Some objectives set by the tariffs have been met or even exceeded, which earns financial bonuses for the operators in question. This second service quality monitoring report on the gas network operators and ERDF is going to be used by the CRE, in consultation with all the market players, to refine the incentive mechanisms already in place.

The state secretariat for industry has launched a large public debate between June and October 1999 based on a white book titled 'Towards the future organization of the gas sector'. The suggestions obtained were substantial. A brief presentation is added to the draft of the law devoted to revamping of natural gas supply public service and to development of gas enterprises. The presentation addresses the following points: 1. A public gas supply service modern and thought to reconcile the dynamism, equity and solidarity. 2. A controlled opening of the natural gas market towards competition: participating to the struggle for employment. 3. Tools ensuring the quality of gas supply and security of resources. 4. A transparent and efficient regulation: creating the conditions of a nondiscriminatory competition. 5. Requirements for developing the transport of natural gas regime. 6. Storage. 7. Social questions. The draft of the law relating to revamping of natural gas supply public service and to development of gas enterprises is a working document, not engaging the government. It is based on six titles. Title 1 and Title 2 treat the points 1 and 2 mentioned above. Title 3 contains two chapters devoted to transparency and accounting dissociation and to regulation in the natural gas sector, respectively. The Title 4 contains three chapters devoted to: 1. authorization of the works of natural gas transport; 2. gas distribution and 3. exploitation of the transport and natural gas distribution network. The fifth Title is dedicated to underground storage. The sixth Title presents diverse directives.

A banner year in southern Alberta : shallow gas, CBM drive service houses to record years

International Nuclear Information System (INIS)

Colbourne, C.

2005-01-01

The effect of increased oil and gas activity on the service and supply industry in Alberta was evaluated. The service and supply industry is benefiting from booms in shallow gas drilling and coalbed methane exploration. Big Country Energy Services is a pipeline installation company that now has over 40 on-going projects with crews ranging in size from 10 to 70 personnel. A shortage of skilled labour has affected the company's ability to meet demand. Manufacturing companies such as Production Control Services, a self-contained parts manufacturer that specializes in plunger lift service and optimizing and servicing gas wells, is also seeing an increase in business, particularly due to recent activity in the coalbed methane sector. The company services both new and existing wells in the region. Managers at Ronco Oilfield Hauling Ltd., who work with many junior companies, believe that this season will be one of the most successful of all time. It was suggested that an increase in energy demand from countries like China will keep the demand for North American oil high. However, trends have indicated a reduction in exploration in Alberta, while new exploration activity appears to be increasing in northern Canada. Officials at Ronco have predicted that in 10 to 15 years most new oil activity will be in the northern regions as well as in northeastern British Columbia. It was also noted that soaring fuel costs have had an impact on the service and supply industry, particularly in businesses responsible for collecting and disposing of drilling fluids from rigs. Companies specializing in gas well optimization in low-pressure situations have also benefited from increased activity. However, issues concerning under-qualified workers and personnel shortages have affected a wide variety of businesses in the industry. 3 figs

The oil and gas equipment and services market in Bolivia

International Nuclear Information System (INIS)

2003-01-01

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

Investigation of MTBE and aromatic compound concentrations at a gas service station.

Science.gov (United States)

Lin, Chi-Wen; Chiang, Song-Bor; Lu, San-Ju

2005-06-01

Methyl tert-butyl ether (MTBE) has been used as a fuel additive at levels of 2-11% in Taiwan for the past decade. The purpose of this additive is to enhance the octane, replace the use of lead-based anti-knock gasoline additives and reduce aromatic hydrocarbons. However, it is possible that oxygenated fuel has a potential health impact. To determine the air quality impact of MTBE, measurements were made of ambient MTBE and other gasoline constituents at a service station. Additionally, environmental conditions (wind speed, wind direction, and temperature, etc.) that could affect concentrations of emission constituents were measured. Gas samples were analyzed for target MTBE and volatile organic compounds, e.g., benzene and toluene. Ambient samples were collected using Tenax adsorbent tubes for mass spectrometric analysis at a service station located in Changhua County, Taiwan. The resulting measured ambient air concentrations were compared with Taiwan's regulatory standards for hazardous air pollutants. Subsequently, the factors controlling the formation of high-VOC levels at the service station and in the residential neighborhoods were identified. Additionally, the results can provide the Environmental Protection Agency (EPA) of Taiwan with useful information and prompt them to mandate this gas service station to install a refueling vapor recovery system.

The four-acre ecological restoration of tall grass prairie, wetland and Savannah ecosystems within the Union Gas Customer Service Centre in Brantford, Ontario is discussed. The restoration of the Brant Prairie site was instigated three years ago through Union Gas` land stewardship and environmental action initiative which tried to encourage the diversity and dynamics of each ecosystem, while creating a community resource for visitors to learn about natural heritage. The Brantford initiative includes: (1) protecting the sedge wetland which contained regionally rare species, (2) maintaining the dynamic water budget while protecting the sedge wetland from roadway contaminants, (3) creating a tall grass prairie similar in diversity and aesthetics to Brantford`s surviving prairie remnants, (4) creating a wildlife habitat for butterflies, birds and aquatic species, and (5) rediscovering partridge pea by uncovering a historic seed bank.

Gas storage services and regulation in Italy. A Delphi analysis

International Nuclear Information System (INIS)

Bonacina, Monica; Creti, Anna; Sileo, Antonio

2009-01-01

The objective of this paper is to assess to which extent gas market inefficiencies, such as weak competition, import dependence and lack of flexibility tools, affect operation and usage of storage services in Italy in the aftermath of the EU liberalization process. The analysis is supported by the empirical results of a Delphi survey that we have conducted to investigate storage service provision and regulation in Italy. We argue that the Italian storage sector is at a crossroads. The policy-driven phase of liberalization is ending and the market-driven phase has just begun. The former phase has granted fair access to storage, narrowed the likelihood of strategic behaviour by the incumbent and secured residential users against supply disruptions, but it has proved dynamically inefficient. Cost-reflective tariffs and low penalties for unbalances have both lowered incentives to expand the range of flexibility tools and penalized industrial customers demand. The market-driven phase has just started. The expected increase in working capacity and the entry of newcomers in the authorization process for new facilities are a progress towards the commercial use of storage. To this end, however, a further change in gas market design is needed: the creation of a well functioning spot market. (author)

Influence of coating quality on the service life of land-based gas turbine blades

Energy Technology Data Exchange (ETDEWEB)

Cheruvu, N.S. [Southwest Research Institute, San Antonio (United States)

2007-06-15

The land-based gas turbine blades operate at severe operating conditions: higher metal temperatures and stresses, and severe duty cycles. Metallic coatings with or without a top ceramic coating have been used to protect the turbine blades. The durability of the coating system is one of the prime life-limiting factors of modem gas turbine blades. The quality of the coating plays a critical role on the coating life. This paper discusses the failure mechanisms of the coatings and describes how the quality of the coating affects the service life of a gas turbine blade. A few case studies are presented in the paper. (orig.)

Report on the incentive regulation regarding the service quality of natural gas network operators and ERDF. Summary report 2011

International Nuclear Information System (INIS)

2012-05-01

The tariffs set by the French Energy Regulation Commission (CRE) for natural gas distribution system operators (DSOs), natural gas transmission system operators (TSOs) as well as for the electricity distribution system operator electricite Reseau Distribution France (ERDF) include an incentive regulation regarding the quality of service. The CRE has defined indicators to monitor the performance of operators in several fields considered relevant to assess the quality of service. Some of these indicators, considered to have specific importance in ensuring that the market operates properly, are subject to a system of financial incentives: bonuses or penalties are given to operators depending on the attainment of objectives set by the CRE. Other indicators, which do not carry financial incentives, complete the mechanism and ensure a broader surveillance of the operators' service quality. A financial incentive may be applied to these indicators at a later date if the CRE deems it necessary. The analyses of the service quality monitoring indicators presented in this report cover the period from 1 July 2010 to 30 June 2011. They were used to inform the work conducted to develop the incentive regulation mechanism for service quality in GrDF's ATRD4 tariff (A Third-party access to natural gas distribution networks, scheduled to enter into effect on 1 July 2012). The conclusions of the report will also be used by the CRE for ERDF as part of the work on TURPE 4 tariff (Tariff for the use of public electricity grids, scheduled to enter into effect during the third quarter of 2013), for natural gas local distribution companies (LDCs) to prepare their ATRD4 tariff (Entry into effect scheduled for 1 July 2013), as well as for GRTgaz and TIGF to define the future ATRT5 tariff (Third-party access to natural gas transmission networks, scheduled to enter into effect on 1 April 2013).

Turbine blade samples from three land based gas turbines have been subjected to systematic condition and life assessment after long term service (88000 - 109000 equivalent operating hours, eoh), when approaching the nominal or suggested life limits. The blades represent different machine types, materials and design generations, and uncooled blading outside the hottest front end of the turbine, i.e. blades with relatively large size and considerable expected life. For a reasonable assessment, a range of damage mechanisms need to be addressed and evaluated for the impact in the residual life. The results suggested significant additional safe life for all three blade sets. In some cases this could warrant yet another life cycle comparable to that of new blades, even after approaching the nominal end of life in terms of recommended equivalent operating hours. This is thought to be partly because of base load combined cycle operation and natural gas fuel, or modest operational loading if the design also accounted for more intensive cycling operation and more corrosive oil firing. In any case, long term life extension is only appropriate if not intervened by events of overloading, overheating or other sudden events such as foreign object damage (FOD), and if supported by the regular inspection and maintenance program to control in-service damage. Condition based assessment therefore remains an important part of the blade life management after the decision of accepted life extension. (orig.)

The changing roles of natural gas aggregators - a Pan-Alberta Gas perspective

International Nuclear Information System (INIS)

Field, D. L.

1999-01-01

Traditional roles played by the various forms of natural gas marketing entities (margin-marketers, aggregators, brokers) and the factors that influence a producer of natural gas to market its gas through one or more of these entities are the subject of this paper. The author also reviews current developments in the natural gas marketing industry, focusing on changes from the perspective of the gas aggregator.The most significant change has been the trend by aggregators to branch out to provide a broad range of services that meet the needs of individual producers including gas management services for non-pool gas supply, transportation management, fixed and indexed pricing for both pool and non-pool supply, market based pricing, financial services for producers, short-term sales arrangements and streaming specific supply sources to specific markets. As aggregators continue to move away from offering only the traditional aggregator services, the distinction between aggregators and margin-marketers and the services they provide is becoming less distinct. The principal differences that will remain will be the differences in corporate structures and the shareholders who share the costs and receive the benefits generated by business activities of the aggregator. Another difference that will continue to exist is that margin-marketers offer North American-based services whereas aggregators focus on marketing natural gas primarily in Western Canada

Report on the quality of service of the gas network operators GrDF, GRTgaz and TIGF. Report 2008-2009

International Nuclear Information System (INIS)

2009-11-01

CRE, the Energy Regulatory Commission, publishes the first annual report on the quality of service of the gas networks operators, GrDF, GRTgaz and TIGF. The monitoring of GrDF's quality of service covers a one-year period, from July 1, 2008 to June 30, 2009; that of GRTgaz and TIGF covers a 6-month period, from January 1, 2009 to June 30, 2009. The first finding of this report is that the three operators took the necessary measures in terms of tools and resources to implement the mechanisms required by the tariffs rules. Furthermore, almost all indicators are now monitored and published regularly by the gas networks operators. The whole picture is that the quality of service of GrDF, GRTgaz and TIGF progressively improved over the monitoring period in the most significant areas related to a proper functioning of the market. However, the objectives set by the tariffs rules were not all met. This led to financial penalties for the gas networks operators. During the tariff period, the tariff rules allow to revise the monitoring mechanism, as the tariffs in force provide the possibility to update the indicators. Consequently, and based on this first report, CRE will be working with the gas networks operators and the market players to improve the monitoring mechanism implemented, focusing more on the quality of services provided to end users

Current gas storage R and D programmes at Gas Research Institute

International Nuclear Information System (INIS)

Shikari, Y.A.

1990-01-01

The Gas Research Institute (GRI) is currently involved in the development of concepts aimed at an enhancement of natural gas service to the consumer. In order to maintain the attractiveness of the gas options to industrial consumers and to reinforce the ''value-in-use'' of natural gas to residential as well as commercial customers, it is essential to develop efficient, economical, and safe means of reducing the ''cost-of-service'', including that of natural gas storage in underground formations. Specifically, research and development (R and D) is needed to explore ways to better utilize existing storage fields and also to develop new storage facilities at minimum cost. GRI is currently sponsoring research projects aimed at controlling gas migration in underground gas storage reservoirs, reducing base (or cushion) gas requirements, understanding the gas-gas phase mixing behaviour via laboratory experiments and reservoir models, developing cost-effective gas separation processes using membranes, and optimizing the operation and maintenance (O and M) costs of underground gas storage operations. This paper provides an overview of the GRI's Gas Storage R and D Programme and highlights key results achieved to date for selected research projects. (author). 16 refs, 6 figs, 3 tabs

Incentive regulation regarding the service quality of electricity and natural gas network operators in 2015. Follow-up Report, January 2017

International Nuclear Information System (INIS)

2017-01-01

The tariffs set by the French Energy Regulation Commission (CRE) for natural gas distribution system operators (DSOs), natural gas transmission system operators (TSOs) as well as for the electricity distribution system operator (Enedis, former ERDF) include an incentive regulation regarding the quality of service. The CRE has defined indicators to monitor the performance of operators in several fields considered relevant to assess the quality of service. Some of these indicators, considered to have specific importance in ensuring that the market operates properly, are subject to a system of financial incentives: bonuses or penalties are given to operators depending on the attainment of objectives set by the CRE. Other indicators, which do not carry financial incentives, complete the mechanism and ensure a broader surveillance of the operators' service quality. A financial incentive may be applied to these indicators at a later date if the CRE deems it necessary. The analyses of the service quality monitoring indicators presented in this report cover the period from January 1 to December 31, 2015. A review of the service quality of DSOs, TSOs and Enedis is made according to these indicators. An annex contains all individual quality reports of Enedis, DSOs and TSOs

Analyzing the Effects of Car Sharing Services on the Reduction of Greenhouse Gas (GHG Emissions

Directory of Open Access Journals (Sweden)

Jiyeon Jung

2018-02-01

Full Text Available This study examines the environmental impacts of roundtrip car sharing services by investigating transportation behavior. Car sharing should contribute to reduced greenhouse gas GHG emissions; however, such schemes include both positive and negative environmental effects, including: (1 reduced CO2e (carbon dioxide equivalent from substituting private vehicle use for more fuel-efficient car sharing vehicles, (2 increased CO2e as car-less individuals switch from public transit to car sharing vehicles and (3 reduced CO2e due to fewer vehicles. This study examines the impacts of this modal shift on greenhouse gas (GHG emissions using three types of models: a mixed logit model to analyze car sharing service preferences; a binary logit model to analyze whether individuals are willing to forgo vehicle ownership or planned purchases to use car sharing services; and a linear regression to determine how much private vehicle or public transportation use would be replaced by car sharing and the resulting effects on mobility. Total emissions from the current car sharing market equal 1,025,589.36 t CO2e/year. However, an increase in electric vehicle (EV charging stations to 50% of the number of gasoline-fuel stations would increase the probability of electric car sharing vehicle use, thereby reducing emissions by 655,773 t CO2e. This study shows that forgoing vehicle purchases does not offset the increased GHG emissions caused by the shift from public transportation or private vehicle use to car sharing.

Mitchell firmly retrenched in natural gas services

International Nuclear Information System (INIS)

Share, J.

1997-01-01

The past three years, Mitchell Energy and Development Corp. has undergone a massive restructuring that has changed the face of one of the nation's largest and best-known natural gas/natural gas liquids companies. Facing a rapidly changing industry that frequently has been stung by volatile swings in energy markets, management of the independent company, founded by George Mitchell in 1946, sold off $300 million in non-core assets; reduced its long-term debt by $400 million; instituted a hiring freeze and reduced its workforce by a third, from 2,900 to 1,950, over the last three years. Mitchell negotiated a buyout of its hugely profitable North Texas gas sales contract with Natural Gas Pipeline Company of America as a means of easing its transition to a market-sensitive price environment and reducing its debt. Mitchell also took operational control. Finally, Mitchell has left the real estate business, culminating July 31 with the sale of its real estate subsidiary, The Woodlands Corporation, for $543 million ($460 million net after-tax), further reducing its workforce to 1,100. On Aug. 18, the company said it will use the proceeds to repurchase common stock, retire another $200 million of public debt, make asset niche energy acquisitions and increase capital spending for existing programs. The result is a renewed focus on its exploration and production and gas gathering, processing and marketing businesses

A Comparison of the Impacts of Wind Energy and Unconventional Gas Development on Land-use and Ecosystem Services: An Example from the Anadarko Basin of Oklahoma, USA.

The United States energy industry is transforming with the rapid development of alternative energy sources and technological advancements in fossil fuels. Two major changes include the growth of wind turbines and unconventional oil and gas. We measured land-use impacts and associated ecosystem services costs of unconventional gas and wind energy development within the Anadarko Basin of the Oklahoma Woodford Shale, an area that has experienced large increases in both energy sectors. Unconventional gas wells developed three times as much land compared to wind turbines (on a per unit basis), resulting in higher ecosystem services costs for gas. Gas wells had higher impacts on intensive agricultural lands (i.e., row crops) compared to wind turbines that had higher impacts on natural grasslands/pastures. Because wind turbines produced on average less energy compared to gas wells, the average land-use-related ecosystem cost per gigajoule of energy produced was almost the same. Our results demonstrate that both unconventional gas and wind energy have substantial impacts on land use, which likely affect wildlife populations and land-use-related ecosystem services. Although wind energy does not have the associated greenhouse gas emissions, we suggest that the direct impacts on ecosystems in terms of land use are similar to unconventional fossil fuels. Considering the expected rapid global expansion of these two forms of energy production, many ecosystems are likely to be at risk.

Gas market distorting effects of imbalanced gas balancing rules: Inefficient regulation of pipeline flexibility

International Nuclear Information System (INIS)

Keyaerts, Nico; Hallack, Michelle; Glachant, Jean-Michel; D'haeseleer, William

2011-01-01

This paper analyzes the value and cost of line-pack flexibility in liberalized gas markets through examination of the techno-economic characteristics of gas transport pipelines and the trade-offs between different ways to use the infrastructure: transport and flexibility. Line-pack flexibility is becoming increasingly important as a tool to balance gas supply and demand over different periods. In the European liberalized market context, a monopolist unbundled network operator offers regulated transport services and flexibility (balancing) services according to the network code and balancing rules. Therefore, gas policy makers should understand the role and consequences of line-pack regulation. The analysis shows that the line-pack flexibility service has an important economic value for the shippers and the TSO. Furthermore, the analysis identifies distorting effects in the gas market due to inadequate regulation of line-pack flexibility: by disregarding the sunk costs of flexibility in the balancing rules, the overall efficiency of the gas system is decreased. Finally, the analysis demonstrates that the actual costs of line-pack flexibility are related to the peak cumulative imbalance throughout the balancing period. Any price for pipeline flexibility should, therefore, be based on the related trade-off between the right to use the line-pack flexibility and the provision of transport services. - Research Highlights: →Line-pack flexibility is a main gas balancing instrument. →Capacity related costs of line-pack flexibility depend on peak cumulative imbalances. →Line-pack pricing rules determine choice between ex ante and ex post balancing. →Inefficient line-pack regulation causes gas market distortions.

Restructuring local distribution services: Possibilities and limitations

Energy Technology Data Exchange (ETDEWEB)

Duann, D.J.

1994-08-01

The restructuring of local distribution services is now the focus of the natural gas industry. It is the last major step in the ``reconstitution`` of the natural gas industry and a critical clement in realizing the full benefits of regulatory and market reforms that already have taken place in the wellhead and interstate markets. It could also be the most important regulatory initiative for most end-use customers because they are affected directly by the costs and reliability of distribution services. Several factors contribute to the current emphasis on distribution service restructuring. They include the unbundling and restructuring of upstream markets, a realization of the limitations of supply-side options (such as gas procurement oversight), and the increased diversity and volatility of gas demand facing local distribution companies. Local distribution service is not one but a series of activities that start with commodity gas procurement and extend to transportation, load balancing, storage, and metering and billing of services provided. There are also considerable differences in the economies of scale and scope associated with these various activities. Thus, a mixture of supply arrangements (such as a competitive market or a monopoly) is required for the most efficient delivery of local distribution services. A distinction must be made between the supply of commodity gas and the provision of a bundled distribution service. This distinction and identification of the best supply arrangements for various distribution service components are the most critical factors in developing appropriate restructuring policies. For most state public utility commissions the criteria for service restructuring should include pursuing the economies of scale and scope in gas distribution, differentiating and matching gas service reliability and quality with customer requirements, and controlling costs associated with the search, negotiation, and contracting of gas services.

Developing the east coast gas industry

International Nuclear Information System (INIS)

Stedman, C.

1998-01-01

Development of a natural gas industry on Canada's east coast was discussed. The various stages of near-term and long-term development were outlined. Opportunities were identified in the areas of Grand Banks gas utilization, third party gas and natural gas liquids transportation and processing, cogeneration, petrochemicals and in energy marketing and services. As an example of this industry development, a corporate review of Novagas Canada Ltd., was presented. The company was formed in January 1994 and is wholly owned by Nova Gas International. Novagas Canada has ultimate resources of 62.9 Tcf of natural gas of which 48.9 Tcf remains to be discovered. The company focuses on non-regulated mid-stream operations of the natural gas/natural gas liquid value chain. Some 800 million dollars have been invested so far in gas processing, liquids and olefins businesses in Nova Scotia and the Grand Banks/Labrador area. The pending Nova/TCPL merger will combine Novagas Canada's and TransCanada Gas Services' midstream assets. The general conclusion was that the resource base is large enough to support development throughout the gas and natural gas liquids value chain, and that a critical mass is required to support development of the necessary gas infrastructure. A sizeable challenge remains in encouraging gas utilization, and in encouraging competition, open access and unbundling of energy services. 2 tabs., 2 figs

Productivity improvements in gas distribution

Young, M.R.

1997-01-01

In 1993, the Hilmer Report resulted in the introduction of the National Competition Policy which, in the case of the gas industry, aims to promote gas-on-gas competition where to date it has been excluded. In response, and to prepare for wide gas industry reform, Gas and Fuel formed three fundamentally different core businesses on 1 July 1996 - Energy Retail, Network, and Contestable Services. In one productivity improvement initiative which is believed to be unique, Gas and Fuel appointed three companies as strategic alliance partners for distribution system maintenance. Gas and Fuel can now concentrate on its core role as asset manager which owns and operates the distribution system while procuring all services from what will become non-regulated businesses. This Paper details this initiative and the benefits which have resulted from overall changes and improvements, and outlines the challenges facing Gas and Fuel in the future. (au)

Internet traffic has grown rapidly in recent years and is expected to continue to expand significantly over the next decade. Consequently, the resulting greenhouse gas (GHG) emissions of telecommunications service-supporting infrastructures have become an important issue. In this study, we develop a set of models for assessing the use-phase power consumption and carbon dioxide emissions of telecom network services to help telecom providers gain a better understanding of the GHG emissions associated with the energy required for their networks and services. Due to the fact that measuring the power consumption and traffic in a telecom network is a challenging task, these models utilize different granularities of available network information. As the granularity of the network measurement information decreases, the corresponding models have the potential to produce larger estimation errors. Therefore, we examine the accuracy of these models under various network scenarios using two approaches: (i) a sensitivity analysis through simulations and (ii) a case study of a deployed network. Both approaches show that the accuracy of the models depends on the network size, the total amount of network service traffic (i.e., for the service under assessment), and the number of network nodes used to process the service.

This work approaches the issue of developing the national goods and services market for the natural gas area, analyzing the constraints that exist today to the growth of the supply of goods and services and proposes innovative strategies and actions to accelerate the emergence of this supply. The suggested strategies and actions are presented in the form of two management models: the first aimed towards the development of pioneering equipment and the other directed to augmenting the supply of services within the country, focusing on human training programs, technological assistance to companies and the development of applied research projects. The models may be adopted by a company that intends to assume the leadership in the commercialization of natural gas, offering its clients not only a commodity but an energy solution. The innovation strategies applicable to each model are analyzed, discussing the advantages in the adoption of each one by the natural gas industry. The social profits resulting from the proposed actions and the general results expected from the adoption of the two models are presented focusing the contribution to foster the share of natural gas in the Brazilian Energy Matrix.

Market demand for natural gas in Canada's Maritime provinces was discussed. The Atlantic market represents the largest potential region, currently without access to natural gas in Canada or the United States. Maritimes and Northeast Pipelines and the Sable Offshore Energy partners have made great efforts to introduce and market natural gas as well as to provide pipeline transportation services in the Maritimes and New England markets. Maritimes and Northeast Pipelines is a partnership project with Westcoast Energy, Mobil Oil, and Duke Energy. Theirs is the first pipeline project to deliver gas, but it will certainly not be the last gas project in the region. Maritimes and Northeast Pipelines now has 180,000 MMBtu/day of phased-in Canadian load committed to firm service agreements for delivery in the first 24 months of operation. In addition to these firm service agreements, an additional 60,000 MMBtu/day is signed for future lateral extensions to service emerging markets. figs

Natural gas deregulation: have the handcuffs really been removed?

Kelley, T.D.

1995-01-01

The natural gas market in New York State was reviewed and characterized as being very competitive. A brief description of the New York State Electric and Gas Corp. (NYSEG) was given. As regards recent developments, in October 1993, the New York Public Service Commission (NYPSC) instituted a proceeding (93-G-0932) on the restructuring of the gas market. Several guidelines for market restructuring were established as a result. The guidelines were in respect to service to consumers, safety of distribution, environmental implications, consumer concerns, gas rates, regulation, and access for core customers. The speaker noted that these guidelines did not promote deregulation. Competitive issues faced by local gas distributors were enumerated. Among these were (1)service to core and non-core customers (2)transition costs, (3)streaming, (4)unbundling and repackaged services, (5)price differentiation, and (6)small customer aggregation. It was expected that marketers would oppose the Public Service Commission giving local gas distributors additional pricing flexibility

Benefits of real-time gas management

Nolty, R.; Dolezalek, D. Jr.

1994-01-01

In today's competitive gas gathering, processing, storage and transportation business environment, the requirements to do business are continually changing. These changes arise from government regulations such as the amendments to the Clean Air Act concerning the environment and FERC Order 636 concerning business practices. Other changes are due to advances in technology such as electronic flow measurement (EFM) and real-time communications capabilities within the gas industry. Gas gathering, processing, storage and transportation companies must be flexible in adapting to these changes to remain competitive. These dynamic requirements can be met with an open, real-time gas management computer information system. Such a system provides flexible services with a variety of software applications. Allocations, nominations management and gas dispatching are examples of applications that are provided on a real-time basis. By providing real-time services, the gas management system enables operations personnel to make timely adjustments within the current accounting period. Benefits realized from implementing a real-time gas management system include reduced unaccountable gas, reduced imbalance penalties, reduced regulatory violations, improved facility operations and better service to customers. These benefits give a company the competitive edge. This article discusses the applications provided, the benefits from implementing a real-time gas management system, and the definition of such a system

The Roaring Fork Transit Authority (RFTA) and its VelociRFTA Bus Rapid Transit (BRT) program are unique in many ways. For example, VelociRFTA was the first rural BRT system in the United States and the operational environment of the VelociRFTA BRT is one of the most severe in the country, with extreme winter temperatures and altitudes close to 8,000 feet. RFTA viewed high altitude operation as the most challenging characteristic when it began considering the use of natural gas. RFTA is the second-largest public transit system in Colorado behind Denver's Regional Transportation District (RTD), and it is one of the largest rural public transit systems in the country. In 2013, RFTA accepted delivery of 22 new compressed natural gas (CNG) buses that went into service after completion of maintenance and refueling facilities earlier that year. This paper examines the lessons learned from RFTA's experience of investigating--and ultimately choosing--CNG for their new BRT program and focuses on the unique environment of RFTA's BRT application; the decision process to include CNG fueling in the project; unforeseen difficulties encountered in the operation of CNG buses; public perception; cost comparison to competing fuels; and considerations for indoor fueling facilities and project funding.

Transportadora Brasileira Gasoduto Bolivia-Brazil S.A. - TBG, In order to perform with efficiency and quality, has always been committed to providing its customers with the best services and support. This commitment has been materialized with the recent implementation of a state-of-the-art technology that allows TBG to automatically manage all of its requests for services and to guarantee the delivery of gas to its customers is done in a safe way, optimizing pipeline capacity. To offer these levels of service, it was necessary to acquire a field proven solution capable of managing all commercial procedures as well as providing the right tools to operation to evaluate the capacity to move gas throughout the pipeline. Therefore the solution also was required to be easily integrated with existing operational and commercial tools such as the SCADA system and SAP R3 software. Reductions of fuel consumption and mitigation of risks against contractual penalties are some of the benefits reached. (author)

The transition to open-access storage in U.S. natural gas markets

International Nuclear Information System (INIS)

Schell, L.S.; Schlesinger, B.

1990-01-01

In their traditional role as merchants, interstate natural gas pipelines in the U.S. sold natural gas at an aggregate price that incorporated all gathering, storage, transmission, and gas costs in a bundled service. As a result of movements toward deregulation, U.S. gas users now enjoy open-access transportation on most interstate pipeline systems as an unbundled service at a relatively unbundled price, allowing them to contract for their own gas supplies, separate and apart from the system sales gas of traditional pipeline supplier(s). Open-access storage has been slower than open-access transportation service in evolving; its limited availability is a major factor limiting the comparability of service between transportation gas and system sales gas. Open access to storage offers gas users an important tool in managing gas costs, timing of gas purchases, and deliverability imbalances

Evaluation of Public Service Electric & Gas Company`s standard offer program, Volume I

Goldman, C.A.; Kito, M.S.; Moezzi, M.M.

1995-07-01

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

With the object of responding to the progressive increase in the demand for air-conditioning in the domestic sector with the presentation of gas as a competitive alternative to the electric systems currently available, and in order to avoid not only the loss of this specific market but also of the heating and hot water markets in the new-build residential sector, a new individualized energy selling service has been developed. This new option incorporates the advantages of the individualized and centralized systems of air-conditioning thanks to the utilisation of the medium-size gas air-conditioning systems currently available and to the geNie system as an instrument for totally individualizing the service and offering truly innovative features that will be attractive to the consumer. This new line of activity, implemented by the Serviconfort, a subsidiary company off the Gas Natural Group, has proven its viability both in technological and in service-definition terms in a series of demonstrations with more than 800 clients, which have served to indicate the considerable interest of the new-build residential sector in Spain and the expectations for the potential market over the next few years.

Corporate renewal in the natural gas industry

International Nuclear Information System (INIS)

Simpson, B.

1994-01-01

The changes occurring at the gas-related operating companies of Nova Corporation of Alberta are reviewed. These companies include Nova Gas Transmission, Alberta's major gas pipeline company, which moved 3.8 trillion ft 3 of gas in 1993; Nova Gas Services, a provider of gas management services to customers in Canada, USA, and Mexico; and Novacorp International, a joint venture investor in gas pipeline developments and consulting. The changes were made in response to increased competition in the gas transport industry following the deregulation process that started in the mid-1980s. A strategic direction based on growth rather than cost-cutting was chosen in order to make the Nova companies dominant players in North American gas supply. Nova's confidence in being able to implement such a strategy is based on four factors: abundant supply of gas and high potential for growth in the Western Canada Sedimentary Basin; steadily growing demand for gas; the development of a market-responsive industry; and the emergence of a truly North American market that includes Mexico. Business transformation teams were established with the task of finding out the right business design to meet customer needs and to provide exceptional service. Detailed plans for implementing the transformation are being completed, and a performance measurement system with clear targets has been developed to measure the success of the transformation

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

In these past few years, natural gas in Brazil has arised as one of the alternatives for the energetic crisis suffered by the country. Such situation was one of the motives for its expansion, rising, after that, the importance of the regulation of its distribution. The regulation of canalized natural gas distribution can be found in the Federal Constitution, after Constitutional Amendment n. 05/95, in the article n. 25, para. 2nd, which say that belongs to the Federal States the concession or direct exercise of canalized natural gas services, now clearly classified as a public service. In order of these events, its imperative the analysis of natural gas distribution's public service, because it belongs to the Federal States. According to this situation, the study of the new regulatory function of the Administration and the tracing of action for the regulatory state agencies are the main goals of this work. As so, the present research aims to focus the reflexes from the actual dimension of natural gas distribution, specially referring to its regulatory statements, the limitations of state agencies, the National Petroleum Agency and the market where distribution belongs, and particularly the open access of new agents.

Accounting for gas in a de-regulated environment

International Nuclear Information System (INIS)

Zawalykut, P.M.

1992-01-01

Since the natural gas industry was deregulated, the method of buying, selling and moving gas has changed significantly. Post-deregulation, the pipeline company moves the gas but does not acquire ownership. The full impact of deregulation is seen in opening up the market for buying and selling gas. Tracking of gas has become critical. The service customer is now buying and moving gas. The end-use customer nominates to the distribution company a quantity of gas to be transported. Responsibility is placed on the customer to estimate loads as accurately as possible to avoid possible charges. The distribution company passes the end-user nomination to the upstream transmission company, which in turn passes it along, a process that is repeated until the nomination reaches the production company. Authorizations for gas follow a similar path. The major difference between sales and service gas is the accounting and tracking. As the customer will not consume the exact amount nominated, there will be an imblance between what was nominated and metered. There will also be imbalances between what the producer places into the pipeline and what was nominated. These processes can cause administrative problems, and many customers are moving from sales to service

Marketing San Juan Basin gas

International Nuclear Information System (INIS)

Posner, D.M.

1988-01-01

Marketing natural gas produced in the San Juan Basin of New Mexico and Colorado principally involves four gas pipeline companies with significant facilities in the basin. The system capacity, transportation rates, regulatory status, and market access of each of these companies is evaluated. Because of excess gas supplies available to these pipeline companies, producers can expect improved take levels and prices by selling gas directly to end users and utilities as opposed to selling gas to the pipelines for system supply. The complexities of transporting gas today suggest that the services of an independent gas marketing company may be beneficial to smaller producers with gas supplies in the San Juan Basin

Gas marketing: Does size equal survival?

1996-01-01

The thought is enough to make many homeowners cringe: competing natural gas marketers calling them at home in the evening, pushing their brands and services much like AT and T, MCI and Sprint hawk long-distance telephone service today. Another thought is enough to make many gas marketers cringe: a half-dozen or fewer giant mega-marketers selling virtually all the natural gas in the US, and they and their company are not among them. Yet both thoughts are likely to become realities, say many in the natural gas industry. If so, each would represent an intriguing turn of events for the newest segment of the industry, one that barely existed 10 or 15 years ago. The paper discusses the recent history of the gas marketing sector, the changes taking place in the industry, and the biggest problem--the lack of a uniform electronic standard or bulletin board system for dispatching, nominating, and monitoring gas purchase as they move across the country

Effect of long time service exposure on microstructure and mechanical properties of gas turbine vanes made of IN939 alloy

Highlights: • Microstructure of service-exposed turbine vanes made of IN939 was investigated. • Mechanical properties of service-exposed alloy were also investigated. • Formation of M 23 C 6 films on GBs and degeneration of MCs are microstructural changes. • Despite its thermodynamic favorability, σ phase is not observed in microstructure. • Microstructural changes lead to a loss in tensile ductility and creep life. - Abstract: In the present study, the effects of long-term service exposure have been investigated on microstructure and mechanical properties of gas turbine vanes made of IN939 superalloy. The major microstructural changes for the investigated service-exposed vanes include the formation of continuous grain boundary carbides and the transformation (degeneration) of MC carbides located at the grain boundaries. The brittle σ phase, which is predicted to be stable on the basis of thermodynamic calculations, is not observed in the microstructure of service-exposed vanes. The microstructural changes during service lead to a loss in room temperature ductility as well as in creep properties of the alloy

2000-01-01

Following the UK Government's initiative for stimulating renewable energy through the Non-Fossil Fuel Obligation (NFFO), the UK landfill gas industry has more than trebled in size in just 4 years. As a result, UK companies are now in a strong position to offer their skills and services overseas. Ireland, Greece and Spain also resort heavily to disposal to landfill. Particularly rapid growth of the landfill gas market is expected in the OECD-Pacific and NAFTA areas. The article explains that landfill gas is a methane-rich mixture produced by anaerobic decomposition of organic wastes in landfills: under optimum conditions, up to 500 cubic meters of gas can be obtained from 1 tonne of biodegradable waste. Data on the number and capacity of sites in the UK are given. The Landfill Gas Association runs courses to counteract the skills shortage in the UK, and tailored courses for overseas visitors are planned

This study examines the regulation of natural gas in Brazil: It is limited to the legal conflict due to the constitution of the republic which determines the distribution of competence between the Federal Government and the States. It introduces the controversy about the limits conferred on the Government by the constitutional law of 1988, related to the transport of natural gas by pipeline, in contrast to the power of states to exploit the services of gas by pipeline. It analyzes the operation of Project Gemini originated by the movement of gas by PETROBRAS in Sao Paulo, without the intervention of the state. The legal opinion favourable to the state argues that the term 'gas delivery services' according to the Brazilian Law leads to the understanding that the use of plural covers all services of gas flowing, without any limitation on the purpose, is a flexible destination (home, companies), or the type of the user.

GAS STORAGE TECHNOLOGY CONSORTIUM

Energy Technology Data Exchange (ETDEWEB)

Robert W. Watson

2004-10-18

Gas storage is a critical element in the natural gas industry. Producers, transmission and distribution companies, marketers, and end users all benefit directly from the load balancing function of storage. The unbundling process has fundamentally changed the way storage is used and valued. As an unbundled service, the value of storage is being recovered at rates that reflect its value. Moreover, the marketplace has differentiated between various types of storage services, and has increasingly rewarded flexibility, safety, and reliability. The size of the natural gas market has increased and is projected to continue to increase towards 30 trillion cubic feet (TCF) over the next 10 to 15 years. Much of this increase is projected to come from electric generation, particularly peaking units. Gas storage, particularly the flexible services that are most suited to electric loads, is critical in meeting the needs of these new markets. In order to address the gas storage needs of the natural gas industry, an industry-driven consortium was created--the Gas Storage Technology Consortium (GSTC). The objective of the GSTC is to provide a means to accomplish industry-driven research and development designed to enhance operational flexibility and deliverability of the Nation's gas storage system, and provide a cost effective, safe, and reliable supply of natural gas to meet domestic demand. To accomplish this objective, the project is divided into three phases that are managed and directed by the GSTC Coordinator. The first phase, Phase 1A, was initiated on September 30, 2003, and was completed on March 31, 2004. Phase 1A of the project included the creation of the GSTC structure, development and refinement of a technical approach (work plan) for deliverability enhancement and reservoir management. This report deals with Phase 1B and encompasses the period July 1, 2004, through September 30, 2004. During this time period there were three main activities. First was the

Natural gas contracts in efficient portfolios

Energy Technology Data Exchange (ETDEWEB)

Sutherland, R.J.

This report addresses the {open_quotes}contracts portfolio{close_quotes} issue of natural gas contracts in support of the Domestic Natural Gas and Oil Initiative (DGOI) published by the U.S. Department of Energy in 1994. The analysis is a result of a collaborative effort with the Public Service Commission of the State of Maryland to consider {open_quotes}reforms that enhance the industry`s competitiveness{close_quotes}. The initial focus of our collaborative effort was on gas purchasing and contract portfolios; however, it became apparent that efficient contracting to purchase and use gas requires a broader consideration of regulatory reform. Efficient portfolios are obtained when the holder of the portfolio is affected by and is responsible for the performance of the portfolio. Natural gas distribution companies may prefer a diversity of contracts, but the efficient use of gas requires that the local distribution company be held accountable for its own purchases. Ultimate customers are affected by their own portfolios, which they manage efficiently by making their own choices. The objectives of the DGOI, particularly the efficient use of gas, can be achieved when customers have access to suppliers of gas and energy services under an improved regulatory framework. The evolution of the natural gas market during the last 15 years is described to account for the changing preferences toward gas contracts. Long-term contracts for natural gas were prevalent before the early 1980s, primarily because gas producers had few options other than to sell to a single pipeline company, and this pipeline company, in turn, was the only seller to a gas distribution company.

Electricity/natural gas competition in Quebec

Bernard, J.-T.

1992-01-01

The evolution of energy market shares (electricity, natural gas and oil products) in Quebec's residential and commercial sectors in the 1980s shows that energy source relative prices have influenced consumer behavior as expected. A set of comparisons from space and water heating markets in these sectors with regard to prices paid by consumers and costs incurred by society in general is presented. For the residential sector, it is seen that consumers pay only a fraction of the cost for electric space and water heating; the same service could be provided at smaller cost by natural gas. For the commercial sector, the electricity and natural gas tariffs convey the appropriate message with respect to the cost incurred in providing the service. 6 refs., 7 tabs

Due to the rapid development of the information technology, ageing is not the only driving force for replacing old computer systems with more sophisticated ones. The Finnish natural Gas company, Gasum Oy, has recently taken into use a new control and monitoring system for natural gas pipeline. A special customer service system, developed by Gasum Oy, is closely connected to monitoring system. It provides up-to-date information to all customers of Gasum Oy. The information is layered in three confidential levels: general information, operational data and invoicing information. The system is operating interactively in confidential Extranet. Inside Gasum Oy to meet the needs of departments outside the control room, a new GID system is developed. GID is a way to present pipeline process data and its further modifications with a very user-friendly interface based on geographical map. The system is based on data warehouse architecture and it is working on company's Intranet. This makes it possible to present various secrecy level information based on user ID. Gasum's new SCADA is not only the base for operating the pipeline, but it also provides lot of vital information to other systems serving different user groups within natural gas business in Finland.

Seo, J.K. [Korea Energy Economics Institute, Euiwang (Korea)

2001-12-01

This report explores controversial issues and problems that could emerge in the process of implementing the government's restructuring plan for natural gas industry and aims to suggest policy directions regarding the restructuring. To begin with, it examines current conditions surrounding natural gas industry including domestic demand and supply conditions, world LNG market trend, structural changes of the industry in OECD countries, possibilities of introducing effective competition and assignment of existing import contracts. In doing so, we probe whether the direction of the natural gas industry restructuring is proper and suggest that the results be reflected when a more detailed restructuring implementation plan is formulated. Also, this report suggests possible schemes related to major institutional changes expected by the basic restructuring plan and the detailed restructuring implementation plan announced by the government. First, it presents several alternative ways to properly divide up the import/wholesales section of Korea Gas Corporation. Second, it examines critical issues such as the method of using gas supply facilities and gas balancing mechanism, and presents adoptable alternatives for each issue. These issues constitute the core of network and market operation rules which need to be in place when adopting an open access system, which in turn is a prerequisite for sales competition. Third, the report examines price systems, including gas commodity pricing and rate-making design for transportation service, by first anticipating the direction of changes in gas rate regulation. Specifically, it presents possible ways to design the service rate for each function of pipeline network and import terminals, and discusses controversial issues in determining total cost-of-service and allocating the cost-of-service to each functional service offered such as distance-related rates, interruptible service rate. Lastly, in relation to the opening of retail

2002-01-30

This paper presented Nova Scotia's policy related to gas distribution. The government of Nova Scotia views natural gas as an economic enabler and is committed to ensuring that natural gas is available and accessible to Nova Scotians where it is economically feasible. Natural gas will give the province an efficient and clean burning energy supply that will make existing businesses more competitive. The province will support and facilitate the construction and operation of a gas distribution system by the private sector and will ensure that there is regulatory oversight by the Nova Scotia Utility and Review Board to protect the public interest. The government will also develop a plan for early conversion of government buildings to natural gas. This paper described the province's policy on gas distribution in relation to: (1) a province-wide franchise, (2) a supplemental franchise, (3) cost of service/performance based rates, (4) postage stamp rates, (5) a Maritimes and Northeast lateral policy, (6) direct access/bypass, (7) existing direct access user, (8) bundling of gas sales and other products and services, (9) licensing of gas marketers, (10) benefits, (11), regulatory efficiency, (12) municipal taxes, and (13) municipal operating agreements.

GRTgaz is a European leader in natural gas transmission, a world expert in gas transmission networks and systems, and an operator firmly committed to the energy transition. It owns and operates the gas transmission network throughout most of France and it manages the transmission network in Germany, thereby helping to ensure correct operation of the French and European gas market. It contributes to the energy security of regional supply systems and performs a public service mission to ensure the continuity of consumer supply. This document presents some key figures about GRTgaz activity in 2015: Gas consumption resumed despite warm conditions in 2015. Gas demand for power generation in gas-fired power plants has strongly increased, due to favourable economic conditions. 2015 was characterised by the lowest LNG imports to France ever, which entailed a still intensive use of the North-South link, despite transits to Spain and Italy back to 5 year average level.

Government policy and access to natural gas service in Canada

International Nuclear Information System (INIS)

Plourde, A.; Ryan, D.L.

1995-01-01

As part of the Canadian energy policy between the mid-1970's to the mid-1980's, consumers were encouraged to use fuels alternative to oil. The first set of policy issues involved measures to provide consumers with incentives to switch to non-oil-burning equipment, whereas the second set of. policy papers emphasized the expansion of the natural gas distribution system. More than $1 billion have been spent on the gas pipeline expansion project. Consequences of program expenditures in each province were examined. With the exception of Manitoba, it was found that annual net pipeline additions were higher during the program period, indicating that the program policies induced these activities to occur sooner than if the policies were not in place. Kilometres of gas pipeline per individual constructed was highest in Quebec, where construction proceeded mainly between the more densely populated centres. In contrast, in Saskatchewan and Alberta, the program encouraged natural gas pipeline construction in rural areas with lower populations. Without the program, these areas may not have had access to natural gas for a very long time. It was concluded that, in this, and some other instances, public investment had the effect of accelerating developments, or encouraging the completion of projects that otherwise would not have been undertaken. It was suggested that in the future decision-makers consider the costs of changes in activity patterns prior to designing such programs. 2 figs., 1 table

Natural gas cost for evaluating energy resource opportunities at Fort Stewart

1993-01-01

Ft. Stewart, a United States Army Forces Command (FORSCOM) installation located near Hinesville, Georgia, is currently undergoing an evaluation of its energy usage, which is being performed by Pacific Northwest Laboratory. In order to examine the energy resource opportunities (EROs) at Ft. Stewart, marginal fuel costs must be calculated. The marginal, or avoided, cost of gas service is used in conjunction with the estimated energy savings of an ERO to calculate the dollar value of those savings. In the case of natural gas, the costing becomes more complicated due to the installation of a propane-air mixing station. The propane-air station is being built under a shared energy savings (SES) contract. The building of a propane-air station allows Ft. Stewart to purchase natural gas from their local utility at an interruptible rate, which is lower than the rate for contracting natural gas on a firm basis. The propane-air station will also provide Ft. Stewart with fuel in the event that the natural gas supply is curtailed. While the propane-air station does not affect the actual cost of natural gas, it does affect the cost of services provided by gas. Because the propane-air station and the SES contract affect the cost of gas service, they must be included in the analysis. Our analysis indicates a marginal cost of gas service of 30.0 cents per therm, assuming a total propane usage by the mixing station of 42,278 gallons (38,600 therms) annually. Because the amount of propane that may be required in the event of a curtailment is small relative to the total service requirement, variations in the actual amount should not significantly affect the cost per therm.

Rising prices squeeze gas marketer

Apollo Gas, a Toronto-based gas marketer, is considering options to enhance unit holder value, including sale of its 21,000 gas supply contracts, just weeks after it was forced out of the Alberta market by rising gas prices. Although the company had reported first quarter revenues of more than $15 million and earnings through that period of about $2.1 million, increases of 33 per cent and 38 per cent respectively over the same period in 1999, the company is resigned to the fact that such performance markers are not likely to be reached again in the foreseeable future, hence the decision to sell. About 95 per cent of Apollo's current transportation service volumes are matched to existing fixed-price supply contract which are due to expire in November 2000. After that, it is about 75 per cent matched for the balance of the term of its customer contracts (mostly five years). This means that the company is exposed to market prices that are likely to continue to increase. If this prediction holds true, Apollo would be forced to purchase the unhedged volumes of gas it needs to service its customers in the spot market at prices higher than prices the company is charging to its customers.

Conceptualizing urban household energy use: Climbing the 'Energy Services Ladder'

International Nuclear Information System (INIS)

Sovacool, Benjamin K.

2011-01-01

This article begins by defining energy services and identifying how they differ according to sector, urban and rural areas, and direct and indirect uses. It then investigates household energy services divided into three classes: lower income, middle income, and upper income. It finds that the primary energy technologies involved with low-income households involve a greater number of fuels and carriers, ranging from dung and fuelwood to liquefied petroleum gas and charcoal, but a fewer number of services. Middle-income households throughout the world tend to rely on electricity and natural gas, followed by coal, liquefied petroleum gas, and kerosene. These homes utilize energy to produce a much broader range services. The upper class or rich have access to the same energy fuels, carriers, and technologies as middle-income homes and families, but consume more energy (and more high luxury items). The study highlights how focusing on energy services reorients the direction of energy policy interventions, that energy services are neither uniform nor innate, and by noting exciting areas of potential research. - Research highlights: → The primary energy technologies involved with low-income households involve a greater number of fuels and carriers, ranging from dung and fuelwood to liquefied petroleum gas and charcoal, but a fewer number of services. → Middle-income households throughout the world tend to rely on electricity and natural gas, followed by coal, liquefied petroleum gas, and kerosene.

By effectively communicating company policies and relevant information concerning the energy situation both to the general public and to employees, public-relations efforts can make a substantial contribution to the success of marketing gas supplies in the future, according to the British Gas Corp. The public's perception of such issues as the availability of gas, assuredness of supply, cost relative to competing sources of energy, environmental impact of gas-industry operations, security of the consumer's investment in major appliances, fairness of pricing policies, quality of the gas product, and efficiency of service will significantly influence the industry's ability to retain a rasonable share of the energy market. To maintain credibility with the public, gas-industry public-relations personnel will have to explain the dimensions and complexity of industry operations while meeting the consumer's expectations for increasing levels of service.

Developing consumption-based greenhouse gas accounts : the carbon footprint of local public service provision in Norway

Energy Technology Data Exchange (ETDEWEB)

Larsen, Hogne Nersund

2011-07-01

This thesis describes the development and application of a tool to assess and document the life cycle greenhouse gas emissions of municipalities and other public-service providers. The model is linked to the financial accounting system of municipalities and counties to calculate the Carbon Footprint (CF) of all purchases/activities made. In particular indirect emissions (Scope 3 according to the greenhouse gas (GHG) protocol) will effectively be accounted for with this system. One of the main findings of the thesis is indeed the importance of Scope 3 emissions to the total CF of the cases investigated. Within the local climate action framework, this thesis focuses on the CF resulting from the activities of the municipal/county administration. This will largely be the provision of services. Insights in the structure of the CF of services will therefore be provided in the papers presented in the thesis. Results show that direct GHG emissions from the burning of fossil fuels are not very significant. At the same time, indirect GHG emissions embodied in the purchase of products and services from sub-suppliers are very significant. Furthermore, when time series are investigated, we identify a shift from direct emissions (e.g. the combustion of diesel in municipal vehicles) to indirect Scope 3 emissions (e.g. the purchase of transportation services from a private company). This outsourcing of activities indicates a necessary shift to complete consumption-based inventories that include all direct and indirect GHG emissions in developing comparable indicators of sustainability. The comparability of municipal CFs is the focus of one of the papers in the thesis. In the paper, we investigate how the CF of all Norwegian municipalities compares to a set of key characteristics. The main finding here is that the CF is highly dependent on both municipal wealth and municipal size. Small and wealthy municipalities tend to have a significantly higher CF per capita relating to the

Manocha, J.

1992-01-01

On 26 September, 1991, large volumes of natural gas were observed to be leaking from two water wells in the Town of Jarvis. Gas and water were being ejected from a drilled water well, at which a subsequent gas explosion occurred. Measurements of gas concentrations indicated levels far in excess of the lower flammability limit at several locations. Electrical power and natural gas services were cut off, and residents were evacuated. A state of emergency was declared, and gas was found to be flowing from water wells, around building foundations, and through other fractures in the ground. By 27 September the volumes of gas had reduced substantially, and by 30 September all residents had returned to their homes and the state of emergency was cancelled. The emergency response, possible pathways of natural gas into the aquifer, and public relations are discussed. It is felt that the likelihood of a similar incident occurring in the future is high. 11 figs

Canadian conventional gas at a crossroads : a Ziff Energy white paper

Ziff, P.

2010-01-01

The current low price of natural gas may have a significant and lasting impact on Canada's natural gas industry. This paper discussed the future of Canada's conventional gas industry and presented recommendations for ensuring a competitive and successful industry. Canada's oil and gas producers are increasingly shifting drilling activity towards oil production. The ratio of proven gas reserves to current production is now less than 8 years. As the conventional gas drilling reserve base shrinks, investment levels will also decline. Gas production in the Western Canadian Sedimentary Basin (WCSB) is expected to decline a further 15 per cent by 2020. The strong Canadian dollar has resulted in extensive monetary losses to Canadian gas producers. Service costs to the industry are also high. Recommendations included increased government involvement, new royalty rates, investment in unconventional gas, and regulatory reviews, and low gas production costs. Industry approaches will require involvement from operators, service companies, mid-stream processors, and transporters. 15 figs.

Just one year ago, CERN took delivery of its first bi-fuel vehicles (see article in Bulletin 07-08/2011). Today, the fleet comprises 100 vehicles capable of running with petrol or natural gas. At that time, Véronique Marchal, head of the Site Services section in the GS Department, told us: “We are counting on CERN car users’ environmental awareness to use natural gas fuel whenever possible.” Observations one year later show that... well, let’s say there is still plenty of room for improvement. A new awareness campaign has therefore been launched.   “Running on natural gas reduces carbon dioxide emissions by some 40%,” explains Serge Micallef of the Services Industriels de Genève (SIG), CERN’s partners for this green mobility project. CNG contains 20% biogas, which is carbon-neutral. CNG produces 60 to 95% less pollution overall than ordinary petrol, and it is entirely soot-free. It is true that filli...

A case of industrial safety appraisal for extension of service life of GTK-10-4 gas turbines used at gas transmission stations

It is shown that the extended life and enhanced operational reliability of parts and subassemblies of the most popular GTK-10-4 gas transmission plants are determined by the enhanced efficiency of the control over technical condition and operational safety of turbine plants in conformity with industrial safety requirements imposed on gas pipeline compressor stations. It has been established that the materials of parts and subassemblies of gas turbine plants with different, especially with maximal operating time, shall be exposed to NDT for the purpose of determining the actual mechanical characteristics of these materials with different operating time and calculating residual life. The analysis of damageability and operating conditions has helped to identify parts and subassemblies for repair or replacement with the highest frequency of unacceptable defects. These parts and subassemblies have been shown to include base members of the axial compressor (AC), a turbine housing, an axial compressor rotor, high- and low-pressure turbine (HPT and LPT) discs, a 12-part holder, the housing of the holder of HPT and LPT guiding blades, a sealed baffler, and working and guiding AC, LPT and HPT blades. The most typical operational defects have been enumerated and analyzed. It has been determined that the primary task of the industrial safety appraisal for extending the life of GTK-10-4 with limit-exceeding operating time is to thoroughly examine HPT and LPT discs with more than 130,000 hours of operating time and establish by DT methods characteristics of materials for evaluation, taking account of their degradation, and residual life of critical turbine elements. In addition, it has been shown that the service life of HP turbine discs can be extended by replacing the disc material (EP-428 12% chromium steel) with a material with a higher linear expansion factor that somewhat exceeds the expansion factor of EI-893 nickel alloy used to melt out working blades.

Diversification became a necessity to Piedmont Natural Gas Co. as it increasingly faced curtailments and restrictions on supplies from its single energy source, Transcontinental Gas Pipeline Corp. Passage of the Natural Gas Policy Act of 1978 marked the beginning of a turnaround in Piedmont's sharply curtailed gas supplies, keeping Piedmont totally involved in both conventional marketing and construction and expansion into diversified operations. Its diversifications include (1) a program of energy-saving conservation services, (2) formation of a propane gas division, and (3) distribution of fuel oil, all of which helped Piedmont become a full-service energy-distribution system.

The range of business opportunities currently available for the midstream oil and gas business were discussed with particular focus on storage opportunities. Alberta Energy Co. (AEC) Ltd.'s two midstream business units include AEC Pipelines and Gas Processing, and AEC Storage and Hub Services. These two businesses provide the company with good investment returns, stable cash flow, and some significant strategic synergies with their exploration and production businesses. In 1988, the AECO C Hub in southeastern Alberta was created as an outgrowth of AEC's gas production operations on the Suffield block, where they had depleted gas reservoirs with high rock quality suitable for high deliverability storage. With the AECO C Hub, AEC was able to offer firm storage contracts of from 1 to 20 years, and to introduce short term interruptible parking and lending services, title exchange, a spot price index for greater price discovery, and an electronic nomination system. AEC is currently completing construction of their second commercial storage facility, the Wild Goose project, in northern California. D ebottlenecking' the Western Canada supply basin should provide additional opportunities for further expansion not only for AEC but also for other midstream service providers. Opportunities are especially available in the areas of new storage facilities to serve location-specific needs, replacement of declining storage capacity, replacement of retiring facilities, technological optimization of existing facilities, more flexible, higher deliverability facilities and commercial optimization of existing facilities. A map of the hubs and market centres of North America are included. 5 figs

An overview of the Bulgarian natural gas industry is presented. The starting point was the discovery of the indigenous Chiren gas-field in 1967. The first agreement with the ex-USSR for supply of natural gas and construction of main pipelines was signed in 1968. The state gas company BULGARGAZ is responsible for transportation, storage, distribution, processing and marketing of the gas to over 150 industrial companies in the country, as well as for the transportation services to gas importers in neighboring Turkey. The GAZSTROJMONTAZH company accomplish the construction of the local and transit pipelines to Turkey and Greece, as well as of some objects in Iran, Syria, Ukraine and Germany. In the past 20 years, 87890 million m 3 natural gas from Russia are supplied and 846 million m 3 - from domestic sources. The share of natural gas in the overall energy balance is 13.6% for 1992. The restructuring and further development of gas industry require to take into account some factors as: security in supply; investments for technical assurance; pricing policy for natural gas; development of private business.

Science.gov (United States)

Hu, Junzhi; Zhou, Jiyong; Li, Siyuan

2017-06-01

Small-scale air compressor and gas receiver are used as the driving gas of the emergency cut-off system in gas gathering station. Operation of block valve is ensured by starting and stopping compressor automatically. The frequent start-stop of compressor and the pressure fluctuation pose a threat to the service life of gas receiver, and then affect normal operation of the emergency cut-off system and security of gas gathering station. In this paper, the fatigue life of a pressure vessel with axial semi-elliptical surface crack in the inner wall is analyzed under the varying pressure by means of the theory of fracture mechanics. The influences of the amplitude of pressure fluctuation and the initial crack size on the residual life of gas receiver are discussed. It provides a basis for setting the working parameters of gas receiver of emergency cut-off system and determining the maintenance cycle.

Competitive landscape for gas

International Nuclear Information System (INIS)

Newcomb, J.

1990-01-01

During the 1990s, natural gas will be the critical pressure point for energy and environmental developments in North America, according to the author of this paper. The author points to the forces bearing on natural gas, including the need for new power generation capacity, tightening environmental standards, growing concerns about energy security, cyclical factors in U.S. oil and gas exploration, and changes in the oil services industry. This paper discusses how these external factors will shape gas markets in the 1990s. First, it states that gas will gain market share in power generation through greater use of both existing gas-fired facilities and new turbines by electric utilities. Second, it predicts that the cumulative impact of the Clean Air Act and other environmental legislation having significant consequences for the relative roles of coal and natural gas, particularly during the late 1990s. Third, it points to the eventual reawakening of energy security concerns, focusing attention on developing North America's sizeable gas reserves. Finally, it states that while the long-term view of a gas supply crisis without a rebound in drilling activity is accurate, it has been disastrously wrong in the short term. This had led to underestimation of the amount of extra gas that can be provided in the interim from conventional areas at relatively low cost

3D finite element modeling of in-service sleeve repair welding of gas pipelines

International Nuclear Information System (INIS)

Alian, Ahmed R.; Shazly, Mostafa; Megahed, Mohammad M.

2016-01-01

The present work investigates the influence of welding sequence and scheme on residual stresses induced during in-service sleeve repair welding of gas pipelines. For this purpose, a 3D thermo-mechanical FE analysis is conducted on an 8″-Schedule-20, API 5L-X65 steel pipe. Two welding sequences for the sleeve-pipe circumferential fillet welds are compared in the present study: sequential welding in which one side of the sleeve is welded first and then the other side is welded by the same welder, and simultaneous welding in which both sides of the sleeve are welded concurrently by two welders. Within the simultaneous welding sequence, four different welding schemes, designed to investigate the influence of the number of welders and welding directions on residual stresses, are investigated. The results show that the sequential welding sequence induces less residual stresses and distortions. Within the simultaneous welding sequence, the back-step welding scheme is found to induce the least average residual stresses as compared to other welding schemes. - Highlights: • We model in-service sleeve repair welding using 3D FE. • Model was validated through comparison with existing experimental results. • The study presents results on the effect of both welding sequence and welding scheme on the resulting residual stresses. • Sequential welding sequence generates lower residual stresses than simultaneous welding sequence. • Back-step welding scheme generates the lowest average residual stresses along the pipe circumference.

Operation and management of aging gas distribution systems

Energy Technology Data Exchange (ETDEWEB)

McNorgan, J.D. (Southern California Gas Co., Los Angeles, CA (United States))

1993-05-01

Southern California Gas Company, transports billions of cubic feet of natural gas through large-diameter, high-pressure transmission lines, across hundreds of miles of varying terrain, to satisfy the needs of over four and a half million customers. Operating an aging gas system can be truly expensive. Repair costs are very high. Recent figures experienced by our company show that it cost over $800 to repair a main leak, $400 to replace a service, and over $40 a foot to replace even small sized mains. A hidden cost is the effect of the physical limitations imposed by an aging system. It could be under-sized, or limited to a low pressure, thus restricting the volume of gas that can be delivered. Additionally there is the potential loss of valuable gas through leaks or blow downs when making repairs or replacements, and the damage it could do to the environment. For some years Southern California Gas Company has had on-going special and routine pipe replacement programs. The special pipe replacement program is driven primarily to increase the safety of the system, while at the same time improving reliability of service to the customers and reducing their total costs.

Santo, Y [Osaka Gas Co. Ltd., Osaka (Japan)

1994-12-01

This paper describes an outline of natural gas industries in Europe and America, introduction of competition to gas industry in the USA, introduction of competition to gas industry in the UK, and gas industries in the continental Europe. For the new gas distribution system in the USA, pipeline enterprises are permitted to do only transportation services. Sale of gas is based on the direct contract between producers and distributors. In the UK, the British Gas Corporation (BGC) was converted into the private British Gas plc (BG) in 1986. With introducing the competition conditions, the BG has drastically modified its organization, to divide it into the domestic gas division, overseas gas division and the division of development and production of gas. As a consequence of the introduction of competition conditions, the market share of BG has drastically decreased. Moreover, gas industries in Germany, France, Italy, Spain, Belgium, Austria and the Netherlands are briefly described. 4 figs.

Natural gas market assessment: Long-term Canadian natural gas contracts

International Nuclear Information System (INIS)

1992-08-01

A descriptive analysis is presented of the changes which have occurred and the developing trends in the long-term Canadian contracts governing the sale of western Canadian gas into the domestic and export markets from 1985 to 1991. The report is limited to domestic and export contracts for Canadian gas and does not include imported gas under contract. Contract structures prior to deregulation, the changing role of long-term contracts, size and duration of long-term contracts, and terms and conditions of long-term contracts are discussed. Important changes since the mid-1980s include: increased flexibility in long-term contracts enabling the parties to respond more readily to changing supply and demand conditions; greater balance between the buyer's obligation to purchase and the seller's obligation to deliver; flexible and increasingly simple pricing terms that track competitive market conditions; shorter contract terms; reduced contract volumes as smaller end-users and producer/marketers enter the market; and unbundling of gas sales and transportation service providing a wider range of contracting choices and options. 36 figs., 2 tabs

Conceptualizing urban household energy use: Climbing the 'Energy Services Ladder'

2011-03-15

This article begins by defining energy services and identifying how they differ according to sector, urban and rural areas, and direct and indirect uses. It then investigates household energy services divided into three classes: lower income, middle income, and upper income. It finds that the primary energy technologies involved with low-income households involve a greater number of fuels and carriers, ranging from dung and fuelwood to liquefied petroleum gas and charcoal, but a fewer number of services. Middle-income households throughout the world tend to rely on electricity and natural gas, followed by coal, liquefied petroleum gas, and kerosene. These homes utilize energy to produce a much broader range services. The upper class or rich have access to the same energy fuels, carriers, and technologies as middle-income homes and families, but consume more energy (and more high luxury items). The study highlights how focusing on energy services reorients the direction of energy policy interventions, that energy services are neither uniform nor innate, and by noting exciting areas of potential research. - Research highlights: {yields} The primary energy technologies involved with low-income households involve a greater number of fuels and carriers, ranging from dung and fuelwood to liquefied petroleum gas and charcoal, but a fewer number of services. {yields} Middle-income households throughout the world tend to rely on electricity and natural gas, followed by coal, liquefied petroleum gas, and kerosene.

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

International Nuclear Information System (INIS)

1994-12-01

This study evaluates the performance of Australian's natural gas utilities against world best practice. In particular, it examines whether Australia's traded goods sector is disadvantaged by the performance of domestic infrastructure service industries. It reports on the operating efficiency of the natural gas industry using Data Envelopment Analysis. It concludes that the Australian gas industry as a whole is performing relatively well in term of operating efficiency and that its prices are comparable with prices in North America, once differences in consumption per customer are taken into consideration. Appendixes 1 and 2 provide a summary of the structure and regulation of the gas supply industry in Australia and selected overseas countries, while the Appendix 3 gives an econometric analysis of the relationships between consumption per customer and residential price-cost margins. refs., tabs., figs

Beyond the gas bubble

International Nuclear Information System (INIS)

Hilt, R.H.

1990-01-01

The deliverability issue currently being discussed within the natural gas industry involves both near-term and long-term questions. In the near-term, over the next two or three years, it is probable that the natural gas industry will need to mobilize for much greater levels of investment than have been the experience over the past few years. In the longer-term, it is expected that new opportunities for gas will arise as the nation seeks to meet increasing energy requirements within new environmental constraints. Methane for emissions control, CNG vehicles, expanded gas-fired electricity generation, and increased efficiency of traditional energy services are just a few examples. The issues in the longer-term center on the ability of the gas industry to meet increasing supply requirements reliably and at cost-competitive prices for these markets. This paper begins by reviewing the historical situation of gas deliverability that is the capability of the gas producing and transportation portions of the industry. The delivery system's ability to handle shifts in the centers of consumption and production is discussed, with an emphasis on regional problems of gas deliverability and potential bottlenecks. On the production side, the paper reviews the capability and the required investment necessary to handle an orderly transition to a stable supply and demand balance once the elusive bubble had finally disappeared

Need and design of short-term auctions in the EU gas markets

International Nuclear Information System (INIS)

Vazquez, Miguel; Hallack, Michelle

2013-01-01

In the EU, gas markets are based on socializing network flexibility services. However, shippers have different preferences on network flexibility, which are not reflected in current allocation models. We propose the introduction of auction mechanisms to allocate network services in the short run. The auction aims to represent simultaneously the diversity of players′ preferences and the trade-offs implied by network constraints. Two sealed-bid auctions are proposed: (a) an auction based on bids for gas, which allocates network services through the minimization of gas price differences; (b) an auction with explicit bids for line-pack, which allows shippers′ valuation of line-pack storage. - Highlights: • EU gas regulation faces serious difficulties in network resource allocation. • We propose two short-term auctions with implicit network allocation. • The difference between the two is the implicit or explicit allocation of line-pack. • The first auction considers line-pack as an instrument to arbitrage gas prices. • The second auction design considers line-pack as a tool to hedge volatility

Papers of the Canadian Institute's forum on natural gas purchasing strategies : critical information for natural gas consumers in a time of diminishing natural gas supplies and higher prices

International Nuclear Information System (INIS)

2003-01-01

This conference provided insight into how to prosper in an increasingly complex natural gas marketplace. The presentations from key industry players offered valuable information on natural gas purchasing strategies that are working in the current volatile price environment. Diminishing natural gas supplies in North America mean that higher prices and volatility will continue. Other market challenges stem from potential cost increases in gas transportation, unbundling of natural gas services, and the changing energy marketing environment. The main factors that will affect prices for the winter of 2004 were outlined along with risk management and the best pricing strategies for businesses. The key strategies for managing the risks associated with natural gas purchase contracts were also reviewed, along with the issue of converging natural gas and electricity markets and the impact on energy consumers. The conference featured 15 presentations, of which 4 have been indexed separately for inclusion in this database. refs., tabs., figs

Energy market liberalization is a world trend that has prompted the deregulation of natural gas and electricity over the past twenty years in North America. The Ontario Energy Board and the National Energy Board are conducting public hearings on natural gas regulation in response to the request by Canadian energy industries for better regulatory streamlining. The following 5 issues regarding natural gas regulation in Canada have been examined: (1) system gas in a regulated market, (2) natural gas infrastructure investments and capital renewal, (3) improving efficiency in gas regulation, (4) expectations of performance-based regulation (PBR) in the natural gas industry, and (5) the debate whether further deregulation of the natural gas industry is beneficial. This paper examines if a competitive market exists in natural gas distribution and discusses the opportunities for further deregulation of the distribution and storage aspects of the industry. It was noted that the regulatory regime in Ontario will depend on how the Ontario Energy Board deals with issues regarding natural gas storage services. This paper also examines if new storage facilities can charge cost-based or market-based prices as well as the appropriate rate of return on capital to be used to determine those rates. It also examines what the requirement for non-discriminatory access to and from new storage facilities to the Dawn Hub and access to transmission capacity on Union Gas's Dawn to Trafalger pipeline system. Alternative fuels, franchises, bypasses, gated communities, distributed generation, market power and policy issues are the main factors that are considered in assessing the competition in natural gas distribution. It was concluded that further deregulation of the natural gas distribution system in Ontario is not warranted since there is not much possibility in developing a competitive market for distribution services in the short-term.

1997-01-01

The Russian Federation holds the world's largest proven natural gas reserves, and produces more natural gas than any other nation. Russian exports of gas to Europe and the other nations of the Commonwealth of Independent States (CIS) have a significant impact on natural gas markets throughout Europe and Asia. The aim of this three part study is to inform the international energy and investment community about the current status of the Russian gas industry and the prospects for its future development through 2010. It is also intended to provide an opportunity for the appropriate authorities in the Russian Federation to assess the needs of the industry and to consider areas for possible collaboration with the international investment community and international organizations in a rapidly changing economic and business environment. The study was prepared by the Energy Branch of the United Nations Department for Development Support and Management Services (UN/DDSMS). It was financed by the United Nations Development Programme (UNDP). Part I describes Russian gas reserves and potential resources, and overviews the country's gas producing, pipeline and distribution industries. Additionally, it summarizes the markets for Russian natural gas including domestic and external markets. It discusses the primary economics and potential factors that currently impact the Russian gas industry during the Federation's transition toward a market economy. Part II highlights possible directions for the development of the Russian gas resource base, including upstream gas production and downstream marketing in five-, ten- and fifteen-year time frames. It projects export opportunities for Russian Federation gas and evaluates the options for shaping regional and international markets. Part III addresses the legal and regulatory framework and fiscal regime of the Russian gas industry. It also reviews the major investment requirements and the equipment and training needs of the Russian gas

Maritimes natural gas market : an overview and assessment

International Nuclear Information System (INIS)

Booth, G.

2003-01-01

In 1987, Canada's National Energy Board (NEB) adopted a market-based procedure (MBP) to assess long-term gas exports. The MPB included monitoring and assessment of Maritimes natural gas markets. The NEB is responsible for interprovincial and international oil and gas pipelines as well as tolls and tariffs on NEB-regulated pipelines. The NEB is also responsible for electricity and natural gas exports and exploration programs on federally regulated lands not covered by an Accord agreement. The province of New Brunswick requested a new set of rules for the export of natural gas from the Maritimes to ensure competitiveness with other jurisdictions. The NEB decided that the public interest is best served by allowing the market to work. It also decided that the developing Maritimes market faces several challenges not faced by buyers in the export market. It was concluded that the market is working reasonably well to meet the needs of domestic consumers. 20 per cent of Scotian gas is being used in the Maritimes and many laterals have been constructed to extend service. Most major population centres have natural gas. However, there is no residential or commercial natural gas service in Nova Scotia, and only limited penetration of natural gas in residential and commercial markets in New Brunswick. Maritimers have a long history of using other fuel options and must make capital investment to switch to natural gas. They must, therefore, be convinced that investment will pay off in fuel savings and other benefits. The NEB will have to improve price transparency and strive for regulatory efficiency and cooperation with other jurisdictions. 2 figs

This article reports on a postgraduate study at the Swiss Institute of Technology (EPFL) in Lausanne, Switzerland, addressing the prospects for new energy technologies and their development, according to bankers, industry managers and international organisations. The study merges macro-economic, financial and technological views and focusses especially on electricity and natural gas including cogeneration and decentralised, small and middle-size energy production units. The world energy market is changing pace, moving from various monopolies to a dynamic system, with growing decentralisation and networking. The study reveals that constraints are changing due to the economy globalization as well as to the growing internet-based economy, and that new prospects for the development of promising energy technologies are emerging. The demand for more specific energy products like for example uninterruptible power supplies will stimulate new sectors in the energy economy. Growing environmental concern will also be an important factor for the energy market remodelling. For the gas and electricity markets, a considerable rise in sales is expected

Information Erdgas (InfE) in Essen was founded 25 years ago. This was at a time when some initiative was needed to firmly establish the still rather young energy source of natural gas in the German thermal energy market. As a supraregional marketing institution, InfE had a twofold task: Firstly, to start a variety of advertising and information activities to arouse a general interest in natural gas among various consumer groups and create an attractive product image; and secondly, to promote marketing activities locally and support regional and local gas supply companies with a wide range of services. This dual task of InfE, subsidiary to Ruhrgas AG, Germany's largest long-distance gas supply company, has remained the same until today. Of course its spectrum of activities has been rearranged from time to time and adapted to the changed environment. In 1993, VNG in Leipzig was set up as a partner of InfE, offering the same range of services. (orig.) [de

Unbundling the retail gas market: Current activities and guidance for serving residential and small customers

International Nuclear Information System (INIS)

Costello, K.W.; Lemon, J.R.

1996-05-01

The restructuring of retail gas services has followed a typical pattern for previously heavily regulated industries: large customers are initially given rights to purchase unbundled services from different entities, with the same rights dispersed over time to smaller customers. For about ten years now industrial customers in most states have been able to open-quotes play the marketclose quotes. Since the passage of the Federal Energy Regulatory Commission (FERC) Order 636 in 1992, interest has centered on expanding service unbundling to small retail customers, including residential customers. Importantly, the Order prohibited pipelines from providing bundled sales service. This is not surprising - in the telecommunications industry, for example, the unbundling of wholesale services was a strong stimulant for developing competition in the local exchange market. The push for small-customer service unbundling has derived from the basic but politically attractive idea that all retail customers should directly benefit from competitive forces in the natural gas industry. When one looks at the movement of prices since 1985, it is easy to see that large retail customers have enjoyed more favorable prices than other retail customers. For example, over the period 1985 to 1994 gas prices to industrial customers and electric utilities fell around 23 percent and 36 percent, respectively. In comparison, gas prices to residential customers increased by around 5 percent while gas prices to commercial customers decreased slightly by about 1 percent. This report examines various aspects of unbundling to small retail gas customers, with special emphasis on residential customers

Developing an equitable fee structure for gas processing services: JP-90 and beyond

International Nuclear Information System (INIS)

Kingsbury, J.D.; Moller, I.

1996-01-01

The Joint Industry Gas Processing Fee Task Force Report, JP-90, was designed to promote negotiation of gas processing fees that are based on principles of equity and fairness for both natural gas producers and processors. Another purpose of the JP-90 was to develop an effective dispute resolution process for use in those cases where negotiations have failed. At its inception, JP-90 was the only guideline for unregulated fee practices in the oil and gas sector in North America. Today PJVA-95, the revised version of JP-90, is in its final draft. It addresses the changing focus of the gas processing business, and changing regulatory roles in Alberta and British Columbia. A number of other fee mechanisms also have been described, such as the jumping pound formula, fixed fees, fees based on price, wellhead purchases, and others. These mechanisms developed over time to allow the processor and the producer to share the price risk. The changing role of regulatory agencies in fee dispute resolution was also discussed briefly

Status, remaining service-life and quality assurance of PP-materials in flue-gas applications; Status, kvarvarande livslaengd och kvalitetssaekring av PP-material i anlaeggningar foer rening och kondensering av roekgaser

Background: The project is intended to provide a better understanding of how the service life of PP-materials is affected when used in flue-gas applications. It intends to form a basis for the development of relevant techniques and a methodology from which it is possible to give advice and guidance so that the quality of PP-materials can be ensured for a given desired service life. In addition it aims as being able to assess the status and remaining life of PP-materials in current components. Project outline - An inventory, contact and choice of facilities for closer cooperation. Plants with high proportions of PP in the equipment have been prioritised. - Visits to the chosen sites during shut-down periods for inspection and collection of samples from different PP details for further analysis in the laboratory. Collection of operating data and experiences of the use of PP (operating time/exposure conditions in different parts, component substitutions that have been made, etc.). - Systematic studies of the processes and mechanisms for stabiliser consumption over time. - Developing methods and methodology on which advice and guidance can be based so that the quality of PP-materials can be ensured for a given desired service life. The goal is to be able to assess the status and remaining service-life of the PP-materials in flue-gas applications. Results and Conclusions: It has been found that corrosion is relatively rare and that the main factors limiting the use and longevity of polypropylene are the thermal properties (thermal expansion and heat distortion). Leaching of stabilisers from the material is also commonly found but only a few cases of oxidative degradation, as a result of this, have been observed. An important part of the project has been to develop techniques and methodologies to assure the quality PP-material for a desired service life, and to assess the status and remaining life of the PP- materials in flue-gas applications. To do this, samples that

Pressure in the natural gas pipe. Coherence between tariffs for natural gas transport, and congestion in the Netherlands

Boots, M.G.; De Joode, J.; Lise, W.

2005-11-01

Using GASTALE (Gas mArket System for Trade Analysis in a Liberalizing Europe), a comprehensive computational game theoretic model of the European gas market, the Energy research Centre of the Netherlands (ECN) conducted at the request of Gas Transportation Services (GTS) a study on the relationship between gas transport tariffs, the demand for gas transport and possible re-routing of gas flows in Northwestern Europe. We find that lowering the average Dutch transport tariff compared to the average German transport tariff induces a re-routing of gas flows from the German network to the Dutch network. In periods of high gas demand, such as the peak winter season, the lower transport tariffs lead to a high potential demand for gas transport which cannot be fulfilled by the limited capacity of the Dutch gas transport network. This will probably even lead to congestion in the Dutch network as a 'first-come first-served' regime is currently applied in the Netherlands. So Dutch gas transport tariffs being out of line with the gas transport tariffs neighbouring countries, implies that there is a real chance that transit flows are crowding-out gas flows destined for Dutch final consumers of gas. Hence, the security of gas supply for the Netherlands is seriously threatened. These findings are robust for variations in the model assumptions as shown by a number of sensitivity analyses [nl

A study on the development of repair procedure for gas pipelines

1999-06-01

In the buried natural gas pipelines, many defects may occur by construction faults, corrosion, third-party interference and ground movement. When a segment of a pipeline is found to be defective, one of the repair methods is to remove its contents and cut out the defective segment after shutting down the pipeline. However, the cost is extremely high in terms of venting and disrupting the gas supply. Therefore, most pipeline companies have developed in-service repair methods without removing the line from service. In general, in order to avoid removing the line from service, direct deposition of weld metal, full-encirclement sleeve, patches, stopple fittings, half-sole and branch connections are required. There are three important concerns in the sleeve-repair welding like other methods of in-service repair-welding. The first concern is the possibility of burn-through which is due to the localized heating and loss of meterial strength on the inner surface of pipe during the welding process. The pipe wall may burst under internal pressure if the loss in strength is too great. The second concern is the high cooling rates by the flowing gas which quickly removes heat from the pipe wall, resulting in accelerated cooling of the weld. Such rapid cooling rates promote the formation of hard heat affected zone microstructure making these welds susceptible to hydrogen cracking. The third concern is for the load carrying ability, such as tensile strength, fracture toughness and fatigue strength. This study was taken to investigate the effect of in-service welding conditions and assess the mechanical properties for the direct deposition welding and sleeve-repair welding of in-service gas pipelines and develope the welding procedure specification for in-service pipeline repair. 81 figs., 40 tabs.

The involvement of the Calgary-based company NOVA Gas International (NGI) in Malaysia`s peninsular gas utilization (PGU) project, was described. Phase I and II of the project involved linking onshore gas processing plants with a natural gas transmission system. Phase III of the PGU project was a gas transmission pipeline that began midway up the west coast of peninsular Malaysia to the Malaysia-Thailand border. The complex 549 km pipeline included route selection, survey and soil investigation, archaeological study, environmental impact assessment, land acquisition, meter-station construction, telecommunication systems and office buildings. NGI was the prime contractor on the project through a joint venture with OGP Technical Services, jointly owned by NGI and Petronas, the Thai state oil company. Much of NGI`s success was attributed to excellent interpersonal skills, particularly NGI`s ability to build confidence and credibility with its Thai partners.

Trans Ocean Gas CNG transportation development plan

Liquefied natural gas (LNG) transportation is on the rise due to increased global demand for natural gas. However, the challenge of transporting LNG lies in finding suitable locations for import terminals. Compressed natural gas (CNG) transportation offers an alternative method for transporting stranded natural gas to existing markets and for creating new natural gas markets not practical for LNG or pipelines. The founder of Trans Ocean Gas Inc. (TOG) modified an existing fibre reinforced plastic (FRP) pressure vessel technology to safely store CNG on a ship. The newly developed containment system has proven to overcome all the deficiencies of steel-based systems. TOG patented the containment system and will license its use to owners of stranded gas and shipping service providers around the world. Financial support is needed to perform verification testing and for regulatory approval. The CNG systems will be built and assembled throughout facilities in Atlantic Canada. 2 tabs., 3 figs.

Moving Canadian gas - options or confusion?

The question of whether and how much gas carrying capacity is required beyond Chicago was examined. Assuming that the answer is 'yes', how much of the gas should be moved beyond Chicago, and which of the many pipeline options currently available should be chosen, was discussed. PanEnergy, one of the United States' five-largest transporters of natural gas and producers of natural gas liquids, with a base of 37,000 miles of natural gas pipelines, decided to get involved with Spectrum which takes gas away from Chicago, and Excelsior which gets gas into New York City. The Spectrum pipeline is designed to phase-in transport of up to 500,000 Dth/d from the Chicago area to the east coast and other markets served by the PanEnergy pipelines, such as southern Ontario, Kansas City and Memphis. The Excelsior pipeline project has been proposed to get gas into New York City. It is a long term solution designed to meet several years of strong historical and forecasted market growth. At the same time, it is not a new pipeline; it is backed by existing assets and will provide service as early as 1998. 15 figs

Since third party can access to pipelines, those who wish to ship gas between two locations of a gas network have to arrange transportation services. Natural gas transportation is a set of contractual arrangements and has become a complex contracting process. This paper aims at analyzing the typical economic functions of shippers in third-party access regimes in the natural gas industry in a transaction costs approach. Shippers provide and combine intermediation functions in transportation services markets: information management, matching, bundling and transactions guarantees. In this context, the shipper has appeared as a particular market intermediary specialized in transportation arrangements in the new regime of third party access in the natural gas industry. (Author)

Multiple cracking was observed in disc springs made from an austenitic stainless steel and used in large stationary gas turbine engines. It was determined that they failed in service by bending overload. The metallurgical cause of the cracking was found to be grain boundary embrittlement by secondary chromium carbide precipitates. They formed upon heat treatment during manufacture of the components. It was recommended to either alter heat treatment parameters to avoid embrittlement, or to select a different spring steel that does not require heat treatment. (orig.)

The role of marketing advisors in the new deregulated natural gas industry was discussed. These producer-oriented marketing consultants are specialists in providing affordable marketing services to junior gas producers on an `as-needed` basis. The most important service provided by marketing advisors is helping the client identify management problems, analyze such problems and recommend solutions. Accordingly, the marketing advisor should be independent and objective, with no conflict of interests. He/she should be prepared to invest a lot of time and effort in providing the junior producer with a customized diagnosis of its marketing problems. 5 refs., 3 figs.

It is more than thirty years since gas infrared heating for points was introduced on the railway network of what is now Deutsche Bahn. These installations have remained in service right through to the present, with virtually no modifications. More stringent requirements as regards availability, maintainability and remote monitoring have, however, led to the development of a new system of gas infrared heating for points - truly a new generation.

This power point presentation addressed the following topics regarding development of natural gas in eastern Canada: (1) the 18 Tcf of proven natural gas reserves at Sable Island, (2) Canadian markets benefiting from the Maritimes and Northeast Pipeline (M and NP), (3) a 20 year franchise agreement between Enbridge Gas and the government of New Brunswick, (4) the 25 year provincial franchise agreement by Sempra Atlantic Gas, and (5) Sable Island's influence on central Canada. The Sable Offshore Energy Project (SOEP) is now producing about 540,000 MMBtu/day from 6 fields. Plans for Tier 2 expansion are underway. Firm contracts for the M and NP are scheduled to transport gas from the SOEP to markets in Nova Scotia, New Brunswick, Maine and New Hampshire. Sable gas is also a potential supply for the Quebec market. Gaz Metropolitain and Enbridge have proposed to build the Cartier Pipeline from the Quebec/New Brunswick border to Quebec City. It is unlikely that Sable Island supply will directly serve the Ontario market. Canadian customers for Sable gas and M and NP service include pulp and paper companies, oil refineries, power generators and local distribution companies (LDC), with the majority of demand coming form the electric power industry. tabs., figs

The logic of natural gas penetration in Europe

This paper is trying first to bring out some characteristic lines from the thirty years period of natural gas market growth in Europe: triggering role of domestic gas resources, relay by imports, background from an existing manufactured gas industry. The different roles of bulk usages and scattered ones are underlined. Through an example it is showed that market conditions are relying on a rapid shift of the gas prices competitiveness and on the historical opportunity of space heating growth. In a second part, this paper analyses in each great sector of consumption that could sustain the growth to come of natural gas in Europe. This development relies on marketing forces and on the disposal of new usages for gas and new services for customers, with the benefit from technological headway. 8 figs

Distribution of natural gas: introduction of the interruptible segment in Sao Paulo, Brazil; Distribuicao de gas natural canalizado: introducao do segmento interruptivel em Sao Paulo

The principal objective of this paper is the better knowledge and evaluation of the natural gas distribution network interruptible branch. This new service can be appropriate for thermal power generation on flexible dispatch mode, as 'take or pay' contracts surplus jobs. The paper indicates no regulatory restraints in an interruptible network implantation and one can guess that the inexistence of contracts for this service resembles only lack of conjunctural opportunities for this job applications. These difficulties appear both in the supply and distribution branches of the gas business, which prefer flat contracts. The final conclusion is interruptible contracts can be an improvement on the distribution business and certainly can accommodate a suitable demand and supply volumes in the long-term gas market balance.

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.

This preliminary report analyses the desirable evolutions of gas transport tariffing and examines some questions relative to the opening of competition on the French gas market. The report is made of two documents: a synthesis of the previous report with some recommendations about the tariffing of gas transport, about the modalities of network access to third parties, and about the dissociation between transport and trade book-keeping activities. The second document is the progress report about the opening of the French gas market. The first part presents the European problem of competition in the gas supply and its consequences on the opening and operation of the French gas market. The second part presents some partial syntheses about each topic of the mission letter of the Ministry of Economics, Finances and Industry: future evolution of network access tariffs, critical analysis of contractual documents for gas transport and delivery, examination of auxiliary services linked with the access to the network (modulation, balancing, conversion), consideration about the processing of network congestions and denied accesses, analysis of the metering dissociation between the integrated activities of gas operators. Some documents are attached in appendixes: the mission letter from July 9, 2001, the detailed analysis of the new temporary tariffs of GdF and CFM, the offer of methane terminals access to third parties, the compatibility of a nodal tariffing with the presence of three transport operators (GdF, CFM and GSO), the contract-type for GdF supply, and the contract-type for GdF connection.

After 18 months of intense negotiations, the European Energy Council came on December 8, 1997 to an agreement about the internal gas market. The essential point of this guideline is the possibility for some customers to deal with the supplier of their choice. This opening of national gas markets will lead to the disappearance of gas importation monopolies. This paper summarizes the final option retained for the opening of the European gas market, its schedule, the protection of take or pay contracts, and the future perspectives for industrialists (new operators for the storage, transport, terminals management, distribution and trade, diversification of services, competition..).

Share, J.

1997-01-01

In a just-released study, RKS Research and Consulting reported that while power and gas marketing firms may become key players in the deregulated energy business, few of their customers and seeing a national leader emerge. The report said while 75% of large customers interviewed already use energy marketers, only 25% evidence a clear understanding of these firms' skills and product /offerings. The study found that the energy users considered reliable energy supply, service dependability and quality/reliability of fuel sources their top three criteria and apply that to utilities and energy marketing firms. The marketers may offer some unique services, such as a commanding market presence, fuel diversity, skill in using financial derivatives and record of successful risk management, but those offerings are generally at the bottom of the list that energy users use when considering power and gas marketers, the study said. What does this all mean to the gas utilities, both in terms of buying supplies as well as providing gas against their newly emerging competitors? The author asked gas buyers from five LDCs to discuss the challenges they face in doing their jobs today. Their comments are relevant because it is not only an example of a new way of doing business, but is also indicative of the choices and problems one will endure in buying energy in an increasingly deregulated environment. And remember this: the utilities are still the predominant buyers of gas

Tractebel Engineering is undertaking for the Lebanese Ministry of Energy and Water (MEW) advisory services for the launching and for the awarding of a DBOT (Design, Build, Operate and Transfer) contract for the development of a gas transmission system through Lebanon. The service embraces a global approach, integrating legal, market, technical and financial matters, to provide MEW with a clear strategy to its gas development program, aimed at attracting private investors willing to tender on this DBOT project.The Legal Framework Report examines the existing Lebanese legal system and analyzes its suitability to the regulatory framework required to operate gas networks; it also provides recommendations aimed at attracting potential DBOT developers, by facilitating bureaucratic procedures with possible enactment of new laws. The Gas Demand Due Diligence Report provides the market study for present and future demand of gas in Lebanon in the next 25 years (duration of the DBOT contract), with anticipated needs resulting from power generation, industrial sector, commercial and residential sectors. The Pipeline Alternative Solutions Report provides several alternative routing and configurations for the gas transmission pipeline, including surveys, in-land routing (through rough mountain and heavily populated areas), or off-shore routing (through rough marine canyons and sea water depth in excess of 1,500 meters). Basic technical economical study is elaborated for more than 30 options.The Pipeline Financial Optimization Report compares the economics and provides for each solution the expected postal tariff (the compensation that MEW would need to pay to the developer for the execution of the 25 year DBOT contract). The advisory services are completed with preparation of the Pre-Qualification Notice (aimed at selecting a short list of qualified Bidders), preparation of the Request For Proposal (bidding on the selected pipeline option), evaluation of proposal, selection of

Case study of a gas plant alliance at Zama Lake

International Nuclear Information System (INIS)

Clark, S.

1998-01-01

The definition of gas processing effectiveness varies according to whether a producer emphasizes maximized production, or the greatest wellhead netback, or the greatest return on investment. The producer's vision and objectives can change over time, depending on his financial needs, changes in the investment market, shareholder perceptions, or management motivation. This article describes how a third party processor like Novagas Canada Limited (NCL) can help a producer achieve his objectives. The case of NCL's Zama Lake investment and alliance with Phillips Petroleum is used to illustrate the process. Based on this example, a third party processor can provide important midstream services such as raw gas gathering, field compression, gas processing, sales gas transmission, natural gas liquids recovery, transportation and fractionation. In addition, they can provide access to associated energy industries such as oil and electricity, or any combination of the above, by structuring their services to suit the individual needs of each producer. A third party producer can also reduce risk and cost, provide increased reliability, add new processing capacity, and increased netback. Details of how the alliance between NCL and Phillips Petroleum came about and the advantages that each partner derived from the partnership are described. By entering into an alliance with NCL, Phillips Petroleum gained value by divesting risk and acquiring low cost midstream services, while NCL gained by increasing its presence and by adding economies of scale and greater flexibility in its investment decisions

1995-08-01

A new biological flue gas desulfurization process (BIO-FGD) producing sulphur as a by-product was invented by Paques BV and Hoogens Technical Services in 1993. Sulphur dioxide is absorbed from flue gas using a combination of a sodium based scrubber and two biological reactors, an anaerobic and an aerobic biological reactor. The article describes the process and its evaluation in a pilot plant at 2 MW scale, designed to remove 6 kg/hr SO{sub 2} of the 2 million m{sup 3}/hr of flue gas produced at the 600 MW coal fired power station Amer-8 situated in Geertruidenberg in the south of the Netherlands. Research so far has proved the process works successfully and at low cost. A second pilot plant due to start-up in May 1995 will provide data on scale up and further information on sulphur recovery. 5 refs., 5 figs.

2009-05-01

Based on the satellite remote sensing data acquired in 1975 and 2006, and by using the assessment method of ecosystem service value, the dynamic changes of physical production value, gas regulation value, and water storage value of Ruoergai Plateau wetland ecosystem in 1975-2006 were studied. During study period, the total value of the three services decreased from 19.59 billion RMB Yuan to 12.38 billion Yuan RMB, among which, physical production value increased by 0.302 billion RMB Yuan, while the gas regulation and water storage value decreased by 7.507 billion RMB Yuan. The benefit from the increase of physical production was much less than the loss of ecosystem degradation. Overgrazing induced the biomass reduction and soil deterioration, resulting in the decline of Ruoergai Plateau wetland ecosystem service value and service capacity.

Development of a Comprehensive Energy Service Business Model

Energy Technology Data Exchange (ETDEWEB)

Lee, S.K. [Korea Energy Economics Institute, Euiwang (Korea)

2001-11-01

Traditionally, energy industry has been regarded as supply- oriented and characterized by its vertically integrated structure and monopolized market. In particular, network industries such as electricity, natural gas, and district heating and cooling, because of their large initial capital investments, were inevitably state-owned. As their sizes have ever increased, government-owned corporations are confronted with internal crises such as financial limitations, increasing internal transaction costs, etc. In addition to these internal problems, fundamental changes in the external environment such as advances in communication and modular technologies, globalization, and market liberalization have forced energy industries to undergo a restructuring process. Restructuring in the energy industry is intended to introduce competition in the market by unbundling the energy service into production, transportation, and distribution. The energy service has been vertically as well as horizontally integrated by suppliers. Restructuring, which has been implemented in the United States and the European countries, is now being introduced in Korea. However, energy services have not yet been regulated as a separate industry even in those countries which are well advanced in their restructuring. WTO negotiation is under way to separate the service sector in 'General Agreement on Tariffs and Trade(GATT).' Areas that can be categorized as a service sector are 17 subdivided sub-sectors as dispersed in each sector. Energy service business models expected to be emerged in the restructuring process of energy industry include: transmission/trunk pipeline projects, distribution/local pipeline projects, trading, brokerage, metering service, local distribution of natural gas, to name a few, for electricity and natural gas sectors; rational use of energy such as CES business and ESCOs for district heating and cooling, and energy conservation sector. Rational use of energy, in

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

Natural gas market assessment: Price convergence in North American natural gas markets

International Nuclear Information System (INIS)

1995-12-01

The extent to which Canadian and U.S. natural gas markets have become integrated in the post-deregulation era was assessed. This assessment was accomplished through a statistical analysis of the price movements in Canadian and U.S. gas markets. The analysis pointed to three broad conclusions: (1) on the whole, there has been an increasing degree of integration among North American natural gas markets since price deregulation and the introduction of open access, (2) there is somewhat of a split between eastern and western markets, (3) Alberta's links are stronger with the western U.S. natural gas market than with the market in the eastern U.S. Several factors were cited as contributing to the general increase in market integration, including: (1) increased pipeline capacity and additional pipeline interconnections, coupled with the development of market hubs, (2) improved flexibility of access to pipeline transportation services, (3) improved access to market information and greater trading flexibility which has been facilitated by growing use of electronic bulletin boards and electronic trading systems. The increased market integration was claimed to have benefited both consumers and producers, and to have increased competition in both countries.. 28 refs., 14 figs

An overview of what is in store for gas purchasing in Ontario's new deregulated market was presented. Basically, responsibilities will shift from the utility to market players. The impact of this shift on marketers, on end-users and on the utility were assessed. In the new millennium, Consumers Gas, which is Canada's largest and oldest natural gas distributor, will be operating under a new name, Enbridge. The company will focus on developing marketing programs to position natural gas as the number one fuel choice for residential, commercial, apartments, vehicles, cogeneration and industrial markets. The evolution of the 200 customer market model( i.e. large volume customers, gas marketers, commercial customers and residential customers as a group), what each of these groups want from Enbridge, and what Enbridge can deliver as the wholesale provider of natural gas delivery services rounded out the discussion. figs

Smith, D.J.

1992-01-01

This paper reports that long-term economical and reliable fuel contracts are imperative for increased use of natural gas. Demand for natural gas grew by 3.3% in 1991 to 19.3 trillion cubic feet (tcf) according to the U.S. Department of Energy's Energy Information Administration (EIA). during 1992, EIA expects natural gas demand to grow about 1.8%. However, EIA predicts that natural gas demand will be down slightly in the electric power sector. This is despite the potential for continuing lower gas prices and availability. wellhead prices for natural gas fell by more than 9% in 1991. Although EIA forecasts a decline in natural gas use by electric utilities, a study undertaken by ICF Resources for Enron Power Services, Inc. expects natural gas consumption in the power industry to increase in the 1990s. ICF says that the growth will occur because many new plants will be gas-fired, many existing electric utility power plants designed for oil and/or natural gas operation will use natural gas, and about half of new non-utility power plants will be gas-fired

The opening of the domestic gas market in the UK

1998-01-01

The deregulation of the gas market in the UK raises several difficulties. The door-to-door canvassing which has been used to incite customers to change their suppliers has led sometimes to complaint actions. Thus, price reductions were preferentially attributed to direct-debit customers and not to those that use gas meters with pre-payment tokens. In this context, the commercial reaction of British Gas company has been to propose new services concerning not only natural gas but also electric power and water distribution and sometimes also telephone.

Problems of gas marketing, particularly with respect to Swiss conditions

Energy Technology Data Exchange (ETDEWEB)

Hunzinger, W

1981-07-01

Rising gas prices have required a change in Switzerland's marketing strategy to a greater emphasis on the residential, commercial, and service sectors. A Swiss committee on energy in 1978 reported on three different scenarios for Swiss energy development. Excluding district heating and cogeneration use, natural gas consumption, though modest by world standards, grew 13.3% in 1979 to reach 7848 GWhr, or 4.2% of the total energy consumption. The Swiss gas industry association in 1979 began an information campaign to send out a series of six letters about gas.

Risk analysis for a local gas distribution network

International Nuclear Information System (INIS)

Peters, J.W.

1991-01-01

Cost control and service reliability are popular topics when discussing strategic issues facing local distribution companies (LDCs) in the 1990s. The ability to provide secure and uninterrupted gas service is crucial for growth and company image, both with the public and regulatory agencies. At the same time, the industry is facing unprecedented competition from alternate fuels, and cost control is essential for maintaining a competitive edge in the market. On the surface, it would appear that cost control and service reliability are contradictory terms. Improvement in service reliability should cost something, or does it? Risk analysis can provide the answer from a distribution design perspective. From a gas distribution engineer's perspective, projects such as loops, backfeeds and even valve placement are designed to reduce, minimize and/or eliminate potential customer outages. These projects improve service reliability by acting as backups should a failure occur on a component of the distribution network. These contingency projects are cost-effective but their longterm benefit or true value is under question. Their purpose is to maintain supply to an area in the distribution network in the event of a failure somewhere else. Two phrases, potential customer outages and in the event of failure, identify uncertainty

In this paper it will be discussed how to most effectively give room to competitive forces in natural gas markets, given the traditional merchant pipeline as point of departure. Alternative models of organizing the market will be reviewed: we first consider decreasing barriers to entry and then analyze advantages and drawbacks of a third party access system. In this context different forms of implementing a competitive market for transportation capacity and coordinating it with gas trade are discussed, among them a simultaneous auction of gas and transmission capacity. Finally a hub system of point markets in conjunction with third party access will be suggested to allow for competitive markets for gas and transportation service. 33 refs

An overview of the new TransCanada energy transmission system was given. TransCanada has ownership interests in seven other North American natural gas pipelines and the integration of former NOVA Gas Transmission, TransCanada Energy Transmission and ANG Pipeline organizations into a single organization is nearing completion. Integration efforts have been driven by TransCanada's commitment to provide customers with lower costs and improved service levels. The service enhancements will include one-stop shopping, customer advisory councils, harmonized design criteria, optimized operations/maintenance, and consistent billing processes. The new toll design which will replace the current postage-stamp pricing regime offered by NGTL was also reviewed, emphasizing key features such as pricing, term linked tolls, interruptible/short term tolls, renewal incentive, risk/reward collar, transition period and new services

Three examples of natural gas distribution companies involved in merger activity illustrate how the distribution as well as the transmission side of the industry may be attractive to potential acquiring companies seeking diversification. Although the mergers are a new phenonmenon, the acquiring firms are attracted by the overlapping service areas and the operating efficiency of the regulated distributors. They also see a possible outlet for surplus natural gas. 1 table.

Sweden is - except Iceland, Cyprus and Malta which have no gas at all - the country in Europe where natural gas plays the smallest role. The report raises and answers the question of why Sweden, unlike the rest of Europe, never built an extended natural gas networks. It also addresses the historical and future development of natural gas in Europe. An effective competition stopped the expansion of natural gas in Sweden. The Swedish gas projects offered state aid that was equivalent to the support given the rest of Europe. But competition and price worked better in Sweden than in many parts of Europe in 1960, the 1970s and into 1980s. It made an investment in a natural gas system unprofitable or in at least involving too large a financial risk to attract investors. Low or no profitability is still factors affecting natural gas futures in Sweden. There is also a political resistance. Therefore, there is hardly any reason to believe that major new gas projects would attract either new owners or funding organizations. Based on a commercial basis, only a specific and strongly limited expansion can come about. Over the next few years, the EU will need to sharply increase imports of natural gas just to maintain current consumption. The domestic European gas production is steadily decreasing. This means that new delivery systems, new contracts and new gas fields have come at a rate close to the border of what is technically, economically and politically possible. There is hardly any other option than increasing imports of Russian gas for the foreseeable future. In the long term, in addition to Russia, the OPEC countries will become major gas suppliers to Europe. In a medium term perspective, the question of whether Europe has time to expand its import capacity. It is also uncertain if the exporting countries Russia, Algeria, the former Soviet republics east of the Caspian Sea, Nigeria and Qatar, can or want expand its capacity to export.

an important verification that the plant fulfills the expectations. One important thing, however, is not to accept the test uncertainty as a test tolerance since it will provide the manufacturer overwhelming and unfair odds. Nowadays, it is common to have a maintenance agreement at some level for risk mitigation. There are different levels of contractual services ranging from parts agreement to full coverage 'bumper-to-bumper' LTSA services. One can chose to use either the OEM or another (third party) service provider. In many cases, the financing organs or insurer requires an LTSA (or better) for risk mitigation to level the insurance cost at a reasonable level. There are ways of potentially reducing the maintenance spending and one should always avoid lumped methods with equivalent hours. The word 'lumped' is used in a sense that the two different ageing mechanisms (creep, oxidation, regular wear and tear and stresses related to thermal gradients during start and stop) are evaluated as equivalent time by e.g. assuming that a start consumes time rather being a low cycle. A competent monitoring system can be a good investment - even if only a single failure can be avoided. The total world-wide gas turbine fleet is in the order of 47 000 units and the total value of the gas turbine after market was 2009 13.8 BEuro (13.8x10{sup 9} Euro). The after-market is, indeed, valuable to the manufacturers since all 47 000 units requires maintenance on a regular basis. Certain in-house produced parts may be offered with several hundred percent's margin - in contrast to about ten percent for a complete new turn-key power plant. The reward for the user, by having a LTSA, is discounted parts and prioritized treatment by the supplier. The combined cycle has about half the carbon dioxide emission compared to a coal fired plant. The large difference is driven by the higher efficiency and the higher hydrogen content in natural gas. This in combination with the

Although the gas and electricity markets have their organizational and operational idiosyncrasies, the principles of a competitive market apply to both. The gas industry model of functional and services unbundling, and the elimination of the pipeline merchant function should be emulated. This process of one industry learning from another is inevitable as electricity and natural gas come to be traded in a nearly unified energy market. As their markets merge, two once-distinct industries will be come much more alike, each borrowing the best features of the other and leaving less-desirable features behind. Factors are discussed

Onsite gas storage for industrial customers

International Nuclear Information System (INIS)

Shikari, Y.A.

1990-01-01

The changing pattern of industrial gas marketing in the United States and other countries has placed new pressures on industrial users to assume responsibility for assuring their own supply. Technological changes in manufacturing processes have placed greater emphasis on assuring fuel quality and many processes can no longer tolerate near-substitutes such as distillate fuel oil and LPG. One way to take advantage of lower cost interruptible gas service contracts is to provide stand-by sources of gas onsite which can be used when the primary supply is curtailed. This paper describes the methods which an industrial gas consumer could use to store gas onsite (or close by an industrial factory) and their technical and economic advantages or limitations. The regulatory factors such as environmental and safety issues are reviewed and the advantages and disadvantages of each method are described. The application of emerging technologies such as storing natural gas on adsorbents at low pressure and solid absorption in LPG are reviewed and the research needed to make them acceptable is discussed. The potential applications in the marketplace are also discussed and the economics of onsite storage of natural gas is compared to other alternatives. (author). 11 refs, 5 figs, 1 tab

The energy saving possibilities of CDS (Commodity Services System) for large-scale consumers. Calculating and combining for an ideal mix

International Nuclear Information System (INIS)

1999-01-01

Gasunie's new price scheme, the Commodity Services Sector (CDS), will soon apply to all large-scale consumers. Although the scheme is complicated, it does offer various opportunities to reduce the gas bill. The natural gas price was determined solely by volume, whereas the costs largely depend on the services rendered to the customer such as transmission and capacity. The logical solution is thus to charge the customer separately for the gas and the services. In the future, the gas bill will therefore comprise three elements: commodity (gas), capacity and transmission. As far as capacity is concerned, the user can choose between base capacity, additional capacity, incidental capacity and hourly capacity, depending on the natural gas consumption pattern

The existing interstate pipelines and proposed pipeline projects for the Chicago hub area were illustrated. The presentation explained why energy suppliers in the current competitive market need to balance and manage energy and transportation services for gas-fired power generators in terms of hourly winter and summer peaking services. The new infrastructure of the energy market will include new pipelines, storage and balancing to meet the ever increasing power demand. One of the options to meet power demand is to increase natural gas supply, transportation, storage, and hourly balancing capabilities. Other options are to build nuclear or coal-fired power generating facilities, or to go with renewables such as solar and wind power. Energy conservation and the reduction of natural gas usage per capita is another option to eliminate blackouts. This presentation also addressed the role that local distribution companies (LDC) and unbundling will play in the choice of these options. tabs., figs

Effects of interruptible natural gas service: Winter 1989--1990

International Nuclear Information System (INIS)

1991-07-01

During the extreme winter conditions experienced in December 1989, petroleum products showed dramatic price increases. Supply of certain products such as propane reached critical levels. Numerous factors contributed to the heating fuel situation, including well freeze-ups and refinery problems, as well as difficulties associated with delivery of the product. An area of concern identified in the ensuing debates was the impact of customer requirements for petroleum products resulting from curtailment of natural gas purchases under interruptible contracts. The lower rates associated with interruptible contracts make them an attractive choice for electric utilities. However, they require that the customer be prepared to obtain adequate fuel supplies in the event of curtailments. Electric utilities prepare for these contingencies with stocks of alternative fuels. Particularly in cold climates, interruptible has contracts are part of doing business. The extent and duration of the interruptions faced by customers relate principally to weather factors. Previous EIA studies investigated on a national level the causes of the dramatic price increases seen in petroleum product markets in the 1989--1990 heating season. This study is in response to a request from Senator Timothy Wirth, Chairman, Subcommittee on Energy Regulation and Conservation, to study in detail the impact of interruptible natural gas contracts as one of the factors cited as contributing to the price increases. A copy of the letter requesting the study is contained in Appendix A

The consequences of liberalisation of the gas market. Part 6. Suppliers

International Nuclear Information System (INIS)

Van Gelder, J.W.

1999-01-01

Deregulation in the energy sector has forced companies to scale up. Natural gas suppliers and installers are confronted with more pressure to cut prices and bigger turnover fluctuations. Companies doing business with gas companies try to escape the consequences of deregulation by developing new products and improving their services. In the sixth and last article in the series on the effects of the liberalisation of the Dutch gas market, suppliers express their concern about the changes triggered by the deregulated market. Challenges and opportunities of deregulation are discussed as well. The bigger companies in the installation sector will be looking for opportunities to render energy services independently or in co-operation with (foreign) partners. For smaller installers, however, co-operation seems to be an interesting option, either with other installers or with energy companies

The deregulation of electricity and gas markets. The great economic challenges

Mirabel, Francois; Guerassimoff, Gilles

2012-01-01

As the process of deregulation of electricity and gas markets started in Europe ten years ago, this book aims at recalling and describing the consequences of this evolution, notably for companies which were in a monopoly situation for electricity and gas production, transport, retailing and selling, but also in terms of new entities to be created and of entities having to give up their specialty. The author first presents the economic characteristics of gas and electricity industries in terms of infrastructures and final services, scale, coordination and size of energy networks, of existence of strong externalities in networks, of commitment in public service missions. He describes the background and implementation of this deregulation. He analyses the strategies of companies and how energy markets are controlled: strategies to mitigate competition and to strengthen their market power, firm strategies and public policies, merging strategies, strategies of competition distortion. The last chapter addresses the various priority fields of deregulation: public service missions in a deregulated environment (issues of service continuity and of affordable prices), the environmental constraint in energy market organisation (limitation of CO 2 emissions, promotion of renewable energies, and reduction of energy consumption). In conclusion, the author discusses how to conciliate deregulation and sustainable development of energy

Micro turbines on gas

Microturbines are small gas turbine engines that drive a generator with sizes ranging from 30-350 kW. Although similar in function to bigger gas turbines, their simple radial flow turbine and high-speed generator offer better performance, greater reliability, longer service intervals, reduced maintenance lower emission and lower noise. Microturbines can generate power continuously and very economically to reduce electricity costs or they can be operated selectively for peak shaving. These benefits are further enhanced by the economics of using the microturbine's waste heat for hot water needs or other heating applications. That is why on-site microturbine power is widely used for independent production of electricity and heat in industrial and commercial facilities, hotels, hospitals, office buildings, residential buildings etc. (Original)

The Fast Flux Test Facility (FFTF) is a liquid-metal-cooled test reactor located on the Hanford site. A dual computer system has been developed to monitor the reactor cover gas to detect and characterize any fuel or test pin fission gas releases. The system acquires gamma spectra data, identifies isotopes, calculates specific isotope and overall cover gas activity, presents control room alarms and displays, and records and prints data and analysis reports. The fission gas monitor system makes extensive use of commercially available hardware and software, providing a reliable and easily maintained system. The design provides extensive automation of previous manual operations, reducing the need for operator training and minimizing the potential for operator error. The dual nature of the system allows one monitor to be taken out of service for periodic tests or maintenance without interrupting the overall system functions. A built-in calibrated gamma source can be controlled by the computer, allowing the system to provide rapid system self tests and operational performance reports

The issue of natural gas deregulation has arrived on Canada's east coast

Energy Technology Data Exchange (ETDEWEB)

It is predicted that the introduction of natural gas to Atlantic Canada from Nova Scotia's Sable Offshore Energy Project, will usher in an era of competition among suppliers and choice for customers, making gas deregulation a likely development. Natural gas from the Sable Project is regulated by the National Energy Board for such things as tolls and the cost of transmission through the Maritimes and Northeast Pipeline; residential customer service will be provided by Sempra Atlantic Gas, a provincially regulated distributor which holds the franchise to service the entire province with a gas transportation network. Sempra will provide the infrastructure to move the gas to customers, however, in a deregulated market place customers may choose to purchase gas from a wide range of marketers, producers and brokers, the same way as is now done with home heating fuel. It is expected that several fuel companies will go after the kind of business opportunities that will open up with deregulation, which means that customers will have a choice to buy natural gas from a supplier other than the company that delivers it. The resulting competition among suppliers will translate into savings for the consumer.

Heat-pump-centered integrated community energy systems. System development, Consolidated Natural Gas Service Company, interim report

Heat-pump-centered integrated community energy systems are energy systems for communities that provide heating, cooling, and/or other thermal energy services through the use of heat pumps. Since heat pumps primarily transfer energy from existing and otherwise probably unused sources, rather than convert it from electrical or chemical to thermal form, HP-ICES offer a significant potential for energy savings. Results of the System Development Phase of the HP-ICES Project are given. The heat-actuated (gas) heat-pump incorporated into this HP-ICES concept is under current development and demonstration. The concurrent program was redirected in September 1977 toward large-tonnage applications; it is currently focusing on 60- to 400-ton built-up systems for multi-zone applications. This study evaluates the performance of a HAHP-ICES as applied to a community of residential and commercial buildings. To permit a general assessment of the concept in non-site-specific terms, the sensitivity of the system's performance and economics to climate, community size, utility rate structures, and economic assumptions is explored.

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

Canadian natural gas and climate change

International Nuclear Information System (INIS)

2002-03-01

The Canadian Gas Association (CGA) has expressed concerns regarding how the goal to reduce greenhouse gas emissions can be met. It also has concerns regarding the possible economic impacts of required measures to reduce emissions to 6 per cent below 1990 levels. The CGA argued that since the initial negotiations of the Kyoto Protocol, Canada's greenhouse gas emissions have increased significantly, meaning that if the agreement were to come into force, Canada would have to reduce emissions by about 29 per cent below the currently-projected 2008-2012 level. The report states that 28 per cent of Canada's energy needs are met by natural gas. Excluding energy use in transportation, natural gas contributes more than 40 per cent to Canada's energy portfolio. More than half of Canadian households rely on pipeline services and distribution companies to deliver natural gas for household use. The manufacturing sector relies on natural gas for more than half of its energy needs. Natural gas is a major energy source for the iron/steel, petroleum refining and chemical manufacturing industries. Natural gas is a cleaner-burning fuel than coal or crude oil, and its use results in fewer environmental impacts than other fossil fuels. Vehicles powered by natural gas produce 20 - 30 per cent less carbon dioxide emissions than vehicles powered by gasoline. Pipelines are also a more efficient way of transporting and distributing natural gas than marine transport, railways or trucks. The CGA recommends that policy development should emphasize the environmental benefits of natural gas and recognize its role as a bridge fuel to a cleaner energy-based economy. It also recommends that policies should be developed to encourage the use of natural gas in electricity generation to lower greenhouse gases and air pollutants such as oxides of nitrogen that cause smog

Panel presentation: Impact of combination gas/electric companies on the use of natural gas

International Nuclear Information System (INIS)

Stalon, C.G.

1992-01-01

This paper looks at the advantages and disadvantages of combined gas and electric utilities. It uses a priori reasoning and empirical analysis to present a case that combined utilities actually have the power to do more good for the service area than two separate utilities striving to compete. Unfortunately, the monopoly status of a combined utility may seize the opportunity to maintain the status quo and stop innovation. Based on some simple research, the author found that most combination utilities' electric divisions had higher prices than comparable straight electric utilities, (2) most combination utilities' electric division had higher unit costs than comparable straight electric utilities, and (3) there was no statistical significant difference in price or unit costs between the gas divisions of combination utilities and straight gas utilities. The paper ends with a discussion of policy options and subsequent consequences of preserving the status quo, forced separation of all such combinations, and the review on a case-by-case basis of each combination utility

In the current scenery of natural gas distribution regulation, there is no specific resolution about security. The security is boarded in few concession contracts of some private gas companies, but not as principal theme. The security resolution minute presented in this paper aim break the direct and indirect causes of accidents, eliminating their potential. In this new point of view, the quality of services is the principal cause to guarantee the security of natural gas distribution systems. The methodology used to develop the minute was based on the research of Brazilian and American resolutions of state regulation agencies, concession contracts of private distribution gas companies, American code of federal regulation, ASME code for pressure piping B31.8 - 1999 edition and the NBR 12712 standard. The result of the research was the elaboration of an specific minute resolution of security that can be used as reference in the fiscalization of the natural gas distribution piping companies activities. This minute, can be an important instrument to avoid accidents and incidents, eliminating prejudices to the people, to properties, to environment and to the image of natural gas distribution companies and regulation agencies.

No hesitation: the gas sector of French industry opts for internationalization

International Nuclear Information System (INIS)

Roze, J.

1997-01-01

Since French energy reserves are not big enough, additional energy had to be developed abroad or imported. Using skills acquired on fast-growing markets, the manufacturers of transmission pipelines, equipments, and operating devices have also made a determined turn to external markets. In the business strategy of this sector, internationalization has become deeply rooted because the gas services market is worldwide and the gas applications are being developed around the world. French companies in the gas sector, whether dealing with natural gas or with liquefied petroleum gas, have been able to develop the synergy and partnerships, amongst themselves or with foreign companies, necessary to conquer new markets.

What's ahead for the gas industry?

International Nuclear Information System (INIS)

Rogers, B.

1998-01-01

The issue of what is in store for the North American electricity and gas markets was discussed. The electric power and gas industry are moving towards competition which will benefit the majority of market participants and will create a more level playing field. Deregulation in the U.S. natural gas industry is also building momentum. The steps that companies wishing to be successful must take before they can take full advantage of new and emerging opportunities are to: (1) know their business, and recognize that they are in the energy business, not only in the natural gas or electricity business, (2) organize for success by planning for mergers, acquisitions and alliances, (3) manage for change, and (4) know their markets and customers. Deregulation and converging energies were seen as the two major issues that the energy sector in Canada will be facing in the near future. Natural gas and electric utilities will survive beyond the year 2000 if they are flexible, provide a wide range of services, and offer new rates. Ontario Hydro's move to diversify their existing power generation and to burn natural gas for power generation to meet energy demand was considered to be a good example of how to manage for change. tabs., figs

The quality of the material is up to standard API 5L for Grade B and an automatic-helicoidally welding procedure has been with simultaneous inflow at both internal and and external surfaces. The failure appears together with deformations and fracture. (Author)

Strategies of new-wave energy services companies

International Nuclear Information System (INIS)

Stewart, D.M.G.

1997-01-01

The role of alliances in the new era of energy service companies was discussed. Westcoast Energy Inc. formed an alliance with The Coastal Corporation of Houston to create Engage Energy. Westcoast has also recently joined the Alliance Pipeline project in which a pipeline from British Columbia will interconnect with the North American gas transmission grid. One of the major trends in the energy service industry is deregulation, which is creating competition and providing customers with the ability to choose their suppliers. This open market-based playing field is leading to a convergence of natural gas and electric power industries. Convergence is taking place at a very high pace and is now occurring in financial services, information technology, consumer products and engineering technology. Alliances are also playing a major role in how companies acquire the necessary capabilities to tackle the energy services business. Valuable as they are, alliances can pose challenges to management and can be the source of potential problems. A common vision, similar and realistic expectations, common policy and priorities among the participants, and an effective conflict resolution process are the basic essentials for success. 3 figs

Malin, G. [AltaGas Services Inc., AB (Canada)

2001-07-01

Development of the Ikhil Natural Gas Project by the Inuvialuit Petroleum Corporation in partnership with Enbridge and AltaGas Services are described in a step-by-step fashion. A minimum of 11 Bcf of recoverable natural gas reserves have been established to date. The Northwest Territories Power Corporation is committed under a 15-year take-or-pay contract to take the gas, and the Town of Inuvik also has a franchise agreement with the project owners for a 15-year period. Challenges faced and overcome in adapting to the regulatory process, the engineering problems that required special solutions (e.g. ice/snow roads, gravel pad to support wellhead and production facilities, reducing temperature of gas to avoid disturbing the permafrost, sand-padding pipeline to supplement high ice/content material), converting a diesel town to a natural gas town, and installing an underground distribution system in ground that is constantly shifting due to permafrost, are some of the examples discussed. Benefits accruing to local people and businesses during construction and the production phases of the project are described, along with details of an assessment and discussion of lessons learned after two years of operation. Overall, the project is considered to have been an engineering success. Financially, it is too early to judge, but it is expected that with economic development in Inuvik taking off, demand for natural gas and electricity will develop and justify the confidence of the developers.

Survey of state regulatory activities on least cost planning for gas utilities

International Nuclear Information System (INIS)

Goldman, C.A.; Hopkins, M.E.

1991-04-01

Integrated resource planning involves the creation of a process in which supply-side and demand-side options are integrated to create a resource mix that reliably satisfies customers' short-term and long-term energy service needs at the lowest cost. Incorporating the concept of meeting customer energy service needs entails a recognition that customers' costs must be considered along with the utility's costs in the economic analysis of energy options. As applied to gas utilities, an integrated resource plan seeks to balance cost and reliability, and should not be interpreted simply as the search for lowest commodity costs. All state commissions were surveyed to assess the current status of gas planning and demand-side management and to identify significant regulatory issues faced by commissions during the next several years. The survey was to determine the extent to which they have undertaken least-cost planning for gas utilities. The survey included the following topics: (1) status of state PUC least-cost planning regulations and practices for gas utilities; (2) type and scope ofnatural gas DSM programs in effect, includeing fuel substitution; (3) economic tests and analysis methods used to evaluate DSM programs; (4) relationship between prudence reviews of gas utility purchasing practices and integrated resource planning; and (5) key regulatory issues facing gas utilities during the next five years. 34 refs., 6 figs., 10 tabs

In 1986 it began to speak for the first time of the gas like substitute of the energy in the capital, to toast this way a better energetic option. The business of the gas in Colombia has a great expansion potential, judging by the millionaire transactions that have been carried out recently, in which have participated with signal interest investors of all the continents and it is that the future tendency is the substituting the electric devices for gas devices, at least in that that to cooking of foods and heating of water refers, given the economic and environmental benefits that it represents the overcrowding of the consumption of combustible gases (natural gas and liquefied gas of the petroleum). The economic importance of the investment in the plan of overcrowding of the natural gas in Colombia, represents a very important aspect proposed by the government and of all the actors involved inside the gas industry and it is the one of benefiting economically to the whole community, through the social investment, advanced in each region to or release and wide of the whole country. This promissory panorama for the nascent Colombian gas industry, supported by the discoveries of gas carried out in the decade of the 90, in increasing the reserves of natural gas, to build a great gas pipeline and urban nets, to carry out complementary works and of conversion to gas, to supply thermoelectric that will generate near additional 1500 MW of energy, it also seeks to benefit with the domiciliary gas service, in next four years to more than three million homes distributed in for the less 300 municipalities of the national geography

Gas theft: Prevention and detection

International Nuclear Information System (INIS)

Johnson, G.

1992-01-01

The problem of gas theft is discussed. Roughly 2% of gas and power customers in the United States either steal or attempt to steal service. Most diversion programs focus on theft from a revenue protection viewpoint, however there is often insufficient money recovered to justify an anti-theft program. Successful action often involves focusing on large volume users. Safety should be a prime consideration in searching out gas theft, as many people have been killed or injured as a result of careless theft. A brief review is presented of anti-theft devices such as locks and seals; automated meter reading can also help reduce theft. The best defence against theft is a highly trained and motivated field staff, especially meter readers, and a computer billing program that monitors changes in gas usage. Fixed bypasses may be unlocked and used at will; fraud is also common. Investigation and prosecution should be carried out by trained personnel following a carefully developed procedure. Safety issues should be stressed, and every effort should be made to avoid the appearance that the justice system is being used as a bill collector. 3 refs

We examine the regime governing the gas market in Spain under Law 34/98 of 7 October. The law distinguishes between regulated activities and non-regulated activities. This gives rise to the abandonment by the State of their right to regulate activities related with the gas sector and the opening of said market to free competition. The law privates said activities, through its sets forth that the Sate retains the right and thus must guarantee the supply of gas, as well at sets forth the conditions for rendering such services to individuals. The law also deals with property issues over the networks and the right of third parties to access them; we examine a series of legal explanations concerning these issues. Lastly, the provides that the legal relationship governed by said law changes from a system of State franchise in order to carry on an activity, to a system of prior authorizations subject to a number of ancillary clauses.

Electric utilities and the demand for natural gas

Energy Technology Data Exchange (ETDEWEB)

Uri, N D; Atkinson, S

1976-03-01

The scarcity of natural gas has given rise to a series of priorities of deliveries based on end use and drafted by the Federal Power Commission. The U.S. Supreme Court, on June 7, 1972, held that the Commission has jurisdiction over curtailments in the service of gas in interstate commerce to both resale and direct industrial customers. This decision reversed a Fifth Circuit Court ruling that protected direct industrial customers from curtailments. The FPC priority curtailments are classed from 1 to 9, for which electric utilities are concentrated in classes 4 to 9. As weather conditions become more severe, not only do the residential and commercial consumers demand more electrical energy, they also demand more natural gas. The result is that there is less natural gas available for electric utilities to use for generation so they change to an alternative fuel. A demand model for the short term for natural gas for electric utilities is given; primary factors involve the price of natural gas, the prices of substitute fuels, and the demand for electrical energy by the various consumer classes.

1999-07-01

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

Tight gas sand tax credit yields opportunities

Lewis, F.W.; Osburn, A.S.

1991-01-01

The U.S. Internal Revenue Service on Apr. 1, 1991, released the inflation adjustments used in the calculations of Non-Conventional Fuel Tax Credits for 1990. The inflation adjustment, 1.6730, when applied to the base price of $3/bbl of oil equivalent, adjusts the tax credit to $5.019/bbl for oil and 86.53 cents/MMBTU for gas. The conversion factor for equivalent fuels is 5.8 MMBTU/bbl. Unfortunately, the tax credit for tight formation gas continues to be unadjusted for inflation and remains 52 cents/MMBTU. As many producers are aware, the Omnibus Budget Reconciliation Act of 1990 expanded the dates of eligibility and the usage for-Non-Conventional Fuel Tax Credits. Among other provisions, eligible wells may be placed in service until Jan. 1, 1992, and once in place may utilize the credit for production through Dec. 31, 2002. Both dates are 2 year extensions from previous regulations

Coiled Tube Gas Heaters For Nuclear Gas-Brayton Power Conversion

Energy Technology Data Exchange (ETDEWEB)

Peterson, Per F.

2018-03-31

This project developed an alternative design for heat exchangers for application to heating supercritical carbon dioxide (S-CO₂) or air for power conversion. We have identified an annular coiled tube bundle configuration–where hot sodium enters tubes from multiple vertical inlet manifold pipes, flows in a spiral pattern radially inward and downward, and then exits into an equal number of vertical outlet manifold pipes–as a potentially attractive option. The S-CO₂ gas or air flows radially outward through the tube bundle. Coiled tube gas heaters (CTGHs) are expected to have excellent thermal shock, long-term thermal creep, in-service inspection, and reparability characteristics, compared to alternative options. CTGHs have significant commonality with modern nuclear steam generators. Extensive experience exists with the design, manufacture, operation, in-service inspection and maintenance of nuclear steam generators. The U.S. Nuclear Regulatory Commission also has extensive experience with regulatory guidance documented in NUREG 0800. CTGHs leverage this experience and manufacturing capability. The most important difference between steam generators and gas-Brayton cycles such as the S-CO₂ cycle is that the heat exchangers must operate with counter flow with high effectiveness to minimize the pinch-point temperature difference between the hot liquid coolant and the heated gas. S-CO₂-cycle gas heaters also operate at sufficiently elevated temperatures that time dependent creep is important and allowable stresses are relatively low. Designing heat exchangers to operate in this regime requires configurations that minimize stresses and stress concentrations. The cylindrical tubes and cylindrical manifold pipes used in CTGHs are particularly effective geometries. The first major goal of this research project was to develop and experimentally validate a detailed, 3-D multi-phase (gas-solid-liquid) heat transport model for

Natural gas has become one of the most important energy sources, as we can observe in most countries' energy sector, where its presence is very significant. In Brazil, natural gas corresponds to 7,5% of all energy Also available, and the government has plans to increase this number to 12% until 2010. However, in order to reach this goal, it is important to understand how market works, evaluating all the aspects that have some influence on it. This paper goal is to analyze the natural gas market in Fortaleza metropolitan region, emphasizing the industrial sector, the biggest consumer in Ceara State. The main aspects are characterized here, like professionals qualification in the area, service quality, from equipment and maintenance suppliers until gas distributors, legal aspects, and other factors that are also relevant to a possible future expansion of different natural gas market segments (industry, residence, commerce and transport).

Natural gas poised to penetrate deeper into electric generation

International Nuclear Information System (INIS)

Swanekamp, R.

1995-01-01

This article describes how advancements in gas supply, distribution and storage, coupled with new options in combustion equipment, continue to expand the use of natural gas for electric generation. The challenge is to meet the increasing demand while keeping prices competitive with other fuels--and keep a small band of skeptics at bay. To prepare for the projected growth in gas consumption, the natural-gas industry has invented in new infrastructure and technologies. Pipelines have been built; storage facilities have been expanded; and highly precise flow measurement stations have been installed. To mitigate supply and price risk, suppliers are offering short-, mid-, or long-term contracts which include service options and guarantees. In spite of these preparations, not all power producers are comfortable with the potential tidal wave of gas-fired capacity. Reason: It limits the electric-generation resource base to one fuel for future capacity

1999 Annual report: compression + power + service

International Nuclear Information System (INIS)

2000-01-01

Enerflex manufactures, services and leases compression systems for the production and processing of natural gas and gas-fueled power generation systems. Design, engineering, project management, financing, installation commissioning and after-sales service are also part of Enerflex's arsenal of tools to ensure innovation, and high standards of quality and service. In 1999, Enerflex suffered an 18 per cent decline in revenues from $315 million in 1998 to $257 million in 1999, entirely due to lower sales of big ticket compression equipment in Canada. At the same time, revenues from international sales and service increased to $ 61.8 million in 1999, from $ 53 million in 1998. The company successfully completed the move to a new 328,000 sq. ft state-of-the-art manufacturing facility, and made its first significant sale to the United States in 1999 in the form of delivering a coal bed methane project in the Powder River area of Wyoming, and power generation equipment to Massachusetts. Although in the short term unusually warm average temperatures, industry cash flows, and access to capital may determine demand for the company's products and services, the long-term fundamentals are positive and demand for compression equipment and power generation systems is likely to grow. Indeed, in the fourth quarter of 1999, market conditions improved significantly and the company recorded its highest quarterly revenues and earnings during the last quarter. The annual review provides further details about the operations of the company's various divisions, (Compression and Power Systems, Parts and Compression Services, Leasing and Financing), management's review of the company's overall operations and finances, audited financial statements, and shareholders' information

The pipeline service obligation under changing LDC purchasing practices

International Nuclear Information System (INIS)

Neff, S.J.

1990-01-01

Historically, interstate natural gas pipelines served as aggregators and transporters of gas supplies from the producing fields to the city-gate. In turn, local distribution companies (LDCs) bought gas from pipelines at the city-gate under long-term sales contracts and resold the gas to retail customers. Once a pipeline/LDC sales relationship was established through a regulated certificate process, the LDC was assured of gas supply up to the level of its contract demand (CD) at just and reasonable rates until abandonment of the pipeline's sales service obligation was granted by the Federal Energy Regulatory Commission (FERC). During the years of regulated wellhead pricing and limited gas deliverability, pipelines signed long-term take-or-pay contracts with producers to induce them to develop and commit new gas supplies. Those supply cost obligations were reflected in tariff minimum bill provisions. For years, this pipeline/LDC arrangement was mutually beneficial and provided assured firm service. With the load diversity on large interstate pipeline systems and the make-up provisions under take-or-pay clauses, these gas purchase contracts provided supply reliability without negative economic consequence to the pipelines. Then, with the issuance of FERC Order Nos. 380, 436, and 500, LDCs' obligations to purchase gas from pipeline suppliers according to the terms of those long term sales agreements were irrevocably altered. The impacts of those long term sales agreements were irrevocably altered. The impacts of those orders the elimination of minimum bills and the advent of open access transportation caused a serious erosion of the mutual obligations between pipelines and their LDC customers. The result has been a significant loss of pipeline sales markets as LDC customers have chosen alternative supplied, often at the urging of state public utility commissions (PUCs) to lower short-term costs

Shale Gas Exploration and Development Progress in China and the Way Forward

Chen, Jianghua

2018-02-01

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

Recent developments in the natural gas regulatory arena

Hollis, S.S.

1997-01-01

The changes made by the US Federal Energy Regulatory Commission's (FERC) order no. 636 in traditional trading partner relationships, wherein contracts, not regulators have the most important role in defining the rights between the parties, were discussed. Implications of the unbundling of the natural gas industry were analyzed. While on the whole the policy appears to be a wise one, there are a number of questions yet to be answered about how well customers are served by the policy. The opinion of this author is that for a company to 'take charge of its energy destiny' will involve added costs in terms of having to re-engineer the company's organisation, or having to pay a middleman who is familiar with all the intricacies of gas procurement, trading and transmission. The restructuring of the gas market and the advent of customer oriented service also is driving the next wave of the energy business, namely the provision of integrated services which are the likely consequences of restructuring of the electric industry resulting from FERC orders 888 and 889. The integrated market encouraged by deregulation of the natural gas and electric industries will be one in which sellers will offer all forms of energy from a single source, and a marketplace where different forms of energy can be exchanged or converted. In such a market the role of regulators will be mainly to facilitate competition and to assure a level playing field for all players. 150 refs

Pricing local distribution services in a competitive market

International Nuclear Information System (INIS)

Duann, D.J.

1995-12-01

Unbundling and restructuring of local distribution services is the focus of the natural gas industry. As a result of regulatory reforms, a competitive local distribution market has emerged, and the validity of traditional cost-based regulation is being questioned. One alternative is to completely unbundle local distribution services and transform the local distribution company into a common carrier for intrastate transportation services. Three kinds of alternative pricing mechanisms are examined. For firm intrastate transportation services, cost-based pricing is the preferred method unless it can be shown that a competitive secondary market can be established and maintained. Pricing interruptible transportation capacity is discussed

Designing a blueprint for the future : Canadian Gas Association '98 year in review

International Nuclear Information System (INIS)

1998-01-01

The many initiatives that the Canadian Gas Association (CGA) has taken on behalf of its members in 1998 are summarized. An overview is provided of how the CGA plans to evolve further in response to new issues facing the natural gas sector. The year 1998 was characterised by the restructuring of the Canadian energy marketplace resulting from customer demand for greater value and more choices at lower prices. This led to the unbundling of many products and services traditionally provided by gas distribution utilities and pipeline companies. In 1998, the CGA also promoted the use of natural gas through its Climate Change Task Force, as part of the solution to climate change while giving full value to the significant role played by renewable energy sources. The CGA also spearheaded several initiatives to enhance the safety, reliability and efficiency of the natural gas delivery system. It expanded its website to provide real-time Internet service to better communicate with its members, the media, the general public and government. It commissioned a study to evaluate how economic instruments such as emissions trading, might impact the natural gas industry. The CGA also emerged as a leader in 1998 in dealing with the year 2000 issue. Their Y2K efforts involve all major gas pipelines and local distribution companies

Natural gas and electricity convergence

International Nuclear Information System (INIS)

Calger, C.

1998-01-01

Convergence between the gas and electricity industries was described as a means for creating an increasingly more efficient energy market where prices and fundamental relationships exist between gas and electricity. Convergence creates new opportunities for producers and consumers. Convergence will likely lead to the disaggregation of the electricity and gas industry into segments such as: (1) power generation and production, (2) transmission wires and pipelines, (3) wholesale merchants, (4) distribution wires and pipelines, and (5) retail marketing, services and administration. The de-integration of integrated utilities has already begun in the U.S. energy markets and retail open access is accelerating. This retail competition will create very demanding customers and the changing risk profile will create new issues for stakeholders. The pace of reform for the telecommunications, airlines, natural gas and electricity industries was graphically illustrated to serve as an example of what to expect. The different paths that the industry might take to deregulation (aggressively embrace reform, or defensively blocking it), and the likely consequences of each reaction were also described. A map indicating where U.S. electric and natural gas utility merger and acquisition activities have taken place between 1994-1997, was included. Another map showing the physical asset positions of the Enron grid, one of the largest independent oil and gas companies in the U.S., with increasing international operations, including an electric power transmission and distribution arm, was also provided as an illustration of a fully integrated energy market company of the future. 9 figs

South American natural gas trade: the road ahead

International Nuclear Information System (INIS)

Reinsch, A.E.; Tissot, R.; Peacey, D.

1997-01-01

The current state and future prospects for the natural gas sector in South America were examined, including the ability of the natural gas resource base to meet potential gas demand in the Southern Cone region (Argentina, Bolivia, Brazil, Chile, Paraguay, Peru and Uruguay). The physical, legal, fiscal, regulatory and political developments in the hydrocarbon-producing countries in the Southern Cone region were reviewed. For example, in Colombia, the domestic gas market potential and resource base argue in favor of a closed domestic gas sector development policy. In contrast, Venezuela, a country that already has a well developed domestic gas sector, is pursuing offshore market development through both petrochemical and liquefied natural gas initiatives. Following a comprehensive description of individual gas resources, markets and market potential, and legal, institutional and political environments, the study reports on a number of alternative scenarios concerning natural gas integration in the Southern Cone region, developed by using the South America Natural Gas (SANG) model. The following scenarios were reviewed: (1) closure and confinement, (2) integration and expansion, and (3) gains from technology. It was estimated that potential gas demand in the Southern Cone region is projected to grow from 900 billion cubic feet per year in 1994 to over 5.3 trillion cubic feet in 2021. The majority of growth is expected in Brazil. The overall conclusion of the study was that regardless of the scenario, Southern Core gas sector integration has strong economic and commercial merit, and that the natural gas resource base in the Southern Cone, as represented by the gas reserves database, is more than adequate to service potential demand. 100 refs., 50 tabs., 54 figs

VSAT: opening new horizons to oil and gas explorations

Science.gov (United States)

Al-Dhamen, Muhammad I.

2002-08-01

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

In this paper, the greenhouse gas and energy balances of the production and use for space heating of substitute natural gas from biomass (bio-SNG) for space heat are analysed. These balances are compared to the use of natural gas and solid biomass as wood chips to provide the same service. The reduction of the greenhouse gas emissions (CO{sub 2}-eq.) - carbon dioxide, methane and nitrous oxide - and of the fossil primary energy use is investigated in a life cycle assessment (LCA). This assessment was performed for nine systems for bio-SNG; three types of gasification technologies (O{sub 2}-blown entrained flow, O{sub 2}-blown circulating fluidised bed and air-steam indirect gasification) with three different types of feedstock (forest residues, miscanthus and short rotation forestry). The greenhouse gas analysis shows that forest residues using the air-steam indirect gasification technology result in the lowest greenhouse gas emissions (in CO{sub 2}-eq. 32 kg MWh{sup -1} of heat output). This combination results in 80% reduction of greenhouse gas emissions when compared to natural gas and a 29% reduction of greenhouse gases if the forest residues were converted to wood chips and combusted. The gasification technologies O{sub 2}-blown entrained flow and O{sub 2}-blown circulating fluidised bed gasification have higher greenhouse gas emissions that range between in CO{sub 2}-eq. 41 to 75 kg MWh{sup -1} of heat output depending on the feedstock. When comparing feedstocks in the bio-SNG systems, miscanthus had the highest greenhouse gas emissions bio-SNG systems producing in CO2-eq. 57-75 kg MWh{sup -1} of heat output. Energy analysis shows that the total primary energy use is higher for bio-SNG systems (1.59-2.13 MWh MWh{sup -1} of heat output) than for the reference systems (in 1.37-1.51 MWh MWh{sup -1} of heat output). However, with bio-SNG the fossil primary energy consumption is reduced compared to natural gas. For example, fossil primary energy use is reduced by

Production of inert gas for substitution of a part of the cushion gas trapped in an aquifer underground storage reservoir

International Nuclear Information System (INIS)

Berger, L.; Arnoult, J.P.

1990-01-01

In a natural gas storage reservoir operating over the different seasons, a varying fraction of the injected gas, the cushion gas, remains permanently trapped. This cushion gas may represent more than half the total gas volume, and more than 50% of the initial investment costs for the storage facility. Studies conducted by Gaz de France, backed up by experience acquired over the years, have shown that at least 20% of the cushion gas could be replaced by a less expensive inert gas. Nitrogen, carbon dioxide, or a mixture of the two, satisfy the specifications required for this inert gas. Two main production methods exist: recovery of natural gas combustion products (mixture of 88% N 2 and 12% Co 2 ) and physical separation of air components (more or less pure N 2 , depending on industrial conditions). For the specific needs of Gaz de France, the means of production must be suited to its programme of partial cushion gas substitution. The equipment must satisfy requirements of autonomy, operating flexibility and mobility. Gaz de France has tested two units for recovery of natural gas combustion products. In the first unit, the inert gas is produced in a combustion chamber, treated in a catalytic reactor to reduce nitrogen oxide content and then compressed by gas engine driven compressors. In the second unit, the exhaust gases of the compressor gas engines are collected, treated to eliminate nitrogen oxides and then compressed. The energy balance is improved. A PSA method nitrogen production unit by selective absorption of nitrogen in the air, will be put into service in 1989. The specific features of these two methods and the reasons for choosing them will be reviewed. (author). 1 fig

Applications of UT results to confirm defects findings by utilization of relevant metallurgical investigations techniques on gas/condensate pipeline working in wet sour gas environment

Science.gov (United States)

El-Azhari, O. A.; Gajam, S. Y.

2015-03-01

The gas/condensate pipe line under investigation is a 12 inch diameter, 48 km ASTM, A106 steel pipeline, carrying hydrocarbons containing wet CO2 and H2S.The pipe line had exploded in a region 100m distance from its terminal; after 24 years of service. Hydrogen induced cracking (HIC) and sour gas corrosion were expected due to the presence of wet H2S in the gas analysis. In other areas of pipe line ultrasonic testing was performed to determine whether the pipeline can be re-operated. The results have shown presence of internal planner defects, this was attributed to the existence of either laminations, type II inclusions or some service defects such as HIC and step wise cracking (SWC).Metallurgical investigations were conducted on fractured samples as per NACE standard (TM-0284-84). The obtained results had shown macroscopic cracks in the form of SWC, microstructure of steel had MnS inclusions. Crack sensitivity analyses were calculated and the microhardness testing was conducted. These results had confirmed that the line material was suffering from sour gas deteriorations. This paper correlates the field UT inspection findings with those methods investigated in the laboratory. Based on the results obtained a new HIC resistance material pipeline needs to be selected.

Natural gas production verification tests

International Nuclear Information System (INIS)

1992-02-01

This Environmental Assessment (EA) has been prepared by the Department of Energy (DOE) in compliance with the requirements of the National Environmental Policy Act of 1969. The Department of Energy (DOE) proposes to fund, through a contract with Petroleum Consulting Services, Inc. of Canton, Ohio, the testing of the effectiveness of a non-water based hydraulic fracturing treatment to increase gas recovery from low-pressure, tight, fractured Devonian Shale formations. Although Devonian Shales are found in the Appalachian, Michigan, and Illinois Basins, testing will be done only in the dominant, historical five state area of established production. The objective of this proposed project is to assess the benefits of liquid carbon dioxide (CO 2 )/sand stimulations in the Devonian Shale. In addition, this project would evaluate the potential nondamaging (to the formation) properties of this unique fracturing treatment relative to the clogging or chocking of pores and fractures that act as gas flow paths to the wellbore in the target gas-producing zones of the formation. This liquid CO 2 /sand fracturing process is water-free and is expected to facilitate gas well cleanup, reduce the time required for post-stimulation cleanup, and result in improved production levels in a much shorter time than is currently experienced

This report proposes a multidisciplinary contribution to the debate on shale gas. It first shows that shale gas is already a reality at the international level, that the American economy has improved its competitiveness with direct consequences for the European economy, and notices that some countries which have been reluctant until now, are now evolving. The second part describes the potential of shale gas in France as important but with still uncertain resources. The authors outline that a status-quo would be a threat for the French industry on the short term. Then, the report proposes answers to some questions raised by the exploitation of shale gas in France in terms of risks related to hydraulic fracturing, to water resources, to methane emissions, to organic volatile compounds present in drilling waters, or in terms of noise and visual pollutions. In its last part, the report discusses how to progress in the assessment of the role of shale gas in the French and European energy mix, in the knowledge of the French underground, in the development of shale gas at the service of competitiveness, and with an ensured progressive and controlled evolution

Recent natural gas mergers/alliances and their impact on processing

International Nuclear Information System (INIS)

Kovacs, K.; Schwenker, C.

1997-01-01

Recent mergers and acquisitions have dramatically changed the competitive landscape for companies in the oil, gas and energy services businesses. One measure of this change is the number of publicly traded oil and gas producers in the US. Prior to 1991 the Oil and Gas Journal listed 400 publicly traded producers. This list shrank in 1991 to 300, and as of 1996, the list is now down to 200 in their annual survey. The purpose of this paper is to: briefly review some of the underlying factors or events that have shaped or driven the rush to consolidate; discuss how these changes have impacted gas processing; finally, make some observations on the types of consolidations and opportunities that could occur in the future

As an example of the effectiveness of technical condition service of vibrational methods by expertise fulfillment have been considered for some defects of the overhead pipelines. (author)

Impact of State and Federal regulatory policy on natural gas

International Nuclear Information System (INIS)

Malloy, K.

1992-01-01

This paper presents information which demonstrates the decline in the use and subsequent demand of natural gas as the result of regulatory constraints. These regulations have allowed for a 10 percent decline in the use of natural gas in the last 20 years. The author believes that the major reason for this decline is the existence of State and Federal regulatory requirements which prevent the natural gas industry from effectively responding to new market opportunities. The paper goes on to discuss historical regulations such as the Fuel Use Act and the Natural Gas Policy Act which caused severe impacts to development in the gas industry by placing incremental price controls on natural gas. The author then discusses the effect of deregulation and how it has boosted the gas industry. He specifically discusses the US Canada Free-Trade Agreement and the new negotiations which would greatly enhance the gas sales to Mexico. Finally the author goes on to discuss deregulatory stances proposed as part of the National Energy Strategy regarding natural gas. These include the removal of obstacles to building new pipeline capacities; reformation of rates policies; assurances of nondiscriminatory access to natural gas pipeline services and facilities; and removal of impediments to free and open international trade in natural gas

Solar-assisted gas-energy water-heating feasibility for apartments

Science.gov (United States)

Davis, E. S.

1975-01-01

Studies of residential energy use, solar-energy technology for buildings, and the requirements for implementing technology in the housing industry led to a project to develop a solar water heater for apartments. A design study for a specific apartment was used to establish a solar water-heater cost model which is based on plumbing contractor bids and manufacturer estimates. The cost model was used to size the system to minimize the annualized cost of hot water. The annualized cost of solar-assisted gas-energy water heating is found to be less expensive than electric water heating but more expensive than gas water heating. The feasibility of a natural gas utility supplying the auxiliary fuel is evaluated. It is estimated that gas-utilizing companies will find it profitable to offer solar water heating as part of a total energy service option or on a lease basis when the price of new base-load supplies of natural gas reaches $2.50-$3.00 per million Btu.

The perspectives of development of natural gas for vehicles

International Nuclear Information System (INIS)

Anon.

1996-01-01

This short paper analyses the actions carried out in the world, and in particular in France, to develop and promote the use of natural gas for vehicles (NGV). In France, a protocol of agreement was signed in June 1994 between the French car manufacturers, Gaz de France and the French Association of Natural Gas for Vehicles (AFGNV) in order to develop new kinds of gas fueled vehicles, more optimized engines, to increase the number of gas distribution stations, to ratify the new models of vehicles and the specific parts for these vehicles (composite materials tanks), to carry out R and D work on gas compressors, and to develop public and private fleets of urban buses and public service vehicles. The forthcoming application of the 'Clean Air Law' will support these actions. Significant and similar developments take place also in more than 30 other countries under the same environmental motivation and ambitious programs are planned in the USA, Japan and Argentina for the year 2000. The R and D effort now focusses on the use of LNG instead of compressed natural gas. (J.S.)

Canadian oil and gas survey 1998

Roberge, R.B.

1998-01-01

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

The natural gas industry in Portugal

International Nuclear Information System (INIS)

Kheloufi, S.

2004-01-01

This article makes a synthesis of the evolution of the natural gas sector in Portugal since the end of the 1990's. The aim of the energy policy of Portugal was the creation of a liberalized energy market capable to ensure the security of the energy supplies and to encourage the energy efficiency in order to reduce the environmental impact. The success of the introduction of natural gas in Portugal perfectly fulfills these goals. Since 1997, the natural gas consumption has increased significantly. The start-up of the methane terminal of Sines allows the diversification of the supply sources and contributes to the growth of the offer. The opening of the market is under development. It will allow the main consumers to select their supplier among those present on the Portuguese market. GALP company should keep its leader position and its daughter company 'Gas du Portugal' should reach 300 MW of power generation capacities by 2005 with the development of multi-energy services. The creation of an Iberian energy market between Spain and Portugal should speed up in 2004 leading to deep modifications in the energy sector of southern Europe. (J.S.)

Electric power geneation and other gas market opportunities

International Nuclear Information System (INIS)

Lucy, M.S.

1991-01-01

The future market for natural gas in the northeast USA is discussed. A strong market demand for natural gas is foreseen to continue because of the need for clean burning electric generation facilities and the low saturation of overall natural gas use in the northeast. Although total gas sales increased 30% in the northeast from 1978 to 1989, and conversion of commercial businesses and houses to natural gas use is increasing, the northeast still remains highly dependent on oil as an energy source. For example, nearly 60% of all the oil used to generate electricity and ca 70% of all the home heating oil used the USA is burned in the northeast. The northeast currently receives ca 4.3 billion ft 3 /d of gas, 80% from Louisiana and Texas. With the addition of a number of pipeline projects, another 4.2 billion ft 3 /d will be added by 1992. Power demand is growing, and many New England generation plants are 30 years old or more and in need of upgrading. Natural gas is the fuel of choice for new installations because of pollution regulations, low capital costs, competitive gas pricing, and other factors. A recent report projects that ca 68% of the planned cogeneration capacity in New England will be fuelled by natural gas, requiring an additional 200.7 billion ft 3 /d in the northeast. Another market with strong potential for continued growth is the residential sector, where only 61% of households with gas service use gas for heating. Natural gas vehicle development is being stimulated by mandates for alternative fuelled vehicle fleets; an increase in gas demand of 600 billion ft 3 by 2005 is projectd, based on increased use of natural gas vehicles. 2 figs., 6 tabs

2004-09-30

The ''Enabling & Information Technology To Increase RAM for Advanced Powerplants'' program, by DOE request, has been re-directed, de-scoped to two tasks, shortened to a 2-year period of performance, and refocused to develop, validate and accelerate the commercial use of enabling materials technologies and sensors for Coal IGCC powerplants. The new program has been re-titled as ''Enabling Technology for Monitoring & Predicting Gas Turbine Health & Performance in IGCC Powerplants'' to better match the new scope. This technical progress report summarizes the work accomplished in the reporting period April 1, 2004 to August 31, 2004 on the revised Re-Directed and De-Scoped program activity. The program Tasks are: Task 1--IGCC Environmental Impact on high Temperature Materials: This first materials task has been refocused to address Coal IGCC environmental impacts on high temperature materials use in gas turbines and remains in the program. This task will screen material performance and quantify the effects of high temperature erosion and corrosion of hot gas path materials in Coal IGCC applications. The materials of interest will include those in current service as well as advanced, high-performance alloys and coatings. Task 2--Material In-Service Health Monitoring: This second task develops and demonstrates new sensor technologies to determine the in-service health of advanced technology Coal IGCC powerplants, and remains in the program with a reduced scope. Its focus is now on only two critical sensor need areas for advanced Coal IGCC gas turbines: (1) Fuel Quality Sensor for detection of fuel impurities that could lead to rapid component degradation, and a Fuel Heating Value Sensor to rapidly determine the fuel heating value for more precise control of the gas turbine, and (2) Infra-Red Pyrometer to continuously measure the temperature of gas turbine buckets, nozzles, and combustor hardware.

Techno-Economic Analysis of BEV Service Providers Offering Battery Swapping Services

Energy Technology Data Exchange (ETDEWEB)

Neubauer, J. S.; Pesaran, A.

2013-01-01

Battery electric vehicles (BEVs) offer the potential to reduce both oil imports and greenhouse gas emissions, but high upfront costs, battery-limited vehicle range, and concern over high battery replacement costs may discourage potential buyers. A subscription model in which a service provider owns the battery and supplies access to battery swapping infrastructure could reduce upfront and replacement costs for batteries with a predictable monthly fee, while expanding BEV range. Assessing the costs and benefits of such a proposal are complicated by many factors, including customer drive patterns, the amount of required infrastructure, battery life, etc. The National Renewable Energy Laboratory has applied its Battery Ownership Model to compare the economics and utility of BEV battery swapping service plan options to more traditional direct ownership options. Our evaluation process followed four steps: (1) identifying drive patterns best suited to battery swapping service plans, (2) modeling service usage statistics for the selected drive patterns, (3) calculating the cost-of-service plan options, and (4) evaluating the economics of individual drivers under realistically priced service plans. A service plan option can be more cost-effective than direct ownership for drivers who wish to operate a BEV as their primary vehicle where alternative options for travel beyond the single-charge range are expensive, and a full-coverage-yet-cost-effective regional infrastructure network can be deployed. However, when assumed cost of gasoline, tax structure, and absence of purchase incentives are factored in, our calculations show the service plan BEV is rarely more cost-effective than direct ownership of a conventional vehicle.

Full Text Available This study investigates small-scale variability in ecosystem services and disservices that is important for sustainable planning in urban areas (including suburbs surrounding the urban core. We quantified and valued natural capital (tree and soil carbon stocks ecosystem services (annual tree carbon sequestration and pollutant uptake, and stormwater runoff reduction and disservices (greenhouse gas emissions and soil soluble reactive phosphorus within a 30-hectare heterogeneous green space that included approximately 13% wetland, 13% prairie, 16% forest, and 55% subdivision. We found similar soil organic carbon across green space types, but spatial heterogeneity in other ecosystem services and disservices. The value of forest tree carbon stock was estimated at approximately $10,000 per hectare. Tree carbon sequestration, and pollutant uptake added benefits of $1000+ per hectare per year. Annual per hectare benefits from tree carbon stock and ecosystem services in the subdivision were each 63% of forest values. Total annual greenhouse gas emissions had significant spatial and temporal variation. Soil soluble reactive phosphorus was significantly higher in the wetland than in forest and prairie. Our results have implications for urban planning. Adding or improving ecosystem service provision on small (private or public urban or suburban lots may benefit from careful consideration of small-scale variability.

Greenhouse gas and energy analysis of substitute natural gas from biomass for space heat

International Nuclear Information System (INIS)

Pucker, Johanna; Zwart, Robin; Jungmeier, Gerfried

2012-01-01

In this paper, the greenhouse gas and energy balances of the production and use for space heating of substitute natural gas from biomass (bio-SNG) for space heat are analysed. These balances are compared to the use of natural gas and solid biomass as wood chips to provide the same service. The reduction of the greenhouse gas emissions (CO 2 -eq.) – carbon dioxide, methane and nitrous oxide – and of the fossil primary energy use is investigated in a life cycle assessment (LCA). This assessment was performed for nine systems for bio-SNG; three types of gasification technologies (O 2 -blown entrained flow, O 2 -blown circulating fluidised bed and air–steam indirect gasification) with three different types of feedstock (forest residues, miscanthus and short rotation forestry). The greenhouse gas analysis shows that forest residues using the air–steam indirect gasification technology result in the lowest greenhouse gas emissions (in CO 2 -eq. 32 kg MWh −1 of heat output). This combination results in 80% reduction of greenhouse gas emissions when compared to natural gas and a 29% reduction of greenhouse gases if the forest residues were converted to wood chips and combusted. The gasification technologies O 2 -blown entrained flow and O 2 -blown circulating fluidised bed gasification have higher greenhouse gas emissions that range between in CO 2 -eq. 41 to 75 kg MWh −1 of heat output depending on the feedstock. When comparing feedstocks in the bio-SNG systems, miscanthus had the highest greenhouse gas emissions bio-SNG systems producing in CO 2 -eq. 57–75 kg MWh −1 of heat output. Energy analysis shows that the total primary energy use is higher for bio-SNG systems (1.59–2.13 MWh MWh −1 of heat output) than for the reference systems (in 1.37–1.51 MWh MWh −1 of heat output). However, with bio-SNG the fossil primary energy consumption is reduced compared to natural gas. For example, fossil primary energy use is reduced by 92% when air�

Pressure regulation system for modern gas-filled detectors

International Nuclear Information System (INIS)

McDonald, R.J.

1986-08-01

A gas pressure and flow regulation system has been designed and constructed to service a wide variety of gas-filled detectors which operate at pressures of ∼2 to 1000 Torr and flow rate of ∼5 to 200 standard cubic centimeters per minute (sccm). Pressure regulation is done at the detector input by a pressure transducer linked to a solenoid leak valve via an electronic control system. Gas flow is controlled via a mechanical leak valve at the detector output. Interchangeable transducers, flowmeters, and leak valves allow for different pressure and flow ranges. The differential pressure transducer and control system provide automatic let-up of vacuum chambers to atmospheric pressure while maintaining a controlled overpressure in the detector. The gas system is constructed on a standard 19'' rack-mounted panel from commercially available parts. Five of these systems have been built and are routinely used for both ionization chambers and position-sensitive avalanche detectors

CO2 in Alberta - a vision of the future

International Nuclear Information System (INIS)

Edwards, K.

1999-01-01

The potential to develop a province-wide infrastructure for carbon dioxide (CO 2 ) collection and transmission was discussed. The petroleum industry's original interest in CO 2 was its potential for enhanced oil recovery (EOR) for Alberta's depleted oil fields. However, new interest has stemmed from its perceived role in global climate change and the potentially negative business and economic implications of emitting CO 2 into the atmosphere. It was suggested that the development of a province wide infrastructure to collect CO 2 would address both interests. A simple screening of the reservoirs was carried out to determine if Alberta has the right oil reservoirs and sufficient CO 2 supplies to support a large-scale CO 2 infrastructure. The proposed infrastructure would consist of CO 2 supplies from electrical power generation plants, CO 2 trunklines, feeder pipelines to deliver CO 2 from the trunklines to the field and the oil reservoirs where the CO 2 would be injected. Such infrastructures already exist in Texas and Mexico where more than 1 billion scf per day of CO 2 is used for EOR. This study compared the factors leading to a large-scale CO 2 industry with factors in place during the 1970s and 1980s, when most of the hydrocarbon miscible floods were initiated in Alberta. It was concluded that the preliminary economics suggest that the concept has merit. 12 refs., 3 tabs., 9 figs

Financial instruments help producers hedge gas deals in volatile market

International Nuclear Information System (INIS)

Lawnin, J.N.; Kupiec, S.L.

1993-01-01

The Natural Gas Policy Act (NGPA) of 1978 and more recently the U.S. Federal Energy Regulatory Commission's Order 636 have changed gas marketing from a totally regulated industry to one that responds to free-market forces. The stable but controlled market in which producers once sold gas has become highly competitive and more efficient. Consequently, prices have become more volatile; they respond more quickly than they did before to changes in supply of and demand for natural gas. Prior to deregulation of the natural gas industry, producers had fewer marketing options than they do today. Under a typical gas sales contract, producers sold gas to the nearest pipeline at regulated prices, which remained relatively stable along the interstate distribution chain. The system, however, failed to generate adequate supply of gas. In an effort to realign supply and demand, Congress initiated the deregulation of natural gas with NGPA, which phased out most wellhead price controls. A series of FERC actions culminating in Order 636 extended the process. Now, independent producers can sell gas directly to end users. Under Order 636, interstate pipelines no longer offer merchant services to gas customers. The paper discusses the change in risk profiles, price protection, futures and options, hedged exposure, setting price floors, off-exchange contracts, risk considerations, types of risks, business controls, back office controls, and credit monitoring

Customer service drives pipelines' reorganization

The concept behind formation of Enron Transportation and Storage tells plenty about this new gas industry. When executives at the Enron Gas Pipeline Group considered plans last year to streamline operations by merging the support functions of Transwestern Pipeline and their other wholly owned pipeline company, Northern Natural Gas, seamless customer service was foremost on their agenda. Instead of worrying about whether employees would favor one pipeline over the other, perhaps to the detriment of customers, they simply created a new organization that everyone would swear the same allegiance to. The 17,000-mile, 4.1 Bcf/d Northern system serves the upper Midwest market and two major expansion projects were completed there last year. Transwestern is a 2,700-mile system with an eastward capacity of 1 Bcf/d and westward of 1.5 Bcf/, that traditionally served California markets. It also ties into Texas intrastate markets and, thanks to expansion of the San Juan lateral, to southern Rocky Mountain supplies. Although Enron Corp. continues to position itself as a full-service energy company, the Gas Pipeline Group continues to fuel much of corporate's net income, which was $584 million last year. With ET and S comprising a significant portion of GPG's income, it was vital that the merger of Northern's 950 employees with Transwestern's 250 indeed be a seamless one. It was not easy either psychologically or geographically with main offices in Omaha, NE and Houston as well as operations centers in Minneapolis, MN; Amarillo, TX; W. Des Moines, IA; and Albuquerque, NM. But the results have been gratifying, according to William R. Cordes, President of ET and S and Nancy L.

Biotechnological research has been carried out to find new micro-organisms and processes to make useful products, and to reveal new ways and biotechnological mechanisms to produce elemental sulfur in waste water treatment. Biotechnological development work has been carried out and the first commercial installation (on 300 m{sup 3}/hr scale) to produce sulfur from polluted waste water was started up in 1992. The importance of this recent research and development in the area of waste water treatment was recognized. In an intensive cooperation between Hoogovens Technical Services and PACQUES the concept for a totally new Biological Flue Gas Desulfurization process (BIO-FGD), producing sulfur as by-product, was invented. It consists of the combination of a sodium scrubber with two biological reactors resulting in a very attractive new concept for a gas cleaning process. A description of the process is given and the pilot plant results are outlined. 4 figs., 5 refs.

Debunking the myths: Natural gas and SO2 allowance solutions

International Nuclear Information System (INIS)

Roberts, G.D. Jr.

1993-01-01

During the decade of the 1990's and beyond, natural gas is expected to be the fuel of choice for a significant portion of new generation capacity. Natural gas already enjoys a greater than 50% market share as a fuel source in the non-regulated cogeneration and Independent Power Producer market. With the new administration in Washington, increased environmental focus will likely increase the attractiveness of natural gas based capacity expansions. While these various issues may appear to contribute to making this decade, the decade for natural gas, there are a number of challenges that must be met if the natural gas and power generation industries are going to satisfy the ever increasing needs of the marketplace. These challenges include: (1) myths of natural gas supply availability, (2) transportation and operational coordination issues, (3) uncertainty of price and reliability, and (4) natural gas for NO x and SO 2 compliance. The author believes that these challenges are actively being met and that there are existing solutions already being offered and incorporated into contracts by natural gas suppliers. The focus of this paper is how electric utilities need to become comfortable with the new natural gas industry and how services can be structured to meet these challenges of serving the electric market requirements

The European Market for Seasonal Gas Storage

International Nuclear Information System (INIS)

Mahan, A.

2006-02-01

European demand for gas will grow in the years to come. Simultaneously, gas production in Europe will decrease and imported gas will be needed to replace indigenous production. Gas demand is not constant during the year. There are variations in demand on different timescales ranging from seasonal to hourly. Variations in demand are characterised by two main parameters: working volume and deliverability. Working volume - the amount of gas that can be supplied above the baseload production volume during a long (cold) period- is primarily needed to cope with the summer-winter pattern of gas consumption. Most of the summer-winter pattern comes from the temperature sensitive gas consumption by households and service industries. Gas usage by industry and the power sector are more evenly spread throughout the year and need less working volume. Deliverability - the amount of gas per hour that can be generated on a (very) cold day above the baseload capacity - is the ability to produce large volumes during short periods, e.g. for extremely cold days, or during peak periods during a day. In this paper we argue that a large amount of additional working volume will be required over the coming years. First, flexible European production will be replaced by long-distance import gas, and second, the gas market is expected to grow further. Todays market appears focus mainly on cavems for storage volume. Cavems have little working volume but are ideal for trading purposes. Consequently, Europe may be facing a deficit in working volume, i.e. the ability to cope with seasonal changes in demand. This paper aims to widen the discussion of this matter and give rise to this concern by setting out a broad analysis, exploring the market drivers for seasonal storage and identifying the public interest issues for this market. Chapter 2 gives an overview of demand for and supply characteristics of gas flexibility. Chapter 3 describes the role of gas storage facilities in the gas market

This paper analyzes in extensive detail the user segmentation by vehicle usage, service offering, and full business models from WLAN (Wireless Local Area Network) hot spot services delivered to vehicles (private, professional, public) around gas stations. Also analyzed are the parties which play a role in such service authorization, provisioning and delivery, with all the dependencies modelled by attributed digraphs. Service planning is included as to WLAN base station capabilities. Five year financial models (CAPEX,OPEX), and data pertain to two possible service suppliers: multi-service oil companies, and mobile service operators (or MVNO). Model optimization on the return-on-investment (ROI) is carried out for different deployment scenarios, geographical coverage assumptions, as well as tariff structures. Comparison is also being made with public GPRS data services, as precursors for 3G services, and the effect of WLAN roaming is analyzed. Analysis shows that due to manpower costs and marketing costs, suitable ROI will not be achieved unless externalities are accounted for and innovative tariff structures are introduced. Open issues and further research are outlined. Further work is carried out, also with automotive electronics sector, wireless systems providers, wireless terminals platform suppliers, and vehicle manufacturers

1999-12-31

MCrAlY coatings are widely used on hot section components of gas turbines to provide hot corrosion and/or oxidation protection by formation of an oxide layer on the surface. As the protective oxide scale exfoliates during service, aluminum from the coating diffuses outward for reformation of the protective scale. Aluminum may also diffuse inward due to the differences in composition between the coating and the substrate. Thus, the coatings degrade due to oxidation, oxide scale spallation, and inward and outward diffusion of aluminum. Service life of these coatings is controlled by the aluminum content in the coating, operating temperature and start- shutdown cycles. In-service degradation of CoCrAlY and CoNiCrAlY coatings is presented. A procedure to predict the remaining service life of coatings under oxidizing conditions is discussed. (orig.) 12 refs.

Impact of gas on utilities - competitive energy options

International Nuclear Information System (INIS)

Coolican, M.

1997-01-01

The initiatives taken by Nova Scotia Power to have natural gas as a generating fuel was discussed. Nova Scotia Power customers have indicated to the Utility that along with reduced energy costs, they want choices, better services and innovative products. It was noted that coal is currently Nova Scotia Power's principal fuel, but the utility is working with the Cape Breton Development Corporation, their supplier, to bring the cost of coal down. The utility is also exploring the potential of coal bed methane in Pictou and Cumberland counties of Nova Scotia. However, the most promising competitive energy option for their customers is Sable Offshore natural gas. To bring natural gas as the generating fuel for electricity, the Utility is taking steps to convert its Tufts Cove Thermal Generating Station to natural gas and to pipe natural gas to the Trenton Generating Station by November 1999. Bringing natural gas to these two stations would establish a critical base level of demand for natural gas in the Halifax and New Glasgow-Trenton area. One of the important ingredients of this plan is the cost of piping the gas to market. It was suggested that the 'postage stamp' tolling system (i.e. one price for the gas delivered anywhere along the pipeline) favored by some, would not give Nova Scotians the economic advantages that they deserve. For this reason, Nova Scotia Power favours the 'point to point' tolling system, a system that is considered fair and efficient, and the one that has a better chance of producing competitive energy prices

Fuel cell assembly unit for promoting fluid service and electrical conductivity

Science.gov (United States)

Jones, Daniel O.

1999-01-01

Fluid service and/or electrical conductivity for a fuel cell assembly is promoted. Open-faced flow channel(s) are formed in a flow field plate face, and extend in the flow field plate face between entry and exit fluid manifolds. A resilient gas diffusion layer is located between the flow field plate face and a membrane electrode assembly, fluidly serviced with the open-faced flow channel(s). The resilient gas diffusion layer is restrained against entering the open-faced flow channel(s) under a compressive force applied to the fuel cell assembly. In particular, a first side of a support member abuts the flow field plate face, and a second side of the support member abuts the resilient gas diffusion layer. The support member is formed with a plurality of openings extending between the first and second sides of the support member. In addition, a clamping pressure is maintained for an interface between the resilient gas diffusion layer and a portion of the membrane electrode assembly. Preferably, the support member is spikeless and/or substantially flat. Further, the support member is formed with an electrical path for conducting current between the resilient gas diffusion layer and position(s) on the flow field plate face.

This document reports the contents of contributions and round tables of a meeting which addressed the new usages of gas and their perspectives. An opening contribution notably comments and criticizes how gas was poorly considered in the bill project for energy transition. A first round table addressed the mission of coordination on employment in the LNG sector for transports (presentation, reduction of polluting emissions, European objectives for climate and energy, directive on infrastructures for alternative fuels, advantages of LNG, current situation, LNG development), the role of natural gas and bio-methane (development of natural gas for vehicles or NGV, a lever for development, propositions for a successful transition in transports, perspectives for NGV), the perspectives of development of natural gas in transports, the commitment of Iveco in heavy vehicles with gas engine, the development of a pole for renewable energies in Locmine (Brittany). These issues are then debated. A contribution then proposes an analysis of the challenges faced by energy transition. The second round table addressed the role of the gas sector in energy transition (abundant gas resources, a demand boosted by environmental policies, electricity generation in Europe, gas as the most economic alternative, evolution of gas consumption), the contribution of gas dealers to energy transition, the commitment of energy transport networks (Power to gas), the commitment of the Solvay Energy Services company (an energy trader). These issues are debated. The conclusive contribution is proposed by Mr Gattaz, chairman of the Medef, who addressed the risks and opportunities of energy transition, the assets of France, the advances and matters of worry of the bill project on energy transition, and the essential role of gas in energy transition

Techno-Economic Analysis of BEV Service Providers Offering Battery Swapping Services: Preprint

Energy Technology Data Exchange (ETDEWEB)

Neubauer, J.; Pesaran, A.

2013-03-01

Battery electric vehicles (BEVs) offer the potential to reduce both oil imports and greenhouse gas emissions, but high upfront costs, battery-limited vehicle range, and concern over high battery replacement costs may discourage potential buyers. A subscription model in which a service provider owns the battery and supplies access to battery swapping infrastructure could reduce upfront and replacement costs for batteries with a predictable monthly fee, while expanding BEV range. Assessing the costs and benefits of such a proposal are complicated by many factors, including customer drive patterns, the amount of required infrastructure, battery life, etc. The National Renewable Energy Laboratory has applied its Battery Ownership Model to compare the economics and utility of BEV battery swapping service plan options to more traditional direct ownership options. Our evaluation process followed four steps: (1) identifying drive patterns best suited to battery swapping service plans, (2) modeling service usage statistics for the selected drive patterns, (3) calculating the cost-of-service plan options, and (4) evaluating the economics of individual drivers under realistically priced service plans. A service plan option can be more cost-effective than direct ownership for drivers who wish to operate a BEV as their primary vehicle where alternative options for travel beyond the single-charge range are expensive, and a full-coverage-yet-cost-effective regional infrastructure network can be deployed. However, when assumed cost of gasoline, tax structure, and absence of purchase incentives are factored in, our calculations show the service plan BEV is rarely more cost-effective than direct ownership of a conventional vehicle.

Transitory provisions on public gas distribution in the light of the Marzano law

International Nuclear Information System (INIS)

Vedaschi, Arianna

2005-01-01

The article begins by describing community law on public gas distribution service, then it examines legislative decree 164/2000( also called Letta Decree), which implements directive no. 98/30/CE. This directive reforms the gas sector and in particular it reforms the way gas is distributed. Art. 14 of the Letta Decree states that the distribution of natural gas shall be a public service, contractors shall be selected through a public tender and contracts shall be stipulate for a maximum of 12 years. Thus it is evident that the new model is radically different from the previous one. Before, the service was provided by the local authorities (either directly or through a long-term lease); now the new model aims at liberalizing the market by out sourcing gas distribution. Out sourcing is carried out through a public tender and for short periods of time. In order to allow a gradual transition from the old model to the new one, the Letta Decree provides for a transitory period articulated in various phases. This has the aim of guaranteeing a balance between the interest of local authorities, on one hand and the firms that distributed gas before the reform came into effect, on the other. The first part of the article focuses on interpretative problems that arose after law no. 239/2004 (so called Marzano law) was passed. In the second half it compares the different judicial interpretations concerning: a) duration of the transitory period; b) possibility of increasing duration as provided for by art. 15, par.7 of legislative decree 164/2000; c) efficacy of the abrogation of art. 15, par.8 of legislative decree 164/2000 and finally d) whether advanced redemption of the gas distribution service is still possible. With regards to the transitory period, the article compares judgement no. 111/2005 by the Administrative Tribunal of Lombardia, with judgement no. 6187/2005 delivered by the Sixth Section of the State Council. It then argues that the prohibition of concentration has

The EMS Energy Institute at The Pennsylvania State University (Penn State) has managed the Gas Storage Technology Consortium (GSTC) since its inception in 2003. The GSTC infrastructure provided a means to accomplish industry-driven research and development designed to enhance the operational flexibility and deliverability of the nation's gas storage system, and provide a cost-effective, safe, and reliable supply of natural gas to meet domestic demand. The GSTC received base funding from the U.S. Department of Energy's (DOE) National Energy Technology Laboratory (NETL) Oil & Natural Gas Supply Program. The GSTC base funds were highly leveraged with industry funding for individual projects. Since its inception, the GSTC has engaged 67 members.

Deep water exploration is yielding more than billion barrel oil fields. Unocal's 3 May discovery of 2-3 Tcf of gas in its Kutei block of Indonesia marks the first major discovery of natural gas in the deep water frontier: Wildcats Gula and Gada were drilled in over 1800 m of water as part of an aggressive search for gas instigated by Unocal last year. The author makes a survey of gas exploration and development throughout the world. (author)

Report on the direct purchase of natural gas by non-profit and co-operative housing agencies

International Nuclear Information System (INIS)

1989-06-01

Direct purchase of natural gas is now utilized by many groups of customers in Canada. To date, the process has been effected through short-term contractual arrangements for buying gas from Saskatchewan. Longer-term arrangements (5-15 years) for direct purchase of Saskatchewan or Alberta gas are now being actively considered. There are no longer any real barriers to direct purchase of natural gas for groups of customers in Ontario, but much preparation is required to initiate the process and operate it properly in order to maximize the financial benefits. The various formats for direct purchase (buy/sell, T-service, broker mediated), purchase price considerations, and the benefits and risks of direct purchase are reviewed. Potential savings in gas costs are estimated based on a typical 3-bedroom townhouse family unit and a 1-bedroom senior citizen apartment unit. Generally speaking, it is found possible for the townhouse to save about $50/y on the Consumers Gas and ICG Utilities distribution systems and $34/y for a 1-bedroom apartment suite. An umbrella approach for organizing gas supply contracts is recommended, which allows an agent for the consumer group to enter into a preliminary contract with a gas supplier after completion of a tender process. A number of disciplines are essential for initiation and operation of a direct purchase, requiring the services of four individuals possessing various skills. 5 tabs

Impact of Service Extension and Services Interaction on B2b Sales: A Temporal Investigation Into Fuels’ Category

Directory of Open Access Journals (Sweden)

Marcos Inacio Severo de Almeida

2014-11-01

Full Text Available The scope of services marketing has a theoretical and empirical gap that refers to the impact of the provision of services on sales. This research opportunity is routinely highlighted in theoretical proposals such as the Augmented Service Offering (ASO, Innovation in Services (IS and Service Dominant Logic (SDL, which require alternative measures of combinations of product and service and the possible effects that these arrangements may cause. This article aims to investigate the impact of the extension and the interaction of services on Business to Business (B2B sales. Three hypotheses were tested with data from the fuel sector. Research was operationalized based on secondary data, ceded by an energy company, which comprise sales of regular and premium gasoline of this company to 19 gas stations along 27 months, totaling 513 observations. The study involved the construction of a generalized linear model with balanced, long and random effects panel structure. The three hypotheses were supported, identifying how the extensive principle of service contributes to the increased performance and conclude the existence of a direct, linear and positive impact of extension and interaction of services on B2B sales.

Gill, G. [Emera Energy Inc., Halifax, NS (Canada)

2002-07-01

Emera Energy is a vertically integrated energy company with 4 billion dollars in assets, and one billion dollars in revenue. The ownership structure of Emera Energy was reviewed. The major issues facing Emera Energy all imply a balancing act, between end users and producers, government and industry, infrastructure owners and customers, and Canada versus exports. A brief overview of the regulatory environment in New Brunswick and Nova Scotia was presented. Some of the other issues addressed in this presentation were: project Think, Maritime fragmentation and parochialism, federal/provincial equalization payments, fishing/petroleum industry clash, sovereign risk higher than need be, immature energy industry in Atlantic Canada, and offshore exploration and production industry different than that of the Western Canada Sedimentary Basin (WCSB). National Energy Board (NEB) gas export hearing into the appropriateness of the market oriented export liberalization rules implemented in 1987 for exports of Atlantic Canada gas production is being challenged by the government of New Brunswick. Figures depicting the Canadian gas resource and Nova Scotia offshore gas development were presented, followed by a table providing East Coast offshore costs. The Sable Offshore Energy Project was described, as well as the Deep Panuke gas field. An update on offshore exploration was provided, including comments on onshore activity concerning coal bed methane. A status report of the natural gas supply contracts was discussed. Conventional gas was the next topic discussed, beginning with an overview of onshore activity. The midstream sector was reviewed, with a brief discussion about the existing pipeline system. The mainline expansion plans were reviewed. Some of the gas transmission issues facing the industry in Atlantic Canada are high transport rates, postage stamp toll that is anti-Canadian, gate keeper role for producers, and onerous rules and poor customer service.

Changing incentives for long-term gas contracts

International Nuclear Information System (INIS)

Bohi, D.R.

1992-01-01

There is much concern about the absence of long-term gas contracts with fixed price and quantity conditions, which until recent years was the standard way of doing business in the gas industry. These types of contracts performed a valuable service in the development of the gas industry, and there comparative absence today is sometimes thought to be one reason for the current malaise in the industry. One hears the argument that there must be some kind of 'market failure' that prevents buyers and sellers from entering into these long term arrangements, and recent changes in state and federal regulations are often cited as the cause of the problem. The purpose of the author's remarks is to argue that what is taken as a breakdown in the market may be simply a reaction to a decline in economic incentives to enter into long-term contracts with rigid price and quantity terms. This is, in other words, simply one more aspect of change in the gas business that Frank Heintz referred to in his opening remarks this morning. The author starts by giving a brief description of the motives for engaging in long-term contracts, and then describes how incentives to use long-term contracts have declined for both gas buyers and gas sellers. He concludes that the decline in the use of long-term contracts is not cause for regulatory concern, but a result of the continuing transformation of the gas business to one that more closely resembles other commodity markets

Retrofitting bus fleet for natural gas operation

International Nuclear Information System (INIS)

Stella, E.; Foresti, P.

1992-01-01

Buses, operating within a Florence (Italy) municipal transportation system, and equipped with Otto cycle engines, were selected for retrofitting taking into account the suitability of each vehicle's specific routing and service requirements. Cost benefit analyses indicated that it wouldn't be economically feasible to retrofit buses equipped with diesel engines. A computerized refuelling system was set up at the fleet's central service station which was hooked up to the natural gas utility's supply line. This paper tables the cost benefit analysis data comparing gasoline and methane operation and reflecting the cost savings which are expected to be accrued through this methanization program over a span of 14 years

Corrosion of steels in sour gas environments

International Nuclear Information System (INIS)

Twigg, R.J.

1984-03-01

This report presents a study on the effects of sour gas environments on steels. Emphasis is placed on alloys commonly used in the heavy water, sour gas and refining industries. In addition, 'high strength, low alloy' steels, known as 'oil country tubular goods', are included. Reference is made to the effects of hydrogen sulphide environments on austenitic steels and on certain specialty steels. Theories of hydrogen-related cracking mechanisms are outlined with emphasis placed on sulphide stress cracking and hydrogen induced cracking in carbon and low alloy steels. Methods of controlling sulphide stress cracking and hydrogen induced cracking are addressed separately. Case histories from the heavy water, refining, and sour gas industries are used to illustrate operating experience and failure mechanisms. Finally, recommendations, based largely on the author's industrial experience, are made with respect to quality assurance and inspection requirements for sour service components. Only published literature was surveyed. Abstracts were made of all references, reviewing the major sources in detail

Experimental Evaluation of Cermet Turbine Stator Blades for Use at Elevated Gas Temperatures

Science.gov (United States)

Chiarito, Patrick T.; Johnston, James R.

1959-01-01

The suitability of cermets for turbine stator blades of a modified turbojet engine was determined at an average turbine-inlet-gas temperature of 2000 F. Such an increase in temperature would yield a premium in thrust from a service engine. Because the cermet blades require no cooling, all the available compressor bleed air could be used to cool a turbine made from conventional ductile alloys. Cermet blades were first run in 100-hour endurance tests at normal gas temperatures in order to evaluate two methods for mounting them. The elevated gas-temperature test was then run using the method of support considered best for high-temperature operation. After 52 hours at 2000 F, one of the group of four cermet blades fractured probably because of end loads resulting from thermal distortion of the spacer band of the nozzle diaphragm. Improved design of a service engine would preclude this cause of premature failure.

Air and gas cleaning technology for nuclear applications

International Nuclear Information System (INIS)

First, M.W.

1986-01-01

All large-scale uses of radioactive materials require rigid control of off-gases and generated aerosols. Nuclear air and gas cleaning technology has answered the need from the days of the Manhattan Project to the present with a variety of devices. The one with the longest and most noteworthy service is the HEPA (high efficiency particulate air) filter that originally was referred to as an absolute filter in recognition of its extraordinary particle retention characteristics. Activated-charcoal adsorbers have been employed worldwide for retention of volatile radioiodine in molecular and combined forms and, less frequently, for retention of radioactive noble gases. HEPA filters and activated -charcoal adsorbers are often used with auxiliary devices that serve to extend their effective service life or significantly improve collection efficiency under unfavorable operating conditions. Use of both air cleaning devices and their auxiliaries figure prominently in atomic energy, disposal of high- and low-level nuclear wastes, and in the production of fissile materials. The peaceful uses of nuclear energy would be impossible without these, or equivalent, air- and gas-cleaning devices

ICT and greenhouse gas emissions; IKT og klimagassutslipp

Energy Technology Data Exchange (ETDEWEB)

2009-08-15

ICT can go from being a part of the climate challenge to be an important part of the solution by simplify, rationalize and replace a variety of features and services. ICT's contribute through production and operation for approx. 2.5 % of global greenhouse gas emissions. At the same time estimates show that ICT could help to reduce total greenhouse gas emissions by up to 15 % by 2020 through a series of measures. ICT can, for example. contribute to reduce travel activity through remote collaboration, the transition from material to virtual products and by greater energy efficiency in buildings and vehicles. Through remote collaboration, green tender rounds and change of focus from products to services, can authorities reduce their own emissions. In addition, the authorities go ahead as good examples by illustrating how environment benefits from governmental ICT investments. If we assume that video conferencing can replace 1 of 5 flights among the 140 000 state employees, this can lead to a reducted emission of 14 600 tonnes of CO{sub 2} per year. (AG)

Qiu, Yu

2004-08-01

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

Natural gas: An essential source of energy in the Romanian economy

International Nuclear Information System (INIS)

Coconea, G.

1993-01-01

The Romanian natural gas industry has existed since the early 1900s. The share of natural gas in Romania's current energy consumption is around 40%. The state gas company Romgaz operates ca 150 gas fields and 3,600 producing wells, but only 20% of annual production is being replaced by new discoveries. Declining gas production is caused by such factors as improper well completion, delayed workovers, water encroachment, and sand consolidation. Romgaz also transports imported natural gas from Russia and provides transportation services to natural gas importers in neighboring countries. The gas transmission network comprises ca 11,000 km of pipelines and 82,800 kW of installed compressor capacity. The distribution system supplies gas to over 2.5 million customers over some 15,000 km of pipeline. Future projects include expansion of production and increasing recoverable reserves, modernization of equipment, constructing an interconnecting pipeline with the Ukraine, installing a liquefied natural gas terminal on the Black Sea, rehabilitating the gas transmission grid, and installing supervisory control and data acquisition systems. The gas consumption pattern of 1990 (57% industrial, 31% power generation, 8% households) is expected to change with a substantial increase in household and commercial supplies, as well as replacement of gas-fired generation with hydroelectric and nuclear generation. A governmental restructuring strategy is being implemented to enhance oil and gas production, to improve operational efficiency of the sector, and to address environmental pollution. Components of the strategy are outlined

[Natural gas rate design and transportation issues

International Nuclear Information System (INIS)

Howard, G.S.

1992-01-01

This paper is presented from an industrial user viewpoint with regards to natural gas distribution and pricing. The author reviews the problems with rate structures at local distributing companies and gas utility companies which resort to charging high prices to industrial users while subsidizing residential users. He goes on then to discuss the lack of innovation amount LDCs to meet the needs of the industrial sector. Secondly it analyses the regulation and price structure of the pipeline industry which drastically affects all gas prices. The paper specifically discusses 'equivalent margin rates' which are being used by many states to control transportation rates. The author feels that these margin rates are inappropriate in that it transfers much of the LDC's exploration and development costs to the pipeline company which transfers it on to the consumer. He feels that the transportation rates should exclude all costs that are clearly not incurred by an LDC to provide transportation service. The paper concludes with recommendations to regulators regarding the need for regulatory reform of deregulation of the gas industry with regards to profit-taking and the transportation industry with regards to developing capacity assignment programs

The approach of NOVA Gas International Ltd. (NGI) to locating international development opportunities was reviewed. NOVA has provided consulting expertise to more than 300 projects in 50 countries during the past 20 years. NGI is focusing its energies on five regions: Canada, the US, Mexico, the southern cone of South America and the Asia-Pacific region. To determine where to offer natural gas services and petrochemicals, the Company utilizes a multi-step analysis process which is designed to identify (1) the perfect customer, (2) the most attractive global regions, (3) the potential pitfalls, and (4) the best projects. NOVA also found out the importance of developing a solid network of local contacts and partners. Project financing must be adequate and flexible, requiring constant communications with partners and interested parties

A comparative study of gas-gas miscibility processes in underground gas storage reservoirs

Energy Technology Data Exchange (ETDEWEB)

Rafiee, M.M.; Schmitz, S. [DBI - Gastechnologisches Institut gGmbH, Freiberg (Germany)

2013-08-01

Intermixture of gases in underground gas reservoirs have had great weight for natural gas storage in UGS projects with substitution of cushion gas by inert gases or changing the stored gas quality or origin, as for the replacement of town gas by natural gas. It was also investigated during the last years for Enhanced Gas Recovery (EGR) and Carbon Capture and Storage (CCS) projects. The actual importance of its mechanisms is discussed for the H{sub 2} storage in Power to Gas to Power projects (PGP). In these approaches miscibility of the injected gas with the gas in place in the reservoir plays an important role in the displacement process. The conditions and parameters for the gas-gas displacement and mixing have been investigated in previous projects, as e.g. the miscibility of CO{sub 2} with natural gas (CLEAN). Furthermore the miscibility process of town gas with natural gas and sauer gas with sweet gas were also previously measured and compared in laboratory. The objective of this work is to investigate the miscibility of H{sub 2} injection into natural gas reservoirs using a compositional and a black oil reservoir simulator. Three processes of convection, dispersion and diffusion are considered precisely. The effect of gas miscibility is studied for both simulators and the results are compared to find optimum miscibility parameters. The findings of this work could be helpful for further pilot and field case studies to predict and monitor the changes in gas composition and quality. In future this monitoring might become more important when PGP together with H{sub 2}-UGS, as storage technology, will help to successfully implement the change to an energy supply from more renewable sources. Similarly the method confirms the use of the black oil simulator as an alternative for gas-gas displacement and sequestration reservoir simulation in comparison to the compositional simulator.

De Silva, P.N.K.; Simons, S.J.R.; Stevens, P.

2016-01-01

In the US, the shale gas revolution ensured that the development costs of unconventional natural gas plummeted to the levels of $2–3/Mcf. This success has motivated the development of shale gas in other regions, including Australia and Europe. This study, focussing primarily on aspects of economic impact analysis, estimates the development costs of shale gas extraction in both Australia and Europe, based on both direct and fiscal costs, and also suggests policy initiatives. The increasing liquefied natural gas (LNG) developments in Australia are already straining domestic gas supplies. Hence, the development of more natural gas resources has been given a high priority. However, a majority of the Australian shale resources is non-marine in origin and significantly different to the marine-type shales in the US. In addition, the challenges of high development costs and the lack of infrastructure, service capacity and effective government policy are inhibiting shale gas development. Increasing the attractiveness of low risk investment by new, local, developers is critical for Australian shale gas success, which will simultaneously increase domestic gas security. In the European context, unconventional gas development will be challenged by direct, rather than fiscal costs. High direct costs will translate into average overall gas development costs over $13/Mcf, which is well over the existing market price. - Highlights: • The shale gas development potential of US, Europe and Australia are compared. • An economic impact analysis of shale gas development in Europe and Australia. • Factors important for shale gas development are discussed. • Policy pathways are suggested for shale gas development

British Gas plans global gas unit expansion

Vielvoye, R.

1991-01-01

This paper reports on developing a global gas business, a British Gas plc's strategy for evolving a state owned U.K. gas company to a privatized worldwide oil and gas giant. By 2000, BG's global gas business is expected to provide 20% of its revenues, compared with 40% each from its exploration and production operations and its U.K. gas business. The global gas unit (GGU) plans to meet its targets mainly through acquiring holdings in gas transmission and distribution companies around the world. In the 12 months since GGU was established, it has made two such major acquisitions in this area. BG acquired Consumers Gas Co., Ltd., Ontario, Canada's biggest natural gas distribution company, for $943.5 million. It also took a 10% stake in Catalana de Gas SA, Barcelona, the largest privately owned gas utility in Spain and in terms of number of customers, the fourth largest in western Europe. BG also is targeting additional revenues from developing gas fired cogeneration systems in developing countries with gas reserves but no established transmission and distribution systems
