Natural gas projects in the developing world: An empirical evaluation of merits, obstacles, and risks

Science.gov (United States)

Mor, Amit

Significant amounts of natural gas have been discovered in developing countries throughout the years during the course of oil exploration. The vast majority of these resources have not been utilized. Some developing countries may benefit from a carefully planned utilization of their indigenous resources, which can either be exported or used domestically to substitute imported or exportable fuels or feedstock. Governments, potential private sector investors, and financiers have been searching for strategies to promote natural gas schemes, some of which have been in the pipeline for more than two decades. The purpose of this thesis is to identify the crucial factors determining the success or failure of launching natural gas projects in the developing world. The methodology used to evaluate these questions included: (1) establishing a representative sample of natural gas projects in developing countries that were either implemented or failed to materialize during the 1980-1995 period, (2) utilizing a Probit limited dependent variable econometric model in which the explained variable is project success or failure, and (3) choosing representing indicators to reflect the assumed factors affecting project success. The study identified two conditions for project success: (1) the economic viability of the project and (2) securing financing for the investment. The factors that explain the ability or inability of the sponsors to secure financing were: (1) the volume of investment that represented the large capital costs of gas transportation, distribution, and storage, (2) the level of foreign exchange constraint in the host country, and (3) the level of development of the country. The conditions for private sector participation in natural gas projects in developing countries were identified in the study by a Probit model in which the explained variable was private sector participation. The results showed that a critical condition for private sector participation is the

In February 1990, General Electric Capital Corporation (GECC), through its wholly owned subsidiary, General Electric Power Funding Corporation (GEPFC), provided a number of commitments to a partnership (the Partnership) formed by a company that develops, owns, and operates cogeneration facilities to fund the development, construction, and permanent debt and equity financing of a 614 megawatt (M) cogeneration facility (the Project) to be located near a large refinery in the northeastern United States. The Project is unusual both for the magnitude of its natural gas requirements and for its contractual configuration. The Project's entire transportation needs and a substantial portion of its gas requirements will be met by a joint venture between two local gas distribution companies (the Joint Venture), one of which is a large gas-consuming utility in the eastern United States. The Project's power purchase customer, (the Utility Host), is another very large gas-consuming utility. Thus, the fuel cost recovery of the Project is determined by the Utility Host's gas costs while its actual bill for fuel will be heavily influenced by the Joint Venture's gas commodity and transportation costs. Therefore, in appraising the credit quality of the Project's proposed fuel supply arrangements, the key issue to be answered is: Are the Project's natural gas supply and transportation arrangements compatible with the fuel cost recovery provisions of the power sales agreement with the Utility Host? If so, then the sensitivity of the Project's financing to adverse gas price movements would be minimized

DME can be manufactured from such raw materials as natural gas, coal bed gas and coal. NKK who is developing a technology to synthesize efficiently the DME being a new energy has been commissioned from NEDO to investigate and study a project to manufacture DME using natural gas produced in Sinchuan Province, and utilize it as fuel for power generation, transportation and LPG substitution. In the present research, the DME manufacturing plant size was assumed to be 500 tons a day (165 x 10{sup 3} tons annually). This output nearly corresponds to the current LPG consumption. The required amount of natural gas as the raw material is 0.2 x 10{sup 9} Nm{sup 3}/year, wherein, since the total production quantity of natural gas in Sinchuan Province is 10 x 10{sup 9} Nm{sup 3}/year, there is no problem in the supply of natural gas as the raw material. The construction cost was estimated to be 11 billion yen taking into consideration the device fabrication cost and construction labor cost in China. Furthermore, as a result of discussing the economy considering the natural gas material cost, industrial water cost, and labor cost for plant operation, the internal profit rate for the total capital after tax was found a little over 10%, proving the project to have excellent economic performance.

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

Natural gas consumption in the US grew 15.9 percent between 1986 and 1989. Its share of total primary energy use in the US grew from 22.5 percent to 23.8 percent. Despite unusually warm weather and an economic downturn, natural gas use in the first eight months of 1990 fell only modestly from its 1989 pace - while its market share of US total primary energy use has remained stable. The American Gas Association's Total Energy Resource Analysis energy modeling system (A.G.A.-TERA) projects continued growth in natural gas demand and supply. Natural gas is projected to gain a growing share of total US primary use. Natural gas prices are projected to be sufficient to encourage growth in well completions and reserve additions, yet competitive with electricity, fuel oil and other alternative forms of energy

2010-12-15

Due to the increasing European import dependency, significant additional natural gas volumes will be required. In addition to the Nord Stream pipeline, the Nabucco and South Stream pipeline are projects planned for the next decade to provide further gas supplies to the European market. As one of the European Union's energy policies' foci is security of supply, the question can be raised if and how these projects contribute to this objective not only in terms of diversification but also in case of supply disruptions such as occurred in 2009 during the Russia-Ukraine gas crisis. This paper discusses the impact of these two major gas import pipeline projects on the South-Eastern Europe gas supply and analyzes their effects on gas flows and marginal cost prices in general and in case of gas supply disruptions via Ukraine in a model-based analysis with the European natural gas infrastructure and dispatch model TIGER.

Worldwide natural gas is forecasted to be the fastest growing primary energy source. In Egypt, natural gas is recently playing a key role as one of the major energy sources. This is supported by adequate gas reserves, booming gas industry, and unique geographical location. Egypt's current proven gas reserves accounted for about 62 TCF, in addition to about 100 TCF as probable gas reserves. As a result, it was decided to enter the gas exporting market, where gas is transported through pipelines as in the Arab Gas pipelines project and as a liquid through the liquefied natural gas (LNG) projects in Damietta, and ld ku. With the start up of these currently implemented LNG projects that are dealing with the very low temperatures (down to -162 degree c), the gas has to be subjected to a regular analysis in order to check the compliance with the required specifications. Mercury is a trace component of all fossil fuels including natural gas, condensates, crude oil, coal, tar sands, and other bitumens. The use of fossil hydrocarbons as fuels provides the main opportunity for emissions of mercury they contain to the atmospheric environment: while other traces exist in production, transportation and processing systems

The growth of the international natural gas trade during the last decade resulted in the expectation that this product would be traded as a commodity. This expectation created a boom in the investments related to the commercialization of natural gas between borders, especially in the distinct segments of the chain of liquefied natural gas (LNG). Different agents launched themselves into liquefaction and regasification enterprises, and the ordering of ships also showed significant growth. Despite that, the natural gas market still cannot be considered global, and international gas transactions are primarily done within regional markets. This article investigates the challenges posed to the constitution of a global natural gas market. These challenges represent risks to the commercialization of this product in spot bases, for the agents that launch themselves into projects to export or import LNG to be commercialized through short term contracts in the international market for this product.

This presentation was given by leading energy analysts Pervin and Gertz, and provided their outlook on the North American natural gas supply and demand as well as transportation and processing options for the Mackenzie Valley project and the Alaska natural gas project. Arctic gas development was discussed in relation to larger North American and world energy markets. The impacts of liquefied natural gas (LNG) infrastructure development were compared with the potential impacts of the Alaska and Mackenzie Valley pipelines. A review of North American gas supplies was presented. LNG imports to the United States are expected to exceed 8 BCF/D by 2010. In addition, huge growth in the LNG markets is expected in middle eastern countries as well as in Africa. There is currently strong growth in liquefaction capacity in most regions. However, many proposed LNG terminals will not proceed due to opposition on the west coast of North America. It is also expected that natural gas liquids (NGL) delivered to Alberta from the Mackenzie Valley Gas project are expected to be used by the heavy oil industry. Canadian crude supplies are expected to grow to nearly 4 million barrels per day by 2015. The impacts of Alaska and Mackenzie Valley gas projects on western NGL markets and the petrochemicals industry were reviewed. It was concluded that major investments in supply and infrastructure are need in order to develop Arctic gas, as LNG is likely to be the largest source of incremental supply. tabs., figs

Natural gas demand prospects in Korea

Korea s natural gas demand has increase enormously since 1986. Natural gas demand in Korea will approach to 29 million tonnes by the year 2010, from little over 9 million tonnes in 1996. This rapid expansion of natural gas demand is largely due to regulations for environmental protection by the government as well as consumers preference to natural gas over other sources of energy. Especially industrial use of gas will expand faster than other use of gas, although it will not be as high as that in European and North America countries. To meet the enormous increase in demand, Korean government and Korea Gas Corporation (KOGAS) are undertaking expansion of capacities of natural gas supply facilities, and are seeking diversification of import sources, including participation in major gas projects, to secure the import sources on more reliable grounds.

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

Deliverability was projected under the following 3 scenarios to reflect varying levels of drilling investment that may occur: (1) a reference case; (2) a high case; and (3) a low case. Canadian natural gas has provided approximately 25 per cent of North America's natural gas production over the past few years. Marketable gas sales in 2006 were approximately $42 billion. Approximately 98 per cent of the total Canadian volume of natural gas is produced in the western Canadian sedimentary basin (WCSB). Results of the scenario analyses showed that deliverability decreased in all 3 projected scenarios. By 2009, Canadian natural gas deliverability was projected to decrease to between 410 and 449 million m 3 /d. The report also noted that the annual decline rate of the average natural gas well is 55 per cent. Producers have been maintaining deliverability by increasing the number of wells drilled annually. Gas producers are now targeting the western side of the basin, and are drilling deeper wells in order to access richer deposits of gas. Coalbed methane (CBM) production is also expected to increase over the next few years. It was concluded that Canadian deliverability will continue to play an important role in North American gas supplies. 6 tabs., 6 figs

Natural gas supply in Denmark - A model of natural gas transmission and the liberalized gas market

International Nuclear Information System (INIS)

Bregnbaek, L.

2005-01-01

In the wake of the liberalization of European energy markets a large area of research has spawned. This area includes the development of mathematical models to analyze the impact of liberalization with respect to efficiency, supply security and environment, to name but a few subjects. This project describes the development of such a model. In Denmark the parallel liberalization of the markets of natural gas and electricity and the existence of an abundance of de-centralized combined heat and power generators of which most are natural gas fired, leads to the natural assumption that the future holds a greater deal of interdependency for these markets. A model is developed describing network flows in the natural gas transmission system, the main arteries of natural gas supply, from a technical viewpoint. This yields a technical bounding on the supply available in different parts of the country. Additionally the economic structure of the Danish natural gas market is formulated mathematically giving a description of the transmission, distribution and storage options available to the market. The supply and demand of natural gas is put into a partial equilibrium context by integrating the developed model with the Balmorel model, which describes the markets for electricity and district heat. Specifically on the demand side the consumption of natural gas for heat and power generation is emphasized. General results and three demonstration cases are presented to illustrate how the developed model can be used to analyze various energy policy issues, and to disclose the strengths and weaknesses in the formulation.

Oman, currently seeking to diversify its hydrocarbon industry, away from dependence on oil, is currently planning to exploit its huge reserves of natural gas. Three projects are described. The first involves the construction of a regional gasline to the emirate of Ras al-Khaimah. The second two projects are export based. The first entails producing liquefied natural gas (LNG) for export by sea to markets in the Far East. The last project includes pumping natural gas to India via a marine pipeline through the Arabian Sea. (UK)

Australia is re-launching its ambitions in liquefied natural gas (LNG) with the Greater Gorgon project of offshore exploitation of the natural gas reserves of the continental shelf of NW Australia. These reserves would represent 200 million tons of LNG which will be exported towards China and USA. The project will cost 11 billion dollars and will yield 2 billion dollars per year. It is managed by a consortium which groups together Chevron Corp. (50%), Shell (25%) and ExxonMobil (25%). Technip company is partner of the project. The China National Offshore Oil Corp (CNOOC) has announced its intention to become also partner of the project, and maybe Japan, South Korea and Taiwan will wish too. Short paper. (J.S.)

Gas expanders at M/R Stations in the natural gas distribution network. Pre-project, subreport; Gasexpandere paa distributionsnettets M/R-stationer. Forprojekt, delrapport

Danish Gas Technology Centre has been carrying out a feasibility project to clarify the possibilities of installing gas expanders at M/R-stations (Measuring and Regulating) in the Distribution system of the natural gas grid. A large number of such expanders are installed around the world. The novelty of this project is to use a heat pump to perform the necessary heating of the gas before the expander, and to ''export'' to the electricity grid the remaining electricity from the generator connected to the expander. The present project includes the small M/R-stations at the gas Distribution grid where pressure is reduced from 40 or 20 bar to 4 bar. The preliminary project (year 1 of project) has investigated whether components for such smaller systems can be found, and it has investigated prices for different quantities. A technical feasibility study has been done. Also, preliminary calculations of payback times has been carried out. A large potential of CO{sub 2}-reduction is present with this technology based on saving of natural gas combustion and on new electricity production displacing existing production without any use of primary energy. The main results and conclusions are: 1) There are component suppliers for expander systems suitable to the size of distribution network M/R stations. 2) Pressure regulators provided at the stations are laid out with significant overcapacity, enabling a simplified installation of the expander systems. 3) If the system is being rolled out across the Danish distribution grid, the realistic saving potential is approx. 2.3 million Nm3 of gas per year and a production of almost 40 million kWh of electricity. 4) If the price is 0.60 DKK/kWh for electricity sold, the simple pay-back is 6-7 years on average, covering a variation from 3 to 16 years at the various stations. The smallest stations are omitted. The best stations covering more than half of the gas flow have a pay-back time between 3 and 6 years. 5) The

Natural gas is swiftly moving from a locally traded commodity in regional markets to a globally traded commodity. This paper describes a numerical model of international gas trade which evaluates the effects of inter- and intra-regional gas trade on demand, supply and price. Preliminary evidence indicates natural gas prices are 15 to 30% lower in real terms when inter-regional trade occurs and local consumption of natural gas increases relative to fuel oil in the local market. Natural gas developers or marketers that explicitly consider the inter-regional impacts of gas trade will have a greater likelihood of understanding the risks in marginal projects and are more likely to embrace economic projects and eschew noneconomic projects

Venezuela natural gas outlook

Silva, P.

1991-01-01

This paper reports on the natural gas outlook for Venezuela. First of all, it is very important to remember that in the last few years we have had frequent and unforeseen changes in the energy, ecological, geopolitical and economical fields which explain why all the projections of demand and prices for hydrocarbons and their products have failed to predict what later would happen in the market. Natural gas, with its recognized advantages over other traditional competitors such as oil, coal and nuclear energy, is identified as the component that is acquiring more weight in the energy equation, with a strengthening projection, not only as a resource that covers demand but as a key element in the international energy business. In fact, natural gas satisfies 21% of overall worldwide energy consumption, with an annual increase of 2.7% over the last few years, which is higher than the global energy growth of other fossil fuels. This tendency, which dates from the beginning of the 1980's, will continue with a possibility of increasing over the coming years. Under a foreseeable scenario, it is estimated that worldwide use of natural gas will increase 40% over the next 10 years and 75% on a longer term. Specifically for liquid methane (LNG), use should increase 60% during this last decade. The LPG increase should be moderate due to the limited demand until 1995 and to the stable trends that will continue its use until the end of this century

Product and strategic analysis at the Department of Energy (DOE)/Morgantown Energy Technology Center (METC) crosscuts all sectors of the natural gas industry. This includes the supply, transportation, and end-use sectors of the natural-gas market. Projects in the Natural Gas Resource and Extraction supply program have been integrated into a new product focus. Product development facilitates commercialization and technology transfer through DOE/industry cost-shared research, development, and demonstration (RD&D). Four products under the Resource and Extraction program include Resource and Reserves; Low Permeability Formations; Drilling, Completion, and Stimulation: and Natural Gas Upgrading. Engineering process analyses have been performed for the Slant Hole Completion Test project. These analyses focused on evaluation of horizontal-well recovery potential and applications of slant-hole technology. Figures 2 and 3 depict slant-well in situ stress conditions and hydraulic fracture configurations. Figure 4 presents Paludal Formation coal-gas production curves used to optimize the hydraulic fracture design for the slant well. Economic analyses have utilized data generated from vertical test wells to evaluate the profitability of horizontal technology for low-permeability formations in Yuma County, Colorado, and Maverick County, Texas.

Minas Gerais is a State where there is no production of natural gas. Aiming to increase the consumption of natural gas in Minas Gerais, PETROBRAS increase the network of gas natural distribution in the State of Minas Gerais and the State concessionaire (GASMIG) installed the Project of Natural Gas Valley. The case study is associated to an enterprise that firmed contract for supplying of natural gas. The fuel to be substituted is the Liquefied Petroleum Gas and the results of the substitution were shown. The advantages of the substitution were related to costs, and environmental aspects with the reduction of CO{sub 2} production. The natural gas contains a lower content of impurities and is operated with higher safety than the petroleum liquefied gas. (author)

Risks in the transport and storage of liquefied natural gas. Sub-project 5-2: Investigation into building damage

Science.gov (United States)

Gouwens, C.; Dragosavic, M.

The large reserves and increasing use of natural gas as a source of energy have resulted in its storage and transport becoming an urgent problem. Since a liquid of the same mass occupies only a fraction of the volume of a gas, it is economical to store natural gas as a liquid. Liquefied natural gas is stored in insulated tanks and also carried by ship at a temperature of -160 C to 170 C. If a serious accident allows the LNG to escape, a gas cloud forms. The results of a possible explosion from such a gas cloud are studied. The development of a leak, escape and evaporation, size and propagation of the gas cloud, the explosive pressures to be expected and the results on the environment are investigated. Damage to buildings is examined making use of the preliminary conclusions of the other sub-projects and especially the explosive pressures.

Natural gas : a highly lucrative commodity

Exploration and production of natural gas has become highly profitable as natural gas is becoming a leading future commodity. With new technology, high demand and environmental benefits, natural gas is the preferred choice over petroleum as the leading source of energy to heat home and businesses. Canada is the world's third largest producer of natural gas with its Sable Offshore Energy Project being the fourth largest producing natural gas basin in North America. The basin will produce high quality sweet natural gas from 28 production wells over the course of the next 20 to 25 years. The gas will be transported to markets through Nova Scotia, New Brunswick and into the Northeastern United States via the Maritimes and Northeast Pipeline. The 1051 kilometer underground gas pipeline is currently running laterals to Halifax, Nova Scotia and Saint John, New Brunswick. Market studies are being conducted to determine if additional lines are needed to serve Cape Breton, Prince Edward Island and northern New Brunswick. A recent survey identified the following 5 reasons to convert to natural gas: (1) it is safe, (2) it is reliable, (3) it is easy to use, (4) it is cleaner burning and environmentally friendly compared to other energy sources, and (5) it saves the consumer money

Interest in Natural Gas in Brazil emerged in the second half of the twentieth century, against a background in which the global giants of the petroleum and gas industries stated that reserves within the country were not commercially viable. This scenario changed with the discovery of numerous oil and gas fields and resulted in the participation of numerous foreign companies bidding for exploration and production rights in the new fields established by ANP. Natural Gas has come to assume a new dimension with further recent discoveries in Santos, Espirito Santo, Sergipe and Urucu, with proven reserves in the order of 490 billion m3. This new dimension is reinforced by PETROBRAS's current strategic plan which considers investments in the order of 3.5 Billion U$ dollars for the production, processing and transport of Natural Gas and half a billion dollars for thermoelectric power stations. The use of Natural Gas in industries, in general, and in the generation of electricity will provide a strong push for the country's economy, substituting other sources of energy with the recognized advantages for production and reduced environmental impact. In this new era 24 gas distribution companies, widely distributed throughout Brazil, are also programming new investments to make best the use of Natural Gas for industry, commerce, for the residential sector and throughout all the national territory.

Natural gas supply and demand projections for the Asia-Pacific region

International Nuclear Information System (INIS)

Khin, J.A.

1992-01-01

The phenomenon of rapid economic growth in the Asia Pacific has inevitably led the countries of this region to expand and diversify their energy sources in order to satisfy their burgeoning energy demands. Natural gas has become an increasingly marketable energy source in this region benefitting from vast reserves and its advantages as an environmentally clean fuel. As a result of the impact of the two oil shocks of the 1970's on the Asia Pacific economy, the governments in the region set about the development of energy strategies which would make their national economies more resilient to the instabilities of world energy price and supply. The Japanese Gas Industry has estimated that the overall rise in demand for energy in Asia, set at an average rate of 3.7% per annum, will see a corresponding growth in demand for natural gas at 5%. Experts from a number of major oil companies, such as Exxon, expect an annual growth in the Asian natural gas market of 6.0 to 6.3%. These figures are over shadowed by the worldwide demand for natural gas which is expected to gain an 8% increase within the next two decades. Approximately 8.75% of the world's proven natural gas reserves are held in Asia-Pacific region (Table I). Most of the region's natural gas production will provide over 100 years of supply. A review of natural gas supply/demand in the Asia-Pacific region is presented in sub-regions, namely ASIAN, Northeast Asia, the Indian Subcontinent and Oceania

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

This study assesses the potential impacts on emissions and air quality from the increased adoption of natural gas-fired distributed generation of electricity (DG), including displacement of power from central power generation, in the contiguous United States. The study includes four major tasks: (1) modeling of distributed generation market penetration; (2) modeling of central power generation systems; (3) modeling of spatially and temporally resolved emissions; and (4) photochemical grid modeling to evaluate the potential air quality impacts of increased DG penetration, which includes both power-only DG and combined heat and power (CHP) units, for 2030. Low and high DG penetration scenarios estimate the largest penetration of future DG units in three regions - New England, New York, and California. Projections of DG penetration in the contiguous United States estimate 6.3 GW and 24 GW of market adoption in 2030 for the low DG penetration and high DG penetration scenarios, respectively. High DG penetration (all of which is natural gas-fired) serves to offset 8 GW of new natural gas combined cycle (NGCC) units, and 19 GW of solar photovoltaic (PV) installations by 2030. In all scenarios, air quality in the central United States and the northwest remains unaffected as there is little to no DG penetration in those states. California and several states in the northeast are the most impacted by emissions from DG units. Peak increases in maximum daily 8-h average ozone concentrations exceed 5 ppb, which may impede attainment of ambient air quality standards. Overall, air quality impacts from DG vary greatly based on meteorological conditions, proximity to emissions sources, the number and type of DG installations, and the emissions factors used for DG units.

Securing growth markets for natural gas

The Industry Development Strategy 2000-2005 (IDS) identifies the major growth markets for natural gas, as the industry readies itself for the challenges of the new millenium. An integral part of this process is to examine the key barriers to market expansion, and to devise strategies that both The Australian Gas Association (AGA) and the wider industry can pursue to underpin improvement in overall gas consumption. This is the task of the IDS which examines the opportunities confronting the industry over the next five year period. The significant growth prospects of the gas industry both in the short term (2000-2005) and long term (2005-2015) are indicated in two comprehensive and independent studies. The first, Australian Energy Market Developments and Projections to 2014-15, was released earlier this year by the Australian Bureau of Agricultural and Resource Economics (the ABARE Energy Report). The second, Natural Gas Consumption in Australia to 2015-Prospects by State, Industry and Sector, was commissioned by the AGA, and was completed by the National Institute of Economic and Industry Research in September 1999 (NIEIR Report). Both reports indicate that in terms of consumption levels, in the period up to 2015 the gas industry is forecast to more than double its current size. Natural gas is also projected to increase its primary energy share ranking from third to second place

This paper presents the methodology developed for the evaluation of the existing and potential market for natural gas in the industrial, automotive, residential and commercial sectors of Rio Grande do Sul. The methodology is based upon a marketing research framework and consists of the definition of the problem; application of qualitative, quantitative and stated-preference enquiries; review of the state-of-the-art and state-of-the-practice; and, also, interviews with specialists. The methodology is consolidated in four software that enable the simulation of different demand scenarios of natural gas up to the year 2010. The development of this methodology comprised the participation of more than 1,000 potential users of natural gas and allowed the state company in charge of distributing natural gas to: structure the problem of forecasting the consumption of natural gas within a new context of competition in the energy industry; help the formulation of the strategic plan of the company with regard to investment strategies and incrementing the number of clients; and propose marketing efforts to promote the adoption of natural gas as an alternative energy source.

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

WestPac Terminals Inc. has expertise in natural gas supply and demand, transportation, liquefied natural gas (LNG) and economic optimization. This presentation addressed issues facing their proposed construction of an LNG terminal and associated facilities on the west coast of Canada. It presented pie charts comparing world gas reserves with production. NPC gas price projects and WestPac gas cost estimates were also presented. It was noted that an unprecedented growth in LNG imports to North America is essential and that LNG will be the lowest price major source of natural gas supply. Maps illustrating LNG sources and receiving terminals were also presented along with solutions to the not-in-my-back-yard (NIMBY) syndrome. Solutions include selecting locations where communities are pro-development, where LNG terminals can provide direct financial benefits to the community, and using existing infrastructure to minimize socio-economic impacts. The advantages of developing LNG to Prince Rupert were discussed in terms of serving energy markets, direct provincial benefits, and LNG/power generation synergies. figs

Hansi Liu

2017-10-01

Full Text Available In this paper, we used the life-cycle analysis (LCA method to evaluate the energy consumption and greenhouse gas (GHG emissions of natural gas (NG distributed generation (DG projects in China. We took the China Resources Snow Breweries (CRSB NG DG project in Sichuan province of China as a base scenario and compared its life cycle energy consumption and GHG emissions performance against five further scenarios. We found the CRSB DG project (all energy input is NG can reduce GHG emissions by 22%, but increase energy consumption by 12% relative to the scenario, using coal combined with grid electricity as an energy input. The LCA also indicated that the CRSB project can save 24% of energy and reduce GHG emissions by 48% relative to the all-coal scenario. The studied NG-based DG project presents major GHG emissions reduction advantages over the traditional centralized energy system. Moreover, this reduction of energy consumption and GHG emissions can be expanded if the extra electricity from the DG project can be supplied to the public grid. The action of combining renewable energy into the NG DG system can also strengthen the dual merit of energy conservation and GHG emissions reduction. The marginal CO2 abatement cost of the studied project is about 51 USD/ton CO2 equivalent, which is relatively low. Policymakers are recommended to support NG DG technology development and application in China and globally to boost NG utilization and control GHG emissions.

Natural gas fuel is a green fuel and becoming very demanding because it is environmental safe and clean. Furthermore, this fuel emits lower levels of potentially harmful by-products into the atmosphere. Most of the explored crude natural gas is of sour gas and yet, very viable and cost effective technology is still need to be developed. Above all, methanation technology is considered a future potential treatment method for converting the sour natural gas to sweet natural gas.

Natural gas liquids: market outlook

Heath, M.

1996-01-01

Future market outlook for natural gas liquids was discussed. It was shown that Canadian natural gas and natural gas liquid (NGL) production levels have experienced extraordinary growth over the past few years due to an increased U.S. demand for Canadian natural gas. Recent supply and demand studies have indicated that there will be growing surpluses of NGLs in Canada. By 1996, the majority of NGL surplus that is forecast to be available is ethane (64%), followed by propane (22%), butane (12%) and pentane plus (2%). Throughout the forecast period, the ratio of incremental ethane to the total NGL surplus, over and above forecast demand, was expected to continue to rise. The viability of producing and processing that ethane and transporting it to market, will be crucial. Development of a large ex-Alberta C2+ pipeline from Empress to Mont Belvieu under the reference case supply projection is a possibility, but only if total tariff and fractionation charge on the line is less than or equal to 10 US cents/USG (currently 16-22 US cents/USG). 11 figs

Development of a natural Gas Systems Analysis Model (GSAM)

Godec, M.; Haas, M.; Pepper, W.; Rose, J.

1993-01-01

Recent dramatic changes in natural gas markets have significant implications for the scope and direction of DOE's upstream as well as downstream natural gas R ampersand D. Open access transportation changes the way gas is bought and sold. The end of the gas deliverability surplus requires increased reserve development above recent levels. Increased gas demand for power generation and other new uses changes the overall demand picture in terms of volumes, locations and seasonality. DOE's Natural Gas Strategic Plan requires that its R ampersand D activities be evaluated for their ability to provide adequate supplies of reasonably priced gas. Potential R ampersand D projects are to be evaluated using a full fuel cycle, benefit-cost approach to estimate likely market impact as well as technical success. To assure R ampersand D projects are evaluated on a comparable basis, METC has undertaken the development of a comprehensive natural gas technology evaluation framework. Existing energy systems models lack the level of detail required to estimate the impact of specific upstream natural gas technologies across the known range of geological settings and likely market conditions. Gas Systems Analysis Model (GSAM) research during FY 1993 developed and implemented this comprehensive, consistent natural gas system evaluation framework. Rather than a isolated research activity, however, GSAM represents the integration of many prior and ongoing natural gas research efforts. When complete, it will incorporate the most current resource base description, reservoir modeling, technology characterization and other geologic and engineering aspects developed through recent METC and industry gas R ampersand D programs

Mallardi, P.

1991-01-01

A sectoral analysis of current trends in the use of natural gas in Italy shows that this energy source, now estimated to be covering 23.7% of total Italian national energy requirements, is fulfilling its role as an environmentally compatible, low cost and readily available energy alternative well suited to alleviate Italy's worrisome over-dependence on foreign supplied oil and reduce the severity of the urban air pollution problem (it being a low nitrogen oxide and carbon dioxide emitting, non-sulfur containing fuel). This paper expands this theme by giving a complete panorama of the natural gas market in Italy, sector by sector, and by coupling projections on the expected increased use of this energy source (as mandated by the National Energy Plan) with estimates of consequent reductions in air pollution based on a comparative analysis of fuel oil versus natural gas combustion

Thirty four years ago the natural gas field Slochteren in Groningen, Netherlands made the Netherlands into an outstanding natural gas country. Last summer, exactly half of the original 2680 trillion m 3 of natural gas has been extracted. According to the projections of the Dutch Gasunie the Dutch gas reserves will be about depleted after another thirty four years. To guarantee continuity of the natural gas supply the natural gas will have to become more expensive. Also considerable investments in storage capacity are needed. Comments and opinions of experts regarding the future of the Dutch natural gas market are presented. 2 figs., 14 ills

The Gas Hydrates Project at the U.S. Geological Survey (USGS) focuses on the study of methane hydrates in natural environments. The project is a collaboration between the USGS Energy Resources and the USGS Coastal and Marine Geology Programs and works closely with other U.S. Federal agencies, some State governments, outside research organizations, and international partners. The USGS studies the formation and distribution of gas hydrates in nature, the potential of hydrates as an energy resource, and the interaction between methane hydrates and the environment. The USGS Gas Hydrates Project carries out field programs and participates in drilling expeditions to study marine and terrestrial gas hydrates. USGS scientists also acquire new geophysical data and sample sediments, the water column, and the atmosphere in areas where gas hydrates occur. In addition, project personnel analyze datasets provided by partners and manage unique laboratories that supply state-of-the-art analytical capabilities to advance national and international priorities related to gas hydrates.

This study describes the Mexican natural gas industry as it exists today and the factors that have shaped the evolution of the industry in the past or that are expected to influence its progress; it also projects production and use of natural gas and estimates the market for exports of natural gas from the United States to Mexico. The study looks ahead to two periods, a near term (1993--1995) and an intermediate term (1996--2000). The bases for estimates under two scenarios are described. Under the conservative scenario, exports of natural gas from the United States would decrease from the 1992 level of 250 million cubic feet per day (MMCF/d), would return to that level by 1995, and would reach about 980 MMCF/D by 2000. Under the more optimistic scenario, exports would decrease in 1993 and would recover and rise to about 360 MMCF/D in 1995 and to 1,920 MMCF/D in 2000

Under the auspices of the National Energy Technology Laboratory and the US Department of Energy, the Clean Vehicle Education Foundation conducted a three-year program to increase the understanding of the safe and proper use and maintenance of vehicular compressed natural gas (CNG) fuel systems. High-pressure fuel systems require periodic inspection and maintenance to insure safe and proper operation. The project addressed the needs of CNG fuel containers (cylinders) and associated high-pressure fuel system components related to existing law, codes and standards (C&S), available training and inspection programs, and assured coordination among vehicle users, public safety officials, fueling station operators and training providers. The program included a public and industry awareness campaign, establishment and administration of a cylinder inspector certification training scholarship program, evaluation of current safety training and testing practices, monitoring and investigation of CNG vehicle incidents, evaluation of a cylinder recertification program and the migration of CNG vehicle safety knowledge to the nascent hydrogen vehicle community.

This paper is the press release of the talk given at the `Gaz de France scientific meeting with the press` by P. Gadonneix, chairman of Gaz de France company, on October 7, 1998. The aim of this talk concerns the new French and European supply link for bringing natural gas from the Norwegian North Sea fields. This new supply link is the first direct link between Norway and France and the NorFra gas pipeline which brings natural gas from the North Sea to France is the longest offshore pipeline in the world. The `Artere des Hauts de France` pipeline (the largest diameter gas pipeline ever laid in France) is devoted to the transfer of natural gas from Dunkerque to the Gournay-sur-Aronde underground storage site. This paper describes successively: the French European gas supply hub, the NorFra project, the Artere des Hauts de France pipeline, the network performance research, the safety and quality guaranties, the reduction of overland natural gas transmission costs (improvement of pipe-laying techniques and optimization of line route and welding operations), the specific techniques used for road and river crossing (micro-tunnel digging, river-crossing ditches) and for anchoring (buoyancy compensation). Finally, the environmental impact of the laying operations is briefly described. (J.S.)

Trading in LNG and natural gas

International Nuclear Information System (INIS)

1992-01-01

We have examined the market for natural gas from a number of viewpoints, starting with the role of natural gas in the global energy market where its 20% share of primary energy demand has been captured in the space of almost as many years. In discussion regional energy markets we cover the disparities between supply and demand which give rise to trade by pipeline, and by sea in the form of liquefied natural gas (LNG). Both have in fact increased steadily in recent years, yet even in 1991, only 12-15% of total gas production was traded across international boundaries, whereas for oil it was closer to 40%. For the moment pipeline trade remains heavily concentrated in Europe and North America, and it is in the LNG sector where the spread of projects, both existing and planned, is more global in nature. We examine the development of LNG trades and the implications for shipping. Finally, we look at transportation costs, which are likely to be an important component in the viability of many of the natural gas export schemes now under review. There is good reason to be ''bullish'' about parts of the natural gas industry but this Report suggests that there are areas of concern which could impinge on the development of the market in the 1990s.

The Secondary Natural Gas Recovery (SGR): Targeted Technology Applications for Infield Reserve Growth is a joint venture research project sponsored by the Gas Research Institute (GRI), the US Department of Energy (DOE), the State of Texas through the Bureau of Economic Geology at The University of Texas at Austin, with the cofunding and cooperation of the natural gas industry. The SGR project is a field-based program using an integrated multidisciplinary approach that integrates geology, geophysics, engineering, and petrophysics. A major objective of this research project is to develop, test, and verify those technologies and methodologies that have near- to mid-term potential for maximizing recovery of gas from conventional reservoirs in known fields. Natural gas reservoirs in the Gulf Coast Basin are targeted as data-rich, field-based models for evaluating infield development. The SGR research program focuses on sandstone-dominated reservoirs in fluvial-deltaic plays within the onshore Gulf Coast Basin of Texas. The primary project research objectives are: To establish how depositional and diagenetic heterogeneities cause, even in reservoirs of conventional permeability, reservoir compartmentalization and hence incomplete recovery of natural gas. To document examples of reserve growth occurrence and potential from fluvial and deltaic sandstones of the Texas Gulf Coast Basin as a natural laboratory for developing concepts and testing applications. To demonstrate how the integration of geology, reservoir engineering, geophysics, and well log analysis/petrophysics leads to strategic recompletion and well placement opportunities for reserve growth in mature fields.

It is no surprise that regional natural gas supply and demand patterns in North America are constantly changing. A consensus of forecasters agree that the natural gas resource base is larger than envisaged in the early 1980s due to advances in exploration and production technology. In addition, on the demand side more gas will be burned by US power generators to meet growth in electricity. Gas consumption is up in the commercial sector, and natural gas is correctly seen as environmentally protective. But how much more natural gas does the US need? This paper reports that new pipeline projects are springing up all over the nation --- 43 to be exact, with most of them connecting gas deliverability out of basins west of the Mississippi to new markets along the Atlantic and Pacific coasts

As a strategic project management with a transport capacity of 31 billion m{sup 3} per year of natural gas, Nabucco 1.0 should diversify the natural gas suppliers for the EU market and the import pipeline network. Significant amounts of natural gas should be imported from the Caspian and the Middle East region. Nabucco 1.0 failed as a project management. The Nabucco consortium wants to convey natural gas through a small-scale and cheaper Nabucco west pipeline via Bulgaria, Romania and Hungary to Austria. Also the Trans-Adriatic Pipeline will transport the same natural gas reserves into the European Union (EU).

IGNITION IMPROVEMENT OF LEAN NATURAL GAS MIXTURES

Energy Technology Data Exchange (ETDEWEB)

Jason M. Keith

2005-02-01

This report describes work performed during a thirty month project which involves the production of dimethyl ether (DME) on-site for use as an ignition-improving additive in a compression-ignition natural gas engine. A single cylinder spark ignition engine was converted to compression ignition operation. The engine was then fully instrumented with a cylinder pressure transducer, crank shaft position sensor, airflow meter, natural gas mass flow sensor, and an exhaust temperature sensor. Finally, the engine was interfaced with a control system for pilot injection of DME. The engine testing is currently in progress. In addition, a one-pass process to form DME from natural gas was simulated with chemical processing software. Natural gas is reformed to synthesis gas (a mixture of hydrogen and carbon monoxide), converted into methanol, and finally to DME in three steps. Of additional benefit to the internal combustion engine, the offgas from the pilot process can be mixed with the main natural gas charge and is expected to improve engine performance. Furthermore, a one-pass pilot facility was constructed to produce 3.7 liters/hour (0.98 gallons/hour) DME from methanol in order to characterize the effluent DME solution and determine suitability for engine use. Successful production of DME led to an economic estimate of completing a full natural gas-to-DME pilot process. Additional experimental work in constructing a synthesis gas to methanol reactor is in progress. The overall recommendation from this work is that natural gas to DME is not a suitable pathway to improved natural gas engine performance. The major reasons are difficulties in handling DME for pilot injection and the large capital costs associated with DME production from natural gas.

An examination of the International Natural Gas Trade

International Nuclear Information System (INIS)

Mazighi, A.

2003-01-01

Recent developments in the liquefied natural gas (LNG) industry, particularly the ongoing projects of liquefaction and regasification and the increasing number of LNG-carriers to be delivered in forthcoming years, have led some specialists to argue that LNG is today a crossroads between regionalisation and globalisation. Other specialists think that, by LNG's share of the total international trade of natural gas will be predominant, compared to that of pipelines. All these assumptions are based on an examination of the duration and ongoing international gas projects. The objective of our article is to examine the historical patterns of the international natural gas and discuss the conditions for the globalisation of LNG trade. Using some evidence on the international trade of natural gas from 1970 to 1997, we show the A strong correlation exists between the international trade of gas by pipeline and LNG becomes predominant, we need a delinking of these two means of trading gas. Globalisation of the LNG trade is not only linked to an increase in the relative share trade; it is also and primarily linked to an increase in the inter-area trade of LNG. There is a negligible change in the pattern of inter-area and intra-area trade of even during the late 1990s; this is due to the contracted nature of the LNG international that resulted in a stickiness of LNG routes. The emergence of a global LNG market requires the satisfaction of four conditions: economic, technical and institutional conditions - therefore, it will certainly take more years to make ING a global commodity.

In the United States, recent shale gas discoveries have generated renewed interest in using natural gas as a vehicular fuel, primarily in fleet applications, while outside the United States, natural gas vehicle use has expanded significantly in the past decade. In this report for the U.S. Department of Energy's Clean Cities Program - a public-private partnership that advances the energy, economic, and environmental security of the U.S. by supporting local decisions that reduce petroleum use in the transportation sector - we have examined the state of natural gas vehicle technology, current market status, energy and environmental benefits, implications regarding advancements in European natural gas vehicle technologies, research and development efforts, and current market barriers and opportunities for greater market penetration. The authors contend that commercial intracity trucks are a prime area for advancement of this fuel. Therefore, we examined an aggressive future market penetration of natural gas heavy-duty vehicles that could be seen as a long-term goal. Under this scenario using Energy Information Administration projections and GREET life-cycle modeling of U.S. on-road heavy-duty use, natural gas vehicles would reduce petroleum consumption by approximately 1.2 million barrels of oil per day, while another 400,000 barrels of oil per day reduction could be achieved with significant use of natural gas off-road vehicles. This scenario would reduce daily oil consumption in the United States by about 8%.

Accounting for fuel price risk: Using forward natural gas prices instead of gas price forecasts to compare renewable to natural gas-fired generation

Energy Technology Data Exchange (ETDEWEB)

Bolinger, Mark; Wiser, Ryan; Golove, William

2003-08-13

Against the backdrop of increasingly volatile natural gas prices, renewable energy resources, which by their nature are immune to natural gas fuel price risk, provide a real economic benefit. Unlike many contracts for natural gas-fired generation, renewable generation is typically sold under fixed-price contracts. Assuming that electricity consumers value long-term price stability, a utility or other retail electricity supplier that is looking to expand its resource portfolio (or a policymaker interested in evaluating different resource options) should therefore compare the cost of fixed-price renewable generation to the hedged or guaranteed cost of new natural gas-fired generation, rather than to projected costs based on uncertain gas price forecasts. To do otherwise would be to compare apples to oranges: by their nature, renewable resources carry no natural gas fuel price risk, and if the market values that attribute, then the most appropriate comparison is to the hedged cost of natural gas-fired generation. Nonetheless, utilities and others often compare the costs of renewable to gas-fired generation using as their fuel price input long-term gas price forecasts that are inherently uncertain, rather than long-term natural gas forward prices that can actually be locked in. This practice raises the critical question of how these two price streams compare. If they are similar, then one might conclude that forecast-based modeling and planning exercises are in fact approximating an apples-to-apples comparison, and no further consideration is necessary. If, however, natural gas forward prices systematically differ from price forecasts, then the use of such forecasts in planning and modeling exercises will yield results that are biased in favor of either renewable (if forwards < forecasts) or natural gas-fired generation (if forwards > forecasts). In this report we compare the cost of hedging natural gas price risk through traditional gas-based hedging instruments (e

Possibilities of the natural gas supply in the Republic of Croatia

International Nuclear Information System (INIS)

Mavrovic, S.; Matic, D.

1996-01-01

Europe and Croatia meet 70% of their total natural gas demand from indigenous production and import other 30% (20% from the Russian Federation and 10% from Algeria). Croatia imports gas only from Russia. Forecasts and analysis of energy sector development point out that natural gas consumption will be doubled till 2010 when it will reach approximately 555-651 bcm. Natural gas consumption is expected to rise significantly in Croatia. Estimations of required import made by INA and PROHES - preliminary results, are similar. It has been expected that future import in 2010 will be between 2 and 3 bcm depending on considered scenario. Due to expectations of rising gas demand, Europe is turning on to new projects aiming to better connections by pipelines and LNG chains. New projects are considering constructions of new Russian transmission lines, additional lines from North Sea, increasing capacity of lines from Algeria, UK interconnection with Continent, and new pipelines and LNG routes from Middle East and Central Asia. Involvement in some the above mentioned projects is of importance for Croatia because it enables additional natural gas quantities and diversification of sources. (author)

Since September 2010, ArcelorMittal Monlevade has gained flexibility and an important opportunity to reduce the cost of its energy mix due to the arrival of the Natural Gas (NG) via Steel Valley Pipeline. The proposal of the project included the substitution of the Liquefied Petroleum Gas (LPG), Fuel Oil and Compressed Natural Gas for natural gas via pipeline. To support the investment decision, in addition to domestic economic and technical aspects, the macro economic environment concerning the NG was also taken into account. This paper shows the analysis for adjustment of internal equipment, the structure of the contract, the conceptual project of the gas distribution built inside the main events, the gains achieved, the alternatives for the acquisition of NG and operational flexibility of ArcelorMittal Monlevade in case of interruption of supply of natural gas.

Furthermore, Turkey is planning to increase its oil and gas pipeline infrastructure to accommodate its increased energy consumption. Naturally, Turkish natural gas usage is projected to increase remarkably in coming years, with the prime consumers, expected to be industry and power plants. Energy demand of Turkey is growing by 8% annually, one of the highest rates in the world. In addition, natural gas consumption is the fastest growing primary energy source in Turkey. Gas sales started at 0.5 bcm (billion cubic meters), in 1987 and reached approximately 22 bcm in 2003. This article deals with energy policies and natural gas consumption of Turkey. Besides modernization of present lines and realization of capacity increase, new lines will also be needed. In this context, Turkey, due to its geographical location is, in an important position to vary European supply. Therefore, Turkey's role as a transitory area gains importance

Radon and thoron concentrations in soil pores in a gas production region of the Anzoategui State, Venezuela, were determined by active and passive methods. In this region, water wells are contaminated by natural gas and gas leaks exist in the nearby river. Based on soil gas Radon data surface hydrocarbon seeps were identified. Radon and thoron concentration maps show anomalously high values near the river gas leaks decreasing in the direction of water wells where natural gas is also detected. The area where the highest concentrations of 222 Rn were detected seems to indicate the surface projection of the aquifer contaminated with natural gas. The Radon/Thoron ratio revealed a micro-localized anomaly, indicating the area where the gas comes from deep layers of the subsoil. The radon map determined by the passive method showed a marked positive anomaly around abandoned gas wells. The high anomalous Radon concentration localized near the trails of ascending gas bubbles at the river indicates the zone trough where natural gases are ascending with greater ease, associated with a deep geological fault, being this the main source of methane penetration into the aquifer. It is suggested that the source of the natural gas may be due to leaks at deep sites along the structure of some of the abandoned wells located at the North-East of the studied area. - Highlights: ► High Radon/Thoron ratios were localized near the natural-gas emanations in a river. ► Natural gases are ascending trough a deep geological fault. ► Apparently, the radon anomaly shows the site where natural gas enters the aquifer. ► Natural gas source may be related to leaks in the structure of abandoned gas wells

Natural Gas Reserves, Development and Production in Qatar

Qatar entered the club of natural gas exporters in early 1997 when the first shipment of liquefied natural gas left the state for Japan. Qatar was helped by the discovery in 1971 of supergiant North Field gas field, the country's suitable location between the established gas consuming markets in Europe and Southeast Asia, and its proximity to developing markets in the Indian subcontinent and in neighbouring countries. All that have combined to make gas export projects from Qatar economically viable and commercially attractive. In addition to export-oriented development, increased gas production from the North Field is planned for meeting a growing domestic demand for gas as fuel and feedstock for power generation and desalination plants, as well as value-added petrochemical and fertilizer industries

Environmental benefits of natural gas for buses

Rabl, A.

2002-01-01

This paper presents a life cycle assessment comparing diesel buses with buses fueled by natural gas. The data for the emission of pollutants are based on the MEET Project of the European Commission (EC), supplemented by data measured for diesel and gas buses in Paris. The benefits of the gas fueled bus are then quantified using the damage cost estimates of the ExternE Project of the EC. A diesel bus with emissions equal to Standard EURO2 of the EC is compared with the same bus equipped with a natural gas engine, for use in Paris and in Toulouse. The damage cost of a diesel bus is significant, in the range of 0.4-1.3 euro/km. Natural gas allows an appreciable reduction of the emissions, lowering the damage cost by a factor of about 2.5 (Toulouse) to 5.5 (Paris). An approximate rule is provided for transferring the results to other cities. A sensitivity analysis is carried out to evaluate the effect of the evolution of the emissions standard towards EURO3, 4 and 5, as well as the effect of uncertainties. Finally a comparison is presented between a EURO2 diesel bus with particle filter, and a gas fueled bus with the MPI engine of IVECO, a more advanced and cleaner technology. With this engine the damage costs of the gas fueled bus are about 3-5 times lower than those of the diesel with particle filter, even though the latter has already very low emissions.(author)

The Brazilian energy matrix has been showing a huge increase in the demand of natural gas due mainly to industries and power plants. Today the Brazilian gas market is supplied with gas produced by PETROBRAS and imported from Bolivia. To increase the Brazilian gas supply, on the short and middle term, PETROBRAS will import LNG (liquefied natural gas) and exploit the new offshore fields discovered on the pre-salt area. The only proven technology available today to bring this offshore gas to the market is the pipeline, but its costs for the pre-salt area are high enough to keep the solution economically attractive. So, PETROBRAS are evaluating and developing alternative ways to transport offshore gas, such as LNG, CNG (Compressed Natural Gas), GTS (Gas-to-Solids or Natural Gas Hydrates) and ANG (Adsorbed Natural Gas). Using information available in the literature, this paper analyses the main concepts of CNG and LNG floating unities. This paper also presents the PETROBRAS R and D results on ANG and GTS aiming at offshore application. (author)

Eastern Canada natural gas developments

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

Substantial increases in demand for Canadian petroleum and natural gas in both domestic and export markets resulted in another good year throughout the main sectors of the industry. In February, production averaged 850,000 bpd, or about 8% more than 1963 output of crude oil and natural gas liquids. Construction began on the first full scale plant for the extraction of oil from the Athabasca bituminous sands. In 1964, exploratory and development drilling in western Canada increased 10% from the previous year. A total of 15.5 million ft was drilled, the largest since the record drilling year of 1956. The main oil field development areas in Alberta were the House Mountain, Deer Mountain and Goose River Fields, and the Bantry-Taber heavy oil region in southeastern Alberta. Oil reserves were increased substantially by waterflood pressure maintenance projects in many of the older oil fields. The largest oil accumulation discovered in 1964 was the Syvia-Honda Field in the Devonian Gilwood sandstone in N.-central Alberta. Two graphs illustrate the crude petroleum in Canada in millions of barrels from 1940 to 1964, and natural gas in Canada in billions of cu ft from 1950 to 1964. The outlook for the industry in 1965 is good.

Freedenthal, C.

1993-01-01

In recent years, natural gas has gained new momentum because of changes in marketing and regulations. The gas industry has always received an inordinate amount of regulatory control starting at the well head where the gas is produced to the consuming burner tip. Regulations have drastically impacted the availability of gas. Changes in the marketing and regulations have made the natural gas market sensitive at the point of production, the well head. Now, with plentiful supply and ease of transportation to bring the gas from the producing fields to the consumer, natural gas markets are taking advantage of the changed conditions. At the same time, new markets are developing to take advantage of the changes. This section shows consumers, especially the energy planners for large buyers of fuel, the advantages, sources and new methods of securing natural gas supplies. Background on how natural gas is produced and marketed are given. This section lists marketing sources, regulatory agencies and information groups available to help buyers and consumers of this important fuel for US industries and residences. 7 figs., 8 tabs

Hyde, Dan; Collier, Kirk

2009-01-22

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

This paper reports that western Canada's biggest sour natural gas, sulfur, and natural gas liquids development project in 2 decades is on target to start up late this year. Shell Canada Ltd.'s $950 million (Canadian) Caroline project will produce 2 tcf of gas and associated products from the Swan Hills member of the middle Devonian Beaverhill Lake group. The price tag will reach about $1 billion, including some start-up costs. The project is designed to process an average 300 MMcfd of gas. It will produce 17,500 b/d of pentanes plus, 4,100 metric tons/day of sulfur, 90 MMcfd of sales gas, and 28,000 b/d of NGL-ethane, propane, and butane. A labor force that is peaking at about 2,400 workers is completing a network of processing plants, about 143 miles of pipeline, three field compressors, and other facilities covering an area of 161 sq miles. Dilcon Constructors Ltd., an arm of Delta Catalytic Corp., Calgary, is the main contractor for the project. About 85% of the services and equipment for Caroline are coming from Alberta suppliers, 7% from suppliers elsewhere in Canada, and only 8% from non-Canadian Sources

Fuel strategies for natural gas fired cogeneration and IPP projects

International Nuclear Information System (INIS)

Gottlieb, J.W.

1992-01-01

This paper as published is the outline of a presentation on managing the risk of varying fuel costs as part of a successful fuel strategy for natural gas fired cogeneration and Independent Power Producer (IPP) projects. So long as the fuel cost that electric utilities recover from their ratepayers differs from the fuel costs incurred by IPP and Qualifying Facility (QF) plant operators, the largest variable cost risk of any QF or IPP will continue to be the cost of fuel. Managing that risk is the mission of any successful fuel procurement strategy. Unfortunately, a quick review of the last 20 years in the oil and gas industry reveals dramatic and substantial changes in price and fuel availability that few, if any, industry experts could have predicted in 1971. Recognizing that the fuel cost risk to a QF or IPP investor also spans a 20 year period, the typical term of a QF or IPP power purchase contract, a successful fuel procurement strategy must consider and address the likelihood of future changes. Due to federal and state regulatory changes made from 1978 to 1989, the current structure of the oil and gas industry appears to provide end-users with the tools to improve the manageability of fuel cost risks. QF and IPP developers can choose the type of service they desire and can negotiate most of the contractual elements of that service. Until electric utilities are allowed to flow through their rates the fuel costs incurred by QFs and IPPs, a thorough analysis of the available fuel procurement options prior to development of a QF or IPP will continue to be absolutely necessary

The current expansion of natural gas (NG) development in the United States requires an understanding of how this change will affect the natural gas industry, downstream consumers, and economic growth in order to promote effective planning and policy development. The impact of this expansion may propagate through the NG system and US economy via changes in manufacturing, electric power generation, transportation, commerce, and increased exports of liquefied natural gas. We conceptualize this problem as supply shock propagation that pushes the NG system and the economy away from its current state of infrastructure development and level of natural gas use. To illustrate this, the project developed two core modeling approaches. The first is an Agent-Based Modeling (ABM) approach which addresses shock propagation throughout the existing natural gas distribution system. The second approach uses a System Dynamics-based model to illustrate the feedback mechanisms related to finding new supplies of natural gas - notably shale gas - and how those mechanisms affect exploration investments in the natural gas market with respect to proven reserves. The ABM illustrates several stylized scenarios of large liquefied natural gas (LNG) exports from the U.S. The ABM preliminary results demonstrate that such scenario is likely to have substantial effects on NG prices and on pipeline capacity utilization. Our preliminary results indicate that the price of natural gas in the U.S. may rise by about 50% when the LNG exports represent 15% of the system-wide demand. The main findings of the System Dynamics model indicate that proven reserves for coalbed methane, conventional gas and now shale gas can be adequately modeled based on a combination of geologic, economic and technology-based variables. A base case scenario matches historical proven reserves data for these three types of natural gas. An environmental scenario, based on implementing a $50/tonne CO 2 tax results in less proven

Liquefied natural gas (LNG) is making progress with several projects of terminal facilities and liquefaction plants everywhere in the world. This too fast development leads to an increase of costs and delays in the construction of LNG facilities and at the medium term the offer will become unable to meet the demand. Today, the LNG engineering market is living on the 2005-2006 endorsed projects but the turning point will be 2010 when all main projects will be achieved. (J.S.)

Gas projects surge in the Middle East as governments seek new revenue sources

International Nuclear Information System (INIS)

Williams, M.D.

1997-01-01

The rapid development of natural gas and condensate reserves in the Middle East results from a simple motivation: the desire of governments to earn revenues. For the past decade, Middle East governments have run budget deficits, which they funded by drawing down foreign assets and issuing debt. Now in the process of structural economic reform, they have begun to use an under-utilized resource--natural gas, of which Middle East governments own about one third of the world's reserves. Governments receive revenues from several sources in natural gas developments, which makes the projects very attractive. Revenue comes from the sale of the natural gas in the domestic market and, if exported, the international market; the sale of associated condensates; the additional exports of crude oil or refined products if natural gas is substituted for refined products in domestic markets; the increased sale of crude oil if natural gas is injected into reservoirs to maintain pressure; and the sale of petrochemicals where natural gas is used as feedstock. Large projects under way in the Middle East highlight the consequences of multiple revenue sources and interlinked costs of natural gas and condensate development. Other countries in the region are undertaking similar projects, so examples cited represent only a portion of what is occurring. The paper describes Abu Dhabi, Qatar, Saudi Arabia, and Iran

Natural gas and production of electricity

International Nuclear Information System (INIS)

Defago, E.

2005-01-01

The forthcoming power supply shortage in Switzerland due to increasing consumption is discussed, as are the possibilities for securing the future supply. Today, the main sources are hydroelectric (roughly 55 %) and nuclear (40 %) power. The share of electricity from natural gas amounts to only 1.4 %. The possibilities of further economic production of hydropower are practically exhausted. Therefore, further electric power has to be either imported or generated from other energy sources (renewable, nuclear, fossil) in the country itself. Due to the low acceptance of nuclear energy and the limited potential of renewable energy sources, natural gas is the most favoured candidate. The advantages of distributed production in cogeneration plants are compared with the centralized production in larger plants using combined cycles. Finally, a project currently under development is presented: an existing thermal power plant fueled with heavy fuel oil shall be refurbished and converted to natural gas as the new fuel

Maiden, C J

1986-01-01

This paper describes how the products of New Zealand's natural gas fields are to be used in the transport sector to reduce oil imports. As a result of such developments New Zealand will be about 53% self-sufficient in transport fuels in 1986/1987. This self-sufficiency will be made up as follows: 25% from condensate from gas fields, 18% from synthetic gasoline, 5% from the use of compressed natural gas (CNG) and liquefied petroleum gas (LPT) in vehicles and 5% from indigenous oil supplies. History and status of the CNG Programme are outlined. Government has set a goal of 200,000 vehicles operating on CNG by 1990 and, at present, about 80,000 vehicles are powered by natural gas. The Gas to Gasoline project is described in some detail. New Zealand's imports of crude oil and oil products for 1986/1987 are forecast to total 1,900,000 tonnes, less than one-half of the 4,257,000 tonnes of comparable imports in 1973/1974.

In development of energy diversification strategy, so much in the use of available sources as in the supply of alternative to the final consumer, one comes advancing in Colombia, for several years, the national plan of gas overcrowding. The growing use of natural gas for the new projects of thermal generation has put in evidence the strong link and the existent dependence among of the gas and electric sub sectors. Such a nexus is manifested in four aspects: The electric power substitution for gas affects the demand of both products. The development of the production infrastructure and transport of the natural gas depends in a large part of the electric generation with gas. The costs of electric generation depend directly on the costs of the gas, included that of their transport. The regulation of the natural gas affects the costs of the electric power and vice versa. In this article the nexus and the coordination of both sectors are analyzed and they think about some actions to improve this last one

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

NATURAL GAS HYDRATES STORAGE PROJECT PHASE II. CONCEPTUAL DESIGN AND ECONOMIC STUDY

Energy Technology Data Exchange (ETDEWEB)

R.E. Rogers

1999-09-27

DOE Contract DE-AC26-97FT33203 studied feasibility of utilizing the natural-gas storage property of gas hydrates, so abundantly demonstrated in nature, as an economical industrial process to allow expanded use of the clean-burning fuel in power plants. The laboratory work achieved breakthroughs: (1) Gas hydrates were found to form orders of magnitude faster in an unstirred system with surfactant-water micellar solutions. (2) Hydrate particles were found to self-pack by adsorption on cold metal surfaces from the micellar solutions. (3) Interstitial micellar-water of the packed particles were found to continue forming hydrates. (4) Aluminum surfaces were found to most actively collect the hydrate particles. These laboratory developments were the bases of a conceptual design for a large-scale process where simplification enhances economy. In the design, hydrates form, store, and decompose in the same tank in which gas is pressurized to 550 psi above unstirred micellar solution, chilled by a brine circulating through a bank of aluminum tubing in the tank employing gas-fired refrigeration. Hydrates form on aluminum plates suspended in the chilled micellar solution. A low-grade heat source, such as 110 F water of a power plant, circulates through the tubing bank to release stored gas. The design allows a formation/storage/decomposition cycle in a 24-hour period of 2,254,000 scf of natural gas; the capability of multiple cycles is an advantage of the process. The development costs and the user costs of storing natural gas in a scaled hydrate process were estimated to be competitive with conventional storage means if multiple cycles of hydrate storage were used. If more than 54 cycles/year were used, hydrate development costs per Mscf would be better than development costs of depleted reservoir storage; above 125 cycles/year, hydrate user costs would be lower than user costs of depleted reservoir storage.

Emission improvement in both city centers and conurbations is an important factor which developers of public-utility vehicles and buses must take into account. If natural gas is used as a fuel the emission is considerably lower than that from conventional diesel drive. Thus it is an important contribution to keep the air clean in the area where the vehicles are deployed. In this paper the project 'Ecological Natural gas drive for city buses in Skopje' is analysed.

This paper presents a project to integrate expert system and dynamic simulation of natural gas transportation network applying the concept of agents. Natural gas pipeline operation requires the intermittent analysis of hundreds interrelated operational parameters, which represent the network state. The combination of expert system and dynamic simulation is a synergic solution for this kind of problem. With expert system techniques, it is possible to implement rules that describe the relationship between current operational parameters and the network normal operational conditions based on heuristic knowledge. By applying such rules, the system aims to evaluate the real network state and to predict abnormal conditions via dynamic simulation, allowing time analysis of operational situation in advance. At the current stage, the project presents a well defined model. The process of knowledge acquisition and representation has taken place following an incremental approach, considered as development paradigm. The project objectives are to reduce costs, increase the reliability and organize pipeline operation and maintenance information. This work is part of SEGRED project established as partnership among LASHIP/UFSC, SCGAS, TBG and PETROBRAS. The project also received support from FINEP. (author)

Opportunities to reduce methane emissions in the natural gas industry

Cowgill, R.M. [Radian Corporation, Austin, TX (United States)

1995-12-31

The U.S. Environmental Protection Agency (EPA) and the Gas Research Institute (GRI) cofunded a project to quantify methane (CH{sub 4}) emissions from the U.S. natural gas industry. Methane, the major constituent of natural gas, is a potent greenhouse gas that is believed to increase the effect of global warming when released to the atmosphere. Reducing emissions from natural gas systems would lessen the greenhouse gas effect attributable to atmospheric CH{sub 4}. Further, mitigation methods to reduce emissions of natural gas, a marketable resource, could save money and increase energy efficiency. This presentation summarizes the major sources and quantity of methane being emitted to the atmosphere for all segments of the U.S. gas industry: production; processing; storage; transmission; and distribution. A description of how those emissions were determined is included here, as well as a discussion of which sources are potential candidates for reducing emissions. (author)

Norcia, J. [Maritimes and Northeast Pipeline, Halifax, NS (Canada)

1998-09-01

A review of Sable Energy Offshore Project`s plans to develop six major gas fields on the Scotian Shelf was presented. The onshore phase of the project consists of Canadian and U.S. main pipelines and laterals to Halifax, Nova Scotia and Saint John, New Brunswick and possibly to other areas in Nova Scotia, New Brunswick and New England. The Sable Offshore Energy Project includes a resource base containing 3.5 trillion cubic feet of natural gas committed to Maritimes and Northeast Pipeline Company. This represents a 25 year supply with an average production of more than 500,000 mmBtu/d. A progress report on the pipeline project was presented. Maritimes and Northeast Pipeline is constructing an underground gas transmission pipeline of about 1,000 km that will transport the Sable natural gas to markets in Nova Scotia, New Brunswick and New England. The total cost of the project has been estimated at $1 billion (Cdn). The pipeline construction will begin in the spring of 1999 to meet the in-service date of November 1999. The Canadian portion of the pipeline consists of 558 km (exclusive of the laterals to Halifax, Saint John and Point Tupper) of 30 inch diameter underground pipe. The U.S. portion will consists of 156 km of 30 inch diameter underground pipe and 306 km of 24 inch diameter underground pipe. Market projections to date include 400,000 mmBtu/d in Canada, and 1,200,000 mmBtu/d in the U.S. market. Distribution franchises are expected to be awarded in 1999. A complete review of the regulatory process was also provided. 1 tab.

U.S. crude oil, natural gas, and natural gas liquids reserves 1995 annual report

NONE

1996-11-01

The EIA annual reserves report series is the only source of comprehensive domestic proved reserves estimates. This publication is used by the Congress, Federal and State agencies, industry, and other interested parties to obtain accurate estimates of the Nation`s proved reserves of crude oil, natural gas, and natural gas liquids. These data are essential to the development, implementation, and evaluation of energy policy and legislation. This report presents estimates of proved reserves of crude oil, natural gas, and natural gas liquids as of December 31, 1995, as well as production volumes for the US and selected States and State subdivisions for the year 1995. Estimates are presented for the following four categories of natural gas: total gas (wet after lease separation), nonassociated gas and associated-dissolved gas (which are the two major types of wet natural gas), and total dry gas (wet gas adjusted for the removal of liquids at natural gas processing plants). In addition, reserve estimates for two types of natural gas liquids, lease condensate and natural gas plant liquids, are presented. Also included is information on indicated additional crude oil reserves and crude oil, natural gas, and lease condensate reserves in nonproducing reservoirs. A discussion of notable oil and gas exploration and development activities during 1995 is provided. 21 figs., 16 tabs.

Natural gas pricing

International Nuclear Information System (INIS)

Freedenthal, C.

1993-01-01

Natural gas pricing is the heart and soul of the gas business. Price specifically affects every phase of the industry. Too low a price will result in short supplies as seen in the mid-1970s when natural gas was scarce and in tight supply. To fully understand the pricing of this energy commodity, it is important to understand the total energy picture. In addition, the effect and impact of world and US economies, and economics in general are crucial to understanding natural gas pricing. The purpose of this presentation will be to show the parameters going into US natural gas pricing including the influence of the many outside industry factors like crude oil and coal pricing, market drivers pushing the gas industry, supply/demand parameters, risk management for buyers and sellers, and other elements involved in pricing analysis

Design of a Natural Gas Liquefaction System with Minimum Components

International Nuclear Information System (INIS)

Bergese, Franco

2004-01-01

In this work an economic method for liquefying natural gas by diminishing its temperature by means of the Joule-Thomson effect is presented.The pressures from and to which the gas must be expanded arose from a thermodynamic calculation optimizing the cost per unit mass of Liquefied Natural Gas LNG).It was determined that the gas should be expanded from 200 atm to 4 atm.This expansion ratio can be used in different scales.Large Scale: liquefaction of gas at well.It takes advantage of the fact that the gas inside the well is stored at high pressure.The gas is expanded in a valve / nozzle and then compressed to the pressure of the local pipeline system.The objective of this project is to export natural gas as LNG, which is transported by ships to the markets of consumption.Using this method of liquefaction, the LNG production levels are limited to a fraction of the production of the well, due to the injection of the un condensed gas into the local pipelines system.Medium Scale: A high pressure pipeline is the source of the gas.The expansion is performed and then the gas is again compressed to the pressure of a lower pressure pipeline into which the gas is injected.The pressure reductions of natural gas are performed nearby big cities.The aim of this project scale is the storage of fuel for gas thermal power plants during periods of low energy consumption for later burning when the resource is limited. Another possibility that offers this size of plant is the transportation of gas to regions where the resource is unavailable.This transportation would be carried out by means of cistern trucks, in the same way that conventional liquid fuels are transported.Small scale: the place of production would be a CNG refueling station. The source of gas is in this case a gas pipeline of urban distribution and the gas should be compressed with the compressor of the refueling station.Compressors have generally low loading factor and the periods of time when they are not producing

Development of natural gas ocean transportation chain by means of natural gas hydrate (NGH)

Nogami, T.; Oya, N.; Ishida, H.; Matsumoto, H.

2008-01-01

Recent studies in Japan have suggested that natural gas hydrate (NGH) transportation of natural gas is more economical than liquefied natural gas (LNG) transportation systems for small, medium and remote gas fields. Researchers in Japan have built a 600 kg per day NGH production and pelletizing plant and regasification facility. This paper discussed feasibility studies conducted in southeast Asia to determine the unit's commercialization potential with large natural gas-related businesses including shipping companies and electric power utilities. The total supply chain was compared with the corresponding liquefied natural gas (LNG) and compressed natural gas (CNG) supply chains. The study also examined natural gas reserves, energy policies, the positioning of natural gas supplies, and future forecasts of natural gas demand. A conceptual design for an NGH supply chain in Indonesia was presented. Results of the study have demonstrated that the NGH chain is an appropriate and economically feasible transportation method for many areas in southeast Asia. 8 refs., 10 figs

Landowner attitudes toward natural gas and wind farm development in northern Pennsylvania

Jacquet, Jeffrey B.

2012-01-01

The US has undergone a recent boom in the development of onshore wind farm and natural gas energy projects and contentious debates over the construction of these projects are common in communities across the US. A survey of landowners in a region of Northern Pennsylvania (N=1028) undergoing simultaneous development of both wind and natural gas development shows that landowners are generally much more polarized and negative towards gas development than wind farm development, and that attitudes toward natural gas development is highly dependent on environmental attitudes and industry leasing, development, or employment experience. Landowner proximity to the development explains a small amount of the variation in attitudes towards wind energy. Recommendations for energy policy and future research are discussed. - Highlight: ► A Pennsylvania survey reveals attitudes toward natural gas and wind development. ► Gas drilling attitudes became more negative; wind farm attitudes more positive. ► Environmental concern and industry experience influence attitudes toward energy. ► Proximity to wind is weakly related to attitudes; proximity to gas is not related.

Investments required for natural gas distribution networks are high. The use of compressed natural gas (CNG) is seen as a way to prepare and develop consuming markets to receive those networks. This paper outlines the socio-economic context and the reasons that motivated the creation of a CNG project in Campina Grande, in the state of Paraiba. Technical aspects of project implementation are described, including difficulties encountered and courses of action undertaken as a result. Other aspects considered include the social and economic impact and local consumer's expectations with the arrival of new fuel. The study also considers factors relevant to the project such as the distance from the pressure measurement and regulation station, transported volumes, technology used, infrastructure and road conditions.

Forecasting: Canada's NGL [natural gas liquids] supply outlook

International Nuclear Information System (INIS)

Anderson, A.B.

1992-01-01

A perspective is given on Canada's supply and demand balance of ethane, propane, and butane, and Canada's participation in meeting the expected increases in United States import requirements. Increases in Canadian natural gas liquids (NGL) supply depends on increases in natural gas production. Since new production (except for the Shell Caroline gas discovery) is tending to have lower yields of liquids, NGL supply will not increase as much as the increase in natural gas production. Nearly 50% of Canadian NGLs are produced in straddle plants located at the inlet of gas transmission lines. Surpluses of ethane and high capital costs means that new straddle plants will not be built in the near future, but expansions of existing plants will occur to maximize propane and butane production. The potential ethane supply will increase, notably from the Shell Caroline project. The primary market for ethane in Canada is the Alberta petrochemical industry, and a new ethylene plant to be started up in 1994 will increase demand. The use of ethane for miscible flooding will decrease to the end of the decade. Propane production is expected to increase to a total of 180,000 bbl/d by 2000; demand growth in traditional markets such as heating and cooking is expected to be marginal, and the petrochemical sector is expected to show the largest growth in propane demand. The use of butane for producing methyl tertiary butyl ether is expected to increase butane demand for the rest of the decade. Exports of NGL to the USA are largely via the Cochin pipeline system. Modest increases in NGL exports are expected. A number of gas pipeline projects are at various stages of planning, and completion of these projects would enable an increase in Canadian exports. 8 figs

Methane emissions from the natural gas industry

Harrison, M.R.; Cowgill, R.M.; Campbell, L.M.; Lott, R.A.

1993-01-01

The U.S. EPA and the United Nation's Intergovernmental Panel on Climate Change (IPCC) have suggested that global warming could be reduced if more energy was generated using natural gas rather than fuels such as coal. An increased use of natural gas instead of coal would decrease global warming since methane emits less carbon dioxide (CO 2 ) than any fossil fuel. However, methane is a more potent as a greenhouse gas than CO 2 , and leakage from the gas system could reduce or eliminate the inherent advantage of natural gas. For this reason, methane emissions must be quantified before a national policy on preferred fuels is developed. Therefore, GRI and EPA have developed this confunded program to quantify methane emissions from the U.S. gas industry. This paper presents, for general industry review, the approach and methodology that the project is using to determine the emissions. The study will measure or calculate all gas industry methane emissions - from production at the wellhead, through the system, to the customer's meter. When these data are combined with data from other studies, a definitive comparison of the relative environmental impact of using methane versus other fuels will be possible. The study will also provide data that can be used by the industry to identify cost-effective mitigation techniques to reduce losses. The methane emissions project is being conducted in three phases: the first two phases have identified and ranked all known potential methane-emitting sources and established methods for measuring, calculating, and extrapolating emissions from those sources. The third phase, which is currently in progress, will gather sufficient data to achieve the accuracy goal. This paper briefly summarizes the methodology being used for the completion of the third phase

Natural gas development in the Russian Far East

Khartukov, E.M.

1994-01-01

The poorly explored and mostly underdeveloped gas resources of the Russian Far East (RFE) are large enough to support several large-scale projects, with an aggregate exportable surplus of up to 30 bcm of natural gas a year. However, owing to the uncertainties of the regional and national investment climate, new development projects, which heavily rely upon invited foreign participation, are likely to be delayed and will hardly yield, by the year 2000, more than 10 bcm of Russian gas for export. Nevertheless, in the forecastable future the region will emerge as an important player in the Asia-Pacific energy market and, consequently, in this area's geopolitical arena as well. (author)

Industrial natural gas consumption in the United States: an empirical model for evaluating future trends

International Nuclear Information System (INIS)

Huntington, H.G.

2007-01-01

This study develops a statistical model of industrial US natural gas consumption based upon historical data for the 1958-2003 period. The model specifically addresses interfuel substitution possibilities and changes in the industrial economic base. Using a relatively simple approach, the framework can be simulated repeatedly with little effort over a range of different conditions. It may also provide a valuable input into larger modeling exercises where an organization wants to determine long-run natural gas prices based upon supply and demand conditions. Projections based upon this demand framework indicate that industrial natural gas consumption may grow more slowly over the next 20 yr than being projected by the U.S. Energy Information Administration (EIA). This conclusion is based upon the assumption that natural gas prices will follow oil prices, as they have done over recent decades. If natural gas prices should lag well below oil prices, as envisioned by the latest EIA outlook, industrial natural gas consumption should rapidly expand well beyond the levels being projected by EIA.

Medium and Long Term Natural Gas Outlook - February 2015

International Nuclear Information System (INIS)

Lecarpentier, Armelle

2015-02-01

World natural gas demand is expected to grow by 1.8%/year over 2013- 2035. Asia-Oceania explains 42% of the incremental demand (China: 28%), followed by the Middle East (24%). Natural gas share in world primary energy supply is projected to increase from an estimated 21.3% in 2013 to 23.6% in 2035 to the detriment of other fossil fuels. Although the expansion of gas demand is spread across all of the main consuming sectors, gas-fired power generation remains the largest contributor to growth. Natural gas production is growing everywhere, with the exception of Europe (-2.1%/year). The largest regional production gains are expected in Asia Oceania, the Middle East and North America. Shale gas will provide one third of the incremental natural gas supply by 2035. In the US, shale gas production will account for 56% of national output by 2035, versus 44% in 2013. Net inter-regional trade is forecast to grow by 3.1%/year to 821 bcm by 2035. The CIS will record the largest volumetric growth in net exports (+ 191 bcm). The share of LNG in net inter-regional flows will increase from 46% in 2013 to 50% in 2035. The international LNG market is expected to tighten after 2020. The price differentials between the US, Europe and Japan will narrow in a context of globalization of gas markets via a strong expansion of the LNG trade (flexible LNG). A number of powerful factors argue in favour of a growing contribution of natural gas to meet the economic, environmental and security challenges of the world energy system. In terms of supply, costly investments must be made to meet future demand, limit tensions on international markets and favour supply security, flexibility and diversification. Despite a growing component of spot indexing in pricing formulas, oil indexing (Asia) and long term contracts will remain necessary to meet the massive investment requirements in new and capital-intensive projects. The competitiveness of natural gas remains a major challenge. The orientation of

LNG [liquefied natural gas]: Fueling energy demand in the Far East

Brown, R.L.

1993-01-01

An overview is presented of the supply and demand outlook for liquefied natural gas (LNG) in the far east, and the basic elements of an LNG supply project in Japan. Power generation is the primary market for LNG in the far east, due to a preference for energy supply diversity, large undeveloped gas resources, drastic improvements in power generation technology, and environmental advantages of natural gas. India and mainland China represent huge potential markets, and projects are under discussion to bring gas by pipeline from Iran or Qatar to both Pakistan or India. The economics of LNG plant development in Japan, including large ($4 billion for field and plant development) capital costs, long-term contracts, government involvement, and gas prices are discussed. Falling yen/dollar exchange rates have substantially bettered the Japanese economy in terms of gas prices. 11 figs., 2 tabs

Economic studies on simulated gas hydrate reservoirs have been compiled to estimate the price of natural gas that may lead to economically viable production from the most promising gas hydrate accumulations. As a first estimate, $CDN2005 12/Mscf is the lowest gas price that would allow economically viable production from gas hydrates in the absence of associated free gas, while an underlying gas deposit will reduce the viability price estimate to $CDN2005 7.50/Mscf. Results from a recent analysis of the simulated production of natural gas from marine hydrate deposits are also considered in this report; on an IROR basis, it is $US2008 3.50-4.00/Mscf more expensive to produce marine hydrates than conventional marine gas assuming the existence of sufficiently large marine hydrate accumulations. While these prices represent the best available estimates, the economic evaluation of a specific project is highly dependent on the producibility of the target zone, the amount of gas in place, the associated geologic and depositional environment, existing pipeline infrastructure, and local tariffs and taxes. ?? 2009 Elsevier B.V.

An economic evaluation of Peru's liquefied natural gas export policy

International Nuclear Information System (INIS)

Leung, Leonard; Jenkins, Glenn P.

2014-01-01

Peru's Camisea gas fields hold nearly 90% of the country's natural gas reserves. In the 1990s, the government had a policy to prioritize Camisea gas for domestic consumption. The revocation of this policy in the 2000s allowed private developers to export 40% of Camisea's proven reserves, equivalent to one third of Peru's total. This USD 3.9 billion liquefied natural gas (LNG) export project boasts the largest single foreign direct investment in Peru's history. A major component of the financing was granted by international financial institutions on economic grounds. While the project was expected to yield a substantial return to private investors, the export of one third of Peru's total proven natural gas reserves is not in line with its long-term interests. We undertake cost–benefit analyses for a series of scenarios, starting with the project's formative stage in the mid-2000s, and then in 2012, two years after it began its commercial operation. In all cases, Peru does not have sufficient reserves to warrant export, and the economic costs far exceed the benefits. This policy of LNG exports should not have been approved by the government, nor should the loans have been granted by international financial institutions to make it possible. - Highlights: • Peru's Liquefied Natural Gas project is creating an economic loss to the country. • Results of our analyses are robust for all scenarios considered. • The present value of the cost of replacing exported energy far exceeds tax revenue. • Projects cannot be approved based only on immediate benefits. • The potential opportunity costs of projects must be considered

Natural gas retailing: writing the last chapter of natural gas deregulation

International Nuclear Information System (INIS)

Bjerkelund, T.

1995-01-01

Under the A greement on Natural Gas Markets and Prices of October 1985, the Canadian federal government agreed to deregulate the price of natural gas and to allow a competitive gas market to develop. Several beneficial changes that have occurred as a result of the deregulation were described, including the Industrial Gas Users Association's (IGUA) view on the marketing and sale of natural gas by local gas distributor's (LDC) and the sale within the LDC franchise. IGUA's support for the separation between LDC distribution and LDC sales and marketing activities as the last step in deregulation process, was explained. Several arguments for the opposing view were also discussed. Recommendations were made for effective separation of LDC distribution and LDC sales/marketing activities

Scenarios for Russia's natural gas exports to 2050

Paltsev, Sergey

2014-01-01

Russia is an important energy supplier as it holds the world's largest natural gas reserves and it is the world's largest exporter of natural gas. Despite a recent reduction in Russia's exports to Europe, it plans to build new pipelines. We explore the long-term (up to 2050) scenarios of Russian natural gas exports to Europe and Asia using the MIT Emissions Prediction and Policy Analysis (EPPA) model, a computable general equilibrium model of the world economy. We found that over the next 20–40 years natural gas can still play a substantial role in Russian exports and there are substantial reserves to support a development of the gas-oriented energy system both in Russia and in its current and potential gas importers. Based on the considered scenarios, Russia does not need any new pipeline capacity to the EU unless it wants to diversify its export routes to supply the EU without any gas transit via Ukraine and Belarus. Asian markets are attractive to Russian gas and substantial volumes may be exported there. Relatively cheap shale gas in China may sufficiently alter the prospects of Russian gas, especially in Asian markets. In the Reference scenario, exports of natural gas grow from Russia's current 7 Tcf to 11–12 Tcf in 2030 and 13–14 Tcf in 2050. Alternative scenarios provide a wider range of projections, with a share of Russian gas exports shipped to Asian markets rising to more than 30% by 2030 and almost 50% in 2050. Europe's reliance on LNG imports increases, while it still maintains sizable imports from Russia. - Highlights: • In the Reference scenario exports of natural gas grow from Russia’s current 7 Tcf to 11–12 Tcf in 2030 and 13–14 Tcf in 2050. • In alternative scenarios a share of Russian exports to Asian markets is rising to about 30% by 2030 and 50 % in 2050. • Cheap shale gas in China can sufficiently alter Russian natural gas export. • Reduction in nuclear generation in Europe can lead to increased exports of natural gas from

Natural gas deregulation

International Nuclear Information System (INIS)

Ronchi, M.

1993-01-01

With the aim of establishing realistic options for deregulation in the natural gas industry, this paper first considers the structural evolution of this industry and evidences how it differs from the petroleum industry with which it exhibits some essential characteristics in common. This comparison is made in order to stress that, contrary to popular belief, that which is without doubt good for the petroleum industry is not necessarily so also for the natural gas industry. The paper concludes with separate analyses of the natural gas markets in the principal industrialized countries. Arguments are provided to show that the 'soft' deregulation option for the natural gas industry is not feasible, and that 'total' deregulation instead, backed by the passing of a suitable package of anti-trust laws 'unbundling' the industry's four major activities, i.e., production, storage, primary and secondary distribution, is the preferable option. The old concept of guaranteed supplies for minor users of natural gas should give way to the laws of supply and demand governing inter-fuel competition ensured through the strict supervision of vigilance committees

Saneev, B.G.; Sokolov, A.D.; Popov, S.P.

2003-01-01

The world natural gas markets are analysed, with a special focus on the countries of Northeast Asia (NEA). The natural gas demands of China, Japan and South Korea, until the year 2020, is projected, considering a possible share of Russian gas. The resource potential of natural gas from the Siberian platform and the Sakhalin shelf is given as a sound basis for fuelling Russia's position in the natural gas market of NEA countries. Development of the powerful gas industry in the East of Russia faces some particular conditions that can decrease the effectiveness of investments. The eastern geopolitical direction is very important for Russia and the necessity to create a favourable political and economic environment for oil and gas export is of prime interest, as stressed in Energy Strategy for Russia till the Year 2020. In this context, the long-term market for natural gas in East Siberia and the Far East of Russia is investigated. Possible routes of natural gas export from Russia to NEA countries include three main directions: to the west of China with connection to the 'West-East gas pipeline', a route through and/or round Mongolia and, finally, a route along the Trans-Siberian or Baikal-Amur railroads to Russian ports in the Far East. As a result of complex studies, three stages in the creation of the unified gas pipeline system are suggested. Evaluation of the investments required for construction of such a natural gas pipeline system, expected gas volumes and prices on the markets show its high economic efficiency. In conclusion, the most valuable ideas are stressed. (author)

Major gas projects in Latin America. Issues and perspectives

International Nuclear Information System (INIS)

Khelil, C.

1997-01-01

The Latin American energy demand will reach 677 MTOE by 2010, a 50% increase over 1995. There will be a major shift towards use of natural gas in power generation. US 503 10 9 Dollars will be required over 1995-2010 to discover and develop hydrocarbon reserves, build the pipeline system as well as generate and distribute electricity. US 19 10 9 Dollars will be required for gas pipelines and LNG projects in the region. Improvements in the policy, legal and regulatory framework are required in many countries to attract the needed investments. Several major gas projects are being implemented or planned in the region: Colombia Enron-built pipeline, Peru Camisea project, Chile Nova gas pipeline from Argentina, the Bolivia-Brazil pipeline and others. The World Bank group has been assisting countries in developing a competitive business environment and can provide, when needed, comfort to lenders in project financing through a guarantee scheme in several large complex cross border projects.

This work reports on the SEGRED project, which aims to develop an expert system for management of natural gas transportation networks. The system is currently being developed by LASHIP-UFSC in partnership with PETROBRAS/CENPES and TBG. The SEGRED system consists of an environment designed to support natural gas pipeline management by means of remote supervision of process parameters and analysis of the mutual interactions of those parameters by an expert system integrated to a dynamic simulator. The system is deployed through a process that contributes to making available for use the knowledge about functions such as line packing analysis and line break detection, thus enhancing the quality of execution of these tasks, which are related to the management of natural gas transportation network. The main benefits consist of promoting efforts to acquire and organize expert knowledge. This process contributes to the generation of a knowledge base with corporate technical memory, which can be made available in a permanent, expansible and useful way for decision-making. (author)

The natural gas industry in Russia: reforms in debate

Locatelli, Catherine

2014-07-01

Due to the emergence of shale gas in the USA, Russia has become the second world producer of natural gas but this industry remains one of the most important sectors of the Russian economy as natural gas exports are an essential component or the Russian economic policy. Addressing this industry, the author first comments the evolutions of gas production since 1960 and its perspectives by 2020 and 2030. He also outlines the importance of the cost issue associated with the choice between mega projects and smaller ones. In a second part, the author comments and discusses the evolutions of gas exports towards Europe and of the export strategy. He evokes the possibility of arbitration between price and quantity in Gazprom's strategy, the possibility of a strategy of downstream integration on European gas markets, the possibility of a diversification of export markets (notably LNG markets as several LNG projects are planned). In the third part, the author describes the Gazprom model, comments the recurring debate on a reform of this holding, and discusses its quantity-based management and the issue of Gazprom's efficiency. He briefly evokes the issue of reform of the Russian gas industry, the progressive emergence of new actors

Canada's natural gas industry enjoys a quiet confidence as it looks ahead to the 1990s. In this paper, the author explains why, despite some critical uncertainties, the optimism endures. Reviewing the current conditions of supply, production, consumption, pipelines, and pipeline expansion plans, the author contends that the New World of the 1990s will belong to natural gas. The author's assessment of natural gas markets proceeds far beyond the borders of Canada. The author examines the determinants of gas prices throughout North America and he identifies the one force that promises to seize almost complete control of gas prices throughout the continent. While the analysis points out the attributes of this new pricing regime, it also names the obstacles that could prevent this emerging mechanism from assuming its anticipated position

The natural gas purification and pipeline sector is a major economic driver in Canada. Gas processing facilities are growing in number, and several large gas projects are being planned for future construction in the western provinces. This article outlined 5 gas plants in order to illustrate the sector's history and breadth in Canada. The Shell Jumping Pound gas complex was constructed in 1951 after a sulfur-rich gas discovery near Calgary in 1944. The Empress Straddle plant was built in 1971 in southeastern Alberta and is one of the largest single industrial consumers of electrical power in the province. The Fort Nelson gas processing plant is North America's largest sour gas processing facility. The Shell Caroline complex was built 1993. The Sable offshore energy project is located on the coast of Nova Scotia to handle gas produced from the Thebaud wells. A consortium is now considering the development of new gas fields in the Sable area. 5 figs.

Developments on the European energy market. Part 1. Natural gas supply. Extra import covers growing natural gas demand in Europe

International Nuclear Information System (INIS)

Van Gelder, J.W.

2000-01-01

This first part of a series on developments in the European gas market features the growth in gas supply. 35% of the gas demand must be covered from sources outside Europe. For the future additional imports are required from countries such as the Russian Federation, Algeria and Nigeria. Over the next few years the artificial link between ga and oil prices will disappear, bringing the gas price to a structurally lower level. It will be of crucial importance that gas suppliers will not be able to form cartels to keep prices high. All competing projects will curb price increases on the European market, but will definitely result in more freedom of choice for European natural gas consumers

Growing natural gas usage

Saarni, T.

1996-01-01

Finnish natural gas usage topped the 3.3 billion cubic metre mark last year, up 3.6 % on the 1994 figure. Growth has increased now for 12 years in a row. Thanks to offtake by large individual users, the pipeline network has been expanded from South-East Finland to the Greater Helsinki area and central southern Finland. Natural gas plays a much larger role in this region than the 10 % accounted for by natural gas nationally would indicate. The growth in the share of Finland's energy use accounted for by natural gas has served to broaden the country's energy supply base. Natural gas has replaced coal and oil, which has considerably reduced the level of emissions resulting form energy generation

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

International Nuclear Information System (INIS)

1991-09-01

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

The ownership structure of Finland's leading natural gas company, Gasum, changed fundamentally in 1999, and the company is now no longer a subsidiary of Fortum Corporation. 'Our new strong and broad ownership base will enable us to develop the natural gas business and pipeline network in Finland in response to the requirements of our Finnish customers', says Antero Jaennes, Gasum's Chairman and CEO, who stresses that Gasum is committed to remaining the leading developer of the Finnish natural gas market and the number-one gas supplier. Natural gas usage in Finland in 1999 totalled 3.9 billion m 3 (38.7 TWh), unchanged from 1998. Natural gas accounted for 11% of Finland's total primary energy need, as it did in 1998. The proportion of natural gas used in district heating rose by 2% to 36%, and moved down 2% in power generation to 10%. Industry's use of natural gas fell 1% to 17%. 75% of natural gas was used in combined heat and power (CHP) generation in industry and district heating. In 2000, Gasum expects to sell 4 billion m 3 of natural gas (40 TWh)

The study utilizes a hierarchical approach including (1) comparative analyses of different energy chains, (2) specific evaluations for the natural gas chain, and (3) a detailed overview of the German situation, based on an extensive data set provided by Deutsche Vereinigung des Gas- und Wasserfaches (DVGW). According to SVGW-expertise DVGW-data can be regarded as fully representative for Swiss conditions due to very similar technologies, management, regulations and safety culture, but has a substantially stronger statistical basis because the German gas grid is about 30 times larger compared to Switzerland. Specifically, the following tasks were carried out by PSI to accomplish the objectives of this project: (1) Consolidation of existing ENSAD data, (2) identification and evaluation of additional sources, (3) comparative assessment of accident risks, and (4) detailed evaluations of specific issues and technical aspects for severe and smaller accidents in the natural gas chain that are relevant under Swiss conditions.

Natural gas is more than gas power plants

International Nuclear Information System (INIS)

Lind, Oddvar

2000-01-01

Through the Statpipe gas line at Karmoey, Norway supplies 20% of the natural gas on the European market. The pipeline is 'leaking' a little bit of gas to the local communities at Karmoey and Haugesund. These communities have replaced 65% of their oil consumption with natural gas, which is a fine contribution to a better environment. The supplier of the natural gas, Gasnor ASA in this case, claims an energy efficiency of 90% at the end user because the gas burns directly and the loss in the pipeline is minimal. The efficiency of natural gas utilisation is twice that of the planned gas power stations in West-Norway, subtracting the losses in the electrical network. Gasnor ASA competes with oil suppliers and, if necessary, with electric utilities. The county hospital at Haugesund is quoted as an example. The hospital has two large boilers with dual fuel burners. They have been using natural gas since 1998 because it was worth while both economically and environmentally. The use of natural gas in the transport sector would be very important, but the necessary infrastructure is very little developed. For instance, five diesel-powered ferries on the Boknafjord emit as much NOx as the planned gas power plant at Kaarstoe

Girish Srinivas; Steven C. Gebhard; David W. DeBerry

2001-01-01

This first quarter report of 2001 describes progress on a project funded by the U.S. Department of Energy (DOE) to test a hybrid sulfur recovery process for natural gas upgrading. The process concept represents a low cost option for direct treatment of natural gas streams to remove H(sub 2)S in quantities equivalent to 0.2-25 metric tons (LT) of sulfur per day. This process is projected to have lower capital and operating costs than the competing technologies, amine/aqueous iron liquid redox and amine/Claus/tail gas treating, and have a smaller plant footprint, making it well suited to both on-shore and offshore applications. CrystaSulf(trademark) (service mark of Gas Research Institute) is a new nonaqueous sulfur recovery process that removes hydrogen sulfide (H(sub 2)S) from gas streams and converts it into elemental sulfur. CrystaSulf features high sulfur recovery similar to aqueous-iron liquid redox sulfur recovery processes, but differs from the aqueous processes in that CrystaSulf controls the location where elemental sulfur particles are formed. In the hybrid process, approximately 1/3 of the total H(sub 2)S in the natural gas is first oxidized to SO(sub 2) at low temperatures over a heterogeneous catalyst. Low temperature oxidation is done so that the H(sub 2)S can be oxidized in the presence of methane and other hydrocarbons without oxidation of the hydrocarbons. The project involves the development of a catalyst using laboratory/bench-scale catalyst testing, and then demonstration of the catalyst at CrystaTech's pilot plant in west Texas. During this reporting periods new catalyst formulations were tested. The experiments showed that the newest catalyst has slightly better performance, but catalyst TDA No.2 is still superior overall for use with the hybrid CrystaSulf process due to lower costs. Plans for catalyst pelletization and continued testing are described

Full Text Available The largest reserves of natural gas worldwide are found in regions far of main cities, being necessary different alternatives to transport the fluid to the consumption cities, such as pipelines, CNG or ships, LNG, depending on distances between producing regions and demanding regions and the producing volumes. Consumption regions have three different markets to naturalgas; residential and commercial, industrial and power generation sector. The residential and commercial is highly seasonal and power generation sector is quite variable depending on increases of temperature during summer time. There are also external issuesthat affect the normal gas flow such as fails on the national system or unexpected interruptions on it, what imply that companies which distribute natural gas should design plans that allow supplying the requirements above mentioned. One plan is using underground natural gas storage with capacities and deliverability rates enough to supply demands. In Colombia there are no laws in this sense but it could be an exploration to discuss different ways to store gas either way as underground natural gas storage or above superficies. Existing basically three different types of underground natural gas storage; depleted reservoirs, salt caverns and aquifers. All ofthem are adequate according to geological characteristics and the needs of the distributors companies of natural gas. This paper is anexploration of technical and economical characteristics of different kind of storages used to store natural gas worldwide.

The National Energy Board monitors the supply of all energy commodities in Canada along with the demand for Canadian energy commodities in domestic and export markets. This report provides an assessment of the natural gas market in British Columbia (BC) and discusses several issues facing the market. The main challenges facing the market in recent years have been rising prices, price spikes and increased price volatility. New exploration and development projects have been announced along with new gas pipeline projects that move gas to eastern markets. Industrial consumers are exploring fuel alternatives to reduce natural gas consumption. Despite these challenges, the Board believes the natural gas market in British Columbia is working well. Natural gas prices are integrated with the North American market, consumers have responded to higher prices by reducing demand, and producers have increased exploration and production. Price discovery has improved due to better pricing reporting standards and access to electronic gas trading at pricing points for BC gas. The small market size in British Columbia and the lack of storage in the Lower Mainland limit market liquidity in comparison with other major market centres. 20 figs

Natural Gas Imports and Exports. Third Quarter Report 1999

The second quarter 1997 Quarterly Report of Natural Gas Imports and Exports featured a Quarterly Focus report on cross-border natural gas trade between the United States and Mexico. This Quarterly Focus article is a follow-up to the 1997 report. This report revisits and updates the status of some of the pipeline projects discussed in 1997, and examines a number of other planned cross-border pipeline facilities which were proposed subsequent to our 1997 report. A few of the existing and proposed pipelines are bidirectional and thus have the capability of serving either Mexico, or the United States, depending on market conditions and gas supply availability. These new projects, if completed, would greatly enhance the pipeline infrastructure on the U.S.-Mexico border and would increase gas pipeline throughput capacity for cross-border trade by more than 1 billion cubic feet (Bcf) per day. The Quarterly Focus is comprised of five sections. Section I includes the introduction as well as a brief historic overview of U.S./Mexican natural gas trade; a discussion of Mexico's energy regulatory structure; and a review of trade agreements and a 1992 legislative change which allows for her cross-border gas trade in North America. Section II looks at initiatives that have been taken by the Mexican Government since 1995to open its energy markets to greater competition and privatization. Section III reviews Mexican gas demand forecasts and looks at future opportunities for U.S. gas producers to supplement Mexico's indigenous supplies in order to meet the anticipated rapid growth in demand.

Short-term outlook for natural gas and natural gas liquids to 2006 : an energy market assessment

International Nuclear Information System (INIS)

2005-10-01

In recent years, natural gas markets in North America have seen a close balance between supply and demand, resulting in high and volatile natural gas prices. The National Energy Board monitors the supply of all energy commodities in Canada along with the demand for Canadian energy commodities in domestic and export markets. This is the NEB's first energy market assessment report that presents a combined short-term analysis and outlook of natural gas and natural gas liquids (NGLs), such as ethane, propane and butane. It provides comprehensive information on the complexity of natural gas and NGL industries and highlights recent developments and topical issues. As a major producer of natural gas, western Canada has a correspondingly large natural gas processing capability that was developed specifically to extract NGLs. A world-scale petrochemical industry was developed in Alberta to convert NGLs into even higher valued products such as ethylene. Since NGLs in Canada are sourced mostly from natural gas, changes to the supply and demand for natural gas would impact NGL supply. This report addressed the issue of commodity prices with reference to crude oil, natural gas and NGL prices. Natural gas supply in terms of North American production and natural gas from coal (NGC) was also reviewed along with natural gas demand for residential and commercial heating, industrial use, power generation, and enhanced recovery for oil sand operations. There are about 692 gas plants in Canada that process raw natural gas into marketable gas and NGLs. Most are small field plants that process raw natural gas production to remove impurities such as sulphur, water and other contaminants. This report also discussed this infrastructure, with reference to field plants, straddle plants, pipelines, distribution and storage, including underground NGL storage. 3 tabs., 27 figs., 5 appendices

Allison, E.

2009-01-01

This presentation discussed the impacts of imports, government policy and technology on future natural gas supply. Specifically, it discussed projections of natural gas supply and demand; the potential impact of imports on United States natural gas supply; the potential impacts of government policy on natural gas supply and demand; and the impact of technological innovations on natural gas supply such as coalbed methane and methane hydrate. Specific government policies that were examined included the American Recovery and Reinvestment Act of 2009; the American Clean Energy and Security Act of 2009; and the Clean Energy Jobs and American Power Act of 2009. It was concluded that the United States demand for natural gas will expand and that the impact of pending clean energy legislation is unclear. In addition, each potential future resource will face constraints and new resources may come on line in the next 20 years. figs.

Only one percent of the natural gas from the Norwegian gas fields is currently used in Norway and it is a national goal that 10 percent of the gas produced shall be used for domestic purposes. Western Norway should pioneer this development, as this is where the gas is brought on land. ''Vestlandsroeret AS'' is a project in which sixteen municipalities - including the city Bergen - and eleven companies plan to develop infrastructure which will provide for transport of the gas to customers and markets in Western Norway. The article also discusses environmental considerations, public opinion, the utilization of waste heat and extensive development of cod culture

Reynolds, D. B.; Kolodziej, M.

2009-01-01

In this article, the U.S. and southern Canadian natural gas supply market is considered. An important model for oil and natural gas supply is the Hubbert curve. Not all regions of the world are producing oil or natural gas following a Hubbert curve, even when price and market conditions are accounted for. One reason is that institutions are affecting supply. We investigate the possible effects of oil and gas market institutions in North America on natural gas supply. A multi-cycle Hubbert curve with inflection points similar to the Soviet Union's oil production multi-cycle Hubbert curve is used to determine North American natural gas discovery rates and to analyze how market specific institutions caused the inflection points. In addition, we analyze the latest shale natural gas projections critically. While currently, unconventional resources of natural gas suggest that North American natural gas production will increase without bound, the model here suggests a peak in North American natural gas supplies could happen in 2013.

A method of natural gas liquefaction may include cooling a gaseous NG process stream to form a liquid NG process stream. The method may further include directing the first tail gas stream out of a plant at a first pressure and directing a second tail gas stream out of the plant at a second pressure. An additional method of natural gas liquefaction may include separating CO.sub.2 from a liquid NG process stream and processing the CO.sub.2 to provide a CO.sub.2 product stream. Another method of natural gas liquefaction may include combining a marginal gaseous NG process stream with a secondary substantially pure NG stream to provide an improved gaseous NG process stream. Additionally, a NG liquefaction plant may include a first tail gas outlet, and at least a second tail gas outlet, the at least a second tail gas outlet separate from the first tail gas outlet.

Hydroxyl-Containing Aromatic Polyimides for Carbon Dioxide Removal from Natural Gas

KAUST Repository

Alaslai, Nasser Y.

2017-10-01

Natural gas is among the most dominant resources to provide energy supplies and Saudi Arabia ranks among the top 5 producers worldwide. However, prior to use of methane, natural gas has to be treated to remove other feed gas components, such as H2O, CO2, H2S, N2 and C2+ hydrocarbons. Most NG fields in KSA contain about 10 mol% carbon dioxide that has to be reduced to less than 2 mol% for pipeline delivery. The conventional unit operations for natural gas separations, that is, molecular sieves, amine absorption, cryogenic distillation, and turbo expansion exhibit some disadvantages in terms of economics, operational flexibility or system footprint. One of the most attractive alternative is membrane technology in either standalone- or hybrid system configuration. Currently, the only two membrane materials used in industrial natural gas applications are cellulose acetate and polyimide, which have moderate permeability and fairly low selectivity when tested under realistic industrial conditions. The goal for future research is to develop unique polymeric membranes, which can at least partially replace conventional gas processing in future natural gas projects. This will support global economics and specifically the economy of Saudi Arabia. Newly developed polymeric materials must meet certain criteria to be used on a commercial scale. These criteria include: (i) high permeability and selectivity, (ii) processability into thin films, (iii) mechanical and thermal stability, and (iv) chemical stability against feed gas components. This project focused on the removal of carbon dioxide from natural gas by developing and characterizing functionalized aromatic polyimide membrane materials that exhibit very high selectivity under aggressive mixed-gas conditions. 6FDA-DAR demonstrated a mixed-gas CO2/CH4 selectivity of 78 at a CO2 partial pressure of 10 bar with no pronounced indication of plasticization.

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

The United States relies on natural gas for one-quarter of its energy needs. In 2001 alone, the nation consumed 21.5 trillion cubic feet of natural gas. A large portion of natural gas pipeline capacity within the United States is directed from major production areas in Texas and Louisiana, Wyoming, and other states to markets in the western, eastern, and midwestern regions of the country. In the past 10 years, increasing levels of gas from Canada have also been brought into these markets (EIA 2007). The United States has several major natural gas production basins and an extensive natural gas pipeline network, with almost 95% of U.S. natural gas imports coming from Canada. At present, the gas pipeline infrastructure is more developed between Canada and the United States than between Mexico and the United States. Gas flows from Canada to the United States through several major pipelines feeding U.S. markets in the Midwest, Northeast, Pacific Northwest, and California. Some key examples are the Alliance Pipeline, the Northern Border Pipeline, the Maritimes & Northeast Pipeline, the TransCanada Pipeline System, and Westcoast Energy pipelines. Major connections join Texas and northeastern Mexico, with additional connections to Arizona and between California and Baja California, Mexico (INGAA 2007). Of the natural gas consumed in the United States, 85% is produced domestically. Figure 1.1-1 shows the complex North American natural gas network. The pipeline transmission system--the 'interstate highway' for natural gas--consists of 180,000 miles of high-strength steel pipe varying in diameter, normally between 30 and 36 inches in diameter. The primary function of the transmission pipeline company is to move huge amounts of natural gas thousands of miles from producing regions to local natural gas utility delivery points. These delivery points, called 'city gate stations', are usually owned by distribution companies, although some are owned by

The technologies and practices that have enabled the recent boom in shale gas production have also brought attention to the environmental impacts of its use. Using the current state of knowledge of the recovery, processing, and distribution of shale gas and conventional natural gas, we have estimated up-to-date, life-cycle greenhouse gas emissions. In addition, we have developed distribution functions for key parameters in each pathway to examine uncertainty and identify data gaps - such as methane emissions from shale gas well completions and conventional natural gas liquid unloadings - that need to be addressed further. Our base case results show that shale gas life-cycle emissions are 6% lower than those of conventional natural gas. However, the range in values for shale and conventional gas overlap, so there is a statistical uncertainty regarding whether shale gas emissions are indeed lower than conventional gas emissions. This life-cycle analysis provides insight into the critical stages in the natural gas industry where emissions occur and where opportunities exist to reduce the greenhouse gas footprint of natural gas.

Turkey is an important candidate to be the 'energy corridor' in the transmission of the abundant oil and natural gas resources of the Middle East and Middle Asia countries to the Western market. Furthermore, Turkey is planning to increase its oil and gas pipeline infrastructure to accommodate its increased energy consumption. Naturally, Turkish natural gas usage is projected to increase remarkably in coming years, with the prime consumers, expected to be industry and power plants. Energy demand of Turkey is growing by 8% annually, one of the highest rates in the world. In addition, natural gas consumption is the fastest growing primary energy source in Turkey. Gas sales started at 0.5 bcm (billion cubic meters), in 1987 and reached approximately 22 bcm in 2003. This article deals with energy policies and natural gas consumption of Turkey. Besides modernization of present lines and realization of capacity increase, new lines will also be needed. In this context, Turkey, due to its geographical location is, in an important position to vary European supply. Therefore, Turkey's role as a transitory area gains importance.

Ideal-gas thermodynamic properties for natural-gas applications

Calculating caloric properties from a thermal equation of state requires information such as isobaric heat capacities in the ideal-gas state as a function of temperature. In this work, values for the parameters of the c p o correlation proposed by Aly and Lee were newly determined for 21 pure gases which are compounds of natural gas mixtures. The values of the parameters were adjusted to selected c p o data calculated form spectroscopic data for temperatures ranging from 10 to 1000 K. The data sources used are discussed and compared with literature data deduced from theoretic models and caloric measurements. The parameters presented will be applied in a current GERG project for evaluating equations of state (e.g., the AGA 8 equation) for their suitability for calculating caloric properties

Changes in our electricity systems provoked by natural gas power generation technology are paving the way for large-scale renewables use in the future. Natural gas and gas turbines are now such a cheap and easy option for electricity generation that they appear to cast a pall over renewables. The market share of gas-fired generation continues expanding inexorably. Its cost continues to fall, setting renewables an ever more demanding competitive target. Nevertheless, paradoxical though this may sound, natural gas is actually the natural ally of renewables. Despite the fierce competitive challenge it represents, natural gas may even be the most important single factor shaping a bright future for renewables. (author)

Southwest British Columbia natural gas supply and deliverability: Discussion paper

International Nuclear Information System (INIS)

1994-02-01

A review is presented of energy in British Columbia, the role of natural gas, and options available to enhance gas supply security in the province's most densely populated area, the southwest. British Columbia has abundant natural gas supplies, and production exceeds domestic demand. In 1992, natural gas supplied ca 25% of total provincial end-use energy requirements, but this share is expected to rise to 30% by 2015. Although some say that the province's natural gas production and transmission system should serve only domestic needs, this would have significant negative impacts. Domestic gas supply policy allows gas consumers to contract their own supplies, but contract security is required. Provincial guidelines allow demand-side programs to compete with supply sources to ensure that the resource profile is achieved at least cost. In the southwest, natural gas demand is projected to increase from 189 PJ in 1991 to 262 PJ by 2005. Most gas supplied to this region comes from northeast British Columbia through pipelines that are generally fully contracted. Short-term deliverability can be a problem, especially in peak winter demand periods. The gas industry's contingency plans for shortages are outlined and alternatives to enhance deliverability to the southwest are assessed, including storage, expansion of the pipeline system, supply curtailment, and peaking supply contracts. Aspects of provincial natural gas planning are discussed, including security of supply and deliverability, economic and environmental impacts, consumer costs, safety, and the public interest. A least-cost option for enhancing deliverability (underground storage and an additional liquefied natural gas plant) is estimated to cost consumers $3.69/GJ over 20 years. 9 figs., 1 tab

Liquefied natural gas : a Canadian perspective : an energy market assessment

International Nuclear Information System (INIS)

2009-01-01

World requirements for energy and natural gas are expected to increase in the near future. This energy market assessment presented an overview of global liquefied natural gas (LNG) supply and demand, and discussed the potential effects that imported LNG may have on Canadian gas markets and energy infrastructure. Regasification projects will double the world's existing LNG receiving capacity by 2015. However, LNG pricing will still be indexed to the price of crude oil and oil products in the future. LNG price differences will affect trading opportunities as well as the flow of LNG between regions. North American LNG facility development will be influenced by outlooks for continental gas supply and demand. Current declines combined with recent increases in United States natural gas production from unconventional gas resources will reduce requirements for LNG in the near future, and may have a significant impact on long-term North American and global LNG requirements. Canada's existing facilities are located competitively with other terminals. 33 figs.

Although natural gas as a car fuel is a more environmentally clean alternative to gasoline or diesel and gas is considerable cheaper and much safer than other fuels, costumers are still suspicious of alternative fuels and vehicles. The main reasons are a lack of awareness and information on the consumer side, as well as a low information and acceptance level among car dealers and service stations. Therefore the MADEGASCAR project directly addresses major barriers by specific actions. The project MADEGASCAR (Market development for gas driven cars including supply and distribution of biogas), co-funded by the Intelligent Energy Europe programme of the European commission, aims at developing the market for natural gas vehicles by addressing target groups at the demand side (private car owners, fleet managers) as well as strengthening the supply and distribution infrastructure for Compressed Natural Gas (CNG) and Natural Gas Vehicles (NGVs) municipalities, car dealers, owners of fuel stations, natural gas and biogas suppliers) in 10 participating partner countries. The Unique Selling Point of the MADEGASCAR project is deployment in several regional areas instead of sole basic research. Country specific action plans, which are developed and implemented in the project, will have direct impact on regional markets but also affect car manufacturers and national regulations, resulting in long term changes. The main ambition of the MADEGASCAR project is to increase the number of gas vehicles in the partner regions by 50%.

Technical review of coal gasifiers for production of synthetic natural gas

International Nuclear Information System (INIS)

Lee, Geun Woo; Shin, Yong Seung

2012-01-01

Because of the increasing cost of oil and natural gas, energy production technologies using coal, including synthetic natural gas (SNG) and integrated gasification combined cycle (IGCC), have attracted attention because of the relatively low cost of coal. During the early stage of a project, the developer or project owner has many options with regard to the selection of a gasifier. In particular, from the viewpoint of feasibility, the gasifier is a key factor in the economic evaluation. This study compares the technical aspects of gasifiers for a real SNG production project in an early stage. A fixed bed slagging gasifier, wet type entrained gasifier, and dry type entrained gasifier, all of which have specific advantages, can be used for the SNG production project. Base on a comparison of the process descriptions and performances of each gasifier, this study presents a selection guideline for a gasifier for an SNG production project that will be beneficial to project developers and EPC (Engineering, Procurement, Construction) contractors

An Economic Evaluation of Onshore and Floating Liquefied Natural Gas Receiving Terminals: the Case Study of Indonesia

Indonesia has abundant natural gas resources, however the primary fuel used for electricity generation is coal and oil. Insufficient natural gas infrastructure with-in the country acts as a barrier to increased natural gas usage. In Indonesia LNG is the most efficient and effective method for distributing natural gas given the difficult geographical conditions, the world’s largest archipelago and located in a deep sea area. The Government is planning to initiate natural gas imports by 2019 to meet the country’s energy demands. In order to allocate adequate amounts of natural gas across the geographic regions Indonesia must build more LNG regasification terminals. The Indonesia government has not yet determined if the additional regasification terminals will be floating or land-based facilities. This paper assesses the two options and identifies which facility attains greater profitability. The financial analysis of investing in the Sorong LNG regasification terminal project is conducted using NPV, IRR, and sensitivity analysis. This analysis demonstrates that FSRU facilities have greater economic viability than onshore LNG regasification facilities. The FSRU project earns greater than a 12% IRR as compared to a negative IRR earned by an onshore project. The government can make the onshore projects viable by increasing the sales fee from US10.00/MMBTU to US10.60/MMBTU.

Natural gas prices

International Nuclear Information System (INIS)

Johnson, W.A.

1990-01-01

Since the 1970s, many electric utilities and industrial boiler fuel users have invested in dual fuel use capability which has allowed them to choose between natural gas, residual fuel oil, and in some instances, coal as boiler fuels. The immediate reason for this investment was the need for security of supply. Wellhead regulation of natural gas prices had resulted in shortages during the 1970s. Because many industrial users were given lowest priority in pipeline curtailments, these shortages affected most severely boiler fuel consumption of natural gas. In addition, foreign supply disruptions during the 1970s called into question the ready availability of oil. Many boiler fuel users of oil responded by increasing their ability to diversify to other sources of energy. Even though widespread investment in dual fuel use capability by boiler fuel users was initially motivated by a need for security of supply, perhaps the most important consequence of this investment was greater substitutability between natural gas and resid and a more competitive boiler fuel market. By the early 1980s, most boiler fuel users were able to switch from one fuel to another and often did for savings measured in pennies per MMBtu. Boiler fuel consumption became the marginal use of both natural gas and resid, with coal a looming threat on the horizon to both fuels

As an alternative fuel, natural gas is generally accepted for internal combustion engines and some developments have been conducted in order to adopt it for the road vehicles and stationary applications. Foresights shows natural gas vehicles will be a part of the future transportation technology regarding to their mid and long-term benefits. Therefore inherent problems of natural gas engine technology should be overcome to produce a competitive engine. In this paper major problems and their possible solutions in developing and producing natural gas engine for passenger cars are detailed and discussed. Challenging materials are sorted and presented in two categorizes: technical and econo-strategical problems. In the technical section major difficulties faced in components or systems of natural gas engine are analysed in different aspects of design, validation, and production. In addition problems arisen from the fuel characteristics which influence the function and durability of engine are argued. Subjects like freezing in gas regulator, cold start fuel injection, gas leakage, impurities within compressed natural gas, variation in fuel composition, thermo-mechanics of cylinder head and block, wear of valve seat inserts, spark plug erosion, back-fire phenomenon, engine oil quality requirement, low power density and mileage are described. In the econo-strategical discussion, challenges like limited gas distribution infrastructure, lack of specific manufacturing standards and codes, and non-dedicated emission standards are explained. In both part of the paper a comprehensive view is extended to clarify the effect, risk and solutions of each problem. Due to the fact that almost all information and analysis presented in this paper are based on the experience of developing a natural gas engine family, and an extensive literature review, discussions and conclusions could be useful as a guide line for future natural gas engine projects.

Short-term Canadian natural gas deliverability 2006-2008 : an energy market assessment

International Nuclear Information System (INIS)

2006-10-01

This report presented an assessment of the expected capability of Canadian gas production through to the year 2008. Strong natural gas prices have led to record drilling levels in Canada's natural gas industry. North American natural gas prices reached a peak near the end of 2005. The rise in prices during 2005 reflected high world crude oil prices, a tight balance between natural gas supply and demand, and disruptions to United States gas supply from 2 hurricanes. In response to rising prices, western Canada drilling activity achieved new highs in early 2006. Higher drilling rates also reflected rising costs for key inputs of steel, fuel, and labour. Gas prices have since softened due to a storage overhang resulting from a mild winter. The combination of rising costs and softening prices has impacted margins for Canadian gas producers. In response, some producers have reduced drilling expansion plans in coalbed methane (CBM) and shallow gas plays in the Western Canadian Sedimentary Basin (WCSB). Increases in deeper gas drilling have been maintained. Total gas drilling for 2006 is expected to rise by 3 per cent compared to 2005. The report projected a small increase in Canada's total annual gas production from 484 million m 3 /d in 2005 to 491 million m 3 /d in 2008. Annual average deliverability of conventional gas is expected to decline slightly over the projection period. The decrease is expected to be more than offset by growth in CBM production in western Canada, which is expected to increase from 8 million m 3 /d in 2005 to 27 million m 3 /d in 2008. 5 tabs., 5 figs

A major goal of industry and the U.S. Department of Energy (DOE) fossil energy program is to increase gas reserves in tight-gas reservoirs. Infill drilling and hydraulic fracture stimulation in these reservoirs are important reservoir management strategies to increase production and reserves. Phase II of this DOE/cooperative industry project focused on optimization of infill drilling and evaluation of hydraulic fracturing in naturally-fractured tight-gas reservoirs. The cooperative project involved multidisciplinary reservoir characterization and simulation studies to determine infill well potential in the Mesaverde and Dakota sandstone formations at selected areas in the San Juan Basin of northwestern New Mexico. This work used the methodology and approach developed in Phase I. Integrated reservoir description and hydraulic fracture treatment analyses were also conducted in the Pecos Slope Abo tight-gas reservoir in southeastern New Mexico and the Lewis Shale in the San Juan Basin. This study has demonstrated a methodology to (1) describe reservoir heterogeneities and natural fracture systems, (2) determine reservoir permeability and permeability anisotropy, (3) define the elliptical drainage area and recoverable gas for existing wells, (4) determine the optimal location and number of new in-fill wells to maximize economic recovery, (5) forecast the increase in total cumulative gas production from infill drilling, and (6) evaluate hydraulic fracture simulation treatments and their impact on well drainage area and infill well potential. Industry partners during the course of this five-year project included BP, Burlington Resources, ConocoPhillips, and Williams.

This article presents the experimental results that validate the operation of a new refrigerator in sorption cycle that uses natural gas as its heat source. The project was financed by the RedeGasEnergia of the Petroleo Brasileiro Company - PETROBRAS and by Brazilian agency Agencia Brasileira Financiadora de Estudos e Projetos - FINEP. The refrigeration cycle has two phases: heating/desorption and cooling/adsorption. The materials used were the zeolite 13X and water. The system components, designed for this project, were: two adsorbers, two burners, one condenser and one evaporator. In the heating phase, the burners were turned on to heat up the adsorbers. The adsorbate was released in the vapor phase e flew to the condenser. After its condensation, the liquid moved by the action of gravity to the evaporator. When the burners were turned off, the adsorbers started to cool down due to natural convection and radiation to the ambient. With the decrease of temperature in the adsorbers, the adsorption process began and temperatures below 0 deg C (ice making) were measured in the evaporator. The equipment showed good thermal performance and temperatures near -4 deg C were measured in the evaporator. To produce 5 kg of ice, 0,123 kg of natural gas was used. (author)

Natural gas productive capacity for the lower 48 states 1984 through 1996, February 1996

International Nuclear Information System (INIS)

1996-01-01

This is the fourth wellhead productive capacity report. The three previous ones were published in 1991, 1993, and 1994. This report should be of particular interest to those in Congress, Federal and State agencies, industry, and the academic community, who are concerned with the future availability of natural gas. The EIA Dallas Field Office has prepared five earlier reports regarding natural gas productive capacity. These reports, Gas Deliverability and Flow Capacity of Surveillance Fields, reported deliverability and capacity data for selected gas fields in major gas producing areas. The data in the reports were based on gas-well back-pressure tests and estimates of gas-in-place for each field or reservoir. These reports use proven well testing theory, most of which has been employed by industry since 1936 when the Bureau of Mines first published Monograph 7. Demand for natural gas in the United States is met by a combination of natural gas production, underground gas storage, imported gas, and supplemental gaseous fuels. Natural gas production requirements in the lower 48 States have been increasing during the last few years while drilling has remained at low levels. This has raised some concern about the adequacy of future gas supplies, especially in periods of peak heating or cooling demand. The purpose of this report is to address these concerns by presenting a 3-year projection of the total productive capacity of natural gas at the wellhead for the lower 48 States. Alaska is excluded because Alaskan gas does not enter the lower-48 States pipeline system. The Energy Information Administration (EIA) generates this 3-year projection based on historical gas-well drilling and production data from State, Federal, and private sources. In addition to conventional gas-well gas, coalbed gas and oil-well gas are also included

Natural gas vehicles in Italy

International Nuclear Information System (INIS)

Mariani, F.

1991-01-01

The technology of compressed natural gas (CNG) for road vehicles originated 50 years ago in Italy, always able to adapt itself to changes in energy supply and demand situations and national assets. Now, due to the public's growing concern for air pollution abatement and recent national energy policies calling for energy diversification, the commercialization of natural gas road vehicles is receiving new momentum. However, proper fuel taxation and an increased number of natural gas distribution stations are required to support this growing market potential. Operators of urban bus fleets stand to gain substantially from conversion to natural gas automotive fuels due to natural gas being a relatively cheap, clean alternative

Natural gas consumption and economic growth: Are we ready to natural gas price liberalization in Iran?

International Nuclear Information System (INIS)

Heidari, Hassan; Katircioglu, Salih Turan; Saeidpour, Lesyan

2013-01-01

This paper examines the relationship between natural gas consumption and economic growth in Iran within a multivariate production model. We also investigate the effects of natural gas price on its consumption and economic growth using a demand side model. The paper employs bounds test approach to level relationship over the period of 1972–007. We find evidence of bidirectional positive relationship between natural gas consumption and economic growth in short-run and long-run, based on the production model. The findings also suggest that real GDP growth and natural gas have positive and negative impacts on gross fixed capital formation, respectively. Employment, however, was found to have negative but insignificant impact on gross fixed capital formation. Moreover, the estimation results of demand side model suggest that natural gas price has negative and significant impact on natural gas consumption only in the long-run, though there is insignificant impact on economic growth. These results imply that the Iranian government's decision for natural gas price liberalization has the adverse effects on economic growth and policy makers should be cautious in doing this policy. - Highlights: • Iran has been considered as a major natural gas producer in the world. • This paper examines the relationship between gas consumption and growth in Iran. • Positive impact of gas consumption on growth has been obtained. • The paper finds that gas consumption and income reinforce each other in Iran. • Natural gas price has also negative and significant impact on natural gas consumption in Iran

Ndubuisi, E.N.; Amanetu, M.C.

2003-01-01

This paper presents a general overview of the African gas market, gas development, distribution, and utilization in Africa with particular emphasis on investment opportunities in Nigeria. Africa's non-renewable energy sources include fossil fuel such as coal, oil and natural gas. These fuels can be used to generate electricity. Their abundance is required for economic development and their efficient exploitation results in expansion of markets and industrialization, both of which are essential for Africa's social and economic progress. Natural gas is a premium fuel in the industrial, commercial and domestic sectors because of its unique characteristics. In Nigeria, the gas market is relatively untapped in the domestic sector, but much progress has been made in the past decade to develop and use natural gas as an energy feedstock for the cement and fertilizer industries. Some major gas transmission systems have been developed along with export oriented projects. 5 refs., 3 figs

Examination of the relationship between project management critical success factors and project success of oil and gas drilling projects

Science.gov (United States)

Alagba, Tonye J.

Oil and gas drilling projects are the primary means by which oil companies recover large volumes of commercially available hydrocarbons from deep reservoirs. These types of projects are complex in nature, involving management of multiple stakeholder interfaces, multidisciplinary personnel, complex contractor relationships, and turbulent environmental and market conditions, necessitating the application of proven project management best practices and critical success factors (CSFs) to achieve success. Although there is some practitioner oriented literature on project management CSFs for drilling projects, none of these is based on empirical evidence, from research. In addition, the literature has reported alarming rates of oil and gas drilling project failure, which is attributable not to technical factors, but to failure of project management. The aim of this quantitative correlational study therefore, was to discover an empirically verified list of project management CSFs, which consistent application leads to successful implementation of oil and gas drilling projects. The study collected survey data online, from a random sample of 127 oil and gas drilling personnel who were members of LinkedIn's online community "Drilling Supervisors, Managers, and Engineers". The results of the study indicated that 10 project management factors are individually related to project success of oil and gas drilling projects. These 10 CSFs are namely; Project mission, Top management support, Project schedule/plan, Client consultation, Personnel, Technical tasks, Client acceptance, Monitoring and feedback, Communication, and Troubleshooting. In addition, the study found that the relationships between the 10 CSFs and drilling project success is unaffected by participant and project demographics---role of project personnel, and project location. The significance of these findings are both practical, and theoretical. Practically, application of an empirically verified CSFs list to oil

The Norwegian Government stimulates the use of natural gas in this country at the same time as the increase in the energy consumption should be reduced as much as possible. Thus increased use of natural gas for energy purposes may lead to reduced consumption of other energy carriers, and the use of existing infrastructure must be taken into consideration. The introduction of natural gas increases the need for optimization of the energy consumption with respect to costs and environmental consequences. The principle aim of this project is to evaluate how to implement the increased use of natural gas into existing and planned energy systems in an optimal way.

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

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 supply-and-demand problems

Hatamian, H.

1998-01-01

World natural-gas consumption quadrupled in the 30 years from 1966 to 1996, and natural gas now provides 22% of the total world energy demand. The security of natural-gas supply is paramount and rests with the suppliers and the consumers. This paper gives an overview of world natural-gas supply and demand and examines the main supply problems. The most important nonpredictable variables in natural-gas supply are worldwide gas price and political stability, particularly in regions with high reserves. Other important considerations are the cost of development/processing and the transport of natural gas to market, which can be difficult to maintain if pipelines pass through areas of political instability. Another problem is that many countries lack the infrastructure and capital for effective development of their natural-gas industry. Unlike oil, the cost of transportation of natural gas is very high, and, surprisingly, only approximately 16% of the total world production currently is traded internationally

This presentation provided a customer's view of forward gas prices and outlined different buying behaviours in terms of characteristics of novice and seasoned buyers. It presented a portfolio overview of natural gas and described the risks facing customers in terms of fixed prices and fixed volumes. An energy smart price plan considers floating gas prices instead of a fixed market price. An automobile manufacturer was presented as an example of a gas consumer that would prefer to manage internal costs of production rather than manage gas volatility. The importance of understanding the drivers of individual businesses was emphasized. Natural Resources Canada and the Office of Energy Efficiency offer financial incentives for manufacturers for energy retrofit feasibility studies that result in energy retrofit projects in lighting, heating, boiler replacement, chiller upgrades, and heat recovery. tabs., 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. Some administrative problems are also mentioned. 2 tabs., 1 fig

The natural gas industry and market prospects in Canada are reviewed from a producer's point of view. In the first eight months of 1993, $2.3 billion in new equity was raised for natural gas exploration and production, compared to $900 million in 1991 and $1.2 billion in 1992. The number of wells drilled in the western Canada basin is expected to reach 8,000-9,000 in 1993, up from 5,600 in 1992, and Canadian producers' share of the North American natural gas market will probably reach 20% in 1993, up from 13% in 1986. Potential and proved gas supply in North America is ca 750 trillion ft 3 , of which ca 30% is in Canada. Factors affecting gas producers in Canada are the deregulated nature of the market, low costs for finding gas (finding costs in the western Canada basin are the lowest of any basin in North America), and the coming into balance of gas supply and demand. The former gas surplus has been reduced by expanding markets and by low prices which reduced the incentive to find new reserves. This surplus is largely gone, and prices have started rising although they are still lower than the pre-deregulation prices. Progress is continuing toward an integrated North American gas market in which a number of market hubs allow easy gas trading between producers and consumers. Commodity exchanges for hedging gas prices are beginning operation and electronic trading of gas contracts and pipeline capacity will also become a reality. 4 figs

The Brazilian Government, through the Program of massification of the use of the natural gas (NG), it tries to motivate the increase of the participation of this fuel in the national energy head office, stimulating his/her use in the most several sections. In the specific case of the Northeast, where thankfully problems of offer of this energy one exist, the discussion fits if the current proposal of the construction of costly gas pipelines should be implemented or she should use alternative forms to supply the demand for NG of the area (virtual gas pipelines: LNG or CNG). These technologies can induce the use in mass of NG, allowing not only the use of this energy nobleman for great consumers, as well as for the small ones, stimulating the increase of the energy efficiency. This article has as objective to do a reflection on the Northeastern market of NG and the forms of provisioning, using LNG, of areas now no assisted by the mesh of gas pipelines and that you/they are potential consuming. Before that solution alternatives will be discussed for a crucial subject in the expansion of the market of NG: the need of the construction of gas pipelines to supply markets no formed. Corroborating, like this, with the Plan of massification of the use of NG, generating alternative subsidies for the projects of expansion of markets of the energy. (author)

Roadmap for Development of Natural Gas Vehicle Fueling Infrastructructure and Analysis of Vehicular Natural Gas Consumption by Niche Sector

Energy Technology Data Exchange (ETDEWEB)

Stephen C. Yborra

2007-04-30

Vehicular natural gas consumption is on the rise, totaling nearly 200 million GGEs in 2005, despite declines in total NGV inventory in recent years. This may be attributed to greater deployment of higher fuel use medium- and heavy-duty NGVs as compared to the low fuel use of the natural gas-powered LDVs that exited the market through attrition, many of which were bi-fuel. Natural gas station counts are down to about 1100 from their peak of about 1300. Many of the stations that closed were under-utilized or not used at all while most new stations were developed with greater attention to critical business fundamentals such as site selection, projected customer counts, peak and off-peak fueling capacity needs and total station throughput. Essentially, the nation's NGV fueling infrastructure has been--and will continue--going through a 'market correction'. While current economic fundamentals have shortened payback and improved life-cycle savings for investment in NGVs and fueling infrastructure, a combination of grants and other financial incentives will still be needed to overcome general fleet market inertia to maintain status quo. Also imperative to the market's adoption of NGVs and other alternative fueled vehicle and fueling technologies is a clear statement of long-term federal government commitment to diversifying our nation's transportation fuel use portfolio and, more specifically, the role of natural gas in that policy. Based on the current NGV market there, and the continued promulgation of clean air and transportation policies, the Western Region is--and will continue to be--the dominant region for vehicular natural gas use and growth. In other regions, especially the Northeast, Mid-Atlantic states and Texas, increased awareness and attention to air quality and energy security concerns by the public and - more important, elected officials--are spurring policies and programs that facilitate deployment of NGVs and fueling

Analyzing Drivers of Conflict in Energy Infrastructure Projects: Empirical Case Study of Natural Gas Pipeline Sectors

Directory of Open Access Journals (Sweden)

Chan Young Park

2017-11-01

Full Text Available Energy infrastructure projects have caused various conflicts between stakeholders, particularly among the residents around construction sites and operators. The conflicts are largely due to the “Not in My Backyard” mentality associated with hazardous projects. In natural gas pipeline (NGP projects, conflicts have been increasing with the increase in a wider range of linear projects, and they have been worsening because of the lack of clear countermeasures. This study proposes an effective conflict management strategy for NGP projects in Korea. To achieve the objectives, 25 conflict drivers were identified and 143 case-based surveys were conducted to determine the causal relationship between the drivers and the level of conflict using structural equation modeling (SEM. The SEM results show that factors such as economic (e.g., decreased value of the land, construction-related (e.g., disturbance due to using the original route and site, and safety-related characteristics (e.g., concerns about explosions and accidents are the most important in understanding the causes of conflicts. Based on the causal relationship, five key strategies were proposed to manage the critical conflicts. This study can serve as a basis for implementing better conflict management plans in the future for a more sustainable project execution.

As natural gas is about to become the first energy source in the world, is abundant and easy to transport, this collective publication addresses issues related to shale gas and to natural gas. The first part addresses shale gas. Four articles propose a global overview, comment the situation in the USA which, in eight years of time, reduced their oil dependency by half and became almost self-sufficient as far as gas is concerned, discuss technical and legal issues related to shale gas exploitation, discuss the perspective of evolution of the world gas markets, and notice that shale gas will not be a game changer in Europe. The second part addresses the natural gas. The articles discuss the possible influence of natural gas exploitation by Israel on the Middle-East geopolitical situation, the influence of the emergence of new producers in Africa (Tanzania and Mozambique), the contribution of gas-fuelled power station to the coverage of market risks, and the issue of European energy safety with a focus on the role of Turkey

Gas hydrates are nonstoichiometric crystalline compounds that belong to the inclusion group known as clathrates. They occur when water molecules attach themselves together through hydrogen bonding and form cavities which can be occupied by a single gas or volatile liquid molecule. Gas hydrates, asphaltenes and waxes are three major threats to flow assurance that must be well assessed by design team uptime. Gas hydrates are also looked upon as a future energy source and as a potential climate hazard. The purpose of this review is to show the chemistry and mechanism of gas hydrate formation, the problems they pose, especially to flow assurance, their system implications, their environmental and economic perspectives with respect to their prospects as storage and transport alternative to the liquefied natural gas technology.

About 50% of the so-called 'greenhouse-effect' is not caused by CO 2 , but by more dangerous gases, among them is methane. Natural gas consists to about 98% of methane. In Austria result about 15% of the methane emissions from offtake, storage, transport (pipelines) and distribution from natural gas. A research study of the Research Centre Seibersdorf points out that between 2.5% and 3.6% of the employed natural gas in Austria emits. The impact of this emitted methane is about 29 times worse than the impact of CO 2 (caused for examples by petroleum burning). Nevertheless the Austrian CO 2 -commission states that an increasing use of natural gas would decrease the CO 2 -emissions - but this statement is suspected to be based on wrong assumptions.

The technologies and practices that have enabled the recent boom in shale gas production have also brought attention to the environmental impacts of its use. It has been debated whether the fugitive methane emissions during natural gas production and transmission outweigh the lower carbon dioxide emissions during combustion when compared to coal and petroleum. Using the current state of knowledge of methane emissions from shale gas, conventional natural gas, coal, and petroleum, we estimated up-to-date life-cycle greenhouse gas emissions. In addition, we developed distribution functions for key parameters in each pathway to examine uncertainty and identify data gaps such as methane emissions from shale gas well completions and conventional natural gas liquid unloadings that need to be further addressed. Our base case results show that shale gas life-cycle emissions are 6% lower than conventional natural gas, 23% lower than gasoline, and 33% lower than coal. However, the range in values for shale and conventional gas overlap, so there is a statistical uncertainty whether shale gas emissions are indeed lower than conventional gas. Moreover, this life-cycle analysis, among other work in this area, provides insight on critical stages that the natural gas industry and government agencies can work together on to reduce the greenhouse gas footprint of natural gas.

The objective of the proposed project was to confirm the feasibility of using blends of hydrogen and natural gas to improve the performance, efficiency, controllability and emissions of a homogeneous charge compression ignition (HCCI) engine. The project team utilized both engine simulation and laboratory testing to evaluate and optimize how blends of hydrogen and natural gas fuel might improve control of HCCI combustion. GTI utilized a state-of-the art single-cylinder engine test platform for the experimental work in the project. The testing was designed to evaluate the feasibility of extending the limits of HCCI engine performance (i.e., stable combustion, high efficiency and low emissions) on natural gas by using blends of natural gas and hydrogen. Early in the project Ricardo provided technical support to GTI as we applied their engine performance simulation program, WAVE, to our HCCI research engine. Modeling support was later provided by Digital Engines, LLC to use their proprietary model to predict peak pressures and temperatures for varying operating parameters included in the Design of Experiments test plan. Digital Engines also provided testing support for the hydrogen and natural gas blends. Prof. David Foster of University of Wisconsin-Madison participated early in the project by providing technical guidance on HCCI engine test plans and modeling requirements. The main purpose of the testing was to quantify the effects of hydrogen addition to natural gas HCCI. Directly comparing straight natural gas with the hydrogen enhanced test points is difficult due to the complexity of HCCI combustion. With the same air flow rate and lambda, the hydrogen enriched fuel mass flow rate is lower than the straight natural gas mass flow rate. However, the energy flow rate is higher for the hydrogen enriched fuel due to hydrogen’s significantly greater lower heating value, 120 mJ/kg for hydrogen compared to 45 mJ/kg for natural gas. With these caveats in mind, an

Some risks related to the short-term trading of natural gas

International Nuclear Information System (INIS)

Mazighi, Ahmed El Hachemi

2004-01-01

Traditionally guided by long-term contracts, the international natural gas trade is experiencing new methods of operating, based on the short term and more flexibility. Today, indeed, the existence of uncommitted quantities of natural gas, combined with gas price discrepancies among different regions of the world, gives room for the expansion of the spot-trading of gas. The main objective of this paper is to discuss three fundamental risks related to the short-term trading of natural gas: volume risk, price risk and infrastructure risk. The defenders of globalisation argue that the transition from the long-term to the short-term trading of natural gas is mainly a question of access to gas reserves, decreasing costs of gas liquefaction, the building of liquefied natural gas (LNG) fleets and regasification facilities and third-party access to the infrastructure. This process needs to be as short as possible, so that the risks related to the transition process will disappear rapidly. On the other hand, the detractors of globalisation put the emphasis on the complexity of the gas value chain and on the fact that eliminating long-term contracts increases the risks inherent to the international natural gas business. In this paper, we try to untangle and assess the risks related to the short-term trading of natural gas. Our main conclusions are: the short-term trading of gas is far from riskless; volume risk requires stock-building in both consuming and producing countries; price risk, through the high volatility for gas, induces an increase in options prices; there is no evidence to suggest that money-lenders' appetite for financing gas infrastructure projects will continue in a short-term trading system. This would be a threat to consumers' security of supply. (Author)

Globalization of the Natural Gas Industry

This document deals with the foreseeable evolution of natural gas demand in the next 15 years. Natural gas consumption is growing faster than any other fossil fuel and, according to ENRON, the natural consumption growth will continue. The environmental aspect of natural gas use for power generation is presented, showing that gas use reduces pollution emissions (when compared with coal). On top of that, it appears that the conversion efficiency of gas is much higher than the conversion efficiency of coal steam. Eventually, natural gas resources should meet energy demand for decades.

Determination and maintenance of DE minimis risk for migration of residual tritium (3H) from the 1969 Project Rulison nuclear test to nearby hydraulically fractured natural gas wells.

2013-05-01

The Project Rulison underground nuclear test was a proof-of-concept experiment that was conducted under the Plowshare Program in 1969 in the Williams Fork Formation of the Piceance Basin in west-central Colorado. Today, commercial production of natural gas is possible from low permeability, natural gas bearing formations like that of the Williams Fork Formation using modern hydraulic fracturing techniques. With natural gas exploration and production active in the Project Rulison area, this human health risk assessment was performed in order to add a human health perspective for site stewardship. Tritium (H) is the radionuclide of concern with respect to potential induced migration from the test cavity leading to subsequent exposure during gas-flaring activities. This analysis assumes gas flaring would occur for up to 30 d and produce atmospheric H activity concentrations either as low as 2.2 × 10 Bq m (6 × 10 pCi m) from the minimum detectable activity concentration in produced water or as high as 20.7 Bq m (560 pCi m), which equals the highest atmospheric measurement reported during gas-flaring operations conducted at the time of Project Rulison. The lifetime morbidity (fatal and nonfatal) cancer risks calculated for adults (residents and workers) and children (residents) from inhalation and dermal exposures to such activity concentrations are all below 1 × 10 and considered de minimis. The implications for monitoring production water for conforming health-protective, risk-based action levels also are examined.

Canadian natural gas winter 2005-06 outlook

International Nuclear Information System (INIS)

2005-11-01

An outline of the Canadian natural gas commodity market was presented along with an outlook for Canadian natural gas supply and prices for the winter heating season of 2005-2006. In Canada, the level of natural gas production is much higher than domestic consumption. In 2004, Canadian natural gas production was 16.9 billion cubic feet per day (Bcf/d), while domestic consumption was much lower at 8.2 Bcf/d. The United States, whose natural gas consumption is higher than production, imported about 16 per cent of its natural gas supply from Canada and 3 per cent from other countries via liquefied natural gas imports. Canadian natural gas exports to the United States in 2004 was 8.7 Bcf/d, representing 51 per cent of Canada's production. In Canada, the most important natural gas commodity markets that determine natural gas commodity prices include the intra-Alberta market and the market at the Dawn, Ontario natural gas hub. A well connected pipeline infrastructure connects the natural gas commodity markets in Canada and the United States, allowing supply and demand fundamentals to be transferred across all markets. As such, the integrated natural gas markets in both countries influence the demand, supply and price of natural gas. Canadian natural gas production doubled from 7 to 16.6 Bcf/d between 1986 and 2001. However, in the past 3 years, production from western Canada has leveled out despite record high drilling activity. This can be attributed to declining conventional reserves and the need to find new natural gas in smaller and lower-quality reservoirs. The combination of steady demand growth with slow supply growth has resulted in high natural gas prices since the beginning of 2004. In particular, hurricane damage in August 2005 disrupted natural gas production in the Gulf of Mexico's offshore producing region, shutting-in nearly 9 Bcf/d at the height of damage. This paper summarized some of the key factors that influence natural gas market and prices, with

The regulation of Natural Gas. Natural gas Regulation clarifies and consolidates the legal and institutional framework for development of the industry through six principal elements: 1) Establishment of a vision of the industry. 2) Development of regulatory objectives. 3) Determination of relationships among industry participants. 4) Clear specification of the role of PEMEX in the industry. 5) Definition of the functions of the Regulatory authority. 6) Creation of a transition regime. In parallel with the development of the substantive legal framework, the law of the Comision Reguladora de Energia (CRE) was also enacted by Congress in October 1995 to strength the institutional framework and implement the legal changes. This law defines the CRE as an agency of the Energy Ministry with technical, operational, and budgetary autonomy, and responsibility for implementing natural gas industry regulation. (Author)

Natural gas: redistributing the economic surplus

International Nuclear Information System (INIS)

Oliveira, A. de; Pinto Junior, H.Q.

1990-01-01

The natural gas has a limited role in the Brazilian energy balance. This role in industrial countries and some developing countries is much more important. Historically this contrasting situation can be explained by the limited natural gas reserves Brazil used to have. Since the oil crisis however the Brazilian natural gas reserves increased substantially without a similar increase in the role of natural gas in the energy balance. The existing institutional arrangement generates a struggle for the economic rent generated by natural gas production and consumption that seems to be at the core of this question. Our paper estimates the economic rent generated by natural gas in Brazil and its distribution among producers and consumers: it points toward a new institutional arrangement that could arguably, generate a new role for the natural gas in the Brazilian energy balance.

Government policy and access to natural gas service in Canada

Plourde, A.; Ryan, D.L.

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 Year 2014 and Short-Term Outlook First Estimates

Hureau, Geoffroy; Lecarpentier, Armelle

2015-01-01

CEDIGAZ first estimates confirm the slowdown in the growth of gas supply seen in the past two years. CEDIGAZ expects a moderate 1.1% growth, on a par with the previous year. Net slowdown in China's gas demand growth (+ 8% in 2014, versus 16%/y over 2008-13). European natural gas consumption decline worsened (- 10%), largely due to mild weather. Strong decline in CIS' gas production and consumption amidst the Ukraine conflict. Surging US production (+ 5.7%), driven by shale gas. Significant decline in international pipeline trade (- 4.8%): Russian gas exports at the lowest in decade: -13% (- 9.7% to Europe, - 24% to the CIS); US net pipeline imports down 5% (effect of shale gas). 2014 showed a turnaround on the LNG market, after four years of market tightening: Additional LNG supply in Asia, combined with weather-related weak demand. Dramatic reduction of both European and Asian spot LNG prices in this context. Positive developments of US LNG projects (Cameron, Cove Point, Freeport all took FID...), which will likely delay other competing LNG projects (Russia, Canada, East Africa). In the short term, global gas demand growth is likely to remain moderate. The European market will continue to suffer from strong competition with coal and renewables + slowdown in Chinese gas demand growth. Uncertainties on the future evolution of the well-supplied LNG market and international prices until 2020 (demand in price-sensitive emerging markets...). Increasing pressure to cut subsidies in emerging markets in order to increase supply for a more viable development of natural gas in the long term. Recent structural and not temporary factors which could affect long term gas demand growth, such as the competition with other energy fuels (coal). Energy policies and general environmental regulations will thus be critical factors influencing natural gas demand (China). The Asian market will keep a major influence on the global LNG market

Natural gas and crude oil

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

Natural gas in the transportation sector

Energy Technology Data Exchange (ETDEWEB)

Ask, T Oe; Einang, P M; Stenersen, D [MARINTEK (Norway)

1996-12-01

The transportation sector is responsible for more than 50% of all oil products consumed, and it is the fastest growing oil demand sector and the fastest growing source of emissions. During the last 10 years there have been a considerable and growing effort in developing internal combustion gas engines. This effort has resulted in gas engines with efficiencies comparable to the diesel engines and with emissions considerably lower than engines burning conventional fuels. This development offers us opportunities to use natural gas very efficiently also in the transportation sector, resulting in reduced emissions. However, to utilize all the built in abilities natural gas has as engine fuel, the natural gas composition must be kept within relatively narrow limits. This is the case with both diesel and gasoline today. A further development require therefore specified natural gas compositions, and the direct use of pipeline natural gas as today would only in limited areas be acceptable. An interesting possibility for producing a specified natural gas composition is by LNG (Liquid Natural Gas) production. (EG)

Egging, Ruud; Holz, Franziska; Gabriel, Steven A.

2010-01-01

We provide the description, mathematical formulation and illustrative results of the World Gas Model, a multi-period complementarity model for the global natural gas market with explicit consideration of market power in the upstream market. Market players include producers, traders, pipeline and storage operators, LNG (liquefied natural gas) liquefiers and regasifiers as well as marketers. The model data set contains more than 80 countries and regions and covers 98% of world wide natural gas production and consumption. We also include a detailed representation of cross-border natural gas pipelines and constraints imposed by long-term contracts in the LNG market. The model is calibrated to match production and consumption projections from the PRIMES [EC. European energy and transport: trends to 2030-update 2007. Brussels: European Commission; 2008] and POLES models [EC. World energy technology outlook - 2050 (WETO-H2). Brussels: European Commission; 2006] up to 2030. The results of our numerical simulations illustrate how the supply shares of pipeline and LNG in various regions in the world develop very differently over time. LNG will continue to play a major role in the Asian market, also for new importers like China and India. Europe will expand its pipeline import capacities benefiting from its relative proximity to major gas suppliers. (author)

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

Energy Technology Data Exchange (ETDEWEB)

Anon.

2000-06-01

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.

Crude oil and natural gas supplies and demands for Denmark

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

1995-01-01

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

Natural gas for vehicles

1996-01-01

This article presents compressed natural gas for vehicles (CNG), which can provide considerable advantages both as an alternative fuel and as a clean fuel. These assets are not only economic but also technical. The first part deals with what is at stake in developing natural gas as a motor fuel. The first countries to use CNG were those with natural gas resources in their subsoil. Today, with a large number of countries having to cope with growing concern about increasing urban pollution, natural gas is also seen as a clean fuel that can help cut vehicle pollutant emissions dramatically. In the second part a brief technical descriptions is given of CNG stations and vehicles, with the aim of acquainting the reader with some of CNG's specific technical features as compared to gasoline and diesel oil. Here CNG technologies are seen to be very close to the more conventional ones. (author)

NATURAL GAS RESOURCES IN DEEP SEDIMENTARY BASINS

From a geological perspective, deep natural gas resources are generally defined as resources occurring in reservoirs at or below 15,000 feet, whereas ultra-deep gas occurs below 25,000 feet. From an operational point of view, ''deep'' is often thought of in a relative sense based on the geologic and engineering knowledge of gas (and oil) resources in a particular area. Deep gas can be found in either conventionally-trapped or unconventional basin-center accumulations that are essentially large single fields having spatial dimensions often exceeding those of conventional fields. Exploration for deep conventional and unconventional basin-center natural gas resources deserves special attention because these resources are widespread and occur in diverse geologic environments. In 1995, the U.S. Geological Survey estimated that 939 TCF of technically recoverable natural gas remained to be discovered or was part of reserve appreciation from known fields in the onshore areas and State waters of the United. Of this USGS resource, nearly 114 trillion cubic feet (Tcf) of technically-recoverable gas remains to be discovered from deep sedimentary basins. Worldwide estimates of deep gas are also high. The U.S. Geological Survey World Petroleum Assessment 2000 Project recently estimated a world mean undiscovered conventional gas resource outside the U.S. of 844 Tcf below 4.5 km (about 15,000 feet). Less is known about the origins of deep gas than about the origins of gas at shallower depths because fewer wells have been drilled into the deeper portions of many basins. Some of the many factors contributing to the origin of deep gas include the thermal stability of methane, the role of water and non-hydrocarbon gases in natural gas generation, porosity loss with increasing thermal maturity, the kinetics of deep gas generation, thermal cracking of oil to gas, and source rock potential based on thermal maturity and kerogen type.

China's Growing Natural Gas Insecurity and the Potential of Chinese Shale Gas

International Nuclear Information System (INIS)

Seaman, John

2013-04-01

China is poised for a dramatic increase in its demand for natural gas. As total energy demand has risen to record levels in the last five years, China has found itself in an increasingly difficult bind: the social and environmental burden from coal is becoming too heavy to bear and a growing dependence on foreign oil is becoming strategically more risky with the passage of time. China's policy-makers and strategists continue to favor indigenous resources whenever possible, but projected increases in demand are so great and the cost of nuclear and renewable energy sources still so high that natural gas has become an increasingly natural choice. The country's gas demand is projected to double in the next three years, reaching 260 billion cubic meters per year (bcm/y) by 2015 as Beijing has set a target to increase the part of natural gas from 4% of China's energy mix today to more than 8% by the end of the 12. Five Year Plan (2011-2015). Further projections show that Chinese gas demand could reach 400 bcm/y in 2020 and 550 bcm/y or more in 2030. While this growing demand for gas will help China achieve its goals of reducing the carbon intensity of its GDP and cut much of the pollution from coal, it is also leading China further down a path it has long hoped to avoid: greater dependence on strategic energy imports. A pipeline project to pump gas from Turkmenistan through Central Asia began delivering supplies in 2009 and is expected to reach 40 bcm/y in the near future and possibly even 65 bcm/y or more by 2020. Another pipeline from Myanmar is expected to enter into service in 2013 and would be capable of delivering up to 12 bcm/y. Negotiations with Russia for pipelines that could deliver anywhere from 30-70 bcm/y are deadlocked over pricing, but the construction of LNG import terminals suggests that China could be capable of importing between 40-50 bcm/y of this sea-borne gas by 2015 and possibly even 100 bcm/y or more by 2020.

2011-01-01

In this paper we consider the problem of natural gas consumption hourly forecast on the basis of hourly movement of temperature and natural gas consumption in the preceding period. There are various methods and approaches for solving this problem in the literature. Some mathematical models with linear and nonlinear model functions relating to natural gas consumption forecast with the past natural gas consumption data, temperature data and temperature forecast data are mentioned. The methods are tested on concrete examples referring to temperature and natural gas consumption for the area of the city of Osijek (Croatia) from the beginning of the year 2008. The results show that most acceptable forecast is provided by mathematical models in which natural gas consumption and temperature are related explicitly.

Since 1970, the portion of natural gas in energy consumption in Western-Europe has grown by 6 percent per year on the average. About 20 percent of the energy demand in Western-Europe is now covered by natural gas. It is forecasted that this growth will continue at a rate of 2 percent per year until 2010. The natural gas consumption will increase from 325 billion cubic metres in 1993 to 450 billion cubic metres per year in 2010. For the coming 10 to 15 years, the natural gas demand is covered by long-term contracts with gas producing countries. From 2010 on, additional contracts, covering 70 to 120 billion cubic metres per year are required. A shift in geographic distribution of countries from which natural gas will be imported by Western-European countries is expected, which implies high investments and additional costs for transport and distribution of natural gas. Due to its qualities with respect to environmental impact, yield, availability, and advanced technology, natural gas is the energy vector of the 21 first century. (A.S.)

Energy forecasting requirements for Slovenia's natural gas market were investigated along with the cycles of natural gas consumption. This paper presented a short-term natural gas forecasting approach where the daily, weekly and yearly gas consumption were analyzed and the information obtained was incorporated into the forecasting model for hourly forecasting for the next day. The natural gas market depends on forecasting in order to optimize the leasing of storage capacities. As such, natural gas distribution companies have an economic incentive to accurately forecast their future gas consumption. The authors proposed a forecasting model with the following properties: two submodels for the winter and summer seasons; input variables including past consumption data, weather data, weather forecasts and basic cycle indexes; and, a hierarchical forecasting structure in which a daily model was used as the basis, with the hourly forecast obtained by modeling the relative daily profile. This proposed method was illustrated by a forecasting example for Slovenia's natural gas market. 11 refs., 11 figs

The experts of energy policy agree to predict a brilliant future for natural gas. Among fossil energies, natural gas produces the least quantity of CO 2 . Geological reserves are estimated to 65 years for gas and 43 years for petroleum. Throughout the world, industrial infrastructures of gas production, transport and distribution are being developed, for instance 430000 km of gas pipeline are planned. In western Europe half the increase of gas demand by 2010 will be due to electricity production. Innovative techniques using natural gas are studied in various fields: cogeneration, transport, urban heating and fuel cells. The gas-fed fuel cell is based on a reversed electrolysis: hydrogen produced by the decomposition of natural gas interacts with oxygen and yields electricity. (A.C.)

The Adsorbed Natural Gas (ANG) storage technology is reviewed. The present status, theoretical limits and operational problems are discussed. Natural gas (NG) has a considerable advantage over conventional fuels both from an environmental point of view and for its natural abundance. However, as well known, it has a two fold disadvantage compared with liquid fuels: it is relatively expensive to transport from the remote areas, and its energy density (heat of combustion/volume) is low. All these will restrict its use. Compressed natural gas (CNG) may be a solution, but high pressures are needed (up to 25 MPa) for use in natural-gas fueled vehicles, and the large cost of the cylinders for storage and the high-pressure facilities necessary limit the practical use of CNG. Alternatively, adsorbed natural gas (ANG) at 3 - 4 MPa offers a very high potential for exploitation in both transport and large-scale applications. At present, research about this technology mainly focuses on: to make adsorbents with high methane adsorption capacity; to make clear the effects of heat of adsorption and the effect of impurities in natural gas on adsorption and desorption capacity. This paper provides an overview of current technology and examines the relations between fundamentals of adsorption and ANG storage. (authors)

Energy Security prospects in Cyprus and Israel: A focus on Natural Gas

Directory of Open Access Journals (Sweden)

Full Text Available The global production of natural gas has increased from 1226 bcm in 1973 to 3282 bcm in 2010 and is projected to continue rising by an annual growth rate of 1.6% between 2010 to 2035. Cyprus and Israel have recently made major offshore discoveries of natural gas, which can supply to a great extent the two countries’ current domestic energy needs for the next few decades and still export a substantial volume. MESSAGE, a global optimization model was used to explore the possible interactions between the two countries’ energy systems. Scenarios are presented that assess the export potential for electricity (generated by gas-fired power plants, liquefied natural gas (LNG or gas-to-liquid products (GTL. The results are compared to a scenario without any available reserves to illustrate the financial benefits that will arise from the exploitation of the gas resources in the two countries.

Natural gas could be an important alternative energy source in meeting some of the market demand presently met by liquid products from crude oil. This study was initiated to analyze three energy markets to determine if greater use could be made of natural gas or natural gas derived products and if those products could be provided on an economically competitive basis. The three markets targeted for possible increases in gas use were motor fuels, power generation, and the chemical feedstocks market. The economics of processes to convert natural gas to transportation fuels, chemical products, and power were analyzed. The economic analysis was accomplished by drawing on a variety of detailed economic studies, updating them and bringing the results to a common basis. The processes analyzed included production of methanol, MTBE, higher alcohols, gasoline, CNG, and LNG for the transportation market. Production and use of methanol and ammonia in the chemical feedstock market and use of natural gas for power generation were also assessed. Use of both high and low quality gas as a process feed stream was evaluated. The analysis also explored the impact of various gas price growth rates and process facility locations, including remote gas areas. In assessing the transportation fuels market the analysis examined production and use of both conventional and new alternative motor fuels

Natural gas, which is a general term of flammable hydrocarbon gases such as methane, is classified by origin into the following categories : (1) oil field gas (oil gas), (2) aquifers (bacteria-fermented methane), (3) coal gas (coal field gas), and (4) abiogenetic gas. The natural gas which has (1-4) origins and is now used as resource in a large quantity is (1) oil field gas. This gas is a hydrocarbon gas recovered in the production process of petroleum and contains components such as ethane, propane and butane. To the contrary, (2) aquifers and (3) coal gas have methane as main component. As (4) abiogenetic methane, there are gas formed in inorganic reaction in activities of submarine volcanos and deep gas (earth origin gas). Oil field gas has kerogen origin. Aquifers were formed by fermentation of organic matters. Coal gas was formed by coalification of vitrinite. As abiogenetic methane, there are inorganic reaction formation gas and deep gas, the latter of which exists little as resource. 7 refs., 11 figs., 1 tab.

This paper investigates the basic stylised facts of natural gas price movements using data for the period that natural gas has been traded on an organised exchange and the methodology suggested by Kydland and Prescott (1990). Our results indicate that natural gas prices are procyclical and lag the cycle of industrial production. Moreover, natural gas prices are positively contemporaneously correlated with United States consumer prices and lead the cycle of consumer prices, raising the possibility that natural gas prices might be a useful guide for US monetary policy, like crude oil prices are, possibly serving as an important indicator variable.

This study endeavours to determine whether farmers adjust their consumption of natural gas and liquefied petroleum gas in response to changes in the unit price of energy. A demand model is specified and estimated. The conclusions suggest that the unit price of natural gas (liquefied petroleum gas) is a factor impacting the quantity of natural gas (liquefied petroleum gas) demanded by farmers, but there is no indication that other types of energy are substitutes for natural gas or liquefied petroleum gas. Additionally, the number of acres irrigated is an important factor driving the demand for natural gas and liquefied petroleum gas. Finally, the estimated models of natural gas and liquefied petroleum gas demand were structurally stable over the period 1971-1989. (author)

Natural gas is currently transported by two main ways: through pipelines and stored in reservoirs, under compressed (CNG) or liquefied (LNG) forms. Adsorbed natural gas (ANG) is a third alternative to vessel storage, which has been intensively reported in the scientific and technical literature. Working pressures are considerably lower for ANG (3,5 MPa as compared to 25 MPa for CNG), which results in lower costs with vessel construction and compression and safer handling. The project ADSPOR, sponsored by PETROBRAS and part of the R and D portfolio of RedeGasEnergia, aims to assess the technical and economical feasibility of storing and transporting natural gas confined in carbon adsorbents. The objectives of this project are the production of high-capacity active carbons, the collection of adsorption data for NG storage and the economic evaluation of ANG. The present work presents a model for cost estimation of the ANG business, which comprises from the compression into ANG vessels until the distribution to the final costumer, taking into account several shipping modes. The variables involved in the model were: compression costs, equipment and materials technical data, costs with product handling and shipping costs for motor ways, railways and inland waterways. These variables were linked so as to generate a cost matrix that may be used to assess investment and calculate the final cost for GNA transport. The model may be used to carry out parameter sensitivity analysis, for decision-making and management purposes. (author)

Greenhouse gas emissions from high demand, natural gas-intensive energy scenarios

International Nuclear Information System (INIS)

Victor, D.G.

1990-01-01

Since coal and oil emit 70% and 30% more CO 2 per unit of energy than natural gas (methane), fuel switching to natural gas is an obvious pathway to lower CO 2 emissions and reduced theorized greenhouse warming. However, methane is, itself, a strong greenhouse gas so the CO 2 advantages of natural gas may be offset by leaks in the natural gas recovery and supply system. Simple models of atmospheric CO 2 and methane are used to test this hypothesis for several natural gas-intensive energy scenarios, including the work of Ausubel et al (1988). It is found that the methane leaks are significant and may increase the total 'greenhouse effect' from natural gas-intensive energy scenarios by 10%. Furthermore, because methane is short-lived in the atmosphere, leaking methane from natural gas-intensive, high energy growth scenarios effectively recharges the concentration of atmospheric methane continuously. For such scenarios, the problem of methane leaks is even more serious. A second objective is to explore some high demand scenarios that describe the role of methane leaks in the greenhouse tradeoff between gas and coal as energy sources. It is found that the uncertainty in the methane leaks from the natural gas system are large enough to consume the CO 2 advantages from using natural gas instead of coal for 20% of the market share.

Natural gas vehicles. An option for Europe

International Nuclear Information System (INIS)

Engerer, Hella; Horn, Manfred

In Europe natural gas vehicles play a minor role. A decisive reason for this is the dependence of most European countries from gas imports. Except for Italy, there is no tradition to use natural gas as fuel. In addition, there is a lack of infrastructure (e.g. fuelling stations). In contrast to Europe, in Latin American and Asian countries natural gas vehicles are widespread. Some countries foster natural gas vehicles because they have own gas resources. Many countries must reduce the high air pollution in big cities. Environmental reasons are the main motive for the use of natural gas vehicles in Europe. In last years, high oil prices stimulated the use of natural gas as fuel. European governments have developed incentives (e.g. tax reductions) to foster natural gas vehicles. However, the focus is on hybrid technology and the electric car, which, however, need further technical improvement. In contrast, the use of natural gas in conventional engines is technically mature. Additional gas imports can be avoided by further improvements of energy efficiency and the use of renewable energy. In sum, the market penetration of natural gas as fuel should be promoted in Europe.
