Coccia, G.

1993-01-01

With reference to the 1992 CEDIGAZ (Centre International sur le Gas Naturel et tous Hydrocarbures Gazeux) report on world natural gas supply and demand, this paper assesses current market and production trends in this industry. The slight drop in production in 1992, the first which has which has occurred after many consecutive years of steady increases, is ascribed to ownership disputes among the former-USSR republics and major changes in the organizational structure of the former-USSR's natural gas industry. Strong increases in demand are forecasted due to expected strong population growth and increased industrialization to take place in China and India. Price trends in natural gas should remain steady as a result of plentiful supplies of this fuel and coal, a major competitor. The use of relatively clean natural gas is suggested as a practical alternative to energy taxes now being proposed as a means for the reduction of greenhouse gas emissions

Natural gas: reserves keep ahead of production

Energy Technology Data Exchange (ETDEWEB)

Hough, G V

1983-08-01

World production of natural gas in 1982 fell only 1.6% below 1981 levels, while proven recoverable reserves were up by 3.6% for a total of 3.279 quadrillion CF, which is 32.4% higher than had been estimated in 1978. Gas consumption, however, has experienced greater changes, with most of the industrialized countries (except for Japan) reporting declines in gas demand resulting from falling oil prices, reduced energy demand, and a slack world economy. Although gas seems to be holding its own in energy markets, further progress will not be easy to achieve.

Natural gas is a clean burning alternative to other fossil fuels, producing lower carbon dioxide (CO2) emissions during combustion. Gas deposits located within shale rock or tight sand formations are difficult to access using conventional drilling techniques. However, horizontal drilling coupled with hydraulic fracturing is now widely used to enhance natural gas extraction. Potential environmental impacts of these practices are currently being assessed because of the rapid expansion of natural gas production in the U.S. Natural gas production has contributed to the deterioration of air quality in several regions, such as in Wyoming and Utah, that were near or downwind of natural gas basins. We conducted a field campaign in southwestern Pennsylvania on 16-18 June 2012 to investigate the impact of gas production operations in the Marcellus Shale on regional air quality. A total of 235 whole air samples were collected in 2-liter electropolished stainless- steel canisters throughout southwestern Pennsylvania in a regular grid pattern that covered an area of approximately 8500 square km. Day and night samples were collected at each grid point and additional samples were collected near active wells, flaring wells, fluid retention reservoirs, transmission pipelines, and a processing plant to assess the influence of different stages of the gas production operation on emissions. The samples were analyzed at Appalachian State University for methane (CH4), CO2, C2-C10 nonmethane hydrocarbons (NMHCs), C1-C2 halocarbons, C1-C5 alkyl nitrates and selected reduced sulfur compounds. In-situ measurements of ozone (O3), CH4, CO2, nitric oxide (NO), total reactive nitrogen (NOy), formaldehyde (HCHO), and a range of volatile organic compounds (VOCs) were carried out at an upwind site and a site near active gas wells using a mobile lab. Emissions associated with gas production were observed throughout the study region. Elevated mixing ratios of CH4 and CO2 were observed in the

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.

1998-01-01

The steam and gas turbine power plant for combine heat (for district heating of Skopje - the capital of Macedonia) and power (connected to the grid) production is analyzed and determined. Two variants of power plants are analyzed: power plant with gas turbine, heat recovery steam generator and a back pressure steam turbine; and power plant with two gas turbines, two heat recovery steam generators (HRSG) and one back pressure steam turbine. The power plant would operate on natural gas as the main fuel source. It will be burnt in the gas turbine as well in the HRSG as an auxiliary fuel.The backup fuel for the gas turbine would be light oil. In normal operation, the HRSG uses the waste heat of the exhaust gases from the gas turbine. During gas turbine shutdowns, the HRSG can continue to generate the maximum steam capacity. The heat for district heating would be produce in HRSG by flue gases from the gas turbine and in the heat exchanger by condensed steam from back pressure turbine. The main parameters of the combined power plant, as: overall energy efficiency, natural gas consumption, natural gas saving are analyzed and determined in comparison with separated production of heat (for district heating) and power (for electrical grid).

In order to achieve energy consumption targets, and subsequently reduce carbon emissions, China is working on energy strategies and policies aimed at actively increasing the consumption of natural gas—the lowest carbon energy of the fossil fuels, and to enhance the proportion of gas in total primary energy consumption. To do this, it is a necessary prerequisite that China must have access to adequate gas resources and production to meet demand. This paper shows that the availability of domestic gas resources are overestimated by China's authorities due to differences in classification and definitions of gas resources/reserves between China and those accepted internationally. Based on official gas resource figures, China's gas production remains low with respect to the projected demand, and will only be 164.6 bcm in 2020, far lower than the 375 bcm of forecast demand. The gap between gas production and demand will reach 210.4 bcm by 2020. Existing plans for the importation of gas and the development of unconventional gas will not close this gap in the next 10 years, and this situation will therefore present a severe challenge to China's gas security, achievement of targets in improving energy consumption structure and reducing carbon emissions. - Highlights: ► We show that available gas resources are overestimated by China's authorities. ► We forecast China's future gas production under different resource scenarios. ► This paper shows that China's gas production will not meet the soaring demand. ► The gap between supply and demand will continue to increase rapidly in future. ► China's gas security will meet a severe challenge because of this increasing gap

Microbial production of natural gas from coal and organic-rich shale

Natural gas is an important component of the energy mix in the United States, producing greater energy yield per unit weight and less pollution compared to coal and oil. Most of the world’s natural gas resource is thermogenic, produced in the geologic environment over time by high temperature and pressure within deposits of oil, coal, and shale. About 20 percent of the natural gas resource, however, is produced by microorganisms (microbes). Microbes potentially could be used to generate economic quantities of natural gas from otherwise unexploitable coal and shale deposits, from coal and shale from which natural gas has already been recovered, and from waste material such as coal slurry. Little is known, however, about the microbial production of natural gas from coal and shale.

Natural gas productive capacity for the lower 48 States, 1980 through 1995

International Nuclear Information System (INIS)

1994-01-01

The purpose of this report is to analyze monthly natural gas wellhead productive capacity in the lower 48 States from 1980 through 1992 and project this capacity from 1993 through 1995. For decades, natural gas supplies and productive capacity have been adequate to meet demand. In the 1970's the capacity surplus was small because of market structure (split between interstate and intrastate), increasing demand, and insufficient drilling. In the early 1980's, lower demand, together with increased drilling, led to a large surplus capacity as new productive capacity came on line. After 1986, this large surplus began to decline as demand for gas increased, gas prices fell, and gas well completions dropped sharply. In late December 1989, the decline in this surplus, accompanied by exceptionally high demand and temporary weather-related production losses, led to concerns about the adequacy of monthly productive capacity for natural gas. These concerns should have been moderated by the gas system's performance during the unusually severe winter weather in March 1993 and January 1994. The declining trend in wellhead productive capacity is expected to be reversed in 1994 if natural gas prices and drilling meet or exceed the base case assumption. This study indicates that in the low, base, and high drilling cases, monthly productive capacity should be able to meet normal production demands through 1995 in the lower 48 States (Figure ES1). Exceptionally high peak-day or peak-week production demand might not be met because of physical limitations such as pipeline capacity. Beyond 1995, as the capacity of currently producing wells declines, a sufficient number of wells and/or imports must be added each year in order to ensure an adequate gas supply

European energy security: The future of Norwegian natural gas production

Soederbergh, Bengt; Jakobsson, Kristofer; Aleklett, Kjell

2009-01-01

The European Union (EU) is expected to meet its future growing demand for natural gas by increased imports. In 2006, Norway had a 21% share of EU gas imports. The Norwegian government has communicated that Norwegian gas production will increase by 25-40% from today's level of about 99 billion cubic meters (bcm)/year. This article shows that only a 20-25% growth of Norwegian gas production is possible due to production from currently existing recoverable reserves and contingent resources. A high and a low production forecast for Norwegian gas production is presented. Norwegian gas production exported by pipeline peaks between 2015 and 2016, with minimum peak production in 2015 at 118 bcm/year and maximum peak production at 127 bcm/year in 2016. By 2030 the pipeline export levels are 94-78 bcm. Total Norwegian gas production peaks between 2015 and 2020, with peak production at 124-135 bcm/year. By 2030 the production is 96-115 bcm/year. The results show that there is a limited potential for increased gas exports from Norway to the EU and that Norwegian gas production is declining by 2030 in all scenarios. Annual Norwegian pipeline gas exports to the EU, by 2030, may even be 20 bcm lower than today's level.

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

How does increased corn-ethanol production affect US natural gas prices?

International Nuclear Information System (INIS)

Whistance, Jarrett; Thompson, Wyatt

2010-01-01

In recent years, there has been a push to increase biofuel production in the United States. The biofuel of choice, so far, has been ethanol produced from corn. The effects of increased corn-ethanol production on the consumer prices of food and energy continue to be studied and debated. This study examines, in particular, the effects of increased corn-ethanol production on US natural gas prices. A structural model of the natural gas market is developed and estimated using two stage least squares. A baseline projection for the period 2007-2018 is determined, and two scenarios are simulated. In the first scenario, current biofuel policies including EISA mandates, tariffs, and tax credits are removed. In the second scenario, we hold ethanol production to the level required only for largely obligatory additive use. The results indicate that the increased level of corn-ethanol production occurring as a result of the current US biofuel policies may lead to natural gas prices that are as much as 0.25% higher, on average, than if no biofuel policies were in place. A similar comparison between the baseline and second scenario indicates natural gas prices could be as much as 0.5% higher, on average, for the same period.

Environmental review of natural gas production in Lake Erie

International Nuclear Information System (INIS)

O'Shea, K.

2002-01-01

The water of Lake Erie is used as a source of drinking water for Ontario, New York, Pennsylvania, Ohio and Michigan. An environmental review has been conducted to determine the impact of drilling operations on the overall ecology of the lake. Since 1913, 2000 natural gas wells have been drilled in Lake Erie, of which 550 currently produce gas and account for 75 per cent of Ontario's total gas production. 180 wells are shut-in or suspended and the remaining wells have been abandoned. The gas wells are connected to onshore production facilities by approximately 1,600 km of small diameter pipelines that lie buried near shore or on top of the lake bed. Nearly 90 per cent of the in-lake infrastructure is in water depths of more than 20 metres. Talisman Energy is actively involved with the Canadian Coast Guard, the Department of Fisheries and Oceans, and the Ministry of Natural Resources to ensure cooperation between regulators and off-shore personnel. The environmental assessment of natural gas production in Lake Erie included a review of regulatory and best management practices, a biophysical overview of the lake, and a review of drilling practices, well completions, handling of waste streams, materials management, operations inspections, wastewater discharge, air emissions, and oil spills. It was revealed that for most drilling programs, cuttings are washed and discharged to the Lake. Ongoing testing will determine the impact that this practice has on benthic populations. The drill muds used for drilling operations are water based, environmentally friendly, and re-used between well locations. For completion programs, all well activities are closed circuit operations. Wells are abandoned through plugging with cement, removing wellheads and casing below the lake bottom. There has been a reported volume of about 23,000 litres of spilled product from 1990 to 2001, of which 68 per cent has come from 3 industrial companies that operate near Lake Erie. The offshore gas

Experience curve for natural gas production by hydraulic fracturing

2017-01-01

From 2007 to 2012 shale gas production in the US expanded at an astounding average growth rate of over 50%/yr, and thereby increased nearly tenfold over this short time period alone. Hydraulic fracturing technology, or “fracking”, as well as new directional drilling techniques, played key roles in this shale gas revolution, by allowing for extraction of natural gas from previously unviable shale resources. Although hydraulic fracturing technology had been around for decades, it only recently became commercially attractive for large-scale implementation. As the production of shale gas rapidly increased in the US over the past decade, the wellhead price of natural gas dropped substantially. In this paper we express the relationship between wellhead price and cumulative natural gas output in terms of an experience curve, and obtain a learning rate of 13% for the industry using hydraulic fracturing technology. This learning rate represents a measure for the know-how and skills accumulated thus far by the US shale gas industry. The use of experience curves for renewable energy options such as solar and wind power has allowed analysts, practitioners, and policy makers to assess potential price reductions, and underlying cost decreases, for these technologies in the future. The reasons for price reductions of hydraulic fracturing are fundamentally different from those behind renewable energy technologies – hence they cannot be directly compared – and hydraulic fracturing may soon reach, or maybe has already attained, a lower bound for further price reductions, for instance as a result of its water requirements or environmental footprint. Yet, understanding learning-by-doing phenomena as expressed by an industry-wide experience curve for shale gas production can be useful for strategic planning in the gas sector, as well as assist environmental policy design, and serve more broadly as input for projections of energy system developments. - Highlights: • Hydraulic

US production of natural gas from tight reservoirs

International Nuclear Information System (INIS)

1993-01-01

For the purposes of this report, tight gas reservoirs are defined as those that meet the Federal Energy Regulatory Commission's (FERC) definition of tight. They are generally characterized by an average reservoir rock permeability to gas of 0.1 millidarcy or less and, absent artificial stimulation of production, by production rates that do not exceed 5 barrels of oil per day and certain specified daily volumes of gas which increase with the depth of the reservoir. All of the statistics presented in this report pertain to wells that have been classified, from 1978 through 1991, as tight according to the FERC; i.e., they are ''legally tight'' reservoirs. Additional production from ''geologically tight'' reservoirs that have not been classified tight according to the FERC rules has been excluded. This category includes all producing wells drilled into legally designated tight gas reservoirs prior to 1978 and all producing wells drilled into physically tight gas reservoirs that have not been designated legally tight. Therefore, all gas production referenced herein is eligible for the Section 29 tax credit. Although the qualification period for the credit expired at the end of 1992, wells that were spudded (began to be drilled) between 1978 and May 1988, and from November 5, 1990, through year end 1992, are eligible for the tax credit for a subsequent period of 10 years. This report updates the EIA's tight gas production information through 1991 and considers further the history and effect on tight gas production of the Federal Government's regulatory and tax policy actions. It also provides some high points of the geologic background needed to understand the nature and location of low-permeability reservoirs

Constant rate natural gas production from a well in a hydrate reservoir

2003-01-01

Using a computational model, production of natural gas at a constant rate from a well that is drilled into a confined methane hydrate reservoir is studied. It is assumed that the pores in the reservoir are partially saturated with hydrate. A linearized model for an axisymmetric condition with a fixed well output is used in the analysis. For different reservoir temperatures and various well outputs, time evolutions of temperature and pressure profiles, as well as the gas flow rate in the hydrate zone and the gas region, are evaluated. The distance of the decomposition front from the well as a function of time is also computed. It is shown that to maintain a constant natural gas production rate, the well pressure must be decreased with time. A constant low production rate can be sustained for a long duration of time, but a high production rate demands unrealistically low pressure at the well after a relatively short production time. The simulation results show that the process of natural gas production in a hydrate reservoir is a sensitive function of reservoir temperature and hydrate zone permeability

Natural gas use in electricity generation in Texas was estimated, for gas prices ranging from $1.89 to $7.74 per MMBTU, using an optimal power flow model. Hourly estimates of electricity generation, for individual electricity generation units, from the model were used to estimate spatially resolved hourly emissions from electricity generation. Emissions from natural gas production activities in the Barnett Shale region were also estimated, with emissions scaled up or down to match demand in electricity generation as natural gas prices changed. As natural gas use increased, emissions decreased from electricity generation and increased from natural gas production. Overall, NOx and SO2 emissions decreased, while VOC emissions increased as natural gas use increased. To assess the effects of these changes in emissions on ozone and particulate matter concentrations, spatially and temporally resolved emissions were used in a month-long photochemical modeling episode. Over the month-long photochemical modeling episode, decreases in natural gas prices typical of those experienced from 2006 to 2012 led to net regional decreases in ozone (0.2-0.7 ppb) and fine particulate matter (PM) (0.1-0.7 μg/m(3)). Changes in PM were predominantly due to changes in regional PM sulfate formation. Changes in regional PM and ozone formation are primarily due to decreases in emissions from electricity generation. Increases in emissions from increased natural gas production were offset by decreasing emissions from electricity generation for all the scenarios considered.

Lightweight Approaches to Natural Gas Hydrate Exploration & Production

Max, M. D.; Johnson, A. H.

Lower-cost approaches to drilling and reservoir utilization are made possible by adapting both emerging and new technology to the unique, low risk NGH natural gas resource. We have focused on drilling, wellbore lining technology, and reservoir management with an emphasis on long-term sand control and adaptive mechanical stability during NGH conversion to its constituent gas and water. In addition, we suggest that there are opportunities for management of both the gas and water with respect to maintaining desired thermal conditions. Some of the unique aspects of NGH deposits allow for new, more efficient technology to be applied to development, particularly in drilling. While NGH-bearing sands are in deepwater, they are confined to depths beneath the seafloor of 1.2 kilometers or less. As a result, they will not be significantly above hydrostatic pressure, and temperatures will be less than 30 oC. Drilling will be through semi-consolidated sediment without liquid hydrocarbons. These characteristics mean that high capability drillships are not needed. What is needed is a new perspective about drilling and producing NGH. Drilling from the seafloor will resolve the high-pressure differential between a wellhead on the sea surface in a vessel and reservoir to about the hydrostatic pressure difference between the seafloor and, at most, the base of the GHSZ. Although NGH production will begin using "off-the-shelf" technology, innovation will lead to new technology that will bring down costs and increase efficiency in the same way that led to the shale breakthrough. Commercial success is possible if consideration is given to what is actually needed to produce NGH in a safe and environmentally manner. Max, M.D. 2017. Wellbore Lining for Natural Gas Hydrate.

A series of overhead viewgraphs accompanied this presentation which focused on various aspects of the natural gas industry in Mexico. Some of the viewgraphs depicted statistics from 1998 regarding natural gas throughput from various companies in North America, natural gas reserves around the world, and natural gas reserves in Mexico. Other viewgraphs depicted associated and non-associated natural gas production from 1988 to 1998 in million cubic feet per day. The Burgos Basin and the Cantarell Basin gas production from 1997 to 2004 was also depicted. Other viewgraphs were entitled: (1) gas processing infrastructure for 1999, (2) cryogenic plant at Cd. PEMEX, (3) average annual growth of dry natural gas production for 1997-2004 is estimated at 5.2 per cent, (4) gas flows for December 1998, (5) PGPB- interconnect points, (6) U.S. Mexico gas trade for 1994-1998, (7) PGPB's interconnect projects with U.S., and (8) natural gas storage areas. Technological innovations in the industry include more efficient gas turbines which allow for cogeneration, heat recovery steam generators which reduce pollutant emissions by 21 per cent, cold boxes which increase heat transfer efficiency, and lateral reboilers which reduce energy consumption and total costs. A pie chart depicting natural gas demand by sector shows that natural gas for power generation will increase from 16 per cent in 1997 to 31 per cent in 2004. The opportunities for cogeneration projects were also reviewed. The Comision Federal de Electricidad and independent power producers represent the largest opportunity. The 1997-2001 investment program proposes an 85 per cent sulphur dioxide emission reduction compared to 1997 levels. This presentation also noted that during the 1998-2001 period, total ethane production will grow by 58 tbd. 31 figs

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.

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

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

Prospects for Strengthening the Security of Ukraine’s Energy Supply through Development of Unconventional Natural Gas Production

Full Text Available The article presents an analysis of the American experience in development of natural shale gas in the US, identifies the causes that led to the shale revolution. Its current state is characterized by achieving the peak production simultaneously with shift in the emphasis from natural shale gas to shale oil. The potential technically extracted gas reserves as well as trends in terms of the growth of conventional natural gas reserves and the development of trade in liquefied natural gas are regarded as global preconditions for enlargement of the shale natural gas output. Natural shale gas can be considered as an alternative project only for liquefied natural gas while, compared to pipeline gas, its production is uncompetitive. The national preconditions for development of the industry of nonconventional natural gas production are determined on the basis of the current trends in Ukraine’s gas market. The main obstacles to the realization of this direction are reduction of the gas needs and liberalization of natural gas trade on the basis of European principles. Economic evaluation of the feasibility of natural shale gas production made it possible to forecast its production cost at the wellhead at different depths and estimate its investment attractiveness in different aggregate states. On the basis of the approbation of the presented methodological approach carried out for the Dnieper-Donets and Carpathian shale basins, it was concluded that the investment attractiveness of the first one is higher, given its reservoir properties and the presence of deposits of nonconventional hydrocarbons in different states of aggregation.

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.

Muradov, N. [Florida Solar Energy Center, Cocoa, FL (United States)

1996-10-01

The conventional methods of hydrogen production from natural gas (for example, steam reforming and partial oxidation) are complex, multi-step processes that produce large quantities of CO{sub 2}. The main goal of this project is to develop a technologically simple process for hydrogen production from natural gas (NG) and other hydrocarbon fuels via single-step decomposition of hydrocarbons. This approach eliminates or significantly reduces CO{sub 2} emission. Carbon is a valuable by-product of this process, whereas conventional methods of hydrogen production from NG produce no useful by-products. This approach is based on the use of special catalysts that reduce the maximum temperature of the process from 1400-1500{degrees}C (thermal non-catalytic decomposition of methane) to 500-900{degrees}C. Transition metal based catalysts and various forms of carbon are among the candidate catalysts for the process. This approach can advantageously be used for the development of compact NG reformers for on-site production of hydrogen-methane blends at refueling stations and, also, for the production of hydrogen-rich gas for fuel cell applications. The author extended the search for active methane decomposition catalysts to various modifications of Ni-, Fe-, Mo- and Co-based catalysts. Variation in the operational parameters makes it possible to produce H{sub 2}-CH{sub 4} blends with a wide range of hydrogen concentrations that vary from 15 to 98% by volume. The author found that Ni-based catalysts are more effective at temperatures below 750{degrees}C, whereas Fe-based catalysts are effective at temperatures above 800{degrees}C for the production of hydrogen with purity of 95% v. or higher. The catalytic pyrolysis of liquid hydrocarbons (pentane, gasoline) over Fe-based catalyst was conducted. The author observed the production of a hydrogen-rich gas (hydrogen concentration up to 97% by volume) at a rate of approximately 1L/min.mL of hydrocarbon fuel.

Full Text Available Industrial production is one of the leading indicators of gross domestic product which reflects the overall economic performance of a country. In other words decreases or increases in industrial production point out a contracting or expanding economy. Therefore, changes in prices of oil and natural gas which are the crucial inputs to the industrial production are also important for the overall economy. This study examines the effects of changes in oil and natural gas prices on the industrial production in the 18 Eurozone member countries during the period January 2001-September 2013 by using panel regression. We found that oil prices and natural gas prices had negative effect on industrial production in the Eurozone member countries.

A series of vanadium-nickel-alumina (xVNA) catalysts were prepared by a single-step sol-gel method with a variation of vanadium content (x, wt%) for use in the hydrogen production by steam reforming of natural gas. The effect of vanadium content on the physicochemical properties and catalytic activities of xVNA catalysts in the steam reforming of natural gas was investigated. It was found that natural gas conversion and hydrogen yield showed volcano-shaped trends with respect to vanadium content. It was also revealed that natural gas conversion and hydrogen yield increased with decreasing nickel crystallite size.

New extraction technologies are making natural gas from shale and tight sand gas reservoirs in the United States (US) more accessible. As a result, the US has become the largest producer of natural gas in the world. This growth in natural gas production may result in increased leakage of methane, a potent greenhouse gas, offsetting the climate benefits of natural gas relative to other fossil fuels. Methane emissions from natural gas production are not well quantified because of the large variety of potential sources, the variability in production and operating practices, the uneven distribution of emitters, and a lack of verification of emission inventories with direct atmospheric measurements. Researchers at the NOAA Earth System Research Laboratory (ESRL) have used simple mass balance approaches in combination with isotopes and light alkanes to estimate emissions of CH4 from several natural gas and oil plays across the US. We will summarize the results of the available aircraft and ground-based atmospheric emissions estimates to better understand the spatial and temporal distribution of these emissions in the US.

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

The objective of this paper was to evaluate the performance of the natural gas industry using an inter-country comparison of productivity level and its determinants. Three methodologies: multilateral Toernqvist productivity analysis; managerial index system analysis; and non-parametric efficiency analysis, are employed to make a methodological cross-checking and to perform diversified analysis. From the empirical results, we identified the level and growth rate of productivity of individual firms. The results also indicated that the Korean gas industry has shown a relatively low level of productivity. From the results of managerial performance index analysis, we found that during the recent years of regulatory changes, the final price of gas has decreased dramatically while the productivity growth has not been enough to offset the effect of decreased output price, which has resulted in decreased profit. We also examine the extent of the allocative, scale, and managerial efficiency as source components of the overall efficiency based on the performance of best-practiced. With the results of this study, an effective policy measure could be established to improve the productivity and the overall managerial performance in the natural gas industry

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

Life cycle water consumption for shale gas and conventional natural gas.

Science.gov (United States)

Clark, Corrie E; Horner, Robert M; Harto, Christopher B

2013-10-15

Shale gas production represents a large potential source of natural gas for the nation. The scale and rapid growth in shale gas development underscore the need to better understand its environmental implications, including water consumption. This study estimates the water consumed over the life cycle of conventional and shale gas production, accounting for the different stages of production and for flowback water reuse (in the case of shale gas). This study finds that shale gas consumes more water over its life cycle (13-37 L/GJ) than conventional natural gas consumes (9.3-9.6 L/GJ). However, when used as a transportation fuel, shale gas consumes significantly less water than other transportation fuels. When used for electricity generation, the combustion of shale gas adds incrementally to the overall water consumption compared to conventional natural gas. The impact of fuel production, however, is small relative to that of power plant operations. The type of power plant where the natural gas is utilized is far more important than the source of the natural gas.

Utilizing natural gas huff and puff to enhance production in heavy oil reservoir

The L Block in the north structural belt of China's Tuha Basin is a super deep heavy oil reservoir. The gas to oil ratio (GOR) is 12 m{sup 3}/m{sup 3} and the initial bubble point pressure is only 4 MPa. The low production can be attributed to high oil viscosity and low flowability. Although steam injection is the most widely method for heavy oil production in China, it is not suitable for the L Block because of its depth. This paper reviewed pilot tests in which the natural gas huff and puff process was used to enhance production in the L Block. Laboratory experiments that included both conventional and unconventional PVT were conducted to determine the physical property of heavy oil saturated by natural gas. The experiments revealed that the heavy oil can entrap the gas for more than several hours because of its high viscosity. A pseudo bubble point pressure exists much lower than the bubble point pressure in manmade foamy oils, which is relative to the depressurization rate. Elastic energy could be maintained in a wider pressure scope than natural depletion without gas injection. A special experimental apparatus that can stimulate the process of gas huff and puff in the reservoir was also introduced. The foamy oil could be seen during the huff and puff experiment. Most of the oil flowed to the producer in a pseudo single phase, which is among the most important mechanisms for enhancing production. A pilot test of a single well demonstrated that the oil production increased from 1 to 2 cubic metres per day to 5 to 6 cubic metres per day via the natural gas huff and puff process. The stable production period which was 5 to 10 days prior to huff and puff, was prolonged to 91 days in the first cycle and 245 days in the second cycle. 10 refs., 1 tab., 12 figs.

Economic growth to raise U.S. oil products, natural gas demand

International Nuclear Information System (INIS)

Beck, R.J.

1994-01-01

An accelerating economy will raise consumption of oil products and natural gas in the US this year. Contributing to demand growth will be the slump that began late last year in prices for crude oil and petroleum products. Some price recovery is likely in 1994, but there's little reason to expect a major increase. With oil production falling and demand rising, imports will have to climb again this year. OGJ projects a 2.6% increase this year following a 6.6% increase last year. Imports are expected to fill a record high 49.3% of US oil demand this year. The paper discusses energy and the economy, overall energy use, energy by source, the electrification trend, energy supplies, imports, refining operations, the growth of margins, and the energy demand of motor gasoline, jet fuel, distillate fuels, residual fuel oils, other petroleum products, and natural gas

Constructing a Spatially Resolved Methane Emission Inventory of Natural Gas Production and Distribution over Contiguous United States

Methane is the second most powerful greenhouse gas after Carbon Dioxide. The natural gas production and distribution accounts for 23% of the total anthropogenic methane emissions in the United States. The boost of natural gas production in U.S. in recent years poses a potential concern of increased methane emissions from natural gas production and distribution. The Emission Database for Global Atmospheric Research (Edgar) v4.2 and the EPA Greenhouse Gas Inventory (GHGI) are currently the most commonly used methane emission inventories. However, recent studies suggested that both Edgar v4.2 and the EPA GHGI largely underestimated the methane emission from natural gas production and distribution in U.S. constrained by both ground and satellite measurements. In this work, we built a gridded (0.1° Latitude ×0.1° Longitude) methane emission inventory of natural gas production and distribution over the contiguous U.S. using emission factors measured by our mobile lab in the Marcellus Shale, the Denver-Julesburg Basin, and the Uintah Basin, and emission factors reported from other recent field studies for other natural gas production regions. The activity data (well location and count) are mostly obtained from the Drillinginfo, the EPA Greenhouse Gas Reporting Program (GHGRP) and the U.S. Energy Information Administration (EIA). Results show that the methane emission from natural gas production and distribution estimated by our inventory is about 20% higher than the EPA GHGI, and in some major natural gas production regions, methane emissions estimated by the EPA GHGI are significantly lower than our inventory. For example, in the Marcellus Shale, our estimated annual methane emission in 2015 is 600 Gg higher than the EPA GHGI. We also ran the GEOS-Chem methane simulation to estimate the methane concentration in the atmosphere with our built inventory, the EPA GHGI and the Edgar v4.2 over the nested North American Domain. These simulation results showed differences in

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

Production of natural gas from methane hydrate by a constant downhole pressure well

International Nuclear Information System (INIS)

Ahmadi, Goodarz; Ji, Chuang; Smith, Duane H.

2007-01-01

Natural gas production from the dissociation of methane hydrate in a confined reservoir by a depressurizing downhole well was studied. The case that the well pressure was kept constant was treated, and two different linearization schemes in an axisymmetric configuration were used in the analysis. For different fixed well pressures and reservoir temperatures, approximate self similar solutions were obtained. Distributions of temperature, pressure and gas velocity field across the reservoir were evaluated. The distance of the decomposition front from the well and the natural gas production rate as functions of time were also computed. Time evolutions of the resulting profiles were presented in graphical forms, and their differences with the constant well output results were studied. It was shown that the gas production rate was a sensitive function of well pressure and reservoir temperature. The sensitivity of the results to the linearization scheme used was also studied

The golden age of natural gas

International Nuclear Information System (INIS)

Anon.

1999-01-01

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.)

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

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

This Canadian Standard on the production, storage and handling of liquefied natural gas (LNG) was prepared by the Technical Committee on Liquefied Natural Gas under the jurisdiction of the Steering Committee on Oil and Gas Industry Systems and Materials. It establishes the necessary requirements for the design, installation and safe operation of LNG facilities. The Standard applies to the design, location, construction, operation and maintenance of facilities at any location of the liquefaction of natural gas and for the storage, vaporization, transfer, handling and truck transport of LNG. The training of personnel involved is also included as well as containers for LNG storage, including insulated vacuum systems. It includes non-mandatory guidelines for small LNG facilities but does not apply to the transportation of refrigerants, LNG by rail, marine vessel or pipeline. This latest edition contains changes in working of seismic design requirements and minor editorial changes to several clauses to bring the Standard closer to the US National Fire Protection Association's Committee on Liquefied Natural Gas Standard while maintaining Canadian regulatory requirements. The document is divided into 12 sections including: general requirements; plant site provisions; process equipment; stationary LNG storage containers; vaporization facilities; piping system and components; instrumentation and electrical services; transfer of LNG and refrigerants; fire protection, safety and security; and, operating, maintenance and personnel training. This Standard, like all Canadian Standards, was subject to periodic review and was most recently reaffirmed in 2003. 6 tabs., 6 figs., 3 apps.

Natural gas outlook

International Nuclear Information System (INIS)

Molyneaux, M.P.

1998-01-01

An overview of natural gas markets in Canada and in the United States was provided. The major factors that determine the direction of natural gas prices were depicted graphically. Price volatility has decreased in recent months. As expected, April through November total energy consumption reached historically high levels. Demand for natural gas during the summer of 1997 was not as strong as anticipated. Nuclear energy appears to be on the slippery slope, with natural gas-driven electricity projects to fill the void. Hydroelectricity had a strong showing in 1997. Prospects are less bright for 1998 due to above average temperatures. Canadian natural gas export capacity has increased 5.5 times between 1986 and estimated 1999 levels. Despite this, in 1997, deliveries to the United States were marginally behind expectations. Natural gas consumption, comparative fuel prices, natural gas drilling activity, natural gas storage capacity, actual storage by region, and average weekly spot natural gas prices, for both the U. S. and Canada, were also provided. With regard to Canada, it was suggested that Canadian producers are well positioned for a significant increase in their price realization mostly because of the increase in Canada's export capacity in 1997 (+175 Mmcf/d), 1998 (1,060 Mmcf/d) and potentially in 1999 or 2000, via the Alliance Pipeline project. Nevertheless, with current production projections it appears next to impossible to fill the 10.9 Bcf/d of export capacity that will be potentially in place by the end of 1999. tabs., figs

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

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)

Life-cycle greenhouse gas emissions of shale gas, natural gas, coal, and petroleum.

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.

Developing electricity production with natural gas in the southern mediterranean countries. An example of north-south cooperation in the electricity and natural gas sectors

International Nuclear Information System (INIS)

Grenon, M.; Nogaret, E.

1996-01-01

The countries of the Southern Mediterranean region are facing an important increase of electricity demand due to their socio-economic development. In order to increase the production capacity at a minimum cost while preserving the environment, most countries of the region are planning gas fired power stations due to the important natural gas resources in the area. Overall investments in new power plants could reach the total of 100 billion dollars, up to the horizon 2010. The development of both the power plants and the infrastructure to produce and transport the natural gas needed is more and more performed through cooperation between companies of the two shores of the Mediterranean and represent an example of North- South cooperation in the energy field. This cooperation is taking place through technical assistance programs and also joint financing and management of the infrastructure required. A special importance is given to the development of highly efficient combined cycle power plants in the Southern Mediterranean countries and to the increase of the activities related to the exploration and production of natural gas.

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

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

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

A series of overhead viewgraphs accompanied this presentation which presented an update of North American natural gas supply. Some of the graphs depicted the following: (1) natural gas consumption in the United States, (2) U.S. imports of Canadian natural gas, (3) natural gas prices differential: Henry Hub versus Empress, (4) natural gas production in the U.S., and (5) Baker Hughes active rig count, U.S. gas rigs. First Energy's view of U.S. natural gas supply is that the estimate of 50.0 Bcf/d for U.S. domestic production is looking too high. The first quarter 1999 exit production rates are behind expectations. U.S. domestic natural gas expenditure budgets are still down by more than 40 per cent compared to 1998 levels. The impact that this will have on prices was discussed. 21 figs

Pasternak, Michael

2013-01-01

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

Some specific processes are required to obtain pure hydrogen and the most usual one is the natural gas reforming, where natural gas reacts with superheated steam producing H{sub 2}, CO, CO{sub 2} and H{sub 2}O. This paper presents exergy and thermoeconomic analysis of a complete hydrogen production unit of a petroleum refinery. The hydrogen production unit analysed in this paper has to supply 550,000 Nm{sup 3} of hydrogen per day to purify diesel oil. Based on a synthesis plant of the hydrogen production unit, the exergy efficiency of each component and of the overall plant are calculated. The hydrogen production cost is determined by means of a thermoeconomic analysis in which the equality cost partition method is employed, including capital and operational costs, in order to determine the production cost of hydrogen and other products of the plant.(author)

Kostowski, Wojciech J.; Usón, Sergio; Stanek, Wojciech; Bargiel, Paweł

2014-01-01

The paper presents a novel concept for thermodynamic evaluation of a selected energy system. The presented method has been developed by integration of the Thermo-Economic Analysis with the theory of Thermo-Ecological Cost. It can be applied as a thermodynamic evaluation method of rational resources management within any production system. It takes into account both the interrelation of irreversibility within the analyzed system and its influence on the global effects related to the depletion of non-renewable natural resources. The proposed method has been applied to evaluate the production of electricity in the process of natural gas transmission at pressure reduction stations. The expansion system is based on an existing plant integrated with a CHP module, characterized by a performance ratio of 89.5% and exergy efficiency of 49.2%. Within the paper, this expansion plant is supplied with natural gas transported from a natural deposit through a case-study transmission system with 4 compressor stations. The TEC (thermoecological cost) method was applied in conjunction with thermoeconomic analysis. As a result, TEC of the electricity generated in the expanders was determined at 2.42 kJ/kJ, TEC of electricity from the CHP module is 1.77, and the TEC of medium-pressure natural gas distributed to consumers is 1.022. - Highlights: • The chain of NG transmission with an exergy recovery expansion plant was analyzed. • New methodology coupling the TEC (thermoecological cost) and thermoeconomics. • Decomposition of the TEC formation process. • Case-study transmission system yields TEC of natural gas = 1.0222. • Expansion plant yields TEC of electricity 2.42 (expanders) and 1.77 (CHP module)

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.

As a result of oil and gas production, radioactive daughter elements from the uranium and thorium decay series can be mobilized and transported away from the reservoir. Due to changes in flow regime, temperature, pressure or chemical environment NORs (Naturally Occurring Radionuclides) may build up in products, by-products or waste streams from gas and oil production and processing facilities. Products containing NORs are commonly denoted by the acronym NORM (Naturally Occurring Radioactive Materials).

International Nuclear Information System (INIS)

Pleckaitis, A.

2004-01-01

The role of natural gas in power generation was discussed with reference to price implications and policy recommendations. New natural gas supply is not keeping pace with demand. Production is leveling out in traditional basins and industry investment is not adequate. In addition, energy deregulation is creating disconnects. This presentation included a map depicting the abundant natural gas reserves across North America. It was noted that at 2002 levels of domestic production, North America has approximately 80 years of natural gas. The AECO consensus wholesale natural gas price forecast is that natural gas prices in 2010 will be lower than today. The use of natural gas for power generation was outlined with reference to fuel switching, distributed generation, and central generation. It was emphasized that government, regulators and the energy industry must work together to address policy gaps and eliminate barriers to new investment. 13 figs

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

Natural gas production and anomalous geothermal gradients of the deep Tuscaloosa Formation

Burke, Lauri

2011-01-01

For the largest producing natural gas fields in the onshore Gulf of Mexico Basin, the relation between temperature versus depth was investigated. Prolific natural gas reservoirs with the highest temperatures were found in the Upper Cretaceous downdip Tuscaloosa trend in Louisiana. Temperature and production trends from the deepest field, Judge Digby field, in Pointe Coupe Parish, Louisiana, were investigated to characterize the environment of natural gas in the downdip Tuscaloosa trend. The average production depth in the Judge Digby field is approximately 22,000 ft. Temperatures as high as 400 degrees F are typically found at depth in Judge Digby field and are anomalously low when compared to temperature trends extrapolated to similar depths regionally. At 22,000 ft, the minimum and maximum temperatures for all reservoirs in Gulf Coast producing gas fields are 330 and 550 degrees F, respectively; the average temperature is 430 degrees F. The relatively depressed geothermal gradients in the Judge Digby field may be due to high rates of sediment preservation, which may have delayed the thermal equilibration of the sediment package with respect to the surrounding rock. Analyzing burial history and thermal maturation indicates that the deep Tuscaloosa trend in the Judge Digby field is currently in the gas generation window. Using temperature trends as an exploration tool may have important implications for undiscovered hydrocarbons at greater depths in currently producing reservoirs, and for settings that are geologically analogous to the Judge Digby fiel

Natural gas market assessment. Canadian natural gas market mechanisms: Recent experiences and developments

International Nuclear Information System (INIS)

1993-11-01

The increase in natural gas demand and the associated expansions of most of the pipeline systems serving western Canada have reduced the excess deliverability or excess productive capacity that existed at the time of deregulation of the natural gas industry in 1985. Based on an industry survey, the responses of natural gas buyers and sellers to recent supply difficulties are described. Specific production, transportation, and contractual difficulties were encountered in winter 1992/93 as production was stretched to meet record levels of demand during periods of very cold temperatures and as short-term spot prices reached very high levels. Problems at this time included wellhead freezeups, pipeline outages, and inadequate contract terms and conditions. Methods used to maintain gas flows to end users are reviewed, including a discussion of force majeure, spot gas purchases, storage, supply curtailment, and special loan arrangements. In 1992/93, in most instances where the responsibility fell on the end-user to solve the supply problem, the difficulty was shifted to local distribution companies who have traditionally had more experience with such situations. No cases were identified where either a firm or interruptible end-user was forced to curtail gas consumption because of inadequate supply. New market mechanisms are emerging that will enable buyers and sellers of western Canadian gas to avoid many of the problems encountered in 1992/93. These include prearranged backstopping arrangements, short-term spot markets, access to other gas basins, standardized gas contracts, electronic trading, and price risk management tools. 11 figs

Natural Gas Versus Nuclear New Build Versus Life Extension

Barron, B.

2013-01-01

Proven natural gas reserves and production in the USA have continued to increase in recent years. This is due to the exploration of shale formations and the expanded use of hydraulic fracking technology. Looking forward, we can expect that high crude oil prices will sustain natural gas production at current levels (approximately 25% of natural gas production in the USA is a by-product of crude oil drilling), and the natural gas liquid cuts are priced with crude oil. Continued drilling in the near term for natural gas is required by lease obligations and by commitments to investors

Forecasting world natural gas supply

Al-Fattah, S. M.; Startzman, R. A.

2000-01-01

Using the multi-cyclic Hubert approach, a 53 country-specific gas supply model was developed which enables production forecasts for virtually all of the world's gas. Supply models for some organizations such as OPEC, non-OPEC and OECD were also developed and analyzed. Results of the modeling study indicate that the world's supply of natural gas will peak in 2014, followed by an annual decline at the rate of one per cent per year. North American gas production is reported to be currently at its peak with 29 Tcf/yr; Western Europe will reach its peak supply in 2002 with 12 Tcf. According to this forecast the main sources of natural gas supply in the future will be the countries of the former Soviet Union and the Middle East. Between them, they possess about 62 per cent of the world's ultimate recoverable natural gas (4,880 Tcf). It should be noted that these estimates do not include unconventional gas resulting from tight gas reservoirs, coalbed methane, gas shales and gas hydrates. These unconventional sources will undoubtedly play an important role in the gas supply in countries such as the United States and Canada. 18 refs., 2 tabs., 18 figs

Natural gas production verification tests

1992-02-01

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

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.

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)

Emissions implications of future natural gas production and use in the U.S. and in the Rocky Mountain region.

Enhanced prospects for natural gas production raise questions about the balance of impacts on air quality, as increased emissions from production activities are considered alongside the reductions expected when natural gas is burned in place of other fossil fuels. This study explores how trends in natural gas production over the coming decades might affect emissions of greenhouse gases (GHG), volatile organic compounds (VOCs) and nitrogen oxides (NOx) for the United States and its Rocky Mountain region. The MARKAL (MARKet ALlocation) energy system optimization model is used with the U.S. Environmental Protection Agency's nine-region database to compare scenarios for natural gas supply and demand, constraints on the electricity generation mix, and GHG emissions fees. Through 2050, total energy system GHG emissions show little response to natural gas supply assumptions, due to offsetting changes across sectors. Policy-driven constraints or emissions fees are needed to achieve net reductions. In most scenarios, wind is a less expensive source of new electricity supplies in the Rocky Mountain region than natural gas. U.S. NOx emissions decline in all the scenarios considered. Increased VOC emissions from natural gas production offset part of the anticipated reductions from the transportation sector, especially in the Rocky Mountain region.

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.

Natural-gas supply-and-demand problems

International Nuclear Information System (INIS)

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

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.

Role of natural gas in meeting an electric sector emissions ...

Science.gov (United States)

With advances in natural gas extraction technologies, there is an increase in availability of domestic natural gas, and natural gas is gaining a larger share of use as a fuel in electricity production. At the power plant, natural gas is a cleaner burning fuel than coal, but uncertainties exist in the amount of methane leakage occurring upstream in the extraction and production of natural gas. At high leakage levels, these methane emissions could outweigh the benefits of switching from coal to natural gas. This analysis uses the MARKAL linear optimization model to compare the carbon emissions profiles and system-wide global warming potential of the U.S. energy system over a series of model runs in which the power sector is asked to meet a specific CO2 reduction target and the availability of natural gas changes. Scenarios are run with a range of upstream methane emission leakage rates from natural gas production. While the total CO2 emissions are reduced in most scenarios, total greenhouse gas emissions show an increase or no change when both natural gas availability and methane emissions from natural gas production are high. Article presents summary of results from an analyses of natural gas resource availability and power sector emissions reduction strategies under different estimates of methane leakage rates during natural gas extraction and production.

This article aims to analyze the possibility of insertion of hydrogen in the vehicular natural gas or even the insertion of the hydrogen in the compressed natural gas used in Brazil. For the production of this hydrogen, the spilled turbinable energy from Itaipu would be harnessed. The calculation of production can be extended to other power plants which are close to the natural gas pipelines, where the hydrogen would be introduced. Then, it was analyzed the consumption of natural gas in vehicles in Brazil, the regulation of transportation, the sales of compressed natural gas to fuelling station, the specifications that the piped gas should follow to be sold, and how much hydrogen could be accepted in the mix.

The widening gap between EU gas production and consumption may require an 87% increase of import volumes between 2006 and 2030, and there are great uncertainties regarding the amounts of gas that can be expected from new suppliers. The potential of increased production from Norway and Algeria is limited; hence, Russia is likely to play a crucial part of meeting the anticipated growing gas demand of the EU. A field-by-field study of 83 giant gas fields shows that the major producing Russian gas fields are in decline, and by 2013 much larger supplies from the Yamal Peninsula and the Shtokman field will be needed in order to avoid a decline in production. Gas from fields in Eastern Siberia and the Far East will mainly be directed to the Asian and Pacific Rim markets, thereby limiting its relevance to the European and CIS markets. As a result, the maximum export increase to the European and CIS markets amounts only to about 45% for the period 2015-2030. The discourse surrounding the EU's dependence on Russian gas should thus not only be concerned with geopolitics, but also with the issue of resource limitations. - Research highlights: {yields}Natural gas production in the Nadym Pur Taz region (Western Siberia) will start to decline within a few years. {yields}New production from the Yamal peninsula is critical to ensure gas exports to Europe. {yields}Additional production in East Siberia and the Far East will not be available for the European market. {yields}Rapid gas demand growth in China might also lead to competition for gas from Western Siberia.

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.

Most of Brazilian gas fields are low-permeability or tight sandstone reservoirs and some of them should be gas condensate reservoir. In this type of natural gas reservoir, part of the gaseous hydrocarbon mixture is condensate and the liquid hydrocarbon accumulates near the well bore that causes the loss of productivity. The liquid hydrocarbon formation inside the reservoir should be well understood such as the knowledge of the variables that causes the condensate formation and its importance in the natural gas production. This work had as goal to better understanding the effect of condensate accumulation near a producer well. The influence of the porosity and the absolute permeability in the gas production was studied in three distinct gas reservoirs: a dry gas reservoir and two gas condensate reservoirs. The refinement of the simulation grid near the producer well was also investigated. The choice of simulation model was shown to be very important in the simulation of gas condensate reservoirs. The porosity was the little relevance in the gas production and in the liquid hydrocarbon formation; otherwise the permeability was very relevant. (author)

Distribution forms for biogas and natural gas in Sweden

International Nuclear Information System (INIS)

Benjaminsson, Johan; Nilsson, Ronny

2009-11-01

Since biogas and natural gas basically have the same characteristics, they can be distributed in the same system. In the parts of the country where there is an extensive natural gas distribution network, the infrastructure for natural gas can be used for distribution of biogas. In order to increase the use of renewable energy, it is a political ambition to increase the share of biogas in the natural gas network, and, in the long run, entirely replace natural gas with biogas. Much of biogas production in the country is, however, not reached by the existing natural gas network, and this is also the case for a large part of the potential for future biogas production. In these areas the gas is transported in more or less extensive local gas distribution networks and by truck in compressed or liquid form. Transport of compressed and liquefied gas is efficient in some cases and development of these systems is an ongoing process. A number of facilities are planned for production of large quantities of biogas, several hundred GWh/year, through digestion and gasification processes. These plants will be located either in conjunction with major gas consumers or in the vicinity of the existing natural gas grid. The potential for biogas production is, however, present throughout the country and in order to meet market demand biogas requires efficient distribution systems

Natural Gas Hydrate as a Storage Mechanism for Safe, Sustainable and Economical Production from Offshore Petroleum Reserves

Directory of Open Access Journals (Sweden)

Michael T. Kezirian

2017-06-01

Full Text Available Century Fathom presents an innovative process to utilize clathrate hydrates for the production, storage and transportation of natural gas from off-shore energy reserves in deep ocean environments. The production scheme was developed by considering the preferred state of natural gas in the deep ocean and addressing the hazards associated with conventional techniques to transport natural gas. It also is designed to mitigate the significant shipping cost inherent with all methods. The resulting proposed scheme restrains transport in the hydrate form to the ocean and does not attempt to supply energy to the residential consumer. Instead; the target recipients are industrial operations. The resulting operational concept is intrinsically safer by design; environmentally sustainable and significantly cost-effective compared with currently proposed schemes for the use of natural gas hydrates and has the potential to be the optimal solution for new production of reserves; depending on the distance to shore and capacity of the petroleum reserve. A potential additional benefit is the byproduct of desalinated water.

Ozturk, M.

2010-01-01

Society has become concerned about the issues of natural resource depletion and environmental degradation. The environmental performance of products or processes has become a key issue, which is why ways to minimize the effects on the environment are investigated. The most effective tool for this purpose is called life cycle assessment (LCA). This concept considers the entire life cycle of product or process. The life cycle of a product begins with the extraction of raw materials from the earth to create the product and ends at the point when all materials are returned to the earth. LCA makes it possible to estimate the cumulative environmental impacts resulting from all stages in the product life cycle, often including impacts not considered in more traditional analyses. Therefore, LCA provides a comprehensive view of the environmental aspects of the product or process and a more accurate picture of the true environmental trade-offs in product selection. In the case of this study, life cycle assessments of hydrogen production via natural gas reforming process are investigated for environmental affect.

Natural gas industry competitiveness study

International Nuclear Information System (INIS)

1999-09-01

A national study on the competitiveness of the natural gas industry was undertaken by the BC Oil and Gas Commission in cooperation with, and with the encouragement of the Canadian Association of Petroleum Producers (CAPP). The objective of the study was to compare the cost competitiveness of natural gas exploration , production, gathering and processing in British Columbia to the costs of the same processes in Alberta. The study was carried out by building an 'expected case' for each gas producing area in British Columbia and Alberta by averaging past events in such specific areas as pool sizes, production profiles, loads, drilling success rates, gas compositions, land, drilling, exploration and production/gathering costs, third party production/gathering and processing fees and abandonment costs; by constructing a cash flow model for each case, calculating unit cost, and ranking cases. The report provides the details of the methodology, displays the results of the investigation in graphical form, comments on the results factoring in also labour costs and cost differences due to resource characteristics, identifies some trends such as an increase in the proportion of connections to smaller plants, and provides suggestions for improvements

The clay-product industry is responsible to large part of the thermal energy consumption, especially on drying and burning process. In spite of the success obtained with the burning of wood like principal fuel for tunnel kilns, the clay-product industries of Santa Catarina have looked for alternatives to substitute it. The interest appears especially due to imminent shortage of the wood on the market and due to possibility of use natural gas as a good and environmentally favorable alternative to reduce the energy specific consumption of the kilns, to increase the production and to improve the quality of the ceramic products. Nowadays, the natural gas is more expensive when compared with the wood. However, we believe that additional studies can place this fuel as a viable alternative to the clay-product industries.

In Croatia, natural gas is an important source of energy, where its use exceeds other sources by one third. Composed primarily of the methane, natural gas from Croatian Podravina gas fields, beside other impurities, contains small amounts of radioactive elements. At Gas Treatment Plant (GTP) Molve, technological procedures for purification of natural gas and its distribution are performed. With yearly natural gas production of 3.5 109 m3 GTP Molve is major Croatian energy resource. Its safety and environment impact is matter of concern. Using different radioactivity measuring techniques the exposure of population to ionizing radiation were calculated at Central Natural Gas Station Molve and the underground wells. The measurement techniques included in-situ gamma spectrometric measurements, from which contribution to absorbed dose of the natural radionuclide in soil were calculated. Exposure dose measurements were performed using T.L.-dosimeters, and L.A.R.A. electronic dosimeters as well as field dose rate meter. Comparing used different radioactivity measuring methods, the correlations have been calculated. (authors)

Origin of natural gas; Tennen gas no kigen

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.

Issues regarding future natural gas prices for North America were discussed. Various aspects of the issue including the relationship between storage, weather and prices, received attention. It was noted that strong demand-growth will be needed to support near-term Canadian export increases without price declines. The issue of Gulf Coast production was also discussed. Power generation using natural gas as fuel is expected to support strong growth in the demand for natural gas. tabs., figs

Norwegian Natural Gas. Liberalization of the European Gas Market

International Nuclear Information System (INIS)

Austvik, Ole Gunnar

2003-01-01

Leading abstract. This book focuses on issues that are important for Norway as a major gas exporter and to the development of a liberalized European market. Chapter 2 explains main features of the European gas market. Natural gas is sold in regional markets with independent pricing structure and particularities. In Europe, this has led to large investments for the producers and long-term contracts. The strong market growth and EU's actions to liberalize the market may change this. The organization of the Norwegian gas production and sale is discussed, as well as the reorganization taking place in 2001. Pricing mechanisms are discussed in Chapter 3, both in the ''old'' / existing structure and how a liberalization of the market may change price formation. The increased importance of energy taxation in EU countries is covered in Chapter 4. Even though natural gas is the most environmentally friendly of the fossil fuels, the use of natural gas may be taxed far harder in the future. The report discusses price effects of such a development. Chapter 5 discusses whether or not a gas producer, like Norway, necessarily must earn a resource rent. With the use of economic theory for exhaustible resources it is shown how prices to consumers may increase at the same time as prices to producers drop, where the difference is made up by higher gas taxes to the consuming countries. Transportation of natural gas involves considerable scale advantages and there are often scope advantages from production, storage and sale, as well. Chapter 6 discusses how competition and regulation may influence the functioning and social efficiency of the market, and the concentration of market power. When companies become large, they may exploit market power, supported by the authorities of their respective countries. Chapter 7 focuses on regulatory challenges for the EU, and how the transporters may change between conflicting and cooperation with the EU. Chapter 8 focuses on schedules for

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

Leaks in natural gas infrastructure release methane (CH4), a potent greenhouse gas, into the atmosphere. The estimated fugitive emission rate associated with the production phase varies greatly between studies, hindering our understanding of the natural gas energy efficiency. This study presents a new application of inverse methodology for estimating regional fugitive emission rates from natural gas production. Methane observations across the Marcellus region in northeastern Pennsylvania were obtained during a three week flight campaign in May 2015 performed by a team from the National Oceanic and Atmospheric Administration (NOAA) Global Monitoring Division and the University of Michigan. In addition to these data, CH4 observations were obtained from automobile campaigns during various periods from 2013-2015. An inventory of CH4 emissions was then created for various sources in Pennsylvania, including coalmines, enteric fermentation, industry, waste management, and unconventional and conventional wells. As a first-guess emission rate for natural gas activity, a leakage rate equal to 2% of the natural gas production was emitted at the locations of unconventional wells across PA. These emission rates were coupled to the Weather Research and Forecasting model with the chemistry module (WRF-Chem) and atmospheric CH4 concentration fields at 1km resolution were generated. Projected atmospheric enhancements from WRF-Chem were compared to observations, and the emission rate from unconventional wells was adjusted to minimize errors between observations and simulation. We show that the modeled CH4 plume structures match observed plumes downwind of unconventional wells, providing confidence in the methodology. In all cases, the fugitive emission rate was found to be lower than our first guess. In this initial emission configuration, each well has been assigned the same fugitive emission rate, which can potentially impair our ability to match the observed spatial variability

Natural gas is increasingly becoming a major contributor in the industrial development of most Middle Eastern countries. Demand there will rise steeply in coming years. This is because of the abundant and growing natural gas resources in the region, the economic benefits of using local resources, as well as increased emphasis on a cleaner environment. Today, proved reserves of natural gas in the Middle East are 45 trillion cu meters (tcm), or 1,488 trillion cu ft (tcf). This is over 30% of the world's natural gas reserves. A table presents data on reserves and production of natural gas in the region. About 20% of this gross production is rein-injecting for oil field pressure maintenance, 13% is flared or vented, and 7% is accounted as losses. The remaining 60% represents consumption in power generation, water desalination, petrochemicals and fertilizers production, aluminum and copper smelting, and fuel for refineries and other industries. The use of natural gas in these various industries is discussed. Thirteen tables present data on gas consumption by country and sector, power generation capacity, major chemicals derived from natural gas, and petrochemical plant capacities

Highlights: • Low-temperature processes for of high CO_2 content natural gas have been modelled. • Energy and exergy analyses have been performed. • The Dual Pressure distillation scheme has the best thermodynamic performances. • There is a synergy between cryogenic natural gas purification and LNG production. - Abstract: Due to the rapid increase of the World’s primary energy demand of the last decades, low-temperature processes for the purification of natural gas streams with high carbon dioxide content has gained interest, since they allow to make profitable exploitation of low-quality gas reserves. Low temperature purification processes allow the direct production of a methane stream at high purity and at low-temperature, suitable conditions for the direct synergistic integration with natural gas cryogenic liquefaction processes, while CO_2 is obtained in liquid phase and under pressure. In this way, it can be pumped for transportation, avoiding significant compression costs as for classical CO_2 capture units (where carbon dioxide is discharged in gas phase and at atmospheric pressure), and further uses such as Enhanced Oil Recovery (EOR) or underground storage. In this paper, the three most common natural gas low-temperature purification techniques have been modelled and their performances have been evaluated through energy and exergy analyses. Specifically, the dual pressure low-temperature distillation process, the anti-sublimation process and a hybrid configuration have been considered. It is found that the dual pressure low-temperature distillation scheme reach the highest thermodynamic performances, resulting in the best values of exergy efficiency and equivalent methane requirements with respect to the other configurations. This is mainly due to the distributed temperature profile along a distillation column, resulting in a less irreversible heat exchanging process.

Combined utilization of biogas and natural gas

The Danish natural gas network has been established during the past 10 years. Running parallel with this a small but growing production of biogas from centralized biogas plants and landfills has been developed. The annual biogas production is expected to keep growing and increase tenfold in the next 25 year period with a reduction of green house gas emissions as one of the important incentives. The last years' development and expansion of the Danish biogas sector has shown a need for combined utilization of biogas and natural gas. If larger volumes of biogas are present, upgrading and distribution by the natural gas network may be an alternative to combined utilization. (au) 12 refs

1999-01-01

The objective of this paper is to evaluate the performance of natural gas transportation utilities, focusing on the three-key strategic performance measures of profit, productivity, and price differential. We propose a methodology that expresses the three performance measures in a unified single equation using the Edgeworth index. The proposed methodology is applied to an international comparison of the performance of 28 natural gas transportation utilities operating in eight countries in which the business environments differ greatly. The empirical results show the possible causes of performance differences and may shed some light on the direction of regulatory policy, especially for developing countries that have relatively short histories in the natural gas industry, such as Korea.

This PowerPoint presentation identified natural gas as part of the electricity solution. It reviewed price implications and policy recommendations. New natural gas supply is not keeping pace with demand. Production is leveling out in traditional basins and industry investment is not adequate. In addition, energy deregulation is creating disconnects. This presentation included a map depicting the abundant natural gas reserves across North America. It was noted that at 2002 levels of domestic production, North America has approximately 80 years of natural gas. The AECO consensus wholesale natural gas price forecast is that natural gas prices in 2010 will be lower than today. The use of natural gas for power generation was outlined with reference to fuel switching, distributed generation, and central generation. It was emphasized that government, regulators and the energy industry must work together to address policy gaps and eliminate barriers to new investment. tabs., figs

Future considerations: Imperial finds new promise in natural gas

International Nuclear Information System (INIS)

Martin, J.

1988-01-01

After decades of having natural gas a minor part of its operations, Imperial Oil has reevaluated the importance of that resource within the company's strategy. A comprehensive business review of the industry was conducted in 1987 and prompted Imperial's subsidiary, Esso Resources Canada, to adopt the goal of becoming an industry leader in natural gas reserves, production, and marketing. Imperial's natural gas business started in 1921, when it assumed control of the company whose Turner Valley gas find sparked an oil rush in 1914. By the early 1940s, when Turner Valley was still Canada's only major oil field, Imperial was considering the manufacture of synthetic oil from natural gas, but then it discovered the first well of the Leduc oil boom in 1947. Imperial built the first gas conservation plant in Canada in 1950, but largely left other companies to develop gas fields. The deregulated gas market of the mid-1980s saw Imperial buying its first major acquisition in over 20 years, Sulpetro Ltd.; this boosted Imperial's annual gas production and its reserves by a third. A further purchase of Ocelot Industries increased overall gas production by another 20%. Imperial also made substantial gas finds in the Mackenzie Delta, and the company's holdings at Obed (Alberta) will add 8% to gas production

FSU's natural gas liquids business needs investment

Plotnikov, V.S.; Berman, M.; Angerinos, G.F.

1995-01-01

Production of natural gas liquids has fallen seriously behind its potential in the former Soviet Union (FSU). Restoration of the gas liquids business thus represents a rich investment opportunity. Capital, however, must come from international sources, which remain uncertain about the FSU's legal, commercial, and political systems. If these hurdles can be overcome, FSU output of liquid petroleum gas alone might double between 1990 and 2010. In the FSU, LPG is produced from associated and nonassociated natural gas, condensate, and refinery streams. It also comes from what is known in the FSU as ShFLU--a mixture of propane, butane, pentane, and hexane produced at gas processing plants in Western Siberia and fractionated elsewhere. The paper reviews FSU production of gas liquids focusing on West Siberia, gives a production outlook, and describes LPG use and business development

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.

2006-07-01

Natural gas is essential to the world economy. Gas now accounts for almost a quarter of OECD primary energy requirements and is expected to become the second most important fuel in the world in the next decade. Industrial and residential consumers increasingly rely on natural gas to keep their houses warm, their lights on and their factories running. Meanwhile the gas industry itself has entered a new phase. Where gas used to be restricted to regional markets, it is now increasingly traded on a global scale. While gas production and transport requires long-term investment, now it is optimised on a short-term basis. Demand continues to grow, but local gas production has become much more expensive. How should we react? How will demand be satisfied? What changes are required to promote flexibility and trade? What are the implications for gas security, investment and interdependence? At stake is an opportunity to diversify supply and demand - but this goal is threatened by barriers to competition and investment. This book is the first of a new IEA publication series. It takes an unprecedented look at developments in natural gas to 2010, analysing not only the three IEA regions (Asia Pacific, North America and Europe) but also broader global trends, such as the interaction of pipeline gas with LNG which binds the regions together. The Review provides invaluable insights for understanding this dynamic market.

Two computable general equilibrium models, one global and the other providing U.S. regional detail, are applied to analysis of the future of U.S. natural gas. The focus is on uncertainties including the scale and cost of gas resources, the costs of competing technologies, the pattern of greenhouse gas mitigation, and the evolution of global natural gas markets. Results show that the outlook for gas over the next several decades is very favorable. In electric generation, given the unproven and relatively high cost of other low-carbon generation alternatives, gas is likely the preferred alternative to coal. A broad GHG pricing policy would increase gas use in generation but reduce use in other sectors, on balance increasing its role from present levels. The shale gas resource is a major contributor to this optimistic view of the future of gas. Gas can be an effective bridge to a lower emissions future, but investment in the development of still lower CO 2 technologies remains an important priority. International gas resources may well prove to be less costly than those in the U.S., except for the lowest-cost domestic shale resources, and the emergence of an integrated global gas market could result in significant U.S. gas imports. - Highlights: → The shale gas resource is a major contributor to an optimistic view of the future of natural gas. → A broad carbon policy would increase natural gas use in power generation. → Natural gas can be an effective bridge to a lower emissions future. → In the next decade there is a potential for small U.S. gas exports. → An integrated global gas market could result in significant U.S. gas imports by 2030-2050.

Techno-economic evaluation of hybrid systems for hydrogen production from biomass and natural gas

Energy Technology Data Exchange (ETDEWEB)

Kassem, N. [Royal Institute of Technology, Stockholm (Sweden). Dept. of Energy Processes

Hydrogen (H{sub 2}) is an alternative energy carrier, which is expected to significantly contribute to globally sustainable energy systems. It is environmentally friendly with high-energy density that makes it an excellent integrating fuel in transportation and power generation systems. This paper presents an assessment of the techno-economic viability of H{sub 2} production technologies based on hybrid systems using gasified biomass and natural gas combined with high temperature electrochemical shift. Assessment of the well-established thermal processes, high-temperature steam electrolysis (HTEL), and the plasma catalytic reforming (PCR) of light hydrocarbons developed at MIT are included for comparison. The results show that the PCR and HTEL processes are as cost-effective as the thermal steam reforming for H{sub 2} production when deployed on a commercial scale. The natural gas steam reforming (NGSR) is still the most favorable choice in energy and financial terms, while gasified biomass (GB) provides the highest production costs due to the intensive capital cost investments. The cost of H{sub 2} storage in the form of compressed gas or liquefied H{sub 2} also contributes significantly to total cost per kg produced H{sub 2}. 9 refs., 7 figs., 2 tabs.

This work presents an experimental approach aiming the production of a gas mixture composed of H 2 and CH 4 , which should serve as natural gas substitute in industrial applications. Therefore, a lab-scale process chain employing a water gas shift unit, scrubbing units, and a pressure swing adsorption unit was operated with tar-rich product gas extracted from a commercial dual fluidized bed biomass steam gasification plant. A gas mixture with a volumetric fraction of about 80% H 2 and 19% CH 4 and with minor fractions of CO and CO 2 was produced by employing carbon molecular sieve as adsorbent. Moreover, the produced gas mixture had a lower heating value of about 15.5MJ·m -3 and a lower Wobbe index of about 43.4MJ·m -3 , which is similar to the typical Wobbe index of natural gas.

Recent projection of the market in global scale shows a tendency in natural gas using replacing mostly the fuel oil. Its market share well increase from 21.1% in 1994 to 24.0% in 2010. The annual energetic use will reach 29.23 x 10{sup 9} Gcal in 2010 (8990 million Nm{sup 3} natural gas/day) versus 18.90 x 10{sup 9} Gcal in 1994 (5810 million Nm{sup 3} natural gas/day). For Brazil, its consumption will increase from 8.7 million Nm{sup 3} natural gas/day in 1994 to 35.9 million Nm{sup 3} natural gas/day in 2010. Projects like Brazil-Bolivia natural gas pipeline, will supply 18 million Nm{sup 3} natural gas/day, which expected to start-up before the year 2000. This projects will supply the Brazilian southern regions, that do not consume natural gas at the current moment. Although there are many different kind of natural gas consumption in the industry this paper presents the technical and economical estimate of the injection in the blast furnace operating with coke or charcoal. The process simulation is done assisted by math modeling developed by White Martins/Praxair Inc. (author)

The core of this article is a critical analysis of different forms of pricing of natural gas existing in the world today. This paper is to describe the various scenarios of natural gas price formation models. Along the paper, the context is emphasized by considering their cases of applications and their results. Today, basically, there are three main groups of models for natural gas pricing: i) competition gas-on-gas, i.e., a liberalized natural gas market, II) gas indexed to oil prices or its products and III) bilateral monopolies and regulated prices. All the three groups of models have relevant application worldwide. Moreover, those are under dynamic influence of economic, technological and sociopolitical factors which bring complexity to the many existing scenarios. However, at first this paper builds a critical analysis of the international current situation of natural gas today and its economic relevance. (author)

Role of natural gas in meeting an electric sector emissions reduction strategy and effects on greenhouse gas emissions

International Nuclear Information System (INIS)

Lenox, Carol; Kaplan, P. Ozge

2016-01-01

With advances in natural gas extraction technologies, there is an increase in the availability of domestic natural gas, and natural gas is gaining a larger share of use as a fuel in electricity production. At the power plant, natural gas is a cleaner burning fuel than coal, but uncertainties exist in the amount of methane leakage occurring upstream in the extraction and production of natural gas. At higher leakage levels, the additional methane emissions could offset the carbon dioxide emissions reduction benefit of switching from coal to natural gas. This analysis uses the MARKAL linear optimization model to compare the carbon emissions profiles and system-wide global warming potential of the U.S. energy system over a series of model runs in which the power sector is required to meet a specific carbon dioxide reduction target across a number of scenarios in which the availability of natural gas changes. Scenarios are run with carbon dioxide emissions and a range of upstream methane emission leakage rates from natural gas production along with upstream methane and carbon dioxide emissions associated with production of coal and oil. While the system carbon dioxide emissions are reduced in most scenarios, total carbon dioxide equivalent emissions show an increase in scenarios in which natural gas prices remain low and, simultaneously, methane emissions from natural gas production are higher. - Highlights: • MARKAL analysis of energy system GHG emissions reduction scenarios. • High methane leakage can eliminate the benefit that natural gas brings over coal. • A robust GHG reduction strategy takes into account upstream emissions for all fuels.

Natural gas utilization study : offshore Newfoundland

International Nuclear Information System (INIS)

1998-10-01

A study was conducted to quantify the natural gas resources of Newfoundland and to identify production and transportation options. The objective was to create a development strategy for natural gas which is growing in global importance as an energy source and as a feedstock for the downstream industry. The growth is driven by general economic expansion and the fact that natural gas is far less polluting than its main fossil fuel alternatives of oil and coal. New use is dominated by the power generation sector. The natural gas industry is also evolving rapidly as new reserves are established and pipelines are being constructed. Proven world reserves of natural gas now stand in excess of 5000 Tcf, 70 per cent of which is in the Russian Federation (CIS) and Middle East regions. Production and consumption, however, is dominated by the industrialized countries of North America and western Europe. This difference between markets and reserves has major implications including the need to develop cost effective long-distance transportation technologies and delivery systems or to relocate downstream industries closer to the reserves. In Newfoundland, the estimated reserves total 61.9 Tcf, including 8.2 Tcf of discovered reserves and 53.7 Tcf of undiscovered reserves. Of the discovered reserves, 4.2 Tcf is on the Labrador Shelf and 4.0 Tcf is in the the Jeanne d'Arc Basin on the Grand Banks. The Hibernia development could play a major role in the development of the natural gas resources of fields within a radius of 50 km around the platform. The general conclusion from the first phase of this study is that Newfoundland's natural gas resources are valuable and potentially capable of supporting significant industrial activities. The undiscovered potential holds significant promise for both the Newfoundland offshore and onshore areas. Phase Two of the study will deal with the development and implementation of a Strategic Plan for Newfoundland's natural gas resources. A series of

This paper evaluates the production costs of a hybrid system based on a new membrane reforming MRR concept to convert natural gas to hydrogen and electricity. Membrane reforming with hydrogen-selective, palladium-silver membranes pushes the chemical equilibrium and allows higher methane conversions at lower temperature such as 650 C. The new MRR concept formed of a series of modules is put forward herein. Each module is made up of a reforming step and an external membrane separation unit. The estimates, based on utilities costs of a typical Italian refinery (end of 2006), show that the production costs for the hybrid system are 30% less than conventional tubular steam reforming technology, and 13% less than a gas-fired cogeneration plant coupled with a conventional H{sub 2} plant.

Jaber, O.; Naterer, G.F.; Dincer, I.

2010-01-01

This paper investigates various usages of natural gas (NG) as an energy source for different hydrogen production technologies. A comparison is made between the different methods of hydrogen production, based on the total amount of natural gas needed to produce a specific quantity of hydrogen, carbon dioxide emissions per mole of hydrogen produced, water requirements per mole of hydrogen produced, and a cost sensitivity analysis that takes into account the fuel cost, carbon dioxide capture cost and a carbon tax. The methods examined are the copper-chlorine (Cu-Cl) thermochemical cycle, steam methane reforming (SMR) and a modified sulfur-iodine (S-I) thermochemical cycle. Also, an integrated Cu-Cl/SMR plant is examined to show the unique advantages of modifying existing SMR plants with new hydrogen production technology. The analysis shows that the thermochemical Cu-Cl cycle out-performs the other conventional methods with respect to fuel requirements, carbon dioxide emissions and total cost of production. (author)

As low carbon-emitting fossil fuel, the natural gas is mainly used for power generation and industrial applications. It is also used for heating and cooling in commercial and residential buildings as well as in transport industry. Although the natural gas reaches the end-user mainly through pipelines (if gas is available locally), the liquefied form is the most viable alternative to transport natural gas from far away location to the end user. The economic progress in Asia and other parts of the world creates huge demand for energy (oil, gas and coal). As low carbon-emitting fuel, the demand for gas especially in liquefied form is progressively rising. Having 7th largest shale gas reserve (437 trillion cubic feet recoverable), Australia has become one of the world's major natural gas producers and exporters and is expected to continue a dominating role in the world gas market in foreseeable future. This paper reviews Australia's current gas reserve, industries, markets and LNG production capabilities.

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

Natural gas in the World 2014

International Nuclear Information System (INIS)

2014-01-01

This document summarizes the key findings of the 160-page 2014 edition of CEDIGAZ's flagship survey 'Natural Gas in the World': Worldwide proved natural gas reserves grew by 0.5% (981 bcm) in 2013. On January 1, 2014, reserves were estimated by Cedigaz to stand at 200,576 bcm, compared to 199,595 bcm for the previous year. Out of the seven regions in our regional breakdown, only North America and the C.I.S. have seen an increase in their reserves base in 2013. The strongest gain, both in absolute terms (+739 bcm) and as a percentage (+6.8%), was recorded in North America, reflecting the growth of unconventional gas reserves, both in the U.S. and Canada. The C.I.S. also posted a solid 669 bcm increase, representing a 1% rise. OPEC countries control about half of the world's gas reserves (47%) whereas C.I.S. countries account for almost one-third (33%). Proved unconventional gas reserves are concentrated in North America, especially in the U.S., which held in particular 3.7 tcm of proven shale gas reserves. Outside North America, large coal bed methane (CBM) reserves also exist in Australia and China. Marketed production was up by only 1% from 2012, reaching 3394 bcm, compared to the average growth rate for the last ten years (2.5%/year). This slowdown is partly explained by growing coal-togas competition on the demand side and a gas supply shortfall on the supply side, especially in emerging markets, where the lack of upstream investment is acute. The highest production increases were recorded in the Middle East (+3.1%) and the C.I.S. (+2.6%), which compensated for output losses in Europe (-2.3%) and Africa (-6.6%). In 2013, the two leading regional producing markets, North America and the C.I.S., accounted for 26% and 24% of global production respectively, followed by the Middle East (17%) and Asia Oceania (15%). In 2013, growth in unconventional gas production was driven by North America, China and Australia. North America no longer accounts

Short-term Canadian natural gas deliverability 2007-2009

International Nuclear Information System (INIS)

2007-01-01

This report examined factors that may influence gas supply in the near future, and presented an outlook for natural gas deliverability up to the year 2009. 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: A bridge to the future?

International Nuclear Information System (INIS)

Andriesse, C.D.

Natural gas is the cleanest fossil fuel, but never got the chance to develop its use. The reason for that is the notion that the natural gas supplies would last for only some decennia. That is only right for the conventional gas supplies. In ice crystals, some hundreds of meters deep in the oceans, enormous methane reserves, many times larger than the conventional supplies, are enclosed in so-called clathrates. From the literature it appears that other sources of natural gas or methane and new options to use these energy sources are considered or to be developed. Attention is paid to the methane reserves in geologic formations, methane produced by microbes, and methane in clathrates. It is estimated that the methane reserve is 8 x 10 2 3 Joule. By using natural gas as a fuel CO 2 emission will be reduced considerably. Methane emission however must be limited, because of the reducing effect of methane on the oxygen production in the troposphere. The large reserves of methane also offer good prospects for the production of hydrogen, large-scale applications to generate electric power or the use of CH 4 as a fuel in the transportation sector. New techniques and economic, social and institutional factors determine how fast the use of natural gas will increase. It is expected that 0.54 Tm 3 of natural gas will be needed for the twelve countries of the European Community. Main users in the year 2030 will be the electric power industry (39%), industry (26%), households and trade (18%), and transportation sector and supply (15%). In 2030 63% of natural gas has to be imported. 3 refs

Natural gas will have important position in the next decades. Nowadays, there is high demand for petrochemicals products, such as ethene and propene. With the nafta price variation, the development of alternative routes from natural gas will be stimulate, as occur in Rio de Janeiro. Between the main technologies for the natural gas use, arise the gas to liquids (GTL) routes for the conversion to hydrocarbons. Therefore, will be studied the transformation of methyl chloride to light olefins (ethene and propene) and other hydrocarbons in zeolitic catalysts. All of these reactions will be simulate occurring in the zeolitic surface, using a cluster that represents very much the catalyst structure. (author)

Greenhouse effects of the peat production and use as compared to coal, oil, natural gas and wood

1993-01-01

This report examines the greenhouse effects of greenhouse gas emissions (carbon dioxide, methane and nitrous oxide) arising from certain production and utilization chains of peat and compares them with the corresponding effects associated with the production and utilization chains of coal, oil, natural gas and wood. In order to estimate the greenhouse effects of the peat production and utilization chains, the initial state of the peat bog together with the instantaneous and cumulative greenhouse effects associated with the production and burning of peat as well as subsequent use of the production area were taken into account. The initial state of the peat bog was taken to be either a bog in its natural sale, a forest-drained bog or a cultivated peatland. As regards alternatives for subsequent use of the peat production area, afforestation, paludification and lake formation were all examined

Highlights: • Solar energy integrated with natural-gas-to-methanol process is proposed. • The two processes are modeled and simulated. • Performance analysis of the two processes are conducted. • The proposed process can cut down the greenhouse gas emission. • The proposed process can save natural gas consumption. - Abstract: Methanol is an important platform chemical. Methanol production using natural gas as raw material has short processing route and well developed equipment and technology. However, natural gas reserves are not large in China. Solar energy power generation system integrated with natural-gas-to-methanol (NGTM) process is developed, which may provide a technical routine for methanol production in the future. The solar energy power generation produces electricity for reforming unit and system consumption in solar energy integrated natural-gas-to-methanol system (SGTM). Performance analysis of conventional natural-gas-to-methanol process and solar energy integrated with natural-gas-to-methanol process are presented based on simulation results. Performance analysis was conducted considering carbon efficiency, production cost, solar energy price, natural gas price, and carbon tax. Results indicate that solar energy integrated with natural-gas-to-methanol process is able to cut down the greenhouse gas (GHG) emission. In addition, solar energy can replace natural gas as fuel. This can reduce the consumption of natural gas, which equals to 9.2% of the total consumed natural gas. However, it is not economical considering the current technology readiness level, compared with conventional natural-gas-to-methanol process.

Coal and lignite will play a significant role in the future energy production. However, the technical options for the reduction of CO 2 emissions will define the extent of their share in the future energy mix. The production of synthetic or substitute natural gas (SNG) from solid fossil fuels seems to be a very attractive process: coal and lignite can be upgraded into a methane rich gas which can be transported and further used in high efficient power systems coupled with CO 2 sequestration technologies. The aim of this paper is to present a modeling analysis comparison between substitute natural gas production from coal by means of allothermal steam gasification and autothermal oxygen gasification. In order to produce SNG from syngas several unit operations are required such as syngas cooling, cleaning, potential compression and, of course, methanation reactors. Finally the gas which is produced has to be conditioned i.e. removal of unwanted species, such as CO 2 etc. The heat recovered from the overall process is utilized by a steam cycle, producing power. These processes were modeled with the computer software IPSEpro™. An energetic and exergetic analysis of the coal to SNG processes have been realized and compared. -- Highlights: ► The production of SNG from coal is examined. ► The components of the process were simulated for integrated autothermal or allothermal coal gasification to SNG. ► The energetic and exergetic evaluation of the two processes is presented.

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

Natural gas markets in the Pacific Rim

International Nuclear Information System (INIS)

Hertzmark, D.I.

1991-01-01

In the 1980s, Asian energy markets expanded at a rapid rate to meet the surge in demand from Japan, South Korea, and Taiwan. This demand boom coincided with an increase in non-OPEC oil production in the region. As oil production stabilizes, demand appears to be surging again, but this time in the Southeast Asian countries. Natural gas will play a key role in this expansion of energy use and could start to lead rather than follow the oil market. This will be especially true as compressed natural gas and oxygenates start to take significant shares of the transportation fuel markets, while the role of residual fuel oil is increasingly usurped by gas for environmental reasons. Many new gas sources such as Papua New Guinea, Siberia, China, and Canada will fight for market share while domestic demand in Indonesia and Malaysia takes up increasing proportions of those countries' gas production. Extensive regional transportation schemes are likely to direct more of the gas output of Southeast Asia to intra-ASEAN uses. 2 tabs

1989-01-01

The Gas Analysis Modeling System is a large computer-based model for analyzing the complex US natural gas industry, including production, transportation, and consumption activities. The model was developed and first used in 1982 after the passage of the NGPA, which initiated a phased decontrol of most natural gas prices at the wellhead. The categorization of gas under the NGPA and the contractual nature of the natural gas market, which existed at the time, were primary factors in the development of the basic structure of the model. As laws and regulations concerning the natural gas market have changed, the model has evolved accordingly. Recent increases in competition in the wellhead market have also led to changes in the model. GAMS produces forecasts of natural gas production, consumption, and prices annually through 2010. It is an engineering-economic model that incorporates several different mathematical structures in order to represent the interaction of the key groups involved in the natural gas market. GAMS has separate supply and demand components that are equilibrated for each year of the forecast by means of a detailed transaction network

Density functional theory was performed for thermodynamic predictions on natural gas, whose B3LYP/6-311++G(d,p), B3LYP/6-31+G(d), CBS-QB3, G3, and G4 methods were applied. Additionally, we carried out thermodynamic predictions using G3/G4 averaged. The calculations were performed for each major component of seven kinds of natural gas and to their respective air + natural gas mixtures at a thermal equilibrium between room temperature and the initial temperature of a combustion chamber during the injection stage. The following thermodynamic properties were obtained: internal energy, enthalpy, Gibbs free energy and entropy, which enabled us to investigate the thermal resistance of fuels. Also, we estimated an important parameter, namely, the specific heat ratio of each natural gas; this allowed us to compare the results with the empirical functions of these parameters, where the B3LYP/6-311++G(d,p) and G3/G4 methods showed better agreements. In addition, relevant information on the thermal and mechanic resistance of natural gases were investigated, as well as the standard thermodynamic properties for the combustion of natural gas. Thus, we show that density functional theory can be useful for predicting the thermodynamic properties of natural gas, enabling the production of more efficient compositions for the investigated fuels.

Henry, D.

2005-01-01

The impact of rising natural gas prices on the United States economy and domestic industries was examined in this PowerPoint presentation. Industry comments were solicited on the effects of natural gas prices on their business performance from 2000 to 2004 in order to collect data, and macroeconomic impacts were determined through the use of an inter-industry model. Results of the survey and subsequent model suggested that in 2000 and 2001, real gross domestic product (GDP) growth was depressed by 0.2 per cent because of higher natural gas prices. Between 2000 and 2004, the civilian workforce was lower by 489,000 jobs. It was determined that nitrogenous fertilizer manufacturing was the most gas intensive industry. The results indicated that higher natural gas prices were an additional burden on manufacturing industries, and that the economic performance of natural gas intensive industries was poor between 2000-2004. However, it was just as poor between 1997-2000, when gas prices were relatively low and stable. Natural gas intensive industries passed along price increases in their products to their downstream consumers. Despite job losses, wages in natural gas intensive industries were higher and grew faster than in the rest of the manufacturing industry in the 2000-2004 period. Although capital expenditures declined between 2000 to 2004, they declined more rapidly in the 1997-2000 period. There has been no evidence of a decline in international competitiveness of natural gas intensive industries. It was concluded that rising natural gas prices have had a significant impact on the growth of the economy and workforce. tabs., figs

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

1995-01-01

This paper examines the potential profitability of a selected group of possible natural gas conversion processes from the perspective of a manufacturing entity that has access to substantial low cost natural gas reserves, capital to invest, and no allegiance to any particular product. The analysis uses the revenues and costs of conventional methanol technology as a framework to evaluate the economics of the alternative technologies. Capital requirements and the potential to enhance cash margins are the primary focus of the analysis. The basis of the analysis is a world-scale conventional methanol plant that converts 3.2 Mm 3 per day (120 MMSCFD) of natural gas into 3510 metric tonnes (3869 shorts tons) per day of methanol. Capital and operating costs are for an arbitrary remote location where natural gas is available at 0.47 US dollars per GJ (0.50 US dollars per MMBtu). Other costs include ocean freight to deliver the product to market at a US Gulf Coast location. Payout time, which is the ratio of the total capital investment to cash margin (revenue less total operating expenses), is the economic indicator for the analysis. Under these conditions, the payout time for the methanol plant is seven years. The payout time for the alternative natural gas conversion technologies is generally much higher, which indicates that they currently are not candidates for commercialization without consideration of special incentives. The analysis also includes an evaluation of the effects of process yields on the economics of two potential technologies, oxidative coupling to ethylene and direct conversion to methanol. This analysis suggests areas for research focus that might improve the profitability of natural gas conversion. 29 refs., 14 figs., 5 tabs

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.

Tapping methane hydrates for unconventional natural gas

Science.gov (United States)

Ruppel, Carolyn

2007-01-01

Methane hydrate is an icelike form of concentrated methane and water found in the sediments of permafrost regions and marine continental margins at depths far shallower than conventional oil and gas. Despite their relative accessibility and widespread occurrence, methane hydrates have never been tapped to meet increasing global energy demands. With rising natural gas prices, production from these unconventional gas deposits is becoming economically viable, particularly in permafrost areas already being exploited for conventional oil and gas. This article provides an overview of gas hydrate occurrence, resource assessment, exploration, production technologies, renewability, and future challenges.

Highlights: • Design of iron-based chemical looping process using moving bed for H_2 from CH_4. • Auto-thermal operation design using thermodynamic rationale for 90% carbon capture. • Cold gas efficiency: 5% points higher than Steam Methane Reforming baseline case. • Net thermal efficiency: 6% points higher than Steam Methane Reforming baseline case. • Sensitivity analysis: Energy recovery scheme, operating pressure, no carbon capture. - Abstract: Hydrogen (H_2) is a secondary fuel derived from natural gas. Currently, H_2 serves as an important component in refining operations, fertilizer production, and is experiencing increased utilization in the transportation industry as a clean combustion fuel. In recent years, industry and academia have focused on developing technology that reduces carbon emissions. As a result, there has been an increase in the technological developments for producing H_2 from natural gas. These technologies aim to minimize the cost increment associated with clean energy production. The natural gas processing chemical looping technology, developed at The Ohio State University (OSU), employs an iron-based oxygen carrier and a novel gas–solid counter-current moving bed reactor for H_2 production. Specifically, this study examines the theoretical thermodynamic limits for full conversion of natural gas through iron-based oxygen carrier reactions with methane (CH_4), by utilizing simulations generated with ASPEN modeling software. This study initially investigates the reducer and the oxidizer thermodynamic phase diagrams then derives an optimal auto-thermal operating condition for the complete loop simulation. This complete loop simulation is initially normalized for analysis on the basis of one mole of carbon input from natural gas. The H_2 production rate is then scaled to match that of the baseline study, using a full-scale ASPEN simulation for computing cooling loads, water requirements and net parasitic energy consumption.

The purpose of the present work is to formulate and evaluate a mathematical model inherent to the process to produce H{sub 2} in Venezuela through reforming natural gas and removing carbon dioxide (CO{sub 2}). The aim of this work is to identify opportunities to recover gas released through the air and from burning natural gas which, in turn, makes it possible to mitigate the effects of global warming. The development of the mathematical model is linear, and includes the production of H{sub 2} the efficiency of the energy conversion process, the cost of the main inputs and resources (natural gas, water and electricity), the cost of reforming and the CO{sub 2} capture system, transport and storage. Three scenarios were considered for the sustainable production of H{sub 2} conventional hydrogen production, H{sub 2} production with direct CO{sub 2} removal, and the production of H{sub 2} with CO{sub 2} removal and increased natural gas from depleted wells (EGR). The results indicate that in Venezuela, more than 1 million tons of hydrogen per year can be produced at a low cost of 1 $/K, with a CO{sub 2} removal effectiveness over 61% and an EGR factor of roughly 8%. In addition, a significant reduction in gas released into the atmosphere would prevent the yearly injection of more than 23 million tons of CO{sub 2} (11,7% of total national CO{sub 2}). The total production cost obtained is significantly lower than that mentioned in the literature, including the target cost by 2017 expected by the U.S. Department of Energy (DOE). [Spanish] El proposito del presente trabajo consiste en la formulacion y evaluacion de un modelo matematico inherente al proceso de produccion de H{sub 2} en Venezuela, mediante el reformado del gas natural y la remocion del dioxido de carbono (CO{sub 2}); con la finalidad de identificar oportunidades para la recuperacion de gas arrojado (venteo y quemado de gas natural) que a su vez permitan mitigar los efectos de calentamiento global.

Does Increased Extraction of Natural Gas Reduce Carbon Emissions?

Aune, F.R.; Golombek, R.; Kittelsen, S.A. C.

2004-01-01

Without an international climate agreement, extraction of more natural gas could reduce emissions of CO2 as more 'clean' natural gas may drive out ''dirty'' coal and oil. Using a computable equilibrium model for the Western European electricity and natural gas markets, we examine whether increased extraction of natural gas in Norway reduces global emissions of CO2. We find that both in the short run and in the long run total emissions are reduced if the additional quantity of natural gas is used in gas power production in Norway. If instead the additional quantity is exported directly, total emissions increase both in the short run and in the long run. However, if modest CO2-taxes are imposed, increased extraction of natural gas will reduce CO2 emissions also when the additional natural gas is exported directed

Out of gas: Tenneco in the era of natural gas regulation, 1938--1978

Science.gov (United States)

Raley, David

2011-12-01

Federal regulation over the natural gas industry spanned 1938--1978, during which time both the industry and the nature of the regulation changed. The original intent of the law was to reform an industry stagnating because of the Depression, but regulation soon evolved into a public-private partnership to win World War II, then to a framework for the creation and management of a nationwide natural gas grid in the prosperous post-war years, and finally to a confused and chaotic system of wellhead price regulation which produced shortages and discouraged new production during the 1950s and 1960s. By the 1970s, regulation had become ineffective, leading to deregulation in 1978. The natural gas industry operated under the oversight of the Federal Power Commission (FPC) which set gas rates, regulated profits and competition, and established rules for entry and exit into markets. Over the course of four decades, the FPC oversaw the development of a truly national industry built around a system of large diameter pipelines. Tennessee Gas Transmission Company (later Tenneco) was an integral part of this industry. At first, Tenneco prospered under regulation. Regulation provided Tenneco with the means to build its first pipeline and a secure revenue stream for decades. A series of conflicts with the FPC and the difficulties imposed by the Phillips vs. Wisconsin case in 1954 soon interfered with the ambitious long-term goals of Tenneco CEO and president Gardiner Symonds. Tenneco first diversified into unregulated businesses in the 1940s, which accelerated as regulatory changes constrained the company's growth. By the 1960s the company was at the forefront of the conglomeration movement, when Tenneco included a variety of disparate businesses, including oil and gas production, chemicals, consumer packaging, manufacturing, shipbuilding, and food production, among others. Gas transmission became a minority interest in Tenneco's portfolio as newer and larger divisions

Industrial development based on natural gas has broad, industrial implications. Norway has a vital industry based on natural gas as raw material, here under Ormen Lange, Snoehvit LNG, Tjeldbergodden and Petrochemical Grenland. The petrochemical industry has challenges, e.g. the cost of raw materials and energy, localization related to the markets, and recruitment, but considerable investments are made in the sector. The Northern areas in Norway may have special challenges related to bringing the product to the market. Solutions to this challenge are in LNG (liquid natural gas), GTL (gas to liquids), and GTO (gas to olefins)

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

2013 - The Natural Gas Year in Review

International Nuclear Information System (INIS)

Lecarpentier, Armelle

2014-01-01

Natural gas consumption only rose by 1.3%, down from an average growth of 2.8% per year in the previous decade. Natural gas still suffers in particular from severe competition with coal in the power generation sector. Inside the EU-28, actual consumption was estimated down 1.9% to 460 Billion cubic metres (Bcm). This poor performance brought European consumption to levels not seen in more than 15 years. In the US, rising gas prices compared to 2012 has often made coal more competitive and penalized gas consumption in the power generation sector, causing it to fall by 10.5%. Global growth in natural gas has been increasingly constrained by supply. In 2013, the growth in gas production slowed substantially to 0.8%, bringing the total volume to 3377 Bcm. As before, the gas supply shortfall was due to the decline of mature and conventional fields, and an insufficient renewal of reserves. The lack of upstream investment is especially acute in emerging markets, due to a lack of a favourable regulatory and fiscal climate. The moderation of natural gas supply and investment has also been increasingly driven by geopolitical challenges. Deterioration of security, internal conflicts and resulting damage to infrastructures have caused some production outages and supply disruptions in some countries. In 2013, marketed production fell especially heavily in Africa (Algeria, Nigeria, Libya and Egypt). With the exception of Europe, other regions posted positive production gains. The largest of them were recorded in the CIS (+ 2.7%) and the Middle East (+ 3.4%). International gas trade increased significantly by 2.1% to 1048 Bcm, due to the growing dependence of consumer markets on increasingly distant production sources, sometimes located in economically and politically unstable areas. The rise in the international gas trade was only driven by inter-regional pipeline gas exports from the CIS to Europe (+ 15%) and China (+ 36%). Geopolitical risks are having an ever

Domestic natural gas production was largely stagnant from the mid-1970s until about 2005. However, beginning in the late 1990s, advances linking horizontal drilling techniques with hydraulic fracturing allowed drilling to proceed in shale and other formations at much lower cost. The result was a slow, steady increase in unconventional gas production. The Joint Institute for Strategic Energy Analysis (JISEA) designed this study to address four related key questions, which are a subset from the wider dialogue on natural gas; regarding the life cycle greenhouse gas (GHG) emissions associated with shale gas compared to conventional natural gas and other fuels used to generate electricity; existing legal and regulatory frameworks governing unconventional gas development at federal, state, and local levels, and changes in response to the rapid industry growth and public concerns; natural gas production companies changing their water-related practices; and demand for natural gas in the electric sector.

2005-01-01

One of the difficulties associated with the development of a hydrogen economy is the creation of a supply infrastructure. A means for distributed hydrogen generation through a process using the exergy in high pressure natural gas streams has been proposed. The system recovers energy via expansion of natural gas through a turbo-expander at existing pressure reduction systems. Generated electric power is then used to drive an electrolyzer and create hydrogen. A model of the process is used to determine production rates for electricity and hydrogen given flow data for a number of pressure letdown sites in BC. Like many traditional renewable energy sources, most letdown stations have strong annual variations in flow conditions. Annual variations in stream flow rate, inlet pressure and inlet temperature can greatly affect hydrogen production rates. In the model, component efficiencies are scaled for operation at part-load, or away from optimum design conditions. Results indicate a significant reduction in predicted hydrogen production rates as compared to installed component name-plate capacity. Operating the system with a 'grid-tie' can increase the capacity factor, but economic viability will depend on local electricity and natural gas prices. (author)

Alternative ways to transport natural gas; Transporte alternativo de gas natural

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)

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

International Nuclear Information System (INIS)

Coconea, G.

1993-01-01

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

Natural gas is being considered as an important transition fuel in an integrated national strategy to reduce emissions of greenhouse gases in the United States due to its lower carbon dioxide (CO 2 ) emission per unit of energy produced. However, the contribution of atmospheric methane (CH 4 ) from the production and handling of natural gas must also be considered. Radian Corporation has been working with the Gas Research Institute and the US Environmental Protection Agency to detail the sources of methane from the natural gas industry in the United States. All aspects of natural gas production, processing, transmission, storage and distribution are being examined. Preliminary results of preliminary testing for the below-ground gas distribution industry segment are presented. The emission rate (scf/hr) is the product of the leak rate per unit length of underground pipe and the total length of US distribution system pipelines. Preliminary estimates for the below-ground distribution segment are nearly 9 billion scf/yr. This total likely underestimates below-ground methane emissions for several reasons. These preliminary analyses suggest that significant uncertainty surround current methane emission estimates from below-ground distribution systems. Emission estimates from all segments of the US Natural Gas Industry, broken down by fugitive sources and non-fugitive sources, are also presented. The specific test methods being implemented to quantify emissions from each segment are described

Natural gas to start long period of growth during next 3 years

Pressures are building worldwide to increase consumption of natural gas. During the past decade, worldwide marketed production of natural gas has moved up much faster than oil and coal production. Gas output increased from 51.8 tcf in 1982 to 72.1 tcf in 1992. This 39.2% production increase compares with gains of 13.7% for oil and 15.2% for coal. The natural gas share of worldwide energy consumption moved up from 20.1% in 1982 to 22.8% in 1992. The biggest change was in the C.I.S. and East Europe, where the gas share of total energy use rose from 28.8% in 1982 to 41.3% in 1992. In the OECD, the gas share of total energy use rose from 21.1% in 1982 to 21.5% in 1992. The natural gas industry was well-developed by 1982 in many industrial countries. In the developing world, gas provided 10.4% of total energy in 1982 and 12.5% in 1992. The paper discusses production trends, gas trade trends, natural gas prices, gas reserves, drilling shifts, and the demand outlook

Canadian natural gas market dynamics and pricing : an update

International Nuclear Information System (INIS)

2002-10-01

This energy market assessment (EMA) report discusses natural gas price formation and describes the current functioning of regional gas markets in Canada. This EMA also describes the factors affecting the price of natural gas in Canada and examines natural gas markets on a region-by region basis. It is shown that as part of an integrated North American market, prices of natural gas in Canada reflect supply and demand factors in both Canada and the United States. During the low oil price period of 1997/1998, high demand for natural gas outpaced the supply because of low drilling and production activity by producers. In response to the increased demand and lower levels of supply, the price of natural gas increased significantly in 1999 and 2000. This was followed by a period of market adjustment. The importance of electronic trading systems for enhancing price discovery was also discussed with reference to how spot and futures markets allow market participants to manage price volatility. It was determined that Canadians have had access to natural gas on terms and conditions equal to export customers, and at equal pricing. In early November 2000, natural gas prices in North American began to rise due to low levels of natural gas in storage. The price shocks were felt unevenly across the North American market. In response to the high prices, consumers conserved energy use, and many industrial users switched to cheaper fuels. By the spring 2001, demand continued to decrease at a time when production was high. These factors contributed to the downward pressure on gas prices. This EMA discusses the structure of market transactions and market adjustment mechanisms. It is presented in the context of the approaching 2002/2003 winter season where the tightening between natural gas supply and demand is expected to result in price volatility. 28 figs

Natural gas in Latin America

International Nuclear Information System (INIS)

1997-01-01

Despite having proven reserves equal to that of North America, natural gas has traditionally played a minor role in the energy policies of Latin American countries, being considered secondary to oil. There has, therefore, been a neglect of the sector with a resultant lack of an adequate infrastructure throughout the region, perhaps with the exception of Argentina. However, with a massive increase in energy demand, growing concerns with environmental matters and a need to reduce the massive pollution levels in major cities in the region, natural gas is forecast to play a much greater role in Latin America's energy profile, with final consumption forecast to rise at 5.4% per annum for the next 15 years. This book assesses both the development of the use of natural gas in the power industrial sector and proposals for its growth into the residential, commercial and transport sectors. It analyses the significant investment required and the governments' need to turn to the private sector for investment and innovation. Natural Gas in Latin America analyses the possibilities and pitfalls of investing in the sector and describes the key trends and issues. It analyses all aspects of the gas industry from exploration and production to transportation and distribution to end users. (Author)

The invention concerns an method and system for offshore production of liquefied natural gas (LNG), wherein natural gas is supplied from an underground source to a subsea production plant. The gas is transferred under a high pressure directly from the production plant to an LNG tanker through a pipeline underwater causing the temperature of the high pressure gas to be lowered to a desired low temperature. This gas is supplied to a conversion plant provided on the LNG tanker and arranged for converting at least a part of the gas to liquid form, and the liquefied gas is transferred to storage tanks on board the same. When the storage tanks are filled up, the pipeline is disconnected from the LNG tanker and connected to another similar tanker. The pipeline is permanently connected to a submerged buoy which is arranged for introduction and releasable securement in a submerged downwardly open receiving space in the tanker, and which is provided with a swivel unit for transfer of gas under a high pressure. 3 figs.

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

1992-01-01

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

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.

Formation rate of natural gas hydrate

Energy Technology Data Exchange (ETDEWEB)

Mork, Marit

2002-07-01

The rate of methane hydrate and natural gas hydrate formation was measured in a 9.5 litre stirred tank reactor of standard design. The experiments were performed to better understand the performance and scale-up of a reactor for continuous production of natural gas hydrates. The hydrate formation rate was measured at steady-state conditions at pressures between 70 and 90 bar and temperatures between 7 and 15 deg C. Between 44 and 56 % of the gas continuously supplied to the reactor was converted to hydrate. The experimental results show that the rate of hydrate formation is strongly influenced by gas injection rate and pressure. The effect of stirring rate is less significant and subcooling has no observable effect on the formation rate. Hydrate crystal concentration and gas composition do not influence the hydrate formation rate. Observations of produced hydrate crystals indicate that the crystals are elongated, about 5 micron in diameter and 10 micron long. Analysis of the results shows that the rate of hydrate formation is dominated by gas-liquid mass transfer. A mass transfer model, the bubble-to-crystal model, was developed for the hydrate formation rate in a continuous stirred tank reactor, given in terms of concentration driving force and an overall mass transfer coefficient. The driving force is the difference between the gas concentration at the gas-liquid interface and at the hydrate crystal surface. These concentrations correspond to the solubility of gas in water at experimental temperature and pressure and the solubility of gas at hydrate equilibrium temperature and experimental pressure, respectively. The overall mass transfer coefficient is expressed in terms of superficial gas velocity and impeller power consumption, parameters commonly used in study of stirred tank reactors. Experiments and modeling show that the stirred tank reactor has a considerable potential for increased production capacity. However, at higher hydrate production rates the

The Brazilian Federal Government has the very purpose of increasing the participation of the Natural Gas in the primary energy internal supply from 7,5% nowadays to about 12% till 2010. However, for that, it is necessary to eliminate the great impedance represented by the restricted accessibility to the product, due to the high distribution costs involved. So, there is an urgent need for availability of technologies to help natural gas distribution systems. This paper proposes an innovative logistics-based approach on the subject of the natural gas distribution, through a computational tool (GASLOG System) to be applied in the North and Northeastern urban and country areas of Brazil, with initial case study in the city of Fortaleza. In its conception, the GASLOG System focuses on the point-of-view of everyone of the actors involved with the natural gas distribution process trying to respond their particular necessities in the sector.

Characterizing the emission implications of future natural gas production and use in the U.S. and Rocky Mountain region: A scenario-based energy system modeling approach

Science.gov (United States)

McLeod, Jeffrey

The recent increase in U.S. natural gas production made possible through advancements in extraction techniques including hydraulic fracturing has transformed the U.S. energy supply landscape while raising questions regarding the balance of environmental impacts associated with natural gas production and use. Impact areas at issue include emissions of methane and criteria pollutants from natural gas production, alongside changes in emissions from increased use of natural gas in place of coal for electricity generation. In the Rocky Mountain region, these impact areas have been subject to additional scrutiny due to the high level of regional oil and gas production activity and concerns over its links to air quality. Here, the MARKAL (MArket ALlocation) least-cost energy system optimization model in conjunction with the EPA-MARKAL nine-region database has been used to characterize future regional and national emissions of CO 2, CH4, VOC, and NOx attributed to natural gas production and use in several sectors of the economy. The analysis is informed by comparing and contrasting a base case, business-as-usual scenario with scenarios featuring variations in future natural gas supply characteristics, constraints affecting the electricity generation mix, carbon emission reduction strategies and increased demand for natural gas in the transportation sector. Emission trends and their associated sensitivities are identified and contrasted between the Rocky Mountain region and the U.S. as a whole. The modeling results of this study illustrate the resilience of the short term greenhouse gas emission benefits associated with fuel switching from coal to gas in the electric sector, but also call attention to the long term implications of increasing natural gas production and use for emissions of methane and VOCs, especially in the Rocky Mountain region. This analysis can help to inform the broader discussion of the potential environmental impacts of future natural gas production

2003-11-01

This annual working paper was prepared to provide summaries of North American natural gas industry trends. It also reviews Canadian gas exports. It should be noted that the Mexican market was largely excluded from this report. The objective is to foster dialogue between government and industry to obtain feedback concerning natural gas issues. In the main section of the report, graphs were provided along with limited text comments, proposing a structured look at market fundamentals (supply and demand) over 2002, for the near term (2003 and early 2004), as well as the long term to 2015. Private consultants, industry associations, and federal government agencies in both Canada and the United States provided information that was used for preparing this report. A very mild 2001/2002 winter resulted in low demand for natural gas in the beginning of 2002. The market seemed to recognize that natural gas wells in North America were flowing at essentially full capacity. The core markets included residential and commercial demand. Storage levels and the weather are the two factors most likely to drive natural gas prices through the end of the winter of 2003/2004. Natural gas production growth and world crude oil prices are also expected to play an important role. On April 1, 2003, storage levels in North America were low, and industry was back on track by September 1, 2003 due to injections into storage during the summer. Natural gas demand in North America is expected to increase in the long term, fuelled by increased demand by industrial and electric power generation. North American production forecasts were revised downwards, compared to last year's report. The Canadian supply forecasts did not include Canadian imports of liquid natural gas or Newfoundland natural gas production. 25 refs., 16 tabs., 55 figs

Electricity/natural gas competition in Quebec

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

Mercury Removal from Natural Gas in Egypt

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

Canadian natural gas : review of 2007/08 and outlook to 2020

International Nuclear Information System (INIS)

2008-12-01

This report discussed natural gas industry trends in Canada and the United States. An overview of the current state of the North American natural gas market was provided in addition to a historical record of 2007. Recent natural gas market dynamics related to supply and demand were evaluated using statistical data from the National Energy Board (NEB); the United States Energy Information Administration (EIA); and Statistics Canada. Natural gas consumed by oil sands producers represented 412 billion cubic feet. The data indicated that major changes are now occurring in the North American gas market. While Canadian gas production has declined, unconventional gas development will result in higher Canadian production levels. Producers are now paying higher prices for shale prospective land in British Columbia (BC). Natural gas prices have dropped significantly as a result of the volatility of crude oil prices. North American storage volumes have also fallen from 3.5 Tcf to 3.3 Tcf. Net exports in 2007 represented 56 per cent of the total gas produced in Canada. Liquefied natural gas (LNG) supplies will moderate the price of natural gas in the future. It was concluded that new regulation and policies must not impede the sustainable development of natural gas supplies. 12 refs., 5 tabs., 32 figs

Methane hydrates and the future of natural gas

Science.gov (United States)

Ruppel, Carolyn

2011-01-01

For decades, gas hydrates have been discussed as a potential resource, particularly for countries with limited access to conventional hydrocarbons or a strategic interest in establishing alternative, unconventional gas reserves. Methane has never been produced from gas hydrates at a commercial scale and, barring major changes in the economics of natural gas supply and demand, commercial production at a large scale is considered unlikely to commence within the next 15 years. Given the overall uncertainty still associated with gas hydrates as a potential resource, they have not been included in the EPPA model in MITEI’s Future of Natural Gas report. Still, gas hydrates remain a potentially large methane resource and must necessarily be included in any consideration of the natural gas supply beyond two decades from now.

Thermochemical Equilibrium Model of Synthetic Natural Gas Production from Coal Gasification Using Aspen Plus

Directory of Open Access Journals (Sweden)

Rolando Barrera

2014-01-01

Full Text Available The production of synthetic or substitute natural gas (SNG from coal is a process of interest in Colombia where the reserves-to-production ratio (R/P for natural gas is expected to be between 7 and 10 years, while the R/P for coal is forecasted to be around 90 years. In this work, the process to produce SNG by means of coal-entrained flow gasifiers is modeled under thermochemical equilibrium with the Gibbs free energy approach. The model was developed using a complete and comprehensive Aspen Plus model. Two typical technologies used in entrained flow gasifiers such as coal dry and coal slurry are modeled and simulated. Emphasis is put on interactions between the fuel feeding technology and selected energy output parameters of coal-SNG process, that is, energy efficiencies, power, and SNG quality. It was found that coal rank does not significantly affect energy indicators such as cold gas, process, and global efficiencies. However, feeding technology clearly has an effect on the process due to the gasifying agent. Simulations results are compared against available technical data with good accuracy. Thus, the proposed model is considered as a versatile and useful computational tool to study and optimize the coal to SNG process.

Highlights: • A novel coal and coke-oven gas to SNG (CGtSNG) process is proposed. • Energy efficiency of CGtSNG increases 8% compared to coal-to-SNG process. • CGtSNG reduces 60% CO_2 emission and 72% effluent discharge. • CGtSNG proposes an idea of using redundant coke-oven gas for producing SNG production. - Abstract: There was a rapid development of coal to synthetic natural gas (SNG) projects in the last few years in China. The research from our previous work and some other researchers have found coal based SNG production process has the problems of environmental pollution and emission transfer, including CO_2 emission, effluent discharge, and high energy consumption. This paper proposes a novel co-feed process of coal and coke-oven gas to SNG process by using a dry methane reforming unit to reduce CO_2 emissions, more hydrogen elements are introduced to improve resource efficiency. It is shown that the energy efficiency of the co-feed process increases by 4%, CO_2 emission and effluent discharge is reduced by 60% and 72%, whereas the production cost decreases by 16.7%, in comparison to the conventional coal to SNG process. As coke-oven gas is a waste gas in most of the coking plant, this process also allows to optimize the allocation of resources.

'Natural Gas lift', a New Tool for Nigeria

International Nuclear Information System (INIS)

Lucas, C. D.

2003-01-01

Gas lift is the most common means of artificial lift in the Niger Delta and has been widely applied worldwide. The advent of remote monitoring and control devises (RMC) has added a new option in artificiallift, 'natural gas lift'. 'Natural gas lift' is an extension RMC in which a gas zone and one or more oil zones are produced through the same tubing string, using the gas enhance the production of the oil zones. The flow of gas is maintained in the optimal range using down hole chokes that are controlled from the surface. The gas flow rate is monitored using downhole pressure and .temperature gauges. The use of 'natural gas lift' has the advantages of gas lift but without the cost associated with gas lift; gas supply wells, compression etc. This is especially critical in areas that are remote from other facilities or in subsea completions where access to the wells is limited. Stacked reservoirs and frequent inclusion of both oil and gas reservoirs in the same field, as found in the Niger Delta, makes Nigeria a prime candidate for this technology. An example of this production from the North Sea will be presented along with a potential application using data from the Niger Delta. Design elements of the monitoring and control systems will be covered and the advantages and drawbacks of this application will be discussed

The economics of natural gas

International Nuclear Information System (INIS)

Julius, D.; Mashayekhi, A.

1990-01-01

Natural gas resembles oil in fulfilling a wide variety of uses as both a source of energy and a feedstock, but the proportion of world production that is traded internationally is very much lower, and insufficient for a world price of gas to be established. Written specifically for economists interested in energy, development and industrial economics; oil and gas industry personnel; officials of developing countries; and intergovernmental organizations concerned with development. This book addresses the issues of how the economic price of gas is determined within individual countries with different characteristics and which factors should be taken into account by governments in the formulation of pricing policies that are appropriate for gas. These are illustrated with estimates of the costs of exploration and production of gas, and of the benefits to be derived from its use in various economic sectors for a number of Third World countries. The book also presents a detailed case study of the development of gas pricing in Bangladesh, and an analytical framework for the development of a formal gas planning model that could be applied to the cases of actual countries contemplating the development of gas use in the future

Venezuela natural gas outlook

International Nuclear Information System (INIS)

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

Low Carbon Technology Options for the Natural Gas ...

The ultimate goal of this task is to perform environmental and economic analysis of natural gas based power production technologies (different routes) to investigate and evaluate strategies for reducing emissions from the power sector. It is a broad research area. Initially, the research will be focused on the preliminary analyses of hydrogen fuel based power production technologies utilizing hydrogen fuel in a large size, heavy-duty gas turbines in integrated reformer combined cycle (IRCC) and integrated gasification combined cycle (IGCC) for electric power generation. The research will be expanded step-by-step to include other advanced (e.g., Net Power, a potentially transformative technology utilizing a high efficiency CO2 conversion cycle (Allam cycle), and chemical looping etc.) pre-combustion and post-combustion technologies applied to natural gas, other fossil fuels (coal and heavy oil) and biomass/biofuel based on findings. Screening analysis is already under development and data for the analysis is being processed. The immediate action on this task include preliminary economic and environmental analysis of power production technologies applied to natural gas. Data for catalytic reforming technology to produce hydrogen from natural gas is being collected and compiled on Microsoft Excel. The model will be expanded for exploring and comparing various technologies scenarios to meet our goal. The primary focus of this study is to: 1) understand the chemic

The opening of the Brazilian economy and the end of the state-owned oil company PETROBRAS monopoly made possible for national and international companies to become concessionaires of the rights and obligations regarding the exploration, development and production of oil and natural gas. The increasing of the oil reserves and production, together with the technological development and the more restricted environmental legislation, resulted in a gradual increased participation of the natural gas in the Brazilian domestic energy supply. Around 3% for many years, the participation of gas in the Brazilian domestic energy supply has increased to 7.5% in 2002, as mentioned in the 2003 Brazil Energy Balance (BEN). The 2003 production was more than 100 millions boe, and the import was more than 37 millions boe according to the National Oil Agency (ANP).

Helium production technology based on natural gas combustion and beneficial use of thermal energy

Directory of Open Access Journals (Sweden)

Nakoryakov Vladimir E.

2016-01-01

Full Text Available Helium is widely used in all industries, including power plant engineering. In recent years, helium is used in plants operating by the Brayton cycle, for example, in the nuclear industry. Using helium-xenon mixture in nuclear reactors has a number of advantages, and this area is rapidly developing. The hydrodynamics and mass transfer processes in single tubes with various cross-sections as well as in inter-channel space of heating tube bundle were studied at the Institute of Thermophysics, Siberian Branch of the Russian Academy of Sciences. Currently, there is a strongest shortage in helium production. The main helium production method consists in the liquefaction of the natural gas and subsequent separation of helium from remaining gas with its further purification using membranes.

OPEC and natural gas

This paper reviews the involvement of OPEC Member Countries in the natural gas industry in the past, present and future. It notes a tenfold increase in marketed production and a fourfold rise in re-injection since 1970. Collectively, Members now hold 41 per cent of the world's proven gas reserves and account for 20 per cent of exports. Individually, four of these countries hold position 2-5 in the world gas reserve rankings. Within OPEC, however, there remains an emphasis of oil over gas, not least because of oil's favourable position with regard to revenue-generation and profitability. As global demand continues on its upward growth curve in a more environmentally aware world, OPEC's gas horizons will widen. OPEC's strong reserve base will give its Members an undeniable role to play on the future global gas stage. However, these countries will give priority to domestic usage, particularly re-injection schemes

Microbial activities in soil near natural gas leaks

1972-01-01

From the present experiments it may be concluded that in the surroundings of natural gas leaks, methane, ethane and possibly some other components of the natural gas are oxidized by microbial activities as long as oxygen is available. This is demonstrated by an increased oxygen consumption and carbon dioxide production, as well as by increased numbers of different types of bacteria. The resulting deficiency of oxygen, the excess of carbon dioxide, and perhaps the formation of inhibitory amounts of ethylene, are considered to be mainly responsible for the death of trees near natural gas leaks. Also the long period of time needed by the soil to recover, may be due to prolonged microbial activities, as well as to the presence of e.g. ethylene. The present experiments suggest that especially methane-oxidizing bacteria of the Methylosinus trichosporium type were present in predominating numbers and consequently have mainly been responsible for the increased oxygen consumption. However, some fungi oxidizing components of natural gas, including methane and ethane may also have contributed to the increased microbial activities in the soil. The same will be true of a possible secondary microflora on products derived from microorganisms oxidizing natural gas components. 12 references, 9 figures, 7 tables.

2000-01-01

Liquefied natural gas (LNG) is being developed as a heavy vehicle fuel. The reason for developing LNG is to reduce our dependency on imported oil by eliminating technical and costs barriers associated with its usage. The U.S. Department of Energy (DOE) has a program, currently in its third year, to develop and advance cost-effective technologies for operating and refueling natural gas-fueled heavy vehicles (Class 7-8 trucks). The objectives of the DOE Natural Gas Vehicle Systems Program are to achieve market penetration by reducing vehicle conversion and fuel costs, to increase consumer acceptance by improving the reliability and efficiency, and to improve air quality by reducing tailpipe emissions. One way to reduce fuel costs is to develop new supplies of cheap natural gas. Significant progress is being made towards developing more energy-efficient, low-cost, small-scale natural gas liquefiers for exploiting alternative sources of natural gas such as from landfill and remote gas sites. In particular, the DOE program provides funds for research and development in the areas of; natural gas clean up, LNG production, advanced vehicle onboard storage tanks, improved fuel delivery systems and LNG market strategies. In general, the program seeks to integrate the individual components being developed into complete systems, and then demonstrate the technology to establish technical and economic feasibility. The paper also reviews the importance of cryogenics in designing LNG fuel delivery systems

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

To alleviate the problem of the insufficient reserves of natural gas in China, coal-based synthetic natural gas (SNG) is considered to be a promising option as a source of clean energy, especially for urban use. However, recent study showed that SNG will not accomplish the task of simultaneous energy conservation and CO 2 reduction. In this paper, life cycle costing is made for SNG use in three main applications in residential sector: heating, household use, and public transport. Comparisons are conducted between SNG and coal, natural gas, liquefied petroleum gas (LPG), diesel, and methanol. The results show that SNG is a competitive option only for household use. The use of SNG for heating boilers or city buses is not as cost-effective as expected. The biggest shortcoming of SNG is the large amount of pollutants generated in the production stage. At the moment, the use of SNG is promoted by the government. However, as shown in this paper, one can expect a transfer of pollution from the urban areas to the regions where SNG is produced. Therefore, it is suggested that well-balanced set of environmental damage-compensating policies should be introduced to compensate the environmental losses in the SNG-producing regions. - Highlights: • Life cycle costing was applied on the coal-based SNG. • The SNG was compared with conventional fuels of three residential applications. • The SNG is not so cost-effective except of household use. • Ecological compensation policy is useful to deal with the transfer of pollutions

The Product's Quality and Services are fundamental topics in the globalized commercial relationship inclusive concern the measurements in natural gas. Considerable investments were necessary for industry especially about the quality control in the commercialized gas with an inclusion of the natural gas in Brazilian energetic resources The Brazilian Regulatory Agency, ANP - Agencia Nacional de Petroleo, Gas Natural e Biocombustiveis - created the Resolution ANP no.16. This Resolution defines the natural gas specification, either national or international source, for commercialization in Brazil and list the tolerance concentration for some components. Between of this components are the inert compounds like the CO{sub 2} and N{sub 2}. The presence of this compounds reduce the calorific power, apart from increase the resistance concern the detonation in the case of vehicular application, and occasion the reduction in the methane concentration in the gas. Controls charts can be useful to verify if the process are or not under Statistical Control. The process can be considerate under statistical control if the measurements have it values between in lower and upper limits stated previously The controls charts can be approach several characteristics in each subgroup: means, standard deviations, amplitude or proportion of defects. The charts are draws for a specific characteristic and to detect some deviate in the process under specific environment conditions. The CEG - Companhia de Distribuicao de Gas do Rio de Janeiro and the DQUIM - Chemical Metrology Division has an agreement for technical cooperation in research and development of gas natural composition Concern the importance of the natural gas in the Nation development, as well as the question approaching the custody transference, the objective of this work is demonstrate the control quality of the natural gas composition between the CEG laboratory and the DQUIM laboratory aiming the quality increase of the

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

The fourth article in a series about changes in the European natural gas market focuses on Russia, a country with gigantic potential reserves (216,000 billion m 3 ) and a production unequalled in the world (780.4 billion m 3 in 1992 in the Russian Federation), but also with enormous economic and technical problems. The question is what role Russia is able to play in the European natural gas supply. Attention is paid to the organizational structure in former Soviet Union regarding the natural gas industry, the environmental effects of exploration and exploitation, the need for foreign capital, and the disappointing progress of the 1991 Energy Charter. On a short term the infrastructure must be improved. Also the conflicts on the price of natural gas transport between the transfer countries Ukraine, Slovenia and Czechoslovakia and the West-European clients must be solved. 1 fig., 7 ills., 2 tabs

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

Oil and natural gas exploration and production (E&P) activities generate emissions from diesel engines, compressor stations, condensate tanks, leaks and venting of natural gas, construction of well pads, and well access roads that can negatively impact air quality on both local and regional scales. A mobile, autonomous air quality monitoring laboratory was constructed to collect measurements of ambient concentrations of pollutants associated with oil and natural gas E&P activities. This air-monitoring laboratory was deployed to the Allegheny National Forest (ANF) in northwestern Pennsylvania for a campaign that resulted in the collection of approximately 7 months of data split between three monitoring locations between July 2010 and June 2011. The three monitoring locations were the Kane Experimental Forest (KEF) area in Elk County, which is downwind of the Sackett oilfield; the Bradford Ranger Station (BRS) in McKean County, which is downwind of a large area of historic oil and gas productivity; and the U.S. Forest Service Hearts Content campground (HC) in Warren County, which is in an area relatively unimpacted by oil and gas development and which therefore yielded background pollutant concentrations in the ANF. Concentrations of criteria pollutants ozone and NO2 did not vary significantly from site to site; averages were below National Ambient Air Quality Standards. Concentrations of volatile organic compounds (VOCs) associated with oil and natural gas (ethane, propane, butane, pentane) were highly correlated. Applying the conditional probability function (CPF) to the ethane data yielded most probable directions of the sources that were coincident with known location of existing wells and activity. Differences between the two impacted and one background site were difficult to discern, suggesting the that the monitoring laboratory was a great enough distance downwind of active areas to allow for sufficient dispersion with background air such that the localized

The amount of natural gas resources accessible via proven production technology and existing infrastructure is declining. Therefore, smaller and less accessible gas fields are considered for commercial exploitation. The research project Enabling production of remote gas builds knowledge and technology aiming at developing competitive remote gas production based on floating LNG and chemical gas conversion. In this project, scenarios are used as basis for directing research related to topics that affect the overall design and operation of such plants. Selected research areas are safety, environment, power supply, operability and control. The paper summarises the scenario building process as a common effort among research institutes and industry. Further, it documents four scenarios for production of remote gas and outlines how the scenarios are applied to establish research strategies and adequate plans in a multidisciplinary project. To ensure relevance of the scenarios, it is important to adapt the building process to the current problem and the scenarios should be developed with extensive participation of key personnel.
