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

    1992-01-01

    Natural gas is being viewed by many as the fuel of the 1990s and beyond because of its environmental qualities, relatively low cost and significant domestic resource base. However, in the Fall of 1991, a group of electric utility executives met with then Deputy Secretary of Energy Henson Moore and asserted that an inability to obtain long term gas contracts meant that supplies are unreliable and construction of gas-fueled generating stations is being discouraged. This study was requested by the Deputy Secretary to address the issues surrounding long-term gas contracts and supply reliability. The relationship between supply reliability and contracts is explained in terms of the number of buyers and sellers in a market. With the appropriate state regulatory policies, utilities can contract for gas and obtain reliable supplies at competitive market prices. Public utility commissioners are encouraged to permit utilities a free choice in signing gas contracts, but to allow only competitive market prices to be reflected in allowable fuel costs

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

    International Nuclear Information System (INIS)

    1992-08-01

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

    In the process of the deregulation of the energy market large consumers will have lots of opportunities to purchase natural gas and electricity cheaper than before. However, only one third seizes those opportunities. Special consultants can help to conclude supply contracts, focusing on the customer, supplier and commodity. Advantages and disadvantages of collective purchases of energy are briefly outlined

  10. Long-term contracts for European gas supply - an empirical analysis of the changing nature of pipeline and LNG-contracts

    International Nuclear Information System (INIS)

    Neumann, Anne

    2005-01-01

    As the structure of the European natural gas market is evolving towards more competition and more diverse market structures than before, the nature of the long-term contracts for European natural gas supply is also undergoing change. Experience from other liberalization processes, such as in the U.S. or the UK, suggests that the importance of long-term contracts diminishes over time, but that they remain an important element of supply. In Europe long-term contracts are still considered as a firm basis for investment and financing of capital-intensive infrastructure with a high degree of asset and relationship-specificity. Literature on institutional economics also suggests that long-term contracts act as a device to overcome the ''hold-up'' problem of relationship-specific investments in infrastructure (Klein, Crawford, and Alchian, 1987; Williamson, 1975, 1985). On the other hand, Hartley and Brito (2002) show that more flexible markets also imply a lower degree of asset specificity, thus requiring less fixed contracts. This paper explores the changing nature of long-term contracts for European natural gas supply, with a particular focus on differences between contracts for pipeline gas and liquefied natural gas (LNG). Traditionally, Europe relied on very long-term contracts for pipeline gas (Russia, Norway, Algeria). More recently, increasing LNG supplies are contemplated as a more flexible source of natural gas: The international LNG market is becoming more flexible, LNG can be sourced from a variety of sellers, and the cost of LNG supplies and infrastructure is coming down rapidly (Jensen, 2004). Thus, the evaluation of investing in LNG infrastructure (and the so bought flexibility and possibility of arbitraging profits) may be higher than committing to fixed/predetermined flows of pipeline gas. We ask whether this is reflected in the observed contracts. The paper is based on standard contract theory (Bolton and Dewatripont, 2005). We apply a microeconomic

    Hassan, F.

    1992-01-01

    Over the past 5 years the natural gas industry in North America has undergone substantial change as a result of the deregulated market. A comparison is provided of the key contract parameters in gas purchase contracts utilized by local distribution companies, industrial customers, cogenerators and marketers. Issues discussed include pricing mechanisms, indexed contracts, negotiated contracts, combinations, dispute resolution, supply, government regulation, industry structures, financial considerations, perception, geological influences, demand, transmission, storage, distribution, price trends and forecasts, Order 636 in the U.S., the evolution of North American market hubs, the futures market, and 'daisy chains' of connecting pipelines. 15 refs., 7 figs., 1 tab

    International Nuclear Information System (INIS)

    Creti, A.; Villeneuve, B.

    2004-01-01

    Theoretical and empirical research on long-term contracts inspired by the American experience are surveyed, with emphasis on the analysis of the role of take-or-pay clauses and price indexation rules, and whether regulation distorts optimal contract duration. The underlying motivation is to analyze the economic fundamentals of the European Union provisions on long-term contracts in the natural gas industry, and to highlight the features that differentiate them from the American experience. The impacts of long term contracts in the opening to competition of the European Union natural gas sector, and the apparent confusion between contract duration and flexibility as applied to long-term contracts in the European Union, are also explored. 29 refs., 2 tabs

    This report finds that natural gas-fired power plants purchase fuel both on the spot market and through firm supply contracts; there do not appear to be clear drivers propelling power plants toward one or the other type. Most natural gas-fired power generators are located near major natural gas transmission pipelines, and most natural gas contracts are currently procured on the spot market. Although there is some regional variation in the type of contract used, a strong regional pattern does not emerge. Whether gas prices are higher with spot or firm contracts varies by both region and year. Natural gas prices that push the generators higher in the supply curve would make them less likely to dispatch. Most of the natural gas generators discussed in this report would be unlikely to enter firm contracts if the agreed price would decrease their dispatch frequency. The price points at which these generators would be unlikely to enter a firm contract depends upon the region that the generator is in, and how dependent that region is on natural gas. The Electric Reliability Council of Texas (ERCOT) is more dependent on natural gas than either Eastern Interconnection or Western Interconnection. This report shows that above-ground storage is prohibitively expensive with respect to providing storage for an extended operational fuel reserve comparable to the amount of on-site fuel storage used for coal-fired plants. Further, both pressurized and atmospheric tanks require a significant amount of land for storage, even to support one day’s operation at full output. Underground storage offers the only viable option for 30-day operational storage of natural gas, and that is limited by the location of suitable geologic formations and depleted fields.

    NYMEX (New York Mercantile Exchange) is one of the United States' largest commodity exchanges. The primary role of commodity exchanges were summarized as well as the characteristics of an effective exchange. The concept of commoditization, price risk and price volatility were explained. The evolution of world and domestic regulated energy markets, the characteristics of the futures market, NYMEX electricity futures contract specifications, natural gas and crude futures contract development, and the nature of hedging were reviewed. Differences of risk management practices in cash markets and futures markets were illustrated. tabs., figs

    2003-01-01

    This presentation described different styles of gas contracts. When markets opened in 1986, many contracts were between end users and producers, and a few marketers. Typically, contracts were for a fixed price and term. In 1990, when gas futures contracts began trading on NYMEX, contracts began to have floating prices, and prices linked to NYMEX prices. Standard gas contracts were developed in the mid-late 1990s. This paper described the differences between plain retail gas contracts, retail gas contracts between mass marketers and end users, wholesale contracts, contracts between producers and marketers, transportation contracts and domestic contracts. Both contracting parties obtain business and legal advice from consultants and lawyers with knowledge in energy transactions. Master agreement contracts were also described with reference to the Gas EDI contract. Examples of changing regulatory requirements were also outlined along with some traps to avoid. Bundled transportation agreements are standard documents that can be negotiated in special circumstances to charge customers who fail to deliver. They should be considered as tariffs

    Brett, J.T.

    1999-01-01

    The special features of gas contracts for cogeneration projects were discussed. It was recommended that a gas power purchase contract should be entered early in a project development cycle to justify requests for new pipeline facilities. Issues regarding buyer's commitments, market prices, and volumes were also discussed. In the event of failure to deliver, the contract should include provisions which would make it possible to source gas elsewhere, terminate the contract or seek damages. This paper also discussed various pricing provisions in a gas commodity contract, security of supplies, gas transportation arrangements, regulatory considerations, outstanding issues, and IMO (independent market operator) requirements

    1999-01-01

    An overview of recent business trends impacting upon natural gas contracting in North America is provided. Among the trends examined are supply and demand, natural gas prices, access to the U.S. market, gas sales contracts, electronic gas sales, retail level marketing, the growing popularity of 'one-stop shopping', and standardization of contracts. Overall, supplies appear to be adequate for now, demand is growing, prices are volatile, short-term contracts are more popular than long-term ones, electronic commerce combined with one-stop shopping marketing at the retail level is growing, and standardization of spot and short-term gas sales contracts is slowly being accepted by industry as a means to to improve the efficiency of the market. 12 refs

    Van Gelder, J.W.

    1999-01-01

    In two articles, new types of contracts such as swaps, futures and spot contracts are surveyed. How far has the Dutch liberalised market developed in this field? This article focuses on the spot market for gas, whilst in the previous issue attention was paid to the electricity market. Bilateral spot contracts have been used in the Netherlands for years and years. The only gas exchange in Europe, the International Petroleum Exchange (IPE), was established in London, UK, at the end of 1994. This is a screen exchange, just like the APX (Amsterdam Power Exchange), where natural gas traders can enter into various types of contracts. An organised gas exchange has as yet not been established on the continent. The most suitable candidate is Zeebrugge in Belgium, where all the large players are represented. To do so, however, more transparency is required on the transmission market so that supply and demand can find each other quickly at standard conditions

  1. Dealing with security of supply issues in natural gas sales contracts

    International Nuclear Information System (INIS)

    Park, J. J.

    1999-01-01

    To avoid huge losses in a market where commodity prices can rise dramatically, gas marketers have developed a portfolio of contractual and non-contractual structures to avoid such losses. These structures had the effect of providing a sense of security that have proven to be false, or potentially false pending the outcome of decisions of appeal courts. This paper reviews these structures and examines some of the current issues. Non-contractual strategies employed by gas marketers include corporate warranty, dealing only with financially strong and reputable parties, limiting the dollar amount of exposure, and making short-term deals only. Contractual strategies include dedication of reserves (committing the gas produced from certain specified lands), requiring guarantee from corporate parent, letters of credit, or performance bonds. The concept of 'material adverse change' (MAC) a common method for dealing with the potential need for future security and its consequences, bankruptcies, receivership and set-off are explored and the manner in which the availability of set-off has changed following the recent Blue Range decision. In this decision the Court held that Enron's Master Agreement with Blue Range was not an 'eligible financial contract' because it contemplated the physical delivery of gas. Based on this decision it is possible to argue that set-off is no longer available for contracts intended for the physical delivery of natural gas. The collective consequence of these events and the recent spate of marketing failures require the gas marketing industry to review their forms of agreement and to reconsider their market exposure to any particular purchaser or supplier. The significant losses to companies that resulted from recent bankruptcies and insolvencies provide ample evidence that assuming a safe, closed position based on conventional gas marketing contracts is a risky proposition

    Electricity markets in the United States have witnessed unprecedented instability over the last few years, with substantial volatility in wholesale market prices, significant financial distress among major industry organizations, and unprecedented legal, regulatory and legislative activity. These events demonstrate the considerable risks that exist in the electricity industry. Recent industry instability also illustrates the need for thoughtful resource planning to balance the cost, reliability, and risk of the electricity supplied to end-use customers. In balancing different supply options, utilities, regulators, and other resource planners must consider the unique risk profiles of each generating source. This paper evaluates the relative risk profiles of renewable and natural gas generating plants. The risks that exist in the electricity industry depend in part on the technologies that are used to generate electricity. Natural gas has become the fuel of choice for new power plant additions in the United States. To some, this emphasis on a single fuel source signals the potential for increased risk. Renewable generation sources, on the other hand, are frequently cited as a potent source of socially beneficial risk reduction relative to natural gas-fired generation. Renewable generation is not risk free, however, and also imposes certain costs on the electricity sector. This paper specifically compares the allocation and mitigation of risks in long-term natural gas-fired electricity contracts with the allocation and mitigation of these same risks in long-term renewable energy contracts. This comparison highlights some of the key differences between renewable and natural gas generation that decision makers should consider when making electricity investment and contracting decisions. Our assessment is relevant in both regulated and restructured markets. In still-regulated markets, the audience for this report clearly includes regulators and the utilities they

  4. Tax shifting in long-term gas sales contracts

    2002-01-01

    Producers or consumers faced with an increase in taxes are usually able to shift parts of it to other levels in the value chain. We examine who are actually bearing the burden of increased taxes on natural gas in the EU-area - consumers or exporters. Strategic trade policy and cross-border consumer tax shifting are of particular interest, as the EU-area increasingly is a net importer of gas. Traditional tax incidence theory presumes spot markets. Natural gas in the EU-area, however, is to a large extent regulated by incomplete long-term contracts. Still, spot market forces could be indicative for tax shifting, by determining the ex post bargaining power in contract renegotiations. By examining tax shifting in gas sales data we test whether this is the case. To investigate tax incidence, we estimate natural gas demand elasticities for the household sector in EU countries as well as a reduced form import equation. We test whether gas import prices, which are predominantly determined by long-term contracts, have been influenced by end-user tax shifts. (author)

  5. Structuring spot, short and long term gas contracts

    International Nuclear Information System (INIS)

    Gretener, N.M.

    1996-01-01

    A review of the core clauses of the modern natural gas purchase and sales contracts, was presented. There exists a wide variety of terms which can be used by a seller and a buyer to customize such a contract to suit particular circumstances. On the basis of length of term, gas contracts may classified as spot contracts having a term of 30 days or less, short term contracts having a term of 30 days to one to two years, and long term contracts having terms greater than two years. The three key elements which are applicable to all gas sales contracts are the contract price, the seller's obligation to deliver, and the buyer's obligation to accept. Other provisions that may be included in any gas sales contract in addition to the basic three were reviewed, including market pricing, load factor incentive pricing, seasonal pricing, pipeline demand charges, market shares, and the seller's right to decontract

    A common clause in a gas purchase contract is one that provides for specific damages for the non-performance of an obligation. As a rule, damages will be calculated based on the loss in the value of the bargain plus those losses foreseeably caused by the breach of contract. the rationale being to put the non-breaching party in as good a position as it would have been had the contract been performed. This paper examines the complex issues involved assessing and measuring damages, the concept of injunctive relief in circumstances where damages will be inadequate or insufficient to prevent injustice, the doctrine of mitigation, the extent of the right of set-off between different contracts, and the impact of bankruptcy and insolvency laws on the exercise of remedies. Four case histories are presented to illustrate the Courts' treatment of gas purchase contracts in the context of bankruptcies and /or insolvencies. 36 refs

    This paper reviews the growing power and economic strength of Enron Corp., a natural gas distributor and exploration company. The paper reviews the policy of the company to exploit deregulation at home and privatization of all sorts of energy companies abroad. Enron is actively building its own power plants in the US and has successfully boosted their profits by 20 percent in what was considered a flat natural gas market. The paper goes on to discuss the company's view of the new energy tax and how it should benefit natural gas companies as a whole. Finally the paper reviews the contracting procedures of the company to secure long-term fixed price contracts in a volatile market which precludes most companies from taking the risk

  10. Natural gas: an environmental-friendly solution?

    International Nuclear Information System (INIS)

    Vermeire, J.

    1994-01-01

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

  11. Deregulation, market structure and gas prices in the Canadian Natural Gas Industry

    International Nuclear Information System (INIS)

    Uhler, R.S.

    1992-01-01

    During the course of the development of the natural gas industry in Canada, gas purchase and sales markets have evolved from being relatively free of regulation to being highly regulated and back again. Though pipeline transport charges were regulated, the pipeline companies, or their subsidiaries, owned the gas that they transported and price and other provisions of purchase and sales contracts were freely negotiated with the producers at one end and distributing utilities or industrial users at the other end. The Western Accord of 1985 set the process of deregulation of the Canadian natural gas industry in motion. On November 1, 1986, natural gas prices in interprovincial trade were deregulated in that domestic natural gas prices were to be freely negotiated. Although not stated explicitly, government policy is to permit export prices to be freely negotiated so long as they do not fall below domestic prices. The deregulation process has dramatically changed the relationship between buyers and sellers. Of particular importance is that deregulation has permitted companies to negotiate gas purchase contracts directly with producers with the pipeline company acting solely as a gas transporter. The purpose of this paper is to examine the forces that have led to shorter term contracts and to examine the likely effect of these contract terms on reservoir development investment incentives. 5 refs., 3 figs

    Development of the U.S.-Canadian natural gas market as it is today and the issues that may arise in cross-border transactions involving natural gas contracts between the two countries are reviewed. In this context, the paper reviews recent history of U.S.-Canadian trade relations culminating in the development of NAFTA, the U.S. regulatory and legislative framework surrounding cross-border natural gas transactions, and general U.S. foreign trade policy that may come into play at the U.S.- Canada border. The paper also examines certain issues arising in the U.S. commercial context that may be of interest to Canadian corporations, specifically the U.S. Uniform Commercial Code, state jurisdiction on the U.S. side of the border, state and federal tax concerns, and the mechanics and potential benefits for a Canadian parent company in forming a U.S.-based subsidiary to handle U.S.-Canada natural gas transactions. 71 refs

  14. Long term contracts in portfolios of gas supply

    International Nuclear Information System (INIS)

    Burns, D.

    1992-01-01

    This paper promotes the idea of long-term contracting for natural gas local distributors and utilities. It presents a brief history of how the spot-market developed and the effects spot-marketing can have in times of supply shortages. This has also resulted in a drastic decrease in exploration and development in the gas industry as gas supplies have exceeding demand, driving the prices down. The paper proposes several methods to restabilize the long-term contracting of gas by considering volume and pricing flexibility. Some brief discussions of industry-wide statistics are presented to show reserve replacement costs which would be needed to preserve the industry in a profit-making situation

  15. Alternative natural gas contract and pricing structures and incentives for the LNG industry

    1991-01-01

    Gas conversion to liquefied gas (LNG) and transport by LNG tankers is one option for meeting expanding gas consumption and for gas traded internationally. This paper examines the impact of the traditional gas contract provisions of indefinite pricing, market out price ceilings, and take-or-pay requirements on the profitability of LNG projects in the context of markets characterized by price and quantity uncertainty. Simulation of experiments are used to examine and calibrate the effects of those provisions. The results provide guidance to operators, host countries and purchasers in structuring such contracts. The paper also assesses prospects of future expansion of world LNG capacity. (author). 11 refs, 3 figs, 4 tabs

    This paper analyses the economics of long-term gas contracts under changing institutional conditions, mainly gas sector liberalisation. The paper is motivated by the increasingly tense debate in continental Europe, UK and the US on the security of long-term gas supply. We discuss the main issues regarding long-term contracts, i.e. the changing role of the flexibility clause, the effect of abandoning the destination clause, and the strategic behaviour of producers between long-term sales and spot-sales. The literature suggests consumers and producers benefit from risk hedging through long-term contracts. Furthermore long-term contracts may reduce exercise of market power. Our analysis adds an additional benefit if the long-run demand elasticity is significantly lower than the short-run elasticity, both strategic producers and consumers benefit from lower prices and larger market volume. Some policy implications of the findings are also discussed. (Author)

    A review of the core clauses of the modern natural gas purchase and sales contracts, was presented. There exists a wide variety of terms which can be used by a seller and a buyer to customize such a contract to suit particular circumstances. On the basis of length of term, gas contracts may classified as spot contracts having a term of 30 days or less, short term contracts having a term of 30 days to one to two years, and long term contracts having terms greater than two years. The three key elements which are applicable to all gas sales contracts are the contract price, the seller`s obligation to deliver, and the buyer`s obligation to accept. Other provisions that may be included in any gas sales contract in addition to the basic three were reviewed, including market pricing, load factor incentive pricing, seasonal pricing, pipeline demand charges, market shares, and the seller`s right to decontract.

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

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

    1991-01-01

    The New York Mercantile Exchange (NYMEX) natural gas futures contract was introduced on April 3, 1990, offering natural gas producers, marketers, and end users an important new tool to manage price risk. Each NYMEX natural gas contract unit consists of 10,000 million Btu and trades over twelve consecutive months. The NYMEX delivery location is at the Henry Hub in Erath, Louisiana. The contracts are designed to align with certain industry practices, including pipeline nomination deadlines and traditional bid-week pricing. Contract volume has grown to an average daily figure of nearly 1,400 in the first 18 months of contract trading. A peak volume of 8,739 contracts was achieved on June 24, 1991. End-users currently represent under 2% of the futures market. The ratio of open interest to volume is very low, indicating the high concentration of commercial vs investor interest in the natural gas futures market. Gas marketers are the most active users of the futures market, making up over 60% of reportable open interest. Many producers, end-users, and local distribution companies hedge indirectly through marketers. The next largest holders of open interest are producers. A few local distribution companies are also entering the futures market, and interest in this market from all segments of the industry is increasing. 3 figs

    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.

    The paper relates studies regarding the natural gas distribution network interruptible branch. This new service can be appropriate for thermal power generation on flexible dispatch mode, as 'take or pay' contracts surplus jobs. The paper indicates no regulatory restraints in an interruptible network implantation. The final conclusion is that interruptible contracts can be an improvement on the distribution business and certainly can accommodate a suitable demand and supply volumes in the long-term gas market balance.

  2. 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

  3. Contracting out gas processing : the pros and cons

    International Nuclear Information System (INIS)

    Stout, D.L.

    1999-01-01

    The impact of competition within the energy industry on the midstream infrastructure was discussed. It was demonstrated that it is no longer necessary to own all or a portion of a processing facility to be a successful exploration company. It is now possible for midstream operators to manage the transmission business, the gas storage sector and the gas processing segment of the industry. Contract options and issues that should be addressed by natural gas producers in determining risks involved in contracting out were summarized. Changes in the industry has greatly expanded the options and opportunities for companies, both upstream and midstream. The industry has been contracting out gas processing for many years. However, the entry into the business of the specialized midstream player should further enhance the producer's options. The ultimate goal for the producer should be to benefit from lower costs, long term offerings, and a reduced need to invest potential exploration capital into non-core processing facilities

    The aim of this paper is to analyse the capacity of the 'inflexible production', by state-owned Brazilian company PETROBRAS at its natural gas-based thermo-electrical generation stations, to promote in a increase in the use of the Brazil- Bolivia Gaspipe (Gasbol), which is the natural gas transport pipe related to 90,66% of the Brazilian natural gas imports. As the contract is a 'take or pay' contract, Brazil ends up paying for such a large volume of gas that the country does not effectively consume, since the consume of natural gas in Brazil has not come to the expectations which were prevailing when the import contract was signed. Last but not least, this article addresses the future possibilities for the increase of the share of natural gas in the total Brazilian energy consumption. (author)

    1998-01-01

    While the daily newspapers and radio are full of articles and advertisements concerning the impending opening up of the electric industry to customer choice of supplier, little attention is being given to choice in the natural gas markets. The fact is, however, that except for California and some scattered pilot programs, retail electric markets are not yet open and even the imminent deadlines for retail access may prove to be illusory. For example, Rhode Island retail electric markets, by law, were open to competition July 1, 1997 but a month later less than a handful of customers had chosen alternative suppliers. In contrast, customers everywhere are already able to choose their own gas supplier, other than the local gas utility that had supplied all customers for so many years. With this new freedom of choice comes not only a number of benefits, but also risks. This article seeks to provide customers some guidance in obtaining such benefits and avoiding the risks. Ultimately, that is accomplished through a careful selection process, best done by means of an RFP with expert assistance, and through a negotiated gas contract. Before addressing specific contracting issues one must understand the legal and regulatory framework which governs the transportation of the natural gas

  7. Southwest British Columbia natural gas supply and deliverability: Discussion paper

    International Nuclear Information System (INIS)

    1994-02-01

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

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

    1996-01-01

    A general overview of certain fundamental issues of contract law, which are relevant to gas sales transactions, was presented. Since deregulation, parties of the Canadian natural gas market are free to negotiate the terms of arrangements and contracts with any number of buyers and sellers. With deregulation also came a substantial increase in the amount of litigation regarding sales contracts. Two basic issues that should be kept in mind when negotiating any gas sales contract were letter agreements, (two versions of non-binding letters of intent), and requirement of writing. Within the requirements of writing one should be mindful of the legal implications of the fraud statutes, the Sale of Goods Act, what constitutes a sufficient note or memorandum, what constitutes the requisite signature, contracting out of the requirement of writing and signature on the mass agreement, certainty of terms, and the terms implied by legislation. It was considered advantageous for both buyers and sellers to continue to be vigilant about the contractual arrangements respecting all of their gas transactions

    Reschke, D. N.; Campbell, L. M.

    1999-01-01

    The place of 'force majeure' provisions, in gas purchase/sale contracts is discussed. This issue, not normally considered to be significant in gas purchase/sale contracts, became a matter of intense interest in the aftermath of the Atcor Ltd v. Continental Energy Marketing case when the trial court, as well as the Alberta Court of Appeals, strongly criticized the wording of the force majeure clause in the contract as containing a 'choice of words that assured litigation'. Force majeure, simply stated, refers to acts of God, (lightning, earthquakes, storms, floods, etc) and acts of war. It is inserted in contracts to limit the liability of parties to the contract in the event of inability to perform due to any of the above acts of God, or acts of war. In this particular case, the force majeure cause included, in addition to the above, a long list of other causes such as strikes, lockouts or other industrial disturbances, insurrections, riots, epidemics, landslides, fires, washouts, explosions of or accidents to plant, machinery or lines of pipe, well blowouts, and pipeline repairs and reconditioning. The trial court found the drafting of the clause archaic, circumventing clarity, and drearily lengthy. In view of the court's decision it is clear that more thought has to go into drafting force majeure decisions in the future. Accordingly, this paper attempts to discuss practical issues of drafting force majeure clauses that clearly reflect the parties' intentions and expectations so that costly litigations might be avoided, or if litigation is unavoidable, to at least have the outcome of such litigation be more predictable. The focus of the discussion is on legal interpretation issues, forms of gas contract force majeure provisions- events and consequences, and standardization of force majeure provisions. It is recommended that the drafter of such clauses should always keep in mind the potential impact that the strict construction and commercial reasonability concepts

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

    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)

    1992-01-01

    Although the incremental electricity generation market has the potential to be a major growth area for natural gas demand in the U.S., it may never live up to such promise unless gas suppliers are more willing to enter into long-term gas sales agreements necessary to nurture this segment of the industry. The authors submit that producer reluctance to enter into such long-term sales agreements can be traced, at least in part to the differing contract price requirements between gas producers and buyers. This paper will address an evolving solution to this contracting dilemma - the development of a two-part pricing structure for the gas commodity. A two-part pricing structure includes a usage or throughput charge established in a way to yield a marginal gas cost competitive with electric utility avoided costs, and a reservation charge established to guarantee a minimum cash flow to the producer. Moreover, the combined effect of the two charges may yield total revenues that better reflect the producer's replacement cost of the reserves committed under the contract. 2 tabs

    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

  6. Overview of the EPRI CONTRACTMIX model for natural gas applications

    International Nuclear Information System (INIS)

    1993-09-01

    The Contract Mix Model (CONTRACTMIX) is designed to assist gas supply planners in analyzing the costs and risks of alternative supply strategies. By explicitly incorporating uncertainty about gas demand and market conditions into the analysis, the methodology permits the analyst to compare contracting strategies on the basis of cost and risk and to assess the value of flexible strategies and contracts. The model is applicable to purchase decisions for natural gas and other fuels. CONTRACTMIX may be used at all phases of supply decision-making, from broad strategy formulation to detailed contract design and evaluation. This document introduces the prospective user to the model's capability for analysis of gas supply contracting decisions. The document describes the types of problems CONTRACTMIX is designed to address as well as the model's structure, inputs, outputs, and unique features

In this context this information paper presents the legislative and regulation framework of the natural gas consumers eligibility, a definition of the possible eligible consumers and a list at the 30 january 2004. It provides also recommendations and answers to the more often asked questions on the administrative procedures and the contracts. (A.L.B.)

  8. Essays on the economics of natural gas pipelines

    Science.gov (United States)

    Oliver, Matthew E.

    The natural gas pipeline transportation industry is comprised of a primary market and a secondary market. In the primary market, pipelines sell 'firm' transport capacity contracts to gas traders, local distribution companies, and other parties. The (per unit) secondary market value of transport is rarely comparable to the regulated primary market two-part tariff. When and where available capacity in the secondary market is scarce, its value can far exceed the primary market tariffs paid by firm contract holders, generating scarcity rents. The following essays demonstrate that this phenomenon has predictable effects on natural gas spot prices, firm capacity reservations, the pipeline's capacity construction and expansion decisions, and the economic welfare of producers and consumers at the market hubs connected by the pipeline. Chapter 1 provides a theoretical framework for understanding how pipeline congestion affects natural gas spot prices within the context of the current regulatory environment, and empirically quantifies this effect over a specific regional pipeline network. As available pipeline capacity over a given route connecting two hubs becomes scarce, the spot prices for gas at the hubs are driven apart---a phenomenon indicative of some market friction that inhibits the ability of spot price arbitrage to fully integrate the two prices, undermining economic efficiency. The theoretical component of Chapter 1 illuminates a potential source of this friction: the deregulated structure of the secondary market for gas transportation services. To support and quantify the predictions of the theoretical model, the empirical component demonstrates that the effect of congestion on the secondary market value of transport---the key factor in driving apart spot prices---can be quite strong. Coefficient estimates indicate that dramatic increases in transport costs are likely to result from marginal increases in congestion. This result has important implications because

  9. British Columbia natural gas: Core market policy

    International Nuclear Information System (INIS)

    1988-06-01

    The core market for natural gas in British Columbia is defined as all natural gas consumers in the residential, institutional, commercial, and industrial sectors not currently purchasing natural gas directly and not exempted from the core market by the British Columbia Utilities Commission (BCUC). The intent of the definition is to include all customers who must be protected by contracts which ensure long-term security of supply and stable prices. Core market customers are excluded from direct natural gas purchase and will be served by distribution utilities. A customer may apply to BCUC to leave the core market; such an application may be approved if it is demonstrated that the customer has adequate long-term natural gas supplies or alternative fuel supplies to protect him from supply interruptions. The non-core market is defined as all large industrial customers who elect to make their own natural gas supply arrangements and who can demonstrate to the BCUC sufficient long-term natural gas supply protection or alternative fuel capability to ensure security of the industry. Non-core market customers have full and open access to the competitive natural gas market. The British Columbia government will not apply its core market policy to other jurisdictions through Energy Removal Certificates

  10. Norwegian Natural Gas. Liberalization of the European Gas Market

    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

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

    2004-01-01

    Traditionally guided by long-term contracts, the international natural gas trade is experiencing new methods of operating, based on the short term and more flexibility. Today, indeed, the existence of uncommitted quantities of natural gas, combined with gas price discrepancies among different regions of the world, gives room for the expansion of the spot-trading of gas. The main objective of this paper is to discuss three fundamental risks related to the short-term trading of natural gas: volume risk, price risk and infrastructure risk. The defenders Of globalisation argue that the transition from the long-term to the short-term trading of natural gas is mainly a question of access to gas reserves, decreasing costs of gas liquefaction, the building of liquefied natural gas (LNG) fleets and regasification facilities and third-party access to the infrastructure. This process needs to be as short as possible, so that the risks related to the transition process will disappear rapidly. On the other hand, the detractors of globalisation put the emphasis on the complexity of the gas value chain and on the fact that eliminating long- term contracts increases the risks inherent to the international natural gas business. In this paper, we try to untangle and assess the risks related to the short-term trading of natural gas. Our main conclusions are: the short-term trading of gas is far from riskless; volume risk requires stock-building in both consuming and producing countries. (author)

  12. Supply chain management and economic valuation of real options in the natural gas and liquefied natural gas industry

    Science.gov (United States)

    Wang, Mulan Xiaofeng

    My dissertation concentrates on several aspects of supply chain management and economic valuation of real options in the natural gas and liquefied natural gas (LNG) industry, including gas pipeline transportations, ocean LNG shipping logistics, and downstream storage. Chapter 1 briefly introduces the natural gas and LNG industries, and the topics studied in this thesis. Chapter 2 studies how to value U.S. natural gas pipeline network transport contracts as real options. It is common for natural gas shippers to value and manage contracts by simple adaptations of financial spread option formulas that do not fully account for the implications of the capacity limits and the network structure that distinguish these contracts. In contrast, we show that these operational features can be fully captured and integrated with financial considerations in a fairly easy and managerially significant manner by a model that combines linear programming and simulation. We derive pathwise estimators for the so called deltas and structurally characterize them. We interpret them in a novel fashion as discounted expectations, under a specific weighing distribution, of the amounts of natural gas to be procured/marketed when optimally using pipeline capacity. Based on the actual prices of traded natural gas futures and basis swaps, we show that an enhanced version of the common approach employed in practice can significantly underestimate the true value of natural gas pipeline network capacity. Our model also exhibits promising financial (delta) hedging performance. Thus, this model emerges as an easy to use and useful tool that natural gas shippers can employ to support their valuation and delta hedging decisions concerning natural gas pipeline network transport capacity contracts. Moreover, the insights that follow from our data analysis have broader significance and implications in terms of the management of real options beyond our specific application.

  13. Changing incentives for long-term gas contracts

    1992-01-01

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

  14. Two 'hot buttons' in gas contracting: security performance and force majeure

    International Nuclear Information System (INIS)

    Park, J.J.

    1996-01-01

    Two important developments in gas contracting issues are the 'force majeure' provisions and security for performance clauses. 'Force majeure' was defined as any acts of God or any acts of omission by a transporter of gas, which is excused by any event not within the control of the party claiming suspension. 'Force majeure' provisions need to be specifically negotiated in every case. These issues often arise in gas contracting situations, but the nature of Canada's non-litigious oil and gas industry is such that we have had little or no Canadian case law to assist in interpreting what these clauses mean. The 'force majeure' clause is basically meant to protect the parties from events outside normal business risk. The security of performance issue arises when the obligation of a supplier of gas to perform, and the obligation of a buyer of gas to pay, is unsecured, as would be the case for example, if one of the parties becomes bankrupt

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

    Since the oil crisis the buyers's market started to change to a seller's market as a result of the worldwide rising demand for natural gas. This development will be amplified with the increasing significance and volume of LNG trade. This depends upon the availability of handling and tanker capacities. It is considered that technical solutions are available. The internationalisation of the world natural gas market imposes changes in terms of trade for the Federal Republic of Germany. In the sixties, terms of trade made under sales considerations presented no problems. But gas buyers today are forced to accept sellers' terms looking for the buyer offering the highest prices and other sales advantages. The world gas market has assumed the features of a polypolistic market. The security of supply is not a matter of adequate reserves, but almost entirely that of terms of contract on which the natural gas supply can be ensured. It is thereby decisive, whether it will be possible in future to procure the required amount of gas at such terms that it can be sold on the German energy market at competetive rates.

  17. US gas line contract carriage on the rise

    This paper reports that the Interstate Natural Gas Association of America reports contract carriage moved 84% of the gas delivered to U.S. markets in 1991, up from 79% the previous year. Carriage for market transportation for distributors, end users, and marketers totaled 15.2 quadrillion BTU, a 13% increase from the 13.4 quads reported at the end of 1990. Ingaa the growth in carriage volumes has slowed. This year's 13% increase is lower than the 28% growth in carriage volumes from 1988 to 1989 and the 72% from 1986 to 1987. Total natural gas delivered to market was 18 quads in 1991, an increase of 5% from the 1990 level of 17.1 quads. Pipeline sales accounted for only 16% of the gas delivered to market in 1991. They dropped 0.8 quads, or 22%, from 1990 levels. Ingaa the while the market relies heavily on carriage throughout the year, reliance on carriage is somewhat heavier as has been the case since 1986 during the off peak season in April-September

  18. Natural gas cost for evaluating energy resource opportunities at Fort Stewart

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

    The Bolivia oil industry nationalization in 2006 and the high price of oil on the international market called the public and government attention to the problems of the natural gas industry regulation in Brazil. Recently, the establishment of a specific law for the natural gas industry had been debated in academic circles and in government institutions. In Brazil, the absence of an integrated energy policy and the absence of a homogeneous regulatory framework interfere with natural gas industry development, especially in distribution. Thus, the objective of the work will be contrast the Colombia distribution natural gas regulatory structure sector to the Brazilian natural gas regulatory framework. The comparison of the Brazilian regulatory framework and the Colombian natural gas regulation shows that the existence of different kinds of concession contracts in distribution is one of the explanations for the different levels of investment in Brazil. The contract with exclusive right to explore the distribution service in geographic territories also contributes to explain the low coverage rate of public distribution companies. Thus, the rapid expansion of the natural gas distribution network in Colombia after the regulatory reforms shows the importance of the establishment of a regulatory structure to push private investment. The Colombian case can be considered a good model for other countries in South America, especially to the natural gas distribution regulation. (author)

    The deregulation of natural gas markets in North America has resulted in greater quantities of gas being sold under indexed price agreements. As this is occurring, natural gas storage facilities are being developed and opened up for the use of natural gas producers and marketers. While natural gas spot prices continue to exhibit some strong seasonality reflecting higher demand peak in winter, traded futures contract prices tend to discount the expected market price. The elements which contribute to this differential are examined and some of the possible opportunities for the use of gas storage in tandem with other risk management instruments are demonstrated. The specific scenario to be evaluated takes the viewpoint of a natural gas producer considering the storage and later withdrawal of gas to take some advantage of an anticipated seasonal and/or secular price increase, with the objective of locking in future prices for current production. Gas would be stored in a low season and later withdrawn and sold, with the price covered by a futures contract or by a dynamic hedging strategy. The expected returns from a natural gas storage/withdrawal scheme are analyzed and the implications of market volatility, price of risk, the local cost of storage, and observations regarding the convenience yield (a difference between the current spot market price and futures market price for future periods) are presented. Analysis of gas storage proposals of specific duration is included as well as evaluation of potential put options created when the storage duration is not fixed. 6 refs., 4 figs., 4 tabs

This would be a threat to consumers' security of supply. (Author)

Ahead of the insertion of new players, the regulation of the sector was given for the Law (no. 9.478/97), as well for legal acts edited for the National Agency of the Oil - ANP. Meanwhile, the Oil norm little disciplined the industry of the natural gas that, for its peculiarities, imposes specific rules. In this context, the transport of the natural gas by means of ducts become prominent for the lack of debates on the correct form to classify them. The present work has for target to analyze the legal types instituted by the Law and for the ANP acts for the ducts, as form of if having a correct understanding of the matter. Thus, will reveal as each one of the adopted classifications can cause (or not) the incidence of the ICMS, or either, as the legal regimen of the gas-lines is correlated with the tax. (author)

  13. Eastern Canada natural gas developments

    International Nuclear Information System (INIS)

    Wall, A.

    2001-01-01

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

  15. Evaluation of long-term natural gas marketing agreements: An application of commodity forward and option pricing theory

    1993-01-01

    Methods that have been empirically validated in the analysis of short-term traded securities are adapted to evaluate long-term natural gas direct-sale contracts. A sample contract is examined from the perspective of the producer, and analyzed as a series of forward and option contracts. The assessment of contract value is based on the gas price forecast, the volatility in that forecast, and the valuation of risk caused by that volatility. The method presented allows the gas producer to quantify these elements, and to evaluate the variety of terms encountered in direct-sale natural gas agreements, including features such as load factors and penalty charges. The analysis uses as inputs a probabilistic price forecast and a determination of a price of risk for gas prices. Once the forecast volatility is derived from the probabilistic forecast, the forward contracts imbedded in the long-term gas contract can be valued with a risk-discounting model, and optional aspects can be evaluated using the Black-Scholes option pricing method. 10 refs., 3 figs., 2 tabs

  16. Russian natural gas policy and its possible effects on European gas markets

    Quast, O.; Locatelli, C.

    1997-01-01

    There is a growing perception among Western European gas experts that Russia has developed a considerable gas surplus - the Russian gas bubble. Thus, the question clearly arises how much gas is available for export and how much gas, over the next 15 to 20 years, can the Russian quasi-monopolist Gazprom market in Western Europe. We consider that Gazprom's export strategy mirrors the approach of Russia's natural gas policy towards the Western European market. In this paper, we will focus on the characteristics of Gazprom's export strategy, its underlying logic, and its impact on Western European gas markets. As a consequence of Gazprom's export strategy, the Russian gas company faces today a price quantity dilemma. Gazprom's problem is to place as much gas as possible in the growing Western European gas market, without destroying downstream gas prices. We argue that Gazprom has adopted a market share expansion and downstream vertical integration strategy, aimed at capturing a part of the downstream gas rent. Although this strategy appears to have initiated a form of gas to gas competition in a number of European consumer markets, this strategy is not based on an aggressive price policy. However, in order to live up to its ambitions, there is a chance that Gazprom will have to somewhat relax traditional contract clauses, such as contract length, indexation terms and take or pay conditions.

  18. Natural gas for utility generation

    International Nuclear Information System (INIS)

    Moore, T.

    1992-01-01

    Forecasters predict that natural gas will be the dominant fuel choice for utility capacity additions in the coming decade and that power generation will be by far the largest growth market for gas sales. While gas's low emissions, high efficiency potential, and present low cost argue persuasively for a surge in gas-fired generation, many utilities have been slow to commit to a gas future, citing reasoned concern about long-term price trends and the ability of gas suppliers to deliver the fuel where and when it will be needed. Meanwhile, the relatively low cost of gas-fired units is providing an opportunity for independent power producers to compete strongly with utilities for generation contracts. EPRI studies suggest that a sound, competitive strategy will be based not on how much gas a utility burns, but rather on how this capacity fits into its overall generating mix at various fuel price levels. Gas suppliers will need to pay special attention to the operating needs of power generators if they are to solidify this important market

  19. Planning of optimum production from a natural gas field

    1968-03-01

    The design of an optimum development plan for a natural gas field always depends on the typical characteristics of the producing field, as well as those of the market to be served by this field. Therefore, a good knowledge of the field parameters, such as the total natural gas reserves, the well productivity, and the dependence of production rates on pipeline pressure and depletion of natural gas reserves, is required prior to designing the development scheme of the field, which in fact depends on the gas-sales contract to be concluded in order to commit the natural gas reserves to the market. In this paper these various technical parameters are discussed in some detail, and on this basis a theoretical/economical analysis of natural gas production is given. For this purpose a simplified economical/mathematical model for the field is proposed, from which optimum production rates at various future dates can be calculated. The results of these calculations are represented in a dimensionless diagram which may serve as an aid in designing optimum development plans for a natural gas field. The use of these graphs is illustrated in a few examples.

    Highlights: ► An optimization model for daily operation of a natural gas-fired generation company is proposed. ► The model considers uncertainties in electricity price and natural gas price. ► The model is formulated to capture the hedging decisions by the company. ► The solution yields quantities of natural gas, generating schedule and purchasing quantities of electricity. ► Higher profit can be achieved by adapting inventory and production to the actual spot prices of natural gas and electricity. - Abstract: This paper considers a deregulated electricity market environment where a natural gas-fired generation company can engage in different types of contracts to manage its natural gas supply as well as trade on the electricity market. If the contracts are properly designed, they can protect the company from fluctuations in electricity price and demand, at some cost to the company’s expected profit. This reduction in profit can be mitigated by trading on the natural gas and electricity spot markets, but this trading activity may also sometimes result in losses. A stochastic programming model is formulated to capture the hedging decisions made by the company, as well as the interactions between the natural gas and electricity markets. The benefits offered by this approach for profit maximization in a variety of business scenarios, such as the case where the company can hold some amount of gas in storage are studied and presented. It is found that the stochastic model enables the company to optimize the electricity generation schedule and the natural gas consumption, including spot price transactions and gas storage management. Several managerial insights into the natural gas market, natural gas storage, and distribution profit are given

  1. Partner Country Series: Developing a Natural Gas Trading Hub in Asia

    2013-06-01

    The trading of natural gas in the Asia-Pacific region is dominated by long-term contracts in which the price of gas is indexed to that of oil. As the price of gas between Asia and other parts of the world has widened in recent years, observers have raised serious doubts about the sustainability of this pricing model. In this report, the IEA shows what it would take to create a functional, regional natural-gas trading hub in which prices reflect the local supply and demand fundamentals. The report aims to provide stakeholders with insights on the changes that are required in the Asia-Pacific natural gas sector - both downstream and upstream - to allow a competitive natural gas price to emerge. Building on OECD Europe and OECD America experiences, this report sets out to assess perspectives for these changes in the Asia-Pacific natural gas markets. It identifies obstacles and opportunities for a competitive natural gas price in the Asian economies to emerge.

    2012-07-01

    Since the first New Energy Auction (LEN), held in December 2005, there has been a continuous process of improving the auction rules and mechanism. For the specific case of gas-fired plants, a significant change was observed between the LEN A-3/2011 and LEN A-5/2011, and refers to the need of natural gas ballast for candidate projects in the auction. This rule was introduced by ANP Resolution No. 52, which establishes that the gas supply agreements must be backed up by proven reserves (analogous to the requirement in the power sector contracts of physical guarantee backup), and Ordinance MME No. 21/2008, which deals with power plants qualification for the new energy auctions. The latter was amended by MME Ordinance No. 514, which requires proven natural gas reserves to support the GSA of all candidate projects in a LEN. In other words, the gas supplier now has to prove that there are sufficient gas reserves to meet requirements of all candidate project in an auction, regardless of the plausibility of their engagement in the auction. In this context, the present study discusses these issues and has as main contributions: (I) a review of current regulations on contract ballast in the Brazilian natural gas sector, (II) a proposal to conciliate the need of fuel supply contract ballast to the dynamics of the natural gas sector, and (III) a proposal to conciliate the need for fuel contract ballast to the contracting process of the thermoelectric power in the new energy auctions. These contributions aim at a better integration between the sectors of natural gas and electricity in Brazil, leading to a more efficient use of resources and infrastructure development. (author)

  3. Debunking the myths: Natural gas and SO2 allowance solutions

    1993-01-01

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

    In the early Eighties producers mostly sold their gas to pipeline companies on the basis of relatively long-term, fixed price contrasts. These pipeline companies transported, and partly stored, the natural gas and resold it to local distributors and end consumers. Today's system permits local distributors and end consumers to make supply contracts directly with the producer and separate contracts for the utilisation of transport and storage capacities. These capacity titles are not only available to end consumers, retailers, and wholesalers but can also be traded in secondary markets. (orig./UA) [de

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

    Natural gas has known a rapid development in the French-speaking part of Switzerland and this trend is still continuing. Natural gas represents 13% of the overall energy consumption, which lies significantly above the Swiss average and, in the year 2000, it should reach about 20%. In order to meet the expected growth of consumption, Gaznat has already contracted, under long term agreements, large quantities of natural gas from diversified sources. Underground storage capacities in nearby France have been considerably increased and new gas-pipelines are being built. These pipelines will enable to double the supply capacity of the French-speaking part of Switzerland within the next three years. (orig.) [de

  8. Industrial natural gas supply options in British Columbia

    International Nuclear Information System (INIS)

    1994-01-01

    Information is provided on the availability and cost of natural gas in British Columbia for use by firms interested in establishing gas-intensive industrial facilities in the province. British Columbia has an abundant supply of natural gas, originating mainly from deposits in the westernmost part of the Western Canadian Sedimentary Basin in the northeast part of the province. Recoverable resources in British Columbia are estimated at 1,000-1,400 billion m 3 . Over 200 producers compete to sell natural gas for both domestic and export markets. Gathering, processing, and transmission of the gas is undertaken mainly by the Westcoast Energy pipeline system, and distribution is undertaken by several distribution utilities. At present, all large industrial gas users buy their firm gas requirements directly from gas producers, often using gas marketers or brokers to assist in purchasing. Regulation of the gas industry is performed by the British Columbia Utilities Commission, which sets rules for energy supply contracts, and by the National Energy Board, which sets tolls for gathering, processing, and transporting gas. Factors affecting gas pricing are discussed, with reference to both the wellhead price and the cost of gathering, processing, and transportation. Firm gas costs for two hypothetical industrial loads in British Columbia are illustrated. Potential intensive uses of natural gas in the province are outlined, including power generation, liquefaction for export, manufacturing, production of direct reduced iron, and as petrochemical feedstocks. 5 figs., 2 tabs

  9. Canadian natural gas market: dynamics and pricing

    International Nuclear Information System (INIS)

    2000-01-01

    This publication by the National Energy Board is part of a continuing program of assessing applications for long-term natural gas export licences. The market-based procedure used by the Board is based on the premise that the marketplace will generally operate in a way that will ensure that Canadian requirements for natural gas will be met at fair market prices. The market--based procedure consists of a public hearing and a monitoring component. The monitoring component involves the on-going assessment of Canadian energy markets to provide analyses of major energy commodities on either an individual or integrated commodity basis. This report is the result of the most recent assessment . It identifies factors that affect natural gas prices and describes the functioning of regional markets in Canada. It provides an overview of the energy demand, including recent trends, reviews the North American gas supply and markets, the natural gas pricing dynamics in Canada, and a regional analysis of markets, prices and dynamics in British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec and the Atlantic provinces. In general, demand growth outstripped growth in supply, but natural gas producers throughout North America have been responding to the current high price environment with aggressive drilling programs. The Board anticipates that in time, there will be a supply and demand response and accompanying relief in natural gas prices. A review of the annual weighted average border price paid for Alberta gas indicates that domestic gas users paid less than export customers until 1998, at which point the two prices converged, suggesting that Canadians have had access to natural gas at prices no less favourable than export customers. The influence of electronic trading systems such as NYMEX and AECO-C/NIT have had significant impact on the pricing of natural gas. These systems, by providing timely information to market participants. enables them to manage price

  10. Assignments of rights and obligations under a gas sales contract

    International Nuclear Information System (INIS)

    Kowch, J.R.M.

    1996-01-01

    A general overview of the principles of assignment in a gas sales contract was presented. Assignment is a process wherein the rights or obligations under a contract are transferred from one of the contracting parties to a third party. It is, in other words, the introduction of a new party to the original contractual relationship. Under the rights and obligations of a gas sales contract, the most important right of the seller is to have its gas taken and to be paid. Likewise, the most important obligation of the buyer is to take the gas and pay for it. An assignment by either party has the potential to alter the original expectations of the parties or the basis of which they committed to the contract in the first place. Prior to deregulation and unbundling initiatives, gas sellers and buyers could enter a 20 year sales contract and deal exclusively with each other over the entire 20 year term. Since deregulation, there are more players, and a higher level of corporate acquisitions, divestitures, rationalizations, and restructuring. Today, there are greater chances than ever before that the original party to a contract may change, or that certain rights and obligations may be assigned to a third party and affect the expectations under the contract

    The relationship between the spot price for natural gas for a delivery month and the futures contract price for the same delivery month is examined. The estimated regression equation provides a good summary of the relationship between spot and futures prices for the time period and can also be used to obtain accurate forecasts of spot prices. It appears that the natural gas futures market is inefficient. (author)

    Steffes, D.W.

    1995-01-01

    The monumental discontinuity of the past decade in the natural gas industry was the change of the interstate gas pipeline industry from serving as a merchant function to a common carrier function. The main reason this change could come about was a past strategic error on the part of the interstate pipeline companies. In the early 1980s, they misread the gas supply signals and entered into uneconomical take or pay contracts at unreasonably high prices. This strategic mistake essentially bankrupted all of the pipeline companies. Their submittal to the Federal Energy Regulatory Commission (FERC) forced them to allow open access on their pipelines. The FERC then allowed them to buy their way out of their bad take or pay contracts. The method of pricing natural gas at the wellhead was the other big change. Instead of the major interstate pipeline continuing with a form of mandating area rates, each producer can now deal directly with anyone wanting to purchase the gas. The transportation is available due to these pipelines becoming common carriers. These two discontinuities allowed new paper interstate pipelines to come into existence

    2009-01-01

    Neo-institutional economics (NEI) has long shown that take-or-pay (ToP) long-term contracts provide a robust framework for safeguarding the interests of both upstream and downstream parties in the gas industry. The case of gas trade between Brazil and Bolivia presents an opportunity to re-examine empirically and to review the robust nature of the ToP framework over time. This case reveals that the positions of the contractors actually change giving rise to a veritable lifecycle of the contractual arrangement. Such a contract can be seen to span three successive phases. The first phase of the contract cycle begins when it is signed; allowing the investments to begin. The second phase starts when investments have been completed and the actual trade in gas begins. The third phase of the contract cycle comes when the increasing flow of gas comes close to saturating capacity and the volume levels for downstream market volume have been reached. These three contract phases are thus distinguished by how robust the alignment of the parties' interests is. The added value of the paper is then both empirical and analytical: the case study provides a brand new lifecycle analysis of the performance of ToP long-term contracting into an NEI framework

    The article examines the natural gas markets of the United States, the European Union and the Asia-Pacific region and their regulation and contractual structures. The article's main focus is on the United States natural gas markets. The European Union and Asia-Pacific markets are compared to this more developed market. By comparing the physical and ideological characteristics of, and differences between, the three main international gas markets, the article exposes the limits of regulatory and contractual transplants in this area of law and policy. Each of these markets is unique, which limits the opportunities for modelling certain market institutions on the basis of the more developed markets in the United States. This applies for both the EU and the Asia-Pacific region. - Highlights: • Differences in the physical markets impact regulation. • Regulatory transplants have risks. • The approach in energy policy should be based on “Law-in-Context” approach

    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.

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

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

    International Nuclear Information System (INIS)

    1991-07-01

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

    The latest advancements in the natural gas - NG industry have brought new opportunities for the resource's application, especially in the power industry. On the one hand, rapid growth in demand and falling costs of transportation over long distances, particularly as liquefied natural gas - LNG, should lead to a more integrated NG world market. On the other, the deregulation of electricity markets and the growth of independent power producers - IPPs using NG as a fuel for generating peak load power have increased the demand for more flexible NG supply contracts. These factors have allowed a shift in the timing of investment and contract negotiation in NG market. Traditionally, firms searched for trading partners and signed long-term contracts before investing in infrastructure. In the evolving LNG market, producers invest in infrastructure before they have buyers for all their expected outputs, while buyers undertake investment before having firm contracts for all their expected NG needs. These technological and market changes may foster greater participation of a fully flexible NG power plants in the Brazilian electricity market. Nowadays, thermal power long-term capacity contracts customized and negotiated in the local electricity pool (ACR) require power producer to award guarantees of NG firm supply, substantially increasing their cost. A combination of flexible LNG supply contracts and electricity pool contracts may present a solution to the lack of competitiveness of NG power plants in the Brazilian power industry. (author)

    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.

    1995-01-01

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

  14. An examination of the International Natural Gas Trade

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

  15. The pricing of natural gas in US markets

    Our econometric evidence indicates that changes in natural gas prices are unequal in the long run. Nonetheless, all downstream prices change by at least as much as the average well-head price. Statistically, residential and commercial prices change as much as the city gate price. In the face of persistent shocks, however, market institutions and market dynamics can lead to lengthy periods in which the residential and commercial prices of natural gas adjust less than the wellhead or city gate prices. Electrical and industrial users of natural gas rely heavily on spot supplies and can switch fuels easily. Their ability to switch fuels may be related to the development of a spot market to serve them. Reliance on the spot market may explain why these end users have seen a greater reduction in natural gas prices than have the LDCs over the past seven years. The ability to switch fuels may account for electrical and industrial prices being the source of shocks in their relationships with the wellhead price. It also may explain why prices in these end-sue markets are quick to adjust. Commercial and residential customers cannot switch fuels easily and rely heavily on LDCs for their natural gas. The inability of these end users to switch fuels probably contributes to the reluctance of LDCs to purchase spot supplies of gas. Reliance on contract supplies may explain why the city gate price has not declined as much as electrical and industrial prices of natural gas over the past seven years. Furthermore, the LDCs administer prices in the commercial and residential markets under state regulation

    Distributors of natural gas need to predict future consumption in order to purchase a sufficient supply on contract. Distributors that offer their customers equal payment plans need to predict the consumption of each customer 12 months in advance. Estimates of previous consumption are often used for months when meters are inaccessible, or bimonthly-read meters. Existing methods of predicting natural gas consumption, and a proposed new method for each local region are discussed. The proposed model distinguishes the consumption load factors from summer to other seasons by attempting to adjust them by introducing two parameters. The problem is then reduced to a quadratic programming problem. However, since it is not necessary to use both parameters simultaneously, the problem can be solved with a simple iterative procedure. Results show that the new model can improve the two-equation model to a certain scale. The adjustment to heat load factor can reduce the error of prediction markedly while that to base load factor influences the error marginally. 3 refs., 11 figs., 2 tabs

  17. Mitchell firmly retrenched in natural gas services

    1997-01-01

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

    This quarter`s feature report focuses on natural gas exports to Mexico. OFP invites ideas from the public on future topics dealing with North American natural gas import/export trade. Such suggestions should be left on OFP`s electronic bulletin board. Natural Gas exports to Mexico continued to grow and reached an historic high for the month of June (7.8 Bcf). Two new long-term contracts were activated; Pennsylvania Gas & Water Company began importing 14.7 MMcf per day from TransCanada PipeLines Ltd., and Renaissance Energy (U.S.) Inc. began importing 2.8 MMcf per day from Renaissance Energy Ltd. for resale to Delmarva Power & Light Company. Algerian LNG imports remained stagnant with only one tanker being imported by Pan National Gas Sales, Inc. (Pan National). During the first six months of 1995, data indicates gas imports increased by about 10 percent over the 1994 level (1,418 vs. 1,285 Bcf), with Canadian imports increasing by 14 percent and Algerian imports decreasing by 81 percent. During the same time period, exports increased by 18 percent (83 vs. 70.1 Bcf).

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

    1994-01-01

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

  1. Natural gas price uncertainty and the cost-effectiveness of hedging against low hydropower revenues caused by drought

    Prolonged periods of low reservoir inflows (droughts) significantly reduce a hydropower producer's ability to generate both electricity and revenues. Given the capital intensive nature of the electric power industry, this can impact hydropower producers' ability to pay down outstanding debt, leading to credit rating downgrades, higher interests rates on new debt, and ultimately, greater infrastructure costs. One potential tool for reducing the financial exposure of hydropower producers to drought is hydrologic index insurance, in particular, contracts structured to payout when streamflows drop below a specified level. An ongoing challenge in developing this type of insurance, however, is minimizing contracts' "basis risk," that is, the degree to which contract payouts deviate in timing and/or amount from actual damages experienced by policyholders. In this paper, we show that consideration of year-to-year changes in the value of hydropower (i.e., the cost of replacing it with an alternative energy source during droughts) is critical to reducing contract basis risk. In particular, we find that volatility in the price of natural gas, a key driver of peak electricity prices, can significantly degrade the performance of index insurance unless contracts are designed to explicitly consider natural gas prices when determining payouts. Results show that a combined index whose value is derived from both seasonal streamflows and the spot price of natural gas yields contracts that exhibit both lower basis risk and greater effectiveness in terms of reducing financial exposure.

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

    1990-01-01

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

  4. Today's gas glut and yesterday's contracts: the British Gas predicament

    International Nuclear Information System (INIS)

    Stoppard, M.

    1996-10-01

    Deregulation of the gas and electricity industries has led to a state of pronounced oversupply in the UK gas market. The effects of this oversupply became apparent during the course of 1995 and took two forms. Firstly, there was the emergence of a market for the short-term trading of gas. The price levels in this market collapsed in the first half of 1995 opening up a price gap between ''spot'' and contract gas. Secondly, some contract gas was paid for but was not produced, so that delivery to market was indefinitely postponed: there was a run-up in inventory - or ''take-or-pay'' - gas levels, as a form of keeping supply off the market. Oversupply has exerted great pressure on a number of market participants throughout the gas chain who remain locked into purchase agreements for volumes which have no market outlet, and at prices above market levels. The rally in spot price levels experienced since the second quarter of 1996 has eased pressure within the market but has not removed the fundamental strains. The market is expected to remain in oversupply at least up to the end of 1998. Keen price competition may not clear the market even at discount prices, so that shut-in of production capacity is likely. The consequent build-up in take-or-pay levels will continue through the period, although at steadily declining rates, and there is little scope prior to 1999 for the industry as a whole to offload this inventory gas on the market.

    As never before in the last year we have suffered the increases in the cost of the natural gas. For those who are not aware, the prices have gone from 2.48 dollars per million BTU a year ago to 9.57 last month. The truth is that we are facing a true world-wide energy crisis. From one year to date the prices of all the energy sources have increased an average superior to 30%, including increases in Diesel oil, LP Gas, Natural Gas, Turbine fuel. The causes are many and very varied, from efficiency decisions, as in the case of the electrical Generation that has chosen to incline definitively to the natural gas, confusing de-regulations as in the case of California, increases of demand beyond the anticipated by economic activity, changes of consumption pattern, etc.. This demonstrates the well focussed and the opportunity of this Seminar, since there is no doubt that it has become imperative a single and efficient criterium on this so limited resource. In Mexico, the situation is very similar. Recently a measurement has been implemented that tries to palliate the conjunctural effects of this crisis and PEMEX has put to the disposition of the users a contract at fixed price, for three years and by a specific amount.

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

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

    The use of vehicular natural gas (VNG) was initiated in Brazil in he 80's seeking the replacement of diesel in heavy vehicles due to the oil crisis. In this season PETROBRAS participated, along with other companies, in the development of conversion technologies for replacement part of the diesel by natural gas through systems known as diesel-gas. Were made works to development bank of tests of engines and field tests on some bus companies, verifying if there are technical and economic viability of such conversion. Due to factors such as small mesh distribution of natural gas in Brazil, lack of infrastructure of technical support suitable for conversions and lack of culture in the use of natural gas, the program not progressed and experience was interrupted. Other experiments were conducted in Brazil with the use of engines dedicated to natural gas (Otto cycle) developed and manufactured in the country for use in urban buses. Currently there is a scenario favorable to the return of use of natural gas in weighed vehicles by the following factors: 1) increase the mesh distribution of VNG due to the high growth of the fleet light vehicles to VNG in the country, solving part of the problems of logistics; 2) pressure from environmental agencies by values of emissions of particles and gases ever less pollutants in urban centers; 3) excess supply of natural gas in the domestic market due to new discoveries in Brazil, contracts for the import of natural gas signed with Bolivia and low demand for current industrial consumption of gas; 4) need to replace the import of diesel, which weighs in trade of the country. This paper will be presented some experiences with the technology of diesel-gas and the engine dedicated the VNG in weighed vehicles in Brazil. Also some recommendations will be made to increase and spread the use of these technologies, aiming to increase the replacement of diesel by vehicular natural gas in weighed vehicles. (author)

  12. Long term contracts in portfolios of core LDC gas supply

    International Nuclear Information System (INIS)

    John, F.E.

    1992-01-01

    This paper recommends that local distribution companies (LDCs) should use a portfolio approach for their gas supply strategy. The author recommends that LDCs not rely on spot supplies to meet the peak needs of the core residential and commercial markets. He recommends that a secure supply through long-term contracts are better sources than spot or even intermediate term suppliers. The paper provides a brief outline format of the advantages to the use of a portfolio approach which include the rapid restructuring of the market, general changes in the market, and general market performance. By maintaining a portfolio, a list of available natural gas suppliers is always available. This portfolio also acts to compare pricing between short, medium, and long-term pricing for the LDCs

    The Ministry of Industry and Energy evaluates which of the natural gas fields to be selected for covering the gas supply based on contract obligations. The evaluation aims at giving a total valuation of possible development solutions on the Norwegian continental shelf. Actual solutions are based on fields located in the Haltenbanken area or in the North Sea. The present report relates to a study analysing the consequences on how the employment and regional conditions are influencing the socio-economic and real economic factors by alternative solutions of contract allocations. 38 refs., 9 figs., 7 tabs.

  14. The World gas model. A multi-period mixed complementarity model for the global natural gas market

    2010-01-01

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

    The 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)

  16. Investment risk aspects of new gas contracts in the UKCS

    International Nuclear Information System (INIS)

    Kemp, A.G.; Stephen, L.

    1996-01-01

    The market faced by gas producers in the UKCS has changed considerably since 1990. Producers contemplating the development of new fields are today highly unlikely to attain life-of-field depletion contracts for their gas. They may not even be able to negotiate long-term take or pay contracts for a high proportion of their reserves. Today's producers face not only volume risk, in the sense that they may be unable to attain contracts for all their reserves, but they are exposed to price risks to a greater extent than they have been in the past. The aim of this study is to consider the degree of economic risk faced by gas producers in this new market situation with emphasis on volume and price risks. Emphasis is given to the position of an investor contemplating the development of a new field in circumstances where firm contract(s) are available for only some of the potential output of the field, and assessments of the chances of obtaining further contracts have to be made and set alongside the effects of simply selling gas on the spot market. The emphasis is on elucidating the risk:reward situation facing investors in such situations. The underlying objective of the investor is taken to be the maximisation of his returns (expressed in terms of net present value (NPV)). Attention in the risk analysis is given to upside potential and downside risks. (author)

  20. Natural gas purchasing

    International Nuclear Information System (INIS)

    Freedenthal, C.

    1993-01-01

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

    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

    This paper gives informations on petroleum and natural gas industry, petroleum market and prices, trade and contracts, prospection and production. The possible return of Iraq on the petroleum market has an influence on petroleum prices. In Algeria, Sonatrach will deliver 2.5 milliards m 3 to Portugal through the Maghreb-Europe gas pipeline. In Tunisia, a petroleum exploration permit has been attributed to Atlantic Richfield Company and Miskar natural gas field would come into production in 1995. In Saudi Arabia, Saudi Aramco has bought all the petroleum refining and distribution interests of the Saudi Arabian Marketing and Refining Company and Petromin Company and now Saudi Aramco is become a national integrated petroleum company. Petroleum exploration is going on in Caspian sea (Iran), six new oil fields have come into production in the Deir ez-Zor and Ash Sham permits (Syria) and petroleum exploration contracts have been signed in Angola, Nigeria and Zaire. In Egypt, the growth of natural gas consumption gives an indication upon the future growing deficit

    Created by Law 9.478/97 (Law of Oil), the Agencia Nacional do Petroleo, Gas Natural e Biocombustiveis (ANP) has, among others, the purpose of laborating edicts and promoting public tenders to give concession to exploration, development and production of oil and natural gas, celebrating the future contracts and monitoring its execution. This procedure, however, has strong differences in comparison to the classical law 8.666/93 - the general law of public tenders of Brazil -, given the specificities of petroleum and gas natural industry. Based on the mitigation of the concept of free competition, ANP made, recently, use of clauses that restrict the offers to the winning bidders that participate in ANP's public tenders. The restrictive measure taken by the Regulatory Agency is constitutional, in order that it, indeed, develops the market and prevents the concentration of a single agent in a particular economic exploratory block, accomplishing the real free competition.

  6. Accounting for fuel price risk when comparing renewable to gas-fired generation: the role of forward natural gas prices

    International Nuclear Information System (INIS)

    Bolinger, Mark; Wiser, Ryan; Golove, William

    2006-01-01

    Unlike natural gas-fired generation, renewable generation (e.g., from wind, solar, and geothermal power) is largely immune to fuel price risk. If ratepayers are rational and value long-term price stability, then-contrary to common practice-any comparison of the levelized cost of renewable to gas-fired generation should be based on a hedged gas price input, rather than an uncertain gas price forecast. This paper compares natural gas prices that can be locked in through futures, swaps, and physical supply contracts to contemporaneous long-term forecasts of spot gas prices. We find that from 2000 to 2003, forward gas prices for terms of 2-10 years have been considerably higher than most contemporaneous long-term gas price forecasts. This difference is striking, and implies that comparisons between renewable and gas-fired generation based on these forecasts over this period have arguably yielded results that are biased in favor of gas-fired generation

  7. Tariffs for natural gas, heat, electricity and cogeneration in 1998

    International Nuclear Information System (INIS)

    1998-03-01

    The rate of return of the combined generation of heat and power is not only determined by the capital expenditures and the costs of maintenance, control, management and insurance, but also by the fuel costs of the cogeneration installation and the avoided fuel costs in case of separated heat production, the avoided/saved costs of electricity purchase, and the compensation for possible supply to the public grid (sellback). This brochure aims at providing information about the structure of natural gas and electricity tariffs to be able to determine the three last-mentioned expenditures. First, attention is paid to the tariffs of natural gas for large-scale consumers, the tariff for cogeneration and horticulture, and natural gas supply contracts. Next, the structure of the electricity tariffs is dealt with in detail, discussing the accounting system within the electric power sector, the tariffs and compensations for large-scale consumers and specific large-scale consumers, electricity sellback tariffs, and compensations for reserve capacity. Also attention will be paid to tariffs for electricity transport. Finally, several taxes, excises and levies that have a direct or indirect impact on natural gas tariffs, are discussed. 9 refs

  9. Canadian natural gas market: dynamics and pricing -- an energy market assessment

    International Nuclear Information System (INIS)

    2000-11-01

    This publication is part of the Energy Market Assessment Program of the National Energy Board. It focuses on identifying factors that affect natural gas prices and describe the current functioning of domestic regional markets in British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec and in the Atlantic provinces.The report emphasizes the growth in demand for natural gas throughout North America, and the aggressive response by producers to the current high price environment with increased drilling programs. The report also predicts a supply and demand adjustment over time, and an accompanying relief in natural gas prices, although the Board is not able to predict with certainty any movements in commodity markets. The Board's findings indicate that domestic users of natural gas paid less than export customers until 1998, at which point the two prices have converged. The end result of the convergence was that Canadians have had access to natural gas under terms and conditions which were no less favourable than those in effect for export customers. The influence of electronic trading systems is reviewed, noting that spot markets and futures markets such as the NYMEX and AECO-C/NIT have had a significant impact on the pricing of natural gas, mostly by allowing market participants to manage price volatility by forward contracting. 1 tab., 42 figs., 1 glossary

    The purpose of this paper is to describe the benefits and uses of the natural gas futures market. The first section addresses the question of why there are futures in the first place, gives a brief history of energy futures complex, and discusses the basic characteristics of a futures market. The second half of the paper focuses specifically on the natural gas contract and presents specific ways that futures may be used by companies as part of a commodity risk management program. As discussed, the overall objective is a shifting of commodity exposure away from the corporation in an effort to enhance rates of return, as well as smooth out or normalize earnings

    2001-07-01

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

    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

    1979-08-20

    Sohio has agreed to sell Vertical Bar3: 2 trillion cu ft of its Prudhoe Bay gas to Northern Natural Gas Co. for delivery at a rate of 170 million cu ft/day when the proposed Alaska Highway gas pipeline is completed. With the exception of approx. 4 trillion cu ft of Sohio's reserves committed to Columbia Gas System Inc., the agreement accounts for the sale of all the 26.5-27 trillion cu ft of Prudhoe Bay reserves. The contract, which is subject to approval of the U.S. Federal Energy Regulatory Commission, allows Alaska to take its one-eighth royalty share of the gas in kind or cash. Columbia Gas is the only firm planning to purchase Prudhoe Bay gas that is not participating as an equity owner in the pipeline project. According to a Columbia spokesman, it is still uncertain whether the proposed gas pipeline will be built; and the fact that Columbia has not yet signed a final agreement with Sohio does not indicate any decreasing interest in Prudhoe Bay gas.

    2008-01-01

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

    Research results for discharges at current amplitudes of 0.5-1.6 MA and current rise rate of ∼10 10 A/s are presented. The discharge is performed in the hydrogen environment at the initial pressure of 5-35 MPa. Initiation is implemented by a wire explosion. The time length of the first half-period of the discharge current is 70-150 μs. Under such conditions, discharge channel contraction is observed; the contraction is followed by soft x-ray radiation. The phenomena are discussed, which are determined by high density of the gas surrounding the discharge channel. These phenomena are increase of the current critical value, where the channel contraction begins and growth of temperature in the axis region of the channel, where the initial density of the gas increases.

    A decision support model is presented which will give utilities the support tools to manage the purchasing of natural gas supplies in the most cost effective manner without reducing winter safety stocks to below minimum levels. In Business As Usual (BAU) purchasing quantities vary with the daily forecasts. With Material Requirements Planning (MRP) and Linear Programming (LP), two types of factors are used: seasonal weather and decision rule. Under current practices, BAU simulation uses the least expensive gas source first, then adding successively more expensive sources. Material Requirements Planning is a production planning technique which uses a parent item master production schedule to determine time phased requirements for component points. Where the MPS is the aggregate gas demand forecasts for the contract year. This satisfies daily demand with least expensive gas and uses more expensive when necessary with automatic computation of available-to-promise (ATP) gas a dispacher knows daily when extra gas supplies may be ATP. Linear Programming is a mathematical algorithm used to determine optimal allocations of scarce resources to achieve a desired result. The LP model determines optimal daily gas purchase decisions with respect to supply cost minimization. Using these models, it appears possible to raise gross income margins 6 to 10% with minimal additions of customers and no new gas supply.

    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

    2015-02-01

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

    In Europe, the process of creating a single energy market is under way. The 1998 Gas Directive established an important date for the European gas industry. On 10 August 1998, ''Directive 98/30/EC of the European Parliament and of the Council of 22 June 1998 concerning common rules for the internal market in natural gas'' came into force. It had to be transposed into national law by the EU member states within two years, i.e. by 10 August 2000. The Directive is a cornerstone in establishing a competitive gas market in the European Union. It is the outcome of several years of negotiations and can be regarded as a compromise between the various interests. On the whole, it leaves EU member states with sufficient scope for adequately taking account of national characteristics in keeping with the principle of subsidiarity. The process of transposing the Gas Directive into the national law of individual EU member states is being closely followed by the European Commission. While acknowledging all the progress made in the single market process, the Commission still detects shortcomings in the implementation of the Gas Directive on the road to an actual single market. This is seen as a justification for new initiatives and intervention, even though the new political framework for the gas industry has not yet been tested in practice and been able to prove itself on a broad scale for any length of time. In the debate on liberalisation, tried-and-tested instruments of secure and market-oriented gas supply on the European continent long-term supply contracts with take-or-pay clauses and competitive oil-indexed gas prices have also come under scrutiny. However, even under the conditions of liberalisation, security of supply has to be achieved mainly by a balanced mix of supply sources and by long-term supply contracts, including competitive pricing as ensured by so-called oil indexing. In the further liberalisation of west European gas industries, it will be essential to ensure

  7. Application of Fiscal Incentives for Development of East Natuna Gas Field for Long-Term National Natural Gas Demand

    Full Text Available East Natuna gas field, which has proven reserves of 46 trillion cubic feet, is projected to meet long-term natural gas needs. However, CO2-content of the gas reserves reaches 71%, leading to expensive development costs. This research investigates the feasibility of the field based on several fiscal incentives. Firstly, gas supply-demand until year 2040 was analyzed. Then, based on the analysis, the field was developed using high CO2 gas separation technology to produce gas of 1300 MMSCFD in 2023, 2600 MMSCFD in 2031, and 3900 MMSCFD in 2039. Finally, the economic feasibility was assessed using cash flow analysis in accordance with Indonesia’s production sharing contract scheme. The results show that the supply-demand gap continues to increase and thus the development is urgently needed. The development cost is estimated around US$ 27.59 billion. The gas selling prices are assumed at US$ 8/MMBTU for wellhead, US$ 11/MMBTU for pipelines, and US$ 11/MMBTU for LNG. To achieve minimum IRR value of 12%, the government needs to offer incentives of 30-year contract period, profit sharing of 55%: 45%, first tranche petroleum to 10%, and tax holiday of 10 years. Toll fee for Natuna-Cirebon pipeline is US$ 2.3/MMBTU at IRR of 12.6%.

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

    The France has got only a few natural gas resources, which will disappear in 2013. Thus it essentially depends on international markets for its supplying. Most of the supplying contracts are long dated contracts indexed on the petroleum products. Since 2005 the pressures of the petroleum and gas markets produce tariffs increases. Facing this situation the Government implemented a tariff fixation policy. (A.L.B.)

    This work aims to identify actions that can be implemented to increase the energy efficiency of processes involved in the value chain of natural gas, specifically in the process of heating in existing city-gates of transporting natural gas Brazilians plants. The goal is increase supply of gas in Brazil. The main function of city-gates is to deliver the natural gas in contract terms (flow, pressure, temperature and quality). The main issue related to the consumption of natural gas fuel in city-gates is related to the operation (set-up and control) of natural gas combustion, in other words, depends on how the heating system is adjusted dynamically to burn, efficiently, the exact amount of gas required by this system, depending on temperature, pressure, temperature, quality and flow of natural gas at the 'city-gates'. The main objective of this work is to present a study on alternatives at design, set-up and control of natural gas city-gates (transport) in Brazil, aiming to increase the energy efficiency of this facility, and thus contributing to the growth in supply of natural gas available to the market.

    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

    The transportation of large quantities of natural gas through long distances has been done more frequently by Liquefied Natural Gas (LNG). The increase of natural gas demand and the distance of major reserves, allied to technological improvements and cost reduction through LNG supply chain, have triggered the expressive increase of LNG world market This paper tries to evaluate the influence that LNG should cause on natural gas world market dynamic, analyzing the tendency of gas to become a world commodity, creating international price references, like oil and its derivates. For this, are shown data as natural gas world reserves, the participation of LNG in natural gas world market and their increase. Furthermore, will be analyzed the interaction between major natural gas reserves and their access to major markets, still considering scheduled LNG projects, the following impacts from their implementation and price arbitrage that should be provoked on natural gas markets.

    This paper reviews and compares the advantages and disadvantages that electric power generators have in generating electricity from a variety of fuel sources. It then goes on to emphasize the use of natural gas and how it can become more competitive in the electric generation field. The paper is based primarily on experiences by the author during his employment with the New England Electric System (NEES). The author reviews the source of electricity for this utility and describes the percentages of each fuel source. It then goes on to specifically discuss the planned natural gas-fired projects in the utility system. The paper outlines the NEES strategy of diversification with respect to gas suppliers and describes the important considerations it used when planning for electric generation with gas. These include determining pressure requirements needed by the gas distribution system when the gas-generators come on-line; determining the placement of the generators within the overall system (i.e. peak load facilities, base load facilities, etc.); contracting flexibility because of the need to vary the amount of gas taken; and the ability to manage pipeline capacity and gas supplies when they are not needed

    This second report on the operation of French wholesale electricity and natural gas markets deals with CRE wholesale market surveillance activities. It follows on from the different work undertaken or announced in the first surveillance report and in the proceedings of the CRE deliberation held on the 8 January 2009. It capitalizes on the experience gained in this area since the Law of the 7 December 2006 gave the CRE market surveillance powers. It is also based on feedback from discussions and interaction with the different stakeholders, through the public consultations held by CRE in 2008 and 2009. market surveillance applies to: - electricity and gas, - bilateral transactions, trading on exchanges and cross-border transactions, - all maturities, from short-term markets to long-term contracts, - all French wholesale market counter-parties, whatever nationality they may have, - contracts for physical delivery, as well as to financial products. The Law also allows extensive surveillance of market participants' behaviour, in that the CRE can oversee not only transactions between operators but also their bids and the correspondence between the prices charged and the position of each operator. In order to address these different subjects, the electricity and gas sections of this report are divided into four main chapters dealing with the development of trading, wholesale market price trends, the fundamentals (generation, infrastructures) and, finally, the analysis of electricity transactions and the supply of alternative gas operators. Contents: A - Methodology notice, Introduction, Summary of the report; B - Section 1 - Wholesale electricity markets: The development of the main wholesale market segments, Monitoring of price formation in France in terms of fundamentals and in comparison with the main interconnected European markets, Analysis and transparency of generation, The analysis of transactions; C - Section 2 - Wholesale natural gas markets: The

    In the last 20 years, several countries have undergone to structural reforms in the gas sector, to increase the economic efficiency through the introduction of competition. This work proposes a framework to stimulate the development of competition in the gas sector in Brazil, based on a market forecast, the international experience and the characteristics of the market, structure and regulation in Brazil; the impacts of this framework in the market are also analyzed. According to the market forecasting, there will be a likely surplus of natural gas in Brazil. This surplus, allied with retail trading competition to be introduced in the states of Sao Paulo and Rio de Janeiro, together with a sound regulation that promote open access and transparency, moreover a regulated transmission, distribution and storage, may help to stimulate competition. If the framework is implemented, it would probably help the creation a wholesale and a retail gas market; stimulating risk management tools, i.e. derivative instruments; promoting a shift from long-term to short-term contracts between LDC's and shippers; creating a spot and future markets; and promoting a move towards spot and futures gas price indexing in mid- and long-term supply contracts. Competition would probably bring end-user prices down, as it happened in other countries that faced deregulation process. (author)

    1996-01-01

    In this communication we discuss some key features of the natural gas cash and futures markets for natural gas in the USA. We also summarize some important and interesting problems in these markets. For example, the market does not appear to be informationally efficient throughout the USA. This lack of efficiency has been addressed by the establishment of a second futures contract market. There is also a very active unregulated derivatives market in which options and swaps are bought and sold. Although the market has changed significantly to better respond to changes in market conditions there are still problems in the way that pipeline space is allocated by pipeline companies, who still own the pipe, to those companies that have rights to this space. There are also problems in that prices for gas and transport are not transparent to many buyers and sellers. Moreover, there are also important idiosyncracies and industry practices that impede progress. None the less, the different parts of the industry with different interests and expertise and the regulatory authority continue to work at crafting rules to improve business behaviour and performance.

    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

    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.

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

    1991-09-01

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

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

  12. Natural gas is more than gas power plants

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

    The primary objective of the Infield Reserve Growth/Secondary Natural Gas Recovery (SGR) project is to develop, test, and verify technologies and methodologies with near- to midterm potential for maximizing the recovery of natural gasfrom conventional reservoirs in known fields. Additional technical and technology transfer objectives of the SGR project include: To establish how depositional and diagenetic heterogeneities in reservoirs of conventional permeability cause reservoir compartmentalization and, hence, incomplete recovery of natural gas. To document examples of reserve growth occurrence and potential from fluvial and deltaic sandstones of the Texas gulf coast basin as a natural laboratory for developing concepts and testing applications to find secondary gas. To demonstrate how the integration of geology, reservoir engineering, geophysics, and well log analysis/petrophysics leads to strategic recompletion and well placement opportunities for reserve growth in mature fields. To transfer project results to a wide array of natural gas producers, not just as field case studies, but as conceptual models of how heterogeneities determine natural gas flow units and how to recognize the geologic and engineering clues that operators can use in a cost-effective manner to identify incremental, or secondary, gas.

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

    The General Auditor in the Netherlands studied the natural gas policy in the Netherlands, as has been executed in the past decades, in the period 1997-1999. The purpose of the study is to inform the Dutch parliament on the planning and the backgrounds of the natural gas policy and on the policy risks with respect to the benefits for the Dutch State, taking into account the developments in the policy environment. The final conclusion is that the proposed liberalization of the national natural gas market will result in a considerable deprivation of income for the State in case the benefit policy is not adjusted. This report includes a reaction of the Dutch Minister of Economic Affairs and an afterword of the General Auditor. In the appendix an outline is given of the natural gas policy

  17. 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

    An extensive North American pipeline grid that physically integrates individual natural-gas markets, in conjunction with economic ties binding the California markets to those at Henry Hub, Louisiana and the New York mercantile exchange via an array of financial instruments, suggests that the spot prices at Henry Hub will impact those in California. We verify the suggestion via a partial-adjustment regression model, thus affirming that California traders can exploit the cross-hedging opportunities made available to them via market integration with Henry Hub, and that they can accurately forecast the price they will have to pay to meet future demand based solely on the price of futures at Henry Hub and the price of a California natural-gas basis swaps contract.

    The aim of this study is to map the technical, economic and organizational options and limitations of feeding biogas back into the natural gas grid by means of regional co-digestion. Emphasis is put on feeding back into the natural gas grid, analogous to a comparable situation in a number of landfill gas projects. This report first provides insight into the energetic potential of co-digestion. Next several landfill gas projects are examined that feed back into the natural gas grid. After that the political and policy-related issues and preconditions for feeding back biogas from co-digestion are discussed, including the technical and economic aspects. Finally, a picture is painted of the future potential of green gas. [mk] [nl

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

    2005-01-01

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

    1999-06-01

    This thesis presents an approach for financial modelling of natural gas in which connections between locations are incorporated and the complexities of forward curves in natural gas are considered. Apart from electricity, natural gas is the most volatile commodity traded. Its price is often dependent on the weather and price shocks can be felt across several geographic locations. This modelling approach incorporates multiple risk factors that correspond to various locations. One of the objectives was to determine if the model could be used for closed-form option prices. It was suggested that an adequate model for natural gas must consider 3 statistical properties: volatility term structure, backwardation and contango, and stochastic basis. Data from gas forward prices at Chicago, NYMEX and AECO were empirically tested to better understand these 3 statistical properties at each location and to verify if the proposed model truly incorporates these properties. In addition, this study examined the time series property of the difference of two locations (the basis) and determines that these empirical properties are consistent with the model properties. Closed-form option solutions were also developed for call options of forward contracts and call options on forward basis. The options were calibrated and compared to other models. The proposed model is capable of pricing options, but the prices derived did not pass the test of economic reasonableness. However, the model was able to capture the effect of transportation as well as aspects of seasonality which is a benefit over other existing models. It was determined that modifications will be needed regarding the estimation of the convenience yields. 57 refs., 2 tabs., 7 figs., 1 append

    Wilding, Bruce M; Turner, Terry D

    2014-12-02

    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.

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

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

  12. Natural gas productive capacity for the lower 48 states, 1982--1993

    International Nuclear Information System (INIS)

    1993-01-01

    The purpose of this report is to analyze monthly natural gas wellhead productive capacity and project this capacity for 1992 and 1993, based upon historical production data through 1991. Productive capacity is the volume of gas that can be produced from a well, reservoir, or field during a given period of time against a certain wellhead back-pressure under actual reservoir conditions excluding restrictions imposed by pipeline capacity, contracts, or regulatory bodies. For decades, natural gas supplies and productive capacity have been adequate, although in the 1970's the capacity surplus was small because of market structure (both interstate and intrastate), increasing demand, and insufficient drilling. In the early 1980's, lower demand together with increased drilling led to a large surplus of natural gas capacity. After 1986, this large surplus began to decline as demand for gas increased, gas prices dropped, and gas well completions dropped sharply. In late December 1989, this surplus decline, accompanied by exceptionally high demand and temporary weather-related production losses, led to concerns about the adequacy of monthly productive capacity for natural gas. This study indicates that monthly productive capacity will drop sharply during the 1992-1993 period. In the low gas price, low drilling case, gas productive capacity and estimated production demand will be roughly equal in December 1993. In base and high drilling cases, monthly productive capacity should be able to meet normal production demands through 1993 in the lower 48 States. Exceptionally high peak-day or peak-week production demand might not be met because of physical limitations. Beyond 1993, 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

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

    In the last 20 years, several countries have undergone to structural reforms in the gas sector, to increase the economic efficiency through the introduction of competition. This work proposes a framework to stimulate the development of competition in the gas sector in Brazil, based on a market forecast, the international experience and the characteristics of the market, structure and regulation in Brazil; the impacts of this framework in the market are also analyzed. According to the market forecasting, there will be a likely surplus of natural gas in Brazil. This surplus, allied with retail trading competition to be introduced in the states of Sao Paulo and Rio de Janeiro, together with a sound regulation that promote open access and transparency, moreover a regulated transmission, distribution and storage, may help to stimulate competition. If the framework is implemented, it would probably help the creation a wholesale and a retail gas market; stimulating risk management tools, i.e. derivative instruments; promoting a shift from long-term to short-term contracts between LDC's and shippers; creating a spot and future markets; and promoting a move towards spot and futures gas price indexing in mid- and long-term supply contracts. Competition would probably bring end-user prices down, as it happened in other countries that faced deregulation process. (author)

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

  20. Natural gas prices

    International Nuclear Information System (INIS)

    Johnson, W.A.

    1990-01-01

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

    Illustrated by tables and graphs, this publication presents and comments data related to primary consumption of natural gas in France (increase in 2015), national production (still marginal), the evolution of imports and re-exports (a decrease of imports more than balanced by the strong decrease of re-exports), the origin of supplies (a rather diversified supply still dominated by Norway and still attractive short-term contracts), stocks, the evolution of consumption in relationship with climate and use of gas-fired plants (evolution of consumption since 1970, supplies to the different sectors), and the evolution of supplies to the different regions

  2. The duty to negotiate in good faith and the enforceability of short-term natural gas clauses in production sharing agreements

    1997-01-01

    The exploitation of natural gas resources not associated with oil production, poses legal and ethical problems for some countries. This document examines various international oil contracts, especially Production Sharing Agreements (PSA), to establish how short-term gas provisions can be exploited. In particular the issue of breaching a PSA by failing to negotiate in good faith on such a project is debated, showing how clearly this duty falls on the government party. International oil companies are urged to create contracts which allow them to enforce short-term PSA gas clauses. (UK)

  8. Natural gas vehicles in Italy

    International Nuclear Information System (INIS)

    Mariani, F.

    1991-01-01

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

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

    International Nuclear Information System (INIS)

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

    2013-01-01

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

  15. 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

    An overview of the Bulgarian natural gas industry is presented. The starting point was the discovery of the indigenous Chiren gas-field in 1967. The first agreement with the ex-USSR for supply of natural gas and construction of main pipelines was signed in 1968. The state gas company BULGARGAZ is responsible for transportation, storage, distribution, processing and marketing of the gas to over 150 industrial companies in the country, as well as for the transportation services to gas importers in neighboring Turkey. The GAZSTROJMONTAZH company accomplish the construction of the local and transit pipelines to Turkey and Greece, as well as of some objects in Iran, Syria, Ukraine and Germany. In the past 20 years, 87890 million m 3 natural gas from Russia are supplied and 846 million m 3 - from domestic sources. The share of natural gas in the overall energy balance is 13.6% for 1992. The restructuring and further development of gas industry require to take into account some factors as: security in supply; investments for technical assurance; pricing policy for natural gas; development of private business. Some administrative problems are also mentioned. 2 tabs., 1 fig

    This report summarizes the methodology and models developed to assess the risk to energy delivery from the potential loss of underground gas storage (UGS) facilities located within the United States. The U.S. has a total of 418 existing storage fields, of which 390 are currently active. The models estimate the impacts of a disruption of each of the active UGS facilities on their owners/operators, including (1) local distribution companies (LDCs), (2) directly connected transporting pipelines and thus on the customers in downstream States, and (3) third-party entities and thus on contracted customers expecting the gas shipment. Impacts are measured across all natural gas customer classes. For the electric sector, impacts are quantified in terms of natural gas-fired electric generation capacity potentially affected from the loss of a UGS facility. For the purpose of calculating the overall supply risk, the overall consequence of the disruption of an UGS facility across all customer classes is expressed in terms of the number of expected equivalent residential customer outages per year, which combines the unit business interruption cost per customer class and the estimated number of affected natural gas customers with estimated probabilities of UGS disruptions. All models and analyses are based on publicly available data. The report presents a set of findings and recommendations in terms of data, further analyses, regulatory requirements and standards, and needs to improve gas/electric industry coordination for electric reliability.

  18. Recent developments in the natural gas regulatory arena

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

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

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

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

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

  7. 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

  8. Natural Gas Regulation

    International Nuclear Information System (INIS)

    1995-01-01

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

  9. Strategies for contracting gas storage and hub services

    International Nuclear Information System (INIS)

    Auld, J.

    1996-01-01

    The many efficiencies that can be gained by the natural gas industry in effectively using storage, were demonstrated. The circumstances under which the natural gas industry uses storage and how Market Centres or Hub Services can be strategically used in offering companies the highest flexibility in a tough marketplace, were explained. For example, in North America, storage played an important role during the winter of 95/96, which will be remembered for its extreme cold. That year provided the first true opportunity to test the natural gas delivery system since deregulation in 1985. The fact that natural gas supplies continued to be delivered throughout the entire winter was attributed to the use of stored gas held in reserves to meet the severe demand. The companies that did well, relied on storage and also on the services offered by Hub Services which increased margins for all players in the natural gas industry. Using storage, companies can ensure that field deliveries of gas are kept constant by having storage facilities absorb the swings in market demand. The companies that learn to use storage effectively can create competitive edges over their competition and provide more value to their customers. The three main categories of hub services were also described. These are parking (interruptible storage), gas loans (stored gas can be offered to customers on a term basis for low daily rates), and title exchange (the transfer of gas between buyer and seller). The strategic use of parking, loaned gas, title exchange, direct connections, and InterHub Services can provide customers even greater benefits than are provided by storage-based services. 6 figs

  11. Risk premium in the UK natural gas forward market

    International Nuclear Information System (INIS)

    Hobaek Haff, Ingrid; Lindqvist, Ola; Loeland, Anders

    2008-01-01

    This report investigates the UK natural gas market, and tests whether it is a fair-game efficient forward market, using forward contracts ranging from one to five months time to delivery. The forward and spot price series are separately non-stationary, but cointegrated. Furthermore, the forward prices are biased predictors of both the future spot and the 1-month-ahead forward price. The risk premium on the forward prices is positive, as opposed to the US gas market, where the risk premium was found to be negative in similar work. Moreover, the analysis reveals that the storage model is an incomplete model for the relationship between the spot and forward prices. However, storage has a clear effect on this relationship, an effect that appears to be non-linear. (author)

  12. 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.

    1998-01-01

    The outlook for U.S. natural gas supply and demand in the residential, commercial, industrial/cogeneration, electricity and transportation sectors for 1995, 2000, 2005, 2010, and 2015 was presented. A summary of gas well completions from 1990 to 1997 was also provided. The Canadian natural gas resource was estimated at 184 trillion cubic feet. In 1996, Canada produced 5.6 trillion cubic feet of natural gas, half of which was exported to the U.S. New pipeline projects have been proposed to transport natural gas from eastern offshore areas and the Western Canadian Sedimentary Basin. A table representing U.S. and Canada gas trade from 1990 to 1997 and a map of proposed Canadian and U.S. natural gas pipeline routes were also included. Looking into the future, this speaker predicted continued volatility in natural gas prices. 9 tabs., 9 figs

    2005-01-01

    The North American natural gas market has seen significant changes recently due to deregulation and restructuring. For example, third party marketers can contract for transportation and purchase of gas to sell to end-users. While the intent was a more competitive market, the potential for market power exists. We analyze this market using a linear complementarity equilibrium model including producers, storage and peak gas operators, third party marketers and four end-use sectors. The marketers are depicted as Nash-Cournot players determining supply to meet end-use consumption, all other players are in perfect competition. Results based on National Petroleum Council scenarios are presented. (Author)

  15. The French wholesale electricity and natural gas markets. 2009-2010 Report

    International Nuclear Information System (INIS)

    2010-10-01

    This report on the operation of French wholesale electricity and natural gas markets deals with CRE wholesale market surveillance activities. It capitalizes on the experience gained in this area since the Law of the 7 December 2006 gave the CRE market surveillance powers. It is also based on feedback from discussions and interaction with the different stakeholders through public consultations. Market surveillance applies to: - electricity and gas, - bilateral transactions, trading on exchanges and cross-border transactions, - all maturities, from short-term markets to long-term contracts, - all French wholesale market counter-parties, whatever nationality they may have, - contracts for physical delivery, as well as to financial products. The Law also allows extensive surveillance of market participants' behaviour, in that the CRE can oversee not only transactions between operators but also their bids and the correspondence between the prices charged and the position of each operator. In order to address these different subjects, the electricity and gas sections of this report are divided into four main chapters dealing with the development of trading, wholesale market price trends, the fundamentals (generation, infrastructures) and, finally, the analysis of electricity transactions and the supply of alternative gas operators. Contents: A - Introduction, Summary of the report; B - Section 1 - The wholesale electricity markets: The development of the main segments of the wholesale market, Electricity prices, Analysis of generation and its transparency, Analysis of transactions; C - Section 2 - The wholesale gas markets: The development of gas trading, Gas prices, The gas infrastructures, The supply of players/new entrants; D - Section 3 - Appendices: Glossary, Index to graphs, Index to tables, Index to boxes

  16. Natural gas and crude oil

    Valais, M.R.

    1991-01-01

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

  17. Dynamic Contraction of the Positive Column of a Self-Sustained Glow Discharge in Molecular Gas Flow

    Shneider, Mikhail

    2014-10-01

    Contraction of the gas discharge, when current contracts from a significant volume of weakly ionized plasma into a thin arc channel, was attracted attention of scientists for more than a century. Studies of the contraction (also called constriction) mechanisms, besides carrying interesting science, are of practical importance, especially when contraction should be prevented. A set of time-dependent two-dimensional equations for the non-equilibrium weakly-ionized nitrogen/ air plasma is formulated. The process is described by a set of time-dependent continuity equations for the electrons, positive and negative ions; gas and vibrational temperature; by taking into account the convective heat and plasma losses by the transverse flux. Transition from the uniform to contracted state was analyzed. It was shown that such transition experiences a hysteresis, and that the critical current of the transition increases when the pressure (gas density) drops. Possible coexistence of the contracted and uniform state of the plasma in the discharge where the current flows along the density gradient of the background gas was discussed. In this talk the problems related to the dynamic contraction of the current channel inside a quasineutral positive column of a self-sustained glow discharge in molecular gas in a rectangular duct with convection cooling will be discussed. Study presented in this talk was stimulated by the fact that there are large number of experiments on the dynamic contraction of a glow discharge in nitrogen and air flows and a many of possible applications. Similar processes play a role in the powerful gas-discharge lasers. In addition, the problem of dynamic contraction in the large volume of non-equilibrium weakly ionized plasma is closely related to the problem of streamer to leader transitions in lightning and blue jets.

  18. 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)

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

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

  3. Strategic implications of gas to liquids technology for the natural gas industry

    International Nuclear Information System (INIS)

    Russell, B. J.

    1998-01-01

    A new and economical gas to liquids (GTL) technology is described that promises to substantially increase industry's ability to exploit many trillions of cubic feet of largely unmarketable reserves of natural gas. The technology turns the gas into a form that overcomes prohibitive transportation costs, avoids long-term, high-risk, take-or-pay contracts, and helps satisfy the demand for cleaner liquid products. Widespread application of GTL technology is credited with having the power to ease the burden on every segment of the petroleum industry, from exploration through petrochemicals, and into allied industries such as electric power generation. It is claimed that in situations where GTL is the only economic option, it will create an entirely new set of opportunities. Among these are the monetization of known stranded gas and the early development of remote gas discoveries or of oil discoveries associated with gas. It will cause a re-evaluation of exploration strategies by upgrading gas prospects in remote locations and new investment options to countries with shut-in gas or heavy oil or tar sand reserves. The monetization of associated gas when reinjection is no longer needed or desired could occur. Extensive applications offshore and adjacent to coastal reserves and multiple options for refiners facing heavier, higher-sulfur crude slates are possible. The outlook for Syntroleum's version of the GTL process, and the 'grant-back' provisions of Syntroleum's license agreements with companies such as Texaco, ARCO, Marathon, Criterion Catalyst, Catalytica, and ABB, giving each licensee access to the improvements of the other licencees, and the joint development agreements with these companies, were also discussed. 6 refs

  4. Canadian natural gas and climate change

    International Nuclear Information System (INIS)

    2002-03-01

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

  7. The role of Liquefied Natural Gas (LNG) in the European gas market

    International Nuclear Information System (INIS)

    Mahan, A.

    2003-06-01

    The purpose of this paper is to discuss the role that Liquefied Natural Gas (LNG) might play in the future EU gas market. LNG imports are not likely to have a place in the Netherlands soon, but they could make an important contribution to the volume and diversity of Europe's gas supplies. An important characteristic of LNG is its inherently high costs, throughout the whole chain, from the wellhead to the market. These costs are considerably higher than the costs of bringing oil to the market. Cost considerations, in combination with the rigidity of the gas market, have led to the use of long-term contracts as a basis for the business, as is the case for the long haul pipeline gas business. Costs have come down considerably and further cost reductions are 'in the pipeline'. While this does not alter the fundamentals of the business it has nonetheless helped to extend the reach of LNG. LNG from the Middle East to Europe has now become economically feasible. The high gas prices of recent years have further fuelled the expansion of the LNG business. Supported by a rapidly growing global economy at the turn of this century, many prospects are under development. The positive economic outlook has seen more speculative positioning in every segment of the LNG chain, while more vertical integration has been industry's response to market liberalisation. The more recent slowdown of the market economies has created a surplus of LNG, which is finding its way onto the markets through short-term and spot transactions. The short-term business will grow over the next few years as more LNG and shipping capacity comes on-stream. However, given underlying high costs and limited flexibility, it should be expected that new projects, currently under consideration, will only be developed on the basis of long-term contracts, thus returning to a balance between supply and demand. For these same reasons, LNG will not likely develop the same the liquidity as that of the oil market. The global

    Natural gas heats our homes, powers our factories, and increasingly generates electricity, safely and cleanly. Over recent decades, it has been an important element of secure, affordable, and environmentally responsible energy supply. But as production from IEA member countries declines, supplies will have to come from sources in more distant regions. What aspects of OECD gas markets need to be improved to deliver greater security and efficiency? What are the risks of increasing reliance on imports from Russia and the Middle East? Are strategic stocks of natural gas - similar to emergency oil stocks - a viable safety net to a supply disruption? Will there be enough investment in pipeline gas or will more need to be spent on LNG? What are the impacts of gas security on oil markets and power generation security? What do changes in the LNG industry mean for traditional contract terms? This publication, the second issue in a new IEA publications series, addresses key questions in this dynamic market. It offers a global appraisal of current trends in the light of the most recent historical data, including supply and demand projections to 2015.

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

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

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

    Yan, Song; Lang, Liu; Licheng, Ling

    2001-01-01

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

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

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

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

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

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

    International Nuclear Information System (INIS)

    Victor, D.G.

    1990-01-01

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

    2010-01-01

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

    Driving on natural gas (CNG, Compressed Natural Gas) has been the talk of the industry for many years now. Although the benefits of natural gas as an engine fuel have become well-known, this phenomenon does not seem to gain momentum in the Netherlands. Over the last few months, however, the attitude towards CNG seems to be changing. Energy companies are increasingly engaged in commercial activities, e.g. selling natural gas at petrol stations, an increasing number of car manufacturers are delivering natural gas vehicles ex-works, and recently the NGV (Natural Gas Vehicles) Holland platform was set up for the unequivocal marketing of natural gas as an engine fuel

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

    1999-09-27

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

    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

    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)

    Environmental and economic benefits could accrue from a safe, above-ground, natural-gas storage process allowing electric power plants to utilize natural gas for peak load demands; numerous other applications of a gas storage process exist. A laboratory study conducted in 1999 to determine the feasibility of a gas-hydrates storage process looked promising. The subsequent scale-up of the process was designed to preserve important features of the laboratory apparatus: (1) symmetry of hydrate accumulation, (2) favorable surface area to volume ratio, (3) heat exchanger surfaces serving as hydrate adsorption surfaces, (4) refrigeration system to remove heat liberated from bulk hydrate formation, (5) rapid hydrate formation in a non-stirred system, (6) hydrate self-packing, and (7) heat-exchanger/adsorption plates serving dual purposes to add or extract energy for hydrate formation or decomposition. The hydrate formation/storage/decomposition Proof-of-Concept (POC) pressure vessel and supporting equipment were designed, constructed, and tested. This final report details the design of the scaled POC gas-hydrate storage process, some comments on its fabrication and installation, checkout of the equipment, procedures for conducting the experimental tests, and the test results. The design, construction, and installation of the equipment were on budget target, as was the tests that were subsequently conducted. The budget proposed was met. The primary goal of storing 5000-scf of natural gas in the gas hydrates was exceeded in the final test, as 5289-scf of gas storage was achieved in 54.33 hours. After this 54.33-hour period, as pressure in the formation vessel declined, additional gas went into the hydrates until equilibrium pressure/temperature was reached, so that ultimately more than the 5289-scf storage was achieved. The time required to store the 5000-scf (48.1 hours of operating time) was longer than designed. The lower gas hydrate formation rate is attributed to a

    The reform of the EEG in Germany, a positive global development in natural gas, the decline in oil prices, questions about the security of supply in Europe, and not least the effect of the decision by E.on at the end of 2014 have moved the gas industry. Gas has the lowest CO{sub 2} emissions of fossil fuels. Flexibility, storability, useful for networks and the diversity in the application make it an ideal partner for renewable energy. However, these complementary properties are valued at wind and photovoltaics internationally and nationally different. The situation in the gas power plants remains tense. LNG - liquefied natural gas - is on the rise.

  16. The US Natural Gas Exports: New Rules on the European Gas Landscape

    International Nuclear Information System (INIS)

    Cornot-Gandolphe, Sylvie

    2016-06-01

    This study addresses the consequences of US Liquefied Natural Gas (LNG) exports towards Europe, in particular on the strategy of Russia, the EU's main gas supplier. The shale gas revolution has profoundly changed the US gas scene and the competitiveness of gas on the US market. The abundant resources and sharp rise in production have resulted in surplus production and have driven the US gas prices down. The price spread between regional markets (United States, Europe, and Asia) has led US producers to look for new export opportunities. After a lively debate between advocates of exports, mainly gas producers, and their critics, mainly the major industrial users who were worried about a price increase, US LNG exports started in late February 2016 with the first cargo from the Sabine Pass (Cheniere) liquefaction plant exported to Brazil. Four other liquefaction plants are currently under construction. In 2020, the United States could become the third largest exporter in the world after Australia and Qatar. The US LNG exports will revolutionise international trade in LNG. Their contract structure (linked to the US gas spot price, no destination clauses, and tolling agreements) and the projected volumes will enable greater flexibility in the international LNG market and facilitate price convergence between regional markets. However, the US exports are starting in a market very different from that envisioned at the start of the 2010's when the export projects were launched. The drop in oil prices, the entry into production of new liquefaction capacities since 2014, and the slowdown in demand growth in Asia have driven LNG prices down on import markets. After four years of tight supply, the market is now in a surplus situation which should continue until the turn of the decade. These new conditions are profoundly changing the economics of US LNG export projects, which is questioned in the short term: the current prices are insufficient to cover the full cost of the

    1994-01-01

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

    The study, 'Assesment of greenhouse gas emission from natural gas' by independent consultants Energetics Pty Ltd, shows that natural gas has significantly fewer greenhouses gas emissions than either black or brown cola for the defined life cycle stages. The life cycle emissions from natural gas use by an Australian Major User are approximately 50% less than the emissions from Victorian brown coal and approximately 38% less than the emissions from Australian average black coal. Australian Best Practice gas fired electricity generation is estimated to emit between 514 and 658 kg CO 2 e/MWh. By comparison, Australian Best Practice coal-fired electricity generation is estimated to emit between 907 and 1,246 kg CO 2 e/MWh for black and brown coal respectively. Greenhouse gas emissions from Australian Best Practice gas-fired electricity generation using combined cycle gas turbines (including full fuel cycle emissions) vary from 41% to 46% of the emissions from brown coal-fired electricity generation and 57% to 64% of emissions from black coal-fired electricity generation. Greenhouse gas emissions from direct gas supply water heating range from 1,470 to 2,042 kilograms per annum. This compares with emissions of 1,922 to 2,499 kg for electric heating from gas-fired electricity generation and 3,975 to 5,393 kg for coal-fired electricity generation. The implications for greenhouse policy nationally are also discussed, emphasising the need to review national energy policy, currently tied to 'fuel neutrality' doctrine

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

    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.

    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

    The role of various atmospheric pollutants in environmental changes and the global water cycle, carbon cycle, and energy balance is explained. The role of sulfur dioxide and nitrogen oxides in acid deposition is also outlined. The pollutants that contribute to environmental problems include nitrogen oxides and volatile organic compounds, carbon dioxide, and other greenhouse gases. The potential for natural gas utilization to mitigate some of these pollution problems is explored. Natural gas combustion emits less carbon dioxide and nitrogen oxides than combustion of other fossil fuel, and also does not produce sulfur dioxide, particulates, or volatile organics. Other pollution controlling opportunities offered by natural gas include the use of low-polluting burners, natural gas vehicles, and cogeneration systems. 18 figs., 4 tabs

    Azerbaijan, a landlocked post-Soviet country since its independence has been trying to utilize its energy resources in its foreign policy. With production-sharing agreements with Western oil companies beginning with the 1994 signing of the "Contract of the Century" and the construction of the Baku-Tbilisi-Ceyhan oil pipeline Azerbaijan successfully opened up its energy sector for foreign investment and used pipelines to stabilize its economy and underpin its foreign policy. The discovery of the Shah Deniz gas field opened up new opportunities for Baku to buttress its foreign policy goals with the export of natural gas. In this Master's thesis I will evaluate and show the importance and significance of natural gas export in Azerbaijani foreign policy.

    2001-01-01

    Despite completing 8,900 gas wells in year 2000, the deliverability of natural gas out of the Western Canadian Sedimentary Basin (WCSB) was stagnant which has left many analysts wondering whether the basin has reached its limit. It also leaves many wondering if gas producers will be able to meet the strong demand for natural gas in the future. Nearly all new electrical generation being built in the U.S. is gas-based due to strict new environmental standards limiting the growth in hydro and coal-powered generation. Any future coal plants will use gasification technology and combined cycle turbines. Combined cycle turbines developed by Boeing and Lockheed are more efficient than combustion turbines, making gas more competitive with fuel alternatives. The lack of growth in natural gas supply has left storage levels near record lows. Demand is expected to increase in 2001 by 3.2 per cent to 23 trillion cubic feet in the U.S. Longer term, major new reserves must be brought on stream to meet this demand. It was noted that the easy discoveries within the WCSB have been made. The new plays are smaller, more technically complex and expensive which suggests that more investment is needed in training geologists, geophysicists and petroleum engineers to find new reserves. The Canadian Energy Research Institute agrees that there is enough gas in Alberta and British Columbia to meet current demands but efforts must shift towards drilling in the foothills front and northwest regions of Alberta to increase deliverability. Brief notes on several gas finds by various oil and gas companies in the area were presented. The article also discussed the huge untapped potential of northern reserves. Analysts have noted 44 Tcf of proven reserve, with a potential of 165 Tcf. In addition, new pipelines from the Alaskan North Slope and the Mackenzie Delta could transport nearly 2 Tcf annually to market. Wells drilled by Chevron and Paramount at Fort Liard in 1999 initially flowed at rates up to

    2001-12-01

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

  10. OIL AND GAS FUTURES AND OPTIONS MARKET

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Energy mineral resources markets are represented by complex supply and demand ratios which are depending on different factors such as technical (transport and geopolitical. The main specific of energy markets is represented by an uneven geographic distribution of hydrocarbon reserves and exploration on one hand and energy consumption on the other. World oil markets, although geographically localized, because of specific market trade, represent unique global market with decreasing price difference. Price differences are result of development of a transport possibilities of oil supply. Development of transport routes of natural gas and increasing number of liquefied natural gas terminals in the world give pressure to natural gas market and its integration into global gas market. Integration of regional gas markets into a common European gas market is main energy policy of EU concerning natural gas. On the other hand, there are still significant price differences on some markets (e.g. United States of America - South East Asia. Development of global energy markets is enabled by development of a futures and options contracts of an energy trade which have replaced bilateral contract deals between producers and consumers. Futures contracts are standardized contracts traded on exchanges. Buyer agrees to buy certain quantity of stock for an agreed upon price and with some future delivery date. Option is a contract which gives a buyer the option of the right to buy (or sell, depending on the option an asset at predetermined price and at a later date. Stocks price risk can be managed with the purchase and selling futures and options contracts. This paper deals with futures and options energy markets and their market strategies.

  11. Accounting for fuel price risk when comparing renewable togas-fired generation: the role of forward natural gas prices

    Energy Technology Data Exchange (ETDEWEB)

    Bolinger, Mark; Wiser, Ryan; Golove, William

    2004-07-17

    Unlike natural gas-fired generation, renewable generation (e.g., from wind, solar, and geothermal power) is largely immune to fuel price risk. If ratepayers are rational and value long-term price stability, then--contrary to common practice--any comparison of the levelized cost of renewable to gas-fired generation should be based on a hedged gas price input, rather than an uncertain gas price forecast. This paper compares natural gas prices that can be locked in through futures, swaps, and physical supply contracts to contemporaneous long-term forecasts of spot gas prices. We find that from 2000-2003, forward gas prices for terms of 2-10 years have been considerably higher than most contemporaneous long-term gas price forecasts. This difference is striking, and implies that comparisons between renewable and gas-fired generation based on these forecasts over this period have arguably yielded results that are biased in favor of gas-fired generation.

  12. Supply prospects and network integration in the European natural gas sector

    International Nuclear Information System (INIS)

    Bergmann, B.

    1998-01-01

    At least for the next 10-15 years, natural gas will be the fastest growing energy form in Europe, with a higher rate of growth in consumption (from a lower base) in central Europe than in western Europe. Although most of the prospective demand until 2010 is covered by signed import contracts and indigenous production, important additional gas supply capacity still has to be developed out of a plenitude of reserves within and (in the long run primarily) outside western and central Europe. The real problem is how to mobilise the reserves economically and direct them towards the European market, in competition with other markets. Europe has a sophisticated transmission system whose development has gone hand-in-hand with long-term import agreements. Among the missing links is the Interconnector, which, at the end of 1998, is due to integrate the UK and Ireland into mainland Europe. This is expected to enhance security of supply in both areas, to balance prices and maybe also to foster ideas of liberalisation. Overall, the European gas industry is in an excellent position to develop the supply of gas in an environmentally benign way. The future belongs all the more to natural gas, the fewer the mistakes that are made when it comes to matters of legal frameworks and taxation

  13. Convergence to the long-run equilibrium: the case of natural gas markets

    Lien, D.; Root, T.H.

    1999-01-01

    Intuitively, the persistence of a shock may last longer in futures contracts with a longer maturity. Estimation of the speed with which different contract lengths converges to the long-run equilibrium following a shock, provides a means for comparing the informational efficiency of the contracts. Standard empirical investigation of the response of a market to a shock utilizes impulse response analysis. However, this analysis is problematic since there is not a unique variance-covariance decomposition. Pesaran and Shin [Pesaran, M.H., Shin, Y., 1996. Cointegration and speed of convergence to equilibrium. J. Econ. 71, 117-143] introduced an alternative to the standard impulse response analysis, the persistence profile. By estimating the one step ahead forecast error for the entire system, the persistence profile provides a unique measure of the effect of the shock. This paper empirically estimates persistence profiles for the natural gas futures market. The findings indicate that the persistence of a shock does increase with the contract length.

  19. How is Order 636 affecting the gas producing industry?

    International Nuclear Information System (INIS)

    1993-01-01

    This paper is an interview with an energy representative for a major gas-producing company regarding the impact of the Federal Energy Regulatory Commission (FERC) Order 636. This legislation was suppose to streamline the interstate transportation of natural gas unhindered by local distribution company (LCD) interference. Many times these LCD's owned a portion of the necessary pipeline route used to transport natural gas, and as a result, had a priority on purchasing pipeline gas whenever they needed. This could, in turn, result in a depletion of contract gas which was in-route to a specified contract market. Such interferences caused problems with the contract markets, but could boost the net profits to natural gas companies who had excess gas that could be sold in-route to other markets. This paper addresses both the pro's and cons' of this new regulation on both the pipeline and gas producing companies

    1998-01-01

    Risk analysis and techniques to manage risk as it pertains to the natural gas industry were discussed. Portfolio allocations for long-term, short-term fixed price and variable price contracts were described. Options were defined as a market instrument offering the benefits of a fixed price purchase or sale without the obligation of incurring financial or opportunity losses if the market goes against the option buyer. Options should be used as a defence strategy to protect portfolios from price risk in times of uncertainty and to take advantage of current floating market conditions without making a full price commitment. Options can also be used as an offensive strategy to make a directional play on the market or on volatility. Options selling was regarded as a much higher risk than options buying. The variables that affect options premiums were: (1) volatility, (2) time to expiration, (3) underlying price versus strike price, and (4) flexibility. Williams Energy's new world class energy trading floor in Tulsa, Oklahoma was also described. Williams is the largest-volume transporter of natural gas in the U.S. with more than 27,000 miles of pipelines. Williams pipelines transport 16 per cent of all the natural gas used in the U.S. and the company is one of the nation's largest natural gas gatherers and processors. tabs., figs

  1. Experimental Study of Gas Explosions in Hydrogen Sulfide-Natural Gas-Air Mixtures

    Full Text Available An experimental study of turbulent combustion of hydrogen sulfide (H2S and natural gas was performed to provide reference data for verification of CFD codes and direct comparison. Hydrogen sulfide is present in most crude oil sources, and the explosion behaviour of pure H2S and mixtures with natural gas is important to address. The explosion behaviour was studied in a four-meter-long square pipe. The first two meters of the pipe had obstacles while the rest was smooth. Pressure transducers were used to measure the combustion in the pipe. The pure H2S gave slightly lower explosion pressure than pure natural gas for lean-to-stoichiometric mixtures. The rich H2S gave higher pressure than natural gas. Mixtures of H2S and natural gas were also studied and pressure spikes were observed when 5% and 10% H2S were added to natural gas and also when 5% and 10% natural gas were added to H2S. The addition of 5% H2S to natural gas resulted in higher pressure than pure H2S and pure natural gas. The 5% mixture gave much faster combustion than pure natural gas under fuel rich conditions.

    Sunoco Inc. is a subsidiary of Suncor Energy, one of Canada's largest integrated energy companies having total assets of $2.8 billion. As one of the major energy suppliers in the country, Sunoco Inc has a substantial stake in the emerging trends in the natural gas industry, including the Canadian natural gas price debate. Traditionally, natural gas prices have been determined by the number of pipeline expansions, weather, energy supply and demand, and storage levels. In addition to all these traditional factors which still apply today, the present day natural gas industry also has to deal with deregulation, open competition and the global energy situation, all of which also have an impact on prices. How to face up to these challenges is the subject of this discourse. tabs., figs

    Two state companies are in charge of natural gas supply in Kazakhstan. They buy, transport and sell natural gas and have monopolized the industry and provoked increase of gas prices. Ministry of Oil and gas Industry proposed demonopolization. The restructuring that took place caused new distribution of tasks in the gas industry. A more competitive environment was created leading to normalization of the natural gas prices. All economic subjects were granted the right to acquire gas regardless the type of ownership. Measures implemented for reorganization of gas companies contributed to the reduction of gas transport costs and prices by 50% and to decrease of gas prices in the southern regions by 50%. Despite these measures gas prices for household sector are still unchanged and are below the import prices, the main reason being the low average household income

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

    Geologically estimated natural gas resources are 500 Tcm. With the advance in geological science increase of estimated resources is expected. Natural gas reserves in 2000 have been proved to be around 165 Tcm. As it is known the reserves are subject to two constraints, namely: capital invested in the exploration and drilling technologies used to discover new reserves. The natural gas scarcity factor, i.e. ratio between available reserves and natural gas consumption, is around 300 years for the last 50 years. The new discovery of natural gas reserves has given rise to a new energy strategy based on natural gas. Natural gas utilization is constantly increasing in the last 50 years. With new technologies for deep drilling, we have come to know that there are enormous gas resources available at relatively low price. These new discoveries together with high demand for the environment saving have introduced a new energy strategy on the world scale. This paper presents an evaluation of the potential natural gas utilization in energy sector. As the criteria in this analysis resource, economic, environmental, social and technological indicators are used. Among the potential options of gas utilization following systems are considered: Gas turbine power plant, combine cycle plant, CHP power plant, steam turbine gas-fired power plant, fuel cells power plant. Multi-criteria method was used for the assessment of potential options with priority given to the Resource, Economic and Social Indicators. Results obtained are presented in graphical form representing priority list of potential options under specific constraints in the priority of natural gas utilization strategy in energy sector

    The paper discusses the natural gas market and environmental needs with topics as follow: Importance of the North Sea region; sustainable development on the balance between economic use and environmental protection; role of natural gas in meeting energy demand: market needs, technologies, environmental aspects. According to the author, natural gas causes minimal pollutants because it contains virtually no pollutant-forming substances such as heavy metals, sulphur, chlorine or fluorine. No solid residues exist in the combustion space such as ash, slag, dust or soot, and the formation of thermal NO x through natural gas combustion has decreased to a very large extent as a result of technical advances. Natural gas can make a significant contribution towards reducing CO 2 emissions due to its very high hydrogen content. 12 figs

    The expansion of the gas industry in our country in the actual days, allied to the constitutional authorization for the private initiative acting in this sector provides the establishment of precise rules to the consequent market consolidation. In spite of the exigencies, one realises that the law no. 9.487/97, often denominated as Oil Law, does not rule in its fullness the specifics situations concerned to the natural gas. Despite the elaboration of the natural gas Law is a target of the governmental politics, overcoming the question pondered, there is not, until now, a detailed study of the legislative competency regimen relative to the natural gas. This very work, notably, gathers relevance in front of the State shape adopted in our country and the federative pact historically built; while aiming the complex distribution of legislative power made to each one of the political entities, there is need to establish the limits of performance to the sort of the coming gas Law, under penalty its arising with an unconstitutionality defect confronting to the federative pact. In the sense of clarifying the probably doubts around the subject and allowing that power comes closer to the people are our considerations proposed for. (author)

    The development of the gas field off Sable Island and the imminent construction of a gas pipeline which will deliver natural gas to New Brunswick has prompted a thorough examination of energy-related issues in the province. This report presents the findings of the provincial energy committee which examined the implications of the arrival of natural gas to the province. The committee held a series of public hearings and consultations, and also received written submissions. After a historical perspective on natural gas as an energy source in the province and a review of the gas industry participants and their interests, the report discusses such issues as gas pipeline economics, local distribution company operations, infrastructure development, the regulatory framework, energy market competition, regional price equity, development of in-province gas sources, pipeline access, pipeline laterals and expansions, establishment of gas distribution franchises, municipal involvement in gas development, the impact of gas industry development on electric utility restructuring, and the environmental benefits of natural gas. Finally, recommendations are made regarding how natural gas should be regulated and distributed

    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 has the potential to increase the biofuel production output by combining gas- and biomass-to-liquids (GBTL) processes followed by naphtha and diesel fuel synthesis via Fischer-Tropsch (FT). This study reflects on the use of commercial-ready configurations of GBTL technologies and the environmental impact of enhancing biofuels with natural gas. The autothermal and steam-methane reforming processes for natural gas conversion and the gasification of biomass for FT fuel synthesis are modeled to estimate system well-to-wheel emissions and compare them to limits established by U.S. renewable fuel mandates. We show that natural gas can enhance FT biofuel production by reducing the need for water-gas shift (WGS) of biomass-derived syngas to achieve appropriate H2/CO ratios. Specifically, fuel yields are increased from less than 60 gallons per ton to over 100 gallons per ton with increasing natural gas input. However, GBTL facilities would need to limit natural gas use to less than 19.1% on a LHV energy basis (7.83 wt %) to avoid exceeding the emissions limits established by the Renewable Fuels Standard (RFS2) for clean, advanced biofuels. This effectively constitutes a blending limit that constrains the use of natural gas for enhancing the biomass-to-liquids (BTL) process.

  14. Competition in trade with natural gas

    International Nuclear Information System (INIS)

    1999-01-01

    On 22 June 1998, the European Parliament and the Council of Europe adopted Directive 98/30/EC on common rules for the internal market for natural gas. The Natural Gas Market Directive is aimed at increasing the competition on the gas market and creating an internal market for natural gas. To achieve this, the Directive includes provisions for ensuring that owners of transmission and distribution networks will allow other players access to these networks. The Directive is much more far-reaching and comprehensive than the present Swedish legislation in the field of natural gas. The main task of the committee is to submit a proposal for natural gas legislation that will meet the requirements of the new Directive. According to the committee directives, the work on the new legislation should aim at the regulations serving as a basis for a socio economically efficient market. However, it should also be borne in mind that the Swedish natural gas market is less developed than the markets in most other European countries, and that a lack of equilibrium in the opening of the gas markets should be avoided. Current international deliberations concerning the natural gas network in the Nordic countries and the Baltic Sea region should also be taken into account. Chapter 1 gives more detailed particulars of the points of departure for the work of the committee and the implementation of the work. The report is arranged in the form three main parts, i.e. a background part, a part describing the points of departure, and a proposals part

Its presence depends on the origin, as well as the own process used in the gas treatment, it can bring problems to the pipes and the final applications of natural gas (NG). The National Petroleum Agency (ANP) in its entrance number 104/02, establishes that the quantity of H{sub 2}S in NG, of national or imported origin, commercialized at the country can only be at the most 10 - 15 mg/m{sup 3}. In the Natural Gas Processing Unit (UPGN) different methods are used for the removal of H{sub 2}S, the absorption process (e.g. with aminas, Sulfinol{sup R} process) or for adsorption in tower filled with activated coal, zeolites and Sulfatreat{sup R}. In this work, the adsorbent material used is the mineral clay Paligorsquita.

    This paper uses evidence on policies, markets and private transactions to discuss the experience of natural gas infrastructure integration in the Southern Cone of Latin America. The argument is that contracts on international exchanges supported by infrastructure may become incomplete due to contingencies related to policy-induced price distortions not anticipated at the moment of writing. Beyond regulatory risk mitigation, it calls for back-up contract provisions designed to cope with aggregate imbalances and for some supranational coordination related to information about market conditions and on energy planning dialogues that test consistency and stress situations in markets where exports originate.

    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.

These include lower capital costs, positive environmental impacts, the use of proven technology, and an adequate resource base with a highly reliable and flexible transportation system. However, it is also clear that FERC's regulation of pipeline rates and operating practices has a direct impact on the bottom line of electric generators. a sober understanding of these rules, a careful integration of the rules into project documents, and a more commercial approach to transportation contracts will enhance the revenues and control the risks of the financially successful gas-fired electric generators

  6. Natural gas purchasing for cogeneration projects

    Kubacki, J. Jr.

    1992-01-01

    This paper reports on the primary cost component for most gas-fired cogeneration or on-site power projects, cost of natural gas. Often gas comprises 50 to 65% of total project costs over the life of the project. Thus it is very important to focus on natural gas sourcing, pricing, transportation and storage. This important task should not be blindly delegated to a gas supplier. The end user must develop a gas strategy that results in the most cost-effective burnertip price. Long-term natural gas supplies are usually source from the three major producing regions: Mod-Continent, Gulf Coast, and Western Canada. A well-reasoned gas strategy must include: determination of transportation and distribution options from the project site to potential gas sources (including direct interconnection of the project to interstate pipelines); acquisition of competitive gas bids from suppliers in appropriate regions; negotiation of potential discounts from interstate pipelines and local distribution companies (LDCs); fine-tuning project economics by, for example, using storage to maximize transportation load factor; and pricing mechanisms that meet economic parameters of the project. This paper uses a hypothetical project in the Midwest to examine the major factors in devising a cost-effective natural gas sourcing

    Natural gas has been proposed as a transition fuel. The combustion of natural gas emits less CO 2 per unit of energy than the combustion of other fossil fuels. Increased reliance upon natural gas in preference to other fossil fuels would be encouraged to mitigate greenhouse gas releases while more comprehensive responses are devised to provide more time for adaptation to the inevitable climate change. In this context, the article overviews of natural gas and its relation with the environment

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

    International Nuclear Information System (INIS)

    1995-12-01

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

    Ophir Corporation was awarded a contract by the U. S. Department of Energy, National Energy Technology Laboratory under the Project Title ''Airborne, Optical Remote Sensing of Methane and Ethane for Natural Gas Pipeline Leak Detection'' on October 14, 2002. The scope of the work involved designing and developing an airborne, optical remote sensor capable of sensing methane and, if possible, ethane for the detection of natural gas pipeline leaks. Flight testing using a custom dual wavelength, high power fiber amplifier was initiated in February 2005. Ophir successfully demonstrated the airborne system, showing that it was capable of discerning small amounts of methane from a simulated pipeline leak. Leak rates as low as 150 standard cubic feet per hour (scf/h) were detected by the airborne sensor.

    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)

    2011-01-01

    In 2009 and 2010, major offshore natural gas reserves were discovered near the State of Israel. This article examines Israel's newly discovered natural gas reserves and the implications of this discovery for Israel, the Middle East, and the Mediterranean region. The article will discuss Israel's energy security approach; the role of natural gas in Israel's energy consumption patterns; the organization of Israel's natural gas sector; regional political and security implications of the natural gas discoveries; the prospects for export, and the outlook for various natural gas markets. These new discoveries significantly improve Israel's energy security. They may also spur Israel to develop technologies related to utilization of natural gas in a variety of sectors, such as transportation. The discoveries may contribute to the emergence of a number of maritime border delimitation conflicts in the Eastern Mediterranean. At current volumes, the Israeli discoveries will not be a game-changer for gas markets in southern Europe or liquefied natural gas (LNG) markets. However, they will lead to expanded natural gas consumption in the region. In addition, offshore exploration efforts in Israel and in neighboring countries are intensifying. Additional discoveries may turn the Eastern Mediterranean region into a new source of natural gas and oil. - Highlights: → In 2009 and 2010, major natural gas deposits were discovered offshore of Israel's port city of Haifa. → They will satisfy a large portion of Israel's domestic energy consumption needs for a number of decades. → The gas discoveries have created an opportunity to fundamentally change the country's energy policies. → Additional discoveries may turn the Eastern Mediterranean region into a new source of natural gas and oil. → Israel could become a supplier of natural gas to neighbors in the Middle East region, such as Jordan.

    Options for the liberalization of the Dutch natural gas market have been investigated. Three models are compared and assessed for the impacts on the economic performance, the national interests and the so-called public tasks. The results of the report can be used to base the proposals for a new Natural Gas Act, which is expected to be sent to the Dutch parliament in the spring of 1999. The three liberalization models are specified according to the different phases in the industrial column of natural gas. Except for transport (limited possibilities) and distribution (monopolistic character and thus not suitable for market development), market development is possible in all the phases of the column. The models are the cooperation model (equal position for the natural gas trade company Gasunie and the natural gas distribution companies, and management of the natural gas infrastructure and the Dutch gas reserves by means of mutual tuning, cooperation and coordination), the EZ-model (price mechanism for the tariffs for natural gas, and access to the natural gas network through negotiated third party access (TPA) with indicative prices and conditions), and the market model (optimal use of market development options to stimulate the economic performance, introduction of price mechanism options, access through regulated TPA with tariffs, based on long-term marginal costs, role of the government limited to a favorable policy with respect to access to the network, competition and security of the interests which arise from the exploitation of the Dutch natural gas fields). 26 refs

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

  2. The price of natural gas

    Natural gas used to be a relatively cheap primary energy source, always at a discount to crude oil (on a comparative British thermal unit basis). It gradually evolved into a major resource during the 20th century - reaching a 24 per cent share of global primary energy in 1999. In the year 2000, natural gas prices in the USA rose to unheard-of highs of 10/million US dollars Btu, ushering in a new era, with natural gas at a 120 per cent premium to crude oil. This clearly was a watershed for gas, somehow similar to the 1973-74 watershed for oil prices. And similarly, any return to the status quo-ante looks rather improbable, although a number of experts (alongside the International Energy Agency) still believe the 2000 price 'spike' to have been ''only transitory''. The consequences of higher gas prices (at a level equal to crude oil prices on a Btu basis) will be multifaceted and momentous, altering habits and uses in downstream industries and economic sectors, as well as providing added income for major gas-exporters, such as Russia, Canada and Algeria. Another potential consequence of the 2000 watershed might be to propel US standard prices (such as the 'Henry Hub' spot) to international status and gas price-setter, as the 'WTI spot' became an 'international benchmark' for crude oils in the post-1993 era. For the time being, the equality of gas and oil prices has become the new norm; but, in the longer term, a discount of crude oil relative to natural gas might be envisaged, as the latter is a cleaner fuel and emits less carbon dioxide when used.

    The treatise describes potential market forces which could evoke changes in the structure of the European gas industry or in its types of contract. It shows that a price differentiation at the borehole may lead to an increase in natural gas deliveries for the European markets. A study of the development of the North American gas industry over the last few decades supports this expectation. The treatise ends with the statement that an application of the North American experiences to the European gas industry is unlikely, but it does not rule out the possibility of market forces or the EEC Commission creating a basis for similar structural reforms in the European gas industry.

    The state of Quebec's energy industry was discussed at this conference. Quebec's energy market is distinct by the diversity of its clients, the resource exploitation sector and its types of industries. As such, the energy needs are specific and the strategies for developing natural gas should be adapted to meet these needs. This conference focused on recent energy policy developments at Quebec's Office of Energy and other regulatory bodies. Topics of discussion included the risks and opportunities of the natural gas export market; volatile gas prices; public consultation processes; perspectives of large energy consumers; hydrocarbon potential and exploration in Quebec; natural gas exploration and development in Quebec; energy security and strategies to address carbon dioxide emissions. Other topics of discussion included the investment climate in Quebec; the profitability of Canada's oil and gas sector and refining capacity in Quebec. The conference featured 17 presentations, of which 6 have been indexed separately for inclusion in this database. refs., tabs., figs

    The problem of saturation in the natural gas distribution pipelines in Brazil is not urgent, but it's possible to notice the need of reinforcements in some extensions. Price regulation does not consider this problem yet, but it's already predicted the adoption of a three-part tariff considering a contracted capacity for some industrial consumers - industries that buy more than 500.000 m3/month in the COMGAS distribution area. Some industries, like potteries and glass makers, would probably not suffer strong impacts with the implementation of this three-part tariff, since the majority of their manufacturing processes are continuous. Others sectors would probably have negative impacts with the contracted capacity, like pulp and paper, metallurgy and textile industries. The way that industry will manage the contracted capacity is still unknown. Some possibilities are: considering natural gas as one of the variables in the productions' decision; having a 'Back-up' system when the consumption surpass the contracted capacity; switch fuels when total consumption is above 500.000 m{sup 3}/month, so that the company does not fit in the three-part tariff. The three-part tariff has not been published yet, but it's already necessary a sign to the market that this will occur in the near future, so that the companies involved can already create a strategy for the use of natural gas. This signal is already predicted in the Technical Paper number X of CSPE. (author)

  7. IGNITION IMPROVEMENT OF LEAN NATURAL GAS MIXTURES

    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.

    Advocates of energy efficiency and renewable energy have long argued that such technologies can mitigate fuel price risk within a resource portfolio. Such arguments--made with renewed vigor in the wake of unprecedented natural gas price volatility during the winter of 2000/2001--have mostly been qualitative in nature, however, with few attempts to actually quantify the price stability benefit that these sources provide. In evaluating this benefit, it is important to recognize that alternative price hedging instruments are available--in particular, gas-based financial derivatives (futures and swaps) and physical, fixed-price gas contracts. Whether energy efficiency and renewable energy can provide price stability at lower cost than these alternative means is therefore a key question for resource acquisition planners. In this paper we evaluate the cost of hedging gas price risk through financial hedging instruments. To do this, we compare the price of a 10-year natural gas swap (i.e., what it costs to lock in prices over the next 10 years) to a 10-year natural gas price forecast (i.e., what the market is expecting spot natural gas prices to be over the next 10 years). We find that over the past two years natural gas users have had to pay a premium as high as $0.76/mmBtu (0.53/242/kWh at an aggressive 7,000 Btu/kWh heat rate) over expected spot prices to lock in natural gas prices for the next 10 years. This incremental cost to hedge gas price risk exposure is potentially large enough - particularly if incorporated by policymakers and regulators into decision-making practices - to tip the scales away from new investments in variable-price, natural gas-fired generation and in favor of fixed-price investments in energy efficiency and renewable energy.

    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.

    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

    Natural gas, with its environmental advantages, will increase its development in the residential, professional and transportation markets. It will ensure the transition during the progressive implementation of more sustainable energy sources. This paper discusses some possible impacts of the deregulation on the future gas market (investments, risk management, competition, contracts). It is followed by a round table about the expectations of some gas producers (Qatar, Sweden) in front of the development of the European gas market (LNG projects, financing, contracts). (J.S.)

    This presentation outlined natural gas purchasing strategies with particular reference to direct purchase agreements for multi-site, multi-tenant commercial properties. It included an overview of the commercial buyer, the importance of a direct purchase agreement, dealing with an agent, and the procurement process. Direct purchase gas agreements are used for multi-tenant dwellings where tenants pay a proportionate share of costs to heat the building with natural gas. These types of agreements optimize operating costs and offer price stability, thereby contributing to the marketability of the building. The issues that should be considered during the procurement process include: different risk profiles; terms of the contract; current market conditions; futures market; sale of property; acquisition of new properties; and, terms of property management

    The natural gas is natural origin energy (fossil fuel); it contains predominantly 90 percent methane; does not require transformation process for its use; is supplied the 24 hours to commerce, industries and homes by underground pipes; it is lighter than air; it is not corrosive, nor absorbent or toxic. For those reasons a study was performed where it is widely justified why the natural gas ought to be used in vehicles. [Spanish] El gas natural es un energetico de origen natural (combustible fosil), contiene predominantemente 90 por ciento de metano, no requiere proceso de transformacion para su utilizacion, llega directamente las 24 horas del dia a los hogares, comercios e industrias por tuberias subterraneas, es mas ligero que el aire, no es corrosivo, no es absorbente y no es toxico. Por esas razones se hizo un estudio donde se justifica ampliamente porque el gas natural debe utilizarse en vehiculos.

  16. The necessity for storage of natural gas in the Netherlands: In particular the natural gas storage near Langelo, Drenthe, Netherlands

    1994-11-01

    The natural gas supply in the Netherlands will experience a capacity problem once the pressure of the natural gas field Slochteren in the province Groningen will decrease below a certain level. It is expected that this will already happen in the winter of 1996. Underground storage of natural gas reserves is considered to be the only appropriate solution to accommodate this problem. Four environmental organizations in the Netherlands ordered GASTEC, the Dutch research center for natural gas technology, to study the alternatives for natural gas storage in the Netherlands. 7 figs

    The Petroleum Law states that the concession contract will also have provisions regarding the government takes established by the bid tender. However, the criteria for calculating the value of Royalties are set forth in the Decree 2.705/98, enacted to set such criteria, taking into account the volumes of production and the reference prices for oil and natural gas. The following aspects are analyzed in this paper: the method for calculating the volumes subject to the impact of Royalties; definition of the reference price for natural gas, the general rule for setting up the reference price in case the sale was made at market price; the special rule in case the sale was not made on a market basis, in case there is no sale or in case of breach of the conditions set in that Decree; and the settlement of the reference price in situations where only part of the volumes produced are sold on contracts that meet the requirements of the Decree. In conclusion the problems caused by gaps in legislation will be highlighted, particularly with regard to concessions granted to consortia as well as the inconsistencies between the applicable legislation, which may provide different analysis, including by the ANP, according to the features of each case.

    Ruppel, Carolyn D.

    2018-01-17

    Gas hydrate is a naturally occurring, ice-like substance that forms when water and gas combine under high pressure and at moderate temperatures. Methane is the most common gas present in gas hydrate, although other gases may also be included in hydrate structures, particularly in areas close to conventional oil and gas reservoirs. Gas hydrate is widespread in ocean-bottom sediments at water depths greater than 300–500 meters (m; 984–1,640 feet [ft]) and is also present in areas with permanently frozen ground (permafrost). Several countries are evaluating gas hydrate as a possible energy resource in deepwater or permafrost settings. Gas hydrate is also under investigation to determine how environmental change may affect these deposits.

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

    The seminar was designed to focus on the business aspects of developing Asian natural gas resources by inclusion of papers on natural gas markets, the role of banks, and financial case histories of existing projects, and papers on commercial and industrial natural gas utilization. The utilization of natural gas was addressed by papers that targeted small-scale, industrial and utility usage of natural gas in electric power production, and by papers on air conditioning and other applications. Each of these topics is important to the development of the Asian natural gas industry. Together, they formed a balanced program when combined with the opening keynote addresses from Tokyo Gas Company, Ltd., and PETRONAS and a panel discussion on gas pricing. All papers have been processed separately for inclusion on the data base

    This paper illustrates a key lesson related to most uses of long-range climate forecast information, namely that effective weather-related decision-making requires understanding and integration of weather information with other, often complex factors. Northern Illinois University's heating plant manager and staff meteorologist, along with a group of meteorology students, worked together to assess different types of available information that could be used in an autumn natural gas purchasing decision. Weather information assessed included the impact of ENSO events on winters in northern Illinois and the Climate Prediction Center's (CPC) long-range climate outlooks. Non-weather factors, such as the cost and available supplies of natural gas prior to the heating season, contribute to the complexity of the natural gas purchase decision. A decision tree was developed and it incorporated three parts: (a) natural gas supply levels, (b) the CPC long-lead climate outlooks for the region, and (c) an ENSO model developed for DeKalb. The results were used to decide in autumn whether to lock in a price or ride the market each winter. The decision tree was tested for the period 1995-99, and returned a cost-effective decision in three of the four winters.

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

  4. Outlook for Noth American natural gas supplies

    1995-01-01

    The underlying resource base for North America natural gas is large, sufficient for nearly 100 years of current consumption. As such, the issues are not the size of the resource, but how to convert this resource into economically competitive supply. The key questions are: Will the cost (price) of natural gas remain competitive? What is the status of near-term deliverability? Will there be enough supply to meet growing demand? These economic and market issues frame the outlook for gas supplies in North America. Most importantly, they will determine how natural gas emerges from its competition for markets with other fuels and electricity. The paper addresses these questions by examining: (1) the underlying nature of the natural gas resource base; (2) the current status and trends in deliverability; and, (3) the potential of new technologies for producing gas more cost-effectively.

    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

  11. Trading in LNG and natural gas

    International Nuclear Information System (INIS)

    1992-01-01

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

    The life cycle report prepared recently by Energetics for the AGA, Assessment of Greenhouse Gas Emissions from Natural Gas, demonstrates clearly the greenhouse advantage natural gas has over coal in generating electricity. This study also goes one step further in applying this life cycle approach to the use of space and water heating within the home. The study shows the significant green-house advantage that natural gas appliances have over electric appliances. Findings from other studies also support this claim. The natural gas suppliers are encouraged to take advantage of the marketing opportunity that these studies provide, offering the householders the fuel that will significantly reduce their contribution to greenhouse emission

    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)

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

  19. The Pricing of natural gas

    Nese, Gjermund

    2004-11-01

    The report focuses on the pricing of natural gas. The motivation has been the wish of the Norwegian authorities to increase the use of natural gas and that this should follow market conditions. The pricing of gas occurs at present in various ways in the different markets. The report identifies to main factors behind the pricing. 1) The type of market i.e. how far the liberalization of the gas markets has gone in the various countries. 2) The development within the regulation, climate and tax policies. The gas markets are undergoing as the energy markets in general, a liberalization process where the traditional monopoly based market structures are replaced by markets based on competition. There are great differences in the liberalization development of the various countries, which is reflected in the various pricing principles applied for the trade of gas in the countries. The analysis shows that the net-back-pricing is predominant in some countries i.e. that the price is in various ways indexed towards and follow the development of the price of alternative energy carriers so that the gas may be able to compete. The development towards trade places for gas where the pricing is based on offer and demand is already underway. As the liberalization of the European gas markets progresses it is expected that the gas price will be determined increasingly at spot markets instead of through bilateral agreements between monopolistic corporations. The development within the regulation, climate and tax policies and to what extent this may influence the gas prices in the future, are also studied. There seem to be effects that may pull in both directions but it is evident that these political variables will influence the gas pricing in the international market to a large extent and thereby also the future internal natural gas market

  20. 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

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

    Natural gas is a promising alternative fuel to meet strict engine emission regulations in many countries. Natural gas engines can operate at lean burn and stoichiometric conditions with different combustion and emission characteristics. In this paper, the operating envelope, fuel economy, emissions, cycle-to-cycle variations in indicated mean effective pressure and strategies to achieve stable combustion of lean burn natural gas engines are highlighted. Stoichiometric natural gas engines are briefly reviewed. To keep the output power and torque of natural gas engines comparable to those of their gasoline or Diesel counterparts, high boost pressure should be used. High activity catalyst for methane oxidation and lean deNOx system or three way catalyst with precise air-fuel ratio control strategies should be developed to meet future stringent emission standards

    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

  7. Venezuela natural gas outlook

    Silva, P.

    1991-01-01

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

  8. The European natural gas market

    Hagland, Jan

    2001-01-01

    An increasing amount of natural gas is flowing into continental Europe, one of the largest gas markets in the world. There are three main sources of gas: Africa, Russia and Norway. Norway is an important supplier of gas, but may be vulnerable to competition. The demand for gas is increasing on a global basis and the largest increase is expected in Asia, followed by America and Europe. It is expected that Norwegian gas deliveries will be a principle source of natural gas for North Europe in the next years and that they will take an increasing part of the British market as the gas deliveries from the British shelf is going down. The European gas market is likely to become liberalized according to the EU's competition- and gas directives. This will not necessarily be a problem, and Norway may be able to increase the export of gas to Great Britain considerably from the year 2010, perhaps up to 40 billion standard m3 per year. Russia is expected to take an increased share of the European gas market, especially in East- and Central Europe, Germany and North Italy. But large investments in existing fields, new developments and new strategic pipelines are necessary

    The strategy of restricting natural gas to noble uses (directive of EEC and endorsed by the IEA) impeded gas expansion despite substantial upward revisions in the assessment of available resources. However, increasing environmental concern slowly but gradually undermines this strategy because natural gas serves as a substitute for costly abatement. This article discusses the prospect of future natural gas consumption considering economic and ecological facts as well as strategic and political considerations. In fact, we argue that inconsistent political interventions first seriously lowered gas penetration but now favor its use

    2018-04-01

    Full Text Available Natural gas consumption has increased with an average annual growth rate of about 10% between 2012 and 2017. Total natural gas consumption accounted for 6.4% of consumed primary energy resources in 2016, up from 5.4% in 2012, making China the world’s third-largest gas user. Therefore, accurately predicting natural gas consumption has become very important for market participants to organize indigenous production, foreign supply contracts and infrastructures in a better way. This paper first presents the main factors affecting China’s natural gas consumption, and then proposes a hybrid forecasting model by combining the particle swarm optimization algorithm and wavelet neural network (PSO-WNN. In PSO-WNN model, the initial weights and wavelet parameters are optimized using PSO algorithm and updated through a dynamic learning rate to improve the training speed, forecasting precision and reduce fluctuation of WNN. The experimental results show the superiority of the proposed model compared with ANN and WNN based models. Then, this study conducts the scenario analysis of the natural gas consumption from 2017 to 2025 in China based on three scenarios, namely low scenario, reference scenario and high scenario, and the results illustrate that the China’s natural gas consumption is going to be 342.70, 358.27, 366.42 million tce (“standard” tons coal equivalent in 2020, and 407.01, 437.95, 461.38 million tce in 2025 under the low, reference and high scenarios, respectively. Finally, this paper provides some policy suggestions on natural gas exploration and development, infrastructure construction and technical innovations to promote a sustainable development of China’s natural gas industry.

    This report sunnnarizes the research by an Energy Modeling Forum working group on the evolution of the North American natural gas markets between now and 2010. The group's findings are based partly on the results of a set of economic models of the natural gas industry that were run for four scenarios representing significantly different conditions: two oil price scenarios (upper and lower), a smaller total US resource base (low US resource case), and increased potential gas demand for electric generation (high US demand case). Several issues, such as the direction of regulatory policy and the size of the gas resource base, were analyzed separately without the use of models.

  16. The efficiency of natural gas futures markets

    International Nuclear Information System (INIS)

    Mazighi, A.E.H.

    2003-01-01

    Recent experience with the emergence of futures markets for natural gas has led to many questions about the drivers and functioning of these markets. Most often, however, studies lack strong statistical support. The objective of this article is to use some classical statistical tests to check whether futures markets for natural gas (NG) are efficient or not. The problem of NG market efficiency is closely linked to the debate on the value of NG. More precisely, if futures markets were really efficient, then: 1) spot prices would reflect the existence of a market assessment, which is proof that speculation and the manipulation of prices are absent; 2) as a consequence, spot prices could give clear signals about the value of NG; and 3) historical series on spot prices could serve as ''clean'' benchmarks in the pricing of NG in long-term contracts. On the whole, since the major share of NG is sold to power producers, the efficiency of futures markets implies that spot prices for NG are driven increasingly by power prices. On the other hand, if futures markets for natural gas fail the efficiency tests, this will reflect: 1) a lack of liquidity in futures markets and/or possibilities of an excess return in the short term; 2) a pass-through of the seasonality of power demand in the gas market; 3) the existence of a transitory process, before spot markets become efficient and give clear signals about the value of NG. Using monthly data on three segments of the futures markets, our findings show that efficiency is almost completely rejected on both the International Petroleum Exchange in London (UK market) and the New York Mercantile Exchange (US market). On the NYMEX, the principle of ''co-movement'' between spot and forward prices seems to be respected. However, the autocorrelation functions of the first differences in the price changes show no randomness of price fluctuations for three segments out of four. Further, both the NYMEX and the IPE fail, with regard to the

  17. Liquefied natural gas storage at Ambergate

    1970-08-19

    Ambergate works was planned in 1965-1966 and the decision was taken to install 4 ICI lean gas reformers using natural gas as feedstock, fuel, and enrichment. To cover the possible failure of natural gas supplies, petroleum distillate would be used as alternative feedstock and fuel. The choice for alternative enrichment lay between LPG or LNG. Since LNG would provide peak-on-peak storage facilities for either the East Midlands Board or the Gas Council when conversion was completed--and in the meantime would provide an additional source of LNG for local requirements when temporary LNG installations were used during conversion--agreement was reached with the Gas Council for it to build a 5,000-ton storage installation at Ambergate. The installation consists of 3 major sections: (1) the offloading bay and storage tank; (2) the reliquefaction system; and (3) the export system. The offloading bay and storage tank are for the reception and storage of liquefied Algerian natural gas, delivered to Ambergate by road tanker from the Canvey Is. Terminal. The reliquefaction system is to maintain the necessary storage tank conditions by reliquefying the boil-off natural gas. The export system delivers LNG from the storage tank at high pressure through a vaporization section in the national methane grid.

    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

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

    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

    Many consider natural gas to be the fuel of choice for the future because it is abundant, clean and cost competitive. This presentation reviewed how gas markets are changing in terms of globalization, the critical role of liquefied natural gas (LNG), the politics, technology and how the evolution will differ from oil. Other topics of discussion included the expanding world trade of LNG, LNG markets, supply countries, LNG flows in 2002 and potential future flows. Developments in the market were reviewed with reference to limited LNG spot market, mix of contract types, and the role of powerful aggregator partners. The impact of joining suppliers and markets was also discussed along with the value chain of the tramline model. Shell's LNG shipping position was outlined. Shell wholly owns 4 LNG ships and partly owns and operates 16 more ships. The presentation listed existing, permitted, publicly announced and scouting LNG regas terminals in North America, along with Shell interests. It was noted that LNG has the potential to meet some of the growing deficit in North American gas production. The issues that require consideration include permitting uncertainties, basis risk, impact of imports on basis, expansion possibilities, constraints on pipeline infrastructure, marketing capabilities, global supply issues and finance possibilities. figs

    1992-10-01

    The development of Natural Gas Vehicles is progressing rapidly under the stimulus of recent vehicle emission regulations. The development is following what can be viewed as a three step progression. In the first step, contemporary gasoline or diesel fueled automobiles are retrofitted with equipment enabling the vehicle to operate on either natural gas or standard liquid fuels. The second step is the development of vehicles which utilize traditional internal combustion engines that have been modified to operate exclusively on natural gas. These dedicated natural gas vehicles operate more efficiently and have lower emissions than the dual fueled vehicles. The third step is the redesigning, from the ground up, of a vehicle aimed at exploiting the advantages of natural gas as an automotive fuel while minimizing its disadvantages. The current report is aimed at identifying the R&D needs in various fuel storage and engine combinations which have potential for providing increased efficiency, reduced emissions, and reductions in vehicle weight and size. Fuel suppliers, automobile and engine manufacturers, many segments of the natural gas and other industries, and regulatory authorities will influence or be affected by the development of such a third generation vehicle, and it is recommended that GRI act to bring these groups together in the near future to begin, developing the focus on a 'designed-for-natural-gas' vehicle.

  8. Natural gas supply strategies for European energy market actors

    Girault, Vincent

    2007-06-01

    The liberalization of the European energy markets leads to the diversification of supplies. Hence, we analyse the natural gas importation problem in a power producer point of view. Upstream and downstream natural gas markets are concentrated. In this oligopoly context, our topic is to focus on strategies which modify natural gas sourcing price. This by studying the surplus sharing on the natural gas chain. A European firm can bundle gas and electricity outputs to increase its market share. Therefore, a bundling strategy of a power producer in competition with a natural gas reseller on the final European energy market increases upstream natural gas price. Bundling also acts as a raising rival cost strategy and reduces the rivals' profit. Profits opportunities incite natural gas producers to enter the final market. Vertical integration between a natural gas producer and a European gas reseller is a way, for producers, to catch end consumer surplus. Vertical integration results in the foreclosure of the power producer on the upstream natural gas market. To be active on the natural gas market, the power producer could supply bundles. But, this strategy reallocates the rent. The integrated firm on natural gas gets the rent of electricity market in expenses of the power producer. Then, a solution for the power producer is to supply gas and electricity as complements. Then, we consider a case where vertical integration is not allowed. Input price discrimination by a monopolist leads to a lower natural gas price for the actor which diversifies its supplying sources. Furthermore, a bundling strategy increases the gap between the price proposed to the firm which also diversify its output and the firm which is fully dependent from the producer to supply natural gas on final market.

    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.

    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.

    2011-01-01

    This article presents a dynamic Generalized Nash-Cournot model to describe the evolution of the natural gas markets. The major players along the gas chain are depicted including: producers, consumers, storage and pipeline operators, as well as intermediate local traders. Our economic structure description takes into account market power and the demand representation tries to capture the possible fuel substitution that can be made between the consumption of oil, coal, and natural gas in the overall fossil energy consumption. We also take into account long-term contracts in an endogenous way, which makes the model a Generalized Nash Equilibrium problem. We discuss some means to solve such problems. Our model has been applied to represent the European natural gas market and forecast, until 2030, after a calibration process, consumption, prices, production, and natural gas dependence. A comparison between our model, a more standard one that does not take into account energy substitution, and the European Commission natural gas forecasts is carried out to analyze our results. Finally, in order to illustrate the possible use of fuel substitution, we studied the evolution of the natural gas price as compared to the coal and oil prices. (authors)

  16. Natural gas industry and its effects on the environment

    The discoveries of natural gas have increased during the last ten years in Syria, These increases lead to the necessity of knowing the effects of this industry on the environment. Syrian Arabic Republic has been planning to convert most of the current electric of plants to natural gas in addition to future plans to export natural gas to the surrounding countries. In addition, the government is working on the use of LPG gas in automobiles. However, environmentally, the importance of natural gas is due to the followings: 1- Natural gas, when burned, emits lower quantities of greenhouse gases and criteria pollutants per unit of energy produced than to other fossil fuels. This occurs in part because natural gas is more fully combusted, and in part because natural gas contains fewer impurities than any other fossil fuel. 2-The amount of carbon dioxide produced from the combustion of natural gas is less than the amount produced from the combustion of other fossil fuels to produce the same amount of heat. One of the important uses of natural gas is in the transportation since natural gas does not produce during combustion toxic compounds which are usually produced during the combustion of diesel and benzene. therefore natural gas is seen and considered as an important fuel to address environmental concerns.

  17. Natural gas market assessment ten years after deregulation

    International Nuclear Information System (INIS)

    1996-11-01

    Changes which have taken place in the Canadian natural gas market in the ten years since the gas market was de-regulated, were reviewed. A 1985 agreement created conditions for a competitive natural gas market. However, the National Energy Board ensured that the pipeline transmission sector of the gas industry would continue to be regulated because of its natural monopoly characteristics. Open non-discriminatory access was to be provided to all shippers on inter-provincial gas pipelines. One objective of this report was to provide the Board with the means of assuring itself that the market was operating in such a way that Canadian requirements for natural gas were being met at fair market prices. The report also provided a review of the major changes in the gas producing and transmission sector, and reviewed developments in gas markets and sales practices. The overall assessment was that the natural gas industry was efficient and responsive to the demands of the marketplace. 5 tabs., 30 figs

    1965-08-01

    In 1948, the first natural gas was found in Netherlands. Since 1951 it has been supplied by gas undertakings. Originally reserves were limited (c. 350 milliard ftU3D of dry gas in the NE. and c. 175 milliard ftU3D, mostly wet gas, in the SW). These finds have been completely overshadowed by the huge deposits discovered in 1960 in the province of Groningen near the village of Slochteren, these reserves being estimated now at 38.5 billion ftU3D at least. This gas is not of high cal val (894 Btu/ftU3D), but contains only traces of sulfur. The concession is being developed for a partnership formed by Shell (30%), Standard Oil Company of new Jersey (Esso, 30%), and ''Staatsmijnen,'' the Government owned Netherlands State Mining Industry (40%). The natural gas is destined, first, for domestic use, especially, for space heating, and secondly, for industrial purpose, after which important quantities will be available for export.

    This paper tables numerous statistical data to evidence that whereas the use of natural gas as an automotive fuel for private and public vehicles is growing in Asia, North and South America, in Europe this trend is currently being followed only in Italy. However, with the relatively recent expansion of the European Communities' natural gas distribution network, coupled with growing interest in this fuel as a cost effective and environmentally compatible alternative to petroleum, the demand for natural gas automotive fuels is expected to increase even in this continent. The trucking industry in particular should derive significant benefits from the switch to natural gas

    We provide the first high-frequency investigation of price discovery within the physical and financial layers of Europe's natural gas markets. Testing not only looks at short-term return dynamics, but also considers each security's contribution to price equilibrium in the longer-term. Results show that UK natural gas futures traded on the Intercontinental Exchange display greater price discovery than physical trading at various hubs throughout Europe. - Highlights: • We use intraday data to gauge price discovery in European natural gas markets. • We explore short and long-term dynamics in physical and financial market layers. • Results show ICE's UK natural gas futures are the main venue for price discovery

    The objective of this article is to present the structuring of a port directing plan for the liquefied natural gas. In this sense, an integrated approach between the applied logistic and the requested market conditions was used. For the large distances transportation of liquefied natural gas, the marine modal must attain technical requirements that are not usual in the port routine. Apart from the proper dimensioning of the naval fleet in order to maximize the transported load, providing the optimization of the economic distance, the entire port infra-structure is planned for the reception of liquefied natural gas, in order to attend the physical peculiarities as well as security aspects of extreme importance. The selection of the studied local was motivated by the fuel supply shortage suffered by the country, especially in the northeast region, which owns already installed thermal units in need of the fuel supply to be operated.

    Studies have shown that the demand for crude oil exceeds supply and other energy sources are needed to met the shortfall. Natural gas and coal are the only 2 current energy sources that have the global capacity to, by themselves, address increased energy demand in a timely manner. Both these resources have been used primarily for power generation and heating. This paper discussed the transition that will likely occur in which natural gas and coal will be used increasingly as transportation fuels. It presented data comparing the environmental impact of using methane versus coal and proposed natural gas as the future green fuel. A strengths, weaknesses, opportunities and threats (SWOT) analysis was conducted to obtain a better understanding of the current Canadian natural gas market. The strengths include recent discoveries in the Horn River Basin and the Montney plays in British Columbia which are expected to triple natural gas production within the next decade. The weaknesses include an oversupply of gas compared to current demand; gas prices are currently in a range that are barely economic for many shale plays; and Canadian gas is disadvantaged for sales in the United States by additional pipeline transportation costs. The opportunities include global export opportunities of liquefied natural gas (LNG) through the proposed Kitimat LNG export facility and others off the west coast of Canada. The threat facing natural gas development is the strong competition for market share with coal. However, emissions data and energy efficiencies provide evidence to support the choice to use natural gas. 5 refs., 2 tabs., 26 figs.

    2004-01-01

    This paper outlines the impact of environmental policy on natural gas demand and describes alternative energy sources such as wind, solar, biomass and clean coal that can increase energy supplies. This briefing also establishes the short-, medium-, and long-term consequences of current natural gas realities. It also outlines the driving forces in Canada and the United States behind the demand for natural gas. The impact of policy formation and the phase-out of coal in Ontario are addressed along with natural gas supply prospects and the prospects and obstacles for riskier incremental supplies such as liquefied natural gas, natural gas from coal, and frontier natural gas. It was concluded that strong demand and tight supply are the factors that have driven up natural gas prices. Continued high natural gas prices in the short term will likely motivate conservation strategies at the personal household level as well as in the business and industrial sectors. Although wind power is seen as a clean, competitively prices alternative to natural gas-fired electricity generation, its contribution is not expected to change the supply and demand equilibrium. Initiatives such as the Mackenzie Valley Pipeline, the Alaskan Pipeline and drilling in the Atlantic may help balance natural gas supply and demand in the mid-term. 44 refs., 2 tabs., 7 figs

    1989-11-01

    The present situation on price transparency in Western Europe and North america within the context of the European internal gas market is analyzed. In chapter one the ideas and policy proposals put forward by the European Commission are discussed. Special attention is paid to the situation of the large industrial consumers. It is argued that price transparency needs to be extended to more upstream price aspects. This includes information on city-gates prices, transmission and handling charges in addition to wellhead and import prices. In Western Europe (chapter two) two pricing principles can be distinguished at the final consumer level: pricing according to costs and prices according to market value. The first principle is applied in France, Belgium, the United Kingdom and Austria, as some cost elements are included in the tariff calculations in Italy. Countries where a market-evaluation methodology is applied are Denmark, the Netherlands, Germany, Spain and Switzerland. In North America (chapter three) price transparency is extensive and part of the necessary conditions of an open access contract carriage market. In order to integrate the aspect of price transparency in the broader framework of the internal gas market a model of an integrated natural gas market is described in chapter four. The model specifies the preconditions of a truly integrated gas market, i.e. accessible market entry at all levels of the gas sector and for all market players, equal market opportunity and a regulatory oversight system. A brief comparison between the model and the actual market situation in Western Europe showed that hardly any of these preconditions are met. The comparison points out which actions need to be taken to implement an internal gas market in Western Europe. 9 appendices

    Indonesia imports high amount of Fuel Oil. Although Indonesia has abundant amount of natural gas reserve, the obstacle lies within the process of natural gas storage itself. In order to create a safe repository, the ANG (Adsorbed Natural Gas) technology is planned. ANG technology in itself has been researched much to manufacture PET-based activated carbon for natural gas storage, but ANG still has several drawbacks. This study begins with making preparations for the equipment and materials that will be used, by characterizing the natural gas, measuring the empty volume, and degassing. The next step will be to examine the adsorption process. The maximum storage capacity obtained in this study for a temperature of 27°C and pressure of 35 bar is 0.0586 kg/kg, while for the desorption process, a maximum value for desorption efficiency was obtained on 35°C temperature with a value of 73.39%.

    Natural gas was for a long time reserved to the most noble uses in the industry. However, natural gas, which get a priori no captive market, has progressively imposed itself in all possible energy uses. The gas resources and abundant enough to represent the main contribution of the energy industry of the 21 century. With intrinsic qualities which make it an energy less polluting than the other fossil fuels, natural gas is the commercial energy source with the highest potential growth in the energy status of the future.

    Natural gas is extracted in nearly 80 countries, 12 of which have a share of four fifths in the world extraction and 15 of which have a share of four fifths in the world consumption. The natural-gas world reserves can cover the present annual demand for years beyond the middle of the coming century. According to current assessments, the resources which presently cannot be extracted economically, the expected additional resources, and the extractable share in the potential of unconventional natural gas amount to more than ten times the reliable world reserves of natural gas. From the geological and technical points of view the world natural-gas extraction will not decrease or cease in the near future. However, the more expensive development of unconventional deposits which are located far away from the end-user will have to be preferred over the medium term on account of the exhaustion of the known deposits whose exploitation is comparatively cheap.

    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

    By reviewing the statistics of BP Amoco on natural gas reserves, production and usage, it is easy to see that Russia and USA, both being large natural gas producers, differ significantly from each other. The natural gas reserves of USA are 6th largest in the world, simultaneously the natural gas consumption and import are largest in the world. About one third of the known natural gas reserves of the world are in Russia. The known natural gas reserves of both USA and Canada have decreases, but they have potential gas reserves left. Known natural gas reserves of the USA have been calculated to be sufficient for 9 years consumption at present usage and those of Canada for 11 years. The reserves of Algeria correspond to the usage of 55 years, and the Russian reserves for are about 83 years. Annual production figures of both Russia and the USA are nearly the same. Russia is the largest exporter (125.5 billion m 3 ) of natural gas and the USA the largest importer (96 billion m 3 ). The natural gas reserves of the largest European producers, the Netherlands and Norway have been estimated to be sufficient for use of about 20 years, but those of Great Britain only for about 10 years. The annual production of Russia has varied in the 1990s between nearly 600 billion m 3 and present 550 billion m 3 , the minimum being in 1997 only about 532 billion m 3 . Ten largest natural gas consumers use 67% of the natural gas consumed annually in the world. USA consumes about 27% of the total natural gas produced in the world, the amount of Russia being 364 billion m 3 (16%). Other large natural gas consumers are Great Britain, Germany, Japan, Ukraine, Canada, Italy, Iran and Uzbekistan. The share of these countries of the total consumption varied in between 2-4%. Only Japan has no natural gas production of its own. The foreign trade between Japan and Indonesia is trade on LNG. On the other hand the natural gas consumption of the world's 10th largest producer Norway is nearly zero, so

    Great are the challenges established by the Brazilian Government related to goals to be achieved for the increment of the Natural Gas participation in brazilian energetic matrix, from current 5% to 12%, up to 2010. The enlargement of the distribution infrastructure of the gas (gas-pipelines 'mesh') in Brazil is considered one of the greatest challenges for the growth of the Brazilian market of Natural Gas, accomplishment that involves elevated investments. This paper presents a model of Management System for the good organizational performance of the small Natural Gas Supplying Brazilian Companies focused on criteria of Leadership, Strategies and Plans and Results, established by the Premio TOP Empresarial and by the 'Rumo a Excelencia', held by the 'Progama Qualidade Rio' and 'Fundacao para o Premio Nacional da Qualidade', respectively. The management practices of these companies were reviewed, considering the context of the energetic Brazilian scenario, subjected to the political and operational definitions and uncertainties, the available financial resources, limited or not prioritized, and actual barriers to be surpassed by the Gas Supplying Companies in order to achieve the pre-established government goals for this segment. The implementation of the proposed simplified Model, seen as improvement opportunities for the segment of Natural Gas distribution, will lead the Gas Distribution Companies to a intermediary stage envisioning the real steps towards the excellence of the performance.

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

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

    Natural gas is considered as a preferred fuel and its utility is growing every day in the country (Iran). The usage of natural gas has increased from 3.5 to 44 billion cubic meters from 1980 to 1997, respectively. Currently, 4 million residences and most of the industrial sector are being provided with the pipelined natural gas. Because of the tremendous increase in consumption, it is necessary to give the needed considerations to natural gas rate structure. The objective of the paper is to 1.Evaluate the fundamentals and principal methods used for rate structures. 2. Identification of effective components. 3. Analyze the current rates including connection fees and other customer charges

    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

  3. Committing to coal and gas: Long-term contracts, regulation, and fuel switching in power generation

    Science.gov (United States)

    Rice, Michael

    Fuel switching in the electricity sector has important economic and environmental consequences. In the United States, the increased supply of gas during the last decade has led to substantial switching in the short term. Fuel switching is constrained, however, by the existing infrastructure. The power generation infrastructure, in turn, represents commitments to specific sources of energy over the long term. This dissertation explores fuel contracts as the link between short-term price response and long-term plant investments. Contracting choices enable power plant investments that are relationship-specific, often regulated, and face uncertainty. Many power plants are subject to both hold-up in investment and cost-of-service regulation. I find that capital bias is robust when considering either irreversibility or hold-up due to the uncertain arrival of an outside option. For sunk capital, the rental rate is inappropriate for determining capital bias. Instead, capital bias depends on the regulated rate of return, discount rate, and depreciation schedule. If policies such as emissions regulations increase fuel-switching flexibility, this can lead to capital bias. Cost-of-service regulation can shorten the duration of a long-term contract. From the firm's perspective, the existing literature provides limited guidance when bargaining and writing contracts for fuel procurement. I develop a stochastic programming framework to optimize long-term contracting decisions under both endogenous and exogenous sources of hold-up risk. These typically include policy changes, price shocks, availability of fuel, and volatility in derived demand. For price risks, the optimal contract duration is the moment when the expected benefits of the contract are just outweighed by the expected opportunity costs of remaining in the contract. I prove that imposing early renegotiation costs decreases contract duration. Finally, I provide an empirical approach to show how coal contracts can limit

    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)

  5. The natural gas guideline... Finally a good agreement

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

    In 2004 a study was published on green gas. Green gas is defined as a gaseous energy carrier from renewable biomass with a similar quality as natural gas. As a result of new developments in the field of co-digestion/fermentation the Dutch Ministry of Economic Affairs asked it's agency SenterNovem to update the 2004 study. The aim of the update is (1) to gain insight into operational aspects of green gas projects, e.g. reliability, efficiency and maintenance aspects; (2) stimulate the production of green gas, taking into account the economics of green gas projects, calculation of the financial gap of green gas production, efficient use of biogas (conversion to electricity or directly input into the natural gas distribution systems, and aspects with regard to commercialization and the market; and (3) the potential of green gas [nl

  7. Natural gas - bridge to a clean energy future

    1991-01-01

    Per unit of useful energy natural gas gives the lowest environmental pollution of all fossil fuels. This is due to its low carbon content, the absence of sulphur compounds, and the fact that natural gas can, rather easily, be burnt completely in such a way that also the NO x emission is acceptably low. Although natural gas has already a good record as an efficient and clean fuel large improvements are still possible, but this requires more R+D and time. The presently known natural gas world reserves are high enough to go for a substantially higher share of gas in the energy package. E.g. replacing coal by natural gas will give large environmental improvements. Furthermore, direct gas use is very often the most efficient and cleanest option, also when electricity is an alternative. To develop and connect the known large reserves to the market enormous amounts of money are required. The political and economical situation should make these investments possible and attractive. The ideas first expressed by the Dutch prime minister, now incorporated in the Energy Charter, have been developed to that end. Special attention should be given to the development of small gas fields as is e.g. being done in The Netherlands, which has improved the local gas reserves situation impressively. As a first major step to a clean future the potential of natural gas should be explored and put to work worldwide. Its potential as an important diversified source of energy is underestimated. Amongst others by funding more natural gas R+D natural gas should develop a keyrole in the energy scene of the next 3-5 decades.(author) 3 figs., 8 tabs., 3 refs

    1992-01-01

    After first relating the importance of natural gas storage to the viability of Italian industrial activities, this paper discusses the geo-physical nature of different types of underground cavities which can be used for natural gas storage. These include depleted petroleum and natural gas reservoirs, aquifers and abandoned mines. Attention is given to the geologic characteristics and physical characteristics such as porosity, permeability and pressure that determine the suitability of any given storage area, and to the techniques used to resolve problems relative to partially depleted reservoirs, e.g., the presence of oil, water and salt. A review is made of Italy's main storage facilities. This review identifies the various types of storage techniques, major equipment, operating and maintenance practices. A look is then given at Italy's plans for the development of new facilities to meet rising demand expected to reach 80 billion cubic meters/year by the turn of the century. The operating activities of the two leading participants, SNAM and AGIP, in Italy's natural gas industry are highlighted. Specific problems which contribute to the high operating costs of natural gas storage are identified and a review is made of national normatives governing gas storage. The report comes complete with a glossary of the relative terminology and units of measure

    Full Text Available The world today recognizes the significance of environmental sustainability to the development of nations. Hence, the role oil and gas industry plays in environmental degrading activities such as gas flaring is of global concern. This study presents material balance equations and predicts results for non-hydrocarbon emissions such as CO2, CO, NO, NO2, and SO2 etc. from flaring (combustion of 12 natural gas samples representing composition of natural gas of global origin. Gaseous emission estimates and pattern were modelled by coding material balance equations for six reaction types and combustion conditions with a computer program. On the average, anticipated gaseous emissions from flaring natural gas with an average annual global flaring rate 126 bcm per year (between 2000 and 2011 in million metric tonnes (mmt are 560 mmt, 48 mmt, 91 mmt, 93 mmt and 50 mmt for CO2, CO, NO, NO2 and SO2 respectively. This model predicted gaseous emissions based on the possible individual combustion types and conditions anticipated in gas flaring operation. It will assist in the effort by environmental agencies and all concerned to track and measure the extent of environmental pollution caused by gas flaring operations in the oil and gas industry.

    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.

    Natural gas has a very good potential compared to other fossil fuels as regard to global warming because of its high content of hydrogen, and its versatility in uses. To take full advantage of this potential, further development of gas designed boilers and furnaces, gas catalytic combustion, fuel cells are needed, but progresses in the recent years have been very promising. The natural gas industry' environmental potential is discussed. Regarding methane emission, progresses have been done is Western Europe on the distribution network, and some improvement are underway. It is however important to rationalize the effort by acting on the most emitting subsystem: this can be achieved by cooperation along the whole gas chain. (R.P.)

    The efficient and effective movement of natural gas from producing regions to consuming regions requires an extensive and elaborate transportation system. In many instances, natural gas produced from a particular well has to travel a great distance to reach its point of use. The transportation system for natural gas consists of a complex network of pipelines designed to quickly and efficiently transport the gas from its origin to areas of high demand. The transportation of natural gas is closely linked to its storage: If the natural gas being transported is not immediately required, it can be put into storage facilities until it is needed. A description of the natural gas transmission, storage, and distribution (TS&D) sector is provided as follows.

    Highlights: ► Stochastic price-based unit commitment (PBUC) for a generation company (GENCO). ► Water inflow, wind, and NG interruption uncertainties are considered. ► Diversification of assets and bilateral contracts enhance payoff and decrease financial risk. ► The utilization of NG in the risk-neutral GENCO case increases as the wind uncertainty increases. ► NG utilization is lowered by the algorithm to decrease in risk-considered case. -- Abstract: This paper studies a generating company (GENCO)’s midterm (a few months to a year) scheduling payoffs and risks in volatile operating conditions. The proposed algorithm considers the integration of intermittent wind units into a GENCO’s generation assets and coordinates the GENCO’s hourly wind generation schedule with that of natural gas (NG) units (with volatile gas prices) and hydro units (with water inflow forecast) for maximizing the GENCO’s payoff. The proposed midterm GENCO model applies market price forecasts to the risk-constrained stochastic price-based unit commitment (PBUC) for calculating the GENCO’s risk in energy and ancillary services markets. The proposed PBUC minimizes the cost of (a) NG contracts, storage, startup and shutdown, (b) startup and shutdown of cascaded hydro units, and (c) penalty for defaulting on the scheduled power delivery. Simulation results show that the diversification of generating assets including bilateral contracts (BCs) could enhance the GENCO’s midterm planning by increasing the expected payoff and decreasing the financial risk.
