This book was released on 2012-03 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underground gas storage (UGS) involves storage of large quantities of natural gas in a storage horizon to support the natural gas demand in domestic, commercial, and industrial areas. The main objectives of this book are to investigate the possibility of (UGS) development and feasibility of underground sour gas storage in a depleted fractured gas reservoir. Compositional simulation was employed to build a dynamic reservoir model, develop the history-matching phase of the reservoir, and construct injection/withdrawal (I/W) cycles. A systematic procedure was employed to determine optimum well pattern (well number, location, horizontal, vertical). Simulation study specified that the use of horizontal well is superior to vertical well because of less water production during storage cycles. Water cut, productivity and injectivity indexes of individual wells were considered as prominent factors to find the optimum well pattern. The results of the simulation showed that the presence of H2S and CO2 in the injected gas stream improved condensate production. It was found that UGS reservoir meet lower pressure at the end of I/W cycles in the case of underground sour gas storage.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of NATO Advanced Study Institute, 'Underground Storage of Natural Gas - Theory and Practice', which was held at The Middle East Technical University, Ankara, Turkey during 2-10 May 1988. Underground storage is the process which effectively balances a variable demand market with a desirably constant supply provided by pipelines. Storage reservoirs are the unique warehouses designed and developed to provide a ready supply of natural gas in response to high, peak demands during cold weather. The natural' gas is injected into the underground storage environment when the market demand falls below the supply available from the pipeline. It is withdrawn from the storage reservoir to supplement the steady supply provided by the pipelines whenever the demand exceeds the supply. The overall wellbeing of the entire western world in general and of the NATO member count ries in particular depend critically upon having sufficient energy resources. Of over 80 quad Btus of energy consumed each year in the western world, about 30~ comes from natural gas, a figure only exceeded by oil. The technology related to supply and demand of natural gas has been in the focus of long range energy planning during the last decade in Western Europe. In view of recent developments related to natural gas in Europe and Turkey, an "Advanced Study Institute" programme in Turkey on underground storage of natural gas was deemed particularly relevant and timely.

Available in PDF, EPUB and Kindle. Book excerpt: For a natural gas importing country, 3take or pay4 approach creates problems since the demand for natural gas varies during the year and the excess amount of natural gas should be stored. In this study, an underground gas storage project is evaluated in a depleted gas Field M. After gathering all necessary reservoir, fluid, production and pressure data, the data were adapted to computer language, which was used in a commercial simulator software (IMEX) that is the CMG2s (Computer Modelling Group) new generation adoptive simulator, to reach the history matching. The history matching which consists of the 4 year of production of the gas reservoir is the first step of this study. The simulation program was able to accomplish a good history match with the given parameters of the reservoir. Using the history match as a base, five different scenarios were created and forecast the injection and withdrawal performance of the reservoir. These scenarios includes 5 newly drilled horizontal wells which were used in combinations with the existing wells. With a predetermined injection rate of 13 MMcf/D was set for all the wells and among the 5 scenarios, 5 horizontal 6 6 vertical injectors & 5 horizontal - 6 vertical producers is the most successful in handling the gas inventory and the time it takes for a gas injection and production period. After the determination of the well configuration, the optimum injection rate for the entire field was obtained and found to be 130 MMcf/D by running different injection rates for all wells and then for only horizontal wells different injection rates were applied with a constant injection rate of 130 MMcf/d for vertical wells. Then it has been found that it is better to apply the 5th scenario which includes 5 horizontal – 6 vertical injectors & 5 horizontal - 6 vertical producers having an injection rate of 130 MMcf/d for horizontal and vertical wells. Since within the 5th scenario, changing the injection rate to 1.3 Bcf/d and 13 Bcf/d, did.

This book was released on 1989 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Base gas requirements in the U.S. amount to a few trillion cubic feet. The Gas Research Institute has proposed a gas storage operating plan whereby an inert gas or a low BTU gas could be injected to replace part of the hydrocarbon gas. A reservoir simulator has been developed, enhanced and tested to solve gas-water reservoir problems where the gas may be treated as a two-component miscible mixture. The previously developed reservoir simulator was further enhanced to include a local grid refinement option, which allows the engineer to study a portion of the field in more detail compared to the rest of the field. The simulator was tested for correctness and completeness. A simulation study was conducted for the Hanson Field Gas Storage Reservoir using two models with different layering. The reservoir history matching was duplicated and several prediction cases were run to study the effectiveness of the replacement of base gas with an inert gas. The results show that replacement of a portion of the hydrocarbon base gas with an inert gas can be an attractive alternative for the gas storage industry. with.

This book was released on 1990 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two causes of poor recoverability of gas stored in aquifers are migration of gas far from the injection well and upward coning of water into withdrawal wells. Laboratory experiments and numerical simulations were conducted to study the possible use of aqueous foams to block the flow of gas or liquid to ameliorate these problems. Experiments in sandstone cores at simulated reservoir conditions showed that foam reduces the permeability to gas and liquid by typically three orders of magnitude. The rheology of foam was also investigated. It was found that steady-state pressure gradients for foam are practically independent of gas velocity but increase nearly linearly with increasing liquid velocity. This flow behavior is rationalized in terms of changes in bubble texture. A numerical simulation study showed that water coning could be significantly delayed by placing a horizontal foam lens just above the gas-water interface. Also discussed in the report are conditions for forming foam in situ, the feasibility of emplacing a foam bank, and the durability of permeability reduction. Laboratory experiments and numerical simulation indicate the potential for significantly improving the efficiency of aquifer gas storage with aqueous foams. A field trial foam to diminish water coning is recommended.

Available in PDF, EPUB and Kindle. Book excerpt: The US Department of Energy (DOE), through partnerships with industry, is demonstrating the importance of geologic modeling and reservoir simulation for optimizing the development and operation of gas storage fields. The geologic modeling and reservoir simulation study for the Natural Fuel Gas Supply Corporation CRADA was completed in September 1995. The results of this study were presented at the 1995 Society of Petroleum Engineers' (SPE) Eastern Regional Meeting. Although there has been no field verification of the modeling results, the study has shown the potential advantages and cost savings opportunities of using horizontal wells for storage enhancement. The geologic modeling for the Equitrans' CRADA was completed in September 1995 and was also presented at the 1995 SPE Eastern Regional Meeting. The reservoir modeling of past field performance was completed in November 1996 and prediction runs are currently being made to investigate the potential of offering either a 10 day or 30 day peaking service in addition to the existing 110 day base load service. Initial results have shown that peaking services can be provided through remediation of well damage and by drilling either several new vertical wells or one new horizontal well. The geologic modeling for the Northern Indiana Public Service Company CRADA was completed in November 1996 with a horizontal well being completed in January 1997. Based on well test results, the well will significantly enhance gas deliverability from the field and will allow the utilization of gas from an area of the storage field that was not accessible from their existing vertical wells. Results are presented from these three case studies.

Available in PDF, EPUB and Kindle. Book excerpt: The UK became a net importer of natural gas in 2004 and by 2020 will import up to 90% of its requirements, leaving it vulnerable to increasing energy bills and risk of disruption to supply. New pipelines to Europe and improvements to interconnectors will meet some demand, but Government recognises the need for increased gas storage capacity: best met by the construction of underground storage facilities. Energy security has also raised the likelihood of a new generation of coal-fired power-stations, which to be environmentally viable, will require clean-coal technologies with near-zero greenhouse gas emissions. A key element of this strategy will be underground CO2 storage. This volume reviews the technologies and issues involved in the underground storage of natural gas and CO2, with examples from the UK and overseas. The potential for underground storage of other gases such as hydrogen, or compressed air linked to renewable sources is also reviewed.
