{"title":"Innovative Energy Solutions-Shale Gas In India","authors":"Vidhu Gupta","doi":"10.2139/ssrn.3710412","DOIUrl":"https://doi.org/10.2139/ssrn.3710412","url":null,"abstract":"Shale gas is a major domestic option for natural gas of a country where conventional gas reserves had been used up. It is entrapped in between shale formations, having low permeability that makes its commercial production extremely difficult. Major constituent is methane which is utilized for synthesizing Ammonia and Methanol. Natural Gas Liquids (NGLs) constituents such as Ethane, Propane and Butane are utilized for Ethylene synthesis. Ethylene synthesized by Shale gas is preferred over that of manufactured by Naphtha.CO2, N2 and H2S are small fraction non-hydrocarbon constituents. Production of shale gas had lowered the dependency of nations to Middle-east for their energy needs but shale production comes at a high cost of environment degradation. About 3% of extracted gas is being released in the atmosphere, fracturing of underlying rocks can induce small earthquakes and quick exhaustion of shale wells in comparison to conventional gas wells are major disadvantages. Fracking fluid being used for Hydraulic Fracking consists of large quantities of water, sand and chemicals. After the process, vital fractions of it left underground can possibly pollute underground water sources. A long term study of the process is still desired in order to reveal exact intricacies of Environment Contamination. \u0000 \u0000A Shaft is drilled into the ground up to the depth of gas bearing layer Fracking fluid is then pumped using high performance pumps. Fluid mixture penetrates into the rock layer and produces innumerable tiny cracks. Water acts as solvent, sand holds up the opening, Chemicals condense water, kill off bacteria and dissolve minerals. Production of shale gas then begins. After the reserve is exhausted, some amount of fracking fluid is pumped in again and then the drill hole is sealed. \u0000 \u0000A general observed fact is that in every hydrocarbon producing nation there is an equal likelihood regarding the presence of shales holding hydrocarbons. As published in the report of EIA, June 2013 amount of shale gas resources in India is 584 tcf and the technically recoverable amount is about 96 tcf (Cambay, Krishna-Godavari, Cauvery, Damodar Valley, Upper Assam, Pranhita-Godawari, Rajasthan and Vindhyan basins). \u0000 \u0000Vital task before shale gas production includes the ultimate analysis of geological properties of shales in order to produce gas/oil from them. In this regard, government with the support of many private agencies had drilled several thousand wells (mainly in Cambay, KG and Cauvery basins).These wells had provided extensive data on extent, depth and nature of shale formations in sedimentary basins. However, a lot of work is still left to actually start commercial production of shale gas on Indian soil.","PeriodicalId":244835,"journal":{"name":"EnergyRN: Unconventional Gas (Sub-Topic)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134357702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The Unconventional Oil Supply Boom: Aggregate Price Response from Microdata","authors":"R. Newell, Brian C. Prest","doi":"10.5547/01956574.40.3.rnew","DOIUrl":"https://doi.org/10.5547/01956574.40.3.rnew","url":null,"abstract":"We analyze the price responsiveness of onshore oil supply from conventional versus new unconventional \"tight\" formations in the United States. We separately analyze three key stages of oil production: drilling wells, completing wells, and production from completed wells. We find that the important margin is drilling investment. We estimate drilling responses of approximately 1.6 percent for tight oil and 1.2 percent for conventional oil per 1 percent change in oil prices. In addition, tight oil wells produce about 4.6 times more oil compared to conventional ones. Together, the long-run price responsiveness of supply is about 6 times larger for tight oil on a per well basis, and about 9 times larger when also accounting for the rise in unconventional-directed drilling. Based on our estimates derived from microdata, we conduct aggregate simulations of incremental oil supply at different time frames and price levels. The simulations show that the U.S. supply response is much larger now due to the shale revolution. Given a price rise to $80 per barrel, U.S. oil production could rise by 0.5 million barrels per day in 6 months, 1.2 million in 1 year, 2 million in 2 years, and 3 million in 5 years. Nonetheless, it takes many months before a substantial portion of the full supply response is online, longer than the 30 to 90 days typically associated with the role of \"swing producer\" such as Saudi Arabia.","PeriodicalId":244835,"journal":{"name":"EnergyRN: Unconventional Gas (Sub-Topic)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127951040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using novel data on inputs, profits, and information sets, I study how oil companies learned to use hydraulic fracturing technology in North Dakota between 2005-2012. Firms only partially learned to make profitable input choices, capturing just 60% of possible profits in 2012. To understand why, I estimate a model of input use under technology uncertainty. Firms chose fracking inputs with higher expectations but lower uncertainty about profits, consistent with passive learning but not active experimentation. Most firms over-weighed their own information. These results provide evidence of impediments to learning.","PeriodicalId":244835,"journal":{"name":"EnergyRN: Unconventional Gas (Sub-Topic)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114712141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
