Study reveals how to improve natural gas production in shale
Because shales ordinarily have insufficient permeability to allow significant fluid flow to a wellbore, most shales are not commercial sources of natural gas. Shale gas is one of a number of unconventional sources of natural gas; others include coalbed methane, tight sandstones, and methane hydrates. … See more Shale gas is an unconventional natural gas that is found trapped within shale formations. Since the 1990s a combination of horizontal drilling and hydraulic fracturing has made large volumes of shale gas more economical to … See more Although the shale gas potential of many nations is being studied, as of 2013, only the US, Canada, and China produce shale gas in commercial … See more Drilling depths of 1,000 to 3,000 m, then injection of a fluid composed of water, sand and detergents under pressure (600 bar), are required … See more Although shale gas has been produced for more than 100 years in the Appalachian Basin and the Illinois Basin of the United States, the wells were often marginally economic. Advances in hydraulic fracturing and horizontal completions have made shale-gas wells … See more United States Shale gas was first extracted as a resource in Fredonia, New York, in 1821, in shallow, low-pressure fractures. Horizontal drilling began in the 1930s, and in 1947 a well was first fracked in the U.S. Federal price … See more The extraction and use of shale gas can affect the environment through the leaking of extraction chemicals and waste into water supplies, the leaking of greenhouse gases during … See more • Unconventional (oil & gas) reservoir • Biogas • Oil sands • Peak oil • Tight gas • Fracking See more WebHomepage - U.S. Energy Information Administration (EIA) the gilded age video
