Shale gas is one of a number of unconventional sources of natural gas; others include coalbed methane, tight sandstones, and methane hydrates. Shale gas areas are often known as resource plays [27] (as opposed to exploration plays). The geological risk of not finding gas is low in resource plays, but the potential profits per successful well ...
US shale gas basins, 2011. Shale gas in the United States is an available source of unconventional natural gas.Led by new applications of hydraulic fracturing technology and horizontal drilling, development of new sources of shale gas has offset declines in production from conventional gas reservoirs, and has led to major increases in reserves of U.S. natural gas.
The Haynesville Shale is overlain by sandstone of the Cotton Valley Group and underlain by limestone of the Smackover Formation. [3] [4] It contains vast quantities of recoverable natural gas. This natural gas is known as "shale gas" because the wells produce from low permeability mudstones that are also the source for the natural gas. It was ...
Cases of long distance oil migration into shallow traps away from the "generative depressions" are usually found in foreland basins. Besides pointing to zones of high petroleum potential within a sedimentary basin, subsurface mapping of a source rock's degree of thermal maturity is also the basic tool to identify and broadly delineate shale gas ...
The Marcellus natural gas trend is a large geographic area of prolific shale gas extraction from the Marcellus Shale or Marcellus Formation, of Devonian age, in the eastern United States. [2] The shale play encompasses 104,000 square miles and stretches across Pennsylvania and West Virginia, and into eastern Ohio and western New York. [3]
A research paper by USGS geochemist Leigh Price in 1999 estimated the total amount of oil contained in the Bakken shale ranged from 271 to 503 billion barrels (43.1 to 80.0 billion cubic metres), with a mean of 413 billion barrels (65.7 billion cubic metres). [28]
"It's presently around 1,300 b/pd and the U.S. is now the world's leading oil and gas producer with about two-thirds of the incremental output occurring in the Permian Basin.
Gas wells producing from the Barnett Shale of the Fort Worth basin are designated as the Newark, East Gas Field by the Texas Railroad Commission. From 2002 to 2010 the Barnett was the most productive source of shale gas in the US; it is now third, behind the Marcellus Formation and the Haynesville Shale. In January 2013, the Barnett produced 4. ...
