In contrast to older shale gas plays, such as the Antrim Shale, the New Albany Shale, and the Ohio Shale, the Barnett Shale completions are much deeper (up to 8,000 feet). The thickness of the Barnett varies from 100 to 1,000 feet (300 m), but most economic wells are located where the shale is between 300 and 600 feet (180 m) thick.
Shale gas is an unconventional natural gas that is found ... Accurately located earthquakes were along a subsurface fault trending ENE-WSW—consistent with the focal ...
In 1996, shale gas wells in the United States produced 0.3 × 10 ^ 12 cu ft (8.5 km 3), 1.6% of US gas production; by 2006, production had more than tripled to 1.1 × 10 ^ 12 cu ft (31 km 3) per year, 5.9% of US gas production. By 2005, there were 14,990 shale gas wells in the US. [20] A record 4,185 shale gas wells were completed in the US in ...
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]
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 ...
A map of 48 shale basins in 38 countries, based on US Energy Information Administration data, 2011.. This is a list of countries by recoverable shale gas based on data collected by the Energy Information Administration agency of the United States Department of Energy. [1]
Shale gas and associated liquids produced throughout the country can support all the major chemical-producing regions, including the U.S. Gulf Coast, which today serves as a major hub of ...
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. ...
