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.
48 structural basins with shale gas and oil, in 39 countries, per the U.S. Energy Information Administration, 2011. As of 2013, the US, Canada, and China are the only countries producing shale gas in commercial quantities. The US and Canada are the only countries where shale gas is a significant part of the gas supply.
The Karoo Basin is large, extending across nearly two-thirds of the country, with the southern portion of the basin potentially favorable for shale gas. However, the basin contains significant areas of igneous sill intrusions that may impact the quality of the shale gas resources, limit the use of seismic imaging, and increase the risks of ...
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]
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]
"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. ...
