The Department of Energy later partnered with private gas companies to complete the first successful air-drilled multi-fracture horizontal well in shale in 1986. The federal government further incentivized drilling in shale via the Section 29 tax credit for unconventional gas from 1980–2000.
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.
Marcellus natural gas trend. 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 ...
Barnett Shale - stratigraphy. The Barnett Shale is a geological formation located in the Bend Arch-Fort Worth Basin. It consists of sedimentary rocks dating from the Mississippian period (354–323 million years ago) in Texas. The formation underlies the city of Fort Worth and underlies 5,000 mi 2 (13,000 km 2) and at least 17 counties.
The oil shale industry is an industry of mining and processing of oil shale —a fine-grained sedimentary rock, containing significant amounts of kerogen (a solid mixture of organic chemical compounds), from which liquid hydrocarbons can be manufactured. The industry has developed in Brazil, China, Estonia and to some extent in Germany and Russia.
The commercial-scale production of shale oil began in 1930 in Fushun, Manchuria, with the construction of the "Refinery No. 1" operating Fushun-type retorts. [70] In Russia, Kashpirskoye oil shale near Syzran in the Volga region was mined and processed in 1919–1924 and again starting from 1929. [19]
There were three major past attempts to establish an American oil shale industry: the 1850s; in the years during and after World War I; and in the 1970s and early 1980s. Each time, the oil shale industry failed because of competition from cheaper petroleum . As of 2014, there are a number of companies doing research and development on oil shale ...
Utica Shale drilling and production began in Ohio in 2011. Ohio as of 2013 is becoming a major natural gas and oil producer from the Utica Shale in the eastern part of the state. [10] Map of Ohio Utica Shale drilling permits and activity by date. [11] [12] In 2011 drilling and permits for drilling in the Utica Shale in Ohio reached record highs ...
