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 name derives from the Greenbrier River in West Virginia. Greenbrier Limestone is in some places more than 400 feet (120 metres) thick, allowing it to trap large quantities of oil and gas. Since this carbonate rock erodes quickly in the region's wet climate, outcrops are not prominent and are often quarried.
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.

A 2008 estimate set the total world resources of oil shale at 689 gigatones—equivalent to yield of 4.8 trillion barrels (760 billion cubic metres) of shale oil, with the largest reserves in the United States, which is thought to have 3.7 trillion barrels (590 billion cubic metres), though only a part of it is recoverable.

With 4% annual production growth expected between 2010 and 2030, shale gas has been "a veritable game changer" for the United States. [24] Shale gas, especially from the Marcellus Shale, have tested up to 16% ethane content. [25] This low priced feedstock for ethylene synthesis has led to a "frenzy" of new ethylene plants in the US. [26]
The Bureau of Mines built a test facility at Anvil Points on Naval Oil Shale Reserve 1, to test methods of mining, crushing, and retorting the Green River oil shales. It started to develop the gas combustion retort process. [14] In 1943 Mobil Oil built a pilot shale oil extraction plant and in 1944 Union built an experimental oil shale retort ...
It acts as a reservoir for a massive number of hydrocarbons, and a good supply of that gas comes from the rocks, particularly in Kentucky, Tennessee, and West Virginia. The Chattanooga Shale’s oil reserves were appraised by USGS, which took notes on large amounts of technically recoverable gas, oil, and NGLs in most appraisals over the years ...
