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 Marcellus is an example of shale gas, natural gas trapped in low-permeability shale, and requires the well completion method of hydraulic fracturing to allow the gas to flow to the well bore. The surge in drilling activity in the Marcellus Shale since 2008 has generated both economic benefits and environmental concerns—and thus ...
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]
Oil shale can be regarded as an organic-rich but immature source rock from which little or no oil has been generated and expelled. [2] Subsurface source rock mapping methodologies make it possible to identify likely zones of petroleum occurrence in sedimentary basins as well as shale gas plays.
Map showing the location of the oil and gas assessment units (AU) for the Utica Shale in the Appalachian Basin Province. 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 ...
Nov. 24—Starting with a model of the Texas economy when he was a young professor at Baylor University, economist Ray Perryman of Odessa built a global system that lets him analyze thousands of ...
The Antrim Shale is a formation of Upper Devonian age in the Michigan Basin, in the US state of Michigan, and extending into Ohio, Indiana and Wisconsin. It is a major source of natural gas in the northern part of the basin.
