U.S. GEOLOGICAL SURVEY UPDATE CHARTS 84 TCF GAS POTENTIAL IN APPALACHIAN BASIN; NUMBER DOES NOT ADD UP TO PRIOR ESTIMATES

摘要

An update issued by the U.S. Geological Survey (USGS) this week reported an estimated mean undiscovered natural gas resource base of 84,198 Bcf and a mean undiscovered natural gas liquids resource of 3,379 million barrels (MMb) in the Devonian Marcellus Shale within the Appalachian Basin Province. "All this resource occurs in continuous accumulations," the USGS said. The 2011 assessment of the undiscovered oil and gas potential of Marcellus Shale within the Basin covers parts of Alabama, Georgia, Kentucky, Maryland, New York, Ohio, Pennsylvania, Tennessee, Virginia, and West Virginia. The Appalachian Basin happens to be the oldest producing petroleum province in the U.S.
