USGS Ups Estimate of Marcellus Gas

by Nicole Good on August 23, 2011

While New York awaits documents from three large energy companies in order to review the accuracy of their reserve estimates, the USGS released a new report today that significantly increases its previous estimate of how much natural gas is contained in the Marcellus Shale.  However, the estimate is still far below the 500 trillion cubic feet estimated by Penn State in 2008.

In 2002 the United States Geologic Survey estimated the Marcellus Shale to contain 1.2 trillion cubic feet of natural gas and 10 million barrels of natural gas liquids– not much when spread out over such a large area.  The USGS now estimates that number to be closer to 84 trillion cubic feet of technically recoverable natural gas and 3.4 billion barrels of technically recoverable natural gas liquids.
