Shale Gas Estimates Decline Sharply In EIA Report

March 2012, Vol. 239 No. 3

The Energy Information Administration (EIA) has released a report showing drastically lower estimates of natural gas resources in the U.S. The agency estimated there are 482 Tcf of shale gas in the U.S., a decrease of more than 40%. The report also estimated the Marcellus region of New York, Ohio, Pennsylvania and West Virginia contained only 141 Tcf of gas. This is a decrease of 66% from earlier estimates of 410 Tcf.

Previously, the Marcellus shale region was thought to contain enough gas to meet the demands of the entire nation for 17 years. Instead, the estimate is that at current consumption rates the region provides only a six-year supply.
