As you may know, Potential Gas Committee (PGC) recently released its biennial assessment of the nation’s natural gas resources. This from the report:

    • As a result of a substantial increase in the assessment of Appalachian basin shale gas, the PGC now ranks the Atlantic area as the country’s richest resource area with 33% of total U.S. … Changes in the total assessment from 2010 to 2012 arose primarily from analyses of recent drilling, well-test and production data from these three regions. The largest volumetric and percentage gains were reported for Appalachian basin shales (primarily the Marcellus but including other Devonian shales and the Utica), which collectively rose by 335 Tcf (147%).
