(ICIS) -- The US holds domestic resources of natural gas of about 2.170.000bn cubic feet (bcf), a record level that is attributed largely to expanding shale gas reserves, the Potential Gas Committee (PGC) said on Wednesday.
The Potential Gas Committee, based at the Colorado School of Mines, said that its 2010 biennial report on the nation's gas resources showed a gain of more than 4% in recoverable gas since the committee's 2008 evaluation.
The committee report said that its new total for available gas supply is the highest in the PGC's 46-year history.
Shale gas resources account for 687.000 bcf of the total, or nearly one-third of US natural gas supplies, the report indicated.
