Estimates of future potential natural gas supplies in the United States stood at a record 3,141 Tcf at the end of 2016, 64% of which is shale, according to a biennial report conducted by the Potential Gas Committee (PGC). Technically recoverable natural gas volumes rose 12% since the end of 2014 to a record 2,817 Tcf. Proven gas reserves were 324 Tcf. The U.S. Geological Survey (USGS) estimates that there are about 1,750 trillion cubic feet (tcf) of technically recoverable shale gas, with an average yield of 1.05 tcf.

Technically recoverable natural gas volumes rose 12% since the end of 2014 to a record 2,817 Tcf. Proven gas reserves were 324 Tcf. Traditional gas resources, including conventional, tight sand, carbonate and shale reservoirs, accounted for 2,658 Tcf of the technically recoverable volumes, while coalbed methane made up the remaining 159 Tcf.
