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). Resources in conventional, tight sand and carbonate reservoirs declined 10% (97 Tcf) from the last report, while shale resources climbed 29% (399 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. 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.
