U.S. Natural Gas Supply Facts (Energy Analysis 04/27/2011) 

U.S. Dry Natural Gas Reserves (2009)                                               273 Trillion Cubic Feet

·       Domestic gas reserves have grown from 169 Tcf to 273 Tcf (+62 percent) during the past 20 years.

·       Shale gas represents 61 Tcf (22 percent) of total U.S. dry natural gas reserves.

·       At current rates of production (about 21.6 Tcf annually), U.S. dry gas reserves represent a 13-year on-the-shelf inventory for consumers. This reserves life is up from 9-years in 1990.


U.S. Dry Natural Gas Production (2010)                                                            21.6 Trillion Cubic Feet

·       U.S. dry gas production has increased from 17.8 Tcf annually to 21.6 Tcf annually during the past 20 years (+21 percent).

·       Shale gas now accounts for one-quarter of all U.S. production.

·       Thirty-two states are now producing or have produced natural gas.

·       Domestic gas production now accounts for about 89 percent of all natural gas consumed in the United States, with the balance originating as pipeline imports from Canada and internationally traded liquefied natural gas (LNG).


Future U.S. Gas Supply (2010)                                                                          2,170 Trillion Cubic Feet 

·       The future supply of natural gas according to the Potential Gas Committee has grown 71 percent since 2000, due primarily to advances in gas extraction technology.

·       The Energy Information Administration also now estimates a national natural gas resource base over 2,000 Trillion cubic Feet (2,620 Tcf). Both PGC and EIA attribute about one-third of the domestic resource base to shale gas.

·       These natural gas future supply estimates point to a resource base capable of supplying natural gas markets for 100 years or more.
