Frequently Asked Questions

How much natural gas does the United States have and how long will it last?

The U.S. Energy Information Administration estimates that as of January 1, 2012 there were about 2,266 trillion cubic feet (Tcf) of technically recoverable resources of dry natural gas in the United States.  At the rate of U.S. dry natural gas consumption in 2012 of about 26 Tcf per year, the United States has enough natural gas to last about 87 years. The actual number of years will depend on the amount of natural gas consumed each year, the amounts of natural gas imports and exports, and additions to natural gas reserves.

Technically recoverable reserves consist of proved reserves and unproved resources. Proved reserves of crude oil and natural gas are the estimated volumes expected to be produced, with reasonable certainty, under existing economic and operating conditions.  Unproved resources are additional volumes estimated to be technically recoverable without consideration of economics or operating conditions, based on the application of current technology.
