Get Oil/Natural Gas Proved Reserve

Proven reserves sit at the top of the scale, at a 90-percent or above likelihood of commercial extraction. Probable reserves are those with the likelihood of recovery for between possible and proved reserves, or over 50-percent but under 90-percent.

At the rate of U.S. natural gas consumption in 2016 of about 27.5 Tcf per year, the United States has enough natural gas to last about 90 years. The actual number of years will depend on the amount of natural gas consumed each year, natural gas imports and exports, and additions to natural gas reserves.

Assuming the same annual rate of U.S. dry natural gas production in 2019 of nearly 34 Tcf, the United States has enough dry natural gas to last about 84 years. The actual number of years the TRR will last depends on the actual amount of dry natural gas produced and on changes in natural gas TRR in future years.

There are 303.2 billion barrels worth of oil in the country, nearly 18% of global reserves.

The world has proven reserves equivalent to 46.6 times its annual consumption levels. This means it has about 47 years of oil left (at current consumption levels and excluding unproven reserves).

At the current rates of production, oil will run out in 53 years, natural gas in 54, and coal in 110.

Proven reserves are the amount of oil or natural resources contained under a piece of land with a 90% or greater probability of profitable extraction.

EIA estimates that as of January 1, 2019, the United States had about 475 Tcf of proved reserves and 2,392 Tcf of unproved reserves of dry natural gas.

Proven reserves are those that claim an approximate certainty level of at least 90% of being successfully recovered. For specialists in the oil industry, proven reserves are known as P90 or 1P.

Natural gas - countries with the largest reserves 2009-2019. Russia has the largest proved natural gas reserves in the world. As of 2019, it had 38 trillion cubic meters worth of the fossil fuel, four trillion cubic meters more than ten years prior.
