U.S. Crude Oil, Natural Gas, and Natural Gas Liquids Reserves

Annual data on proved reserves of crude oil, natural gas, and natural gas liquids in the U.S. Based on EIA Form-23L data. Proved reserves are estimated volumes of hydrocarbon resources that analysis of geologic and engineering data demonstrates with reasonable certainty are recoverable under existing economic and operating conditions. Reserves estimates change from year to year as new discoveries are made, existing fields are more thoroughly appraised, existing reserves are produced, and prices and technologies change.
