U.S. proved reserves of crude oil increased significantly in 2021

In 2021, U.S. proved reserves of crude oil and lease condensate increased 16% from 2020, totaling 44.4 billion barrels, according to our recently released Proved Reserves of Crude Oil and Natural Gas in the United States, Year-End 2021 report. Proved reserves decreased 19% in 2020 because of pandemic-related constraints on crude oil demand and production. In 2021, however, demand for petroleum and natural gas returned, prices rose, and proved reserves increased.
