Proved reserves of natural gas increased 32% in the United States during 2021

Proved reserves of natural gas in the United States grew to a new record of 625.4 trillion cubic feet (Tcf) in 2021, a 32% increase from 2020, according to our recently released Proved Reserves of Crude Oil and Natural Gas in the United States, Year-End 2021 report. U.S. proved reserves had previously decreased 4% in 2020 as a response to prices that fell with decreased consumption during the first year of the COVID-19 pandemic. At year-end 2021, however, five of the eight states with the most proved reserves of natural gas each reported new record volumes, driving the growth nationally.
