Crude oil production in Alaska averaged 448,000 barrels per day (b/d) in 2020, the lowest level of production since 1976. Last year’s production was over 75% less than the state’s peak production of more than 2 million b/d in 1988. Production declined in 28 of the 32 years since Alaska’s oil production peak as the state’s oil fields have matured. The 4% decrease in annual oil production in Alaska in 2020 was part of a larger decline in U.S. oil production.
