Annual average U.S. crude oil production reached 9.3 million barrels per day (b/d) in 2017, an increase of 464,000 b/d from 2016 levels after declining by 551,000 b/d in 2016. In November 2017, monthly U.S. crude oil production reached 10.07 million b/d, the highest monthly level of crude oil production in U.S. history. U.S. crude oil production has increased significantly over the past 10 years, driven mainly by production from tight rock formations using horizontal drilling and hydraulic fracturing. EIA projects that U.S. crude oil production will continue to grow in 2018 and 2019, averaging 10.7 million b/d and 11.3 million b/d, respectively.
Although much has changed since 1970, Texas continues to produce more crude oil than any other state or region of the U.S. Texas has held the top position in nearly every year since 1970, with the exceptions of 1988, when Alaska produced more crude oil than Texas, and from 1999 through 2011, when production from the Federal Gulf of Mexico was higher.
