This is a list of countries by oil production, as compiled from the U.S. Energy Information Administration database for calendar year 2016, tabulating all countries on a comparable best-estimate basis. Compared with shorter-term data, the full-year figures are less prone to distortion from periodic maintenance shutdowns and other seasonal cycles. The volumes in the table represent crude oil and lease condensate, the hydrocarbon liquids collected at or near the wellhead. The volumes in the table do not include biofuel. They also do not include the increase in liquid volumes during oil refining ("refinery gain"), or liquids separated from natural gas in gas processing plants ( natural gas liquids). 
Under this definition, total world oil production in 2016 averaged 80,622,000 barrels per day. Approximately 68% came from the top ten countries, and an overlapping 44% came from the fourteen current OPEC members, highlighted with blue shading in the table below.
The top three producers have in recent history been (alphabetically) Russia, Saudi Arabia, and the United States. Each of these countries experienced major production declines at different times in the past, but since 2014 all three have been producing near their peak rates of 9 to 11 million barrels per day.  Saudi Arabia and Russia also top the list of oil exporting countries, while Russia is not a member of OPEC. The monthly U.S. oil production reached 10.07 million b/d in November 2017, the highest monthly level of crude oil production in U.S. history.  In early 2018, the U.S. government forecast the country will become a net oil and gas exporter by 2022, the first time since 1953.
