The world's biggest crude oil producers ranked by annual production in millions of barrels, per the latest OPEC and EIA data.
Quick answer: 1. United States, 2. Saudi Arabia, 3. Russia, 4. Canada, 5. Iraq, 6. China, 7. United Arab Emirates, 8. Iran, 9. Brazil, 10. Kuwait.
This ranks the ten countries that produced the most crude oil and lease condensate in 2025, measured in millions of barrels annually. The top three — the United States, Saudi Arabia, and Russia — together account for well over 40% of global output, driven by the US shale boom, Saudi OPEC+ strategy, and Russia's export infrastructure. Figures are from OPEC's Annual Statistical Bulletin and the U.S. Energy Information Administration's International Energy Statistics, reflecting crude oil (including lease condensate) only — not natural gas liquids, refinery gains, or biofuels.
The world's largest oil producer for the seventh consecutive year, the US averaged over 13 million barrels per day in 2025, powered by the Permian Basin and other shale plays in Texas and New Mexico.
The world's largest crude exporter and OPEC's de facto leader, Saudi Arabia produced roughly 9 million barrels per day in 2025, adjusting output in coordination with the OPEC+ alliance.
The third-largest producer and the largest outside OPEC after the US, Russia sustained output near 9 million barrels per day despite Western sanctions, with fields in western Siberia driving production.
Canada ranks fourth as the Western Hemisphere's second-largest producer, with most output coming from Alberta's oil sands — a high-cost, capital-intensive source that is nonetheless among the world's largest reserves.
OPEC's second-largest producer, Iraq is heavily dependent on oil revenues (over 90% of government income). Production from the supergiant Rumaila and West Qurna fields anchors its output.
The world's largest oil importer is also a top producer, though its mature fields (especially Daqing) are in long-term decline. China's output is supplemented by advanced enhanced-oil-recovery techniques.
The UAE is OPEC's third-largest producer and one of the lowest-cost operators globally, with the giant Zakum field offshore Abu Dhabi accounting for a substantial share of national output.
Iran holds some of the world's largest proven reserves and is a major OPEC producer, though its output remains constrained by international sanctions and limited foreign investment in its energy infrastructure.
Brazil is South America's largest oil producer and a rapidly growing player, with deepwater pre-salt fields offshore the Santos Basin driving a steady production increase over the past decade.
Kuwait rounds out the top ten as a major OPEC producer with the Greater Burgan field — the world's second-largest oil field — as its primary source. Nearly all government revenue comes from oil.

Countries are ranked by total annual production of crude oil (including lease condensate) for 2025, expressed in millions of barrels. Primary sources are OPEC's Annual Statistical Bulletin 2025 (for OPEC members) and the U.S. Energy Information Administration's International Energy Statistics (for non-OPEC producers). Where OPEC and EIA figures diverge, the midpoint is used and noted. Share-of-world percentages are based on the ~35.8 billion barrels of global crude oil production in 2025 (EIA estimate). Production figures include crude oil and lease condensate but exclude natural gas plant liquids, other liquids, and refinery processing gain.
This list counts crude oil (including lease condensate — light liquid hydrocarbons recovered from natural gas at the wellhead) but excludes natural gas plant liquids, biofuels, refinery gains, and other liquids. This is the standard industry definition used by OPEC and the EIA for production comparisons.
The data are for calendar year 2025. Primary sources are OPEC's Annual Statistical Bulletin 2025 (for OPEC members) and the U.S. Energy Information Administration's International Energy Statistics (for non-OPEC producers). Where the two diverge for a given country, the midpoint estimate is used.
Saudi Arabia adjusts its crude output in coordination with the OPEC+ alliance, which has periodically imposed production quotas to manage global oil prices. Monthly and annual figures can vary significantly depending on the quota regime in effect.
The top ten producers collectively account for approximately 60% of world crude oil production. Of the remaining ~40%, notable producers just outside the top ten include Kazakhstan, Mexico, Norway, Nigeria, Libya, Oman, Qatar, and Algeria.
