OPEC Production FAQ
How much oil does OPEC produce?
OPEC's 11 member countries produced 26.21 million barrels per day of crude oil (including lease condensate) in 2025, according to EIA International Energy Statistics. That is an annual average — output varies month to month with quotas, outages and demand.
Which OPEC country produces the most oil?
Saudi Arabia, at 9.55 million barrels per day in 2025 — about 36.4% of total OPEC crude output. Iraq is second at 4.39 Mb/d and Iran third at 4.05 Mb/d.
Is Russia a member of OPEC?
No. Russia is part of OPEC+, a wider group in which the 11 OPEC members coordinate output with a further set of non-OPEC producers including Russia, Kazakhstan and Mexico. Russia is not counted in the totals on this page, which cover OPEC members only. For Russian output see our Russia oil profile.
Is the UAE still an OPEC member?
No. The UAE left both OPEC and OPEC+ effective May 1, 2026, after a long-running dispute over its production quota — it had sought a higher ceiling to match capacity built up through a large domestic investment program. It was OPEC's third-largest producer at the time, behind only Saudi Arabia and Iraq, making it the largest member ever to leave. See our UAE oil profile for its production outside OPEC.
Why is this data annual rather than monthly?
The EIA International Energy Statistics series used here is published as annual averages, so the most recent complete year is the newest figure available. There is no free, structured, per-country monthly OPEC series; OPEC's own Monthly Oil Market Report (MOMR) carries monthly numbers but is not published as an open data feed. This page states the year on every figure rather than implying the numbers are current-month.
Do these figures show OPEC production quotas or actual output?
Actual measured output, not targets. OPEC members agree required production levels at ministerial meetings, but actual production regularly runs above or below quota — through overproduction, compensation cuts, or involuntary shortfalls from sanctions, conflict and field decline. Venezuela, Iran and Libya in particular produce well below their historical capacity for reasons unrelated to quotas.
Why do these numbers differ from OPEC's own published figures?
Definitions differ. This page uses the EIA's "crude oil including lease condensate" measure. OPEC's MOMR reports crude oil production from secondary sources, and other publishers include natural gas liquids (NGLs) or condensate differently. Differences of a few hundred thousand barrels per day between sources are normal and usually definitional rather than a disagreement about the facts.
Which countries have left OPEC?
Membership has changed repeatedly. The UAE left in May 2026, Angola in January 2024, Qatar in January 2019, and Indonesia suspended its membership in 2016; Ecuador withdrew in January 2020. The 11 countries listed on this page are the current members covered by the EIA series.
