The members of the OPEC+ group boosted their production in September by 630,000 barrels per day (bpd) from August as the alliance last month completed the unwinding of 2.2 million bpd cuts that began in April this year.
Total OPEC+ crude oil production averaged 43.05 million barrels per day (bpd) in September 2025, up by 630,000 bpd from August, estimates from OPEC’s secondary sources showed in the cartel’s Monthly Oil Market Report (MOMR) out on Monday.
OPEC-only production grew by 524,000 bpd to 28.44 million bpd, driven by a jump in the output of Saudi Arabia, the cartel’s biggest oil producer which is entitled to the biggest monthly increments in production, per the OPEC+ agreement.
The Kingdom raised its crude production to 9.961 million bpd in September, up by 248,000 bpd from August. The United Arab Emirates (UAE) boosted output by nearly 100,000 bpd as it won a higher quota due to growing production capacity.
More than 80,000 bpd of the OPEC output growth came from the three producers exempted from the OPEC+ pact – Iran, Libya, and Venezuela, according to OPEC’s secondary sources.
Among the non-OPEC producers, production increased by 106,000 bpd, almost exclusively due to higher output in Russia.
Russia raised its production by 148,000 bpd to 9.321 million bpd in September, the figures from OPEC’s secondary sources showed.
Last week, Russian Deputy Prime Minister Alexander Novak said that Russia had raised its oil production close to its ceiling in the OPEC+ deal.
Among the other non-OPEC producers in the OPEC+ deal, Kazakhstan lowered its production by 26,000 bpd last month, OPEC’s report showed.
However, at 1.84 million bpd production for September, Kazakhstan continues to vastly exceed its OPEC+ quota, which was 1.55 million bpd for last month.
Kazakhstan says it remains committed to the OPEC+ deal, despite constantly busting its quota as it raises production from expansion projects led by international majors, including Chevron.
