Russia’s crude oil production has fallen to its lowest level in a year, as Ukraine’s drone campaign against the country’s energy infrastructure puts one of Moscow’s key sources of revenue under growing strain.
Russian producers pumped an average of 9.009 million barrels of crude per day in May, down from April levels, the Organization of the Petroleum Exporting Countries (OPEC) said in its monthly report published on Thursday.

OPEC is a group of major oil-producing countries whose monthly reports are closely watched by energy markets. It works with Russia and other countries to set joint production targets under the wider OPEC+ framework.
The May figure was 690,000 barrels per day below Russia’s production target under the OPEC+ agreement, Bloomberg reported, citing an analysis of OPEC’s monthly report.
Oil revenues under pressure
Russia’s output has now fallen for six consecutive months, dropping by roughly 370,000 barrels per day since reaching a recent peak of 9.38 million barrels per day in November 2025.
The steady decline coincides with Ukraine escalating its attacks on Russian energy infrastructure, striking refineries, oil export terminals and pipelines.
Ukrainian forces carried out at least 31 strikes on Russian oil facilities in May, the highest monthly total since the start of Moscow’s full-scale invasion in 2022, according to Bloomberg.
