The OPEC Plus alliance said it had given Russia a higher base level for oil production after agreeing to review its production figures by research institutions, and the alliance set Russia's base level at 9.949 million barrels per day in February, compared to a previous level of 9.828 million barrels per day.

OPEC limits production cuts based on a baseline level, and raising that level means Russia can increase production under agreed quotas, more than planned, by 120,6 barrels per day, or <> million tonnes per year, enough to feed a small oil refinery.

Earlier this month, OPEC agreed to extend the current production cut until next year.

The OPEC statement noted that Russian production reached 9.533 million in May 2023, about 0.416 million less than February 2023 and slightly below the voluntary cut of 0.5 million pledged by the country in April 2023.

Russia has stopped reporting its oil production figures since the West imposed sanctions over its war on Ukraine.
