Russian oil and gas condensate production fell to 39.7 million tonnes (9.39 million barrels per day) in May under a deal within the OPEC+ group.
The figure is down from 11.35 million barrels per day (bpd) in April.
Under the agreement between Russia and the Organisation of the Petroleum Exporting Countries (OPEC+), Moscow has pledged to reduce its output by around 2.5 million bpd to 8.5 million bpd to help support oil prices. The deal does not include output of gas condensate, a light oil.
Russia usually produces 700,000-800,000 bpd of gas condensate, meaning that excluding gas condensate, Russia produced 8.59-8.69 mln bpd of crude oil in May.
Russian oil exports outside the former Soviet Union in May are also said to have reached 17.36 million tonnes, or 4.1 million bpd, down 14.2 per cent year-on-year.
OPEC+ agreed to cut its combined output by around 10 million bpd, or 10 per cent of global oil production, in May and June, with a subsequent easing of the reductions, to combat economic fallout from the global pandemic.
OPEC+ may hold an online conference on June 4 to discuss its policy. The group is due to discuss extension of the output cuts in its current pace.
