OPEC Monday reported an estimated cut in output of 890,000 barrels in January to 32.14 million barrels a day.
OPEC began implementing cuts of 1.2 million barrels per day at the beginning of this year for six months.
Non-OPEC members led by Russia have also agreed to reduce production by 558,000 barrels a day.
