Nigeria and Angola each boosted output marginally in November but both are pumping far below their quotas, the survey found.
Nigeria reportedly posted OPEC’s largest increase, helped by higher exports of Forcados crude.
The Organisation pumped 29.01 million barrels per day (bpd), during the month in review the survey found, down 710,000 bpd from October. In September, OPEC output had been the highest since 2020.
