Nigeria’s crude oil output fell to 1.39 million barrels per day (mbpd) in September 2025, extending a second consecutive month of decline and marking its lowest level in seven months.

According to the latest Monthly Oil Market Report released by the Organisation of the Petroleum Exporting Countries (OPEC), the figure dropped from 1.434 mbpd in August, remaining below Nigeria’s OPEC production target of 1.5 mbpd. OPEC said the data was sourced directly from Nigerian authorities.

The Nigerian Upstream Petroleum Regulatory Commission (NUPRC) attributed the shortfall to a three-day industrial strike by the Petroleum and Natural Gas Senior Staff Association of Nigeria (PENGASSAN), which disrupted several production and export facilities.

NUPRC’s breakdown showed that Nigeria’s combined crude and condensate production averaged 1.581 mbpd in September — with crude contributing 1.39 mbpd and condensates adding 191,373 barrels daily.

The strike, which arose from a disagreement between PENGASSAN and the Dangote Refinery, affected the country’s production schedule and export timelines.

Earlier in the year, Nigeria briefly exceeded its OPEC quota in January, June, and July, but recent labour disruptions have reversed that progress. Authorities are now working to stabilise production and restore normal output levels in the coming months.
