The Nigerian Upstream Petroleum Regulatory Commission has attributed the country’s dip in crude oil output to an unscheduled one-day maintenance shutdown at an oil facility.

NUPRC’s Head of Media and Strategic Communications, Eniola Akinkuotu, said in a statement on Saturday that the disruption caused production to slip below Nigeria’s Organisation of Petroleum Exporting Countries quota of 1.5 million barrels per day.

Data showed that Nigeria pumped an average of 1.43 mbpd in August, down from 1.507 mbpd in July and 1.505 mbpd in June.

The August figure represents a shortfall of about 66,000 barrels per day, after the country had exceeded its OPEC target for two consecutive months.

“On a month-on-month basis, there was a slight 4.7 per cent drop in combined crude oil and condensate production from 1.71 million bopd in July. Similarly, crude oil production itself declined by 4.8 per cent, down from 1.5 million bopd in July 2025.

“The month-on-month drop was driven by a single day of unscheduled maintenance at an oil facility,” the NUPRC stated.

According to NUPRC, combined crude and condensate output in August ranged between a low of 1.59 mbpd and a peak of 1.85 mbpd.

The Forcados Terminal led production for the month with a total of 8.99 million barrels, comprising 8.08 million barrels of crude oil and 915,200 barrels of condensates. It was followed by the Bonny Terminal, which recorded 6.26 million barrels in total—5.8 million barrels of crude and 418,270 barrels of condensates.

“Meanwhile, Qua Iboe Terminal recorded a total of 4.99 million barrels, with 4.94 million barrels of crude and 50.5k barrels of condensates. Escravos Oil Terminal also made a solid contribution, producing 4.18 million barrels, comprised of 4.08 million barrels of crude oil and 107,000 barrels of condensate,” it stated.

NUPRC further noted that average crude oil and condensate output rose to 1.63 mbpd in August 2025, compared with 1.58 mbpd in the corresponding period of 2024.
