Nigeria, Africa’s largest oil producer and a member of the Organization of the Petroleum Exporting Countries (OPEC), earned an estimated N55.5 trillion from crude oil sales in 2025. The NUPRC reported total production of 530.41 million barrels of crude oil for the year. Okay News reports that production fluctuated throughout the year, opening strongly at 47.70 million barrels in January but dipping to lows of 41.02 million barrels in February and 41.69 million barrels in September. Output for December 2025 was 44.08 million barrels, or 1.422 million barrels per day (bpd), which was 95 per cent of the country’s OPEC quota for that month. Professor Segun Ajibola highlighted issues such as insecurity in the Niger Delta, pipeline vandalism, and alleged crude oil theft.
