EFCC uncovers illegal refinery in Ogun allegedly run by foreign nationals

The Economic and Financial Crimes Commission (EFCC) says it has uncovered an illegal oil refinery in Ogere, Ogun State, allegedly run by Chinese nationals.
The raid
In a statement on Tuesday, 3 November 2026, the EFCC said operatives of its Lagos Zonal Directorate 2 raided the facility on Saturday, 31 October, after intelligence and surveillance of illegal sludge oil processing in the area. The site was empty when officers arrived, but there were signs of recent activity, including underground tanks containing a substance suspected to be diesel.
What investigators found
According to the commission, preliminary investigations showed that the operators sourced sludge oil from Delta and Rivers states and brought it to the Ogere site for processing. The EFCC said it has taken over the site and is investigating the operators, the owner of the property and possible economic sabotage. No arrests were announced.
Background
Illegal refining is a major problem in Nigeria, especially in the Niger Delta, where crude oil is stolen from pipelines and processed in makeshift refineries. The practice causes huge losses to the country, pollutes land and water, and has led to deadly fires. Security agencies say illegal refining has also spread to other parts of the country. The government has stepped up efforts against oil theft.
What happens next
The EFCC says investigations are continuing and suspects will be prosecuted if found.
- The site in Ogere was deserted but had tanks of suspected diesel.
- Operators allegedly sourced sludge oil from Delta and Rivers.
- The EFCC is investigating the operators and property owner.
