The Economic and Financial Crimes Commission said it uncovered a suspected illegal oil refinery in Ogere, Ogun State, where two underground tanks contained substances believed to be Automotive Gas Oil, also known as diesel. The EFCC said the site was allegedly operated by Chinese nationals and was discovered on Saturday, October 31, 2026, after intelligence and surveillance by operatives from its Lagos Zonal Directorate 2.
The Economic and Financial Crimes Commission said it uncovered a suspected illegal oil refinery in Ogere, Ogun State, during an operation on Saturday, October 31, 2026.
According to the commission, the site was allegedly operated by Chinese nationals. EFCC operatives from Lagos Zonal Directorate 2 carried out the operation after intelligence gathering and surveillance on suspected sludge-oil refining activities.
The facility was deserted when operatives arrived. Investigators, however, said they found waste products from the refining process as well as underground processing tanks at the location.
The EFCC said two of the underground tanks inspected during the operation contained substances suspected to be Automotive Gas Oil, commonly known as diesel.
Preliminary findings by investigators indicated that black sludge used at the site was sourced from Warri in Delta State and Port Harcourt in Rivers State. The commission said the material was then transported to the Ogere facility for processing.
No arrests were stated in the verified details supplied. The EFCC also described its findings as preliminary, indicating that further investigation is expected.
Why it matters
The case points to suspected illegal refining activity outside the Niger Delta, with Ogun identified as the processing location while raw material was said to have come from Delta and Rivers states. It also shows how alleged petroleum-related crime can involve cross-state movement of materials and hidden infrastructure such as underground tanks.
What it means for your money
There is no direct personal-finance action for readers from the verified facts alone. However, the case concerns suspected diesel processing, a fuel widely used by businesses and households, so any confirmed enforcement outcome may be of wider public interest.

The key development to watch is the EFCC's next update on the investigation, including any laboratory confirmation of the substances found in the tanks and any arrests or charges. It will also be important to monitor whether authorities release more details on the supply chain described in the preliminary findings, especially the movement of black sludge from Delta and Rivers to Ogun.
EFCC says a suspected illegal refinery in Ogere, Ogun State, contained two underground tanks with substances believed to be diesel, with preliminary findings linking the site to sludge supplies from Warri and Port Harcourt. The agency's next disclosures will be important in confirming the scope of the case.
