EFCC uncovers Chinese-operated illegal oil refinery in Ogun State
Nigeria's EFCC uncovered an illegal oil refinery allegedly operated by Chinese nationals in Ogun State on October 31, 2026, discovering underground tanks with suspected diesel and evidence of sludge oil processing. The discovery followed an earlier crackdown on four illegal lithium processing plants in the same area, and authorities are investigating the identities of operators and full extent of the operation.

Nigeria's Economic and Financial Crimes Commission (EFCC) has uncovered an illegal oil refinery allegedly operated by Chinese nationals in Ogere, Ogun State, following a raid on October 31, 2026. Operatives from the Lagos Zonal Directorate 2 discovered the facility deserted, but found waste products and underground tanks suspected of being used for heating and processing sludge oil. Two of the inspected tanks contained substances believed to be Automotive Gas Oil (AGO), or diesel.
According to preliminary investigations, the operators sourced sludge oil—also called black sludge—from Warri in Delta State and Port Harcourt in Rivers State, then transported it to Ogere for processing. The refining process involved subjecting the sludge oil to intense heat, allowing lighter petroleum components to pass through a series of chambers and filters to produce diesel for sale in the Nigerian market. Security personnel at the facility told EFCC operatives that the Chinese operators never disclosed their identities or the name of the company operating the facility.
The discovery was announced on Tuesday, November 3, 2026, by EFCC Head of Media and Publicity Dele Oyewale. The operation followed earlier intelligence gathering and surveillance of illegal sludge oil refiners, and came after the EFCC's earlier crackdown on four illegal lithium processing plants in the same area. On October 23, 2026, the EFCC had arrested 15 people—14 Chinese nationals and one Nigerian—in connection with those lithium-processing operations.
Operatives have taken control of the premises as investigations continue to establish the identities of the alleged operators, the ownership of the facility, and the full extent of suspected illegal activities. The EFCC is investigating the operation as a suspected case of economic sabotage.
Why This Matters
The discovery of illegal oil refinery operations in Nigeria's Ogun State affects environmental compliance, fuel supply chains, and law enforcement priorities. EFCC operations indicate coordinated enforcement against unauthorized petroleum processing in West Africa's largest oil producer, where regulatory oversight of sludge oil sourcing and refining capacity has measurable impacts on licensed refinery operations, fuel pricing, and transnational criminal investigation scope. The simultaneous crackdown on lithium processing (14 Chinese nationals arrested October 23) signals expanded scrutiny of foreign-operated informal mineral and petroleum extraction networks.
