EFCC discovers illegal refinery in Ogun State
Anti-corruption operatives have uncovered an abandoned illegal oil processing facility allegedly run by foreign nationals in Ogun State.
Key points
- EFCC operatives raided the clandestine facility in Ogere on October 31.
- Investigators found underground tanks containing suspected automotive gas oil.
- Raw materials were reportedly transported from Delta and Rivers states.
What happened
According to reports from Punch and Head Topics, the Economic and Financial Crimes Commission (EFCC) raided a clandestine petroleum processing site in the Ogere district of Ogun State. The operation took place on Saturday, October 31, 2026, and was executed by the agency's Lagos Zonal Directorate 2 following intelligence-gathering efforts.
Dele Oyewale, the EFCC Head of Media and Publicity, stated that the location was empty when authorities arrived. The enforcement action followed prior regulatory checks targeting unauthorized mineral processing plants in the surrounding region. Inside the premises, officers discovered physical evidence of refining activities, including subterranean reservoirs utilized for thermal processing.
Operational methods
Preliminary findings indicate that the individuals running the site procured sludge oil from southern hubs situated in Warri, Delta State, and Port Harcourt, Rivers State. This viscous material was hauled northward to Ogun State to undergo intense thermal treatment and filtration.
The processing technique separated lighter petroleum fractions, ultimately yielding substances identified by authorities as Automotive Gas Oil, commonly known as diesel, intended for the domestic market. Facility workers reportedly maintained that the Chinese managers concealed their real names and corporate affiliations. Consequently, the EFCC has secured the location while inquiries into economic sabotage and facility ownership continue.
Why it matters
According to World Bank figures provided by CEII data, fuel exports accounted for 85.9 percent of Nigeria's merchandise exports in 2025, highlighting the fundamental importance of the hydrocarbons sector to the national economy. Incidents of illegal refining and feedstock diversion threaten the stability of domestic petroleum value chains and undermine regulatory oversight.
For energy investors and policy makers, safeguarding infrastructure from illicit processing operations is vital for maintaining market transparency. Unregulated production can disrupt local supply dynamics and affects refined product pricing environments, at a time when global diesel spot prices stood at 4.767 US dollars per gallon on the US Gulf Coast according to US EIA data from late October 2026.

Context from CEII
Crude benchmarks move budgets, currencies and inflation in producer and importer countries alike. For economies such as Nigeria, where fuels dominate exports, production and refining decisions move the whole economy.
