EFCC uncovers suspected illegal oil refinery allegedly operated by Chinese nationals in Ogun State

The Economic and Financial Crimes Commission (EFCC) has uncovered a suspected illegal oil refinery in Ogere, Ogun State, allegedly linked to Chinese nationals.
The discovery has raised fresh concerns about illegal petroleum processing in Nigeria, especially the possibility that some operations are running quietly in places far from the country's major oil-producing areas.
The raid
According to reports, EFCC operatives raided the facility on Saturday, 31 October 2026, but nobody was found on the premises when they arrived.
During the operation, investigators discovered underground storage tanks holding substances suspected to be diesel, suggesting the site may have been used for petroleum processing and storage.
Sludge oil from Warri and Port Harcourt
Preliminary investigations reportedly showed that sludge oil was transported from Warri in Delta State and Port Harcourt in Rivers State to the Ogun State facility, where it was allegedly processed into petroleum products.
That detail raises an important question: how was petroleum waste moved across several states to a facility allegedly operating outside the law without attracting the attention of the relevant authorities?
Questions for investigators
Given the size and nature of such an operation, investigators will also need to establish how long the facility had been running, who financed it and whether other individuals or companies were involved.
The EFCC has reportedly taken control of the premises while investigations continue to identify those responsible, including the alleged owners and operators.
Although Chinese nationals have been linked to the facility, the identities of those involved have not been publicly established, and the allegations remain under investigation.
A wider problem
For many Nigerians, the discovery points to a familiar and troubling issue. While the country continues to battle crude oil theft, illegal refining and lost revenue in the petroleum sector, questions remain about how such operations are set up and kept running.
The authorities are now expected to determine the full extent of what went on at the Ogere facility and whether any laws were broken.
The big question
Who owns this refinery, how long has it been operating, and who has been supplying the materials used there?
As the EFCC investigation continues, Nigerians will be watching to see whether those behind the suspected operation are identified and brought before the law.
- The EFCC raided the Ogere facility on 31 October.
- No one was found on the premises.
