EFCC says it has uncovered an illegal oil refinery in Ogun, allegedly run by Chinese nationals who fled before the raid

Nigeria's anti-graft agency, the EFCC, says it has uncovered an illegal oil refinery in the Ogere area of Ogun State, allegedly operated by Chinese nationals. Operatives of the commission's Lagos Zonal Directorate 2 moved on the facility on Saturday 31 October after intelligence gathering and surveillance; the site was deserted when they arrived, but they found refining waste and underground tanks, two of which held substances suspected to be diesel. The commission says preliminary findings show sludge oil was brought from Warri in Delta State and Port Harcourt in Rivers State and processed into diesel for sale in the Nigerian market. The alleged operators' identities and company are unknown — the commission says they never disclosed either — and its operatives have taken over the premises while investigations continue.

Key points

  • The EFCC says the Ogere facility, found on 31 October after surveillance, was deserted on arrival — with refining waste and underground tanks left behind, two holding suspected diesel.
  • Its preliminary account: black sludge trucked in from Warri and Port Harcourt, heated and filtered into diesel for sale in Nigeria.
  • The alleged Chinese operators are unnamed and their company unknown — that element is the commission's allegation, labelled Not yet verified; the EFCC has taken over the site and says investigations continue.

What happened

The discovery follows the commission's earlier operation in the same Ogere area: on 23 October its operatives arrested 15 suspects — 14 Chinese nationals and one Nigerian — over alleged illegal lithium-processing at four facilities, per the EFCC's account reported by Everyday.ng. Whether the people behind the lithium plants and the refinery are connected is not established — Everyday.ng notes there is no official confirmation of any link — and none is claimed here.

Illegal refining is one of Nigeria's most damaging economic crimes: stolen or waste oil 'cooked' in unlicensed plants feeds an informal diesel market, evades the taxes and standards of the legal trade, and pollutes the land and water around the sites. A plant allegedly run by foreign nationals who never gave a name, within reach of Lagos, is the organised end of that trade rather than the creek-side version of it.

Claim by claim

Verified
The Economic and Financial Crimes Commission (EFCC) says it uncovered a suspected illegal oil refinery in the Ogere area of Ogun State on Saturday 31 October 2026. The discovery was made by operatives of its Lagos Zonal Directorate 2 following credible intelligence and surveillance of illegal sludge-oil refiners in the area, and was announced in a statement issued on Tuesday 3 November by the commission's Head of Media and Publicity, Dele Oyewale. The refinery was deserted when operatives stormed the premises, following the commission's earlier clampdown on four illegal lithium-processing plants in the same area.

Why this label: The EFCC's own statement as reported by BusinessDay (read in full in this pass), with the statement's date and spokesman also in Daily Trust's report (queue #1470) and Everyday.ng's fuller account. That the commission made this announcement and carried out this operation is verified; what the site was used for is the commission's account, in the next claims.

On the ladder: a claim earns Verified from primary evidence, or from two independent sources that do not copy each other.

Verified
At the site, operatives found waste products from the refining process and underground tanks believed to have been used for heating and processing sludge oil; two of the tanks inspected contained substances suspected to be Automotive Gas Oil (AGO) — diesel. The commission's preliminary investigations say the operators sourced sludge oil, also known as black sludge, from Warri in Delta State and Port Harcourt in Rivers State, transported it to Ogere, and subjected it to intense heat, passing the lighter components through a series of chambers and filters in a process believed to produce diesel for sale in the Nigerian market.

Why this label: The findings are the EFCC's own preliminary account as reported by BusinessDay and, in the same terms, by Chronicle NG and QNC News. They are carried as the commission's findings — the substances are 'suspected' diesel in the commission's own wording, and no court has tested any of it, which the wording of this claim keeps visible.

On the ladder: a claim earns Verified from primary evidence, or from two independent sources that do not copy each other.

Not yet verified
Who actually ran the refinery is not established. The EFCC says the facility was allegedly operated by Chinese nationals, and that security personnel found at the premises told investigators those operators never disclosed their identities or the name of the company behind the facility. No arrests in connection with the refinery itself had been announced by the commission as of its Tuesday statement; its operatives have taken over the premises, and it says investigations continue to establish the operators' identities, the facility's ownership and the full extent of the suspected illegal activities and economic sabotage.

Why this label: The 'operated by Chinese nationals' element is the commission's allegation, resting on what site security personnel told investigators — no operator was found at the site and none is named. It is therefore labelled Not yet verified and attributed to the EFCC everywhere on this page, headline included; the absence of announced arrests is the position in the commission's statement as reported by BusinessDay, Everyday.ng and QNC News.

On the ladder: the evidence so far sits low — early, single or social sources. We publish the claim as a claim, never as fact.

What we know / what we don't know yet

What we know

  • What the EFCC says it found and did — the 31 October operation, the deserted site, the tanks and suspected diesel, the Warri/Port Harcourt sludge route in its preliminary findings, and its takeover of the premises — from its own statement as reported by BusinessDay, Daily Trust, Chronicle NG and QNC News in matching terms.

What we don't know yet

  • The identities of the alleged operators and the company behind the facility — the commission says they were never disclosed, and no refinery arrest had been announced by Tuesday.
  • How much sludge oil the plant processed, over how long, and where its diesel was sold — the commission says establishing the full extent of the operation is part of its continuing investigation.
  • Whether the refinery is connected to the four illegal lithium plants raided in the same area in October — no official confirmation of a link exists.

Why it matters

Nigeria loses revenue, lawful diesel sellers lose a market, and host communities absorb the pollution when sludge oil is cooked into fuel outside the law. This case matters because of its alleged shape: not a creek camp but a serviced industrial site, supplied from two oil cities, allegedly run by operators who kept their names and their company off every record the EFCC could find on site.

Background

  • EFCC operatives arrest 15 suspects — 14 Chinese nationals and one Nigerian — over alleged illegal lithium processing at four facilities in the Ogere area (EFCC account, via Everyday.ng).

  • EFCC Lagos Zonal Directorate 2 operatives move on the Ogere refinery site after intelligence and surveillance; it is deserted on arrival.

  • The EFCC announces the discovery in a statement by spokesman Dele Oyewale, says its operatives have taken over the premises, and says investigations continue.

    Story published in Checking state as a brief from queue #1470 (Daily Trust). The operation and findings are carried as the EFCC's own account from its Tuesday statement; the alleged operators' identities are labelled Not yet verified and attributed to the commission everywhere, headline included, because no operator was found at the site or named. The hero is a labelled file photo of refinery storage tanks, not of the Ogere facility.
