Mobil Producing Nigeria has said the source of oil spill noticed on the Atlantic coastline in Ibeno, Akwa Ibom, is unknown.
Deposits suspected to be crude oil were reported on Monday by residents of Atia community in Ibeno, within the Qua Iboe oil field operated by MPN.
Mobil Producing, an affiliate of United States energy firm ExxonMobil, operates two offshore oil blocks and a 960, 000 barrels per day crude export terminal, off the Akwa Ibom coastline.
A statement by Mobil in Eket on Tuesday said that a response team had been deployed to the spill site and samples taken to ascertain its source.
Mobil Producing Nigeria Unlimited, operator of the Nigerian National Petroleum Corporation (NNPC)/MPN Joint Venture, confirms that oiling from an unknown source had been sighted on the shoreline, near Ibeno, Akwa Ibom.
"An emergency response team was immediately dispatched to the shoreline and samples of the substance collected for fingerprinting to determine its source, which remains unknown," it stated.
The statement signed by the General Manager, Public and Government Affairs, Mr. Paul Arinze, added that relevant government and regulatory agencies had been duly notified.
The MPN restated its commitment to high safety, health and environmental standards in its operations and well-being of its host communities.
