Two oil wells operated by Nigerian firm Eroton Exploration and Production Limited caught fire on Monday and were still burning on Tuesday after the company hired a contractor to try extinguish the fire, the agency responsible for detecting oil spills said.
It was not immediately clear if this was the same area where a well operated by Eroton spilled oil and gas into the Niger Delta for more than a week in June.
Eroton produces and exports crude from its Oil Mining Lease 18 block through the Nembe Creek Trunkline.
