Suspected armed militants in gunboats attacked an oil flow station, operated by Royal Dutch Shell (RDSa.L), in the southern Niger Delta early on Monday, a military spokesman said.
Colonel Rabe Abubakar, spokesman for the military taskforce in the western Niger Delta, said the facility was attacked by gunmen in five speedboats at Nembe in Bayelsa state.
There was no damage to the oil flow station, which was being worked on by Lagos-based Nestoil Ltd, he said.
“The facilities remain intact, there were no casualties to our troops,” Abubakar said in a statement.
Shell officials were not immediately available for comment.
This was the second attack in the last four days on an oil facility in the Niger Delta, the heart of Nigeria’s oil and gas sector.
Chevron (CVX.N) confirmed on Monday an attack by suspected militants on its oil pipeline in Delta state on Friday, shutting down around 11,500 barrels per day of production.
Attacks on pipelines and industry installations are common in the Niger Delta. The unrest has shut down more than a fifth of Nigerian oil output over the past three years.
