The spill occurred on a pipeline running to a flow station, which, according to the company, had been shut-in.
The company said oil which spilled from the line has been contained and there has been no environmental damage. It did not, however, give an estimate of the amount of oil spilled.
“A leak was observed on a line from Well-39s flowing to Nembe Creek-2 flow station on 29th August,” Shell said in an emailed statement.
“The line was shut in, and booms were quickly deployed to stop spread of any spilled oil.
“A joint investigation visit took place on 31 August to determine the cause of the leak.”
The cause of the spill is unknown. However, Shell has frequently blamed such spills on sabotage as militant groups attempt to disrupt the country’s oil industry and criminals conduct illegal bunkering operations.
