LAGOS, Nigeria (AP) — Royal Dutch Shell PLC says it has shut down a deep-water oil field that was leaking oil into the sea off Nigeria's oil-rich southern delta.
Shell's Nigerian subsidiary said Wednesday it closed its Bonga field Tuesday after a leak that occurred while transferring crude oil to a tanker.
The company apologized and said it believes less than 40,000 barrels of oil leaked. It says it is cleaning up the spill.
A U.N. report released in August said it will take as much as 30 years to clean parts of Nigeria's oil-stained Niger Delta.
The company's website says Bonga, located 75 miles (120 kilometers) off the region's coast, has the capacity to produce more than 200,000 barrels a day of crude oil and 150 million cubic feet of gas a day.
Nigeria is a top supplier of crude to the U.S.
