Shell shuts down Nigeria field over oil spill

LAGOS, Nigeria — 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 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.
