Royal Dutch Shell Plc.'s Nigerian subsidiary says it has resumed operation in a 200,000 barrel-per-day oil field in Africa's top oil producer.
Shell's Nigeria-based spokesman told The Associated Press Thursday that it would "ramp up production over the coming weeks" in its Bonga deep-water oil field.
The Bonga oilfield reopened Wednesday after having been shut down for two months for routine maintenance work.
The company's website says Bonga has the capacity to produce more than 200,000 barrels a day of crude oil and 150 million cubic feet of gas a day. Bonga, however, had not been producing to full capacity before its February shutdown.
Nigeria is a top supplier of crude to the U.S.
