Nigerian oil workers ended a strike that cut the country’s oil output over the last several days. The head of the union at an Exxon Mobil Corp. unit said members would return to work after negotiators reached an agreement with management about pensions.
Exxon Mobil said in a statement that it was restarting production.
Nigeria produces about 2.1 million barrels of crude a day. It is not clear how much effect the strike had on output.
Royal Dutch Shell PLC’s local unit also has shortfalls after militants blew up transport pipelines. Shell has said it may not be able to meet supply contracts totaling 169,000 barrels per day through May.
Nigeria is Africa’s biggest producer and supplies about a million barrels of crude a day to the U.S., according to the Energy Department.
