OPEC production rose last month after a recovery in crisis-torn Libya and a symbolic increase pledged by other members.
The Organization of Petroleum Exporting Countries boosted oil supplies by 230,000 barrels a day to 29.89 million, with about half the gain coming from the North African country, according to a Bloomberg survey.
Libya has seen a rebound in output after the government reached a July agreement with protesters and tribal leaders to reopen fields and export terminals largely shut for months.
Bloomberg’s survey is based on ship-tracking data, information from officials and estimates from consultants including Kpler Ltd. and Rapidan Energy Group.
