Bloomberg reported that Libya took a major step toward reviving its battered oil industry by reopening its biggest field, presenting a new headache for OPEC+ as the alliance of major producers tries to curb global supplies.

The National Oil Corporation, Libya’s state energy company, lifted force majeure on the western deposit of Sharara and instructed its operator to resume production, according to a statement on Sunday. The field will initially pump 40,000 barrels of crude a day, before reaching its capacity of almost 300,000 barrels next week, a person with knowledge of the situation said.

“That would double overall output in Libya to around 600,000 barrels daily, said the person, who asked not to be identified because they aren’t authorized to speak to media.” Bloomberg stated.
