German oil and gas producer Wintershall says it is producing oil again from eight fields in the Libyan desert.
The civil strife in the country forced a shutdown in February but the wells are now running at 20,000 barrels per day under an agreement with the Libyan National Oil Corporate.
The wells are in the desert 1,000 kilometers (600 miles) southeast of the capital, Tripoli.
Wintershall, part of BASF SE, said the facilities were undamaged and that Libyan employees of the company had looked after the sites during the fighting.
Production from the offshore platform Al Jurf in the Mediterranean, where Wintershall has a 6.75 percent stake, began several weeks ago.
