A Libyan armed force controlling some of the country's southern oil fields has stopped pumping at two of them because the government has not paid the funds needed to maintain security operations, a brigade commander said on Aug. 30.

The closures underscore the new Libyan government's complex task in reviving oil production, which has been battered by strikes, protests and Islamist militant attacks since the fall of Muammar Gaddafi in the 2011 uprising.

Commander Mohammad Ahmad Alkhbasha told Reuters the Petroleum Facilities Guards' southern brigade had shut the Gulf Field and the Al Wafa Field, which usually produces about 30,000 barrels per day (bbl/d) of light oil condensate.

Al Wafa also produces gas supplies for Mellitah Port, jointly run with Italian oil company Eni for export to Italy.

"There are about six oil fields under our guards' control and we have stopped the pumping of crude oil from Gulf and Alwafa oil fields," the commander said. "But gas will be continued from Al Wafa normally."

A spokesman for the state-run National Oil Corp. was not immediately available to confirm the closures.

The southern oil guard brigade controls Al Wafa, Gulf, Al-Khamsa, El-feel, El-Sharara, and Senawang oil fields, and several wells and pipelines. El Feel and El Sharara had already been closed.

NOC chairman Mustafa Sanalla said on Aug. 30 that delays in the budget from Libya's new government for the state energy company were undermining oil production, losing about 200 Mbbl/d at the cost of millions of dollars.

Libya's oil production is below 300 Mbbl/d compared with the 1.6 MMbb/d peak before the fall of Gaddafi. Oil fields and ports have fallen under the control of rival armed factions allied with two competing governments that emerged in 2014.

In March this year, a U.N.-backed unity government in Tripoli, Libya, has tried to bring the factional fighting to an end, restart oil production and revive the economy. But it faces resistance from hardliners who reject its authority.

The Petroleum Facilities Guards last month agreed to a deal to reopen two major ports under their control, an agreement the NOC said would allow it to add 150 Mbbl/d in production. But the ports remain closed.
