Libya’s oil output has been slashed to between 600,000 and 700,000 barrels per day (bpd) from more than one million following clashes at its Ras Lanuf and Es Sider oil terminals, a Libyan oil source said.

The National Oil Corporation (NOC) is looking at options to divert some oil exports from Ras Lanuf to Brega and Zueitina terminals, the source said.

Ras Lanuf and Es Sider have been closed since June 14, when armed factions opposed to Khalifa Haftar’s Libyan National Army (LNA) attacked the two ports, forcing the NOC to close them and declare force majeure on exports.

The attack has caused a drop in oil production of 450,000 bpd, NOC Chairman Mustafa Sanalla said.

He added that NOC subsidiary Arabian Gulf Oil Company (Agoco) had also lost an unspecified amount of production due to a technical problem. Agoco exports crude oil from Hariga terminal in Libya’s far east.
