Libya’s oil production has fallen further to around 150,000 barrels per day (bpd), lower than last week’s official estimate of around 250,000 bpd, as protesters continue to cripple the sector, an National Oil Corp official said on Wednesday.

Crude oil exports have fallen to around 80,000 bpd, several traders close to the matter said, confined to the offshore Bouri and Al Jurf platforms which export four cargoes a month combined. Brega crude is now heading to the Zawiya refinery in the west.

Only three export terminals, Marsa Brega and the Jurf and Bouri platforms, remain open. There are two vessels waiting to load at the port of Hariqa in far eastern Libya which are having difficulty finding crude from shut oilfields, the official, who requested anonymity, told Reuters.

The energy committee of the General National Assembly, in touch with senior oil officials, said in a statement that production had almost “reached zero” due to the prolonged stoppages and was “causing huge losses to the Libyan state that would directly impact the livelihoods of ordinary Libyans.”

“Production has stopped as a result of the port closures and production has reached almost zero,” said Naji Mukhtar, the head of the GNA’s energy committee.

Mukhtar said the continued strike was hurting Libya’s international credibility and risked losing it long term customers.

Most gas fields in its eastern region, which had supplied power plants, have been shut in the worst disruption to Libya’s energy sector since the civil war in 2011.
