Libya's National Oil Corporation (NOC) has said it is losing 850,000 barrels per day of crude production due to a ports blockade by the Libyan National Army (LNA).
The situation has caused it to declare force majeure on loadings at Hariga, Zuetina, Es Sider and Ras Lanuf.
"Despite warning from NOC of the consequences of ongoing blockades, Libyan National Army (LNA) general command has declined to rescind its order that no vessel be allowed to port to receive allocated shipments," it said.
NOC chairman Mustafa Sanalla added: “Despite our warning of the consequences and attempts to reason with the LNA general command, two legitimate allocations were blocked from loading at Hariga and Zuetina this weekend. The storage tanks are full and production will now go offline.”
The financial loss to the public purse since an attack on Es Sider and Ras Lanuf on 14 June by militia leader Ibrahim Jadhran and his forces is more than $650m, NOC said.
Zuetina is a significant operational hub for the production of gas, condensate and LPG.
The action at the four terminals has resulted in the loss of 710m cbf of gas per day and more than 20,000 bpd of condensate.
"The power generation at the Zuetina and North Benghazi power stations will be badly affected," NOC said.
"The corporation is already facing a deficit in the fuel import budget and will not be able to compensate the lost gas due to the shutdown by importing more liquid fuel from abroad."
Daily revenue losses have been put at $67.4m.
Two oil storage tanks were destroyed in the attack at Ras Lanuf.
NOC has called on the LNA to end the blockade in the divided country.
Shut downs could follow
It had earlier said that in the event of force majeure being declared, Sirte Oil Company (SOC) would lose 60,000 bpd worth $4.4m per day at Brega due to limited storage capacity.
"At the point of stored oil being depleted, Brega refinery would be forced to close," it added.
SOC would also cease gas production.
Mellitah Oil & Gas Company would halt crude oil production from the Bu Attifel and Rimal fields, losing 72,000 bpd, plus 110m cbf of gas.
Zuetina Oil Company, Waha Oil Company and Agoco will also shutdown production and refineries.
And Wintershall will close down its fields, resulting in oil production losses of 60,000 bpd.
