Libya's National Oil Corporation said on Tuesday it may declare force majeure on crude deliveries after members of the Petroleum Facilities Guard closed a valve on the main Hamada-Zawiya pipeline, bringing production and operations to a complete halt at the Hamada (NC8) field, the Tahara (NC4) field and the NC5 station. In a statement reported by The Libya Observer and OilPrice.com, the state oil company said the illegal closure caused a sudden jump in pressure at the Tahara field connection on the production lines.
The disruption is not necessarily contained. The Petroleum Facilities Guard said it would impose partial production cuts for one week at three additional fields — Wafa, Al-Khamsa and El Feel — and threatened a full shutdown if its demands are not met. The guard wants to be moved financially and administratively from Libya's defence ministry to the National Oil Corporation and has asked for a timetable to complete the transfer. The company said it could declare force majeure if the valve stays closed or if similar forced shutdowns hit other fields and wells, including North Hamada, which is operated by Nafusa Oil Operations.
Why a single valve matters
The standoff lands on top of the strongest Libyan output in more than a decade. OilPrice.com reported that production has climbed to roughly 1.4 million barrels per day, and that NOC is targeting 1.6 million barrels per day by the end of 2026 and 2 million barrels per day by the early 2030s. Reaching those levels could require $36 billion to $40 billion in foreign investment, according to NOC chairman Masoud Suleman.
The commercial framework has been rebuilt around that target. Libya signed exploration and production-sharing agreements this year with Repsol, Turkish Petroleum, Eni, QatarEnergy and MOL, following its first major licensing round in 17 years, while BP, Shell, Exxon and Chevron have also been pursuing a return. NOC received a $2 billion allocation under Libya's 2026 budget to support the programme. Every one of those commitments assumes that crude keeps flowing through pipelines that are still controlled at the valve level by whoever physically holds the site.
What the market did
Crude prices rose as the NOC statement circulated. Brent was quoted at $108.50 a barrel, about 2.7 percent above the previous reference price of $105.68, according to Trading Economics data on 15 September. OilPrice.com's quote board showed the US benchmark WTI up about 4.4 percent on the day and heating oil up about 6 percent. The move was part of a broader supply scare rather than a purely Libyan story: the same session also brought disruption to Saudi pipeline flows.
NOC framed its warning as an economic argument, not only an operational one. Oil revenues are the main source of funding for the state treasury, including public-sector salaries, and the company said halting production while world crude prices are rising would deal a blow to the national economy and damage Libya's reputation as a reliable global energy supplier. It rejected the use of production shutdowns to press demands, saying those should be pursued through legal channels and the relevant institutions, and called on state authorities to intervene urgently.
What the statements do not establish
Several things remain unquantified. Neither NOC nor the guard has published a volume figure for the output actually lost, so the share of Libya's 1.4 million barrels per day that is offline cannot be calculated from the statements. Force majeure has been threatened, not declared, and the partial cuts at Wafa, Al-Khamsa and El Feel were announced by the guard rather than confirmed by NOC. Nor is there confirmation from Libya's defence ministry or the Government of National Unity on the transfer demand at the centre of the dispute. Finally, because the price reaction coincided with other supply disruption, it is not possible to isolate how much of the Brent move is attributable to Libya alone.
