Libya's Sharara Oilfield Disrupted by Armed Group Pipeline Valve Closure Amid Broader Supply Risks

Libya’s National Oil Corporation (NOC) confirmed on September 21, 2026, that an armed military group closed Valve No. 7 on the pipeline from the Sharara oilfield to Zawiya port, sharply reducing output at the country’s largest field. Production fell from around 300,000-340,000 barrels per day (bpd) to approximately 100,000-120,000 bpd due to pressure buildup, with full shutdown possible if unresolved. The NOC warned of potential force majeure declarations, economic harm from lost revenues amid rising global prices, and risks to the Zawiya refinery, which could necessitate increased fuel imports. This incident follows recent disruptions, including earlier valve closures at Sharara and El Feel fields linked to pro-Haftar groups, and aligns with patterns of militia interference that have repeatedly halted Libyan production since 2011. Reuters and other outlets reported engineer estimates of a ~200,000 bpd drop, while the NOC urged the Petroleum Facilities Guard to intervene without success so far. The event compounds global supply pressures from Middle East tensions, including Strait of Hormuz uncertainties and prior Red Sea pipeline issues, contributing to Brent crude trading above $100 in recent sessions.
