Saudi Arabia’s East-West pipeline, known as Petroline, is expected to resume operations within days after a drone attack forced a precautionary shutdown around September 10-11. US Energy Secretary Chris Wright said partial flows could return quickly, although full repairs may take several weeks. The 1,200-kilometer pipeline links Persian Gulf oil fields with Yanbu on the Red Sea and allows Saudi Arabia to bypass the Strait of Hormuz, through which roughly 20% of the world’s petroleum passes each day. Petroline has a maximum design capacity of 7 million barrels per day, while estimated flows before the shutdown ranged from 2.6 million to 5 million bpd. A separate attack in April 2026 cut output by 700,000 bpd, but Saudi operators restored full capacity within days. Market participants are focused on how quickly flows restart and whether initial throughput is closer to 2 million or 5 million bpd, as the difference between a partial restart and full restoration could shape oil-price moves.
