Why Saudi Arabia’s East-West pipeline matters for global oil

What the report says

Saudi Arabia has temporarily shut its East-West oil pipeline after drones struck the line last Thursday, according to Al Jazeera, citing Saudi officials and Reuters. The 1,200km route, also known as the Petroline, connects eastern oil fields to the Red Sea port of Yanbu and is important because it allows Saudi crude to reach export markets without passing through the Strait of Hormuz.

The reported shutdown comes amid wider disruption to regional energy shipping, including reduced flows through Hormuz and attacks in the Red Sea area. Al Jazeera said Saudi Arabia’s Energy Ministry described the move as a precaution after damage and injuries were reported in the Riyadh and Medina regions. The outlet also reported that the origin of the drones was traced by Saudi authorities to Iraq’s Maysan province, near the Iranian border, where Iran-aligned armed groups are said to have operated for years.

The pipeline is a major part of Saudi Arabia’s oil system, with a maximum capacity of about 7 million barrels per day. Al Jazeera said recent westbound flows had been lower than that maximum but still accounted for around 4% to 5% of global oil supply when Saudi Arabia increased shipments to the Red Sea earlier in the conflict. Reuters sources cited by Al Jazeera gave differing views on repair time, ranging from a restart within days to five or six weeks.

The development matters because global oil markets are already tight, inventories have been falling, and Saudi Arabia has been leaning on the pipeline and Yanbu to offset risks elsewhere. Al Jazeera’s reporting suggests a prolonged outage could further constrain exports and put upward pressure on prices.
