Saudi Arabia Reroutes Crude via Oman After East-West Pipeline Attack
By Drooid · · How we work
Core Event
On September 11 2026 drone strikes damaged two pumping stations on Saudi Arabia’s East-West pipeline, halting loadings at Yanbu and prompting Riyadh to cancel several September cargoes to Europe. Saudi Aramco responded by offering additional crude to Asian refiners through ship-to-ship (STS) transfers off Oman’s Sohar port, reported on September 16-17. The move eased supply-tightness concerns, and Brent and WTI slipped 1–2 % on September 17, though both remained above $100 per barrel.
Background & Context
The 1,200-km East-West pipeline, built in the 1980s, provides a Red Sea export route that bypasses the Strait of Hormuz. Since the U.S.–Israel attacks on Iran in February 2026, Hormuz traffic has been reduced, increasing Saudi reliance on the pipeline. Houthi militants, backed by Iran, have repeatedly struck Saudi energy infrastructure, raising fears of a broader regional supply squeeze.
Timeline
- September 11 2026 – Drone attacks damage two pumping stations; fire damage visible in satellite imagery.
- September 13 2026 – Satellite images compare the pipeline before and after the attack.
- September 16 2026 – Oil prices fall as reports emerge of extra crude shipments via Oman. Brent at $107.06, WTI at $103.23.
- September 17 2026 – Prices ease further; Brent at $103.95, WTI at $100.66 after STS transfers are confirmed.
Data & Statistics
- Pipeline capacity – Designed for up to 7 million bpd; recent flow was 4–5 million bpd before the attack.
- Brent price range – $103.95 (Reuters, Sept 17), $105.89 (Oilprice, Sept 17), $105.70 (HDFCsky, Sept 17).

- U.S. crude inventories – Rose by 7.1 million barrels in the week ended September 11, contrary to expectations for a 1.6 million-barrel draw.
- Ship-to-ship transfers – Conducted off Sohar, allowing Saudi crude to reach Asian markets without transiting Hormuz.
Official Statements & Responses
- U.S. Energy Secretary Chris Wright called the outage “a brief and temporary interruption,” expecting restoration within days.
- Saxo Bank analysts warned that increased flows through Hormuz “only partly offset” the loss from the damaged pipeline.
Conflicting Reports & Gaps
- Price figures differ across outlets, reflecting rapid market swings and varying data cut-offs.
- Pipeline throughput is variably described as 4 million, 5 million, or the full 7 million bpd design capacity, leaving the exact volume lost unclear.
- Repair timeline remains unspecified; sources note it is “unclear,” with no official restart date disclosed.
