Drone Attack Cripples Saudi East-West Pipeline, Prompting Reroutes and Market Volatility

Attack on Three Pumping Stations
On September 17, satellite imagery and three industry sources confirmed damage to three of the eleven pumping stations on Saudi Arabia’s 1,200 km (745-mile) East-West Pipeline in a drone strike launched from Iraq. The pipeline, operated by Saudi Aramco, was shut down temporarily, halting the flow of 4–5 million barrels per day (bpd) that normally bypasses the Strait of Hormuz. Saudi Aramco and the Saudi government media office did not comment.
Background & Context
Completed in 1981, the East-West Pipeline links the Ghawar and Abqaiq processing facilities to the Red Sea export hub at Yanbu, reducing reliance on the Hormuz chokepoint, which has been largely closed since the United States-Israel war with Iran began on February 28. With the line offline, Saudi crude must again traverse the Gulf and Hormuz or use longer routes through the Suez Canal or around the Cape of Good Hope.
Data & Statistics
- Capacity: Designed for about 7 million bpd; currently moving 4–5 million bpd.
- Damage: Three stations confirmed damaged; two stations were previously reported as hit.
- Repair outlook: Estimates range from a few days for partial flow to five-six weeks for full recovery.
- Market reaction: Brent futures slipped to $105-$106 per barrel; WTI fell to $100-$102 per barrel after the outage.
Impact on Global Oil Flows
The loss of up to 5 million bpd forced Saudi Arabia to reroute crude via ship-to-ship (STS) transfers off Oman’s Sohar port and to increase shipments through Hormuz. Analysts note higher freight costs and added security risks as Houthi forces have seized key Red Sea points.
- Alternative routes:
1. STS transfers near Sohar – allows Asian refiners to receive cargoes without transiting Hormuz.
2. Stored crude at Yanbu and Egyptian terminals (Ain Sokhna, Sidi Kerir) – can supply Europe via the Sumed Pipeline while stocks last.
3. Partial pipeline restart – expected at 40-60 % capacity within weeks, delivering 2.5-3 million bpd, with the remainder supplied by Hormuz lifts and dark-fleet activity.
The disruption has also pushed U.S. diesel prices above $6 per gallon, prompting debate in Washington over possible export bans.
Official Statements & Responses
U.S. Energy Secretary Chris Wright called the outage a “brief and temporary interruption” that “will be measured in days,” adding that Saudi Arabia took “quick action” to push more barrels through Hormuz with U.S. naval support. Saudi Aramco declined comment on the damage or repair timeline.
Criticism & Opposition
Senate Majority Leader John Thune (R-SD) suggested a potential ban on diesel exports to curb domestic price spikes, while critics warned such a ban could depress refinery utilization and raise gasoline prices.
Conflicting Reports & Gaps
What’s Next
Saudi officials aim to restore roughly half of the pipeline’s capacity within the next few days and full capacity in about six weeks. The kingdom continues to offer additional crude to Asian buyers via STS transfers off Oman while monitoring security developments in Hormuz and the Bab al-Mandeb. U.S. and Gulf leaders are slated to meet next week to discuss de-escalation steps.
