# East-West Crude Oil Pipeline The **East-West Crude Oil Pipeline**, historically called **Petroline**, is the roughly **1,200-kilometer (about 750-mile)** line that carries Saudi crude across the Arabian Peninsula from the Abqaiq processing complex in the Eastern Province to the Red Sea port of **Yanbu**. It is operated by the majority state-owned [[Aramco]]. Its full pumping capacity is about **seven million barrels a day**. The pipeline exists for one reason: to move Saudi oil to market **without passing through the [[Strait of Hormuz]]**. For most of its life that was insurance. Since February 2026 it has been the policy. ## Why it is the load-bearing piece of the war's energy geometry The [[Iran War 2026]] closed the Gulf exit. With Hormuz largely shut, Saudi Arabia — the world's largest oil exporter — rerouted the crude it could no longer ship east onto the pipeline and out through the Red Sea instead. Reuters data cited by *Al Jazeera* put recent throughput at **four to five million barrels a day, roughly 4 to 5 percent of global supply**; the line's capacity had been raised specifically to absorb the Hormuz disruption. That produced a single-string dependency. Saudi crude reached the world by exactly one route, and that route ran the length of the pipeline and then out through the [[Bab el-Mandeb]]. In the second week of September 2026 both ends were attacked in the same forty-eight hours. > [!note] The bypass and the chokepoint are one system > A bypass route only bypasses if its own exit stays open. The [[Houthis]] took the Yemeni side of the Bab el-Mandeb on September 10–11; drones hit the pipeline feeding it on September 10–11. Treating the pipeline and the strait as separate stories misses that they are the upstream and downstream halves of the same single remaining artery. ## The September 2026 attack and shutdown | Date | Development | |------|-------------| | April 2026 | A pumping station on the pipeline is struck, and throughput falls to about **700,000 barrels a day**. Saudi Arabia announces the line restored to full capacity **three days later**. Reported by *Al Jazeera*. | | July 29, 2026 | The United States and Saudi Arabia carry out **joint strikes on the Iran-backed [[Iraqi PMF]] across seven Iraqi provinces**, killing at least 20, after Saudi Arabia attributes earlier drone attacks on its oil facilities to Iraq-based groups. Iraq's National Security Council calls the strikes a violation of its sovereignty. | | September 10, 2026 | Satellite imagery from EU Copernicus Sentinel-3 shows **black smoke rising from the pipeline south of Medina**, and NASA FIRMS detects unusual thermal activity in the same area. | | September 11, 2026 | The Saudi **Ministry of Foreign Affairs** says the pipeline was hit by drones in the **Riyadh and Medina areas**, causing injuries and damage; equipment used to operate the line was also struck. The **Ministry of Energy** announces the pipeline has been **temporarily shut as a precaution** while specialized teams secure it and assess its safety. | | September 11, 2026 | The attack is attributed to drones **launched from the southeastern Iraqi province of Maysan**, per the office of Iraqi prime minister Ali al-Zaidi. **No group claims responsibility.** | | September 12, 2026 | Iraq condemns the attack, saying it does not accept its territory being used as a launchpad, orders a **probe of the Maysan operations command and dismisses its commander**, and closes **three border crossings with Iran** — Shalamcheh in Basra, al-Shib in Maysan, and Mandali in Diyala. | | September 12, 2026 | Saudi Arabia says it will hold off responding "at this stage" **at the Iraqi prime minister's request**, while reserving the right to take all measures necessary. | > [!warning] The attack date is reported two ways > Satellite and thermal detection place fires on the line on **September 10**; the Saudi announcement, and most wire coverage, dates the strike to **Friday, September 11**. The vault records both rather than collapsing them, because the shutdown announcement and the strike are separate events that may not share a date. ## Who is thought to have done it, and why No group claimed the attack and neither Riyadh nor Baghdad has publicly named a suspect. Iraq hosts numerous Iran-backed armed groups. Wolfgang Pusztai, a security and defence analyst, told *Al Jazeera* he believed the strike was most likely ordered from Tehran, and read its purpose two ways at once: pressuring Saudi Arabia to withdraw from Yemen, and sealing the Hormuz blockade by denying the kingdom the bypass. On his reading the second is the more consequential — it signals that no Gulf producer's workaround is out of reach. ## What it means for prices Ben Cahill of the Atlantic Council Global Energy Center called the pipeline Saudi Arabia's "principal bypass option to avoid the Strait of Hormuz" and the shutdown "a real blow," adding that "the key buffers that got us through the last six months have basically been worn away." Saudi analyst Khalid Bartafi framed the exposure as five million barrels of export capacity disappearing from the market and warned that the next 48 hours would determine whether the incident stayed contained. The market reaction was not linear. Brent crude peaked near **$108 a barrel on Thursday, September 10** — its highest since May — then **settled down 2.8 percent at about $104.61 on Friday, September 11**, after Iranian state media said Tehran would meet Gulf states in Oman to discuss the [[Strait of Hormuz]]. The week still closed with a **gain of roughly 8.7 percent** and Brent above $100 for the first time in months. Brent traded near **$72** before the war began on February 28, 2026, and hit **$119** early in the conflict. > [!warning] HCR's rendering of the Friday price is not corroborated > *Letters from an American* of September 11, 2026 says "the price of oil briefly jumped to about $110 a barrel on Friday." Settlement data for Friday, September 11 has Brent **down** 2.8 percent at about $104.61, with the $108 peak falling on Thursday. An intraday spike above $110 is not established by any source located here. This page carries the settlement figures. ## What Saudi Arabia can do instead Very little, quickly. The kingdom cannot redirect eastern crude to Yanbu while the line is shut, and the western stocks it can draw on still have to leave through a Red Sea whose southern gate the [[Houthis]] now command. The likeliest workaround is rerouting more exports through Egypt — the Suez Canal, or the 320-kilometer Sumed pipeline from the Red Sea to the Mediterranean. The Cape of Good Hope remains available and remains slow. How fast the line comes back is unknown. The April precedent was three days, but Saudi Arabia has not described the damage this time. As of the September 16 industry warnings below, the line is still shut. ## The traders' verdict — September 16, 2026 Five days after the shutdown, senior executives from **Shell** and **Equinor** put the structural reading on the record: global energy markets face a lengthening period of tight supply and price volatility because the industry's capacity to offset Middle East disruptions is running out. Shell Trading's chief economist: *"those shock absorbers are weakening."* Crude moved toward **$110** on the week, the first time since May, with refined products rising harder still and diesel at records. Two points in that assessment matter more than the price: - **Reopening a chokepoint does not restore the market.** Bottlenecks across shipping, production and supply chains could delay normal conditions **well into 2027**, and restocking would draw on supply beyond that. The damage outlives the blockade — which means the [[Gas Prices]] transmission the vault has been tracking does not reverse on the day the pipeline restarts. - **Europe is exposed through a different chokepoint.** Equinor CEO Anders Opedal noted European gas storage far below seasonal averages going into winter, with prices turning on weather, LNG flows through the [[Strait of Hormuz]], and competition with Asia for cargoes. The [[Houthis]] separately threatened the **[[Bab el-Mandeb]]** approach again, putting another roughly 4% of world oil supply at risk — a figure that reaches the vault through *Letters from an American* of September 16, 2026 and is not independently corroborated here, so it is noted rather than carried as a datum. On the same day the [[Federal Funds Rate]] went up a quarter point, explicitly against elevated inflation of which war-driven energy was the largest single monthly contributor. That is the full chain now written down end to end: a pipeline in the Saudi desert, a strait held by a proxy, a record diesel price, and a central bank raising the cost of money in Washington. ## See Also - [[Strait of Hormuz]] - [[Bab el-Mandeb]] - [[Aramco]] - [[Saudi Arabia]] - [[Houthis]] - [[Iran War 2026]] - [[Iran War 2026 Timeline]] - [[Iraqi PMF]] - [[Islamic Revolutionary Guard Corps]] - [[Gas Prices]] - [[Affordability]] - [[OPEC]]
