Saudi Arabia has restored full pumping capacity on the East-West pipeline — also known as the Petroline — returning throughput to 7 million barrels per day following Iranian drone strikes that knocked out one of its eleven pumping stations in early April. The restoration was confirmed by the kingdom’s Ministry of Energy and represents the completion of a contingency plan decades in the making.

The pipeline was built during the Iran-Iraq War in the 1980s, designed precisely for this scenario: a hostile power threatening the Strait of Hormuz. Running 1,200 kilometers across the Arabian Peninsula from the Abqaiq processing hub in the Eastern Province to the Red Sea port of Yanbu, it moves Saudi crude entirely overland, rendering the strait irrelevant to the kingdom’s export capacity. In 2026, accompanying natural gas liquids pipelines were converted to carry crude oil, raising total capacity from 5 million to 7 million barrels per day.

Saudi Aramco processes more oil through fewer facilities than any other company on earth. The Abqaiq oil processing facility in the Eastern Province handles a majority of Saudi crude production, stabilizing and processing it before it moves to export terminals. Ras Tanura is the largest oil loading port in the world. These facilities — concentrated, critical, and heavily defended — represent the upstream end of a supply chain whose downstream end runs through Hormuz. An attack on Abqaiq or a closure of the strait produces the same downstream effect: Saudi crude stops reaching its buyers. The two risks are linked by geography even when they originate from different threats.
