The East-West Pipeline, also known as the Petroline, is a 746 miles (1,201 km)-long 48 inches (120 cm) pipeline that runs from the Abqaiq oil field in the Eastern Province (near Bahrain and Qatar on the Persian Gulf coast) across the width of the Arabian Peninsula to Yanbu at the Red Sea. It was built during the Iran-Iraq war in the 1980's to allow Saudi Arabian oil exports to bypass the tanker war and the Strait of Hormuz.

The line was converted to carry natural gas, but was converted back to carry crude oil.

The pipeline is actually twinned pipes, and as of 2018 had a capacity of 5 million barrels of oil per day (BPD) during normal operation. As of 2026, its full capacity was 7 million BPD when accompanying natural gas liquids pipelines are converted to carry crude oil. It was converted to full capacity on March 11, 2026, due to the 2026 Iran war and the associated closure of the Strait of Hormuz to non-Iranian vessels.

In normal times, the pipeline supplies 1 million BPD to the 3 refineries in Yanbu (Yanbu National Petrochemical Company and Aramco), some to the Sumed pipeline in Egypt, and 1.1—1.4 million BPD is exported of Arab Light oil through the King Fahd Industrial Port (Yanbu) with a limit of 3 million BPD.
