The pipeline, known as the Petroline, carries roughly four to five million barrels per day from the eastern oil fields at Abqaiq to the Red Sea port of Yanbu, making it one of the most strategically significant pieces of energy infrastructure on the planet. That volume represents approximately four to five percent of total global oil supply.
