Largest U.S. refinery now belongs to Saudi Arabia

Royal Dutch Shell and Saudi Aramco appear to be getting a divorce, breaking up their joint venture in U.S.-based refining assets.

The two companies joined together to create Motiva Enterprises LLC in 1998, a 50-50 joint venture that operated three refineries on the U.S. Gulf Coast. But Shell and Saudi Aramco have seen their interests head in different directions. “It is now time for the partners to pursue their independent downstream goals,” said Abdulrahman Al-Wuhaib, a senior vice president of Saudi Aramco’s downstream unit.
