Motiva Enterprises, LLC, is a 50–50 joint venture between Shell Oil Company (the wholly owned American subsidiary of Royal Dutch Shell) and Saudi Refining (controlled by Saudi Aramco). The company is currently headquartered in Houston, Texas, United States. Motiva Enterprises posted revenue of $24 billion during fiscal 2004. In 1988 Texaco and Saudi Refining agreed to form a joint venture known as Star Enterprise in which Saudi Refining would own a 50 percent share of Texacos refining and marketing operations in the eastern United States and Gulf Coast. In 1997 Shell embarked on two joint ventures with Texaco where the companies merged their marketing and refining operations. The operations in the western and midwestern United States were merged into a company called Equilon. The Star Enterprise operation and Shells eastern and southeastern operations were merged into a company called Motiva. After Texaco merged with Chevron in 2001, Shell and Saudi Refining purchased Texacos interests in the joint ventures. Equilon became a fully owned subsidiary of Shell, while Saudi Aramco and Shell each became equal owners of Motiva.
