The White River Shale Project is a join project of Phillips Petroleum Company, Sunoco Energy Development Company, and Sohio Shale Oil Company. The intent of these owners is to develop Federal Oil Lease Tracts Ua and Ub in northeastern Utah to produce commercial quantities of shale oil. The project is planned for phased development over 12 years, at which time full commercial production will be achieved. Commercial operation will continue until the on-tract resources are exhausted. This is expected to occur in 2007. However, availability of other nearby oil shale resources may extend the life of the project substantially.
