    Abstract: Oil-contaminated clay dispersions in final tailings pond water from a bitumen extraction operation are used in downhole catalytic steam production for an in situ process such as SAGD to produce bitumen. The final tailings pond water is thus disposed of in an environmentally acceptable manner and a suitable source of water is made available for steam generation and subterranean injection.

    Abstract: Disclosed is a process for the upgrading of heavy oils and bitumens, where the total feed to the process can include heavy oil or bitumen, water, and diluent. The process can include the steps of solvent deasphalting (110) the total feed (105) to recover an asphaltene fraction (116), a deasphalted oil fraction (118) essentially free of asphaltenes, a water fraction (112), and a solvent fraction (114). The process allows removal of salts from the heavy oils and bitumens either into the aqueous products or with the asphaltene product.
