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.
