Abstract
A method of producing heated water from a reservoir having a hot bitumen-depleted zone adjacent to an aqueous mobile zone. The method includes generating fluid communication between the aqueous mobile zone and the hot bitumen-depleted zone. The method further includes driving water from the aqueous mobile zone through a portion of the hot bitumen-depleted zone to heat the water to produce heated water from a heated water production well.
