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.

Abstract: A system, process and apparatus for delivering steam to a wellhead associated with a steam-assisted hydrocarbon recovery operation is disclosed. The process involves receiving a steam flow having a first steam quality at an inlet of a steam conduit, the inlet being located at a remote location with respect to the wellhead. The process also involves transporting the steam flow along the steam conduit to an outlet at the wellhead, the steam flow being subject to losses during transport along the steam conduit causing formation of condensate within the steam flow thereby reducing the steam quality at the outlet. The process further involves delivering a heat flux through a wall of the steam conduit, the heat flux being sufficient to cause at least a portion of the condensate to be vaporized before reaching the outlet of the steam conduit thereby increasing the steam quality to a second steam quality for delivery to the wellhead.

Abstract: Described herein is a method of producing heated water from a hydrocarbon reservoir. The method includes injecting water into at least a portion of the hot bitumen-depleted zone to heat the water; and producing the heated water from a heated water production well. The method can includes generating the hot bitumen-depleted zone using steam-assisted gravity drainage, in situ combustion, steam flooding, cyclic steam stimulation, a solvent aided thermal recovery process, electric heating, electromagnetic heating, or any combination thereof.

Abstract: An integrated thermal recovery process using a solvent of a pentane or hexane or both as an additive to, or sole component of, a gravity-dominated process for recovering bitumen or heavy oil from a reservoir. A pentane-hexane specific solvent fraction is extracted at surface from a diluent stream. That pentane-hexane solvent fraction is then injected into the reservoir as part of a gravity-dominated recovery process within the reservoir, and when that solvent fraction is subsequently produced as part of the oil or bitumen blend, it is allowed to remain within the blend to enhance the subsequent blend treating and transportation steps. Meanwhile, the remainder of the diluent from which the solvent stream had been extracted is utilized at surface as a blending stream to serve as an aid in treating of produced fluids and also to serve as a means of rendering the bitumen or heavy oil stream pipelineable.
