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 process for hydrocarbon recovery performs a steam assisted gravity drainage (SAGD) operation by injecting steam in a steam injection well of a SAGD well pair and continuing to inject steam to establish fluid communication between the steam injection well and an oxidizing gas injection well that includes an oxidizing gas injection well segment that is spaced generally above the steam injection well segment, and producing hydrocarbons from a hydrocarbon production well of the SAGD well pair, the hydrocarbon production well including a generally horizontal production well segment disposed generally parallel to and vertically below a generally horizontal steam injection well segment of the steam injection well such that the steam injection well segment is disposed generally vertically between the production well segment and the oxidizing gas injection well segment.

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 apparatus is disclosed for use in a hydrocarbon production well that includes a casing extending from a segment of the production well to a wellhead. A production conduit extends inside the casing, from a first end in the hydrocarbon production well to a second end at the wellhead. A receptacle includes a bottom spaced from the first end of the production conduit and at least one sidewall extending around a portion of the production conduit proximal the first end such that the receptacle extends around the first end of the production conduit. The receptacle includes an opening for liquid to pass into the receptacle to separate liquids from gases. A submersible pump is disposed in the production well and includes a motor outside the receptacle and coupled to a pump body inside the receptacle to pump the liquid from a pump inlet in the receptacle, through the production conduit to the second end.

Abstract: A process for hydrocarbon recovery from an oil sands deposit includes injecting an oxidizing gas into an oil sands reservoir through an injection well. The oxidizing gas supports in situ combustion (ISC) in the reservoir. A generally horizontal well pair is used that is in fluid communication with the injection well to recover hydrocarbons mobilized by the ISC. The well pair includes: a generally horizontal segment of a hydrocarbon production well, and a generally horizontal segment of a combustion gas production well. The generally horizontal segment of the combustion gas production well is generally parallel to and spaced vertically above the horizontal segment of the hydrocarbon production well. The segment of the oxidizing gas injection well is spaced generally above the segment of the hydrocarbon production well and generally above the segment of the combustion gas production well.
