    Abstract: An underground reservoir is provided comprising an injection well and a production well. The production well has a horizontal section oriented generally perpendicularly to a generally linear and laterally extending, upright combustion front propagated from the injection well. The method relates to controlling location of inflow into a production well during in situ combustion. The horizontal section of the production well includes blocking agents to prevent well failure.

    Abstract: Methods are provided for enhancing hydrocarbon recovery through gas production control for noncondensable gases in SAGD or ES-SAGD operations. Steam may be injected into one or more injection wells to heat the hydrocarbons and reduce their viscosity to more easily produce the hydrocarbons. A noncondensable gas may be injected into the injection wells to beneficially reduce the steam-to-oil ratio, improving economic recovery. Unfortunately, excessive production of noncondensable gases can adversely suppress hydrocarbon production rates. To counteract this problem, gas production rates at the production wells may be controlled to optimize hydrocarbon output by limiting the produced gas-to-water ratio to certain limited ranges. The noncondensable gas may optionally comprise a combustion gas such as flue gas. By providing a useful application of existing combustion gases, green house gases emissions may be reduced. Advantages include higher efficiencies, lower costs, reduced hydrocarbon extraction time, and in some embodiments, reduced greenhouse gas emissions.

    Abstract: The present method produces treated water from a direct steam generator. The method begins by injecting water into a direct steam generator. The injected water is then vaporized with the direct steam generator to produce steam and an effluent stream. The combustible water impurities in the water are then combusted inside a chamber in the direct steam generator and the solid particles are removed from the effluent stream to produce a treated stream.

    Abstract: Methods and apparatus relate to producing hydrocarbons. Injecting a fluid mixture of steam and carbon dioxide into a hydrocarbon bearing formation facilitates recovery of the hydrocarbons. Further, limiting amounts of non-condensable gases in the mixture may promote dissolving of the carbon dioxide into the hydrocarbons upon contact of the mixture with the hydrocarbons.
