摘要： Methods enhance hydrocarbon recovery through gas production control for noncondensable gases in SAGD or ES-SAGD. Steam injected into one or more injection wells heats the hydrocarbons and reduces their viscosity to more easily produce the hydrocarbons. A noncondensable gas may be injected into the injection wells to reduce the steam-to-oil ratio, improving economic recovery. Excessive production of noncondensable gases can adversely suppress hydrocarbon production rates. To counteract this problem, gas production rates may be controlled by limiting the produced gas-to-water ratio. The noncondensable gas may comprise a combustion gas such as flue gas. Advantages include higher efficiencies, lower costs, reduced hydrocarbon extraction time, and in some embodiments, reduced greenhouse gas emissions.

摘要： Methods relate to producing hydrocarbons, such as bitumen in an oil sands reservoir. The methods include utilizing an injector well with multiple horizontal laterals to provide downward fluid drive toward a producer well. Combined influence of gravity and a dispersed area of the fluid drive due to the laterals facilitate a desired full sweep of the reservoir. Fluids utilized for injection include water heated to less than 60 weight percent steam, solvent for the hydrocarbons and emulsifying agent for the hydrocarbons. The methods employing these fluids provide energy efficient recovery of the hydrocarbons.
