Abstract

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.
