摘要
High permeability channels or wormholes found in hydrocarbon reservoirs having hydrocarbon-bearing formations can be remediated by heating the formation with dry, hot flue gases, injecting produced water into the formation through an injection well, and forming steam within the formation and spaced away from the injection well. The steam can be created at a steam generation interface occurring between a dry, hot gaseous drive front and an injected water front. Managing a quality of the steam formed along the steam generation interface, by increasing the combustion gas flow rate or decreasing the rate of water injection, allows for the initiation of precipitation and controlled deposition of solids dissolved in the produced water.
