Oil recovery by quenched in situ combustion

Patent ·
OSTI ID:5146389
An in situ combustion method of recovery hydrocarbon from an underground hydrocarbon formation penetrated by at least one injection well and at least one production well, is described which comprises: igniting the formation to form a combustion from by injecting oxygen-containing gas and heat into a hydrocarbon formation through an injection well; quenching the combustion front by injecting a sufficient amount of water into the formation through the injection well; reigniting the combustion front at a location farther away from the injection well than the previously quenched combustion front by injecting an oxygen-containing gas into the formation through the injection well; and recovering hydrocarbons and other fluids at a production well.
