Waterflooding method
A method for waterflooding subterranean hydrocarbon- containing formation is related. The method is to relate to a partially plugging portion of a formation with gel particles to improve the efficiency of waterflooding a hydrocarbon-containing formation. Mixtures of surfactant and flood water are injected downwardly through the injection well and into the hydrocarbon- containing formation. At least a portion of this flood water and surfactant mixture to be injected is mixed with a volume of gel particles and the resultant slug of material is preferably intermittently injected into the formation. However, it should be understood that the gel particles can be injected continuously, substantially continuously, or at various regular or irregular intervals. The volume of gel material to be injected and mode of injection is generally selected after a study of the properties of the hydrocarbon-containing formation.
