ABSTRACT:
A method of recovering hydrocarbon from an argillaceous subterranean rock formation involving the flooding of the formation with an aqueous fluid to displace the hydrocarbon from the formation. The method involves first subjecting the formation to an acid stimulation treatment by injecting a strongly acidic solution to dissolve acid soluble pore clogging materials, although this first step can be omitted, if desired. The formation is then treated with a solution containing an acid, a surfactant and a clay stabilizing agent. The concentration of the treatment solution is initially quite high but is gradually reduced until a certain threshold concentration is reached, after which a treatment solution having this threshold concentration is continuously injected into the formation to displace the hydrocarbon. The ingredients of the treatment solution exhibit a synergistic effect in maintaining a desirable rock permeability and a favorable mobility ratio between the treatment solution and the displaced hydrocarbons.
