Method for controlling the permeability of a subterranean formation by the use of an aqueous colloidal dispersion

A stabilized latex dispersion is injected into the subterranean formation. The dispersion may subsequently be de-stabilized by a rise in temperature and contacted with the oil phase, resulting in inter-agglomeration of the colloidal particles. The stabilizing agent is a surfactant. The process modif...
