ABSTRACT:
A subterranean region is plugged by flowing into it an aqueous emulsion containing an epoxy-resin-forming polyepoxy polymer, an acrylic-resin-forming polycarboxy polymer, and a material for controlling the rate of the interaction of said polymers, with the proportions of said materials arranged to cause the emulsion to become a resinous plug after being emplaced.
