Plugging subterranean regions with acrylic-epoxy resin-forming emulsions
A subterranean formation 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 these polymers. The proportions of the materials are arranged to cause the emulsion to become a resinous plug after being emplaced. The proportions of the self-curing emulsion (of water, polyepoxy, and polycarboxy resin-forming polymers and reaction rate-controlling material) can be correlated with the temperatures and flow properties of subterranean regions so that the emulsions form resinous plugs having significant amounts of compressive strength after they have been flowed into the regions to be plugged. For example, a mass of loose sand having a permeability of 10 darcies and substantially no compressive strength was so treated to form an impermeable consolidated mass having a relatively high compressive strength of about 650 psi.
