ABSTRACT:
Openings such as the pores of a permeable subterranean earth formation are plugged by inflowing a slurry of fine solid particles suspended in an aqueous emulsion that contains a dispersed oil-phase solution of a polyepoxide, an aminosilane, and a tertiary nitrogen-containing amine which is capable of causing the polyepoxide to polymerize while causing the particles to become oil-wet.
