ABSTRACT A pumpable slurry comprising (1) a thickened aqueous-based carrying fluid, (2) a particulate solid, and (3) a resin system comprising an epoxy resin and a crosslinking agent. The crosslinking agent is a poly- methylene polyphenylamine bearing one or more silane groups of the formula ----CH2CH(OH)CH2O---(C3-C6 alkylene)---Si(OR')3 , wherein each R' independently is hydrogen or lower alkyl. The slurry is sutitable for use in emplacing a permeable, consolidated gravel pack between the casing of a well and an incompetent subterranean formation. The slurry is easily formed on site by merely blending the components in an appropriate ratio using conventional equipment.
