Abstract
An aqueous based slurry is described comprising (1) a thickened water-based carrying fluid, (2) a particulate solid, e.g., gravel, and (3) a resin system comprising an epoxy resin and a novel crosslinking agent. The cross-linking agent is a polymethylene polyphenylamine bearing one or more silane groups of the formula --CH.sub.2 CH(OH)CH.sub.2 O--C.sub.3 -C.sub.6 alkylene --Si(OR').sub.3, wherein each R' independently is hydrogen or lower alkyl. This pumpable slurry is suitable 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.
