Particular aqueous gels, epoxy resin compositions and optional additives such as diluents, retarders and accelerators are described which produce a practical composition and method for in situ sand consolidation and gravel packing by which a resin coated sand is positioned in a desired location and cured by an internal catalyst to form a porous permeable or plugged consolidated mass.

DETAILED DESCRIPTION I claim: 1.
An epoxy resin composition for forming a porous permeable consolidated particulate mass, characterized as a mixture of an epoxy resin composition which comprises a polymerizable polyepoxide, optionally an organic diluent and a curing agent; an aqueous gel with a neutral polysaccharide polymer having a molecular weight of about 100,000-2,000,000 and water solubility sufficient to produce a viscosity of at least about 30 centipoise containing a mixture of surfactants comprising at least one cationic surfactant with limited water solubility and at least one noncationic water miscible surfactant which causes the epoxy resin to coat onto silica surfaces of the particulate material in the presence of the polysaccharide gel and which are present in an amount at least sufficient to coat onto said silica surfaces.
2.
A composition for filling a voide with consolidatable epoxy resin coated silica particles comprising a mixture of an aqueous fluid gelled with a neutral polysaccharide cellulose polymer having a molecular weight of about 100,000-2,000,000 and water solubility sufficient to produce a viscosity of at least about 30 centipoise; a mixture of surfactants present in an amount at least sufficient to coat onto said silica particles comprising at least one cationic surfactant with limited water solubility and at least one water miscible surfactant which is nonionic, anionic, neutralized cationic or a mixture thereof; said silica particles and an epoxy resin composition.
3.
A composition of claim 2 wherein the epoxy resin composition comprises a polymerizable polyepoxide, an organic diluent and a curing agent.
4.
A composition of claim 2 wherein the epoxy resin composition contains a retarder and a cationic surfactant.
5.
A composition of claim 2 wherein the epoxy resin composition contains a silane.
6.
A composition of claim 1 wherein the epoxy resin composition contains a retarder and a cationic surfactant.
7.
A composition of claim 6 wherein the epoxy resin composition contains a silane
