A method is described of providing sand control of underground formations penetrated by at least one well borehole by forming an epoxy resin consolidated sand or gravel pack of high compressive strength. A slurry of sand, that has been coated with a solution of an epoxy- containing resin-forming material and a curing agent dissolved in a polar liquid solvent and suspended in a suitable liquid carrier, such as a hydrocarbon liquid is injected into the well. The resin has a limited solubility and a limited capacity for extracting the polar solvent from the resin-forming material. The curing or polymerization reaction rate of the resin-forming components, under the borehole and formation temperature conditions, is thus controlled so that the final setting of the resin and the consolidation of the gravel pack and adjacent portions of the formation is achieved while the sand or gravel pack is in place.
