Abstract
In a method of propping a fracture in subterranean formations, the invention comprises placing in the fractures particulate solids such as sand coated with a water-repellent coating composition such as an oil-soluble organo-silicon compound. The water-repellent coated solid particulate propping agent can be prepared by dissolving an oil-soluble organo-silicon compound in a solvent therefor, admixing the resultant solution with particulate material, and thereafter evaporating the solvent to form a coating of organo-silicon compound on the particulate material.
