Patent ID: 8227026

Claim:
A method comprising: manufacturing a fully cured coated proppant particle, the coated particle having an apparent density of about 1 to about 4 grams per cubic centimeter (g/cc), said manufacturing comprising: mixing at least one cold setting thermosetting resin curable at a temperature of less than or equal to about 65° C. selected from the group consisting of: epoxies, epoxies with a polyurethane, polyurethanes, alkaline modified resoles set by esters, furans, furfuryl alcohol-formaldehyde, urea-formaldehyde, and free methylol-containing melamines, with an inorganic substrate to form a mixture; and coating the inorganic substrate with the cold setting thermosetting resin to form a coating on the substrate, and fully curing the cold setting thermosetting resin prior to introduction into a subterranean formation, on the inorganic substrate by cold setting at a temperature of less than or equal to about 65° C. to produce the coated proppant particle; the inorganic substrate of a respective proppant particle comprising a single inorganic particle, the inorganic substrate comprising an inorganic material selected from the group consisting of inorganic oxides, inorganic carbides, inorganic nitrides, inorganic hydroxides, inorganic oxides having hydroxide coatings, inorganic carbonitrides, inorganic oxynitrides, inorganic borides, inorganic borocarbides.
