Abstract:
A nanoparticle-resin coated frac sand composition is provided. The nanoparticle-resin coated frac sand composition includes a silica sand, an epoxy resin, methanol, a hardener, and nanoparticles. The nanoparticles may be silica nanoparticles, alumina nanoparticles, zinc oxide (ZnO) nanoparticles, or titanium oxide (TiO2) nanoparticles. The methanol is used as a diluent for the epoxy resin. The nanoparticle-resin coated frac sand composition may be used as a proppant in a hydraulic fracturing operation, such by injecting a hydraulic fracturing fluid having the composition into a subterranean formation. Methods of manufacturing the composition and hydraulic fracturing of a subterranean formation are also provided.
