Abstract
Methods of preparing a crosslinked hydraulic fracturing fluid include combining a hydraulic fracturing fluid comprising a polyacrylamide polymer with a plurality of coated proppants. The plurality of coated proppants include a proppant particle and a resin proppant coating on the proppant particle. The resin proppant coating includes resin and a zirconium oxide crosslinker. The resin includes at least one of phenol, furan, epoxy, urethane, phenol-formaldehyde, polyester, vinyl ester, and urea aldehyde. Methods further include allowing the zirconium oxide crosslinker within the resin proppant coating to crosslink the polyacrylamide polymer within the hydraulic fracturing fluid at a pH of at least 10, thereby forming the crosslinked hydraulic fracturing fluid.
