Abstract
A method for producing a coated proppant having an intermediate cross-linked terpolymer layer includes mixing a monomers solution including a first monomer, a second monomer that is different from the first monomer, a cross-linking agent, and an initiator. The proppant particle is combined with the monomers solution, and the monomer solution on the surface of the at least one proppant particle is polymerized to form at least one proppant particle having the intermediate cross-linked terpolymer layer on a surface of the at least one proppant particle. A resin solution including an epoxy resin, a curing agent, and graphene is mixed, and combined with the at least one proppant particle having the intermediate cross-linked terpolymer layer on a surface of the at least one proppant particle. The resin solution is cured to form the coated proppant comprising an intermediate cross-linked terpolymer layer.
