Claim 10:
11. A method for increasing a rate of hydrocarbon production from a subsurface formation comprising:
producing a first rate of production of hydrocarbons from the subsurface formation;
introducing a hydraulic fracturing fluid comprising a plurality of coated proppants into the subsurface formation; and
increasing hydrocarbon production from the subsurface formation by producing a second rate of production of hydrocarbons from the subsurface formation, in which the second rate of production of hydrocarbons is greater than the first rate of production of hydrocarbons, and wherein
each of the plurality of coated proppants comprises a proppant particle, a surface copolymer layer surrounding the proppant particle, and a resin layer surrounding the surface copolymer layer,
the surface copolymer layer comprises a copolymer of at least two monomers chosen from styrene, methyl methacrylate, ethylene, propylene, butylene, imides, urethanes, sulfones, carbonates, and acrylamides,
the resin layer comprises a cured resin,
the surface copolymer layer has an interpenetrating 3D-crosslinked polymer network structure crosslinked by divinyl benzene, and
each of the plurality of the coated proppants has a fine production of from 0.1% to 10% at a closure stress of 10,000 psi.
