wherein the curable composition is cured prior to placing the composition into the subterranean formation; and wherein the placing comprises contacting the at least partially coated proppant particles with the subterranean formation thereby treating the subterranean formation. ### Claim 2 (depends on 1) The method of claim 1, wherein the weight ratio of the curable resin to the hardening agent is about 6:4 to about 7:3. ### Claim 3 (depends on 1) The method of claim 1, wherein the curable resin comprises the product of reaction in the absence of water between epichlorohydrin, bisphenol A, and the plant oil, and wherein the hardening agent comprises diethyl toluene diamine. ### Claim 4 (depends on 3) The method of claim 3, wherein the plant oil comprises an oil selected from the group consisting of a vegetable oil, an epoxidised vegetable oil, an epoxy derivative of a monoglyceride of vegetable oil, fruit oil, wood oil, and any combination thereof. ### Claim 5 (depends on 3) The method of claim 3, wherein the plant oil comprises an oil selected from the group consisting of linseed oil, soybean oil, palm oil, coconut oil, argemone oil, pongamia oil, jatropha oil, laurel oil, neem oil, cottonseed oil, vernonia oil, Annona squamosa oil, Catunaregam nilotica oil, rubber seed oil, crabe oil, J. curcas oil, rapeseed oil, canola oil, sunflower oil, safflower oil, maize oil, sandalwood oil, castor oil, jojoba oil, peanut oil, cashew oil, sesame oil, olive oil, candle nut oil, and any combination thereof. ### Claim 6 (depends on 3) The method of claim 3, wherein the plant oil comprises soybean oil, and wherein the hardened resin is in a concentration of about 2 wt % to about 3 wt %, based on the total weight of the composition. ### Claim 7 (depends on 1) The method of claim 1, further comprising performing a gravel packing when placing the composition into the subterranean formation. ### Claim 8 (depends on 1) The method of claim 1, further comprising fracturing the subterranean formation to form at least one fracture in the subterranean formation. ### Claim 9 (depends on 1) The method of claim 1, wherein the composition further comprises a carrier fluid. ### Claim 10 (depends on 9) The method of claim 9, wherein the carrier fluid comprises a compound or composition selected from the group consisting of crude oil, dipropylene glycol methyl ether, dipropylene glycol dimethyl ether, dipropylene glycol methyl ether, dipropylene glycol dimethyl ether, dimethyl formamide, diethylene glycol methyl ether, ethylene glycol butyl ether, diethylene glycol butyl ether, butylglycidyl ether, propylene carbonate, D-limonene, a C2-C40 fatty acid C1-C10 alkyl ester, tetrahydrofurfuryl methacrylate, tetrahydrofurfuryl acrylate, 2-butoxy ethanol, butyl acetate, butyl lactate, furfuryl acetate, dimethyl sulfoxide, dimethyl formamide, diesel, kerosene, napthas, mineral oil, or any combination thereof. ### Claim 11 (depends on 1) The method of claim 1, further comprising combining the composition with an aqueous or oil-based fluid comprising a fracturing fluid, spotting fluid, clean-up fluid, completion fluid, remedial treatment fluid, abandonment fluid, pill, cementing fluid, packer fluid, or a combination thereof. ### Claim 12 (depends on 1) The method of claim 1, wherein the proppant particles comprise sand. ### Claim 13 (depends on 1) The method of claim 1, further comprising: placing a tubular in the subterranean formation; and pumping the composition through the tubular and into the subterranean formation using a pump. ### Claim 14 A system for practicing a method of treating a subterranean formation, the system comprising: a tubular disposed in the subterranean formation; and a pump configured to pump a composition into the subterranean formation through the tubular, the composition comprising: proppant particles, wherein each of the proppant particles is at least partially coated with a hardened resin comprising a cured product of a curable composition, wherein the hardened resin is in a concentration of about 2 wt. % to about 4 wt. %, based on the total weight of the composition, and wherein the curable composition comprises: a cured product of a curable composition, wherein the hardened resin is in a concentration of about 2 wt. % to about 4 wt. %, based on the total weight of the composition, and wherein the curable composition comprises: a curable resin comprising a product of reaction in the absence of water between epichlorohydrin, bisphenol A, and a plant oil, and a hardening agent comprising diethyl toluene diamine, wherein a weight ratio of the curable resin to the hardening agent is about 4:2 to about 8:2, and the method comprising: placing the composition comprising the proppant particles into the subterranean formation; wherein the curable composition is cured prior to placing the composition into the subterranean formation; and herein the placing comprises contacting the at least partially coated proppant particles with the subterranean formation thereby treating the subterranean formation. ### Claim 15 A method of treating a subterranean formation, comprising: placing a composition comprising proppant particles into the subterranean formation, wherein each of the proppant particles is at least partially coated with a hardened resin comprising a cured product of a curable composition, and wherein the curable composition comprises: a curable resin comprising a product of reaction in the absence of water between epichlorohydrin, bisphenol A, and a plant oil, and a hardening agent comprising diethyl toluene diamine, wherein a weight ratio of the curable resin to the hardening agent is about 6:4 to about 7:3; wherein the curable composition is cured prior to placing the composition into the subterranean formation; and wherein the placing comprises contacting the at least partially coated proppant particles with the subterranean formation thereby treating the subterranean formation.
