Abstract
The invention provides a method of treating a subterranean formation, comprising placing a composition comprising proppant particles into the subterranean formation, wherein at least a portion of proppant particles is coated with a hardened resin that is a cured product of a curable composition comprising: (A) a curable resin and (B) a hardening agent.
Claims15
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, 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;
- 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.
4 more elements
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.
