Methods of treating a subterranean formation with stress-activated resins

摘要

Methods of treating a subterranean formation including introducing a fracturing fluid into the subterranean formation at a pressure sufficient to create or enhance at least one fracture therein; a treatment fluid comprising a base fluid, proppant particulates, a crosslinking agent, and a stress-activated resin comprising a stress-activated moiety, wherein the stress-activated resin does not substantially react with the crosslinking agent until placed under stress; introducing the treatment fluid into the at least one fracture of the subterranean formation; removing the pressure in the subterranean formation such that the fracture closes on the treatment fluid and applies a stress to the stress-activated resin; and crosslinking the resin with the crosslinking agent, thereby forming a resinous proppant pack therein.

1. A method of treating a subterranean formation comprising:
introducing a fracturing fluid into the subterranean formation at a pressure sufficient to create or enhance at least one fracture therein; providing a treatment fluid comprising a base fluid, proppant particulates, a crosslinking agent, and a stress-activated resin comprising a stress-activated moiety, wherein the stress-activated resin does not substantially react with the crosslinking agent until placed under stress where it undergoes a conformational change, and wherein the stress-activated resin is selected from the group consisting of a polybutadiene polymer, a polybutadiene derivative polymer; a spiropyran polymer; a spiropyran derivative polymer; a poly(allyl halide) polymer; a poly(allyl halide) derivative polymer; a polycyclic halide containing polymer; a copolymer thereof; a cyclopropene; a cyclobutene; a 1,3-cyclohexadiene; a 1,4 cyclohexadiene; a 1,5-cyclooctadiene; a cyclopropane; a cyclobutane; a cycloheptane; any derivative thereof; and any combination thereof; introducing the treatment fluid into the at least one fracture of the subterranean formation; removing the pressure in the subterranean formation such that the fracture closes on the treatment fluid and applies a stress to the stress-activated resin; and crosslinking the resin with the crosslinking agent, thereby forming a resinous proppant pack therein.
