Abstract: Methods include introducing a multistage treatment fluid into one or more intervals of a wellbore, wherein the treatment fluid contains one or more stages of a polymer-forming composition and one or more stages of a spacer fluid and initiating polymerization of the one or more stages of polymer-forming composition. Methods may include designing a multistage treatment fluid containing one or more stages of a polymer-forming composition and one or more stages of a spacer fluid, wherein or more stages of the polymer-forming composition comprises a thermosetting polymer; and pumping the multistage treatment fluid into a wellbore, wherein the pumping rate is determined by constructing a model based upon (a) the minimum pumping rate determined from the critical reaction temperature and the downhole temperature, (b) the fracture closing time, (c) the temperature within one or more fractures, and (d) the maximum pumping rate.

Abstract: Methods may include contacting a degradable polymer in a wellbore traversing a subterranean formation with a treatment fluid, wherein the treatment fluid is formulated with one or more polymer degrading catalysts; and allowing the degradable polymer composite to at least partially degrade. In another aspect, methods may be directed to designing a wellbore treatment that includes determining at least one degradation characteristic for one or more degradable polymers; formulating an aqueous treatment fluid based on the determined values, wherein the aqueous treatment fluid comprises one or more polymer degrading catalysts; contacting the degradable polymer with an aqueous fluid; and allowing the degradable polymer to at least partially degrade the degradable polymer.
