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: A method for reducing a permeability of at least one zone in a subterranean formation that includes introducing a treatment fluid to at least one permeable zone in a subterranean formation. The treatment fluid contains a solvent, a crosslinking agent, and a water-soluble polymer that is a copolymer of an acrylamide monomer and an n-vinyl amide monomer, or a terpolymer of an acrylamide monomer, an n-vinyl amide monomer, and an acrylic-acid based monomer. The treatment fluid is then allowed to crosslink and form a gel in the zone.

Abstract: A method is described for treating a formation adjacent a subterranean well with a treatment fluid composition imparted with emulsion formation prevention properties. A microemulsion additive is mixed into a treatment fluid component to form a volume of a treatment fluid composition having emulsion formation prevention properties. The microemulsion additive is composed of a mixture solvent, a co-solvent, a mutual solvent, a non-emulsifier, a non-ionic surfactant, a non-ionic co-surfactant, alcohol, an emulsifying surfactant, and an aqueous fluid. The volume of the fluid composition is then injected into the subterranean well and contacts the formation, whereby the microemulsion additive in the treatment fluid volume acts to prevent emulsion formation in the formation.
