Abstract: A method for completing a wellbore extending through a subterranean formation may include installing a sandface completion assembly in the wellbore; pumping a solids free fluid comprising chemical precursors into an annulus formed between the subterranean formation and the sandface completion assembly; triggering and/or controlling chemical reaction between the chemical precursors to form a plurality of solid particles in the annulus.

Abstract: A water-free slurry may include a non-aqueous carrier fluid; a suspension agent including a mineral clay mixture; a crosslinking agent; and a hydratable polymer. A method of treating a subterranean formation may include injecting a water-free slurry into a wellbore penetrating the subterranean formation, the water-free slurry including: a non-aqueous carrier fluid; a suspension agent comprising a mineral clay mixture; a crosslinking agent; and a hydratable polymer.

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.
