Abstract: Embodiments of the present disclosure are directed to a method of producing a viscoelastic surfactant (VES) fluid, the VES fluid comprising desulfated seawater. The method of producing the VES fluid comprises adding an alkaline earth metal halide to seawater to produce a sulfate precipitate. The method further comprises removing the sulfate precipitate to produce the desulfated water. The method further comprises adding a VES and one or more of a nanoparticle viscosity modifier or a polymeric modifier to the desulfated seawater. Other embodiments are directed to VES fluids that maintain a viscosity greater than 10 cP at temperatures above 250° F.

Abstract: A method for formulating a hydraulic fracturing fluid composition with increased viscosity and resistance to degradation at increased temperature and pressure. The method includes preparing an alkanolamine borate formulation compatible for mixing with a hydraulic fracturing fluid comprising polysaccharides; preparing the hydraulic fracturing fluid comprising polysaccharides; and mixing the alkanolamine borate formulation with the hydraulic fracturing fluid, such that the alkanolamine borate formulation causes crosslinking of the hydraulic fracturing fluid.

Abstract: A fracturing fluid including a mixture of an aqueous copolymer composition including a copolymer, the copolymer having 2-acrylamido-2-methylpropanesulfonic acid, acrylamide, and acrylic acid monomer units, or a salt thereof, and a crosslinker. The crosslinker includes a metal, and the weight ratio of the metal to the copolymer is in a range of 0.01 to 0.08. Treating a subterranean formation includes introducing the fracturing fluid into a subterranean formation, and crosslinking the fracturing fluid in the subterranean formation to yield a crosslinked fracturing fluid. The crosslinked fracturing fluid has a viscosity of at least 500 cP for at least 80 minutes when the gel is subjected to a shear rate of 40 s−1 at a temperature in a range of 300° F. to 400° F.

Abstract: A treatment fluid and method for water shut-off applications containing an amine-functionalized solid support, an epoxy resin, a second curing agent, and a carrier fluid. Prior to use of the treatment fluid, the amine-functionalized solid support has reacted with carbon dioxide to produce a carbamate-functionalized solid support. The treatment fluid is introduced into a geological formation with high-permeability pathways, curing the epoxy resin, and sealing these pathways.
