摘要： Viscosifying proppants including proppant particles coated with a CO2-philic coating in which the CO2-philic coating has a solvable portion that viscosifies a CO2-based fluid when the viscosifying proppant is added to the CO2-based fluid are provided. Methods of making viscosifying proppants are also provided that include coating proppant particles with a precursor material of a CO2-philic material, and polymerizing the precursor material to form a viscosifying proppant. Viscous hydraulic fracturing fluids include a CO2-based fluid and the viscosifying proppants and methods of treating subterranean formations that include contacting a subterranean formation with a viscous hydraulic fracturing fluid and propagating at least one subterranean fracture are also provided.

摘要： Gelled fluids include a gellable organic solvent, an aluminum crosslinking compound, and a mutual solvent. The gelled fluids may be prepared by combining an aluminum crosslinking compound and a first volume of a gellable organic solvent to form a pre-solvation mixture; gelling the pre-solvation mixture to form a pre-solvated gel; combining the pre-solvated gel with a formulation fluid to form a gellable mixture, the formulation fluid comprising a second volume of the gellable organic solvent; and gelling the gellable mixture to form the gelled fluid.

摘要： 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.
