Abstract: Techniques for hydraulically fracturing a geologic formation include circulating a proppant-free hydraulic fracturing liquid into a wellbore that is formed from a terranean surface into a geologic formation within a subterranean zone that is adjacent the wellbore; fluidly contacting the geologic formation with the proppant-free hydraulic fracturing liquid for a specified duration of time; and subsequent to the specified duration of time, circulating a hydraulic fracturing liquid that includes proppant into the wellbore to fracture the geologic formation.

Abstract: A fracturing fluid system for increasing hydrocarbon production in a subterranean reservoir formation comprising a fluid composition and a base fluid, the fluid composition comprising a nano-crosslinker, and a base polymer; and the base fluid operable to suspend the fluid composition, the base fluid comprising water; wherein the fluid composition and the base fluid are combined to produce the fracturing fluid system, wherein the fracturing fluid system is operable to stimulate the subterranean reservoir formation. In certain embodiments, the nano-crosslinker is an amine-containing nano-crosslinker and the base polymer is an acrylamide-based polymer. In certain embodiments, the fracturing fluid systems comprise proppants for enhancing hydraulic fracturing stimulation in a subterranean hydrocarbon reservoir.

Abstract: A subterranean zone can be treated by introducing an acid-generating material and a proppant to the subterranean zone. Fractures are created in the subterranean zone using the acid-generating material. The proppant is positioned within the created fractures to keep the fractures open.

Abstract: Systems and methods for producing fluids from a subterranean well include introducing expandable beads into a target region of a production zone of the subterranean well, the expandable beads being formed of thermally expandable material in an unexpanded condition with a first diameter. A radial confining stress is increased and a hoop stress is decreased within the target region by thermally expanding the expandable beads so that the beads are in an expanded condition with a second diameter, the second diameter being greater than the first diameter.

Abstract: A fracturing fluid including a mixture of an aqueous terpolymer composition including a terpolymer, an additive, and crosslinker. The terpolymer includes 2-acrylamido-2-methylpropanesulfonic acid, acrylamide, and acrylic acid monomer units, or a salt thereof. The additive includes a sugar alcohol or a derivative thereof, and the crosslinker includes a metal. The weight ratio of the metal to the terpolymer is in a range of 0.01 to 0.16, and a concentration of the additive is in a range of 0.001 wt. % to 10 wt. % of the fracturing fluid. 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 mitigates damage caused by substantial amounts of total dissolved solids or significant water hardness.

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 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 fracturing fluid including a base fluid including salt water, a polymer, a crosslinker, and a nanomaterial. The crosslinker may include a Zr crosslinker, a Ti crosslinker, an Al crosslinker, a borate crosslinker, or a combination thereof. The nanomaterial may include ZrO2 nanoparticles, TiO2 nanoparticles, CeO2 nanoparticles; Zr nanoparticles, Ti nanoparticles, Ce nanoparticles, metal-organic polyhedra including Zr, Ti, Ce, or a combination thereof; carbon nanotubes, carbon nanorods, nano graphene, nano graphene oxide; or any combination thereof. The viscosity and viscosity lifetime of fracturing fluids with both crosslinkers and nanomaterials are greater than the sum of the effects of crosslinkers and nanomaterials taken separately. Moreover, this synergistic effect offers significant, practical advantages, including the ability to use salt water rather than fresh water for fracturing fluids, the ability to reduce polymer loading to achieve a desired viscosity, and the ability to achieve better formation cleanup after the fracturing treatment.
