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: Described is a polymer-based well tracer. The polymer-based well tracer is a fluoropolymer having a fluorinated group. The fluoropolymer may be formed into a particle, a coating for proppant particulates, or encapsulated in a polymeric resin. Upon degradation or hydrolysis of the fluoropolymer, the fluorinated group having a fluorinated compound is released within the well.

Abstract: This disclosure relates to methods of hydraulic fracturing that may include passing a fracturing fluid through a wellbore into a subterranean formation, wherein the fracturing fluid comprises a flowback enhancer composition in an amount of from 0.10 gallon per 1000 gallons of fluid (gpt) to 10 gpt based on the total volume of fracturing fluid, hydraulically fracturing the subterranean formation with the fracturing fluid, at least partially separating the fracturing fluid from the hydrocarbons to yield a recovered fracturing fluid. The flowback enhancer composition can include a solvent mixture comprising an aqueous solution, at least one unsaturated ester, and at least one alcohol; a surfactant mixture comprising at least one secondary alcohol ethoxylate and at least one castor oil ethoxylate; and one or more particles having a widest length of from 1 nanometer to 200 nanometers.

Abstract: A method of stimulating petroleum production includes introducing a fracturing fluid into a petroleum bearing carbonate formation, thereby creating at least one fracture to stimulate the petroleum production. The fracturing fluid is introduced into the petroleum bearing carbonate formation at a pressure above the breakdown pressure of the formation. The fracturing fluid includes a plurality of proppants where from 1 to 50 wt.% of the plurality of proppants includes micro proppants having a particle size ranging from 0.5 to 150 µm, and from 50 to 99 wt.% of the plurality of proppants includes macro proppants having a particle size greater than 100 mesh.

Abstract: Producing proppants with nanoparticle proppant coatings includes reacting nanoparticles with at least one of an alkoxysilane solution or a halosilane solution to form functionalized nanoparticles and coating proppant particles with unfunctionalized organic resin, a strengthening agent, and the functionalized nanoparticles to produce the nanoparticle coated proppant. The functionalized nanoparticles include nanoparticles having at least one attached omniphobic moiety including at least a fluoroalkyl-containing group including 1H, 1H, 2H, 2H-perfluorooctylsilane. The strengthening agent comprises at least one of carbon nanotubes, silica, alumina, mica, nanoclay, graphene, boron nitride nanotubes, vanadium pentoxide, zinc oxide, calcium carbonate, or zirconium oxide. Additionally, increasing a rate of hydrocarbon production from a subsurface formation through the use of the nanoparticle coated proppant includes producing a first rate of production of hydrocarbons from the subsurface formation, introducing a hydraulic fracturing fluid into the subsurface formation, and increasing hydrocarbon production by producing a second rate of production of hydrocarbons.

Abstract: A method for treating kerogen in a subterranean zone which includes the use of supercritical carbon dioxide or emulsions of liquid carbon dioxide and an aqueous fluid. The carbon dioxide or emulsions can further include oxidizers. The oxidizers can include inorganic oxidizers or organic oxidizers, for example an oxidizer including an organic cation and an oxidizing anion. Additional additives such as polymers, crosslinkers, clay inhibitors, scale inhibitors and corrosion inhibitors can further enhance the efficiency of the kerogen-treating carbon dioxide or emulsion.
