The disclosed hydraulic fracturing fluid can include a liquid solvent, one or more surfactants, a proppant-forming compound, and one or more curing agents. When injected into a wellbore, the hydraulic fracturing fluid reacts to form proppant pillars in-situ under downhole conditions. The proppant pillars are capable of maintaining conductive fractures.

A hydraulic fracking aqueous fluid, including: water; one or more soluble calcium salts; a carbonate ion generating compound; and one or more soluble zinc salts. A method for fracking an underground formation using the hydraulic fracking fluid.

Proppant particulates like sand are commonly used in hydraulic fracturing operations to maintain one or more fractures in an opened state following the release of hydraulic pressure. Fracturing fluids and methods of hydraulic fracturing may also use proppant particulates composed of fluid coke material (also referred to as fluid coke proppant particulates). In some instances, the fluid coke proppant particulates are characterized by a bulk density of less than about 0.9 grams per cubic centimeter.

A method for enhanced depth penetration of energy into a formation may include mechanically stimulating proppant in proppant-containing fractures in the formation at a first frequency to induce mechanical stress in the proppant and directing electromagnetic radiation at a second frequency into the proppant-containing fractures of the formation while mechanically stimulating the proppant, wherein the first frequency and the second frequency are the same or different and wherein the proppant includes silica.

A method of repairing a well is provided. The method includes injecting a brine solution into the well, injecting carbon dioxide into the well, and reacting the brine solution in the reservoir rock with the carbon dioxide to form calcite such that calcite precipitates into the desired flow path between a cold well and a hot well to effectively repair short circuits within the EGS reservoir.

A method for controlling fluid loss into the pores of an underground formation during fracturing operations is provided. Nanoparticles are added to the fracturing fluid to plug the pore throats of pores in the underground formation. As a result, the fracturing fluid is inhibited from entering the pores. By minimizing fluid loss, higher fracturing fluid pressures are maintained, thereby resulting in more extensive fracture networks. Additionally, nanoparticles minimize the interaction between the fracturing fluid and the formation, especially in water sensitive formations. As a result, the nanoparticles help maintain the integrity and conductivity of the generated, propped fractures.

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.
