Abstract: A method for hydraulic fracturing of a subterranean formation includes injecting an oil-based fracturing fluid into the subterranean formation through a well. The method also includes injecting a second fracturing fluid, for example a water-based fracturing fluid, into the subterranean formation through the well after completion of the injection of the oil-based fracturing fluid.

Abstract: Methods for producing proppants with a fluorinated polyurethane proppant coating are provided. The methods include coating the proppant particles with a strengthening agent, a strengthening agent, and a resin to produce proppants with fluorinated polyurethane proppant coating. Additionally, a proppant comprising a proppant particle and a fluorinated polyurethane proppant coating is provided. The fluorinated polyurethane proppant coating includes a strengthening agent, a strengthening agent, and a resin. The fluorinated polyurethane proppant coating coats the proppant particle. Additionally, a method for increasing a rate of hydrocarbon production from a subsurface formation through the use of the proppants is provided.

Abstract: Unconventional hydrocarbon source rock reservoirs can contain the organic material kerogen, intertwined with the rock matrix. The kerogen can alter the tensile strength of the rock and contribute to higher fracture energy needs. To degrade kerogen and other organic materials, oxidizing gasses are dissolved in carbon dioxide (CO2) which is then used as part of a fracturing fluid. The oxidizing gasses can be dissolved directly in the CO2 or generated in situ using precursors.

Abstract: Techniques for treating a hydrocarbon reservoir include delivering a composition to the hydrocarbon reservoir. The composition includes at least one acid, and liquid or supercritical carbon dioxide (CO2). The method further includes exposing the delivered composition to water to activate the composition; and treating a rock formation of the hydrocarbon reservoir with the activated composition.

Abstract: A method and hydraulic fracturing fluid that is a viscoelastic surfactant (VES) fracturing fluid having a surfactant and an inorganic oxidizer salt for hydraulic fracturing of a geological formation. The VES fracturing fluid is provided through a wellbore into the geological formation to hydraulically fracture the geological formation to form hydraulic fractures in the geological formation. The method includes oxidizing organic material in the hydraulic fractures with the VES fracturing fluid.
