Abstract
Hydraulic fracturing fluids and methods to hydraulically fracture a subterranean formation and oxidize organic material in the subterranean formation. The hydraulic fracturing fluid includes water, another fluid, and a surfactant. An inorganic oxidizer is included in the water.
Claims30
A method of hydraulic fracturing, comprising:
- providing a hydraulic fracturing fluid through a wellbore into a subterranean formation, the hydraulic fracturing fluid comprising water, a nonpolar fluid, and a surfactant, wherein the hydraulic fracturing fluid comprises an inorganic oxidizer in the water and a reactive gas that is an oxidizer in the nonpolar fluid, wherein the nonpolar fluid is at least 50 vol % of the hydraulic fracturing fluid, and wherein the water is less than 50 vol % of the hydraulic fracturing fluid, wherein the hydraulic fracturing fluid comprises an aqueous phase and a non-aqueous phase, wherein the aqueous phase comprises the water and is a continuous phase of the hydraulic fracturing fluid, and wherein the non-aqueous phase comprises the nonpolar fluid and is not a continuous phase of the hydraulic fracturing fluid;
- hydraulically fracturing the subterranean formation with the hydraulic fracturing fluid;
- and
- oxidizing organic material in the subterranean formation with the hydraulic fracturing fluid.
