Viscoelastic-Surfactant Fracturing Fluids Having Oxidizer

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.

What is claimed is: 
     
         1 . A method of applying a reactive viscoelastic surfactant (VES) based fluid, comprising:
 providing the reactive VES-based fluid comprising a surfactant and an inorganic oxidizer salt through a wellbore into a subterranean formation, wherein concentration of the inorganic oxidizer salt in the reactive VES-based fluid is in a range of 3 wt % to 20 wt %; and oxidizing organic material in the subterranean formation with the reactive VES-based fluid, wherein oxidizing the organic material comprises degrading a filter cake with the reactive VES-based fluid during drilling of the wellbore, wherein the wellbore comprises an open hole wellbore.   
     
     
         2 . A method of applying a reactive viscoelastic surfactant (VES) based fluid, comprising:
 providing the reactive VES-based fluid comprising a surfactant and an inorganic oxidizer salt through a wellbore into a subterranean formation, wherein concentration of the inorganic oxidizer salt in the reactive VES-based fluid is in a range of 1 wt % to 20 wt %; and oxidizing organic material in the subterranean formation with the reactive VES-based fluid, wherein a filter cake comprises the organic material, and wherein oxidizing the organic material comprises degrading the filter cake with the reactive VES-based fluid, and wherein the wellbore comprises an open hole wellbore.
