Claim Text:
1. A method of increasing a stimulated reservoir volume in a wellbore in a gas-containing formation, the method comprising the steps of: mixing an exothermic reaction component in an aqueous solution to achieve a pre-selected solution pH, wherein the exothermic reaction component is operable to react at a pre-selected wellbore temperature to generate a pressure pulse; mixing the aqueous solution with a viscous fluid component to form a fracturing fluid, the viscous fluid component operable to fracture the gas-containing formation to create fractures, and the fracturing fluid further comprising a proppant component, the proppant component carried to the fractures by the viscous fluid component, the proppant component comprises a proppant, the proppant operable to hold open the fractures; injecting the fracturing fluid into the wellbore in the gas-containing formation to create fractures; and after injecting the fracturing fluid into the wellbore, generating the pressure pulse with an unreacted amount of exothermic reaction component in situ, the unreacted amount of exothermic reaction component in situ sufficient for the pressure pulse to be between about 500 psi and about 50,000 psi, when the exothermic reaction component reaches the pre-selected wellbore temperature, such that the pressure pulse is operable to create auxiliary fractures by released pressure without the viscous fluid component and the proppant component, wherein the auxiliary fractures create a fracture network, wherein the fracture network increases the stimulated reservoir volume.
