Zusammenfassung:A method of increasing a stimulated reservoir volume in a wellbore in a gas-containing formation includes the steps of mixing an exothermic reaction component to achieve a pre-selected solution pH, the exothermic reaction component is operable to react at a wellbore temperature to generate a pressure pulse, mixing the exothermic reaction component with a viscous fluid component operable to fracture the gas-containing formation to create fractures, and a proppant component, the proppant component carried to the fractures by the viscous fluid, the proppant component comprises a proppant operable to hold open the fractures, to form a fracturing fluid, injecting the fracturing fluid into the wellbore in the gas-containing formation to create fractures, and generating the pressure pulse when the exothermic reaction component reaches the wellbore temperature, the pressure pulse operable to create auxiliary fractures, wherein the auxiliary fractures create a fracture network, the fracture network increases the stimulated reservoir volume.
