Abstract
A method for stimulating a well includes mixing at least one thermochemical with fracturing fluid to create a fracturing fluid mixture, injecting the fracturing fluid mixture into the well, creating an exothermic reaction with the fracturing fluid mixture, generating a pressure pulse in the well from the exothermic reaction, and fracturing a formation around the well with pressure from the pressure pulse and a hydraulic pressure source.
