{HEAD ~ The method} comprises the steps of: perforating a zone of the production interval by injecting a pressurized fluid through a hydrajetting tool into the subterranean formation, so as to form one or more perforation tunnels; and injecting a fracturing fluid into the one or more perforation tunnels so as to create at least one fracture along {TAIL ~ each} of the one or more perforation tunnels; wherein at least a portion of at least one of the pressurized fluid and the fracturing fluid comprises a viscoelastic surfactant fluid
