Abstract
A method for redressing a setting tool for actuating a plug in a subterranean wellbore includes recovering the setting tool from the wellbore, the setting tool including a housing with a throughbore therein, a piston arranged for axial movement within the throughbore, a combustible element, and an exhaust diffuser configured to redirect a flow of combustion products generated in response to ignition of the combustible element, removing the piston from the throughbore of the housing, removing the exhaust diffuser from the housing, cleaning the piston and the housing, and reinstalling the piston into the housing of the setting tool with at least one of the exhaust diffuser and a replacement exhaust diffuser for subsequent use of the setting tool in a wellbore.
