Abstract
Simulation of downhole transient pressure effects due to propellant stimulation of a formation provides information that may be utilized to select a type of perforating tool system and other components that contribute to effective stimulation of a formation. A well simulator pressure vessel comprises a perforating tool system that comprises a type of perforating gun assembly that includes one or more shaped charges. A propellant disk assembly adjacent to a sample formation is coupled to the perforating tool system. The propellant disk assembly comprises one or more components for securing the propellant. A transient pressure effect may be measured once the one or more shaped charges are detonated and the propellant is ignited or deflagrated. The measured transient pressure effects may be utilized to alter or change the one or more components of the perforating tool system prior to, during, or after stimulation of the sample formation.
