Abstract
To optimize the efficiency of a perforating tool system, downhole conditions may be simulated to determine the optimal configuration for the perforating tool system. A simulated wellbore is disposed in a simulated wellbore case and coupled to a formation sample. The simulated wellbore comprises the perforating tool system and one or more filler discs that consume a volume of the simulated wellbore. The filler discs are used to control the dynamic underbalance for a given simulation of a perforating tool system. One or more measurements associated with the perforating tool system along with one or more images may be generated after explosive charges of the perforating tool system are detonated. The perforating tool system may be modified based, at least in part, on the one or more measurements and the one or more images for the specific dynamic underbalance of the simulation.
