Abstract

Shaped charges used in wellbore perforating operations may be tested using a stressed rock perforating-charge testing system. The system includes a shaped charge testing chamber. The shaped charge testing chamber may include a loading and ejection piston and a core sample chamber. The core sample chamber is in mechanical communication with the loading and ejection piston and is sized to receive a core sample. The shaped charge testing chamber also includes a core sample stress applicator to apply stress to the core sample. Further, the system includes an ejection mechanism adjacent to the shaped charge testing chamber to provide an ejecting force on the loading and ejection piston.
