Abstract
There is disclosed herein a method and apparatus for using rupture pins to selectively open jets on a jet perforating tool. Rupture pins inserted in jets within a jet perforating tool are configured to rupture at pre-designed thresholds, thereby opening the jet to begin a perforating job, or to circulate fluid through the tool. Also disclosed are systems and methods for holding the rupture pins within the tool prior to rupture.
