Abstract
A wellbore perforating apparatus and method according to which a perforating gun and a sensor sub are run into a wellbore toward a downhole location at which the wellbore is to be perforated. Detonable components of the perforating gun are energized to perforate the wellbore at the downhole location. An acceleration of the perforating gun and a pressure and a temperature of the wellbore are detected using the sensor sub during a time interval encompassing the energization of the detonable components. The detected acceleration, pressure, and temperature are compared to benchmark energetic responses for both detonation and deflagration events. Based on this comparison, a decision can be made as to whether an incubation period is needed to allow a reaction of the detonable components to weaken before retrieving the perforating gun from the wellbore.
