Abstract
A method comprises: a. determining a configuration of a gun string, b. determining, by a computer, a pressure transient at a location in a wellbore, c. comparing the one or more pressures with the one or more pressure thresholds at the location, and d. perforating the wellbore with the gun string using the determined configuration of the gun string when the one or more pressures meet the one or more pressure thresholds at the location. The location in the wellbore has one or more pressure thresholds, and the pressure transient comprises one or more pressures.
