Perforating gun assembly and method for controlling wellbore pressure regimes during perforating

Abstract

A perforating gun assembly (100) for use in a wellbore. The perforating gun assembly includes a carrier gun body (102) and a charge holder (132) disposed within the carrier gun body (102). A plurality of shaped charges (106-126) are supported within the carrier gun body (102). A secondary pressure generator is operably associated with at least one of the shaped charges. The secondary pressure generator optimizes the wellbore pressure regime immediately after detonation of the shaped charges by controlling the dynamic underbalance created by the empty gun chambers to prevent excessive dynamic underbalance which may detrimentally effect the perforating operation.
