ABSTRACT:
A modular perforating gun system for use in perforating a well. The system comprises a lower perforating gun module or section which may be supported in a variety of ways adjacent to a well formation to be perforated. The system further comprises at least one additional perforating gun module or section which is positioned above the lower perforating gun module. After firing, any number of the perforating gun modules may be individually retrieved from the wellbore without killing the well and subsequently replaced as necessary.
