Abstract: A perforating gun string is configured to perforate a casing of a well, and the perforating gun string includes a latch mechanism configured to engage with the casing, one or more perforating guns connected with a cable to the latch mechanism, and a global cable that releasably holds together the latch mechanism and the one or more individual perforating guns. The perforating gun string may also comprise a spreading mechanism configured to move away from the latch mechanism and to spread the one or more individual perforating guns away from the latch mechanism.
