ABSTRACT:
A perforating gun includes a guide, a first charge unit, a second charge unit and a linkage. The first and second charge units are coupled to the guide. The second charge unit is capable of being in a collapsed position for passing the second charge unit through a tubing and is capable of being in an expanded position for detonating the second charge unit. The linkage is connected to the second charge unit to communicate an applied force to cause the second charge unit to move the second charge unit along the guide toward the first charge unit when the second charge unit is at least partially in the expanded position.
