1. A perforation gun system having an outer gun carrier, comprising:
- a top connector;
at least one stackable charge holder for centralizing a single shaped charge within the gun carrier;
a detonation cord connected to the top connector and to each stackable charge holder;
at least one bottom connector for terminating the detonation cord in the gun system; and
a detonator energetically coupled to the detonation cord,wherein each of the top connector, at least one stackable charge holder and at least one bottom connector comprise a rotation coupling for providing a selectable clocking rotation between each of the top connector, at least one stackable charge holder and at least one bottom connector.

Abstract
A perforation gun system is provided including combinations of components including a top connector, a self-centralizing charge holder system and a bottom connector that can double as a spacer. Any number of spacers can be used with any number of holders for any desired specific metric or imperial shot density, phase and length gun system. A perforation gun system kit and a method of assembling a perforation gun system are also provided.

16. A perforation gun system kit having component parts capable of being assembled within an outer gun carrier, the kit comprising a combination of:
-
a top connector; at least one stackable charge holder for centralizing a single shaped charge within the gun carrier; a detonation cord connectable to the top connector and to each stackable charge holder; at least one bottom connector adapted for terminating the detonation cord in the gun system; and a detonator energetically couplable to the detonation cord, wherein each of the top connector, at least one stackable charge holder and at least one bottom connector comprise a coupling having a plurality of rotational degrees of freedom for providing a selectable rotation between each of the top connector, at least one stackable charge holder and at least one bottom connector.

18. A stackable charge holder for a perforation gun system having an outer gun carrier, the charge holder comprising:
-
a charge receiving structure for receiving a single shaped charge; a plurality of projections for centralizing the shaped charge within the gun carrier; and at least one rotation coupling for providing a selectable clocking rotation between the charge holder and an adjacent component in the perforation gun system, wherein a pair of the plurality of projections is configured for capturing a detonation cord traversing the charge holder. - View Dependent Claims (19)
