ABSTRACT:
An improved downhole explosive charge carrier is disclosed. The invention uses a unique staggered charge pattern and a mounting configuration which allows the use of a straight, axially-located detonator in order to achieve a greater number of shots per unit length over conventional carriers. The invention also reduces the interference caused by the detonator and the closeness of the shots and thereby increases the performance of the individual charges, allowing smaller charges to be used to achieve the same perforation size.
