Hollow Carrier

Gun perforating systems

Hollow carrier guns are pressure-tight steel tubes in which the shaped charges are positioned. For gun ODs of 2 7/8 in and larger, hollow carrier guns perform better than exposed guns because they use larger charges with optimized phasing and increased shot density. Hollow carrier guns are also used when debris is unacceptable and in hostile conditions that preclude using exposed guns.

To provide maximum perforator performance, our hollow carrier guns are designed as systems, comprising carriers, charges, detonating cords, and boosters. All components are manufactured to rigorous QA/QC standards and system performance verified through API RP 19B Section 1 test data. Gun systems are customized by optimizing their configuration to the wellbore environment and reservoir conditions with the SPAN Rock rock-based penetration model.
