Product summary

The H-4 Perforating System is Hunting’s plug-and-play, self-orienting perforating gun which integrates ControlFire® Recon switch technology directly into the charge tube assembly.

H-4 eliminates costly eccentric weight bars and lock collars needed for conventional gravity-driven orientation. The patented H-4 tandem subs allow automatic rotation of the charge tube assembly for industry leading perforating accuracy.

The integrated ControlFire Recon switch allows automated firing at depth and for the detonator of the perforating gun to be checked downhole with ControlFire Software.

In addition to advanced switch technology, the H-4 Perforating System utilizes Hunting’s patented modular detonator to eliminate all wiring in the field. The RF Safe system is fully assembled at Hunting’s manufacturing center to ensure the highest quality and reliability.
