Hydraulic Pipe Severance Tool

Page last modified
June 30 2024

The HyPR™ HoleSaver is the world’s first hydraulic pipe recovery system providing a quick, safe & low cost means of recovering from stuck pipe situations whilst maximising hole recovery.

Unlike conventional methods, the HyPR HoleSaver is a pre-placed sub or subs within the BHA. The device can be turned into severance points by simply deploying the HyPR Smart Dart.


With no moving parts, the full strength HyPR Sub lies dormant in the string. When activated with the HyPR Smart Dart, the flow of ordinary mud is redirected, creating a high velocity radial jet of fluid to erode and cut the sub in just a few hours.

When compared to traditional methods the HyPR™ can reduce the time of recovery from weeks to several hours
