High Pressure Hydraulic Release Tool
The High Pressure Hydraulic Setting/Release Tool (HRT-HP) has the same release features as the Standard HRT. The HRT-HP can also set the hanger’s seals and slips without the aid of a HSN.

Hydraulic Release Tool
A Hydraulic Release Tool (HRT) is a tool that relies on pins versus slips to secure and hydraulically release downhole assembly. The HRT can be functioned with compressive, neutral, or tensile loads.

Hydraulic Setting Nose
A Hydraulic Setting Nose (HSN) is a tool that is run in conjunction with the HRT. The HRT combined with the HSN can now set the hanger’s seals and slips before releasing it.
