GSP II Liner Hanger
Designed for deviated and horizontal holes. Available in both mechanical and hydraulic options.
GSP II Hydraulic Set Liner Hanger
Designed for deviated and horizontal holes, the GSP II hydraulic-set liner hanger contains slips that are fully recessed into a special profile at the rotating body. This ensures trouble-free installation and uniform load distribution in the setting section. In set and non-set state, the GSP II liner hanger allows a very high bypass, ensuring a high flow rate with low pressure loss.
Hydraulic liner hanger design features
- All hydraulic seals remain stationary during rotation of the liner
- Improved seal stack in the hydraulic cylinder; HP/HT seals
GSP II Mechanical Liner Hanger
Designed for vertical and slightly deviated holes where rotational string manipulation is possible, the GSP II mechanical set liner hanger contains fully recessed slips, ensuring trouble-free installation and uniform load distribution in the setting section. The GSP II mechanical liner hanger utilizes a solid one-piece body that is not compromised by a hydraulic cylinder or any ports. Thus, allowing the liner hanger to have an overall enhanced performance rating that matches or exceeds the customer’s casing mechanical properties. In addition, the GSP II mechanical liner hanger allows a very high bypass area, ensuring a high flow rate with low pressure loss.
Mechanical liner hanger design features
- Enhanced overall performance ratings due to no need for hydraulic cylinder or hydraulic seals
- Standard right-hand mechanical set and release with left-hand option available upon request
