Page last modified
July 4 2025
- Failures on Elastomeric Tubing Hanger Neck Seals on Wellhead systems are commonplace.
- Seals are either re energized or injected with special materials in the hope of repairing the failing seal.
- Failures cause hydrocarbon production to be reduced or stopped completely.
- Expensive workovers required to replace Tubing Hanger and Head Adapter with alternative designs.
- POS GRIP® “ Technology used to replace existing failing seals with a metal to metal sealing solution.
- Repair provides much better integrity and long term sealing capability against exiting elastomeric.
- Retrofit system providing metal sealing solution to leaking Tubing Hanger Neck Seals
- No need for expensive Full Workovers
- Production can be increased or restarted following retrofit.
- Seal can be tailored to suit specific requirements, i.e. no control lines, 1 or 2 control lines.
- Designed to suit specific pressure requirements.
