Model PHT Permanent Hydraulic Set Packer
The Model PHT Permanent Hydraulic Set Packer is a single-trip, high performance permanent packer ideally used in high pressure, high temperature environment where maximum performance is required. The no-mandrel-movement feature controls the packer setting sequence, preventing tubing stretch during setting which is a common problem in most packers.
The PHT packer possesses its own hydraulic setting system that may be configured with dual pistons to significantly lower the required applied pressure to hydraulically set the packer. Upon setting, the upper and lower slips create a full circumferential double-grip on the casing, spreading the load evenly onto a large casing footprint. Double cone options are available for each side of the external slips for extra anchoring force.
Utilizing a multi-duro, multi-material sealing element stack, the PHT Packer is designed to endure up to 15,000 psi (103.4 MPa) differential pressures in some sizes with element options up to 400°F (203°C) service temperature.
Key Features & Benefits:
- Top of range, high performance packer designed for HPHT applications
- Designed and manufactured to conform to API 11D1 V0 specifications
- V0 Rating available in some sizes
- Superior multi-durometer, multi-material element package protected from extrusion by expandable metal back-up rings for higher performance
- 360° hardened, bi-directional slips maintain a reliable anchor to casing at high pressure differentials and applied loads
- Double cone option available to maximize anchoring force and casing anchoring footprint
- Double piston option to increase setting load or reduce setting pressure depending on specific well planning
- No mandrel movement during and after setting
- Packer may be field adjusted to achieve desired start-to-set pressure
- Components, including core of slips, retains metallic structure for easy milling
- All components rotationally and axially locked to prevent pre-set of packer when running in well
