Model HC-D Tie Back Seal Nipple with Packer
Features
1. Run with casing or casing plus drill pipe. Used for the tie-back of a liner string to surface or to any position above the liner top. The packer is set after cementation.
2. Permanent pack-off is achieved after the packer is weight set.
3. Both the packer elements and groups of V-rings provide 5,000 psi sealing capacity.
4. Once the packer is set, the hold-down slips and the internal locking mechanism hold the packer tight. Neither picking up nor slacking off the drill string can retrieve the packe.
