Tie Back Packer
Tie Back Packer
Description & Application
The Tieback Packer is a single-grip, compression-set, liner-top isolation packer, typically run on drill pipe to repair a liner lap leak or for mono-bore liner-top completions. It is deployed using a mechanical setting tool in conjunction with a liner setting sleeve and PBR extension. Upon landing in the existing liner PBR extension, the integral seal stem at the bottom is inserted and pressure-tested through the work string. Additional slack-off weight actuates the collet lock nose and engages the upper packing element, creating a pressure-tight seal between the liner and casing annulus.
The straight slack-off weight setting mechanism eliminates the need for pipe rotation, hydraulic setting ports, or temporary plugging devices to set the packer.
Features And Advantages
- Full-Bore Single Mandrel – Provides an unrestricted internal diameter at the liner top.
- The elastomeric/metallic seal element is highly resistant to swab-off and mechanical damage during run-in.
- Seal integrity on the seal stem ensures high-pressure performance even after repeated hot stabbing into the liner PBR extension.
- Slips offer maximum hold-down and lift capabilities without compromising the casing or packer mandrel.
