Tieback Packer

Patented sealing technology helps keep packer in position

Hold-down slips and our bi-directional seal-boosting technology keep the packer in position when pressured from below.

Application          

  • Second-run option for liner tops that do not have pressure integrity        
  • Used in combination with a tieback seal stem to isolate an existing liner top           

Deployment

The tieback packer is deployed using the A1 liner running tool with packer setting collet. The tieback is set by releasing the A1 running tool and then positioning the packer-setting collet on top of the tieback packer and using drill pipe weight to set down and energize the packer seal and hold-down slips.
