Tie-Back Liner
Tie-back is a string to connect a liner back to well head. It is fairly common for oil and gas wells and they almost always run for geothermal with sometimes 2 on one well.
Tie-backs can be installed for both land or offshore wells. Depending on where the wellhead is, the liner can be tied back to rig floor (platform) or seabed.
