Tie-back Packer

 

The Tie-Back Packer is a liner top packer that is most frequently run on drill pipe to repair a liner lap leak or for a monobore liner top completion, using a mechanical setting tool and a liner setting sleeve. Upon running into the existing liner polished bore extension, the integral seal stem at the bottom is inserted until seated and pressure tested down the work string. Additional slack off weight trips the collet lock nose and actuates the upper annular seal element, forming a pressure tight seal between the annulus of the casing and the liner.

 

The seal and slips used on the Tie-Back Packer is ideal for “Monobore” type applications, while the straight slack off weight setting mechanism eliminates pipe rotation, hydraulic setting ports and/or temporary plugging devices to set the packer.

 

Features and Benefits

 

Full Bore single mandrel provides an unrestricted ID to the liner top once in place.

Innovative patented seal offers unsurpassed pressure and temperature ratings and rugged dependability. The bonded elastomer/metal seal element is highly resistant to swab-off and mechanical damage while running in the hole.

Proprietary seals on the seal stem ensure high-pressure integrity even after repeated hot stabling into the liner polished bore extension. Due to its rugged design, the Seal is less susceptible to damage while stabbing and un-stabling under pressure versus the conventional V-type packing.

Patented Dual-Set Slips provide maximum bold down and up capabilities without damaging casing or packer mandrel.

Useful as a liner top packer when running scab or tieback liners to surface.

Collet lock nose feature prevents pre-setting while running in the hole.

Positive set is held by internal body lock ring.

Withstands high pressures and temperatures.

Ideal for Monobore type liner top completions.

Unique dual slip design eliminates tubing forces from being transferred into the packer element.
