CPT High Load Downhole Jack

TIW Casing Pulling Tool
The TIW Casing Pulling Tool (CPT) retrieves
casing in applications where the drilling rig or
work string does not have sufficient capacity
and can be used as a replacement for surface
casing jacking systems.

Furnished with a rotary shouldered pin
connection on the bottom allowing the use
of casing cutting and/or standard fishing tools
the CPT provides the pulling force required
to retrieve the casing. It can also be used to
dislodge other material from the casing or
wellbore.

The CPT downhole multi-stage hydraulic
actuator functions as a hydraulic jack. After
the casing has been located and tagged, a
hydraulically-set mechanically releasable
gripper anchors the CPT to the wall of the
larger ID casing above. Pressure is applied
to begin the upward movement of the fish.
After the stroke is completed, the anchors
are released. The power section can be reset
and the anchor re-engaged as many time as
required.


BENEFITS
  • Applies pulling loads at the fish not at the surface
