HYDRAULIC SETTING TOOL
WCTL-07,
WC /MR/DOC 52/I 02/ R01
The Hydraulically setting tool is used to set Permanent Packers, Retrievable Hydraulic
Seal Bore Packers and Wireline set Retrievable & Permanent Bridge plugs. Packer or
Bridge plugs run with the wire line adapter kits, attached to the Hydraulic setting tool on the
drill pipe and lowered to setting depth. The Tubing fills automatically as it is run in, though
a ported top sub in the setting assembly. The ports also permit circulation at any time. A 1
7/16” Ball is pumped down to seat in the hydraulic setting tool. Approximately 1500 psi is
applied to set the packer/bridge plug slips. Following which the pressure is increased and /
or tension applied in steps of 100-200 psi to fully set the packer and to shear the release
stud of the Wire line Adapter Kit. The Hydraulic Setting Tool along with wire line adapter kit
can then be retrieved leaving the packer set in hole.
FEATURES/BENEFITS
1. The feature of the Model ‘WC-HST’ Hydraulic Setting Tool is that it permits setting on
Tubing equipment which could previously be set only with wire line setting tools. This is
particularly advantageous in high angle or deviated wells, where wire line setting is
extremely difficult.
2. Premature setting is prevented by means of a shear screw in the cross link sleeve.
3. The Tubing fills automatically as it is run in the hole through a ported top sub in the
setting tool. These ports also permit circulation through the Setting tool at any time.
OPERATION
The adapter kit is made up onto the packer/bridge plug, and the setting tool is made up
onto the adapter kit. The assembled tools are then run in, on the Tubing, to the desired
setting depth.
A 1 7/16” dia ball is pumped down the Tubing to its seat in the support sleeve of the
setting tool. 1360 PSI pressure is applied to shear the shear screws in the support sleeve.
The support sleeve, in its sheared position, closes off the top sub ports, diverting all
pressure to the pistons. Pressure is applied directly to the upper piston and indirectly,
through the hollow piston rod, to the lower piston. (Pressure applied to the upper piston is
also transmitted, as force to the lower piston through the solid portion of the piston rod.)

As the piston moves downwards, the cross link which connects the lower piston rod and
the cross link sleeve, forces the cross link sleeve downward. While the setting mandrel
which is attached to the lower end of the packer body by means of the adapter kit remains
stationary, the cross link sleeve forces the adapter sleeve of the adapter kit and the upper
end of the packer body downward. In this manner, a squeeze action is applied to the
packer, forcing the slips and the packing element to set and pack off.
Approximately 1500 PSI pressure is required to set the upper slips. After the top slips are
set the packer setting and release can be completed either by applying tension, by pump
pressure or by any combination of the two. See table given below for the various
combination of pump pressure and the Tubing strain required to part a 1”, 55,000 lbs
release stud for size 20 setting tool.

The adapter kit and the setting tool may then be removed from the well.
As the upper piston moves downward to the cylinder connector, ports in the lower end of
the upper cylinder are uncovered, allowing the fluid in the Tubing to unload as the setting
tool is retrieved.
ASSEMBLY INSTRUCTIONS
Care should be taken after each run to inspect the O-rings and replace the shear screws in
the setting tool.
