MODEL “H” HYDRAULIC SETTING TOOL
The Model “H” Hydraulic Setting Assembly
(HST) is a hydraulic setting tool designed
for setting packers and plugs without
pipe manipulations. It is used to set
packers and plugs that are normally set
with a Model “E-4” Wireline Pressure
Setting Assembly (or similar wireline
setting equipment). The same adapter kit
that is used on wireline can be used with
the Model “H” HST.
The Model “H” HST and packer (or plug)
is run in on the tubing to the desired
setting depth and a ball is dropped to the
HST. Pressure is applied to close the fill
ports, which also opens the setting pistons
to pressure. As pressure is applied, force
is transmitted to the packer (or plug) to
set. Tubing tension can also be applied to
supplement the setting force generated by
the pressure applied.

The standard setting tool comes with
three pistons, but additional pistons can
be added to reduce setting pressure.
Special Features
> Large internal by-pass
> Tubing fills automatically as HST is run
in the hole
> Premature setting is prevented by
means of a shear screw in the cross
link sleeve
> Ported top sub permits circulation
through the HST
> Use existing wireline adapter kits
