Hydraulic setting tools
Used to run and set packers
The setting tools is assembled to the packer.
As the packer and setting tools are lowered
into the wellbore and reaches the desired
depth, a ball will drop from the top into
the string and pressure is applied to the
string. Hydraulic pressure acts on the
internal part of the setting tools, creating
the push/pull action to the piston of the
packer which is necessary to set the packer.
When the packer is fully set, pressure is
increased to the value of shear pins of
the setting tools catcher sub. After shearing
the pins, the pressure will release and the
Right-hand rotation disengages the setting
tool from the packer.
