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.
