DTI's EH (Expanding Hanger) High Expansion Gauge Hanger Running Tool is a wireline tool specifically designed to run and set the DTI High Expansion Instrument Hanger into the well bore.
The Running Tool is a mechanical tool designed to store the energy required to expand and set the hanger. It comprises a stack of disc springs, contained within a cylinder body, which are held in a compressed condition. The stored spring energy is held by a locking mechanism and shear pin.
A DTI Installation Tool is used to compress the springs inside the EHRT before the EHRT is made up to the DTI Expanding Instrument Hanger. The complete assembly, including memory gauges, is run into the well until stopping. The wireline suddenly shock shears the activation pin to start the setting sequence. Light upward jarring fully sets the Expanding Instrument Hanger and releases the EHRT which is pulled out of hole.
The EH Running Tool is a purely mechanical alternative to explosive or electric type setting tools.
