Technical Data Sheet Category Catalog

 

The Motorhead Assembly (MHA) is a compact, multi-use coiled tubing service tool used in drilling, milling and other workover operations. The tool features a dual circulation sub, ball actuated disconnect and a dual flapper style back pressure valve assembly.


The dual circulation sub gives the operator two methods to re-establish circulation from the drill string to the annulus; ball actuation or by means of a rupture disc.


The MHA ball disconnect provides a means of disconnecting the work string from the bottomhole assembly in the event the bottomhole assembly becomes stuck. Once the disconnect is actuated, the remaining ‘fish’ left in the well has an exposed “GS” profile for ease of reconnection with a subsequent recovery string.


The dual flapper back pressure valve prevents inflow from the well to the tubing. This feature ensures that during an unlikely event of surface pressure containment loss, well fluids are prevented from escaping from the well through the work string.
