MHT Modular Hydraulic Setting Tool
108 © 2005-2010 Weatherford. All rights reserved.
Weatherford’s MHT modular hydraulic setting tool sets the UltraPak
permanent packer and BlackCat retrievable sealbore packer on tubing
or drillpipe in many completion applications. With a slim OD and stackable
setting pistons, the MHT can set packers with ODs of 5 in. (127 mm) and
larger by changing the adapter kit. The MHT enables the annulus to be
pressure tested after the packer is set and is released from the packer by
rotation to the right.
The robust MHT construction can withstand forces up to 150,000 lb
(68,039 kg). It uses elastomers suitable for temperatures up to 400°F
(204°C).
Applications
• Setting of all sealbore packers
• Highly deviated and horizontal wells
• Heavy mud systems
• High bottomhole temperature applications
Features, Advantages and Benefits
• The MHT enables the well to be circulated before the packer is set,
preventing debris accumulation.
• The heavy-duty MHT construction enables the packer assembly to be
pushed into place in high-angle and horizontal wells, enabling the packer
to be set where wireline deployment is difficult or impractical.
• The MHT design enables packers to be set with pressure only or with
pressure and tension for deployment in shallow and deep applications.
• The stackable piston arrangement enables the setting pressure to be
varied to the output force of the well.
• Large fluid passages prevent the MHT from plugging in heavy mud
systems.
• The packer seal enables the annulus to be pressure tested, ensuring
packer integrity before the MHT is released.
• After the packer is set, the ball seat can be sheared to drain the work
string during retrieval, saving rig time.
Options
• A kit for temperatures above 400°F (204°C) is available.
