MH Soft Torque-Z: Reduce Drill Vibrations

The MH Soft Torque-Z system aims to reduce drilling costs and improve efficiency by mitigating drill bit oscillations and torsional vibrations. It incorporates Z-torque technology to continuously measure vibrations and regulate torque and speed accordingly. This eliminates stick-slip effects and allows for increased drilling speeds and payload. The simple automated system provides benefits like improved rates of penetration, fewer trips, safer connections, and smoother boreholes while requiring minimal changes to operator workflow.

MH Soft Torque-Z

Delivering smoother and faster drilling

MH Soft Torque-Z system mitigates oscillations on the drill bit and torsional vibrations, with
ease. The Soft Torque-Z effortlessly incorporates Shell’s proven Z-torque technology with an
user-friendly automated interface, designed to reduce well cost and optimize rig efficiency.

Product description Key features


During drilling operations, the top drive provides ¡ Our Soft Torque-Z system significantly reduces well
continuous torque and revolutions per minute (RPM) to cost and improves your drilling efficiency by:
the drill string unit. Due to varying geological conditions ¡ Increasing the operational window for weight on
and drill bit frictions, the constant input from the top drive bit (WOB) and speed during drilling, boosting
does not give a constant output on the drillbit, resulting in effective drilling time and rate of penetration (ROP)
large fluctuations of torque and RPM down at the bottom
¡ Minimizing the stops in circulation due to significantly
hole assembly (BHA). This leads to torsional vibrations,
reduced wear and premature failure of drill bits or
also known as stick slip effect, negatively impacting drilling
tools for measurement while drilling (MWD) tools, etc.
performance and equipment deterioration.
¡ Diminishing the number of over-torqued connections,
Our controller is based on Shell’s Z-torque technology, thereby reducing the need for manual tong
which continuously measures torsional vibrations in the operation; additionally, it eliminates the HSSE
drill hole and dynamically regulates around the torque and risk associated with utilizing manual tongs
speed set points accordingly. This mitigates the torque ¡ Improving the overall borehole quality,
vibrations in the drill string and reduces or even eliminates minimizing the risk for further
the stick-slip effect ¡ Reducing the number of side steps required in
a well drilled with Soft Torque-Z activated
Soft Torque-Z is fully operational immediately after
installation. Basic delivery is an operator screen.
Optionally, it can be integrated into your existing top drive
system. The simple user interface allows the operator to
continue drilling operation in a familiar matter.

Benefits
¡ Return of investment already after drilling one well
¡ Up to 70 % improved rate of penetration (ROP)
¡ Less unscheduled trips
¡ HSSE improvement due to less manual
handling of over torqued connections
¡ Simple user interface without changes in the operator
environment improves operational performance
¡ Improved borehole quality with smooth
walls and exactly positioned boreholes
MH Soft Torque-Z | Delivering smoother and faster drilling

Simple setup: the operator initially enters 2 parameters, and the system is operational instantly.
Daily use: Soft Torque-Z is simply activated or deactivated as required.

Logging data from MH Drillers Assist, Soft Torque-Z transition from Off to On
Examples shows actual Top Drive torque during drilling. In the beginning, Soft Torque Z is off and torsional vibrations
lead to fluctuating torque. When Soft Torque-Z is on, the torsional vibrations are effectively dampened.
