Value proposition

HMH's 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 a user-friendly automated interface, designed to reduce well cost and optimize rig efficiency.

During drilling operations, the top drive provides continuous torque and revolutions per minute (RPM) to the drill string unit. Due to varying geological conditions and drill bit frictions, the constant input from the top drive does not give a constant output on the drillbit, resulting in large fluctuations of torque and RPM down at the bottom hole assembly (BHA). This leads to torsional vibrations, also known as stick slip effect, negatively impacting drilling performance and equipment deterioration.
