Measurement While Drilling

Popular in Oil & Gas exploration applications, the Measurement While Drilling (MWD) technique uses a measurement module located behind the drill head in the string of a downhole tool. The tool’s control system measures variables such as angle, vibration, and drilling speed.  The “pulser” unit sends the collected information back to the surface, across several thousand meters, through pulses in the drill mud (MPT – Mud Pulse Telemetry).  The pulses are generated by the actuator system that is driven by maxon’s Heavy Duty brushless servo motor assembly.  

Downhole Applications:

Additional downhole applications serviced by downhole & MWD motors such as maxon's heavy duty brushless servo motors include:

  • Wireline Tools
  • Rotary Steerable Systems (RSS)
  • Downhole Power Generation
  • Pipe Cutters
  • Logging While Drilling (LWD)
  • Valve Control.

The benefits of maxon’s Heavy Duty brushless Servo Motors & Gearmotors include:

  • Operating temperatures (-55°C… 200°C)
  • Withstands high shock loads and vibrations: 1000G / 25 grms
  • Operates at high pressure (up to 1,700 bar)
  • Highly reliable, even in harsh environments
  • Motors can run in air or fully submerged in oil
  • Motors can operate with optional high-temperature hall effect sensors or in sensorless operation with electrical motor controllers
