Tensor Pro MWD
Tensor Rro MWD is an ultra-high temperature MWD system compatible with Tensor standards, which is mainly used to measure such downhole parameters as well deflection, azimuth, gravity tool surface, magnetic tool surface, gravity sum, magnetic field sum, temperature, gamma (optional), and azimuth gamma (optional).It is suitable for high temperature wells of unconventional oil and gas exploration and development. Tensor Pro system adopts a modular design to accurately measure the well deflection and azimuth, and provide real-time vibration and impact data, which can be transported in an easy and efficient manner, and can be assembled on the drilling site.

Product Features 

  • Suitable for high temperature, high pressure, and ultra-deep wells 
  • Optimized decoding performance for deep and ultra-deep well conditions 
  • Flexible interface:QDT pulser,Top mounted pulser 
  • High-precision orientation Modular to ensure precise trajectory Integrated dynamic directional survey to reduce pump stop time during directional survey Meticulously optimized process and design for high reliability
