MWD/LWD Solutions and Innovations

Downhole Sensors


Highly sensitive, ruggedly designed downhole sensors and detectors for measure-while-drilling and logging-while-drilling applications.

Reuter-Stokes, a Baker Hughes business, provides downhole sensors and instrumentation to support your downhole operations. We provide scintillation detectors for gamma-ray and neutron detection and spectroscopy applications to confirm that you have the best data for your logging-while-drilling (LWD) operations. Our uniquely rugged design ensures the largest scintillation crystals can be used in operations while keeping sensitive equipment safe from damage in these extreme applications. More light from our design enables quick and accurate identification of formation characteristics.

Reuter-Stokes’ orientation modules ensure you stay on course. Each system is fully factory-calibrated in a state-of-the-art facility to verify that the equipment performs to specification at the drilling rig.

Reuter-Stokes equally invests in our production capability, having recently added 1,600 sq. ft of production capacity to deliver quality products on time.

Here are just a few ways Reuter-Stokes' downhole sensors can be used in your LWD and MWD operations: 

  • Gross counting gamma - Passive gamma measurement to determine formation boundaries.
  • Spectral gamma - Passive gamma measurement to determine the element emitting the gamma rays.
  • Density gamma - Active gamma measurement used to determine the density of the formation.
  • Neutron porosity - Active neutron measurement used to detect hydrogen in the formation.
  • Inclination - Measures angle from vertical using accelerometers and gyroscopes.
  • Azimuth - Measures compass heading of hole direction relative to the Earth’s magnetic pole using magnetometers.
