High sensitivity, excellent quality, downhole instrumentation
MWD/LWD Instrumentation by Reuter-Stokes
Reuter-Stokes provides instrumentation for your downhole operations. We provide neutron and gamma detection and spectroscopy to ensure you have the best data for you logging while drilling (MWD) operations. Our unique ruggedization design ensures largest crystals can be used in operations, while keeping sensitive equipment safe from damage in these extreme applications. More light from our design means faster and better identification of formation characteristics.
Reuter-Stokes’ measure while drilling (MWD) orientation module will ensure you stay on course. Each system is fully factory calibrated in a start of the art facility to ensure equipment is working to specification when it arrives at the drilling rig.
Reuter-Stokes invests equally in our production capability, recently adding ### sq. ft of production space, to ensure we have to capacity to deliver quality and reliable instrumentation on time, never leaving your rig waiting for proper LWD and MWD components.

Reuter-Stokes tailors every scintillation detector to your exact specifications. We provide a broad range of detector configurations, including virtually any crystal size, mounting and interface adaptations, as well as built-in radioactive check sources.
The assembly’s high-strength sapphire window, combined with a patented optical coupler, allows for maximum light output. Using the highest quality materials and a cutting-edge design, Reuter-Stokes is committed to engineering its sensors to meet strict customer specifications.
Delivering one of the industry’s highest sensitivities, our gamma sensors provide geologists and drilling contractors with the precise measurements required for accurate formation location and identification.
Our radial suspension system also contributes to greater detector sensitivity. By minimizing the radial space needed to isolate the crystal from vibration, larger crystals can be packaged inside the sensor housing. Higher sensitivity can help customers log faster or reduce the size of the detectors for more compact tools and thinner bed resolution. Thin wall titanium housings minimize gamma attenuation for better gamma radiation transmission at lower energies. These features allow customers to operate downhole confidently, even in the most severe conditions.
Our Helium-3 (He-3) filled detectors offer the optimal combination of high efficiency and sensitivity, with good gamma discrimination and excellent vibration response, all in the most compact package possible. This ensures reliable performances for LWD measurements without taking valuable space from other components on the drill bit assembly.
These detectors incorporate the operational experience gained from the design and manufacture of more than 67,000 units over 50 years by Reuter-Stokes. cWe developed proprietary He-3 purification techniques, gas mixtures, and manufacturing process controls to ensure precise matching of operating characteristics among large batches of detectors. This permits parallel operation of multiple detectors without need for separate power supplies or gain matching.
Since entering this market in 1956, we have continually evolved our design and manufacturing capabilities for high-quality, custom detectors. We have built detectors that range from 0.3” (7.62 mm) to 2.25” (57.15 mm) in diameter, and 0.5” (12.7 mm) to 12” (304.8 mm) in length, with fill pressures from 60 to 180 psia (0.4-1 MPa). We also optimize the gas mixtures using a variety of quenching gases to insure the right balance between sensitivity and operating voltage. Finally, we offer a wide array of electrical terminations and mechanical interfaces to suit virtually any downhole application.
With more than 30 years of experience, our portfolio of custom-designed MWD orientation modules provides unsurpassed accuracy, reliability, and configuration flexibility. Our most compact borehole survey technology is designed to fit into the smallest of tools by using a compact electronics package. The technology has undergone extensive thermal cycle and soak testing up to 185°C to ensure the unit’s performance is accurate, stable and reliable. Test data indicates at least a 3-fold reduction in total magnetic field spread and bias change over time. For our customers, this means an increase of 2X in both life and mean time between calibrations, which translates directly to lower cost of ownership.
GE Oil & Gas orientation modules are designed for efficient operation in a compact, rugged chassis. By providing accurate and stable survey measurements, with minimal downhole power consumption, the module has helped customers lower operational costs associated with downhole batteries, and enabled the horizontal drilling techniques required for unconventional resource development.
