Tolteq Hellfire MWD Configuration

Our most advanced and reliable MWD configuration delivers next-generation performance in North America’s most demanding applications.


Built on our highly successful Tolteq™ measurement-while-drilling (MWD) platform, the Tolteq Hellfire MWD configuration was specifically designed for the harsh, vibration-prone, and high-temperature conditions typical of North America wellbores. With a name to match its aggressive performance in harsh conditions, our Hellfire MWD system delivers advanced, continuous measurements supported by cutting-edge telemetry speed and consistency in an extremely reliable and cost-effective package.

Hellfire MWD tools are available as a ready-to-deploy kit, combining the Tolteq NXT top-mount pulser, the new NXT directional module, SureMate™ centralizers, and the NXT GUIDE decoder. The Hellfire system leverages the latest top-mount pulser technology, which is engineered to perform in high-vibration environments while delivering exceptional pulse consistency and reliability even in extended-reach lateral applications. At 4 bits per second, we offer one of the fastest and most reliable data rates on the market, which is automatically decoded by the Hellfire’s ultra-intuitive and remote-operations-enabled surface system.

The Hellfire MWD configuration includes real-time pressure-while-drilling measurements, enabling access to advanced drilling optimization capability on every run. In addition, the Hellfire system can be configured to meet a wide variety of applications, including azimuthal gamma modules for more demanding reservoir navigation requirements.

With a reliability-driven design philosophy and continued development leveraging NOV’s world-class R&D facilities, directional drillers can be assured that Tolteq MWD products will remain the leading independently manufactured MWD solution in the market. All Tolteq tools are fully designed and manufactured in-house by NOV experts using the latest manufacturing techniques and design standards to avoid compatibility and interface issues.
