Description
The state-of-the-art 3D System MWD combines industry-standard measurements to provide an accurate, reliable, and cost-effective solution to MWD and LWD. With multiple telemetry speeds coupled with the latest in digital signal processing for noise immunity, data can be sent to the surface fast and efficiently, independent of drilling conditions.
The 3D MWD System is a platform that is able to support the most advanced technologies in the directional drilling industry. It serves as a foundation for Flashlight inclination and gamma at bit, Omega propagation resistivity, annular pressure while drilling and vibration monitoring while drilling tools.
The patented fast pulse telemetry allows resilient detection beyond what is possible with M-ary encoding. The piston pulser and directional module are shorter and lighter for better resilience to shock and vibration than legacy tools.
Applications
- Vertical, directional, and Horizontal drilling.
- Coil Tubing Drilling.
- Auto survey feature allows for continuous survey while drilling.

- Coal bed methane/coal seam gas.
- Mining/degasification.
Surface Equipment
- Wireless surface equipment option for easy setup.
- Touch screen display with depth input for standalone operations.
- Wired surface equipment for reliable connection.
- Software able to calculate minimum curvature surveys.
Features & Benefits
- Field Programmable.
- Operator configurable static and dynamic data.
- Programmable for extended battery life up to 400 circulating hours per battery pack.
- Fully retrievable. Reduce LIH exposure.
- Field-replaceable fin centraliser cutter.

Telemetry
The tool can be downlinked between fast pulse and M-ary.
M-ary Encoding is used for drilling deeper depths and longer battery life.
Fast Pulse produces a full-wave pulse signal for superior detection over M-ary encoding schemes. Higher-speed telemetry allows for higher log density and fast survey times.
