The TORNADO101 positive mud pulse MWD tool was developed by Pioneer Petrotech in order to address the needs of customers engaged in horizontal and directional drilling. It provides the following survey/directional measurements: inclination, azimuth, dip angle, high-side/magnetic tool face, earth gravity and magnetic field.
Other measurements; gamma ray and PVT (pressure, vibration, temperature), come in compact modules that can be added or subtracted from the tool as needed.
TORNADO’s unique down-hole coding and surface detection methods ensure the integrity of the real-time data from loss and disruption. A downhole vibration detection circuit provides real time data to the surface, visually displaying vibration levels for the operator, so they can change drilling parameters to protect the MWD tool. Also the overcurrent monitor will shut the pulser down if any overcurrent conditions are detected.

The retrievable and reseatable MWD tool can be operated over a wide flow rate range in collar sizes from 3-¾” (95.2-mm) outside diameter (OD) to 9-½” (241.3-mm) OD. If operations require, the tool can be retrieved and replaced by wireline due to its small diameter, allowing for cost-effective tool replacement.
The robust and ultra-compact design of the Driller Display Unit makes for easy placement on the drill floor. The transflective display screen and LED backlighting provide excellent viewability under all ambient light conditions.
The powerful and easy to use surface software provides MWD tool configuration, tests, diagnosis and data management. Digital signal processing in the software ensures that pulse detection is efficient over a wide range of drilling conditions.
