Technical Data Sheet
9 1/2" OnTrak II
Directional Sensor Vibration, Stick-Slip
35.1 ft (10.7 m)
For reservoir navigation applications, the OnTrak MPR sensors provide eight multi-depth resistivity measurements enabling optimum well placement. Two gamma ray detectors mounted on opposite sides of the tool provide an indication of approaching bed boundaries and can be used to provide an image of the wellbore. The annular pressure reading enables fast reaction to wellbore stability issues and monitoring of the dynamics behavior of the BHA (with stick-slip and vibrations) allows the optimization of drilling parameters and improvements in reliability. Service Benefits Real time Reservoir Navigation and accurate well placement Geological confirmation of bed boundaries with azimuthal gamma ray Fast two-way communication between surface and downhole saves time Optimum directional control due to sensors closer to the bit Fewer well control issues and improved reliability Fully modular system allows the complete integration of high end LWD services (SoundTrak™, LithoTrak™, CoPilot®, TesTrak™) ® Excellent log quality when used with AutoTrak G3.0 applications at high ROP High frequency phase resistivity measurements for superior vertical resolution and improved definition of thin beds and fluid contacts Low frequency attenuation resistivity measurements for increased depth of investigation gives better estimates of Rt with a greater immunity to environmental effects

INTEQ developed the 9 1/2" OnTrak™ II to be a fully integrated MWD/LWD tool, providing real time Directional, Gamma, MPR® resistivity, downhole pressure and vibration measurements from a single sub. The OnTrak tool has been uniquely designed to take into account all the challenges present in the most demanding rotary steerable applications. The OnTrak sensor sub works in conjunction with the AdvantageSM surface system to deliver optimal directional control, precise formation evaluation and data to enable reservoir navigation whilst drilling. This innovative design delivers increased reliability, reduces the number of connections and offers optimized sensor-to-bit distance in a compact BHA (bottom hole assembly). The tool combines an integrated sensor sub with a power and communications module supplying the following capabilities:
