GYR38 Gyroscopic Probe – Borehole Deviation Measurement

A gyroscopic probe (or gyroscope) is a sensor that measures the rotational velocity of an object around an axis. It allows determining the orientation and angular movements of an object in space. These sensors are used in many applications, ranging from smartphones to ship stabilization systems.

The GYR38 is a gyroscopic borehole deviation probe specifically designed for the demanding environments of drilling and mining operations.

This north-seeking device (for probe inclination values between 3° and 177° from vertical) accurately provides continuous trajectory data in non-vertical boreholes. A north search time of only 2 minutes and a 60-minute measurement time between corrections help maximize operational efficiency.

The GYR38 probe operates in wired mode via our proven eMindLogger acquisition unit. The borehole azimuth and inclination from the IMU are displayed in real time at the surface in our standard 6CH logging software.

Additionally, optional parameters such as natural gamma and/or a CCL (Casing Collar Locator) detector can be added to the base probe.
