SixGyro

The gyroscopic probe enables precise measurement of borehole deviation at any depth, independent of whether the borehole is vertical, inclined or horizontal. Its performance is unaffected by borehole orientation.

Centralising devices are provided to allow measurements to be carried out in boreholes of any diameter, ensuring reliable positioning of the probe during surveys.

Measurements can be performed in open or cased boreholes, as well as inside metallic drill rods. As the technology is not sensitive to magnetic disturbances, data quality remains unaffected by surrounding metal.

SixGyro: drilling deviation measurement

The small dimensions of the probe (22 mm diameter, 700 mm long and approx. 4 kg in weight) make it easily handleable by a solo operator.

The measurement step is operator-defined. The measurement process is fast (approximately 15 minutes for a 30-metre borehole in 1-metre steps).

As with most deviation systems, the azimuth start point must be measured by other means (topographically, GPS, etc.) and entered into the system.

Device accuracy (supplier data): 0.1° in inclination (0.2%); 0.5° in azimuth (0.9%).

Ultimate measurement accuracy depends on the accuracy of the device, the accuracy with which the azimuth start point has been measured, and the positioning of the probe within the borehole.
