The gyroscopic probe (SixGyro) provides borehole deviation measurements regardless of their horizontal/vertical inclination and at any depth.
Centralizers are supplied to enable measurement of any borehole, regardless of diameter.
Measurements can be made in bare or cased boreholes or metal drill pipes (the probe is not susceptible to magnetic interference).
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 manageable by a solo operator.
The measurement step is operator-defined. The measurement process is fast (approximately 15 minutes for a 30-meter borehole in 1-meter 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.
