TIGOR
Inspired from the technology used by petroleum directional drilling, the Tigor is an instrumented drill rod including the sensors for measuring the deviation, onboard electronics and batteries.
TIGOR
The TIGOR system comes as a non-magnetic rod about 1 meter long depending on the version and is also available in single jet and double jet.
TIGOR single jet: In diameter 89, it includes a central conduit that allows the drilling fluid or high-pressure grout to pass through the TIGOR to the jet.
TIGOR double jet: In diameter 127 mm, it includes a central conduit that allows the drilling fluid or high-pressure grout to pass through the TIGOR to the jet, and a lateral conduit for the passage of air to the second jet.
The TIGOR always integrates the sensors in all its versions, to measure:
- inclinations in two perpendicular plans,
- azimuth in relation to magnetic north.
