The At Bit Inclination Assembly reduces uncertainty by providing an inclination measurement directly at the bit, allowing for tight radius bores in unconsolidated or fractured formations where build and drop rates are otherwise difficult to predict.
- Steering feedback directly at the bit
- Low impact on operations
- Compatible with all common HDD pilot hole sizes

Inclination is transmitted from the ABIA bit-sub via electro-magnetic transmission to the ParaTrack2 Steering Tool positioned normally in a non-magnetic drill collar. At-bit inclination is monitored in RivCross software where inclination trends at the bit can be compared to inclination at the probe, improving the surveyor’s ability to react quickly in conditions with mixed substrates or when tight tolerances are involved.
Available as part of a rental motor or as a stand-alone bit sub, the ABIA is compact, minimizing the effect on directional control and wear on other equipment. The battery is good for thousands of shots and field-rechargeable. Survey time of ~30 seconds limits the cost on rig time.
