At Bit Inclination Assembly
The At Bit Inclination Assembly (ABIA) is the newest addition to Vector Magnetics' line of HDD tools. Available as part of a rental motor or bit sub, inclination at the bit can now be monitored in real-time - a first for the HDD industry.
Absolute inclination is transmitted from the bit-box via EM to the ParaTrack 2 probe positioned in its normal position in a non-magnetic drill collar. Drill-string inclination is monitored in RivCross software, where inclination at the bit can be compared to inclination at the probe, greatly assisting the surveyor in conditions with mixed substrates or when tight tolerances on inclination are required.
