The Geotechnical Business-Focused Team (BFT) of the Western Federal Lands Highway Division (WFLHD) required a process for collecting data during geotechnical subsurface explorations that was easier and faster than the handwritten borehole logging (recording) system currently being used by WFLHD.
The focus was primarily on phasing out handwritten borehole logging and implementing a procedure for electronic borehole logging.
For depleted reservoirs, geological information is usually available from the original oil and gas exploration process (although both borehole logging and geophysical investigations tend to focus on the reservoir horizons and further data might need to be obtained on the overburden strata).
The probe is part of the SIROLOG suite of spectrometric borehole logging tools developed by CSIRO Exploration and Mining to evaluate the composition and quality of coal, ore and rock at mine sites.
Businesses taking part in the mission, which was led by WalesTrade International, included Glan Conwy-based Geovista which manufactures borehole logging and inspection camera systems.

He emphasizes fundamental principles and specifically avoids topics that require lengthy explanation, such as borehole logging and seismology.
Detailed borehole logging, supplemented by petrographic studies, demonstrates that at least three phases of copper-bearing potassic alteration are present.
