He emphasizes fundamental principles and specifically avoids topics that require lengthy explanation, such as borehole logging and seismology.
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.
