Services and supplies offered by AEGIS Instruments and associated companies

AEGIS Instruments has been based in Botswana since early 1994.  AEGIS supplies a large range of established, field worthy geophysical equipment and accessories throughout sub-Saharan Africa. AEGIS also maintains a rental pool of equipment for clients to use, either to test prior to making a purchasing decision, or for completing a project as the work entailed does not warrant purchasing the equipment. AEGIS and its associated companies MGE Consulting and Current Exploration Solutions also offer specialised geophysical surveys such as:

  • High-resolution surface, borehole, VSP and in-mine seismic reflection surveys;
  • Surface and borehole TDEM surveys: shallow or deep surface surveys, borehole winches to 2500m, and standard or fluxgate measurements;
  • AMT or MT surveys and in-depth interpretations;
  • Wireline logging services to complement the above;
  • Airborne geophysical and satellite imagery processing and interpretation;
  • Core scanning using DMT’s CoreScan 3 unit, software for structural and mineralogical interpretation of the core, XRF analysis and physical property measurements;
  • Historical data review, evaluation and re-interpretation with close reference to available geological and geochemical information. The results can be presented in a geological software package such as Micromine.

The workshop aims to provide a simple but effective framework for using wireline logs in exploration and mining. What measurements are available. What can and cannot be achieved. What can go wrong. How to prepare. The workshop aims to be interactive and to engage with the participants to determine what their perception of borehole logging is and whether it is being used effectively. Multiple log examples will be presented. This is a practical discussion based on real life logging operations.
