GEOTECH S.A. performs a wide range of borehole logging techniques for multiple purposes such as hydrogeological, geothermal, mineral and geotechnical investigations.

Wireline equipment used and logging technology applied by GEOTECH S.A. are developed and produced by Robertson Geologging Ltd- Great Britain.
