terratec Geophysical Services offers surface geophysical and borehole logging services worldwide. The main objectives are the acquisition, compilation, processing, analysis and the interpretation of geophysical data. We execute these services for mineral exploration, ground water/ geothermal energy prospecting and geotechnical purposes. terratec Geophysical Services was founded in 1989 and consists of 35 geophysicists and geologists who are fluent in a great variety of languages, including English, German, French, Spanish, Russian and Arabic with bases in Germany, Austria, Mali, Namibia and Canada and representatives in Sweden and Finland. terratec Geophysical Services has comprehensive working experience in different countries and climates from Greenland to South Africa. Staff and geophysical systems have been optimized and adapted to harsh conditions in remote areas. terratec operates > 17 logging systems. Specialist down hole tools include optical and acoustic borehole scanners, spectral gamma, borehole deviation (MEMS and magnetic for open hole and gyroscopic within drill rod), induced polarisation surveys and flow meter surveys (fluid logging) from 0 to 2000 meters depth. Surface geophysics is represented by the principal methods of induced polarisation, both 2D and 3D with the in house development of the HIRIP method (high resolution induced polarisation), surface to hole and hole to hole IP, ground gravity, time and frequency domain EM, magnetics and radiometrics.
