Equipment for Geophysical Survey Measurements

Special attention is given to the quality of the equipment (machine fleet), whose reliability ensures the accuracy of the field data, a fundamental requirement for generating high-quality models. The company relies on internationally recognized manufacturers such as Guidelinegeo, Geometrics, Geotomographie, Lennartz, and IDS.

SEISMIC REFRACTION, REFLECTION AND MASW SURVEYS
