Laboratory Geoelectrics and Optoelectronics

The devices for geoelectric measurements include various tools such as a GeoTom, resistivity probes, non-polarizable probes and electrode cables of various lengths for surface and downhole application. A sandbox model (diameter and height 0.6 m) is employed for miniaturized geoelectric measurements. The optoelectronic laboratory provides a suitable development peripheral to create system solutions based on optical, electronical and mechanical components and thus to support the engineering work of the CGS. This includes the test of a fiber optic refractive index (RI) sensor as monitoring tool for fluid-gas interactions: calibration charts for various synthetic brine solutions and for the CO₂ pressure dependency.
