In the laboratory for fluid physics, various devices are used to determine the properties of geothermal fluids: density, viscosity, electrical conductivity, thermal conductivity, heat capacity, sonic velocity.

The lab is a facility maintained by research cluster "Temperature field of the Earth" of section 4.8. The lab produces data that are part of projects related to the analysis of the Earth temperature field. Thermal conductivity and thermal diffusivity of dry and saturated rocks are measured under ambient laboratory conditions using the optical scanning technology (Thermal conductivity scanner, TCS).

A laboratory device is in the making allowing for dry and saturated rocks measurements at …
