Thermal Petrophysics Lab

The Thermal Petrophysics Laboratory offers a wide range of measurement methods, primarily for determining the thermal properties of rocks and minerals. In addition, mineralogical and other petrophysical parameters can be determined. The following parameters can be measured:

• Thermal conductivity (TCS, TLS, TPS; LFA) (-150°C to 1,100°C)
• Thermal diffusivity (TCS, TLS, TPS; LFA) (-150°C to 1,100°C)
• Volumetric heat capacity
• Coefficient of thermal expansion (Dil) (RT to 1,000°C)
• Porosity (by immersion weighing)
• Density (by immersion weighing, Dil)
• Permeability (TinyPerm)
• Mineralogy (XRD)

For measurements under combined in-situ pressure and temperature conditions, we are developing an autoclave based on a modified pulse method. Depending on the purpose of the measurement and the applicable sample preparation steps, the most suitable samples are either full or half cores, outcrop samples, or cuttings. To prepare rock samples (sawing, drilling, polishing), we use various in-house facilities. Over the years, we have gained extensive experience in the preparation, measurement, and scientific analysis of thousands of sedimentary, igneous, and metamorphic rocks. Depending on the rock type and application, we can saturate the samples with various pore fluids (air, water, formation fluid, heptane, isooctane, etc.) for measurement.

We offer our expertise through scientific collaborations as well as a service. For information on sample analysis and conditions and processes contact us by email.
