FLECAS-HT is a unique flow-through system enabling the simultaneous measurement of permeability and electrical resistivity (co-axial 4-electrode arrangement) on rock cylinders with a diameter of 30 mm and a length of 75 mm at temperatures of up to 500 °C. Currently, FLECAS-HT can be operated at a maximum confining Ar-gas pressure of 40 MPa, and a pore fluid pressure of 25 MPa. Due to the corrosive nature of high enthalpy aqueous fluids, the sample must be encapsulated with a gold tube.

In our petrophysics lab, we aim to unravel the complicated relationship between porosity and permeability in sedimentary rocks, reconstruct the origin and modification of the analyzed pore system throughout its paragenetic evolution, and precisely detect small-scale heterogeneities of petrophysical properties. Such detailed and comprehensive pore system analysis does not only complement to the understanding of the depositional and diagenetic rock-forming processes, but is of absolute essence …
