The experimental task is to realize controlled long-term investigations on the permeability evolution of sedimentary rocks at simulated pressure- and temperature conditions pertinent to geothermal reservoirs.

Therefore, the investigations are performed in a set of two apparatuses that allow a variety of continuous petrophysical measurements at a maximum temperature, lithostatic- and pore pressure of 200 °C, 140 and 50 MPa, respectively. The typical flow rate is 15 ml/h and the anticipated …
