Zusammenfassung
The growing interest in exploiting supercritical geothermal reservoirs calls for the understanding of the physical properties of rocks and the fluids they are interacting with in a high enthalpy environment. Here, we present a new flow-through cell capable for petrophysical measurements of fluid saturated rocks at high pressure and temperature. The permeability and electrical resistivity of a quartz-gabbro from a fossil hydrothermal system on Iceland were determined between 25 – 350 ̊C at a controlled pore pressure of 22.2 MPa. The measured resistivities are correlated with fluid resistivity data obtained in an attendant study (see part I of this paper).
