Database of petrophysical properties of the Mid-German Crystalline Rise

Abstract. Petrophysical properties are a key element for reservoir characterization but also interpreting the results of various geophysical exploration methods or well logs. Furthermore, petrophysical commonly used to populate numerical models and often critically governing model results. Despite common need detailed properties, data still very scarce not available area interest. both online research published property measurements compilations, as dedicated measurement campaigns selected which require comprehensive laboratory equipment, can be time-consuming costly. To date, most focused on limited selection parameters only, hence researching needed account thermal–hydraulic–mechanical behaviour rock types settings, laborious. Since deep geothermal energy in central Europe, majority potential resource is assigned crystalline basement, database comprising densities, porosity, matrix permeability, thermal (thermal conductivity diffusivity, specific heat capacity) mechanical compressional shear wave velocities, unconfined compressive strength, Young's modulus, Poisson's ratio, tensile strength triaxial was compiled from conducted at HydroThermikum lab facilities Technical University Darmstadt.
