Fractured Anhydrite as a Geothermal Source in a Low Enthalpy Context (Southern Permian Basin, Netherlands)

Increased heat flow associated with the presence of salt domes could be beneficial for geothermal energy applications in a low enthalpy nvironment. Anhydrite layers within such salt domes could be a potential geothermal target. These layers are known to undergo brittle deformation, which in turn can lead to the generation of a fracture network, able to facilitate fluid flow. We investigate the suitability of such an anhydrite layer in the Southern Permian Basin (The Netherlands) by means of seismic interpretation and seismic attributes. Our results reveal the presence of an anhydrite layer and evidence of brittle deformation and fracturing on the macro scale. Lastly, we identify future steps for a more comprehensive resource assessment of such a concept
