Map view of reservoir quality based on porosity evaluation for three different zones: Berriasian to Malm \(\zeta\)4/3, Malm \(\zeta\)3 to Malm \(\zeta\)1, and Malm \(\varepsilon\) to Malm \(\alpha\). The stratigraphic subdivision is based on the sequence stratigraphic interpretation for the geothermal site SLS by Wolpert et al. (2020). It has to be noted that this reservoir quality estimation is just based on a porosity evaluation and no permeability values are included. According to Homuth (2014), Bohnsack et al. (2020) and Moeck et al. (2020), not only porosity, but also permeability in the GMB is characterized by strong heterogeneity, and they have shown that no general trend describing the porosity–permeability relationship based on stratigraphic units or lithology can be established
