Table 5 Relative porosity (ΔΦ/Φ) and permeability (Δk/k) changes for the investigated rock at a depth of ~ 2 kmTVD with an assumed vertical effective stress of dp ≈ 25 MPa (according to Drews et al. 2020), calculated after Eqs. (18) and (20), respectively

From: Petrophysical characterization, BIB-SEM imaging, and permeability models of tight carbonates from the Upper Jurassic (Malm ß), SE Germany
