Calibration well-specific deviation from the maximum pore pressure gradient of the average best fit basin models. For each model the used clay content (40%, 70% or 90%) of the permeability model from Yang and Aplin (2010) or the temperature-dependent permeability model (KT; c.f. Equation 2) of the Chattian (Ch), Rupelian (Ru), Lattorf/Sannoisian (LS) and Upper Cretaceous (UC) are specified. The black-dotted box indicates the acceptable pressure gradient deviation of 0.15 g/cm3. The numbers mark the model number used in Table 4. Model descriptions highlighted in green indicate models which yielded acceptable pore pressure deviations at the calibration Wells A–D
