  1. Given is the range and mean (in brackets) chosen for the modelling and the supporting well-log and core data (if available) with the respective standard deviation and the number of observations (in square brackets). Vshale is calculated based on collocated co-Kriging with effective porosity (PHIGE) using a correlation coefficient of − 0.8 and the anisotropy of permeability is estimated for a vertical grid size of 1 m.
