Averaged core porosity data plotted versus averaged core permeability data for selected wells drilled throughout the Danish onshore area and that also have been cored in the Gassum formation (large, colour-filled symbols). A porosity cut-off of 15 % was applied prior to calculating averages. The general permeability model is shown as a black solid line; cf. Figure 6. The log-based averages used for defining the general permeability model are plotted with small, open diamonds and are added for comparison. The upper and lower bounds are plotted by red and blue lines, respectively. Observe that the log-based data do not form part of the core analysis database.
