a Correlation between permeability values determined by argon and air measurements, including error bars (standard deviation) if available, b permeabilities measured with argon (K_Ar) and air (K_Air) plotted against the corresponding maximum hydraulic length \({l}_{\mathrm{max}}^{h}\) (m), where most of the mercury is injected into the sample as well as the r₃₅ value, corresponding to the pore diameter at 35% mercury saturation. Error bars indicate the standard deviation if available. c Air- and Ar-derived permeability values related to porosities including error bars (standard deviation) if available and method-specific contours in the background for better data range visibility. d Ar permeability distribution across the sampled layers including error bars (standard deviation) if available and e is showing the horizontal permeability variation along bed B1 across a normal fault.
