1. Box-and-whisker plot of the connected sand fraction in models based on the exposure ‘windows’ (i.e. the fraction of sandstone connected between the north and south faces of these models).
Box-and-whisker plot of the connected sand fraction in models based on the exposure ‘windows’ (i.e. the fraction of sandstone connected between the north and south faces of these models). Plots show data from model realizations containing sandbody populations with mean orientations of N090º (red) and N150º (blue). The ends of the whiskers represent the minimum and maximum values. For comparison, values of the connected sand fraction predicted by percolation theory are shown for wide (black) and narrow (grey) sandbodies relative to the model width (after fig. 15 in King 1990). The predictions assume uniform sandbody dimensions, stationary NTG ratios and random sandbody placement. Connected sand fractions in the models generally increase for a higher NTG ratio, although there is a large range of values, and are greater than those predicted by percolation theory because the model volumes are small.
