Representative Elementary Volume of Rock Using X-Ray Microcomputed Tomography: A New Statistical Approach

Figure 5

Empirical porosity variation (blue points) in the subvolumes of the five samples examined: (a) glass bead pack, (b) sand pack, (c) Bentheimer sandstone, (d) Mount Gambier carbonate, and (e) St. Bees sandstone. The green line indicates the arithmetically averaged porosity of the sample. The vertical red line indicates the REV found by visual inspection.
