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

Figure 2

From left to right: raw 2D image slice through each porous medium (dark = pore space; grey and white = solid phase), segmented 2D image slice (blue = pore space and black = solid phase), 3D pore spaces (blue = pore space and transparent = solid phase), and 3D rock matrix (different colours indicate different grain sizes).
