Micro-CT images of a Bentheimer sandstone and a Ketton carbonate rock and the corresponding velocity fields:
| Bentheimer sandstone | Ketton, carbonate |
|---|---|
| Bentheimer_image.7z | Ketton_image.7z |
| Bentheimer_Ux.7z | Ketton_Ux.7z |
| Bentheimer_Uy.7z | Ketton_Uy.7z |
| Bentheimer_Uz.7z | Ketton_Uz.7z |
| Bentheimer_p.7z | Ketton_p.7z |
Velocity fields are obtained by solving the Navier-Stoke equations for incompressible single phase steady-state flow (viscosity=0.001Pa.s, density=1000Kg/m3, pressure drop=1 Pa) on the microCT images.

Sandstone and carbonate rock samples scanned dry using Xradia Versa 500 micro-CT scanner at iRocks Technologies, Beijing, China:
| Image | Rock type | Resolution (μm) | Size (voxels) |
|---|---|---|---|
| Berea | Sandstone | 2.7745 | 10243 |
| Doddington | Sandstone | 2.7745 | 10243 |
| Estaillades | Limestone | 2.6825 | 10243 |
| Ketton | Limestone | 2.654 | 10243 |
These samples are segmented according to the variation of CT contrast between rock and pore space using multi-thresholding based on Otsu’s algorithm (Otsu, 1979).
