Leopard_2d25um_binary.raw - ROI size:
300 x 300 x 300voxels - Selected ROI origin:
(0, 0, 0) - Conductance model:

thermo,298.15 K - Boundary pressures:
pout = 5.0 MPa,pin = pout + 10 kPa/m * L
Key Results¶
| Quantity | Value |
|---|---|
| Experimental porosity [%] | 20.22 |
| Full-image porosity [%] | 19.50 |
| ROI porosity [%] | 19.50 |
| Network absolute porosity [%] | 20.01 |
| Experimental permeability [mD] | 327.0 |
| Kx [mD] | 475.09 |
| Ky [mD] | 259.72 |
| Kz [mD] | 131.63 |
| Arithmetic mean permeability [mD] | 288.81 |
| Quadratic-mean permeability [mD] | 321.71 |
| Relative quadratic-mean error [%] | -1.62 |
Interpretation¶
The current workflow predicts Leopard with a quadratic-mean permeability error of
-1.62% relative to the Table 1 experimental reference.
This case should be interpreted together with the cross-sample summary in
DRP-317 sandstone validation overview.
