Current Setup

  • Raw volume: Kirby_2d25um_binary.raw
  • ROI size: 300 x 300 x 300 voxels
  • Selected ROI origin: (700, 0, 700)
  • Conductance model: generic_poiseuille
  • Viscosity model: tabulated water viscosity from thermo, 298.15 K
  • Boundary pressures: pout = 5.0 MPa, pin = pout + 10 kPa/m * L

Kirby directional permeability

Interpretation

The current workflow predicts Kirby with a quadratic-mean permeability error of 104.85% relative to the Table 1 experimental reference. This case should be interpreted together with the cross-sample summary in DRP-317 sandstone validation overview.
