| effective porosity | |
| Flow Zone Indicator |
with Flow Zone Indicator having a Artificial Neural Network Regression on porosity and shaliness:
FZI(V_{sh},\phi_r) = ANN[V_{sh},\phi_r] |
for each lithofacies individually.
This model is very flexible in adapting to the input data and may pick up the correlation when Dual-component Cozeny-Karman permeability @model fails.
