A New Method for Predicting the Permeability of Sandstone in Deep Reservoirs

Figure 8

Comparison of the permeability prediction results and measurements of the 22 core samples: (a) Swanson parameter-based model results; (b) improved Swanson parameter-based model results; (c) capillary parachor parameter-based model results; (d) improved capillary parachor parameter-based model results; (e) SVR model results; (f) relative error of all models. The results indicate a notable match between the SVR model predicted and the measured permeability.
