oa A Priori Prediction of Relative Permeability and Capillary Pressure from Pore-Scale Modelling

We reconstruct 3-D sandstone models that give a realistic description of the complex microstructure observed in actual sandstones. Pore networks replicating the microstructure of the reconstructed samples are constructed and used as input to a two-phase network model. The network model simulates primary drainage and water injection for both water wet and mixed wet systems. Predicted transport properties for different reconstructed sandstones are found to be in good agreement with available experimental data. The agreement provides a strong hint that it is possible to a priori predict average transport properties from the associated pore-scale parameters.
