Comparative Study of Different Oil and Gas Relative Permeability Models for Iranian Carbonates [A Statistical Approach]

Laboratory measurement of relative permeability including steady state and unsteady state methods are expensive and time consuming. Due to these shortcomings, several models for predicting and obtaining two phase relative permeabilites have been developed in literature. This study involves the comparison of different oil and gas relative permeability models with three experimental datasets from laboratory tests conducted on Iranian carbonate rocks. The comparison method includes a statistical approach for determining the best model performance applied to the model predictions. It found that Koederitz model gives closest fit to relative permeability ratio obtained from experimental data sets and it is followed by Wylie and Mohamad Ibrahim.
