Initialization of water saturation can be achieved by Sw-height relationship derived from core data and water saturations calculated from logs. A rock typing scheme based on facies, diagenesis and MICP/ BOCP ensures consistency between the initial water saturation functions and the relative permeability. Therefore saturation function approach has to account rock type scheme for consistency and better match. Seismic inversion result or AVO study can help to condition 3D saturation model for the initial Sw match.
Either Pc curves or J function or any other method for initialization that will be agreed with our client will be applied for initial Sw modeling.
