The article describes a new approach to upscaling of reservoir models with a gas cap by using the dual permeability model. The proposed technique allows accurate simulation of a gas breakthrough towards producing wells while using coarse-grid models. The algorithm of dual permeability model incorporation is discussed in this paper as well as application for a real field sector model.
