Selection of waterflooding systems for enhanced oil recovery by solving two-phase filtration problem

On the basis of analytical solution of two-phase flow problem, an express method is proposed for calculation of advantageous system of oil reservoir development, function of production and injection wells under the given arrangement. The method allows real-time obtaining of one of advantageous variants of field development system with hundreds of wells. The computational efficiency of the proposed method is investigated on synthetic reservoir simulation models of a nine-spot development element.
