Differentiation of exploration and production wells to prevent the breakthrough of water injected into the reservoir

Abstract

Abstract The equations of canonical discriminant functions and distributions were derived for deposits of the Tournaisian age of the Volga-Ural oil and gas province. This enables solution to the problems of increasing the efficiency of implementation of various contour waterflood systems, choosing exploration and production wells for focal waterflood, and estimation of the well grid density at the stage of preparation of the design documents, pressure and injection volumes, as well as making scientifically grounded management decisions for regulating the exploitation process. The method has been proposed to prevent a catastrophic breakthrough of water injected into the reservoir, which is the reason for a significant decrease in the degree of oil reserves recovery.
