Using the method of canonical discriminant functions for a qualitative assessment of the response degree of producing wells to water injection during the development of carbonate deposits

Abstract

Abstract The article proposes an algorithm for qualitative assessment of the response degree of producing wells to water injection into wells for the conditions of oil deposits of the Tournaisian stage of the Volga-Ural oil and gas province, based on the use of the method of canonical discriminant functions (CDF). The obtained CDF equations and distributions make it possible to quickly solve the issues of assessing success of a particular waterflooding system, select wells for transferring them to injection, evaluate the density of the grid of production and injection wells, pressure and volumes of water injection at the stage of drawing up the first design documents.
