Optimization of the development of multilayer productive formations by changing the parameters of well completion and their location

Abstract

Due to the increase in the volume of hard-to-recover oil reserves, in complex deposits, reservoirs with reduced filtration properties, fields in remote, without infrastructure, new tasks have appeared that need to be solved when developing these reserves so that it is cost-effective. It requires the use of new methods for selecting methods and systems of development with the simultaneous introduction of new methods for intensifying production and increasing oil recovery. The article investigates a method for improving the efficiency of the development system of a layered and heterogeneous productive formation of the «ryabchik» type by controlling the parameters of the well grid and well completion. The analyzed method of optimization of development will increase the efficiency of extraction of hard-to-recover oil reserves and increase the degree of their production. Proposals have been made to increase the efficiency of the development of a formation of the «ryabchik» type. Keywords: horizontal well; trunk orientation; optimization of the well grid; development efficiency; multilayer formation.
