A REVIEW STUDY ON AN INTEGRATED METHOD FOR SOLVING PROBLEMS ASSOCIATED WITH THE RE-DEVELOPMENT OF WATERFLOODED FIELDS

Abstract

The purpose of this article is to develop a specific integrated method to solve the emerging problems of re-development of a flooded oil field. The following methods were used in the study: analysis, generalization, mathematical modeling and experiment. The result is a comprehensive method that can improve the efficiency and economics of post-development waterflooding. A feasibility study of the flow chart of measures to improve the efficiency of field re-development made it possible to create a comprehensive methodology for choosing stimulation methods and modern technologies that increase the efficiency of both production wells and oilfield equipment. The studies were carried out on the example of the Uzen deposit. This study showed that silica gel is the most effective technology for the development of low-permeability reservoirs in the studied field. In addition, the use of a composition of silicate microgel systems, polymers, and surfactants has been shown to improve the geological characteristics of the combined systems and the properties of the oil.
