Purpose: The purpose of this article is to highlight the main problems that arise during the final stage of oil field development. Based on the identified problems using the EORgui program, Petroleum Solutions Ltd it is necessary to select the most effective method to increase oil recovery and study the most optimal tertiary oil recovery method using a hypothetical field model as an example, which will ensure the maximum oil recovery factor. Design/methodology/approach: Study of oil tertiary displacement efficiency by applying tertiary methods were performed using EORgui software from Petroleum Solutions Ltd and Petrel from Shlumberger. Findings: The results of the research show that the most optimal method of oil recovery increasing for this hypothetical field is the injection of carbon dioxide. When using this method, the oil recovery rate reaches 23%. Research limitations/implications: When using carbon dioxide, it is necessary to have sources of supply near the field, as well as increased corrosion of petroleum equipment is possible to occur. Practical implications: The use of the proposed approach is an important condition for the effective extraction of residual oil reserves for most fields developed using the reservoir pressure maintenance system. Originality/value: The article presents the characteristic features of residual oil location, reveals the conditions for effective usage of methods to increase oil recovery and their selection procedure.
