Opis:: 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.

Opis:: Purpose: The purposes of this article are to study the effective ways of increasing the hydraulic efficiency of gas gathering pipelines of the Yuliivskyi oil and gas condensate production facility (OGCPF); to calculate the operation efficiency of gas gathering pipelines of the Yuliivskyi OGCPF and develop a set of measures to monitor their condition and improve their hydraulic characteristics; to investigate the technology of cleaning the inner cavity of flowlines of gas-condensate wells with foam, to perform the feasibility study on the prospects of its application in practice. Design/methodology/approach: The technology of cleaning the inner cavity of flowlines of gas-condensate wells with foam was investigated to objectively evaluate its application and determine the effectiveness of this measure. The research was carried out within the framework of research and development work by the specialists of the Ukrainian Scientific Research Institute of Natural Gases. Findings: The results of production studies showed that due to cleaning the flowlines of gas-condensate wells (No.85 and No.60) from the accumulation of liquid, the coefficients of their hydraulic efficiency increased by 12% and 7%, respectively. Measures taken to clean the inner cavity of the flowlines from liquid have proven their efficiency and can be recommended for other flowlines of wells at other production fields. Research limitations/implications: Based on the characteristics of gas gathering pipelines, it is reasonable to conduct experimental studies on the use of the proposed technology of cleaning the inner cavity with foam in the case of increasing its multiplicity. Practical implications: Using the wells of the Yuliivske oil and gas condensate field as case studies, the operating parameters were measured and the pressure losses along the length of the flowlines were calculated. According to the results of calculations at two wells (No.85 and No.60), a significant excess of the actual value of the flow friction characteristic over the theoretical value was established. To reduce excessive pressure losses due to the presence of liquid and improve the hydraulic characteristics of the wells, their inner cavities were cleaned using foam with the expansion ratio from 40 to 100. Originality/value: It is important to note that the advantages of foam piston include: ease of use, no occurrence of hydraulic shocks and preventing stuck during movement in the gas pipeline, application in both straight and inclined sections, no wear of the elements of the cleaning equipment, a rather efficient cleaning of gas pipelines.
