Evaluation of the effectiveness of the use of gas EOR in the development system of an oil and gas condensate field

The subject of this article is the analysis of the effectiveness of the use of gas EOR in an oil and gas condensate field. The task is to compare the calculations and assessment of the effect of the reverse injection of extracted gas into the reservoir in comparison with the effect of water injection under the same conditions, to choose the best option for the impact on the reservoir and to evaluate the effectiveness of the selected option compared with depletion development. The tNavigator software package was used to achieve the goals and objectives of the study. The results obtained indicate that immiscible displacement of oil by hydrocarbon gas is recommended for use at the research facility.
