This allowed the quantitative characteristics of displacement mechanisms to be determined and the correctness of the used approach to be verified. The oil displacement mechanisms characterized in this way were implemented in the numerical model of a real oil reservoir. The results of simulations for crude oil depletion using the above methods have been obtained in this model, showing their beneficial effect on the degree of depletion of oil resources. The dependents of production results on various operational parameters were obtained allowing to assess the effectiveness of the analysed methods for enhanced oil recovery.
