Abstract
Currently, most of the oil fields in the West Siberian oil and gas province are in the final stage of development. There is water-cut in production, a decrease in oil production, and the structure of residual reserves deteriorates. The search and application of the most successful scientific methods and technologies for improving oil recovery in the development of fields is quite an urgent task.
It should be taken into account that hydrophobic reservoirs are common in the oil fields of Western Siberia, and when applying the method of reservoir flooding, this fact should be taken into account and a more detailed approach should be taken to the study of capillary forces to prevent flooding of productive objects. Despite the good knowledge of the West Siberian megabasin, some fundamental issues of its structure and oil and gas potential remain debatable.
The article proposes methods for improving oil recovery of the BS10 formation of the Ust-Balykskoye oil field based on the study of capillary pressures in productive reservoir formations, and provides recommendations for the placement of injection wells. The study of the capillary properties of reservoir rocks will significantly improve the efficiency of exploration and field operations in oil fields.
