TYPES OF RESIDUAL OIL RESERVES IN THE VOLUME OF THE RESERVOIR IN THE CONDITIONS OF THE LATE STAGE OF THEIR EXPLOITATION OF OIL FIELDS

Currently, there is no generally accepted methodology for assessing residual oil reserves by type and nature of their distribution in the reservoir. The types and distribution of residual oil reserves are determined by a complex of natural (natural) and artificial (technological) factors, such as the complexity of the reservoir structure, the degree and nature of heterogeneity of reservoir properties of rocks, the density of the well grid, their layout, the mode of reservoir development, etc.
