Keywords: residual oil, zonal distribution of oil and reservoir properties, comprehensive study of deposits with residual oils, monitoring of physical-chemical properties of oils

Annotation:

The article discusses the reasons for the formation of residual oil reserves in a productive reservoir. Two reasons for the formation of poorly drained zones are shown: firstly, those, depending on the reservoir properties of the reservoir and various natural factors, and, secondly, on fluid filtration. The results of the analysis of hydrodynamic researches (HDR) data of formations and wells in combination with studies of PVT and physical-chemical properties of reservoir oils using a data bank on the properties of oil are presented.
