Abstract
The paper highlights the results of comparative analysis of changes in the main parameters of oil and gas of the Kynovian-Pashian sediments at different stages of development (initial - 1950-1970, intermediate - 1970-1990, late - 1990 - till present). It has been seen that such parameters as bubble point pressure, gas-oil ratio, and formation volume factor decrease, while density, viscosity, and compressibility factor of reservoir oil increase. Increase in the content of paraffins, resins and asphaltenes has been observed. Such changes are indicative of the final field development stage. Maintaining oil production requires selection of the most efficient EOR methods taking into account the changes in physical and chemical oil properties.
Key words:
field, oil, physical and chemical properties, compositional analysis, density, viscosity, enhanced oil recovery
