The experience of implementation of polymer flooding technology at Zaburunye oil filed as a method for developing mature fields

In conditions of high depletion of oil fields and volatile oil prices, methods of enhanced oil recovery are becoming especially relevant, the use of which contributes to an increase in the oil recovery factor in addition to the use of secondary oil recovery methods. One of the technologies allowing to increase the oil recovery factor is polymer flooding technology, the distinctive advantage of which in comparison with other chemical methods is a wide range of application conditions and design variability during implementation. This paper presents the results of the application of polymer flooding technology in the oil field of Kazakhstan Zaburunye, which is in the high water-cut stage. To determine the strategy for the further implementation of polymer flooding technology and in order to find the optimal predictive development options, calculations were carried out on the developed hydrodynamic model.
