Conclusion 
The possibility of increasing the final oil recovery factor through the use of new methods of 
enhanced oil recovery was studied and it was found that when using the water-gas mixture 
method for the horizon “XIV suite”, the final oil recovery can be increased by 5-6% and an 
additional 201-241 thousand tons of oil, while using the micellar method we get 8-15% of the 
effect from additional production. 
As for the technological reasons for the difference in current oil recovery factors for reservoir 
objects, this is primarily due to the number of drilled production wells, which is 3 times more in 
the first horizon than in the second. Due to geological reasons, the reservoir properties of the first 
horizon are better than those of the second horizon, as well as the energy of the gas dissolved in

oil during the development of the “XIV suite” horizon, the movement of the waters of the outer 
contour (elastic-water-pressure mode) was stronger compared to the “XV layer” horizon ". In 
general, the difference between current oil production rates is a factor due to geological reasons, 
as well as technological reasons during development.
