The article describes Dragon deposit operational facilities development state. An analysis of the central and southern sections of the field development showed that the oil recovery factor in these areas is significantly lower compared to the approved one due to low producing and injection wells grid density. According to complex geological and geophysical studies data, exploratory and advanced production wells drilling within the southern part (RC-5, RC-9) of the central section structure, oil deposits were identified in the crystalline basement, in the Upper Oligocene and Lower Miocene sediments. It has been established that a drop in reservoir pressure is one of the main reasons for a decrease in the bottom-hole production zones processing efficiency, and chemicals, the use of which allows you to get a good effect at normal pressure, can become less effective with a sharp reservoir pressure drop.
