According to the results of litho-petrographic investigations the rock reservoirs discovered by Lyzhiay-1 (2129 m), Vezhaiciay-11 (2046,8 m ) boreholes were formed under the coastal-marine conditions, and discovered by the Lyzhiay-1 (2127,6 m) borehole they were formed under the sea shelf conditions. Matrix of the rocks is characterized by high reservoir properties: permeability (taking into consideration the Klinkenberg effect) changes from 0,1×10-15 м2 to 80,1×10-15 м2 and open porosity changes from 4,1 to 13,3 %. The experiment has shown that in relation to the volume of effective pores and depending on the level of rock permeability, the structure of oil saturation is the following: free oil – 34–67 %, film oil – 30–41 %, absorbed oil – 2–30 %. The coefficient of water-oil displacement during waterless period is 0,34–0,67 and the maximum coefficient with the usage of secondary oil recovery enhancement methods during watering is 0,46-0,77.
