METHOD OF OIL POOL DEVELOPMENT Russian patent published in 2014 - IPC E21B43/16 

FIELD: oil and gas industry.

SUBSTANCE: during development of oil pool at least a part of wells with horizontal or inclined curve boreholes is made. Injection of a working fluid is made through injectors and oil extraction is made through producers. Operations are made at sections where collectors have natural fracturing and thickness less than 5m, they are placed at a distance of 6m from the water-saturated formation. The horizontal curve borehole is made as per the curved trajectory with its curve in azimuth with intensity up to 4°/10m and length providing the cross-section of the fracturing direction under angle from 0 up to 90 degrees.

EFFECT: higher oil recovery of the deposit.
