OIL DEPOSIT DEVELOPMENT METHOD Russian patent published in 2015 - IPC E21B43/20 

FIELD: oil and gas industry.

SUBSTANCE: according to the method geophysical survey of exploratory wells is performed by crossed dipole shear sonic imager. Oriented core is selected with further determination of directions of natural fracturing. Regional directions in maximum stress of oil-saturated rock are defined. According to findings injectors are placed along the regional directions in maximum stress. Producers are placed in between injectors thus forming developing method. Part of injectors occurred in fault zones and closer than 200m is introduced into operation as producers with their further transfer to injectors. When watering is higher than break even point and when it is required to maintain reservoir pressure at the deposit producers are transferred to injectors. Transfer of wells is made so that they form rows of injectors step by step along regional directions in maximum stress of oil-saturated rock and provide even oil displacement.

EFFECT: increased reservoir recovery due to more efficient and sound placement of well pattern within the area of oil deposit considering tectonic and geomechanic conditions of pay rocks occurring.
