PROCEDURE FOR DEVELOPMENT OF OIL DEPOSITS Russian patent published in 2011 - IPC E21B43/26 

FIELD: oil and gas production.

SUBSTANCE: procedure for development of oil deposits by inter-contour effect to object of development through pressure wells with pumping replacing agent consists in creation of hydraulic fractures along totality of producers and pressure wells, in withdrawal of fluid through producers, and in pumping fluid for maintaining reservoir pressure through pressure wells. According to the invention there is performed directed hydraulic fracturing in similar wells maintaining efficient hydraulic communication between them in such way, as to facilitate uniform front of high pressure in rows of pressure wells during pumping, while in zone of fluid withdrawal through producers there is facilitated uniform front of low pressure.

EFFECT: raised degree of withdrawal of movable stock of oil and reduced time of development.
