OIL DEPOSIT DEVELOPMENT METHOD Russian patent published in 2012 - IPC E21B43/20 E21B43/26

Abstract RU 2459938 C1

FIELD: oil and gas industry.

SUBSTANCE: oil is extracted through production wells, working agent is pumped through injection wells, and hydraulic fracturing of formation in wells is performed. In order to perform hydraulic fracturings in wells, deposit zones with high pressure drop, large oil reserves and pattern arrangement of not less than 1.5 ha/well are chosen. In chosen zones there chosen are production wells with skin factor that has been changed from "-" to "+" during the development and with water content of not more than 40%. Injection well with which the chosen production wells respond is determined, formation hydraulic fracturing is performed in certain injection well; after that, formation hydraulic fracturing is performed in the chosen production wells.

EFFECT: increasing oil recovery of oil deposit with coverage of larger surface area.
