METHOD FOR DEVELOPMENT OF OIL DEPOSIT Russian patent published in 2000 - IPC

Abstract RU 2149257 C1

FIELD: oil production industry. SUBSTANCE: according to method, oil is recovered from producing wells until bed pressure is reduced below pressure of saturation at which output from well starts dropping, and when gas emitted from oil starts penetrating into producing well. Prior to flooding, injected into injection wells in amount of 2-10% of bed porous volume is addition of water containing water-soluble surface-active substance with concentration of 0.01-5% in mass. Further development of deposit is carried out in operation mode aimed at maintaining current bed pressure. Application of method ensures higher oil recovery from deposit. EFFECT: higher efficiency. 3 ex
