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

FIELD: oil-and-gas industry.

SUBSTANCE: invention relates to the oil-producing industry, in particular to oil field development with flooding. According to the method the displacement agent is injected and oil is withdrawn through the system of injection and production wells. The flooding mode is changed during the development. The displacement agent is injected into the injection well in intensive mode. Using the surface measuring instruments that are a part of an automated process control system the change of extracted oil volume growth depending on the displacement agent injection volume growth until the moment of fast drop of the extracted oil volume is monitored in real time. Then the displacement agent injection volume after which the named drop occurred is recorded. Further injection into the injection well is performed in the volume below this pre-set value.

EFFECT: decrease of labour input of control of oil field flooding process during injection of the displacement agent into injection wells.
