METHOD FOR DEVELOPMENT OF OIL DEPOSIT Russian patent published in 1998 - IPC

FIELD: oil production industry. SUBSTANCE: according to method, oil is recovered through producing wells. Working agent is injected through injection wells. Determined are coefficients of productivity of producing wells. Undertaken are intensifying operations in producing wells with lower coefficient of productivity. To be achieved is levelling of coefficients of productivity. Preset throughout deposit is equal pressure difference between zones of injection wells and zones of nearest producing wells. EFFECT: higher efficiency.
