METHOD FOR PRODUCTIVE BED DEVELOPMENT Russian patent published in 2006 - IPC E21B43/20 

FIELD: oil industry, particularly for stacked oil pool development.

SUBSTANCE: method involves producing oil through producing wells and injecting working agent through horizontal injection wells in cyclic regime. The working agent is formation water, which is injected in daily cycles including injection and idle stages. At injection stage injection pressure not exceeding bottom-hole pressure is set at producing well head. Working agent volume to be injected is taken to be equal to daily output from neighboring reactive producing wells with taking into account outflow compensation. At idle stage well is stopped till the set of day. Current formation pressure equal to 50-90% of initial pressure is regulated by injection and production operations.

EFFECT: increased oil recovery.
