METHOD OF DEVELOPMENT OF OIL POOL Russian patent published in 2009 - IPC E21B43/20 

FIELD: mining.

SUBSTANCE: at development of oil pool it is divided into sections of development; further, oil is withdrawn via producing wells and working agent is pumped through pressure wells. When oil pool is divided into sections, pressure wells, whereto working agent is supplied from one group pumping station with one kind of working agent, and producing wells reacting with chosen pressure wells are referred to one section. The boundary of the section is drawn along boundaries of minimal absolute marks of oil pool. Number of wells of the section of development is chosen so, that shut down or change of mode of operation of one well will not influence modes of operation of other wells of the section. When performing analysis at determination of fluid pressure, producing and pressure wells are shut down simultaneously.

EFFECT: increased oil yield of oil pool.
