METHOD OF OIL POOL DEVELOPMENT Russian patent published in 2010 - IPC E21B43/20 

FIELD: oil and gas production.

SUBSTANCE: method involves deposit development for producing and injection wells, reservoir exposing in the wells, hole bottom survey in a zone of local dome elevation according to a producing well grid, injection of a driving medium through the injection wells and withdrawal of oil through the producing wells. According to the invention, development of a deposit presented by a producing formation with alternating zones of local dome elevation and local depression shall enable gravity drive to the top of dome elevation due to water in local depression, and intensive oil recovery in the zone of dome elevation. That is ensured by transforming the injection wells in the zone of local dome elevation into the producing wells, and withdrawing oil through the producing wells located in the zone of a local dome elevation so that the lower hydrodynamic level in these wells is, the closer to the top of this dome elevation the producing well is.

EFFECT: more effective development of oil pool with dome-shaped elevations due to goal water displacement towards dome-shaped elevation.
