Waterflooding Definition




A method of improved recovery in which water is injected into a reservoir to remove additional quantities of oil that have been left behind after primary recovery.

Waterflooding usually involves the injection of water through wells specially set up for water injection and the removal of water and oil from production wells drilled adjacent to the injection wells.


A secondary recovery mechanism which involves the injection of water into the reservoir through injector well(s) to maintain reservoir pressure and drive the oil towards the producing well(s).
