Abstract
In a method wherein valuable substances are recovered from a subterranean reservoir comprising the injection of a two phase fluid into the reservoir, uniform injectivity of the two separate phases is achieved by conducting the injected fluid to a point below the bottom of the injection interval in the well bore of the injection well through a tubing to which is attached a terminal device which is penetrated by a plurality of holes, each such hole being of sufficient diameter to reduce the bubble size of the gas phase to less than about 0.5 inches.
Claims9
In an enhanced oil recovery method for the recovery of hydrocarbons contained within subsurface earth formations wherein a two phase fluid comprising a liquid phase and a gaseous phase is injected into an injection interval in the formation through an injection well,
- the improvement wherein the injected fluid is conducted to a point below the bottom of the injection interval in the well bore through a tubing to which is attached a device which is penetrated by a plurality of holes, each such hole being of sufficient diameter to reduce the bubble size of the gas phase of the fluid to less than about 0.5 inches.
