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.
