ABSTRACT:
A fluid injection induced oil recovery process wherein fluid is injected into a formation via a plurality of fluid injection wells and is produced from the formation via a plurality of production wells, and excessive flow and channeling through a "thief" region between one injection well and one production well is controlled by successively (1) shutting in the one injection well and operating the one production well for a first period of time and (2) operating the injection well and shutting in the production well for a second period of time. This sequence is repeated as many times as desired. The sequence can be modified by adding the additional step of (3) operating both wells for a third period of time. This alternative sequence is also repeated as many times as desired.
