Naturally Fractured Reservoirs are consisting of two systems: porous matrix and opened fractured. As production starts in Naturally Fractured Reservoirs (NFR), three zones would create vertically: gas invaded zone, oil zone and water invaded zone. Gravity drainage is the dominated recovery process in gas invaded zone, where the oil is displaced by gas. The ultimate oil recovery and oil flow rate are controlled by Block-to-Block effect. In this research the capillary continuity and reinfiltration process will be evaluated in details.
