This paper reviews the case history of a saturated oil reservoir for the past ten years and examines the EOR prospects. The reservoir is overlain by a thick gas cap and underlain by an active aquifer and thus producing by a combination of gas cap expansion and water drive with slight contribution by solution gas. Material balance calculations indicated that the water drive is becoming more active. However, the study suggested that the oil band has not migrated into the gas cap as yet. This is possibly due to the presence of less permeable shaly lime stringers in the reservoir. If the pressure decline continued causing enough pressure differential for these stringers to break down, the oil band may move into the gas cap and some of it may be lost as irreducible oil saturation. To offset this, gas injection followed by recycling is found the most suitable method to recover the reserves efficiently. This process may find application in reservoirs of a similar nature wherever a sufficient gas source exists.
