  • METHODS FOR MANAGING FORMATION VOIDAGE REPLACEMENT IN WATERFLOOD PRODUCTION OPERATIONS TO INCREASE OIL RECOVERY
    Publication number: 20180283149
    Abstract: A method for waterflooding of a reservoir in a subterranean formation includes (a) appraising the reservoir to obtain a plurality of physical properties relating to the formation and the oil in the reservoir. The plurality of physical properties include a reservoir pressure and a Bubblepoint pressure of the oil in the reservoir. The method also includes (b) determining that the Bubblepoint pressure is greater than 60% of the reservoir pressure. In addition, the method includes (c) waterflooding the reservoir at a voidage replacement ratio (VRR) less than 1.0 based on the determination in (b).
