  • Estimation of oil recovery in foam flooded hydrocarbon reservoirs
    Patent number: 10282385
    Abstract: A method for the estimation of oil recovery factor in a foam flooded hydrocarbon reservoir. The hydrocarbon reservoir is divided into three sweep sub-zones, with sweep efficiency and displacement efficiency for each zone being estimated. The oil recovery factor is determined as a function of porous volume injected, based on the sweep efficiency and displacement efficiency.

  • ESTIMATION OF OIL RECOVERY IN FOAM FLOODED HYDROCARBON RESERVOIRS
    Publication number: 20170175493
    Abstract: A novel method for the estimation of oil recovery factor in a foam flooded hydrocarbon reservoir. The hydrocarbon reservoir is divided into three sweep sub-zones, with sweep efficiency and displacement efficiency for each zone being estimated. The oil recovery factor is determined as a function of porous volume injected, based on the sweep efficiency and displacement efficiency. The method provides good results with higher certainty, at a higher rendering speed and using less input data, than conventional numerical simulation approaches.
