PROPHET input file to account for the mobile oil in the TZ. An excellent match forcumulative oil recovery was obtained between CO2-PROPHET and the full-scalesimulator, after making this adjustment. This two step comparison and match is shownon Figure 33.1,8001,600Reservoir SimulationProphet - Mobile SoProphet - Immobile So1,4001,200Cumulative Oil, MSTB1,00080060040020000 2,000 4,000 6,000 8,000 10,000 12,000Time, daysFigure 33. Analysis of Simultaneous MPZ and TZ/ROZ Oil Recovery SimulationResults, Wasson Denver UnitSimilar CO2-PROPHET and full-scale simulator comparisons were completed forthe remaining four sample oil fields (Figures 34 through 37), again showing anexcellent match between the two models when the oil saturation modification (discussedabove) was included in the CO2-PROPHET input data set.4-3 February 2006
