Effects of Bottom Aquifer on the Productivity of Chemical Flooding Applied to Multi-layered Heterogeneous Reservoirs
Complex geological properties of oil reservoirs affect productivity of chemical flooding.Presence of bottom-water aquifer combined with heterogcneous reservoirs has been regarded as a problem which brings out reduction of recovery factor and high water-cut.A numerical reservoir simulator is used to investigate effects of aquifer on the performance of chemical flooding.By including the effects of bottom-water aquifer, productivity decreases significantly compared with that from non-aquifer case.Results from this study emphasize the importance of an accurate assessment of performance before implementing chemical flooding, especially in unfavorable condition such as bottom-water aquifer.
