| Abstract | Production in gas condensate reservoirs usually exhibit complex behaviors due to condensate deposit as the bottom hole pressure drops below the dew point. The accumulation of condensate near the well, called “condensate bank”, can lead to a severe loss of well productivity and therefore lower gas recovery. Several methods have been proposed and investigated to treat damage caused by condensate blocking. This study explores different production strategies, including commingled approach, batch perforations and gas dump-flood in order to improve the ultimate liquid recovery for gas condensate reservoirs with underlying multi-stacked gas reservoirs via compositional numerical simulation. The timing of gas dumpflood and various perforation strategies were investigated to see the most suitable operating conditions. Simulation results indicate that dumpflood shows the highest liquid recovery compared to other methods. The findings also suggest that the best timing for gas dumpflood is from the beginning and the best perforation strategy is to complete all gas layers at the same time. |
