Importance of water Influx and waterflooding in Gas condensate reservoir
The possibility of losing valuable liquid and lower gas well deliverability have made gas condensate reservoirs very important and extra emphasizes are made to optimize hydrocarbon recovery from a gas condensate reservoir. Methods like methanol treatments, wettability alteration and hydraulic fracturing are done to restore the well deliverability by removing or by passing the condensate blockage region. The above mentioned methods are applied in the near wellbore region and only improve the well deliverability temporarily while gas deliverability is maintained permanently by maintaining reservoir pressure above the dewpoint pressure by injecting fluid-traditionally produced gas.
In this report, the importance of water influx and water flooding on the performance of gas condensate reservoir is studied through fine gridded compositional simulation models. It is shown that water drive can significantly increase the ultimate oil and gas recoveries of a gas condensate reservoir.
