Gas condensate reservoirs usually exhibit complex flow behaviors due to the build-up of condensate banks around the wells when the bottomhole pressure drops below the dew point. The liquid phase accumulation in the near-wellbore region forms a ring that reduces the gas relative permeability. As a result, gas production decreases and the liquid phas...
