Abstract
In the petroleum industry, gas condensate reservoirs are becoming more common as exploration targets. However, there is a lack of knowledge of the reservoir behaviour mainly due to its complexity in the near wellbore region, where two phases, i.e. reservoir gas and condensate coexist when the wellbore pressure drops below the dew point pressure. The condensation process causes a reduction of the gas productivity (1). It has been reported in the literature that there is an increasing gas mobility zone due to a capillary number effect in the immediate vicinity of the wellbore in gas condensate reservoirs (2). This zone, called “velocitystripping zone”, compensates...
