Abstract

The main objective of this study is to provide a comprehensive investigation into the effect of Capillary number (NCa) on production from the lean gas condensate reservoirs and to show the importance of NCa in these types of reservoirs. In the current study a gas condensate reservoir has been simulated and validated using field and PVT data. The effect of NCa on the parameters such as producing gas flow rate, bottom-hole pressure, average reservoir pressure, the amount of condensate in the reservoir and the condensate saturation versus the distance from the production well has been investigated. It was found that NCa can increase the relative permeability of the gas followed by the reduction in condensate formation and pressure drop in the vicinity of wellbore. Furthermore, the results stated that NCa exists in about 10ft away from the well and affects mainly the well productivity parameters such as bottom-hole pressure and gas flow rate. However, it does not affect the average reservoir pressure and condensate throughout the reservoir as much as the near wellbore parameters.
