Condensate (Liquid Drop Out)

Introduction

The plots below shows the idealized saturation profiles and Bourdet pressure (which resembles a radial composite system), for a gas condensate reservoir in which gas condenses within the lower pressure region near the wellbore. In the near wellbore region, the gas saturation is very low (which also means a low relative permeability to gas) thus acting as a pos itive skin for the gas system.
