Changes

Gas condensate reservoirs are also referred to as retrograde gas reservoirs, duly named in reference to the phase behavior of the fluid, which exhibits retrograde condensation over time (Dandekar, 2006). This can be seen in [[:file:AlAhmadiTawfiqFigure1.jpg|Figure 1]]. As gas is produced, the reservoir pressure decreases until it reaches the dew point (point 2), where the first drop of liquid forms. The percent liquid saturation increases as pressure is decreased, reaching a maximum (point 3). The liquid saturation then decreases as pressure is decreased further and the liquid re-vaporizes (red line); exhibiting the referenced retrograde condensation.<ref name=Parvizi_2009 />
