... because the capillary forces hold on to the imbibed water. Gas flowing towards the well need to pass regions of high trapped water saturation. This phenomenon is often refered to as water blockage. In wet gas systems, retrograde condensation can cause a similar phenomenon due to liquid banking near...

The proposed model evaluates the relative permeability as a function of porosity, rock absolute permeability, initial water saturation, residual oil saturation, wettability index and water saturation. Accordingly, relative permeability to water and oil...
