Paper Number: SPE-221360-MS
... that as confining pressure increased, water mobility reduced, leading to its retention in the coal sample and resulting in a higher residual water saturation. These changes were reflected in a rightward shift in coal relative permeability curves. Additionally, the relative permeability of both water and gas...

... in the reservoir for both sandstone and carbonate reservoirs. 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...
