Wettability Alteration - A Unique Tool for Improved Recovery in Gas Condensate Reservoir

Wettability of reservoir rock is critically important property to determine displacement efficiency of injecting fluid and ultimate recovery. Wettability affects capillary pressure, relative permeability, initial water saturation, electrical properties of reservoir rock and mostly oil displacement efficiency. With the use of chemical, we altered wettability of core sample from liquid to gas wet and then we have studied the effect of altered wettability on relative permeability of oil and gas and also its’ effect on the recovery of oil and gas below dew point pressure in gas condensate reservoir and the effect on well deliverability.
