Gas-condensate production improvement using wettability alteration: A giant gas condensate field case study

The results showed that field gas-condensate cumulative production was improved greatly after the wettability of porous media was altered from liquid-wetting to intermediate- or gas-wetting by changing relative permeabilities for a treatment radius of 5 m around the wellbore. Production improvement in the intermediate-wetting state was maximized. Also, wettability alteration results in decreasing condensate saturation around the well and increasing the well bottomhole flowing pressure and productivity index.
