Wettability alteration in gas-condensate carbonate reservoir using anionic fluorinated treatment

- Wettability alteration to gas wetness is proposed to Sarkhun rock.
- The treatment is consisted of an anionic fluoro-surfactant with an optimized solvent.
- The effect of this method is evaluated by various tests.
- Brine and condensate imbibition decrease after treatment.
- The relative permeability increase by a factor of 1.7.
