Hi all,
I have some problem regarding simulation of smart water imbibition and wettability alteration in chalk core sample. In completely oil-wet case there should be no imbibition(zero oil produced) and thus I used negative pc to avoid gravity effect in oil-wet satnum table. The pc values are over the threshold value of gravity for each cell. However, still I have over 30% production eventhough I increased the pc much higher than the threshold value. I would be grateful if someone suggests any possible source of errors here.

Regards
