Analysis of wettability alteration in low salinity water flooding using a zeta potential-based model

This study introduces a zeta potential-based model which connects low salinity water flooding oil recovery to the reservoir wettability. The assumed that wettability is controlled by electrostatic forces exist between rock-brine and oil-brine interfaces. Therefore, it links potentials present at corresponding Using model, various literature data were simulated then statistically compared trend of factor with indicator values. Pearson correlation coefficient was used for statistical analysis. results from suggested outputs computed other pre-existing models alteration. simulation outcome indicated strong relationship exists produced calculated exceeded 0.7 all experimental cases simulated. However, most showed weak relationships values factor, some producing below 0.2. highlights role interfaces on alteration during flooding. can be utilized in decision making implementation works.
