Resumé
In this study, wettability alteration, fine migration, and double-layer expansion mechanisms in a particular condition are investigated to find the predominant mechanism. Amott-Harvey and zeta potential tests were performed to study wettability and ion strength variations, respectively. The results of Amott-Harvey indicated wettability alteration from oil-wet to neutral-wet conditions by LSW injection. Zeta potential measurements suggested that the reduction of salinity leads to double-layer expansion; and an increase in wetting affinity of rock towards more water-wet conditions. Also, the fine movement mechanism did not have a significant effect on this process.
