Experimental Study of Spontaneous Imbibition during chemically Enhanced Seawater Process

Application of smart water as an EOR methods has gained a lot of attention due to its low cost comparing to other EOR methods. However, the performance of smart water can be improved via the usage of various chemicals. In this study, the application of TiO۲ nanoparticles has been investigated on the performance of smart water. From the stability analysis by zeta potential measurements, it is concluded that effect of sulfate ions as a potential determining ions in smart water is better than Ca۲+ and Mg۲+. Hence, it is better to use smart water which its sulfate concentration is higher and is depleted in Ca۲+ and Mg۲+ ions.
