micelle concentration of SDS in aqueous solution. Ahmadi and Shadizadeh [93] car-
ried out mechanistic study on displacement efficiency of nanosurfactant system in oil
recovery using nanosilica and a natural surfactant derived from leaves of Z. spina-
christi. According to the experimental results, they concluded that adding nanosilica
could not significantly increase the oil recovery compared to surfactant
flooding alone.
