AbstractThe wettability of the solid powder of silica gel was determined via a modified Washburn equation expressed as contact angles. The interfacial tension (gamma) between the dodecane and the dilute sodium dodecyl benzene sulfonate (SDBS) aqueous solution was obtained using the spinning drop (gamma < 10 mN m(-1)) or drop vol;me methods ( > 10 mN m(-1)). Contact angle changes for SDBS aqueous solutions on the surface of a silica gel powder were studied. The average aggregation number of SDBS micelles in aqueous solution was determined using the fluorescence quenching method. The relationship between the wettability of the powder surface, the critical micelle concentration (CMC) of SDBS and the mimic oil recovery of the resident oil on the powder surface has been explored. It has been found that good residual oil recovery was achieved by surface wettability changes at the interfacial tensions around 4-5 mN m(-1). which is far from the 'ultra low' condition (less than or equal to 10(-3) mN m(-1)).
