%X Numerous studies have found that alteration of rock wettability can improve the efficiency of oil displacement to increase oil recovery. Two indicators of wetting condition: adhesion behaviour and contact angles are used in this work. The results indicate that with increasing exposure time of glass sheets to OTS there is an increase in contact angle, changing their affinity from water. An intermediate wettability condition was determined by varying the immersion time of SiO2 films in silane. This condition has been shown to be favourable for oil recovery
