The wetting behavior of under oil-microbial solution on carbonate rocks was measured using contact angles. Fluids were considered as wettings if their contact angles with surface were less than 90° and considered nonwetting if their angles were greater than 90°. In the presence of bacteria, crude oil contains lower asphaltene and oils contains higher asphaltene concentration. It was found that increasing sulfur concentration increases the contact angle and thus affect the contact angle and alter the system wettability and overall recovery efficiency.
