The objective of the present study is to investigate the adsoption behavior of the sulfonated polyacrylamide (SPA)/ scleroglucan (SC) polymeric systems onto the carbonate rock surface for enhanced oil recovery applications. In addition, the effect of these polymeric systems on wettability alteration of porous media were evaluated by contact angle tests. According to the experimental results, the adsorption of SPA/SC systems was significantly more than that of the pure SC or SPA. However, the adsorption of the SC/SPAsystems decreased with increasing of crosslinker concentration. The contact angles for the aged limestone surfaces with polymeric systems were lower than that of the non-aged surface, which shows the greater potential of SPA/SC systems for wettability alteration of carbonate porous media.
