One of the enhanced oil recovery (EOR) methods is injecting gas or water into reservoir. Persian Gulf seawater is used for injection into Siri and Nosrat oil reservoirs. Water injection, despite the benefits, caused sedimentation. In this study, formation of sediment in mixing of formation water and injection water has been discussed. To predict sedimentation by mixing of waters, NRTL equation has been used and the relative super saturation parameter versus the percentage of seawater is plotted in different temperatures and pressures. Results showed that increasing the temperature, decreases amount of Barium sulfate sediment and increases amount of Strontium and Calcium sulfate sediment. Increasing in pressure reduces the amount of sulfate sediments. Experimental and modeling results were compared. To verify the model, results of modeling were compared with experimental results.
