Abstract:
Enhanced oil recovery methods are used to recover the percents of oil that are not naturally recoverable from reservoirs. Water injection as a secondary recovery is used to maintain the pressure in water-drive reservoirs. An important point for having a successful injection is the compatibility of injection and formation waters. In this study, using the Scale soft pitzer software and Persian Gulf water and formation water chemical analysis has been measured in the laboratory. Scaling index strontium sulfate (celestite) and iron sulfide at different temperatures (80-210 ◦F ) and pressure (15 - 4000 Psia) is predicted in Iran Siri oilfield. The results show that iron sulfide scale has just been formed in siri-c oilfield and the formation of strontium sulfate in Siri oilfield is very low
