Many aspects of oilfield scale inhibition with green scale inhibi-tors (SIs) have remained untouched. For instance, the discharge of large amounts of produced water containing various types of hazardous chemi-cals, such as SIs into the environment has become a major concern. In-stead, environmental regulators encourage operators to look for greener SIs. In this study, the performance of a green SI was investigated using PHREEQC simulation. For a specific case study, two brines are considered to mix incompatibly to estimate the critical mixing ratio that has the high-est tendency to scaling. Subsequently, for 50/50 mixing ratio as the critical value, theoptimal dosage of SI and its performance in the presence of two different rocks were investigated such that 450 mg/L SI would be consi-dered as optimal value. Moreover, the simulated results show that more SI adsorption on calcite would be predicted, compared to dolomite.
