چکیده    Today, due to the natural decline of oil exploitation, the use of methods of oil recovery, has made significant progress. however, these methods are accompanied by accumulation and deposition of mineral deposits in oil field installations. in the present study, aqueous solutions, strontium sulfate, barium sulfate, manganese sulfate and nickel sulfate are studied, in terms of euniquac model and genetic algorithms. based on the findings of this article, as temperature increases, in order to increase the solubility of the system, the ionic strength decreases; but with increasing pressure, the solubility of barium sulfate increases. meanwhile, in this article, to evaluate water activity, aqueous solutions of manganese sulfate and nickel sulfate is studied.
