The Effect of Temperature, Pressure and Mixing Ratio of Injection Water with formation water on strontium sulfate scale formation in siri oilfield using OLI scale chem software

OLI scalechem software predicts mineral scaling potentials of 54 solids for virtually and oil and gas well and processing facility in the world. Calculation types include a generalized scale scenario for well profiles; mixing waters to find safe non-scaling ratios; reservoir saturation to simulation downhole conditions ; and facilities with simple mix and seprate abilities to simulate collection and disposal. output includes the thermodynamic scale tendencies for all solids in the model. scalechem is predictive up to 600F , 22000 psi , and 700000 ppm TDS. thus , almost any production operation can be modeled. there are several advantages over other commercially available scaling software: 1) by including all brines in the calculations , the well and processing facility are modeled more accurately; 20 scaling potential and scale builup are reported at each calculation point ; 30 automatic correction of PH and charge balance, therefore the chance of unexpected problems from bad water analyses decreases.
