Computational models are developed to predict scale formations, compatibility and injection performance of produced water re-injection in mature hydrocarbon aquifer fields. The models are based on a robust numerical strategy that considered representative K-factors to predict correction for injectivity decline profiles. Simulations in COMSOL Multi-physics environment evaluate scaling effect to determine multi-reservoir commingling phenomenon in matured fields. Results demonstrated that geochemical scaling limit feasible and sustainable water injection performance that could impact petroleum recovery. Fracturing out of water zone was also significant near top and bottom interval cross flow of injection well requiring additional pressure of 100 to 200 psi to initiate fracturing. This requirement excluded fracturing in produce water most re-injection fields with attendant scaling effect.
