Evaluating the potential of a sedimentary basin reservoir to securely store CO benefits from a comprehensive understanding of the geochemical reactions that take place once CO is injected into a formation. In particular, models that predict the transport and reaction of CO within a reservoir require a definition of the types of reactions affected by enhanced levels of CO and how the kinetics of these reactions will affect a heterogeneous mineralogy and formation waters within a reservoir over time. In this review we evaluate rate models used to describe mineral dissolution kinetics and compare the range in values reported for the kinetic parameters used to describe the reactivity of vari..View full abstract
