A laboratory study of CaCO3 scaling kinetics has been undertaken to obtain information useful for prediction of CaCO3 scale formation. The induction time for precipitation has been determined in a series of experiments where SR, T and the ionic composition of the water from
which precipitation occurs, have been varied. The effect of sand from a North Sea oilfield reservoir on the rate of CaCO3 precipitation has also been investigated. Our data shows that sand enhances the rate and reduces the induction time for calcite precipitation. The formation
of solid CaCO3 has a window of metastability, which can vary from...
