Combination of a constant composition (CC) crystallization approach together with atomic force microscopy (AFM) has enabled the elucidation of the mechanisms of the scale (crystals) formation and dissolution at the molecular level. The new model reveals that the surfaces may be unable to support etch pits of sufficient size so as to be able to continue the dissolution process when the crystals are at the nanoscale. These small crystals resist dissolution even though the aqueous phases may be undersaturated. In addition, the inhibitory effectiveness of bisphosphonates for both the formation and dissolution of scale (Ca-P crystals) is discussed.

The formation brine in a giant carbonate reservoir had high total dissolved solids  and high calcium ion concentration.  The absence of any major sulfate-scaling problem in this field despite the seawater flood for more than 25 years is attributed to the injection of compatible aquifer waters before the onset of seawater injection.
