To date much emphasis on scale inhibitor evaluation and studies of scale kinetics has been given to studies using static beaker tests. This paper describes an electrochemically based technique, which allowed the extent of scaling on a solid surface to be determined in presence and in absence of scale inhibitor. The ability of the technique to provide kinetic information on surface scaling will be demonstrated with two kinds of scale. Finally the potential for this technique as a method for on-line monitoring of scale formation downhole will be discussed.
