ABSTRACT:One of the effective metods of controlling scale formation is the use of inhibitors. The addition of scale inhibitor to the feed water would be an effective method to reduce or prevent scale formatio in oil fields and water system. For this reason, this work pertain to study the effect of prepared antiscalants on the solubilization of sparingly soluble inortanic salts such as calcium carbonate and calcium sulfate. Different types of surfacants and organic anions based on phosphorylated and phosphomethlation of alkanolamine, and phophomethlation pound as scale inhibitors has bee evaluated using the standard test method (NACE). The reults inticate that the amounts of soluble scales are strongly affect ed by inhibitor concentrations. The effectivness of inhibitors to prevent the nucleation and crystallization of the supersaturated calcium slfate are signigicantly higher than the correspondnig calcium carbonat e solution.
