Abstract
A traceable polymeric scale inhibitor comprises a traceable phosphinate moiety and a scale inhibiting moiety including carboxylate functionality. The polymeric scale inhibitor may be derived from polymerization of a mixture comprising a phosphinate compound and a vinyl-carboxylate monomer. The traceable polymeric scale inhibitor may be used for oilfield applications. A method of reducing scale formation comprises treating the fluid subjected to scale formation with the traceable polymeric scale inhibitor. The method provides a means to determine when additional treatment of scale inhibitors is needed, which conduit or wellbore needs additional treatment of scale inhibitor, and how much additional scale inhibitor is needed in the repeat treatment to provide effective inhibition of scale formation.
