Abstract: The performance of an Imidazoline based commercial corrosion inhibitor in CO2
corrosion of a gas-well tubing steel was studied by employing Electrochemical Impedance
Spectroscopy (EIS) technique. Inhibitor performance was investigated by means of its efficiency at
various concentration and also its behavior at various exposure time. EIS results showed that
inhibitor interaction to the electrode surface obeys Lungmuir adsorption isotherm. Interpretation
of some parameters such as Rct, Rpf, Cdl, and Cpf associated to the equivalent circuit fitted to the
experimental rsults showed that not only inhibitor efficiency and surface coverage improve by
increasing in inhibitor concentration in the solution but also at constant inhibitor concentration
both surface coverage and efficiency improve with exposure time and reach to their highest value
after 4 hours.
