The use of corrosion inhibitors to protect assets from carbon dioxide and hydrogen sulfide induced corrosion has been the most universal method implemented in the oil and gas industry. Imidazoline derived inhibitors have been amongst the most popular and effectively used in sweet and sour environments for several decades. A particular interest emerged around the development of novel additives and low dosage corrosion inhibitors to comply with the properties of the new generation of corrosion inhibitors (nontoxic and green). The performance of the Imidazoline-derived CI in combination with a novel additive was evaluated using Linear Polarization Resistance (LPR), Anodic-Cathodic Polarization (ACP) and Electrochemical Impedance Spectroscopy (EIS). The results showed the synergistic and enhancer effect of the mixture when the novel additive is present in the formulation in low doses. The three methods were performed with a rotating cylinder electrode at high rotation to evaluate the film persistency of the mixture of corrosion inhibitor/novel additive. A high potential was found it in the mixture of Low Dose of Novel Additive chemistry with Imidazoline to mitigate corrosion.
