Summary This paper presents a brief review of major techniques applied in carbon dioxide corrosion testing and monitoring. The focus is on the advantages and disadvantages of variously designed testing apparatus and monitoring devices for localized corrosion detection and assessment. Critical factors affecting the reliability and accuracy of major corrosion testing techniques are briefly discussed. It is concluded that major reasons that lead to reporting of inaccurate corrosion rates and patterns include: (i) limitations in conventional electrochemical and nonelectrochemical methods for localized corrosion measurements, and difficulties in data interpretation; (ii) challenges in simulating localized corrosion mechanisms and their changes with the extension of corrosion testing. Underdeposit corrosion testing is presented as a case to illustrate challenges in simulating localized corrosion processes and mechanisms. Experiment data have been presented to show potential difficulties of the artificial pit electrode method in evaluating underdeposit corrosion and its inhibitors. The wire beam electrode method has been used to study underdeposit corrosion with and without inhibitor present. Several interesting corrosion mechanisms have been revealed at different stages of underdeposit corrosion processes.
