The influence of steel microstructure on CO2 corrosion. EIS studies on the inhibition efficiency of benzimidazole
TL;DR: In this paper, the authors used electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LRP) to study CO2 corrosion of carbon steel with two different microstructures: annealed, and quenched and tempered (Q&T), with and without inhibitors.

On the fundamentals of electrochemical corrosion of X65 steel in CO2-containing formation water in the presence of acetic acid in petroleum production
TL;DR: In this article, a conceptual model was developed to illustrate corrosion processes of steel in oilfield formation water system, where the anodic reactions of the steel contain a direct dissolution of Fe, Fe → Fe2+++ + 2e, and the formation of corrosion scale, FeCO3, by Fe + HCO 3 - → FeCO 3 + H+ ++ 2e.
