The recent failures in flexible pipes have motivated the exhaustive research of corrosion mechanisms on high-strength carbon steel armor wires that are the main structural compounds of those structures that mostly operate in seawater environments in the presence of carbon dioxide (CO2) and confined spaces. Recently, the literature reported discoveries about electrolyte properties (as Fe+2(aq)/HCO3-(aq.) ratio) and supersaturation, near neutral pH inside the confined space, multiphase reactions of contaminants present in CO2 gas, the formation and dissolution mechanism of FeCO3 film, and interaction of CO2 gas impurities with the corrosion scale. Therefore, this review is aimed at presenting an up-to-date narrative of the CO2 corrosion phenomenon in carbon steel, connecting background fundamentals with current data studies.

“…The most common organic acid found in oil-water brines is acetic acid. The role of acetic acid has not been well recognized and its corrosive characteristics range from corrosion promoter (16)(17)(18)(19)(20)(21)(22)(23)(24)(25) to corrosion inhibitor (26,27), as noted above. The effect of acetic acid will be analyzed in depth in a later paper.…”

Carbon dioxide corrosion of carbon steel in brine has been a recognized problem in oil production and it is becoming more common with the use of CO2-flooding as an oil recovery technique. The presence of acetic acid is systematic in oil fields, however, its role in corrosion has not been well-recognized and it is still debated. The present work was carried out, first, focusing on an understanding of CO2-corrosion of low-carbon steel and, later to ascertain the effect of acetic acid. This understanding is achieved by developing a deterministic model that explains and accounts for the experimental observations from Electrochemical Impedance Spectroscopy (EIS) data. The impedance model, based on the Point Defect Model, provides a good account of the formation and growth of a bi-layer that comprises an oxide (inner) layer adjacent the surface and a precipitated (outer) layer of siderite, FeCO3, forming on the top of the inner layer.
