... and the occurrence of localized and/or pitting corrosion, especially in complex oilfield environments containing H 2 S, CO 2 and other acid gases. In addition, multiple cations such as Fe 2+ , Ca 2+ and Mg 2+ can further complicate the system. The presence of such cations in the brine chemistry could also impact...

.... The CO 2 diffuses from the bore into the annulus through the polymer sheets. Corrosion of the armor wires in contact with the water will result in high levels of Fe 2+ and bicarbonate (HCO 3 - ). Several studies have indicated that SCC may occur in solutions with high HCO 3 - concentration...

... ABSTRACT In order to implement an effective iron scale mitigation strategy, operators first need to identify the main source of iron in the system. Establishing the main source of Fe 2+ in higher temperature sour wells where iron sulphide and iron carbonate are formed can be problematic...

... when utilizing Fe 2+ as the energy source to fix CO2 into glucose. The fast reaction of Fe 3+ with Fe 0 to form Fe 2+ was prevented in the systems containing UNS S30400, probably by the chromium rich passivating layer formed on UNS S30400 surface to block the accessibility to Fe 0 . Without Fe 2...
