... during its application in H 2 S-containing environments. The plurality of mechanisms is a fundamental aspect of FeS formation that is still not clearly understood especially in H 2 S/CO 2 environments. Localized and/or pitting corrosion of carbon steel occurring in oilfields is also an aspect...
