Corrosion in the Oil Industry - slb.com

diminish. In oil production, Fe++ ions are removed by reacting with oxygen [O 2], hydrogen sulfide, or carbon dioxide. The corrosion products are precipitates or scales of rust [Fe 2O 3], iron sulfides [FeS x] or iron carbonate [Fe 2CO 3]. Excess electrons flow away from the anodic region to a site where they form a cathode, and where reduction occurs.
