A tutorial from Ohio Uversity on CO2 - H2S corrosion in Oil&Gas- As the oil and gas emerge from the geological formation they are always accompanied by some water and varying amounts of “acid gases”: carbon dioxide, 2 CO and hydrogen sulfide, H S 2 . This is a corrosive combination which affects the integrity of mild steel. Even if this has been known for over 100 years, yet aqueous 2 CO and H S 2 corrosion of mild steel still represents a significant problem for the oil and gas industry.1
