Pipeline Internal Corrosion - OilfieldWiki

CO2 is composed of one atom of carbon with two atoms of oxygen. It is a corrosive compound found in natural gas, crude oil, and condensate and produced water. It is one of the most common environments in the oil field industry where corrosion occurs. CO2 corrosion is enhanced in the presence of both oxygen and organic acids, which can act to dissolve iron carbonate scale and prevent further scaling. Carbon dioxide is a weak acidic gas and becomes corrosive when dissolved in water.
