EFFECT OF Ca2+ ON C02 CORROSION OF CARBON STEEL

In the sweet oil and gas fields, the formation water contained many cations such as Ca2+, which lead to precipitation of scales and may influence the susceptibility to uniform and localized corrosion during C02 corrosion. Previous research related to effect of Ca2 + concentration in localized co...
