Corrosion Behavior under Black Deposit on Low Cr Bearing Steels in NaCl Completion Fluid

3% Cr steel has been developed as a tubing material for CO2 oil well considering CO2 corrosion resistance. However, an oil leakage problem occurred 6 months after the start of oil production in a CO2 oil well which was completed by tubing of 3% Cr steel. 3% Cr steel was exposed to an alkaline NaCl c...
