The effect of carbon steel coupon surface finishing processes on corrosion in a carbon dioxide environment with high and low salinity. The system was also tested with and without chemical inhibitors.
The effect of corrosion coupon surface finishing processes on inhibitors’ performance was studied in CO2 environment. Two surface-finishing techniques aluminum oxide beads blasting and sandpaper polishing were used in this study. The resulting surfaces were characterized by white light interferometry and other techniques. The corrosion rate with and without the presence of corrosion inhibitors were evaluated using linear polarization methods. Several commercially available inhibitor products including imidazoline quaternary amines phosphate ester and mercaptans were evaluated. It was found that the protection efficiency of mercaptans vary significantly with the coupons’ surface roughness.
Keywords: surface roughness, corrosion inhibitors, interferometry.
Impact of pre-existing corrosion (pre-corrosion) on Corrosion Inhibitor (CI) performance was evaluated in conditions unfavorable of protective scale formation. CI protectiveness was significantly reduced after a 3-day pre-corrosion period.

The study of pitting susceptibility of carbon steel exposed to slightly sour service environment is conducted by using direct current and electrochemical impedance (IES). The test matrix is designed considering the oxidizing potential of the seawater as the independent variable.
This paper illustrates fifty (50) Key Perfomance Indicators (KPIs) that were developed based on industry surveys and failure analysis; application of these 50 KPIs using 10 case studies and explains cost effectiveness of various KPIs.
