The size and often the remoteness of new oil and gas production facilities require progressively more rigid apriori assessment of the integrity of the structures for the duration of production. Carbon steel in combination with chemical corrosion inhibition is under many circumstances the most economical solution. However, inhibitors have to be qualified under relevant conditions. In order to define the term relevant, the CO2 corrosion mechanism is reviewed over a broad spectrum of parameters. New data are presented for the phenomenon of flow induced localized corrosion (FILC), so called Mesa corrosion, which has been generated in the laboratory and inhibited with a degree of protection of 99.9% at economical inhibitor concentrations. A new mechanism is discussed for FILC in the temperature range above 225°F.
