Corrosion by produced water containing acetic acid has been confirmed as a potential issue. Hydrocarbon production conditions have resulted in premature corrosion failures in environments containing acetic acid, sometimes due to incorrect water chemistry interpretation. This paper examines the conditions found in a North Sea oil field and presents corrosion rate modeling and laboratory testing results. The test results and predictive models are used to evaluate the effect of acetate on corrosion as a function of temperature. The testing involved both material selection and inhibition of oil and gas production environments containing acetic acid.
