A risk model was developed to identify the probability that unacceptable downhole corrosion will occur as the Arun field is depleted. Using life-expectancy estimates for the carbon steel (CS) tubing strings from this model, optimized mitigation strategies could be developed to provide cost-effective alternatives for corrosion management.
