Probabilistic Corrosion Assessment For Natural Gas Storage Wells

Paper No. IPC2022-86794

This paper highlights the need for ongoing mechanical integrity evaluations of aging gas storage wells due to corrosion risks. It proposes a probabilistic corrosion analysis to determine optimal reinspection intervals that minimize risk, using well configuration and loading data. A Bayesian approach refines corrosion growth rate distributions, improving accuracy. The findings show how tailored inspection and maintenance plans can manage integrity risks for individual wells.
