Quantitative Risk Framework For Natural Gas Storage Wells

Paper No. IPC2022-86833

A risk assessment framework for SoCalGas’s underground gas storage sites in California, aligned with API RP 1171 and regulations, evaluates 80+ failure mechanisms using a dynamic fault tree. It prioritizes high-risk threats, while simpler models are used for less critical ones. The modular design incorporates factors like monitoring and wellhead spacing, enhancing integrity management activities such as erosion and pressure monitoring.
