Modelling Accidental Impacts To Natural Gas Storage Wells

Paper No. IPC2022-86734

This paper presents a risk assessment framework for SoCalGas’s underground gas storage sites, compliant with API RP 1171 and updated regulations. It evaluates accidental impact threats to wellheads and piping from excavations, vehicle collisions, lifting operations, and aircraft crashes. Using well-specific data and expert judgment, the models provide risk estimates for individual wells, aiding mitigation efforts and emphasizing the importance of tailored safety assessments in gas storage operations.
