Modelling Consequence From Gas Storage Wells

Paper No. IPC2024-130792

This paper presents a framework for assessing risks at SoCalGas natural gas storage wells, exceeding regulatory requirements. It evaluates life safety and environmental impacts using a model for ignition probabilities and an adapted PIR model. The methodology estimates risks and methane release quantities, combining safety, environmental, and societal cost metrics to assess mitigation measures, like downhole safety valves, and improve safety assessments.
