Abstract

Summary

As the scale of CO storage projects increases, the potential for injected CO2 to interact with faults also increases. Field screening needs, therefore, to incorporate robust stability assessments to ensure long-term containment integrity. The study introduces FracStress+, an integrated workflow that automates fault stability screening by seamlessly connecting geologic model in Petrel with the Python-based fault stability analyzer, FracStress, via the Cegal Prizm platform. A proof-of-concept application to a hypothetical CO storage site demonstrates how the workflow enables fault stability assessment directly within Petrel. The results indicate that this approach improves efficiency and consistency by reducing manual data handling and streamlining stress analysis.
