The viability of hydrogen storage in bedded salt caverns hinges on understanding the geomechanical challenges posed by anisotropic stress states and complex geology such environments. This study presents a comprehensive analysis focusing proposed cavern within Carribuddy Formation Western Australia, characterized its interbedded layers. paper introduces new workflow, encompassing 1D 3D modeling techniques to provide detailed changes mechanical properties state formation allowing identify initial optimal operational pressures for underground storage. Initial models evaluated in-situ stresses, while subsequent simulations, enriched data from neighboring wells, stress, strain, displacement responses walls internal pressure changes. pinpointed an safe gas range between 3000 4000 psi, attributing this margin robust characterization formation. Our findings underscore significance high-resolution identifying caverns, ensuring both safety structural integrity.
