Hypergravity experiments on meter-scale porous media flow for geological carbon sequestration.

ABSTRACT: Reducing atmospheric CO₂, the main driver of global warming, is essential for climate sustainability. Geological storage offers a promising solution for large-scale, long-term sequestration; however, challenges remain in predicting subsurface CO₂ behavior and tracking its migration underground. Laboratory-scale experiments that replicate subsurface storage conditions provide valuable benchmarks for validating numerical simulations. This study investigated CO₂ migration using a geotechnical centrifuge at 50 G. The setup combined a pH-sensitive solution for visualization and a 12-sensor array for pressure monitoring during injection. Multilevel pressure data and image sequences were analyzed across early, middle, and late stages of the test. The early period
