Effects of CO2-water-rock interactions on the fracture performance of transversely isotropic shale: Transition from strengthening to weakening

Key Points

• The study shows a transition of fracture performance in transversely isotropic shale.
• Key evidence indicates a shift from strengthening to weakening based on CO2-water-rock interactions.
• Assessment of interactions evaluated through fracture performance metrics in different rock conditions.
• These findings highlight the need for further geological considerations in CO2 sequestration projects.
