The interactions between supercritical carbon dioxide (ScCO2) and shale significantly affect shale reservoir exploitation. This study investigates the effect of ScCO2 immersion on the mechanical behavior and microstructure of shale with inclined layering. The orientations α of the bedding plane with...
