The experimental investigation of effect of supercritical CO2 immersion on mechanical properties and pore structure of shale

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 respect to the horizontal direction are 0°, 30°, 45°, 60°, and 90°. Mechanical experiment results indicated that the compressive strength of shale...
