Influence of supercritical CO2-water soaking on fracture toughness of shale: Implications for shale gas recovery and CO2 sequestration

The fracture toughness of shale influences fracture network formation and CO 2 storage stability in shale reservoirs. To investigate this effect, semi-circular bending (SCB) tests and measurements of surface energy, fracture surface roughness, and mineral compositions were conduc...
