Mechanism of fracture expansion in deep shale by supercritical CO2 fracturing

Meitan xuebao
Deep shale reservoirs are subjected to high-temperature and high-stress conditions, under which the mechanical properties of shale gradually transform from elastic-brittle to ductile-plastic behavior, making it difficult to form complex fracture networks.
