文摘

SC-CO2 fracturing experiments with shale were conducted for the first time. AE tests, DR and CT scans were used to observe fracture morphology. The fracture initiation and propagation of SC-CO2 fracturing was compared with hydraulic fracturing. Multiple factors influencing propagation were studied.
