Mechanism of supercritical carbon dioxide (SC-CO2) hydro-jet fracturing

Supercritical Carbon Dioxide (SC-CO2) hydro-jet fracturing can increase gas production and reduce carbon dioxide emission, and is considered as a promising alternative for shale gas exploration. SC-CO2 hydro-jet fracturing technology has resulted in multi-fracture network in the YanChang Well of Ordos Basin, China. However, the mechanism of SC-CO2 hydro-jet fracturing is still not clear. To address the problem, experiments and specimens were...
