Burial depth interval of the shale brittle–ductile transition zone and its implications in shale gas exploration and production
Shale Brittleness Fracture Overconsolidation ratio (OCR) Confining pressure
2018/4/2
Brittleness and ductility of shale are closely related to shale gas exploration and production. How to predict brittleness and ductility of shale is one of the key issues in the study of shale gas pre...
