A comparative experimental study of shale indentation fragmentation mechanism at the macroscale and mesoscale
Low drilling rate is one of the key difficulties in shale formation, but the shale fracture mechanism during drilling operation is unclear. The shale dynamic fragmentation and crack from the multiscale perspective need to be studied. A multiscale shale indentation experiment was investigated. Compar...
