Study on Wellbore Stability and Failure Regions of Shale considering the Anisotropy of Wellbore Seepage
The hard and brittle shale formation is prone to collapse and instability, and the penetration of drilling fluid along the bedding reduces the mechanical properties of rock near the borehole wall, resulting in serious downhole accidents. Therefore, in this paper, the geomechanical parameters of the...
