Discrete element modelling of stress-induced instability of directional drilling boreholes in anisotropic rock

Directional drilling is a viable and cost-effective trenchless technology for the installation of pipelines and conduits in shallow formations and the extraction of unconventional energy resources in deep reservoirs. The performance of drilled boreholes is associated not only with drilling practice...
