..., there is no direct way to determine the orientation and the magnitude of the maximum hori- zontal stress H and the in situ rock strength. The location of wellbore failure is governed by the in si- tu stress state and the orientation of the wellbore, while the occurrence of wellbore failure is also de- pendent...
