By drilling a well, i.e. removal of a cylinder of rock from the subsurface, a disturbance of the natural stress state is created. Where the horizontal stresses are strong and unequal, then the borehole will be subjected to an imbalanced horizontal stress condition. Drilling mud is weighted to create...
