Fluid losses leading to severe technical issues
Mud pressure higher than minimum principal stress around the borehole inducing losses of drilling fluid, slurry or treatment fluid containing solid particles into the formation. This can lead to reservoir damages and/or drilling blind with no cutting coming up anymore to gives information on the formation encountered
