Drilling a horizontal well in the Middle Bakken Formation (normal stress regime), 3. (a) What is the most favorable direction for wellbore trajectory, with respect to the direction of the in-situ stresses, from wellbore stability point of view? Support your answer by providing a simple numerical example. (5.0 marks) propagation of the fracture with respect to the wellbore trajectory. (3.0 marks) (sides or top and bottom) we expect to observe shear failures? Explain why. (2.0 marks) (b) If hydraulic fracturing...
