TRANSITIONAL DRILLING CHALLENGE
One of the biggest challenges facing the drilling industry is interfacial severity, or transitional drilling. This is broadly defined as layers of rock with different hardness that require the bit to drill through the transition, putting cutting forces on different parts of the profile. The imbalance of force concentration can induce vibration or even cause cutter overload, both of which lead to severe cutting structure damage.
