Abstract:
A cutting element for a drill bit is advanceable into a subterranean formation to form a wellbore. The cutting element includes an element body having a face at an end thereof, and a ridge. The element body has a face at an end thereof. The face has a ramp and a pair of side regions thereon. The ramp has a curved edge along a periphery of the face and two sides. Each of the two sides extends from opposite ends of the curved edge and converges at a location along the face. The face has a chamfer along a peripheral edge thereof. The ridge is between the chamfer and the location. Each of the pair of side regions is positioned on opposite sides of the ridge and extends between the periphery, the ridge, and one of the two sides of the ramp whereby the chamfer engages a wall of the wellbore and extrudate is drawn along the pair of side regions.
