Abstract:
A cutter profile for a fixed cutter drill bit having a drill bit axis. The cutter profile includes a nose portion radially offset from the drill bit axis and surrounding the drill bit axis, a first cone-shaped depression centered on the drill bit axis and extending radially to the nose portion, and a second cone-shaped depression centered on the drill bit axis and extending radially toward the nose portion. A second depression diameter is smaller than a first depression diameter. A second depression maximum depth is greater than a first depression maximum depth. A second depression included angle is smaller than a first depression included angle.
