  • Method of removing cutters
    Patent number: 9027643
    Abstract: A method for enhanced degradation of a cutting structure on a drill shoe is provided. The cutting structure may be degraded at an accelerated rate after achieving a desired objective. Degradation of the cutting structures on the drill shoe may facilitate the eventual drill out of the drill shoe. In one embodiment, a method of degrading the cutting structure includes operating the drill shoe using a reduced flow rate of drilling fluid. In another embodiment, a method of degrading the cutting structure includes operating the drill shoe at an increased rotary speed. In yet another embodiment, a method of degrading the cutting structure includes operating the drill shoe with an increased weight on bit. In yet another embodiment, a method of degrading the cutting structure includes any combination of one or more of the enhanced degradation methods described herein.
