Abstract:
Techniques for analyzing operation of drill bit in a borehole are disclosed herein. A method for analyzing operation of a drill bit in a borehole includes providing information describing the drill bit and a bent housing coupled to the drill bit. A path of a cutter of the drill bit is determined based on a ratio of a rotational speed of the bent housing to a combined rotational speed of the drill bit and the bent housing. The combined rotational speed is different from the rotation speed of the bent housing.
