Patent Images
1. A method of simulating drilling at least one portion of a wellbore using a rotary drill bit comprising:
- selecting a drilling mode from the group consisting of straight, kick off or equilibrium corresponding with the one portion of the wellbore;
inputting drilling equipment data including operational data selected from the group consisting of bit rotational speed, axial bit penetration rate and lateral bit penetration rate;
inputting wellbore data and formation data corresponding with the at least one portion of the wellbore;
applying a steer rate to the rotary drill bit as part of the simulation; and
simulating drilling the one portion of the wellbore using the drilling equipment data for the proposed set of drilling equipment, the wellbore data, and the formation data.

Abstract
Methods and systems may be provided for simulating forming a wide variety of directional wellbores including wellbores with variable tilt rates and/or relatively constant tilt rates. The methods and systems may also be used to simulate forming a wellbore in subterranean formations having a combination of soft, medium and hard formation materials, multiple layers of formation materials and relatively hard stringers disposed throughout one or more layers of formation material.
