Abstract

A method of drilling a well using at least one drill bit and at least one secondary cutting structure, that includes determining a neutral point of a drill string positioning at least one secondary cutting structure based on the neutral point of the drill string, and drilling an earth formation.

Claims (11)

1. A method of determining an improved position of a secondary cutting structure used in a drilling tool assembly, comprising:

determining a neutral point of the drilling tool assembly;
modeling the drilling tool assembly having at least one secondary cutting structure at a first position;

simulating the drilling tool assembly;
moving a location of the at least one secondary cutting structure closer to the neutral point of the drilling tool assembly;
simulating the drilling tool assembly; and determining a location for the at least one secondary cutting structure based on the simulating.
2. The method of claim 1, wherein simulating the drilling tool assembly comprises outputting a graphical display of at least one of a lateral acceleration, torque on bit, torque or reamer, surface torque, rate of penetration, and a bending moment.
3. The method of claim 1, further comprising drilling a well with at least one drill bit and a secondary cutting structure located adjacent to the determined location.
4. The method of claim 1, wherein the at least one secondary cutting structure comprises a reamer.
5. The method of claim 1, wherein a determined location for the at least one secondary cutting structure is within 50 feet of the neutral point.
6. The method of claim 5, wherein the determined location for the at least one secondary cutting structure is within 5 feet of the neutral point.
7. A method of drilling a well using at least one drill bit and at least one secondary cutting structure, comprising:
determining a neutral point of a drill string;
positioning at least one secondary cutting structure based on the neutral point of the drill string; and drilling an earth formation.
8. The method of claim 7, wherein the positioning comprises placing the at least one secondary cutting structure within 60 feet of the neutral point.
9. The method of claim 8, wherein the positioning comprises placing the at least one secondary cutting structure within 30 feet of the neutral point.
10. The method of claim 9, wherein the positioning comprises placing the at least one secondary cutting structure within 10 feet of the neutral point.
11. A method of selecting a weight on bit for a drilling application, comprising:
determining, for a given drill string design, a neutral point based on a first weight on bit;
determining; for the given drill string design, a neutral point based on a second weight on bit;
selecting a weight on bit, based on the first and second weight on bits, that places the neutral point of the drill string adjacent a secondary cutting structure.
