Abstract

A method for selecting at least one drill bit that includes characterizing an application; checking for at least one drill bit with an equivalent characterization in a data store; when the at least one drill bit with the equivalent characterization exists, selecting the at least one drill bit with the equivalent characterization; and when the at least one drill bit with the equivalent characterization does not exist, recommending at least one drill bit, making an analysis request, analyzing the at least one recommended drill bit based on the analysis request, generating analysis results, and selecting at least one drill bit based on the analysis results is disclosed.

Claims (28)

1. A computer assisted method for selecting at least one drill bit, the method comprising:

characterizing an application; checking for at least one drill bit with an equivalent characterization in a data store; when the at least one drill bit with the equivalent characterization exists,

selecting the at least one drill bit with the equivalent characterization; and

when the at least one drill bit with the equivalent characterization does not exist, recommending at least one drill bit, making an analysis request, analyzing the at least one recommended drill bit based on the analysis request,

wherein analyzing comprises simulating the at least one recommended drill bit based on information provided by the analysis request, generating analysis results, selecting at least one drill bit based on the analysis results, and

modifying the data store by storing the analysis results in the data store,

wherein the at least one recommended drill bit is determined concurrently when checking for the at least one drill bit with equivalent characterization in the data store.

2. The method of claim 1 , further comprising:

determining drilling application need, wherein the characterizing an application is based on the drilling application need.

3. The method of claim 1 , further comprising:

obtaining field performance information on the at least one selected bit, wherein the performance information is stored in the data store.

4. The method of claim 1 , further comprising:

storing the analysis results in the data store.

5. The method of claim 1 , further comprising:

conducting a peer review of the application characterization and the analysis request, wherein

when the application characterization is determined to be unacceptable in peer review, the application is recharacterized, and

when the analysis request is determined to be unacceptable in peer review, a revised analysis request is made.

6. The method of claim 1 , wherein the at least one recommended drill bit is determined using a drilling optimization service.

7. The method of claim 6 , wherein the simulating the at least one recommended drill bit is further based on information stored in the data store.

8. The method of claim 1 , wherein the analysis request comprises well profile information and drill string information.

9. The method of claim 8 , wherein the analysis request further comprises originator, location information, recommended drill bits, and drilling parameters.

10. The method of claim 1 , wherein characterizing an application comprises characterizing bottom hole assembly, formation, drilling parameters, and well profile.

11. The method of claim 1 , further comprising:

creating a peer review presentation on the at least one selected drill bit.

12. The method of claim 1 , further comprising:

outputting at least one of the analysis results and the selected drill bit.

13. The method of claim 1 , further comprising:

drilling a well with the selected drill bit.
