Method and apparatus for collecting drill bit performance data
View Patent ↗Drill bits and methods for sampling sensor data associated with the state of a drill bit are disclosed. A drill bit for drilling a subterranean formation comprises a bit body and a shank. The shank further includes a central bore formed through an inside diameter of the shank and configured for receiving a data analysis module. The data analysis module comprises a plurality of sensors, a memory, and a processor. The processor is configured for executing computer instructions to collect the sensor data by sampling the plurality of sensors, analyzing the sensor data to develop a severity index, comparing the sensor data to at least one adaptive threshold, and modifying a data sampling mode responsive to the comparison. A method comprises collecting sensor data by sampling a plurality of physical parameters associated with a drill bit state while in various sampling modes and transitioning between those sampling modes.
1. A method, comprising:
collecting background data by sampling at least one physical parameter associated with a drill bit state at a background sampling frequency while in a background mode; and
transitioning from the background mode to a logging mode after a predetermined number of background samples to sample the at least one physical parameter at a logging sampling frequency higher than the background sampling frequency.
2. The method of claim 1 , further comprising storing the background data in memory.
3. The method of claim 1 , further comprising:
collecting logging data by sampling the at least one physical parameter at the logging sampling frequency while in the logging mode; and
transitioning from the logging mode to the background mode after a predetermined number of logging samples.
4. The method of claim 3 , further comprising storing the logging data in memory.
5. The method of claim 1 , further comprising:
collecting logging data by sampling the at least one physical parameter at the logging sampling frequency while in the logging mode; and
transitioning from the logging mode to a burst mode after a predetermined number of logging samples to sample the at least one physical parameter at a burst sampling frequency higher than the logging sampling frequency.
6. The method of claim 5 , further comprising storing the logging data in a memory.
7. The method of claim 5 , further comprising:
collecting burst data by sampling the at least one physical parameter at the burst sampling frequency while in the burst mode; and
transitioning from the burst mode to the background mode after a predetermined number of burst samples.
8. The method of claim 7 , further comprising storing the burst data in a memory.
9. The method of claim 5 , further comprising:
collecting burst data by sampling the at least one physical parameter at the burst sampling frequency while in the burst mode; and
transitioning from the burst mode to the logging mode, after a predetermined number of burst samples.

11. A method, comprising:
collecting background data by sampling at least one physical parameter associated with a drill bit state at a background sampling frequency while in a background mode; and
transitioning from the background mode to a burst mode after a predetermined number of background samples to sample the at least one physical parameter at a burst sampling frequency higher than the background sampling frequency.
12. The method of claim 11 , further comprising storing the background data in memory.
13. The method of claim 11 , further comprising:
collecting burst data by sampling the at least one physical parameter at the burst sampling frequency while in the burst mode; and
transitioning from the burst mode to the background mode after a predetermined number of burst samples.
14. The method of claim 13 , further comprising storing the burst data in memory.
15. The method of claim 11 , further comprising:
collecting burst data by sampling the at least one physical parameter at the burst sampling frequency while in the burst mode; and
transitioning from the burst mode to a logging mode after a predetermined number of burst samples to sample the at least one physical parameter at a logging sampling frequency lower than the burst sampling frequency.
16. The method of claim 15 , further comprising storing the burst data in memory.
17. The method of claim 15 , further comprising:
collecting logging data by sampling the at least one physical parameter at the logging sampling frequency while in the logging mode; and
