METHOD AND APPARATUS FOR COLLECTING DRILL BIT PERFORMANCE DATA
First Claim
1. A method, comprising:
- collecting sensor data at a sampling frequency by sampling at least one sensor disposed in a drill bit, wherein the at least one sensor is responsive to at least one physical parameter associated with a drill bit state;
analyzing the sensor data to develop a severity index, wherein the analysis is performed by a processor disposed in the drill bit;
comparing the severity index to at least one adaptive threshold; and
modifying a data sampling mode responsive to the comparison.

Abstract
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, analyze the sensor data to develop a severity index, compare the sensor data to at least one adaptive threshold, and modify 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.
