METHOD AND APPARATUS FOR COLLECTING DRILL BIT PERFORMANCE DATA
First Claim
1. A drill bit for drilling a subterranean formation, comprising:
- a bit body bearing at least one cutting element and adapted for coupling to a drillstring;
a chamber formed within the bit body, the chamber configured for maintaining a pressure substantially near a surface atmospheric pressure while drilling the subterranean formation; and
one or more sensors disposed in the chamber and configured for sensing at least one physical parameter.

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.
