A drill bit assembly can include a bit body; sensor circuitry that includes a sensor for acquisition of sensor data; and a blade mountable to the bit body, where the blade includes a sensor circuitry recess for receipt of at least a portion of the sensor circuitry.

Instrumented drill bit

Methods and systems are disclosed that use a temperature sensor integral to a drill bit during drilling. The temperature sensor is configured to measure temperature associated with a cutting element of the drill bit over time during drilling. The temperature sensor is used to generate temperature data representing temperature of the cutting element of the drill bit over time during drilling. The temperature data is processed to determine and monitor at least one condition of the wellbore and/or the drill bit during drilling, such as i) detection of faults or openings or cracks or other geological rock features of the wellbore being drilled, ii) estimation of one or more drilling parameters of the drill bit (such as rate of penetration (ROP), iii) detection of lost cutting element(s), iv) detection of bit balling, and v) detection of drilling efficiency.

Temperature measurement at one or more cutting elements of a drill bit

A bit to detect drill bit metamorphism (DBM) may include a bit head. A bit to detect DBM may include at least one cutting element connected to the bit head. A bit to detect DBM may include a temperature sensor on or in the at least one cutting element. A bit to detect DBM may include an electronics module in communication with the temperature sensor. A bit to detect DBM may include a wiring conduit from the at least one cutting element and through at least a portion of the bit head to the electronics module.
