Abstract
An apparatus for forming a wellbore in a formation may include a bit body and a sensor in the bit body. The sensor may include at least one cutting element and may be configured to generate information relating to a parameter of interest when the drill bit engages a wellbore surface.
Claims14
A drill bit, comprising:
- a bit body;
- and
- a sensor in the bit body, the sensor including at least one cutting element, the sensor being configured to generate information related to at least one of a pressure, a strain and a temperature of the cutting element in response to transfer of a motion of the at least one cutting element to the sensor when the at least one cutting element engages a wellbore surface.
A drill bit, comprising:
- a bit body;
- a sensor in the bit body, the sensor including at least one cutting element and a sensing element operatively coupled to the at least one cutting element, the sensor being configured to generate information related to at least one of a pressure, a strain and a temperature of the cutting element in response to transfer of a motion of the at least one cutting element to the sensor when the at least one cutting element engages a wellbore surface;
- a controller configured to operate the sensor;
- and
- a communication device configured to provide signal communication between the controller and the sensor.
