Monitoring drilling conditions and estimating rock properties

A system comprising:

• a drill bit comprising:
• a shank;
• a bit body connected to the shank;
• and
• one or more blades connected to the bit body;
• a sensor package disposed on the drill bit, wherein the sensor package is disposed in a recessed area of the shank in an exterior of the drill bit, wherein the sensor package is configured to:
• measure one or more drill bit responses within a depth interval;
• and
• an information handling system in communication with the sensor package, wherein the information handling system is configured to:
• identify one or more torsional bit vibrations within the depth interval from the one or more drill bit responses;
• determine one or more bedding layers of a formation within the depth interval from the one or more torsional bit vibrations;
• and
• identify a confined compressive strength (CCS) for each of the one or more bedding layer using the one or more drill bit responses and the one or more torsional bit vibrations.

A system comprising:

• a drill bit comprising:
• a shank;
• a bit body connected to the shank;
• and
• one or more blades connected to the bit body;
• a sensor package, wherein the sensor package includes at least one insert that is secured, via threading and/or compression, within a recessed area formed in the drill bit, wherein the sensor package is configured to:
• measure one or more drill bit responses within a depth interval;
• and
• an information handling system in communication with the sensor package, wherein the information handling system is configured to:
• identify one or more torsional bit vibrations within the depth interval from the one or more drill bit responses;
• determine one or more bedding layers of a formation within the depth interval from the one or more torsional bit vibrations;
• and
• identify a confined compressive strength (CCS) for each of the one or more bedding layers using the one or more drill bit responses and the one or more torsional bit vibrations.
