Method for predicting drill bit wear

A system for a drill bit used in drilling for formation hydrocarbons, the system comprising:

• one or more processors;
• and
• a memory coupled to the one or more processors and storing instructions executable by the one or more processors to cause the system to:
• analyze a first three-dimensional (3D) scan of the drill bit generated through scanning before use and a second 3D scan of the drill bit generated through scanning after use to identify one or more wear characteristics of the drill bit based on the analysis;
• identify a drilling dysfunction present during use of the drill bit that produced the one or more wear characteristics;
• adjust at least one of penetration rate and torque in an adjustment of one or more drill operating parameters under which the drill bit is to be used;
• determine, using a model, that the adjustment produces one or more wear characteristics of the drill bit within a first threshold for acceptable drill bit wear;
• and
• adjust a well plan based on the determination;
• and
• control an operation of the drill bit based on the adjusted well plan to reduce the drilling dysfunction in drilling for the formation hydrocarbons.

A non-transitory computer readable medium comprising instructions executable by one or more processors to:

• analyze a first three-dimensional (3D) scan of a drill bit generated through scanning before use and a second 3D scan of the drill bit generated through scanning after use to identify one or more wear characteristics of the drill bit based on the analysis;
• identify a drilling dysfunction present during use of the drill bit that produced the one or more wear characteristics;
• adjust at least one of penetration rate and torque in an adjustment of one or more drill operating parameters under which the drill bit is to be used;
• determine, using a model, that the adjustment produces one or more wear characteristics of the drill bit within a first threshold for acceptable drill bit wear;
• adjust a well plan based on the determination;
• and
• control an operation of the drill bit based on the adjusted well plan to reduce the drilling dysfunction.
