Sucker rod and tubular identification and tracking

A method used for a tubular, the method comprising:

• providing a coupling for the tubular, the coupling having first and second ends, each of the first and second ends at least including internal thread and a counterbore area;
• applying an optically-coded machine-readable indicium to a surface on the counterbore area of the first end;
• and
• threading the internal thread of the second end of the coupling onto a pin end of the tubular.

A system used for threaded wellbore components configured to connect in an end-to-end assembly in a wellbore, the system comprising:

• a first database storing primary coded information associated individually with the threaded wellbore components, the primary coded information associated with indicia applied adjacent to threaded areas of the threaded wellbore components, the indicia being optically-coded and being machine-readable;
• a second database storing secondary coded information associated individually with the threaded wellbore components, the secondary coded information associated with machine-readable devices applied on thread protectors for use on the threaded areas of the threaded wellbore components;
• an input interface configured to obtain first read information read from the indicia and to obtain second read information read from the machine-readable devices;
• and
• a processing unit in operable communication with the first database, the second database, and the input interface, the processing unit being configured to:
• link the primary coded information to the secondary coded information;
• and
• track the threaded wellbore components based on the first and second read information relative to the linked primary and secondary coded information.
