Abstract: Identification and tracking of sucker rods, tubulars, and other threaded wellbore components uses a coded indicium or a distinctive marking adjacent threaded areas, such as on the pin ends of the endpieces for the sucker rods or on the counterbore of a tubular coupling. The coded indicium can be applied to a surface of an undercut area located on the pin end between a threaded area and a shoulder of the endpiece. The coded indicium is applied with a non-damaging process, such as laser annealing, laser marking, or another comparable technique. When the endpieces are connected together with a coupling, the coded indicium in the undercut area is covered by the coupling, which threads to the pin ends and engages the shoulder of the endpieces. Secondary tracking can also be achieved using an electronic device, such as an RFID device, disposed on a thread protector for the threaded wellbore component.
