Items of equipment and assemblies for use in drilling or completion of a
well or in other well operations are monitored from the time they are
assembled for shipment to a particular well site for a job through the
time of delivery and installation at the well site. Radio frequency
identifier devices (RFID's) are mounted with the items to electronically
tag them as they are assembled for shipment. The items are assembled into
containers which can be readily inventoried during transit to detect loss
or pilferage. Detailed information about the individual items can be
encoded into the RFID at the time of electronic tagging. If desired, the
shipping containers can be provided with separate RFID's detailing the
particular items within the container and the progress of the shipment
monitored remotely by satellite or the like.
