The most important thing for the Petrobras is to monitor the rig and the machines during the drilling. Furthermore, the technicians can read the tags with readers in order to store a record of what is being loaded. The reader captures each tag's unique ID number, and transmits that information to Trac ID's Asset Management System (TAM) software running on Weatherford's back-end server, via a Wi-Fi connection to the Internet or a GPRS connection.
According to the tag's ID number, the TAM software retrieves data related to that pipe and forwards it to the handheld reader so that employees can immediately view details about the pipe and receive an alert if it is due for an inspection or requires maintenance. The typical problems during the drilling for instance the drill can wear away a pipe's exterior, and if the reduction in diameter is severe enough, a pipe must be repaired or replaced.
At the same time the unique and doubted part of the RFID systems is its early stages. 7,500 drill pipes are expected to be tagged by the end of 2010. Weatherford highly believes that providing relevant, technical, inspection and usage data almost immediately will attract more an more clients.
The Trac ID RFID tags attached to the drill pipe are able to read automatically inside oil wells.
