Xplorer Tag From InfoChip and Xerafy Approved for Drill Pipes

InfoChip and Xerafy have announced that an independent study of the Xplorer tag—a rugged ultrahigh-frequency (UHF) RFID tag designed to be embedded in drill pipe and survive extreme downhole conditions—shows no detrimental impact to asset integrity when embedded in a drill pipe.

The Xplorer tag
The Xplorer, an ATEX-certified RFID tag encased in stainless steel, was developed in cooperation with oil and gas companies to provide drillers with an easy and accurate method of electronically identifying drilling pipe at distances as great as 5 feet, as it trips in and out of the well, the two companies explain. The tag is designed to reduce human error, ensure that the correct pipe is being deployed, collect and record data for advanced analytics, automate pipe tally, guide electronic field inspections, and perform many other tasks related to oilfield operations. Using the tag and fixed or handheld readers, the companies report, can help operators predict failure, increase the life of the pipe and reduce overall drilling cost.

InfoChip, which is the exclusive distributor of the Xplorer tag, announced that a finite element analysis (FEA) of the tag concludes that there is no detrimental impact to asset integrity when the tag is embedded in the tool joint of a drill pipe. T.H. Hill, the company that conducted the study, determined that "the pins of the connections had a lesser fatigue life than the RFID tag holes," according to InfoChip.
