X-Change Corp rolls out oil country RFID tags

New surface acoustic wave technology maximizes read range for oil field equipment tags.

X-Change Corporation unit AirGate Technologies is now rolling out surface acoustic wave (SAW) tag technology based on radio frequency identification (RFID) that is tailored for use on oil country tubular goods. SAW tags and readers are used for monitoring drill pipe and other down hole tools.


Tags are inserted into drill pipe to determine pedigree, asset and inventory in down-hole drilling environments. Tags and readers can survive the lifetime of the pipe or tool. SAW technology uses on-chip digital signal processing to broadcast a unique identifier when polled.


AirGate president Kathleen Hanafan explained, ‘The tags have been developed to withstand temperatures up to 300°C and pressures up to 20,000 psi. They also offer the long read range that is needed in oil industry.’
