NOV advances RIFD technology

Published by
Oilfield Technology,

National Oilwell Varco, Inc. has announced that it has introduced an advancement in Radio Frequency Identification (RFID) technology and asset management software for the oil and gas industry. Field testing for this latest generation RFID tag, TracTagTM, has proved the technology can withstand extreme drilling conditions when installed on drillstring components. The tag is currently the only RFID technology in the industry that can survive extreme downhole temperatures of -40°C to +200°C (-58°F to +400°F) and up to 1550 Bar (22’500 PSI) of pressure.

NOV has proved itself as a leader in using RFID for asset management on existing surface-based products and services; however, the technology behind TracTag has overcome the challenges associated with harsh downhole well conditions and can now be incorporated into NOV downhole products.

The company also introduced an asset management software, TracAssetTM, and an automated pipe tally system with a wellsite tag reader, AutoTallyTM. The combined system will enable greater capabilities for delivering reliable information and analysis to our customers.

Clay C. Williams, Chairman, President and CEO of National Oilwell Varco, stated:

“We continue to invest in new technologies that drive our industry forward and help our customers improve effective asset utilisation and reliability while decreasing their costs. The data we will be able to obtain from these innovative technologies will play a critical role in shaping the future development of drillstring components and tools.”

NOV will be capable of providing an entire lifecycle management solution for drillstring components that includes information regarding original manufacturing specifications, inspection and repair history, along with usage details. The TracTag and AutoTally system will make it possible to read tags as drillstring components pass through the rig floor; and integration of the system into the rig control system will provide drilling hours and critical drilling information down to the serial number of the component.

Incorporating the information into the global inspection and maintenance systems used by NOV’s Tuboscope Business Unit will provide customers with analytics and other detailed information about pipe inventory that the industry has not been able to collect in the past. NOV’s analytics enhance the lifecycle awareness of work history and associated inspections carried out which will mitigate instances of downhole tubular failure by knowing precisely when and where the tubular or downhole component has been used in a drilling environment in any given well.
