Oilfield drill pipe UHF RFID application uses RFID technology to track oilfield drill pipes and pipelines to improve the accuracy of oilfield asset management and reduce oilfield accidents.
China Petroleum & Chemical Corporation Shengli Oilfield has turned to RFID technology for field testing to track downhole pipelines in its onshore oilfields. This use case is considered to be the first UHF RFID application in the oil and gas industry.
By embedding RFID tags on drill pipes, Shengli Oilfield can use UHF RFID handheld readers to track 1,380 drill pipes through seven websites provided by VictorySoft. In February of 2016, the pilot has been running for three months, and each well has opened about 2,500 meters.
Then Shengli Oilfield placed a well-centered antenna to read the tags. During the operation of lifting and lowering the pipe string, the RFID tag information was read. With the success of the UHF RFID application pilot for oilfield drill pipes, Shengli Oilfield will greatly expand the deployment of RFID tags to other drill strings and sites.
UHF RFID tag embedded in the drill pipe
Xerafy Xplorer’s UHF RFID tag is a patented UHF RFID tag made of high-strength steel and polymer, and is specifically designed to be embedded in the hole of the drill pipe joint to track each individual pipe. RFID technology is the key to achieving tasks that were previously impossible to track and capture data on various pipelines. Before adopting RFID technology, oil exploration and drilling companies often faced several problems. They cannot know exactly where the drill bit is, how it is used, and when it is used. During the drilling process, the drill rods used to construct the drilling rig unit are stored on the support of the rig or the support of the pipe yard. In order to find the correct components of the drill string in the structure, workers often need to climb on the drill pipe rack and measure the drill pipe with a tape measure. Next, the worker writes down the specifications on a piece of paper, and then manually enters the data into the computer. In some cases, they may also spray paint on the drill pipe to identify numbers, but this is of limited use. If the drill pipe mark on the bracket is in the wrong direction, or is covered by mud or worn out, then the incomplete mark will have no effect.
The ability to use RFID technology to track individual joints of drill pipe opens up new possibilities for improved documentation and process efficiency, thereby saving costs and reducing risks. Regulatory requirements, weather and operating conditions make China’s oil fields one of the most challenging asset management environments on the planet. During the operation of lifting and lowering the pipe string, the drill pipe is exposed to high temperature, extreme pressure and vibration, and chemical corrosion. The structure of Xerafy Xplorer RFID tags can reliably withstand downhole pressures up to 30,000 psi.
The Xplorer tag records important information such as ID number, steel number, size and weight, production information, final usage, and asset maintenance records. The stored information is transmitted to the RFID tracking system. By using handheld RFID readers, workers can obtain critical information before and after scanning all drill pipes, and can obtain real-time visibility when assets need cleaning and maintenance, and when they need to be scrapped.
This greatly reduces the risk of leaks and ruptures that may lead to detection failures. By collecting raw data in a timely manner, management can use field data to make quick and accurate decisions.
Xerafy CEO Dennis Khoo said: “The advantages of RFID tag solutions are undisputed for drilling, subsea and ground operations. “The more information services you get before pipeline equipment enters the well, the delay or catastrophe of an accident The less likely an accident is.
