Modification and Performance Evaluation of Radio Frequency Identification Technology in High-Temperature and High-Pressure Environments

Summary As oil and gas exploration progresses into deeper and ultradeep territories, the radio frequency identification (RFID) tags used in drillpipes are required to demonstrate enhanced resilience to elevated temperatures and pressures. Current research on tags for ultrahigh temperature and ultrahigh pressure environments is relatively scarce. This study focuses on the application of RFID in deeper drilling operations, aiming to further enhance the tags’ temperature and pressure resistance to meet the application requirements. Numerical simulations were conducted to assess the mechanical properties of RFID tags installed on drillpipes of varying dimensions under conditions of elevated temperatures and pressures. This process enabled the optimization of the dimensions of the RFID tags and installation holes. The optimal dimensions for the RFID tag were determined to be φ24.3×7 mm, with the corresponding installation hole being φ24.3×11 mm. To evaluate the high-temperature endurance of the RFID tags, they were subjected to a temperature of 200℃ for a period of time, after which a maximum temperature of 230℃ was applied. Furthermore, a bespoke high-temperature and high-pressure apparatus was used to conduct a 7-day endurance test at 200℃ and 200 MPa. The findings demonstrated that the RFID tags exhibited reliable performance even when subjected to an extreme temperature of 230℃. Furthermore, the RFID tags exhibited consistent performance when subjected to prolonged periods of high temperature and pressure. The efficacy of the RFID tags was further validated through an 11-well field experiment, wherein the embedded tags exhibited no indications of detachment or deterioration. Once removed from the apparatus, the tags were able to be read automatically in real time, thus enabling the automated collection of data from the drillpipe in actual operating conditions. The findings of this study provide valuable insights and establish a foundation for the design and application of RFID tags in the challenging environments of deep and ultradeep oil and gas exploration.

A Reading Range- and Frequency-Reconfigurable Antenna for Near-Field and Far-Field UHF RFID Applications.

In radio frequency identification (RFID), differences in spectrum policies and tag misreading in different countries are the two main issues that limit its application. To solve these problems, this article proposes a composite right/left-handed transmission line (CRLH-TL)-based reconfigurable antenna for ultra-high frequency near-field and far-field RFID reader applications. The CRLH-TL is achieved using a periodically capacitive gap-loaded parallel plate line. By deploying the CRLH-TL operating at zeroth-order resonance, a loop antenna with in-phase radiating current is obtained, which contributes to a strong and uniform H-field and a horizontally polarized omnidirectional radiation pattern. By introducing additional tunable components, frequency and reading range reconfigurabilities are enabled. The frequency tuning range is from 833 MHz to 979 MHz, which covers the worldwide UHF RFID band. Moreover, each operation mode has a narrow frequency band, which means it can operate without violating different countries' radio frequency policy and reduce the design difficulty of designing multiple versions of a reader. Both the near-field interrogation zone and maximum far-field reading distance of the antenna are adjustable. The near-field interrogation zone is 400 mm × 400 mm × 50 mm and can be further confined. The tuning range for far-field reading distance is from 2.71 m to 0.35 m.

Metasurface loaded twin-port microstrip antenna with circular polarization features for UHF RFID applications

Abstract This communication designs and investigates a twin-port microstrip antenna loaded with a metasurface (MS). The proposed MS works in two ways: (i) artificial ground plane for radiator and (ii) as an ideal absorber of normal incoming waves at the same time. A stair shaped slot is loaded on rectangular patch for creating circularly polarized wave in between 835–894 MHz. Antenna port slots oriented in a mirror manner increase isolation by 25 dB. To act as a validation tool, the suggested antenna was built and its executions in individually operating modes evaluated by statistical and experimental analysis. It is shown that combining the patch and absorber results in a well-matched antenna in between 710–980 MHz with improved gain (more than 3.0 dBi). The proposed antenna design effectively used for UHF (Ultra High Frequency)radio-frequency identification (RFID) applications, which is due to its ability to mitigate multipath reflection issues and incorrectRFID reading.

Magnetic Permeability Perturbation-Based RFID Sensor for Pipeline Internal Corrosion Monitoring

Radio frequency identification (RFID) sensors for pipeline corrosion monitoring have been considered an attractive area due to the advantages of battery-free and maintenance-free. Due to the skin effect of high-frequency electromagnetic waves, existing RFID sensors can only detect the surface corrosion of pipelines. To realize internal corrosion monitoring, a magnetic permeability perturbation-based RFID sensing method was developed in this paper. Under direct-current (DC) magnetization, internal corrosion causes magnetic field distortions and incurs magnetic permeability perturbations in the skin layer of surface. These perturbations can be detected by the RFID sensor. Considering the resonance frequency shift (RFS) as a feature, a patch antenna sensitive to magnetic permeability was designed. Moreover, steel plates with artificial internal defects were simulated and tested to validate the feasibility of the proposed method. It was observed that the surface magnetic permeability perturbations caused by internal corrosions of different depths incur different RFS values. Finally, pipelines with artificial and natural internal corrosions were tested to validate the feasibility of the proposed method. The RFS caused by the natural corrosion was 4.26 MHz, and the RFS caused by the sound area was 1.63 MHz. The proposed magnetic permeability perturbation-based RFID method provides a promising method for pipeline internal corrosion monitoring with the application of RFID sensing technology.
