Patent number: 11029283Abstract: A technique facilitates examination of a tubing string. A sensor is mounted to monitor a pipe for a defect or defects. The sensor outputs data on the defect to a data processing system which identifies the type and severity of the defect. The data processing system also may be used to track the defect to determine changes to the defect during, for example, subsequent uses of the pipe. Based on the evaluation of the defect, recommendations are provided with respect to future use or handling of the pipe.Type: GrantFiled: October 3, 2014Date of Patent: June 8, 2021Assignee: Schlumberger Technology CorporationInventors: Shunfeng Zheng, Zhanke Liu

Patent number: 10883966Abstract: A technique facilitates examination of a tubing string which may comprise coiled tubing or other types of pipe. A sensor is positioned to monitor a pipe for a magnetic flux leakage signal indicating a defect in the pipe. The sensor outputs data on the magnetic flux leakage signal to a data processing system. Correlations between magnetic flux leakage signals and fatigue life of the pipe may be accessed by the data processing system and these correlations may be used to automatically predict a fatigue life of the pipe. Based on the determined fatigue life, an operation with respect to the pipe is selected and such operation may comprise continued normal use, repair, or removal from service.Type: GrantFiled: June 4, 2015Date of Patent: January 5, 2021Assignee: Schlumberger Technology CorporationInventors: Shunfeng Zheng, Zhanke Liu

Patent number: 10877000Abstract: A technique facilitates prediction of run life. Data relating to a pipe defect is provided to a data processing system for comparison to stored data regarding defects. Additionally, data regarding fatigue life accumulation is stored on the data processing system as it relates to fatigue life of the pipe based on the number of cycles to failure of the pipe without the presence of the defect. The number of cycles experienced by the pipe at the time the defect occurs in the pipe also is determined and provided to the data processing system. The system and methodology further comprise using the data regarding the defect type, the fatigue life accumulation data for the pipe, and the number of cycles experienced by the pipe at the time of the defect to estimate a remaining number of cycles until failure of the pipe.Type: GrantFiled: December 8, 2016Date of Patent: December 29, 2020Assignee: Schlumberger Technology CorporationInventors: Zhanke Liu, Michael Hayes Kenison, Gregory Campbell

Patent number: 10444188Abstract: A technique facilitates monitoring of pipe, such as coiled tubing. The monitoring may be used to detect conditions which occur within the pipe itself or in components employed along an interior of the pipe. A magnetic sensor system is positioned along an exterior of the pipe, e.g. coiled tubing. During relative movement between the pipe and the magnetic sensor system, the magnetic sensor system monitors for the condition, e.g. change/abnormality, of interest. In some applications, the magnetic sensor system is used to monitor changes in a physical property of the pipe, and/or a component within the pipe, during a succession of operations employing the pipe.Type: GrantFiled: October 1, 2013Date of Patent: October 15, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Mirjam Zwanenburg, David P.
