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.
