Remote field eddy current test combined with additional eddy current test, for tubular components

摘要

The non-destructive testing of electrically conductive components such as wellbore tubulars, which is suitable for testing the components in situ a wellbore installation is done with remote field eddy current test (RFET) phase subsystem 200 and at least one of a conventional eddy current test phase and a partial saturation eddy current test phase by subsystem 100. A measurement dataset from each of the test phases is obtained and the combined measurement data is processed to evaluate a condition of the tube or pipe. Umbilical 12 may be used to relay data to a platform. Also included is electronics subsystem 300.
