Abstract
Embodiments of the present invention provide systems, methods, and computer medium having computer programs to determine presence of stress corrosion cracking in one or more pipelines or portions thereof such as pipeline joints by utilizing pattern recognition in pipeline data such as magnetic flux leakage data. A screening process, for example, does not affect or change how survey data is recorded such as in survey tools; only how it is analyzed after the survey data is completed. Embodiments of the systems, methods, and computer medium having computer programs can be used to screen for potential locations of stress corrosion cracking in one or more pipelines so that site excavation can occur for confirmation and validation of the output results.
