Abstract
Embodiments of the present invention provide methods, machines, and a computer medium or media having computer programs to determine presence anomalies in circumferential welds of one or more pipelines transporting fluids associated with energy therethrough. Wave form analysis or pattern recognition in pipeline data such as magnetic flux leakage data is employed. 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 machines, methods, and computer medium having computer programs can be used to screen for anomalies potentially threatening the structural integrity of the one or more pipelines so that site excavation can occur for confirmation and validation of the output results.
