Areas of probable pipeline rupture have been identified by continuous pipe-to-soil potential profiles. This method of testing and evaluation forms an integral part of many corrosion control programs for transmission pipelines. Cathodic protection monitoring and location of pipeline anomalies are results of continuous potential logging. The survey technique detects localized, active corrosion due to a variety of causes. Areas which do not comply with the pipe-to-soil potential criterion for cathodic protection are also identified. The use of microcomputer systems for data collection and processing allows for accurate measurement and new methods of analyses which were not previously practical.
