...Background CP potentials in electrically connected multiple pipeline corridors are primarily determined through a conventional annual survey process that meets regulatory requirements. The Company supplements these efforts with enhanced system monitoring techniques such as Close Interval Potential...

... investigated is the portion of pipe sampled during a potential survey of a pipeline in a right-of-way containing multiple pipelines bonded to each other. As continuous potential surveys become used more often for analyzing pipeline conditions and cathodic protection (CP) effectiveness, understanding what...
