TECH DATASHEET

Pipeline Survey Modes

STAB SURVEY

The stab survey method records the actual steel potential with periodic stabs every 1 - 3 km. The potential between stabs can be accurately calculated with pipeline attenuation modeling. Deep C Meter software in Stab Survey mode records events and exports a completed survey for the engineers to model.

REMOTE ELECTRODE SURVEY

The remote electrode method calibrates a remote reading with periodic stabs of bare steel along the pipeline.  The data is then aligned in post processing.  Not as accurate as a stab survey, but required in some regions. Deep C Meter software in Remote mode outputs stab events and the complete set f readings from the proximity electrode for processing.
