Corrected Phase Shift DOWN (CPDO) |
This is a log of measurements along a well bore (a well-log). You could find this abbreviation CPDO in your log evaluation software or any (ASCII) log files provided by the logging company. Corrected Phase Shift DOWN is the full name for this log. This log is not often acquired after (or during) drilling a well. This log can be used to evaluate the result of adding or subtracting from a phase measurement. In general this log thus reflects units of the plane angle. This can be explained as being the angular displacement between two lines extending from the same point, measured in the plane of the two lines.This log in unitless. Either the log measurements can not be expressed with a unit (eg. a ratio) or the unit is unknown to us. Data from this log can be used to investigate the phase shift. Similar logs are listed below:
