This is a well log used in the oil and gas industry. You could find this abbreviation SPSD in your log evaluation software or any (ASCII) log files provided by the logging company. The official name for this log is 'SP from electrode sub processed downhole'. Usage of this log is not high and encountering it is a rare occasion. The values of this log represent the potential difference (DC voltage) between a movable electrode in the borehole and a distant reference electrode usually at surface. The voltage is due to currents generated by the Electrochemical and Electrokinetic potentials.This log usually has the unit 'Low Electric Potential'. Data from this log can be used to investigate the spontaneous potential of the formation. Similar logs are listed below:
