n: an electric log in which current flow in the logging tool was dispersed through the mud in the wellbore prior to entering the formation. As a result, formation resistivity measurements were often inaccurate. These logs are no longer used.

n: in conventional electric logging. the curve drawn on the log by a device on an electric logging tool that is designed to measure formation resistivity about 36 feet (11 metres) from the wellbore.

n: a resistivity curve made by a conventional electric logging device.

n: see conventional electric log.

n: in conventional electric logging, measures resistivity in the formation only a short distance from the borehole. Used for shallow investigation of the formation.

n: in conventional electric logging, measures resistivity in the formation a long distance from the borehole. Used for deep investigation of the borehole.

n: see conventional electric log.
