last reading

1. n. [Formation Evaluation]
The depth of the last reliable reading of a log. For the normal bottom-to-top survey, the last reliable reading often occurs just before the logging tool enters the casing. With several logging tools in a tool string, the last readings will be at different depths, depending on the measure point of each measurement.
Antonyms: first reading
