bottom log interval

1. n. [Formation Evaluation]
The bottom of the interval recorded on the log, or the deepest point at which the log readings are valid. At the bottom of the well, each log will have a valid first reading at a different depth. The bottom log interval is then either the lowermost first reading or the first reading of the most important log.
