ABSTRACT:
A method and apparatus for retrieving logging data from a downhole logging tool is presented. The tool includes a plurality of sensors which acquire data which is stored in memory. Upon receiving an appropriate signal from a surface control unit, the logging tool transmits the logging data from memory. This can be accomplished when drilling has paused; for example, while the well is being conditioned.
