Zusammenfassung:	A system including a casing string having one or more casing segments, a logging tool, and one or more float valves. The casing string can have a distal end and a proximal end with the logging tool detachably coupled with the distal end thereof. The one or more float valves can be coupled with a distal end of the logging tool. The logging tool can have a battery power source transitionable between a standby power mode and a full power mode. The casing string is operable to be disposed in a wellbore and transition the logging tool from the standby power mode to the full power mode upon placement within a predetermined portion of the wellbore.
