Abstract
An apparatus for evaluating an earth formation intersected by a wellbore may include a logging tool conveyed into the wellbore through a drilling tubular, a speed control device associated with the logging tool, and a sensor operatively associated with the logging tool. In use, the speed control device varies an annular flow space between the speed control device and a surface adjacent to control speed. The flow space may be varied using a annular member that flexes between a nominal diameter and a second larger diameter.
