正文 简介
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 landing indicator associated with the logging tool, and a sensor operatively associated with the logging tool. In use, the landing indicator generates a pressure pulse in the drilling tubular after contacting a travel restrictor positioned in the drilling tubular.
