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. After the logging tool is positioned at the target depth, the sensor makes at least one measurement while the logging tool is in the drilling tubular and provides an output indicative of a selected subsurface parameter. |
