Abstract: Systems and methods include a method for using a downhole logging tool. A downhole logging tool is inserted into a well. The downhole logging tool includes a gauge chamber containing gauges, a compressed gas chamber containing compressed gas, a timer powered by a battery, a release sub, and a balloon housing containing a balloon in a deflated state. Data is collected by the gauges of the downhole logging tool during a downward travel of the downhole logging tool. A release point to release compressed gas is determined by the timer based on a travelling speed of the downhole logging tool. The compressed gas is released by the release sub at the release point, inflating the balloon to an inflated state, creating a buoyant force for the downhole logging tool. Additional data is collected by the gauges of the downhole logging tool during an upward travel of the downhole logging tool.
