Abstract
A logging apparatus for use in a well can include at least one sensor that senses a well parameter, at least one buoyancy control device, and the logging apparatus extending helically between opposite ends of the logging apparatus. A method of logging in a subterranean well can include installing at least one logging apparatus in the well, and the logging apparatus helically displacing in the well as a sensor of the logging apparatus senses a well parameter. A well system can include at least one logging apparatus disposed in a wellbore, the logging apparatus including multiple segments, the segments including at least one buoyancy control device and at least one sensor that senses a well parameter, and the segments being helically arranged in the wellbore.
