Abstract
Embodiments provide an expandable meshed component for guiding an untethered measurement device used in a subterranean well. The expandable meshed component includes an uphole radial portion, an intermediate radial portion, a downhole radial portion, an outer meshed wall, and an inner meshed wall. The expandable meshed component has a density less than a fluidic component occupying the space. A method for guiding an untethered measurement device used in a subterranean well includes deploying a compressed expandable meshed component tethered to the untethered measurement device, disconnecting the compressed expandable meshed component and the untethered measurement device, and releasing a sleeve surrounding the compressed expandable meshed component such that the expandable meshed component expands, ascends, and fits into an annulus.
