Abstract
A tool includes a main body configured to be disposed within a tubular string within a wellbore, such that a location of the tool within the tubular string is changeable between a surface location and a downhole location. The tool includes one or more sensors configured to measure downhole parameters from which the physical properties of the wellbore can be determined. The tool further includes a flapper configured (a) to, in response to the position of the tool changing from the surface location to the downhole location, pivot radially from a closed position in which the flapper is aligned with the main body to an open position in which the flapper is away from the main body, and (b) to, in response to the position of the tool changing from the downhole location to the surface location, pivot radially from the open position to the closed position.
