Abstract
A system for determining a location and a diameter of a pipe deployed in a bore includes a plurality of circumferentially spaced acoustic transmitters and a plurality of circumferentially spaced acoustic receivers deployed in a wall of the bore. A processor is configured to identify and process received acoustic waveforms that are reflected by the pipe to compute the location and the diameter of the pipe. The system may include a drill string deployed in a drilling riser.
