A system, device and method for imaging, measuring and identifying surface features in a tubular, such as a casing, wellbore, or pipe. The device comprises an ultrasound transducer for sonifying an area of the surface of the tubular, with a pulse intercepting axial locations of the sonified area at different times. Reflected signals are processed using their time of flight to interpret the reflected signals as axial locations of features on the surface of the tubular. Multiple sonified areas are partially overlapped in the axial direction to capture features redundantly. Reflections from the multiple areas are combined to remove noise and strengthen reflections from real features. A geometric model of the surface of the tubular is rendered and displayed. Capturing larger areas per frame increases the logging rate and oversampling improves the resolution and signal to noise ratio.

Systems and methods are provided for obtaining a flexural-attenuation measurement for cement evaluation that may be effective even for wells with relatively thick casings. A method includes emitting an acoustic signal at a casing in a well that excites the casing into generating an acoustic response signal containing acoustic waves, such as Lamb waves. The Lamb waves include flexural waves and extensional waves. The casing may be relatively large, having a thickness of at least 16 mm. The acoustic response signal may be detected and filtered to reduce a relative contribution of the extensional waves. This may correspondingly increase a relative contribution of the flexural waves. The filtered acoustic response signal may be used as a flexural-attenuation measurement for cement evaluation.
