Abstract: A method and system for inspecting casings in a wellbore to determine a mechanical or sealing quality of casing connections. Casing connections may become mechanically weak or start to leak after some period of use in harsh conditions. A radial array of ultrasound transducers images the casing in-situ to create an ultrasound image, which is analyzed to detect the casing connector then analyzed a sealing band of the connector. Machine learning and image processing methods may be used to analyze the images.
