ULTRASONIC LOGGING METHODS AND APPARATUS FOR MEASURING CEMENT AND CASING PROPERTIES USING ACOUSTIC ECHOES

A method and apparatus for measuring parameters of a borehole using an acoustic logging system. By transmitting a high frequency acoustic signal essentially perpendicular to the major axis of a borehole casing using a transducer, the high frequency acoustic signal may produce one or more acoustic ec...
