Abstract
An acoustic logging tool traverses a fluid-filled cased well with an asymmetric acoustic energy transducer. Pressure waves created in the well fluid by the transducer generate asymmetric tube waves in the well casing. At least one spaced-apart transducer receives these asymmetric tube waves after they have traveled directly to the receiver through the well casing. Changes in tube wave ampltiude as detected by the receiver are used to identify the azimuth and height of any fracture interval in the formation behind the well casing.
