In one example, a method includes receiving acoustic cement evaluation data into a data processing system. The acoustic cement evaluation data derives from one or more acoustic downhole tools used over a depth interval in a well having a casing. The acoustic cement evaluation data includes sonic measurements and ultrasonic measurements. The method includes deriving a sonic-derived acoustic impedance Z(sonic) from the sonic measurements deriving an ultrasonic-derived acoustic impedance Z(ultrasonic) from the ultrasonic measurements comparing the Z(sonic) with respect to the Z(ultrasonic), and determining whether an annular fill behind the casing is well bonded, partially bonded, comprises wet microannulus, or comprises dry microannulus based on the comparison of the Z(sonic) with respect to the Z(ultrasonic)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cement evaluation using the integration of multiple modes of acoustic measurements","description":"Systems, methods, and devices for evaluating proper cement installation in a well are provided.
