... flexural wave attenuation, mitigating the interference, and providing a reliable cement bond evaluation. In the 1960s, low-frequency sonic measurements, like the cement-bond log/variable-density log (CBL/VDL), were introduced, operating at around 20 kHz. These modalities remain relevant today due...
