This discussion will focus on the importance of a Calibrated CBL with known casing responses with focus on API 10TR-1 evaluation techniques for Segmented Cement Bond (Radial) Tools. We will review several real life examples of bonding conditions that are regularly observed in SCVL identification logging situations as well as some techniques for using the acoustic response to get insight into potential gas storage behind casing.
