Description
A-One Oil Cement Bond Log Tool is an acoustic logging tool. It evaluate the bonding quality between the casing and cement sheath as well as between the cement sheath and the formation. By transmitting acoustic signals and receiving reflected signals from different paths, it determines the integrity of cement bonding.
The CBL includes a 3-foot sector receiving probe, and a 5-foot VDL (Variable Density Log) probe. Each sector covers a 45° cross-section, allowing for a 360° assessment of the cement bond integrity.
