    Cement bond logging (CBL) is an important part of a well-completion program and is also recommended for most workover programs. Most of the cementing-related problems encountered can be diagnosed by use of the CBL. However, successful interpretation of a CBL depends on certain minimum requirements:

    What is Cement Bond Log (CBL)? - Definition .

    A cement bond log (CBL) is a means to determine the integrity and quality of a cement bond. After a borehole is drilled, the casing is lowered and cement slurry is injected into the annulus between the casing and the borehole wall. The cementing is done to ensure that the casing is well supported and fluid is prevented from finding it way to the surface. Cementing is also done for other ...

    CEMENT BOND LOG INTERPRETATION:

    No cement bond "zero bond" or "free pipe" is represented by maximum amplitude. Due to the fact that well cemented pipe can never reduce the signal to "zero", a good reference for 100 percent bond is the best cemented portion of the cemented cased hole. Formation - Cement bond: Using information obtained from a Variable Density (waveform) display referred to as a VDL display, it is ...
