To complement the now traditional Cement Bond Log (CBL/VDL), a device called CET (Cement Evaluation Tool) was commercially introduced in 1982. It features an array of eight ultrasonic transducers allowing a radial inspection of the casing and its annulus. Its response can be interpreted in terms of cementation quality. In particular, distinction between acceptable cement, unset slurry or liquid, gaseous cement and free gas can be made. Analysis of the radial and vertical distribution of the materials located by the device provides the basis for the identification of possible causes of poor cementation. With these indications primary cementing procedures can be controlled and improved. Also, remedial cementing methods can be more rigorously adapted to individual situations.
