In addition, the ultrasonic cement impedance measurement and the CBL-VDL (in combination) identify clearly the cement bond conditions. This combination provides comprehensive well mechanical integrity interpretation of the well. New 3D visualization capabilities of caliper, magnetic flux-leakage, and ...
