Patent abstract
A cement bond logging method for wells containing heavy mud and cement is provided. Acoustic logging tool data from a well having material in the annular space between the casing and the formation is analyzed to map relationships between waveform amplitude, acoustic impedance, and impedance derivative of the material. Map zones representing fully bonded well regions and partially bonded well regions are identified. An image is generated from the log data corresponding to the identified map zones. A cement bond logging system including a memory having cement bond logging software and a processor coupled to the memory to execute the software is also provided.
