Abstract
A method and system for cement evaluation. The method may include disposing an acoustic logging tool into a pipe string that is disposed in a first casing of a wellbore, transmitting an acoustic wave at a first location within the wellbore from an acoustic source disposed on the acoustic logging tool, and recording one or more acoustic signals with one or more receivers on the acoustic logging tool at the first location. The method may further include performing a multichannel multimode dispersion analysis of the one or more acoustic signals, extracting one or more fluid modes propagating in the first casing from the dispersion analysis, extracting one or more pseudo-lamb waves propagating in the first casing from the dispersion analysis, extracting one or more pseudo-SH-plate waves propagating in the first casing from the dispersion analysis, and identifying a bonding condition between the first casing and a cement.
