Principle objective of this lecture is to present on Acoustic Log. Acoustic tools measure the speed of sound waves in subsurface formations. While the acoustic log can be used to determine porosity in consolidated formations, it is also valuable in other applications, such as: Indicating lithology (using the ratio of compressional velocity over shear velocity), Determining integrated travel time (an important tool for seismic/wellbore correlation), Correlation with other wells; Detecting fractures and evaluating secondary porosity etc.
