13 Introduction Near surface example P velocity distribution (a) P velocity distribution (b) Density distribution (c) S velocity distribution (d) Figure 1 Distributions of velocities and densities obtained by seismic surveying Near surface example (a), petroleum type example (b, c, d) • The third chapter is about full waveform acoustic logging and its main applications in the civil engineering field. It briefly describes: the logging tools implemented (monopole or dipole), the different wave types that make up acoustic recordings, and the contribution of acoustic measurements to the description of geological formations (mechanical parameters). There is also a discussion on the contribution of Stoneley waves for the estimation of S velocities of formations
