Abstract
The Abu Dhabi underground medium is composed by carbonate rocks, in such medium the seismic wave is highly attenuated and scattered during its propagation. In this abstract we determine robustly the total quality factor profile from Vertical Seismic Data(VSP) and also the scattering quality factor profile from the sonic log. The comparison between the two profiles shows that the scattering is bigger than the total attenuation, this is explained by the difference between the frequency range of the VSP(6-120Hz) and that of the sonic data(in order of mega Hz). The big values of the scattering indicate the large degree of heterogeneity in the medium.
