AVO Modeling for the Effects of Attenuation and Random Scattering Using Thin-Slab Method

E-28 AVO MODELING FOR THE EFFECTS OF ATTENUATION AND RANDOM SCATTERING USING THIN-SLAB METHOD Abstract 1 The realistic geologic models may contain arbitrary spatial variations in compressional- and shearwave quality factors as well as in density and compressional- and shear-wave velocities. These heterogeneities may have different effects on the AVOs produced for homogeneous elastic models. Therefore efficiently modeling the effects of these heterogeneities is desirable for practical applications. In this paper we use the thin-slab method to model the effects of intrinsic attenuation variations elastic heterogeneities and their combinations on AVO responses. As examples we apply the method to three
