Azimuthal seismic reflection characteristics with quality factor Q in viscoelastic horizontal transverse isotropic media

Abstract In seismic exploration, a precise description of the reflection property is critical for reservoir prediction and fluid identification. study wave transmission effects, taking into account both viscoelastic anisotropic properties medium compatible with features earth. Moreover, it advantageous to characterization complicated reservoirs. According elastic foundation imaginary component quality factor Q, media are described in complex domain. The number expressed by phase velocity Q. attenuation angle introduced when represented propagation vector an vector. exact polarization direction using stiffness matrix incorporating Q elements. quasi-Zoeppritz equation horizontal transverse isotropic (VHTI) derived boundary conditions based on function media. numerical simulation reflectivity reveals that coefficient clearly different from medium. difference various orientations has distinct characteristics.
