Joint inversion of seismic reflection traveltimes and wave polarizations for anisotropic parameters using simulated annealing: a modeling study
Chen, J., 2011. Joint inversion of seismic reflection traveltimes and wave polarizations for anisotropic parameters using simulated annealing: a modeling study. Journal of Seismic Exploration, 20: 91-104. It is very important to utilize as much information as possible to constrain the solution due to the non-unique solutions of seismic inversion. In this paper, a joint inversion scheme of seismic reflection traveltime and wave polarization data is proposed to determine three of the five anisotropic parameters (vertical P-wave velocity vps and Thomsen’s parameters 8 and 6) in transversely isotropic media with a vertical symmetry axis (VTI). The shooting ray tracing method is applied to the forward model to obtain the seismic reflection traveltimes and polarizations. The numerical tests demonstrate that the joint inversion method can provide a better constrain to the anisotropic parameters than other inversions using single dataset (traveltime or polarization).
