Comparison of finite-difference and ray-theory seismograms in the elastic SEG/EAGE Salt Model, shot number 145

Vaclav Bucha

Summary

Finite-difference seismograms for a selected shot and two receiver configurations computed in the elastic SEG/EAGE Salt Model during the Next-Generation Seismic Modeling and Imaging project are compared with ray-theory seismograms calculated using the SW3D software. Two-point rays of direct, refracted and reflected P-waves and converted S-waves in the smoothed elastic SEG/EAGE Salt Model are computed.

Keywords

Elastic velocity model, ray tracing, seismic waves, synthetic seismograms.
