Seismic Modeling With Complex Geology And Topography

Complex geology, due to folding and faulting, implying in strong lateral velocity variations and the rough<br>topographic relief are the principal constraints that may be faced in order to obtain a reliable subsurface seismic<br>image. Several physical investigations to support acquisition parameters and processing are on demand before<br>any new seismic acquisition in such area, in order to establish the best strategy to get a better subsurface<br>image. To perform this strategy we got information from several sources: geology, geophysics and modeling, in<br>the former we used finite difference acoustic and elastic wave propagation with topographic effects included<br>and ray tracing modeling, considering isotropic or smoothly inhomogeneous media. As a result of such<br>integration, we could investigate some acquisition parameters and processing steps which to have greater<br>impact on seismic data quality.
