Abstract

Macro models are the basis for any wave field extrapolation or migration proces. The accuracy with which to define such a macro model depends on whether one would like to obtain only structural information or whether one would like to use amplitude information as well in order to extract lithologic information. In case of the latter it is important to estimate macro boundaries as accurate as possible to minimize the influence of angle dependent transmission effects. An evaluation of the influence of these errors on the amplitude of the transmitted wave field will be presented. Also a discussion will follow on the question whether to decompose the elastic data before or after downward extrapolation .
