Abstract
P025 Summary FRESNEL-VOLUME MIGRATION OF ELASTIC SEISMIC DATA WITH LOW SPATIAL COVERAGE S. LÜTH 1 A. GOERTZ 2 S. BUSKE 1 and R. GIESE 3 1 Institut für Geologische Wissenschaften Fachrichtung Geophysik Freie Universität Berlin Malteserstraße 74-100 12249 Berlin Germany 2 Paulsson Brea USA 3 GeoForschungsZentrum Potsdam Germany A method for imaging multi-component seismic data using vector Kirchhoff migration with a restriction to the Fresnel volume of the reflection wave path is proposed. This method is particularly applicable for seismic data with restricted aperture as e.g. along tunnels or VSP. We use the polarization direction of multi-component data in order
