Polarization Analysis on Seismic Data after Multicomponent Wavefield Filtering

P12 POLARIZATION ANALYSIS ON SEISMIC DATA AFTER MULTICOMPONENT WAVEFIELD FILTERING Abstract 1 C. PAULUS J. I. MARS Laboratoire des Images et des Signaux Institut National Polytechnique de Grenoble BP 46 Saint Martin d’Hères France Seismic exploration and reservoir study require information conveyed by reflecting waves. In case of multicomponent dataset (3C 4C…) classical methods such as FK filtering τ-p filtering SVD give relatively poor results since they do not take into account all the information conveyed by multicomponent sensors or they require pre-processing. Recently we’ve developed an extension of the Spectral Matrix Filtering method (SMF) called MultiComponent WideBand Spectral Matrix
