C023 3D VELOCITY MODEL DETERMINATION WITH KINEMATIC WAVEFIELD ATTRIBUTES E. DUVENECK AND T. KLÜVER Geophysical Institute University of Karlsruhe Hertzstr. 16 76187 Karlsruhe Germany Summary A tomographic inversion method is presented which uses traveltime information in the form of kinematic wavefield attributes (first and second spatial traveltime derivatives) to determine smooth laterally inhomogeneous 3D subsurface velocity models for depth imaging. The kinematic wavefield attributes can be extracted from the seismic prestack data by means of the common-reflection-surface (CRS) stack. The required input for the tomography can be picked in the resulting stacked zero-offset volume. Only very few picks are required
