Preconditioning for Optimal 3D Stratigraphical and Structural Inversion

1 B-28 PRECONDITIONING FOR OPTIMAL 3D STRATIGRAPHICAL AND STRUCTURAL INVERSION Tectonic forces bend and tilt the earth’s crust and thereby create many of the structures under which we find hydrocarbons. However the bending and tilting also present a challenge to attribute computation and automated interpretation of the seismic data. Nevertheless local dip information is a crucial element in seismic stratigraphic internal reflection configuration [1]. Hence a robust seismic attribute should be able to handle dipping layers in a consistent way. For example the traditional approach of extracting attributes along vertical traces irrespective of any dipping nature of the data clearly
