A Data-Mapping Approach to Redatuming

By incorporating a redatuming step in the seismic processing stream, the quality of the seismic image will be improved. An important issue with respect to redatuming is the application to 3D data acquired by conventionally used acquisition designs. Because of the sparseness of these data, it is impossible to apply the conventional wave-equation datuming method. <br>In this paper, we present a new redatuming methodology, which follows the concept of Kirchhoff data mapping. The proposed approach is tested on 2D and 3D synthetic data sets and shows satisfying results.<br>
