Overview

The structure of this paper will be as follows. First, we give a brief introduction to the present research. In particular, motivations and potential applications of the Kirchhoff migration/inversion method to seismic exploration and reservoir characterization are suggested. Second, we give a very brief outline of the mathematical and physical theoretical concepts to give an intuitive foundation to the overall approach. Next, we demonstrate the technique with a synthetic data application. Several migration and inversion issues are examined using primary synthetic seismograms generated from a reasonable estimate of the true earth model at an actual field survey site. The synthetic results serve as a control in terms of what we should and should not expect to recover in the elastic parameter depth images obtained from the field data. Finally, a presentation and interpretation of the field data results will be given at a later date pending proprietary release. Further details are in manuscript preparation for publication and will appear in subsequent SEP reports.
