Abstract: Use of Gravity Data to Enhance Seismic Depth Migration

Mark E. Weber, Brian S. Anderson, Barry C. Wiggins


Seismic depth migration continues to be an important, but expensive, tool for reducing exploration risks. Newly acquired high-resolution gravity data provide a low-cost method to enhance the seismic depth migration process by providing an independently measured constraint to the seismic velocity model. State-of-the-art commercial software tools enable rapid integration of the gravity and seismic data. In many geologic settings, integrated density/velocity modeling yields a more accurate velocity model than can be derived from the seismic data alone. A case study is presented to illustrate both steps employed in the data integration process and the resulting improvement in depth-migrated seismic data.
