Abstract: Use of Gravity Data to Enhance Seismic Depth Migration

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

Abstract

Seismic depth migration continues to be an important, but expensive, tool for reducing exploration risks. Newly acquired high-Previous HitresolutionNext Hit gravity data provide a low-cost method to enhance the seismic depth migration process by providing an independently measured constraint to the seismic Previous HitvelocityNext Hit model. State-of-the-art commercial software tools enable rapid integration of the gravity and seismic data. In many geologic settings, integrated density/Previous HitvelocityNext Hit modeling yields a more accurate Previous HitvelocityTop 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.
