Abstract
Abstract: Use of Gravity Data to Enhance
Seismic
Depth Migration
Abstract
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.
