Seismic imaging problems impede exploration in many areas of the deepwater Gulf of Mexico. In an effort to address this problem, many companies rely on gravity and magnetic data to guide their seismic imaging and interpretation.

Commonly, the procedure begins with a forward model of sediment density and proceeds to a final model, which matches the observed gravity to some appropriate degree of accuracy. This final model can be used during the salt flood and sediment flood stages of seismic depth imaging and also later in the interpretive process. Gravity data have value because they provide an independent view of...
