f Depth Imaging Using Ftg Gravity And Pre-Stack Seismic Depth Migration: Case Studies From The Deepwater Gulf Of Mexico

In the deepwater GOM, allochthonous salt bodies<br>obscure seismic imaging of deeper geologic features.<br>Gravity and full tensor gradient (FTG) data, which<br>respond to the significant density contrasts associated<br>with the salt bodies, are highly useful when<br>integrated into the pre-stack depth migration<br>(PrSDM) imaging workflow for sub-salt targets. In<br>this paper, we will discuss:<br>• What is Full Tensor Gradient (FTG) data?<br>• Why is it important?<br>• How do we use it for depth imaging?<br>• What improvements have been realized when we<br>incorporate FTG data into depth imaging in the<br>Deepwater GOM, and what factors enabled high quality results?
