Thoughts and Observation on Interpreting Depth-Imaged Data in the Jurassic Norphlet Play, Deepwater Eastern Gulf of Mexico
When working with depth-imaged data an interpreter must visualize how a depth migration velocity model affects focusing and positioning of reflections in final images and, consequently, interpretation of the geology contained in those images. The availability of several versions of depth imaging based on a single velocity model but with different migration algorithms requires an interpreter to decide which version provides the most accurate representation of the true geology. This is especially challenging in the Jurassic Norphlet play of the deepwater eastern Gulf of Mexico because of the depth of Norphlet targets, their proximity to salt, and their position immediately beneath high-velocity Smackover Limestone.
