effects <strong>of</strong> geology such as the impact <strong>of</strong> the inclination <strong>of</strong> strata on the velocity model is<br />
one area <strong>of</strong> future work. An explanation for the success <strong>of</strong> <strong>using</strong> a well-based velocity<br />
model for the PSDM is that sonic log velocities in dipping strata sample the horizontal<br />
velocity.<br />
My study has provided a benchmark for s<strong>eismic</strong> data, especially land data acquired over<br />
piercement salt domes and provides an opportunity to use data from this study to further<br />
the understanding <strong>of</strong> the geology <strong>of</strong> Vinton Dome and the surrounding areas. Details<br />
regarding structure and salt tectonics integrated along with the stratigraphy will yield<br />
greater precision. Building on the initial improvements in the geologic model <strong>of</strong> Vinton<br />
Dome will lead to a fuller understanding <strong>of</strong> geology.<br />
7.4 Conclusions and Discussion<br />
PSDM are not common to 3-D land surface s<strong>eismic</strong> data, there are several reasons for this<br />
some I have mentioned. A motivation for this study was to apply the current state-<strong>of</strong>-the<br />
art technology to data over a mature oil field. The goal <strong>of</strong> this study was to improve the<br />
spatial fidelity <strong>of</strong> s<strong>eismic</strong> imaging through a deterministic evaluation <strong>of</strong> surface s<strong>eismic</strong><br />
data with velocity modeling and attribute analysis. To achieve the goal and fulfill the<br />
motivations behind the study current methods had to be either modified or replaced.<br />
Identification <strong>of</strong> areas needing improvement required an assessment <strong>of</strong> current methods<br />
and testing. Testing allowed for data to be pre-migration processed in a manner that<br />
