Concluding Remarks

The Husky data migration test results indicate that the TopoWEM approach is a viable migration from topography technique. This approach produced images of near-surface structure superior to Kirchhoff migration from a flat datum. However, future tests will create a better benchmark by comparing these results to Kirchhoff migration from topography. Kirchhoff migration from a flat datum results were similar at mid-to-basement depths indicating that the major imaging advantage probably is localized to the near-surface. Subsurface gathers for images indicate, however, that further work is needed to improve the velocity model, which may lead to a more definitive statement about the relative merits of the TopoWEM approach.
