Abstract

Summary

We discuss a TTI velocity model building approach that utilizes the well mis-tie information as inversion constraints. Since the well mis-tie information is available only at sparse locations, we introduce a bridging function to extend laterally the mis-ties information to its surroundings according to the local geologic structures. The resulting inversion scheme has the advantage of mitigating the illconditioning of the inversion operator and hence improves the robustness of the solution. We elaborate in detail this approach in this abstract and demonstrate with a real data example that the proposed method has both improved the positioning of depth migrated image and simultaneously enhanced the flatness of common image gathers.
