As a result timely, accurate, and geologically reasonable models can be produced. First, offset-dependent picking can be used to track events in gathers better than curvature-based picking, particularly in areas of complex geology and anisotropy. This implementation can allow quicker and simpler gather flattening and reveals fine detail in models.
The application of image-guided interpolation as a preconditioning step within the inversion process leads to updates which automatically respect geological structures observed in stacked images. When implemented within a current tomography flow, these refinements make generation of high-resolution velocity models reasonable without trade-offs in computation time or accuracy.
