Seismic Characterization Of Near-Surface Drainage Pattern: Bull, Oklahoma

We demonstrate the use of velocity model from inversion of first arrivals in depth imaging. We demonstrate the imaging application for an ultra shallow (<15m) geological target which is a set of paleo-channels in the Bull Creek, Bever County, Oklahoma. To demonstrate the concept two coincident profiles were acquired — one targeted towards inversion and the other towards migration. Besides migrating data with the inversion model, we also migrate the data with velocity model developed though conventional processing. We compare the results to realize that significant improvements can be made in imaging of the shallow subsurface by using velocity models created by traveltime inversion.
