ABSTRACT OF THE DISCLOSURE A method for improving the seismic resolution of geologic structures is disclosed. Refracted wave arrivals are gathered into common midpoint trace gathers. Data representations originating inside a critical offset distance are muted, and the remaining data is tau-P summed and projected into zero source-to-receiver offset. Constant velocity stacks can then be displayed. A plurality of common midpoint trace gathers can be used to generate multiple panels of tau-P sums. Portions of several of these panels can be combined to provide a complete image of the subsurface reactors. A near-surface velocity model can then be designed, to provide a solution to near-surface statics in seismic traces.
