IS-4 SPATIALLY FIXED PATTERNS FOR RESOLVING LARGE MAGNITUDE SHORT WAVELENGTH STATICS AND MORE Abstract 1 In Saudi Arabia the complex three-dimensional near-surface overburden can introduce large magnitude short-wavelength time delays greater than half a period and wavelengths greater than half an effective spread length. Since automatic residual statics algorithms fail to resolve these statics additional geologic information is needed during the interpretation phase to constrain the near-surface model. These errors are overcome by combining this interpretation phase with a new partial-offset stack domain within a standalone PC-based interpretation system. This interpretation system uses multiple forward and reverse partial-offset stack displays
