[54] SURFACE CONSISTENT STATICS SOLUTION AND AMPLIFICATION CORRECTION
[57] Abstract: SURFACE CONSISTENT STATICS SOLUTION AND AMPLIFICATION CORRECTION ABSTRACTMethods for correcting seismic signals by determining a signature of an outcropping geobody (e.g., a sand dune) from unprocessed seismic data, attenuating the seismic data using a variable gap deconvolution, and performing a surface consistent deconvolution and amplitude correction on the seismic data. A signature associated with the outcropping geobody and corresponding to the geometry of the geobody may be identified from the unprocessed seismic data. The signature may be used in subsequent processing, such for the determination of a variable gap length for a variable gap deconvolution applied to the seismic data. Computer-readable media and systems for correcting seismic signals are also provided.
