Patent ID: 8139440

Claim:
A method for spectrally conditioning surface seismic data, comprising: correcting surface seismic data for distortions due to anomalous spectral amplitudes, thereby generating a first set of corrected data; correcting the first set of corrected data for deterministic distortions, thereby generating a second set of corrected data; correcting the second set of corrected data for spectral distortions due to the seismic waves traveling through the near-surface, thereby generating a third set of corrected data: and correcting, using a microprocessor, the third set of corrected data for spectral distortions due to the seismic waves traveling through deeper strata by: performing a surface consistent absorption analysis using the third set of corrected data to generate a set of absorption parameters having global, offset and common mid-point parameters; and performing a surface consistent absorption compensation filtering using the third set of corrected data and the global, offset arid common mid-point parameters.
