摘要：The present invention relates to an improved method and system for computing residual statics on shear wave seismic data. The invention uses pilot traces, which are a function of CDP, offset, and azimuth, to resolve shear wave data in the presence of any anisotropy. Statics determinations are made that are not velocity error dependent; the need for CMP to CCP transformations is eliminated. The present invention also relates to a method and apparatus for removing regional anisotropy effects. The present invention, in one embodiment, determines statics for shear wave seismic data by binning seismic data in a bin defined by CDP information, azimuth information and offset information, where a set of binned traces is defined; generating a pilot trace from the set of binned traces; cross-correlating the pilot trace with the binned traces; determining shot statics dependent on the cross-correlation; and determining receiver statics dependent on the cross-correlation.
