Abstract: A method and apparatus for use in seismic prospecting are disclosed. The method comprises partitioning a plurality of converted split shear-wave data resulting from a common event and recorded at a plurality of azimuths and a plurality of offsets as a function of the azimuths and offsets; separating fast and slow split shear-wave wavefields in the partitioned data; deriving at least one attribute of at least one of the separated fast and slow shear-wave wavefields; and analyzing the derived attribute. The apparatus comprises, in one aspect, a program storage medium encoded with instruction that perform the method when executed by a computing device or a computer programmed to perform the device.
