Patent ID: 8164979

Claim:
A method of processing full elastic waveform data from seismic data obtained using a vertical-force source, comprising: retrieving seismic data from a storage device, the seismic data comprising P, direct SH and direct SV mode data, the direct SH and direct SV mode data representing seismic waves which were provided as SH and SV waves directly at a point of application of a vertical force source and sensed as reflections at multi-component geophones placed along the surface of the earth; and processing the seismic data using a processing circuit to generate full elastic waveform data, wherein the processing comprises: providing polarity correction to the direct SH and direct SV mode data to achieve horizontal shear wave mode and vertical shear wave mode data; segregating direct SH and direct SV modes from the seismic data; separately processing each of the direct SH and SV modes using at least one of a velocity analysis, a static correction, a noise rejection filter, a stacking process and a migration step; and generating direct SH and direct SV images based on the processing.
