Abstract:The offset vector tile (OVT) is an entirely new prestack data arrangement means.The azimuthal anisotropy of seismic data is more evident when seismic data is sorted into the OVT domain.With data processing tools provided by GeoEast System,wide-azimuth seismic data in Zigong,Sichuan are processed into the OVT domain for the shale gas exploration.The anisotropy of the whole survey is obtained,which proves correctness and effectiveness of the OVT processing tools in the shale gas exploration.
