Seismic analysis using post-imaging seismic anisotropy corrections

Abstract From the Canadian patent

System and method for performing anisotropy corrections of post-imaging seismic data for a subsurface formation. The method may receive seismic data preferably pre-stack seismic data comprising a plurality of traces e.g. collected from a plurality of source and receiver locations. The seismic data may be imaged/migrated to produce imaged seismic data which is organized into , an arrangement that preserves aspects of the relative seismic propagation angle in the subsurface. One or more anisotropic parameters and corresponding corrections may be determined by analyzing the organized imaged seismic data. The determined parameters or corrections may be used to correct at least a subset of …
