Обработка широкоазимутальных данных с использованием интерполяции COMFI 5D

Seismic amplitude and velocity variation with azimuth is typical for azimuthally anisotropic medium. The estimation of seismic anisotropy by qualitative measures, such as fracture orientation, and quantitative evaluations tied with well data, allow to get more information for further fracture reservoirs exploration. Seismic data processing of wide-azimuth 3D data with respect to anisotropy estimation includes special technical procedures. In this paper some techniques of 3D azimuthal processing in West Siberia for HTI-anisotropy estimation are discussed. Fracture-induced anisotropy assumed to present in the data because of amplitude and velocity distribution specification. Data were splitted into 6 azimuth groups; PSDM with further CIP-RMO velocity corrections was run for every group. For more stable azimuthal characterization input wide-azimuth data need to possess sufficient fold. An interpolation technique with respect to the azimuth of the seismic traces, such as COMFI 5D, enhances quality of regularized data and reduces regularization artifacts. Final seismic data are suitable for further AVO-AVA azimuthal inversion. In this paper discusses implementation of 5D regularization technique for azimuthal data processing based on real project
