Abstract
Various geobodies have specific shape on vertical and horizontal projections resulting in geometrically anisotropic features in seismic data. Such features can be enhanced by performing controlled directional transform of seismic attributes based on local linear Radon transform. The approach is to represent results of such transform as polar diagrams, which are then used for anisotropy magnitude estimation as well as number of its prevailing directions and their azimuths. These data are helpful in emphasizing anisotropic features and can even help to distinguish some of them (faults and river channels). Other possible applications of this method include azimuthal filtering and automatic tracking. The proposed approach aids geological interpretation in a variety of ways while being flexible to perform on different structural and dynamic attributes.
