An amplitude-based multiazimuthal approach to mapping fractures using P-wave 3D seismic data

摘要: We have tested an amplitude-based multiazimuthal approach for mapping fractures which requires only a simple azimuth-offset sorting process. By displaying the amplitudes of all traces collected within superbin, method predicts by P-wave amplitude variations, in lineation map indicates presence and orientation superbin. Test results using physical model field data sets suggest that could help to determine multiple fracture single layer, may be expressed through subtle variations seismic reflections. Our experiments with containing manmade vertical transmission effects one dominant factors control azimuthal versus offset (AVO) behavior.The technique described this paper can operate on any 3D wide azimuth distributions.
