VERFAHREN ZUR KOMPENSATION VON DREIDIMENSIONALEN NEIGUNGSDATEN ZUM EINFLUSS DER INHOMOGENEN ERDE

摘要

A three dimensional residual modeling operator is applied to seismic times that have been preprocessed by application of NMO and velocity independent DMO. The residual operator compensates for vertical velocity variation and anisotropy and its use precludes the need for ray tracing.
