Improvement of the MVD method (Migration Velocity Determination)
Abstract
The application of the notion of migration to seismic traces for the purpose of seismic velocity determination is examined. Accurate knowledge of seismic velocities is a prerequisite for good results in geophysical data processing as well as an important aid in the interpretation of a seismic section. The migration velocity determination method is applied to two and three-dimensional problems and a dip selective version is developed for complex cases with interfering events. The development is carried on with a computer method (ANAKON) which allows an improved velocity analysis for selected interfaces. First results of this last method are shown.
