Abstract
Wave equation processing algorithms are available to image very complex structures. In most cases these processes are limited by our ability to estimate the correct velocity field. There are two types of migration Velocity Analysis (MVA) that use migration as a tooI to estimate velocity. The first type, velocity scanning MVA, prestack migates the data with a suite of velocities.
