In summary, migration is a digital operation in which the reflections on the seismic traces are moved to their correct locations in space. Migration requires the primary reflected events. What else is required? The answer is the seismic velocity function v(x,y,z). The velocity function is required to determine the raypaths of the admissible reflections. The velocity function gives the wave velocity at each point in the given volume of the earth that is under exploration.
