Processing that moves recorded reflection energy to its inferred subsurface positions using a velocity model. It corrects apparent positions of dipping reflectors and collapses suitable diffraction events; insufficient spatial sampling and incorrect velocities impair the result.

Seismic migration is a geophysical imaging technique used in the interpretation and processing of seismic data, primarily in the context of exploration geophysics, such as oil and gas exploration. The primary goal of seismic migration is to accurately position and clarify the subsurface geological structures and reflectors identified through seismic surveys.
