摘要

Method for migrating data in depth su00ecsmicos migration time using pre stack depth migration, demigrau00e7u00e3o, and post - stacking. The present invention relates to a method for depth migration of seismic data. The method includes migrate in time for pre stack seismic data to form an image, stacked, migrada in time.The image migrada stacked in time is demigrada, and a depth migration after stack is then performed on the image demigrada. In some arrangements, the migration time of pre - stack and the demigrau00e7u00e3o take into account the curvature radius and the vertical transversely isotropic media.
