The migration time domain is quite employed by the oil industry for its low computational requirements, however in areas where the velocity field has great lateral variation as result of the environment is complex subsurface structures, such as faults, salt domes, etc.., this technique becomes inefficient in the characterization of geological features. Although the computational cost is high, migration in the field of depth, proves more effective than time migration to deal with these structures. However for a section in depth there is a need for a velocity model in depth with some degree of precision. In this paper, two methodologies for time to depth conversion for obtaining the velocity model in depth to two real 2-D marine lines Jequiti...
