Migration Workflow

Prestack Depth Migration Workflow is based on the assumption that the correct velocity model will produce flat migrated gathers. If migrated gathers are not flat it indicates the presence of a velocity error. These errors are used as input to our tomographic algorithm to generated an updated velocity model. This new updated velocity model is used to re-migrate the data and eliminate the depth errors.

BE® Imaging is a preprocessing step that enhances the spectral content of the data making it broadband and hence higher resolution.
