Tomographic model uncertainties and their effect on imaged structures.

We demonstrate a recently developed method for computing tomography model uncertainties and mapping them into the migrated domain. The method generates after the final tomography a series of equi-probable velocity model perturbations within a standard deviation confidence level. This allows computing standard deviation-like attributes for velocity and anisotropy parameters and for key horizons. An application to West of Shetland dataset highlights the interest of the estimated uncertainties.
