We have introduced a technique that addressees an important problem in seismic processing: the elimination of multiples in the image space with a not-yet-perfect initial velocity model. The combination of SRM and MAIS yields a procedure that can safely clean multiples from the data before performing any migration-velocity-analysis technique.
This technique yielded satisfactory results when applied to a 2-D line of the Mahogany field. The multiples were separated and eliminated from the primaries in the image domain, while our velocity analysis model was still incorrect.
Because both SRM and MAIS work separately on 3-D data, this technique might be useful in 3-D for eliminating multiples in the image space, in parallel with estimating a suitable migration velocity model.
