Imaging with multiples using linearized full-wave inversion
Mandy Wong, Biondo Biondi, and Shuki Ronen
We presents a technique for imaging both primaries and multiples using linearized inversion.
When used with a suitable migration velocity model, linearized full-wave inversion (LFWI) makes use of the multiple energy as signal while removing the crosstalk in the image.
By using the two-way propagator in both modeling and migration, we can image a class of multiply scattered events.
Such events can scatter off sharp-interfaces in the migration velocity many times but only interact with the (reflectivity) model once.
We demonstrate the concept and methodology in 2D with a synthetic Sigsbee2B model.
