Imaging with multiples using linearized full-wave inversion

Conclusion

We demonstrated a method for imaging both primaries and multiples using linearized full-wave inversion (LFWI). LFWI not only increases the sub-surface illumination by using the multiple energy as signal, but also addresses the issue of crosstalk in the image. We demonstrate the concept and methodology with a 2D layered model and the Sigsbee2B model.
