Abstract

Summary

We propose a simultaneous Joint Migration and Inversion (SJMI) method for time-lapse migration/ inversion, which combines a joint time-lapse data processing strategy with the Joint Migration and Inversion (JMI) method, and also extend it to include an L1-norm sparsity constraint on the reflectivity model-difference in a suitable transform domain and a total-variation (TV) edge-preserving constraint on the velocity model-difference. We tested the proposed method with two synthetic examples, from which it is shown that our method is effective, even when the datasets contain strong noise, are generated by different acquisitions, and also contain a strongly scattering overburden.
