Abstract
Summary
The near-surface can leave a strong imprint on seismic data. In order to be able to image deeper targets, we propose a full wave-field inversion approach to be followed by redatuming to the specific target level. The inversion scheme presented in this paper estimates iteratively the elastic properties of the model by trying to predict, at each iteration, one order of scattering of the data. We demonstrate the effectiveness of this idea on near-surface synthetic examples.
