Summary
We show the power of elastic full waveform inversion (EFWI) beyond deriving a velocity model for depth imaging. Instead, multiparameter elastic FWI (MPEFWI) inverts simultaneously a velocity model and a reflectivity of the subsurface. Application to a narrow azimuth data from offshore Brazil demonstrates that the inverted velocity model produces better depth image and the high resolution reflectivity can be used for quantitative interpretation in reservoir characterization.
