Reflection full waveform inversion is a formulation of full waveform inversion designed to extract low wavenumber velocity information from the reflected wavefield. In this works we extend reflection full waveform inversion to an elastic framework. This allows the estimation of both P-wave and S-wave velocities using reflected waveforms. We apply the method to a 3D-3C field dataset. The results clearly show that the velocities estimated with the method improve the quality of the PS image. The method is also able to incorporate in the velocity model information about the location of channel deposits at a depth of about 1200 meters.
