Full-waveform inversion (FWI) has been used as a major tool for high resolution imaging since the first paper of Tarantola(1984). It uses all measured events such as diving waves, critical reflections and multiples to develop an earth model out of these data. In this paper, We use elastic FWI to simultaneously estimate P-wave and S-wave velocities from real field data. FWI consist basically of two major steps: Forward modeling and backward propagation of data residuals. Modelling of the seismic wave-field requires a solution of the partial differential equations. Velocity models obtained through FWI were promising as they shows the complexities of channels in the shallow part.
