Full Waveform Inversion of elastic dataset is challenging due to the complexity introduced by free-surface effects or P-S waves conversions among others. In this context, large offset are prefered for inversion because they favour transmission modes which are more linearly related to P-wave velocity. In contrast, the problem addressed here is whether short offset inversion should be suitable for seismic imaging. To answer this question, we choose to invert an elastic dataset obtained from the SEG/Overthrust SEG/EAGE model, with simultaneous inversion of Lamé parameters. We will show that by using short offset and with only minimal pre-processing of the data (e.g. low-pass filter), we are able to construct reliable gradients. This, in turns, leads to accurate inversion of both shear and compression velocity models.
