Adequate handling of the near surface is crucial for proper imaging of land data, especially for complex overburdens. Recently we introduced modal elastic inversion ( ): approximate FWI which inverts P-guided waves to near-surface P-velocity models. We will present two case studies of modal elastic inversion of P-guided waves to obtain near-surface velocity models. The results show that this inversion approach can give realistic results not only for modern high-end densely sampled surveys, but also for sparse legacy dynamite surveys.
