In land seismic data processing, refracted wave travel-times are widely exploited for solving near-surface characterization challenges. Mainstream approach includes ray-based refraction tomography for velocity model building and data-driven static estimation. Those methodologies, solely relying on refraction picktimes, suffer from picking errors and from the intrinsic non-uniqueness of the refraction inverse problem. In this paper, two innovative solutions for overcoming the limitation of refraction-based techniques are presented. The first is the integration of independent geophysical information into the velocity model building process, achieved through the Simultaneous Joint Inversion (SJI) of refracted and surface waves. The second is a novel processing workflow that exploits refracted travel-times estimated by SJI to improve the original first break picks and, as consequence, the statics.

Both the solutions have been applied to a challenging 3D dataset, bringing sensible uplift from industry standard results.
