We propose a laterally constrained surface wave inversion to obtain a reliable near-surface shear-wave velocity field from Rayleigh wave measurements. This workflow is targeted at dense 3D broadband wide-azimuth land surveys, aiming to obtain reliable and realistic lateral shear-wave velocity variations pertinent with regard to surface or sub-surface information. We applied our methodology to a dataset acquired by Petroleum Development of Oman in the Sultanate of Oman. The S-wave velocity model obtained can be easily correlated to surface data, satellite map and time-reflectivity volume, hence demonstrating the potential of our method to build reliable and geologically consistent near-surface velocity models.
