Technical Abstract

Joint Inversion of Refracted P-waves, Surface Waves and Reflectivity

Back to Technical Content
A joint inversion of P-wave first arrivals, surface wave dispersion curves, and horizon picking of reflectivity image is proposed in order to produce a high resolution Vp (and Vs) model of the near-surface. These three datasets are merged together in a stochastic optimization process through a normalization taking into account of these different domains in the cost function. Resulting model is geologically consistent and reconcile wave velocities and the shallow reflectivity.
