This report continues our work on refraction seismic modeling in Rayfract\u00AE and explores new possibilities offered by the software to create reliable starting models for Wave Eikonal Traveltime (WET) inversion. For this purpose, we used two complex models based on traditional interpretations from Knappe tunnel survey i.e. P1-1 (120 m) and P1-6\/7 (240 m). The first model contains three vertical fracture zones below a thin overburden and the second involves a pair of fracture zones overlain by a thick overburden basin.
