The site is a tunnel crossing a thick Toarcian shale formation. The seismic tomography experiments were performed between three wells oriented along different radial directions from the axis of the tunnel. The good angular coverage of the seismic rays allowed to invert for the P-anisotropy parameters of the shale considered as transversely isotropic. The tunnel is situated in the
