Full Waveform Inversion of VSP Data for Prediction of Impedances bellow Borehole Bottom

This work is devoted to the studying of possibility of implementation of full waveform inversion for arrangement the elastic impedances bellow the borehole bottom. The VSP surveying system with one offset source is used. We deal with 2D isotropic elastic media. In this paper we present the result of singular value decomposition (SVD) analysis. Also some numerical results of inversion are shown.
