P277 Full Waveform Inversion of Shot Gathers in Terms of Poro–Elastic Parameters L. de Barros (Université Joseph Fourier) & M. Dietrich* (Institut Français du Pétrole) SUMMARY We have developed a full waveform iterative inversion procedure for determining the porosity permeability interstitial fluid properties and mechanical parameters of stratified porous media. The inverse problem is solved by using a generalized least-squares formalism. The proposed method achieves computational efficiency through semi-analytical semi-numerical solutions for calculating the reference and perturbation wave fields from Biot’s theory. When this algorithm is applied to noise-free synthetic data it is found that the inversion of a single
