Bornard (CGGVeritas) SUMMARY We present a new stochastic algorithm for the inversion of multi-angle seismic reflection data and well logs. The probability distribution of P- and S-impedances in the subsurface is characterised by a set of representative and mutually-independent samples or realisations. Each of these realisations not only fits the observed data to within defined tolerances but also satisfies lateral and vertical spatial correlations from geostatistics. Thanks to a judicious choice of
