Geostatistical seismic inversion methods are routinely used in reservoir characterization studies. This is due to their potential in inferring the spatial evaluation of the petro-elastic properties of interest (e.g. density, elastic and acoustic impedances) along with the associated spatial uncertainty. In this study, an extension of a previously introduced geostatistical seismic inversion method was developed in which local multi-distribution functions and spatial continuity models under non-stationary conditions were taken into account. The proposed method was applied to a highly non-stationary synthetic seismic dataset with different levels of noise. The results clearly showed the advantages of the proposed method against the conventional geostatistical seismic inversion procedure. It is important to highlight the impact of this technique in terms of a higher correlation coefficient between real and inverted reflection seismic data and the more realistic approximation of real subsurface geology comparing with the traditional technique. © 2016 SEG.
