This research demonstrates applications of statistical log analysis for the computation of multimineral composition and the formation evaluation of the Bazhenov unconventional play in Western Siberia. Effective and secondary porosities, as well as net thicknesses, are then evaluated according to the well-log interpretation workflow developed by Wendelstein et al. (2001). In particular, an analysis of elastic and mechanical properties of the Bazhenov formation in several wells has been performed and the identification of secondary porosity (fractured/ vuggy zones) based on crossed-dipole anisotropy analysis as well as determination of the most brittle rocks in the formation are discussed. Case studies for several fields, located in the Krasnoleninsky Arch and the Surgut Arch of Western Siberia, are shown. Finally, the advantages, limitations and drawbacks of the proposed approach are discussed.
