Methods for Assessing the Quality of Seismogeological Models

Abstract

The report describes a systematic approach to the construction of stochastic geological and hydrodynamic models based on the results of seismic inversion. Using the results of stochastic inversion can improve the quality of the geological model , giving an idea of ​​areal and volumetric distribution of permeability and porosity of the formation. But especially important to determine the criteria for the presence of the reliability of the geological model. Such criteria , in our opinion may make the data field development , that is, to assess the validity seismogeological model should build a hydrodynamic model and to evaluate the convergence of the calculated and actual performance. Well the advantages of such an approach to modeling manifest in the performance of integrated projects , where the inversion results fall into the geological model, which becomes the basis of the filter model. Our company has accumulated experience in building projects stochastic geological and hydrodynamic models based on the results of seismic inversion.
