Abstract
The report addresses the urgent problem of the use of seismic data for geological modeling. Very often, when constructing a geological model, all the contradictory elements of the seismogeological model are discarded due to their incomprehensibility without any analysis, which contradicts the main concept of seismic application - the interpolation of the properties of the medium in the inter-well space. A technique is proposed that can overcome the existing gap between the seismogeological model and the geological model. The main stages are 1) the construction of an a priori geological model based on the results of deterministic inversion, 2) the use of the obtained a priori model in calculating the multiple realizations of stochastic inversion with 3) the subsequent ranking according to a system of specially developed criteria. The application of this technology is illustrated by the example of one of the oil fields of Eastern Siberia.
