In this paper we present the approach to prediction of reservoir properties distribution for carbonate reservoir of Timan-Pechora petroleum province based on petro-elastic modelling. The main idea of the approach is integration of multiscale reservoir surveys. Several rock types (lithotypes) were distinguished during lithologic analysis based on core description. Formation evaluation has been done by detailed lithological and petrophysical core-log interpretation. The effective petro-elastic model is identified for the considered reservoir. By the analysis of petro-elastic model parameters the criteria were established for prediction of reservoir properties by seismic data based on amplitude inversion.

Development and implementation of approaches for prediction of reservoir properties distribution based on petro-elastic modelling is of genuine concern.

In this paper we show application of petro-elastic modelling approach for one of the field of Central-Khoreyver Uplift. The considered approach can be applied for neighbor fields or for the analogous carbonate reservoirs.
