Abstract
The methodology of complex lithofacial sedimentary rocks analysis with the subsequent multivariate geological and hydrodynamic reservoir model run is presented. The suggested approach gives opportunity to elaborate and significantly improve the oil production forecast and increase the investment attractiveness of the green assets development projects at the stage of detailed field exploration and appraisal. During the project realization, the sedimentological core description, the seismofacial analysis, the detailed well logs correlation tasks were carried out, three variants of the conceptual model corresponding to the quantiles P90, P50, P10 were substantiated.
Also the sensitivity analysis of initial geological oil reserves in place and the accumulated production volume to geological and hydrodynamic uncertainties variation was completed.
