At any stage of field development, the process of developing and history-matching geologic and hydrodynamic models has many uncertainties. To improve reliability of geologic and hydrodynamic models all the available information shall be used. For undeveloped fields, these are the results of hydrodynamic well tests at the stage of early production, and for fields with a high degree of exploration all the available information shall be objectively integrated. This paper considers various approaches to improvement of geological and hydrodynamic models’ reliability. The authors propose a method of hydrodynamic model history-matching to indicator diagrams results. To refine permeability cube at underexplored fields, it is proposed to history-match the geologic and hydrodynamic model to the results of hydrodynamic tests carried out at exploration stage. For fields with a high degree of exploration, it is proposed to integrate different studies. Linear discriminant analysis was used for this purpose. As a result, this allowed to significantly reduce the model adaptation time and increase its predictive reliability.
