Abstract. The prediction process of reservoir properties is one of the significant targets during an explo-ration stage on the Srednebotuobinskoye field. At the moment, there are a lot of well data, including log and core data. The authors get conclusions regarding a formation and structure of the osinskiy horizon within the Srednebotuobinskoye field. The petrophysical model and the log data interpretation in osinskiy horizon based on actual information were completed. The petrophysical basis of seismic inversion was completed. It is proposed that the employment of the optimal approach to seismic inversion process can help to get more precise prediction reservoir maps than earlier and to minimize exploitation drilling risks. .
Keywords: carbonate deposits, Osinsky horizon, ring anomaly, zones with improved porosity and permeability properties (PPP), hydrocarbons (HC).
