Gazpromneft NTC LLC specialists made regional works on the conceptual geological modeling of oil-producing and potentially productive BV reservoirs of the Ob River left bank on the Slavneft-Megionneftegas JSC activity area which includes 8 license blocks in order to clarify geologic structure and to audit the resource base. Conceptual model based on united cube of reprocessed seismic data within the area of more than 2700 km2. As a part of the work, the correlation of BV group reservoirs was rebuild at the area of 5000 km2 (about 1800 wells among 9 oilfields). The methodology of V.S. Muromtsev was used to subtract etalon electrometric facies models of the Left bank oilfields group and to obtain facies distribution maps and reservoir properties. The regularities of BV group deposits formations were revealed and potentially productive areas were recommended for further appraisal and preparation of a development strategy for current deposits. According to drilling of new wells a practical confirmation of conceptual model was obtained. This experience proliferates to other assets of Slavneft-Megionneftegas JSC.
