Bazhenov fm. is one of the most important issues in the development of a new resource base to "Gazpromneft". Since recently several projects related to the oil and gas of Bazhenov fm. potential on the different scale (regional, zonal and local levels) are under development in the Company. In the framework of the regional assessment project of the Bazhenov fm. sediments (PBE) the area ranking according to the unconventional petroleum potential was carried out in 2012. The prolongation of the project in 2015 resulted in the formation of 3D petroleum system model which is unique in terms of cover area, model size and amount of input data. The model allowed for the evaluation and area ranking to be performed in the quantified manner. A detail prognosis of petroleum physicochemical properties for Bazhenov fm. was made combining petroleum system modeling methods and geochemical and physical data. Despite of long exploration history, huge petroleum potential of Bazhenov fm. and direct oil and gas manifestations a detailed assessment of the prospects was not conducted so far. A complete set of data was integrated into the model including experimental data. Primary and secondary cracking and HC migration modeling was modelled. Based on the result a number of maps was build describing petroleum potential and petroleum reserves. Gas and oil physicochemical properties depend on the OM maturity level. Using the density of oil and HC gas and gas saturation prognosis throughout the model Bazhen fm was evaluated. One of the main results of the work was the proposal of additional search parameter for assessing the prospects of the Bazhenov fm.
