Estimation of hydrocarbon potential is an essential part of the field exploration. It usually involves traditional methods. Nevertheless, there are many alternative methods of quantitative estimation of potential reserves at the particular area nowadays and fractal analysis is one of them. This method of hydrocarbon potential prediction was applied for one of the field confined to Vyngapursky bank, Western Siberia. During fractal analysis volume of undiscovered oil estimated as 54 mln.tons of oil, where Neocomian complex includes 26.85 mln.tons and Jurassic – 19.75 mln.tons of potential oil resources. From the exploration maturity point of view, the Field S is highly studied, up for 90%, while for Cretaceous layers up for 95%, Jurassic layers up for 78%. Jurassic complex was estimated the most perspective over the Field S, since it has 28% of undiscovered hydrocarbons yet, So, this volumes occupies an area, concentrated at seismic anomaly area within the study area, and equals to 78 km2 . The amount of potential accumulations vary from 5 to 52.
