Abstract
A model of the Bazhenov formation hydrocarbon system was calculated of an area of about 13,000 km2 including the territory of Priobskoye, Prirazlomnoye and a number of other oil fields discovered in the Frolovskaya megadepression and the Salym megaval in the West Siberian basin. Temperature history was simulated in two programs: TemisFlow and GST using heat flow maps and maps of modern temperatures of the Bazhenov formation. The amount of hydrocarbons generated by the Bazhenov formation was estimated using the organic matter transformation ratio map and the residual generation potential map. Hydrocarbon capacity of the Bazhenov formation was calculated in two ways: by using S1 pyrolytic parameter and based on the results of basin modeling. The initial total geological oil resources of the Bazhenov formation were estimated and compared between each other using three approaches: basin modeling, quantitative geological regularities and volumetric methods. All three estimates fall within the range of 74–90 mln t.
