Abstract

The article is based on the example of the northern part of the Bashkir arch to make a zonal prediction of oil and gas potential based on the characteristics of dispersed organic matter (DOM). For this purpose, at the first stage of the study, the DOM was classified into types: syngenetic and epigenetic using various statistical methods. All this made it possible to construct individual and complex probability models for predicting epigenetic (the most migratory) dispersed organic matter. It was found that high values of complex probability correlate with discovered hydrocarbon deposits. This confirms the migration ability of bitumoids with the subsequent formation of commercial hydrocarbon deposits. Probabilistic DOM indicators that determine the complex probability of epigenetic DOM reliably control the oil and gas potential of sediments. The values of bitumen coefficient and insoluble residue have the maximum influence on the value of complex probability and on the differentiation of DOM. The insoluble residue has a high holding capacity and almost completely controls the process of differentiation of the organic matter up to the value of the complex probability equal to 0.55-0.6, then, as the complex probability increases, the influence of the insoluble residue weakens. The bitumen coefficient, in this case, affects the DOM differentiation in the whole range of complex probability change.
