Solutions to regional problems of forecasting oil bearing according to geological and geochemical analysis of dispersed organic matter of Domanic type rocks

Authors: V.I. Galkin, I.A. Kozlova, M.A. Nosov, S.N. Krivoshchekov (Perm National Research Polytechnic University, RF, Perm)

Key words: geochemical parameters, disseminated organic matter, bitumens, probabilistic model, the generation, accumulation, Domanic stratum , the forecast oil and gas potential.

The paper based on the study of geochemical parameters of dispersed organic matter of Domaniс type rocks. Processes of hydrocarbons accumulation are modelled and the complex probabilistic criterion is obtained for oil potential in the Paleozoic sediments. For various tectonic elements in Perm region authors estimated the ratio of hydrocarbons generation and accumulation for each horizon of studied strata. A regional scheme of oil and gas prospects is constructed.
