[1] Composition of pyrolyzed hydrocarbon compounds from the organic matter of bazhenov formation / E. V. Kozlova, M. Y. Spasennykh, N. N. Bogdanovich et al. // EAGE/SPE Joint Workshop 2017. Shale Science: Prospecting & Development 10-11 April 2017, Moscow, Russia. — EAGE Publications, 2017. Pyrolysis of rocks is one of the most important among set of geochemical methods of organic matter investigation. It is instrument for determining the quantity, quality and maturity of organic matter of source rock, but also investigation tool to study of reservoir fluids and recovery of kinetic characteristics of kerogen destruction. The pyrolytic data play important role in basin modeling and they are required for the correct calculation of hydrocarbon reserves and resources. The content in the rocks of liquid and gaseous products of thermal evaporation, as well as the hydrocarbons formed in the cracking of kerogen (pyrolysis parameters S0, S1 and S2) and their relations, which depend not only on the composition deposits, but also on the degree of their maturity level is the basis for modelling of oil generation and oil recovery from complicated system of Bazhenov Formation. The paper presents the interpretation pyrolytic data algorithm of samples before and after extraction with organic solvents for Bazhenov Formation, allowing to estimate group and molecular composition of pyrolyzed hydrocarbons.
