Abstract

Information on the structural-group composition of organic matter is important for the evaluation of kerogen maturity and oil generation potential of unconventional reservoir rocks. In the work kerogen samples (type II) of the Bazhenov formation of the West Siberian oil and gas basin have been studied. On the example of unconverted kerogen and the middle of oil window kerogen samples, the possibilities of structural-group analysis of the high-carbon organic matter of the Bazhenov formation by FTIR spectroscopy by recording transmission and attenuated total reflectance spectra have been shown. It has also been shown, that the IRcoefficients characterizing aromaticity, branching and aliphaticity of organic matter allow to evaluate the maturity degree using on the example of type II kerogen, and the obtained data are in good agreement with the results of Rock-Eval pyrolysis and elemental analysis.
