Distinguishing Oil Generation Zones by IR Spectra of Chloroform Bitumens within Mezozoic and Cenozoic Deposits of the Azov–Kuban Oil-and-Gas Basin

Resumo

The use of IR spectrometry for examining the structural and group composition of chloroform bituminous components of dispersed organic matter in Mesozoic and Cenozoic deposits of the Azov–Kuban oil-and-gas basin resulted in obtaining significant information on the conditions of sedimentation and diagenesis of the deposits that enclose organic matter, as well as on its degree of katagenetic transformation. The IR spectra, which conformed to 15 genetic types of chloroform bitumen, allow one to distinguish the zones that contain no oil-and-gas source rocks, along with those with generation of hydrocarbons and those with completed processes.
