ORGANIC-GEOCHEMICAL STUDY OF OIL SHALES IN PRE-CASPIAN-GUBA REGION (AZERBAIJAN)

Abstract

Based on the results of the studies, an insignificant difference in the geochemical characteristics of oil shales were established within the study area. The amount of OM in the samples taken from the outcrops and pits varies from 13,3 to 32,1 %. Based on the data of gravimetric studies and two-stage pyrolysis, the maturity of OM was assessed and the aliphatic type of OM was established. The Tmax obtained during the cracking process indicates the immaturity of the OM of shale rocks for the generation of hydrocarbons.
