EXECUTIVE SUMMARY
The main objectives of this study have been to investigate the vertical extent of oil window to aid future exploration of deeper horizons in the Lower Kura Depression. Additionally, determinations of possible source rocks that contributed to oil accumulations, timing of oil generation from these source rocks and characterization of petroleum occurrences in the study area have been investigated.
In this study, we approach the problem by utilizing detailed organic geochemistry of oils and available source rocks (from boreholes and rocks ejected from mud volcanoes) and computer-aided modeling which simulates physico-chemical and geological processes.
Detailed organic geochemical data on 26 crude oil samples from nine oil fields and some hydrocarbons extracted from the rocks of the Eocene-Pliocene sequence in the Lower Kura Depression of the South Caspian Basin are presented.
Oil accumulations seem to be associated with all of the potential reservoir rocks within the Miocene-Quaternary stratigraphic sequence which consists of alternating shale (siltstone) sand beds of a typical prograding delta. Paleogene and Cretaceous rocks, lying at depths greater than 6-6.5 km, have not been penetrated by drilling; however, they have been brought to the surface by mud volcano activities. This provides a unique opportunity to study the organic geochemical properties of these older units.
