Deep petroleum occurrences in the lower Kura depression, south Caspian basin, Azerbaijan: an organic geochemical and basin modeling study

Abstract

High sedimentation rates (as much as 2500 m/Ma) during Pliocene-Pleistocene, with a resultant undercompacted section as thick as 10,000 m, and lower than normal geothermal gradients are the main characteristics which have created all the means for generation and preservation of oil at deep layers in the Lower Kura Depression.
