ABOUT THE SOURCE ROCK OF THERAPEUTIC OIL OF THE NAFTALAN FIELD

Abstract

The Naftalan field is a unique natural object not only because of the widely known healing properties of the oils, but also the variety of the composition of the oils available here. Thus, different types of oil at this field are spatially distributed, namely, therapeutic oil is strictly limited to the Upper horizons of the Maikop formation in the depth interval of 500-600 m, while the Lower horizons of this formation are saturated with fuel oil. Although there are many ideas about the source rock of naphthalene therapeutic oil, this issue remains open among researchers. In this study, we suggest that the source rock of Naftalan oil generated from Eocene deposits based on the biomarker analysis (the 18α (H) oleanane biomarker and the ratio of diasteranes to regular steranes) of the studied oil and the maturity indicators of the Eocene and the Maikop rock samples in the Middle Kura depression.
