Hydrocarbon composition of the fraction with 150–300 ^оС boiling point of oil from deep-water Guneshli field has been studied. The oil is characterized with light, oily, low sulphur, low-in-tar, paraffinic structure (3.7 % mass of solid paraffin), without asphaltenes.

The fraction with 250–300 ^оС boiling point has been divided into naphteno-paraffinic and aromatic hydrocarbon groups using the method of liquid elution-adsorption chromatography. The individual hydrocarbon composition of naphteno-paraffinic hydrocarbons has been studied via chromato-mass-spectroscopy and the structure-group composition of the arenes using PMR-spectroscopy, correspondingly.

Isoprenoid С₁₃–С₁₅ and С₁₈, as well as 0.54 % mass of pristane biomarkers (С₁₉) and phytane (С₂₀) biomarkers have been revealed in the composition of naphteno-paraffinic hydrocarbons. the nuclear are enriched in the paraffinic structures in the form of substituent.
