摘要：

Application of high resolution 13 C nuclear magnetic resonance (NMR) spectroscopy to characterize Cuba oil and oil-containing rock samples from Cuban basin was demonstrated. The chemical shifts of 13 C NMR functional groups for later determination the composition of the oil and rock samples were determined. The different contribution of the studied samples in the aliphatic and aromatic areas was determined. Molar fractions of primary, secondary, quaternary, tertiary, aromatic groups, aromaticity factor and the mean length of hydrocarbon chain length of aliphatic hydrocarbons were estimated. Comparative analysis on the quantitative level for all major hydrocarbon components, the aromaticity factor and the mean length of the hydrocarbon chain were carried out. (c) 2022 The Authors.
