Spectroscopic characterization of asphaltene deposition extracted from oil wells at the southwest of Iran using Raman and FT-IR spectroscopy
Journal Title: Applied Electromagnetics - Year 2023, Vol 11, Issue 1
Abstract
Asphaltene is a component of crude oil that creates a variety of problems in the oil industry, including reservoir wettability alteration,, corrosion in the pipelines, and pore plugging. In this paper, asphaltene samples collected from four oil wells in southwest Iran were characterized using Raman spectroscopy to investigate their molecular structures. The recorded spectra were analysed using the integrated intensities of the observed G and D1 modes, utilizing Tunistra and Koenig's proposed model. The analyses result in an estimation of the aromatic sheet diameter (La) of asphaltene samples in the range of 1.3-2.5 nm. The obtained results are consistent with those previously reported for asphaltene samples from other parts of the world. Furthermore, spectroscopic studies of recorded FT-IR spectra of samples allow estimating the structural parameters of asphaltene's Aliphatic, Aromatic, Long-chain, Substitution 1, and Substitution 2 indices with average values of 0.20, 1.36, 0.056, 0.32, and 0.28, respectively.
