“…Urdal et al [8] classified 26 artificially weathered crude oils using four different statistical methods: SIMCA, absolute ranking, K nearest neighbor (KNN) T-test, and a statistical approach developed for identification of unknown oils by means of their fingerprint data. Classification of crude oils based on the asphaltene aggregation was reported using high-pressure NIR spectroscopy.…”

Traditional methods of well surveillance, mainly test separator units, suffer from their inherent constraints, including expensive costs. The objective of this approach is to classify the oil samples taken from individual wells by source and type. The novelties of this work are utilizing the applied aspects of spectroscopy in petroleum upstream engineering, replacing traditional test methods, improving the confidence of tests, and recognizing multisource streams. The weighed sum method was used to correlate the Fourier transform infrared (FTIR) spectra taken from samples of Iranian offshore oil wells. The experimental results and the field data revealed that the present approach is appropriate for precocious, quick, and reliable surveillance of individual oil wells located in an oil field. The model was supported by thermogravimetric experiments and has accurately predicted the productivity of oil wells with respect to current expensive techniques since 2010.

“…The ratios nC17/pristane and nC18/phytane have frequently been applied in studies of biodegradation, because of the much lower susceptibility of branched alkanes toward degradation (6,7). The ratios of 3-methylphenanthrene (3-MP) versus 2-methylphenanthrene (2-MP) and 4-methyldibenzothiophene (4-MDBT) versus 2-/3-methyldibenzothiophene (2-/3-MDBT), have to some extent been applied in studies of biodegradation (8,9).…”

“…These differences collectively indicate that these oils' source rocks had varying proportions of marine and terrestrial organic matter and had expelled oil at different heating conditions. This situation, for example, as might exist for a mystery oil spill in an offshore producing area where genetically similar crude oils are being produced from different production platforms, has led to the development of numerically or statistically based analysis of crude oils' primary (genetic) fingerprinting data in efforts to more quantitatively determine the degree of correlation between spill oils and candidate sources (e.g., Urdal et al, 1986;Stout et al, 2001;Daling et al, 2002;and Chapters 7 and 9 herein). However, it should be clear that such differences will provide a strong basis to positively or negatively correlate a spilled crude oil to its candidate sources and to recognize any contribution to potentially impacted sediments or biota.…”
