摘要：

Principal component analysis (PCA) is applied to **1**3C nuclear magnetic resonance spectra of the naphtha fraction of crude oil from wells located on the Norwegian shelf. Unsupervised PCA correlates oil samples from the same geographical area. The correlation follows from properties related to the composition of the oils, e. g. , long-chained vs. short-chained alkanes, branching, cyclization, and aromatization. Several of the major constituents present in the oils are identified.
