Figure 9

Cross-plots of the ratio of the sum of hydrocarbons with less than 15 carbon atoms over the sum of hydrocarbons with more than 15 carbon atoms (C15−/C15+) versus (a) the sum of two ratios between cycloalkanes and aromatic hydrocarbons and (b) API oil gravity. Grey arrow indicates effect of water washing. For sample location, see Figure 1(c).
