data, the peculiar behavior of data points would be regarded

merely as an extensive scatter. However, comparison with the lar-

ger database of Figs. 6 and 7 allows attributing peaks of specific

gravity to the same asphaltene phase boundaries (boundary 3b is

not reproduced due to the lack of data points in the respective con-

centration range).

Fig. 7. Complex variations of specific gravity with asphaltene content for world’s

(dead) crudes. Apparent extrema are numbered in accordance with asphaltene

phase boundaries in Fig. 5.

in the limited collection of world’s (dead) crudes.
