==Migration method and alteration==
==Migration method and alteration==
The migration method partly determines the extent of compositional changes that occur during secondary, [[Tertiary migration|tertiary]], or remigraton. If the petroleum moves as a broad front—as would be expected for solution gas or light oil in water and perhaps for dispersed colloids or droplets—there would be a maximum probability of interactions. However, if the petroleum moved as a slug or filament, contact with elements that could alter its composition would be more limited.
