Regional aspects of secondary hydrocarbon migration

The factors of influence on secondary hydrocarbon migration vary on large temporal and spatial scales (Section 4.3.1). 

The secondary hydrocarbon migration system in a basin at a certain moment during its evolution can be characterized by the masses and initial composition of the petroleum hydrocarbons available for secondary migration, the three-dimensional pattern of secondary hydrocarbon migration, i.e. the directions and lengths of the hydrocarbon migration paths, the flux of
