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...

In this period, a start was made on the study of fault zones. On the Gulf Coast, it had already been noticed that faults can separate oil or gas accumulations from water-bearing sands. Hubbert, in deriving the theoretical concepts of petroleum trapping, had shown that the boundary of a reservoir rock is a barrier to hydrocarbon migration because of its capillary properties (Hubbert, 1953). Observations of fault zone material showed the effect of cataclasis but also the presence of smeared-in shale. 

The two extremes, using instantaneous and cumulative phase predictions discussed above, provide only the framework for the total variability, which can be expected in the reservoir filling history studied here. Unravelling the evolution of petroleum fluid compositions in the Snorre Field through time would require a model resolution far exceeding what can be handled in reasonable computing time. The approach shown allows, however, a prediction of fluid properties, which is much closer to the natural fluid compositions than previously possible. This compositional kinetic scheme is the first of its kind to allow reasonable petroleum phase behaviour assessment in the simulation of basin evolution and hydrocarbon migration.

Hydrocarbon migration paths As discussed in the previous section, an important attribute of many basin-centred gas systems is the proximity of the source rock to the reservoir. Consequently, the migration pathway is less critical to the formation of a BCGS reservoir than in conventional petroleum systems.

Even if all of the elements described so far have been present within a sedimentary basin an accumulation will not necessarily be encountered. One of the crucial questions in prospect evaluation is about the timing of events. The deformation of strata into a suitable trap has to precede the maturation and migration of petroleum. The reservoir seal must have been intact throughout geologic time. If a leak occurred sometime in the past, the exploration well will only encounter small amounts of residual hydrocarbons. Conversely, a seal such as a fault may have developed early on in the field s history and prevented the migration of hydrocarbons into the structure.
