Abstract

Summary

Hydrocarbon retention and trapping is the result of a contrast between a reservoir having a low entry pressure and a seal having a much more higher entry pressure. If there is an important overpressure or if the HC column is high the hydrodynamic conditions can be close to the hydraulic fracturation criterion and there is a possible leakage which leads possibly to a secondary migration or dismigration.

This can be also used for creating a double permeability which allows trapped hydrocarbon in the source rock porous network to be recovered during additional production phases.

Then the reservoir, source rock and sealing intervals become just the same ingredients of the capture of the hydrocarbons during a more and more efficient exploitation and recovery of molecules where they are not necessary bearing in identified conventional traps.
