Hydrodynamic trapping can occur in saline formations that do not have a closed trap, but where fluids migrate very slowly over long distances. When CO₂ is injected into a formation, it displaces saline formation water and then migrates buoyantly upwards, because it is less dense than the water. When it reaches the top of the formation, it continues to migrate as a separate phase until it is trapped as residual CO₂ saturation or in local structural or stratigraphic traps within the sealing formation. In the longer term, significant quantities of CO₂ dissolve in the formation water and then migrate with the groundwater.  2, record 1, English, - hydrodynamic%20trapping

Si la capture du CO₂ peut être résolue à court terme mais avec un surcoût, sa séquestration nécessite le développement de recherches amont à long terme, centrées sur les géosciences : piégeage sous forme de liquide ou fluide supercritique, dissolution dans une phase fluide, piégeage hydrodynamique, sans oublier la biologie végétale (augmentation du rendement de la photosynthèse).  2, record 1, French, - pi%C3%A9geage%20hydrodynamique
