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

Not to be confused with "stratigraphic trapping. "Structural and stratigraphic trapping(along with hydrodynamic trapping) are all types of physical trapping. A structural trap is formed by folded or fractured rocks while a stratigraphic trap is formed by changes in rock type caused by variation of the setting where rocks were deposited.  3, record 2, English, - structural%20trapping

Ne pas confondre avec «piégeage stratigraphique». Le piégeage structural et le piégeage stratigraphique (ainsi que le piégeage hydrodynamique) sont des types de piégeage physique du CO₂. Un piège structural est formé par des plis et des failles de la roche alors qu'un piège stratigraphique est formé lorsque des couches imperméables de roches sus-jacentes agissent comme des surfaces étanches au-dessus des couches perméables sous-jacentes.  3, record 2, French, - pi%C3%A9geage%20structural

It is considered that in a suitable storage site, CO₂ will be stored by physical or geochemical trapping or a combination of both. Physical trapping includes : stratigraphic trapping, when the CO₂ is held below a low-permeability seal(cap rock) ;structural trapping, where CO₂ is trapped by physical structures such as those formed by faults and folds of the rock; or hydrodynamic trapping in saline formations, where fluids migrate very slowly and the buoyant CO₂ migrates upwards to the top of the formation.  2, record 3, English, - physical%20trapping

Le piégeage physique, qui bloque la remontée du CO₂, est assuré par une couche de schiste argileux, appelée chapeau ou couverture, située au-dessus du réservoir. Les forces capillaires qui retiennent le gaz dans les espaces interstitiels de la formation peuvent aussi contribuer au piégeage physique.  2, record 3, French, - pi%C3%A9geage%20physique
