A process for geo-sequestration of a water-soluble fluid includes selection of a target water-laden geological formation bounded by an upper formation of low permeability, providing an injection well into the formation and injecting the fluid into the injection well under conditions of temperature, pressure and density contrast selected to cause the fluid to enter the formation and rise within the formation. This generates a density-driven convection current of formation water which promotes enhanced mixing of the water-soluble fluid with formation water.
L'invention porte sur un procédé pour la géo-séquestration d'un fluide hydrosoluble comprenant la sélection d'une formation géologique chargée d'eau cible limitée par une formation supérieure de faible perméabilité, la formation d'un puits d'injection dans la formation et l'injection du fluide dans le puits d'injection dans des conditions de température, de pression et de différence de densité choisies pour faire entrer le fluide dans la formation et monter à l'intérieur de la formation. Ceci produit un courant de convection d'eau de formation entraîné par la densité qui favorise un mélange accru du fluide hydrosoluble avec l'eau de formation.
