Abstract

Dans le procédé d'amélioration du conditionnement des agents gazéifiants, consistant en de l'eau à l'état liquide et en un gaz contenant de l'oxygène, utilisés dans les procédés de gazéification souterraine, l'eau, préalablement à son injection dans le gisement, est mélangée à une faible dose d'agent moussant et l'eau et le gaz oxydant sont traités dans un générateur de mousse fonctionnant sous pression avant d'etre injectés conjointement dans le gisement, sous la forme d'une mousse constituant un mélange diphasique stable et homogène.
