Abstract
De manière générale, un procédé de drainage par gravité pour récupérer de lhuile visqueuse à partir dun réservoir souterrain est décrit aux présentes. Le procédé consiste : a) à injecter de la vapeur et un solvant dans le réservoir pour mobiliser lhuile visqueuse, le solvant étant à létat de vapeur, et la vapeur et le solvant sont injectés, la fraction molaire du solvant de la vapeur et du solvant combinés se situant entre 70 et 100 % de la fraction molaire du solvant azéotropique de la vapeur et du solvant tel que mesuré à la pression de fonctionnement du réservoir; et b) à produire au moins une fraction de lhuile mobilisée, du solvant et de leau.
