Abstract

De manière générale, on décrit un procédé dévacuation par gravité qui sert à récupérer lhuile visqueuse dun réservoir souterrain. Le procédé comprend linjection dune composition de mobilisation qui comprend de la vapeur et un diluant au travers dun puits dinjection dans le réservoir pour mobiliser lhuile visqueuse. La composition de mobilisation est alternée entre un premier diluant à un rapport de volume de vapeur (DSR1) de 0,05 à 0,5 et un second diluant à un rapport de volume de vapeur (DSR2) de 0 à 0,3. Le DSR1 est supérieur dau moins 0,05 à DSR2. Le procédé comprend également la production de lhuile visqueuse et dau moins une fraction de la composition de mobilisation du réservoir au travers du puits de production.
