Abstract
Un procédé de production dhydrocarbures à partir dun réservoir souterrain au moins partiellement recouvert par une zone de basse pression ou une zone de perte. Le procédé consiste à fournir une paire de puits à drainage par gravité au moyen de vapeur (DGMV); à fournir un puits à drainage latéral, décalé latéralement à partir de la paire de puits DGMV à lintérieur du réservoir; à amorcer le fonctionnement de la paire de puits DGMV et du puits à drainage latéral pour créer une chambre de vapeur commune à lintérieur du réservoir; à injecter de la vapeur dans la chambre de vapeur par le biais dau moins un des puits dinjection et du puits à drainage latéral et à retirer les fluides produits à partir de la chambre de vapeur par lintermédiaire dau moins un puits de production et du puits à drainage latéral; et à co-injecter sélectivement un gaz non condensable avec la vapeur dans la chambre de vapeur à une cadence sélectionnée et à réduire la pression de la chambre de vapeur pour créer ou favoriser une zone tampon de gaz non condensable entre la chambre de vapeur et la zone de basse pression ou la zone de perte.
