Abstract
ABRÉGÉ Un procédé de démarrage pour la mobilisation du bitume dans une région interpuits définie entre un puits dinjection et un puits de production se situant dans un réservoir contenant du bitume. Le procédé de démarrage comprend lintroduction dun fluide de démarrage qui comprend un solvant mobilisant et non = désasphaltant fourni, dans une première proportion, dans le réservoir qui comprend du bitume par lintermédiaire du puits dinjection, la récupération de bitume mobilisé dune région interpuits par lintermédiaire du puits de production en tant que fluide de production pour former une région appauvrie en bitume qui permet une communication fluidique entre le = puits dinjection et le puits de production, et la transition, du fluide de démarrage, de la première proportion à la deuxième, cette dernière ayant une quantité réduite de solvant mobilisant et non désasphaltant par rapport au solvant mobilisant et désasphaltant comparativement à la première proportion. La première proportion du fluide de démarrage permet, avantageusement, à des asphaltènes de demeurer essentiellement solubilisés dans le bitume mobilisé. CA 3060946 2019-11-05
