Abstract

Des procédés et systèmes de démarrage dopérations fondées sur un solvant pour récupérer des hydrocarbures à partir dun réservoir enterré sont décrits. Les procédés consistent à injecter un fluide mobilisateur de démarrage comprenant un mélange de solvant à la vapeur et de faisceau dans le réservoir par lintermédiaire de colonnes de tubage de démarrage prévues dans les segments horizontaux de puits de forage dinjection et de production, à retirer la colonne de tubage de démarrage du puits de forage de production et à fournir une colonne de tubage de production comprenant un système de levage artificiel dans le puits de forage de production. Dans certains procédés, le fluide mobilisateur de démarrage comprend un mélange de solvant à la vapeur et de faisceau essentiellement azéotropique.
