Title (EN) TOE CONNECTOR BETWEEN PRODUCER AND INJECTOR WELLS
(FR) RACCORD DE BASE ENTRE PUITS EN PRODUCTION ET PUITS D'INJECTION
Abstract:
(EN) Methods and systems relate to steam assisted gravity drainage (SAGD) utilizing well pairs that are at least initially in fluid communication through drilled bores toward their toe ends. At least one of a horizontal injection well and horizontal production well of such a well pair includes a hooked length toward toe ends of each other connecting said injection well and said production well. The methods and systems improve SAGD oil production, reduce SAGD start-up time and costs, and improve overall SAGD performance.
(FR) L'invention porte sur des procédés et des systèmes relatifs au drainage par gravité assisté par vapeur (SAGD) utilisant des paires de puits qui sont au moins initialement en communication fluidique par des trous forés vers leurs extrémités de base. Au moins l'un des puits, un puits d'injection horizontal et un puits de production horizontal, d'une telle paire de puits comprend une longueur en forme de crochet située vers les extrémités de base de l'autre, raccordant ainsi ledit puits d'injection et ledit puits de production. Les procédés et les systèmes améliorent la production de pétrole en SAGD, réduisent le temps et les coûts de démarrage du SAGD et améliorent les performances d'ensemble du SAGD.
