Title
(EN) WELL INJECTION AND PRODUCTION METHOD AND SYSTEM
(FR) MÉTHODE ET SYSTÈME D'INJECTION ET DE PRODUCTION DE PUITS
Abstract
(EN) A method and system for enhancing petroleum production are provided, in which petroleum is displaced from a fractured formation by selectively injecting fluid into selected fractures in the formation without injecting into the other non-selected fractures. The injected fluid flows out into the fractured formation and enhances recovery from the non-selected fractures. Petroleum is selectively collected from the non-selected fractures.
(FR) L'invention concerne une méthode et un système d'amélioration de la production de pétrole, dans lesquels du pétrole est déplacé hors d'une formation fracturée en injectant sélectivement un fluide dans des fractures sélectionnées dans la formation sans injection dans les autres fractures non sélectionnées. Le fluide injecté s'écoule dans la formation fracturée et améliore la récupération à partir des fractures non sélectionnées. Le pétrole est recueilli sélectivement des fractures non sélectionnées.
