Abstract

La présente invention concerne une technique qui facilite la production et la perforation de fluides de puits souhaités à partir d'un réservoir souterrain. Un système de puits est déployé dans un puits de forage et comprend un outil en Y couplé à une colonne de production. L'outil en Y comporte une première branche et une seconde branche généralement à l'opposé de la colonne de production. Un tube de dérivation est couplé à la première branche et un ensemble canon de perforation s'étend en dessous de la seconde branche. L'ensemble canon de perforation est disposé de manière adjacente au tube de dérivation. De plus, l'ensemble canon de perforation comporte une pluralité de charges de perforation, par exemple des charges façonnées, orientées de sorte à créer des perforations dans une formation environnante sans perforer le tube de dérivation.
