Apparatuses and methods to communicate with a zone below a subsurface safety valve (104, 204) independent of the position of a closure member (106) of the safety valve are disclosed. The apparatuses and methods include deploying a subsurface safety valve (104, 204) to a profile located within a string of production tubing. The subsurface safety valve (104, 204) is in communication with a surface station through an injection conduit (150,152; 250,252) and includes a bypass pathway (144, 244) to inject various fluids to a zone below.

Cette invention concerne des dispositifs et des procédés permettant de communiquer avec une soupape de sûreté souterraine (104, 204), indépendamment de la position d'un élément de fermeture (106) de ladite soupape. Ce procédé consiste à déployer une soupape de sûreté souterraine (104, 204) en direction d'un profil situé à l'intérieur d'un colonne de tubage. La soupape de sûreté souterraine (104, 204) est en communication avec une station de surface via un conduit d'injection (150,152; 250,252) et comprend un canal de contournement pour l'injection de divers fluides dans une zone située en dessous.
