Systems and methods for controlling flow and access in multilateral completions provide for controlling rates of flow from intersecting wellbores. In a described embodiment, flow from a branch wellbore and flow from a lower parent wellbore are controlled by respective remotely actuated flow control devices interconnected in a production tubing string in the parent wellbore. Access is provided to both of the wellbores below an intersection of the wellbores.

Des systèmes et des méthodes permettant le contrôle du débit et de l'accès dans des complétions multilatérales fournissent le contrôle de taux d'écoulement de puits de forage d'intersection. Dans une réalisation décrite, un débit d'un puits secondaire et un débit d'un puits de forage parent inférieur sont contrôlés en activant à distance respectivement des dispositifs de contrôle du débit interconnectés dans une colonne de tubage dans le puits de forage parent. Un accès est fourni aux deux puits de forage en dessous d'une intersection de ceux-ci.
