Abstract

Systems and methods for controlling flow and access in multilateral completions provide for controlling rates of flow from intersecting wellbores. 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.
