Abstract
A system for controlling flow and access in multilateral completions is disclosed. The system includes a flow control sub having a single bore portion and a dual bore portion with a sleeve disposed therein. The flow control sub further includes a channel in an inner cylindrical surface, and the sleeve includes protrusions configured to engage the channel, which may be extendable. The channel provides paths for the protrusions between three different positions where two positions allow access to one or the other bore of the dual bore portion and a third position allows flow from both bores of the dual bore portion to co-mingle and enter the flow control sub. A run-in tool may be used to engage the sleeve and apply a pulling or pushing force to move the sleeve along the various channel paths to control flow through the flow control sub.
