Abstract
A production control system having a series of nested tubular members including at least one axial flow channel and at least two annular flow channels. At least one valve configured and positioned to control flow from each flow channel is provided.A production apparatus having a series of nested tubulars connected to one another such that at least an axial flow channel and at least two annular flow channels are formed. A valve is associated with each flow channel and is configured to independently control flow from each flow channels.A method for controlling commingling of flows from multiple zones. The method includes containing flows from different zones to individual concentric flow channels in a nested tubular arrangement and selectively commingling one or more of the flows by setting at least one valve associated with each channel to a closed position or one of an infinite number of flow positions.
