Abstract
A method includes disposing a tubular production string in a wellbore, the string having an upper portion with inner diameter greater than the inner diameter of a lower portion of the string. A tubular insert is disposed within the production string uphole of the lower portion. Opening an upper interval control valve (ICV) on the production string permits a flow of fluids from an upper production zone through the upper ICV to the surface through an interior annular volume formed by the exterior of the tubular insert and the interior of the upper portion, and opening a lower ICV on the production string permits a flow of fluids from a lower production zone through the lower ICV to the surface through the tubular insert, simultaneously and without commingling with fluids flowing through the upper ICV.
