Abstract (en)
[origin: WO2014114510A2] A well completion system comprises an outer tubular skin comprising a plurality of axially distributed stimulation fluid ports for facilitating flow through a wall structure of the outer tubular skin, and an inner tubular skin located within the outer tubular skin and defining an inner annulus with the outer tubular skin, wherein the inner tubular skin comprises a plurality of axially distributed flow control ports for facilitating flow through a wall structure of the inner tubular skin. A plurality of outer packers are axially distributed along the outer surface of the outer tubular skin for establishing a plurality of isolated outer zones, and a plurality of inner packers are axially distributed along the inner annulus for establishing a plurality of isolated inner zones, wherein at least one stimulation port and at least one flow control port is located between adjacent inner packers. A first flow control arrangement is provided and is configurable from a closed configuration in which one or more of the stimulation fluid ports are at least partially blocked, to an open configuration in which one or more of the stimulation ports are open. A second flow control arrangement is provided and is operable to control flow through the flow control ports.
