Abstract
A controllable, multi-zone control system is provided for controlling the inflow of fluids into a completion, e.g. a lateral completion, at a plurality of well zones. According to an embodiment, flow control devices are distributed along the completion and a control module is positioned between the flow control devices, e.g. in a middle region of the completion. The control module is supplied with hydraulic actuating fluid and is electrically controllable to enable selective distribution of the hydraulic actuating fluid to selected flow control devices. The control module may be controlled via electric signals, thus controlling distribution of hydraulic actuating fluid under pressure to selected flow control devices so as to shift the selected flow control devices to a desired open or closed flow position.
