  • Downhole well completion system
    Patent number: 11359457
    Abstract: Downhole well completion system for control of flow to or from multiple compartments (1a,1b,1c,1d) in a targeted subterranean reservoir (30), comprising a plurality of interval control valves (2) connected in series forming a downhole string (24), said interval control valves (2) are manipulated from surface via hydraulic control lines (4a, 4b, 4c) to open or close flowports (20) of each interval control valve (2), wherein each interval control valve (2) comprises a command module (5) connected to at least two of said hydraulic control lines (4a, 4b), a first hydraulic control line is a command line (4a) to deliver applied pressure to the command module (5), which translates hydraulic pressure signals into axial movement of an inner ratchet rod (6) that determines the position of an integral pilot valve (7), a second hydraulic control line is a common-open or common-close line (4b), to provide hydraulic power to either open or close the flowports (20) of each interval control valve (2), and the inner ratchet
