<p>A completion string for use in a wellbore includes a tubing (10) having a bore and a housing (100) providing a main bore (102) communicating with the tubing bore and further defining plural side bores (104) generally parallel to each other. A plurality of valves (30) are positioned proximal respective side bores (104) to control fluid flow. An actuator is coupled to the valves (30) to actuate the valves (30) to at least open and closed positions. The valves (30) may be part of tubular flow elements (101) mounted to the housing, each tubular flow element (101) including a bore that forms part of a respective side bore (104). Each valve (30) may include a sleeve valve or a disk valve. The housing (100) may include a side pocket mandrel.</p> |
