Abstract

A completion string can have an outer surface and an inner surface, a first fluid passageway being defined between the outer surface and the inner surface. The inner surface can define an inner region of the completion string and can have a recess that is sized to receive a sleeve that is moveable between an open position and a closed position. The inner region can be sized to receive a work string at a position at which a surface of the work string cooperates with the sleeve and the inner surface of the completion string to define a first chamber on a side of the sleeve, the first chamber being hydraulically sealed by a plurality of sealing elements. The work string can define a second fluid passageway to provide fluid communication with the first chamber.
