Abstract

A completion apparatus for a wellbore includes several flow tools and an actuation mechanism. The flow tools have a piston defining first and second chambers with a housing. The chambers communicates with hydraulics so the piston are movable in response to the communicated hydraulics. A sleeve disposed in the housing is movable with the piston between first, second, and third positions. The sleeve can have a seat movable between two conditions for passing/engaging plugs. The sleeve in the first position closes off communication through the first and second ports, and the sleeve in the second position permits communication through the first port and closes off communication through the second port. The sleeve in the third position closes off communication through the first port and permits communication through the second port. The actuation mechanism is operable to communicate the hydraulics respectively with the chambers of the flow tools.
