Patent ID: 8443906

Claim:
An apparatus for performing an operation within a wellbore with a tubular string, comprising: a tubular member having an internal profile recess adapted to be connected into the tubular string; a downhole tool having a lock dog that releasably latches to the internal profile while the downhole tool is in an engaged position; a manipulator tool having an upper end and a lower end; a fluid passage system including a bore providing a fluid passage through the manipulator tool to provide communication between the upper end and the lower end; a barrier in the bore of the manipulator tool that blocks downward flow through the bore, and is movable to open the bore to downward flow in response to a downward directed pressure differential above a selected level; an upward-facing cup seal extending circumferentially about the manipulator tool for sealingly engaging the tubular string, the upward-facing cup seal and the barrier enabling the manipulator tool to be pumped down the tubular string into engagement with the downhole tool; a grapple on the manipulator tool that secures the manipulator tool to the downhole tool when the manipulator tool engages the downhole tool; an actuator portion within the manipulator tool to release the lock dog of the downhole tool from engagement with the internal profile recess of the tubular member in response to downward fluid pressure below the selected level, which moves the grapple when the manipulator tool is in engagement with the downhole tool; a valve in the bore that blocks upward fluid flow in the bore after the barrier has moved to open the bore; and a downhole-facing cup seal on the manipulator tool, the downward-facing cup seal and the valve enabling the downhole tool to be lifted in the tubular string by the upward fluid flow in the tubular string after the manipulator tool has released the latch dog from engagement with the internal profile recess.
