Patent ID: 8534368

Claim:
A running tool for releasing a slip to secure a body to be supported in a well by the slip and for preventing the premature actuation of the slip, the running tool and work string retrievable from the well while the slip remains in the well, comprising: the slip run in the well in a radially retracted position and released downhole by the running tool to a radially expanded position to engage a downhole tubular, and thereafter is set to grip the downhole tubular; a tool mandrel having a port providing fluid communication between a running string in fluid communication with an interior of the mandrel and an actuating piston; a blocking member for closing off the port when the tool is run in the well, and for selectively opening the port to set the slip; a slip releasing member radially outward of the mandrel and axially movable relative to the mandrel to release the slip; a locking member for preventing axial movement of the slip releasing member and thereby preventing premature releasing of the slip, the locking member being axially securable relative to the mandrel when the running tool is run in the well; and the actuating piston moveable with respect to the tool mandrel when the port is opened to move the locking member and release the slip prior to setting in the well.
