A running tool (31) sets and pressure tests a bridging hanger (53) and a packoff (103) in a single trip. The running tool (31) has a stem (33), an inner body (39), and a piston (83). The inner body (39) is connected to the stem (33) so that rotation of the stem (33) relative to the inner body (39) will cause the stem (33) to move longitudinally. The piston (83) is connected to the stem (33) so that the stem (33) and piston (83) rotate and move longitudinally in unison. A piston engagement element (55) is housed in the inner body (39) and is adapted to engage the piston (83) when the bridging hanger (53) is set to prevent premature setting of the packoff (103). The piston engagement element (55) can be disengaged once the bridging hanger (53) is set, thereby allowing the piston (83) to set the packoff (103). |
