Claim 6:
7. An assembly for cementing tubing in a wellbore with cement and for testing the tubing with applied pressure, the assembly comprising:
a tool disposed on the tubing and having an uphole end and a downhole end, the tool defining a flow bore therethrough;
an insert disposed in the flow bore and having a first seat, the insert being held in a first position by a releasable connection to the tool and being movable in the flow bore from the first position in response to release of the releasable connection;
a second seat disposed in the flow bore of the tool uphole of the insert;
a wiper plug deployable down the tubing, a portion of the wiper plug being configured to pass through the second seat and being configured to engage with the first seat of the insert, the wiper plug engaged with the first seat of the insert in the first position being configured to prevent a first application of the applied pressure through the flow bore, the insert with the engaged wiper plug being movable from the first position in response to the first application of the applied pressure releasing the releasable connection; and
a collar disposed on the wiper plug and being configured to engage with the second seat in response to the movement of the insert from the first position, the collar engaged with the second seat being configured to prevent a subsequent application of the applied pressure through the flow bore, the collar being removable at least after the subsequent application, the wiper plug upon removal of the collar being configured to release from the second seat, the insert with the engaged wiper plug being movable to a second position configured to permit fluid communication through the flow bore of the tool past the insert and the wiper plug.
