Claim 15:
16. A method, comprising:
cementing tubing in a borehole by: (i) pumping cement down a flow bore of the tubing, (ii) deploying a wiper plug down the flow bore at least behind a portion of the cement, and (iii) seating the wiper plug on a first seat disposed in a first position in the flow bore of the tubing;
moving the first seat and the wiper plug from the first position toward a second position in the flow bore with a first application of pressure down the flow bore against the seated wiper plug;
pressure testing the tubing by: (i) seating a collar disposed on the wiper plug on a second seat disposed in the flow bore uphole of the first seat, (ii) applying a second application of pressure down the flow bore, and (iii) preventing the second application of pressure through the flow bore downhole of the collar seated in the second seat; and
establishing fluid communication through the flow bore downhole of the wiper plug, the first seat, and the second seat by removing the collar from the wiper plug, releasing the first seat and the wiper plug to move to the second position in the flow bore, and bypassing the fluid communication through the flow bore around the wiper plug seated in the first seat moved to the second position.
