Abstract
A technique that is usable with a well includes deploying a seat assembly into a tubing string; releasing the seat assembly at a downhole location inside the tubing string; pumping the seat assembly to a restriction in the tubing string at a second downhole location; and using an untethered object received in a seat assembly to form an obstruction in the tubing string.
