Abstract
A technique includes deploying a seat assembly having a plurality of segments into a tubing string installed in a well and expanding the seat assembly at a downhole location in the well to secure the assembly to the tubing string and form a seat that is adapted to receive an untethered object. The technique includes receiving the untethered object in the seat of the seat assembly and using the received untethered object in the seat assembly to perform a downhole operation in the well.
