EXPANDABLE DOWNHOLE SEAT ASSEMBLY

摘要

A technique includes deploying a seat assembly into a well. The seat assembly is initially configured to be in a first stable state in which the seat assembly is radially retracted. The technique includes transitioning the seat assembly to a second stable state in which the seat assembly is radially expanded at a downhole location in the well to form a seat to receive an untethered object; receiving the untethered object in the seat of the seat assembly; and using the received object in the seat assembly to perform a downhole operation in the well.
