Abstract: A technique includes running a seat assembly on a conveyance line into a tubing string, which has previously been installed in a well. The seat assembly includes a seat, which is adapted to receive an untethered object. The technique includes attaching the seat assembly to the string at a location downhole in the well; receiving the object to create a fluid barrier; and diverting fluid using the fluid barrier.

Abstract: A technique includes installing a tubing string having a toe initiator valve in a wellbore; and opening the toe initiator valve to establish fluid communication between an interior of the string and a region outside of the string. The technique includes using the fluid communication established by the open toe initiator valve to communicate a degradable object downhole to land in a seat of the string; and performing a downhole operation using a fluid barrier resulting from the landed object.
