1. A method comprising:
deploying a string comprising a tool in a well; perforating a designated region of the tool, the perforating causing a seat of the tool to shift from a first position which the seat is adapted to allow an untethered object deployed in the string to pass through the seat to a second position in which the seat is adapted to catch the object to form a fluid barrier in the string; diverting fluid in the string using the fluid barrier; shifting another seat of the tool from a third position in which the other seat is adapted to allow another untethered object communicated through the string to pass through the other seat to a fourth position in which the other seat is adapted to catch the other object to form another fluid barrier; and diverting fluid using the other fluid barrier. |
