Abstract: A system that is usable with a well includes a string and valve assemblies that are disposed on the string. The valve assembly includes at least one control port and at least one radial fluid communication port. The valve assembly is adapted to serially receive an untethered object deployed in the string such that receipt of the object by a valve assembly of the plurality of valve assemblies creates a fluid obstruction to cause the valve assembly to expose the at least one control port of the valve assembly; serially release the untethered object; and jointly respond to pressurization of the string to open the radial fluid communication ports.

Abstract: A wellbore servicing apparatus comprising a housing substantially defining an axial flowbore and comprising one or more ports, an expandable seat, and a sliding sleeve slidably fitted within the housing, the sliding sleeve being transitional from a first position to a second position and from the second position to a third position, wherein, in the first position, the sliding sleeve does not permit fluid communication via the one or more ports and the expandable seat is retained in a narrower, non-expanded conformation, wherein, in the second position, the sliding sleeve permits fluid communication via the one or more ports and the expandable seat is retained in a narrower, non-expanded conformation, and wherein, in the third position, the sliding sleeve does not permit fluid communication via the one or more ports and the expandable seat is allowed to expand into a wider, expanded conformation.
