Claim Text:
1. A method of treating a plurality of well zones, comprising: providing each flow control device of a plurality of flow control devices with an internal profile and a flow through passage, wherein the internal profiles are unique relative to each other; locating the plurality of flow control devices along a casing in a well bore; and selecting a plurality of mechanical darts constructed for engagement with the internal profiles of specific flow control devices of the plurality of flow control devices such that each of the mechanical darts corresponds to a different specific flow control device; mechanically pre-setting each mechanical dart for actuation immediately prior to engagement with the internal profile of the specific flow control device corresponding to the mechanical dart; dropping each mechanical dart of the plurality of mechanical darts for engagement with the internal profile of the specific flow control device corresponding to the mechanical dart; and for at least one of the dropped mechanical darts, creating a fluid barrier via engagement with the internal profile of the corresponding specific flow device for enabling a stimulation operation.
