Abstract
A technique provides for stimulating or otherwise treating multiple intervals/zones of a well by controlling flow of treatment fluid via a plurality of flow control devices. The flow control devices are provided with internal profiles and flow through passages. Hydraulic darts are designed for selective engagement with the internal profiles of specific flow control devices, and each hydraulic dart may be moved downhole for engagement with and activation of a specific flow control device.
