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. Mechanical darts are designed for engagement with the internal profiles of specific flow control devices, and each mechanical dart may be moved downhole for engagement with and activation of the specific flow control device associated with that mechanical dart.

Completion method for stimulation of multiple intervals

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.

The present invention provides for high volume flow from a well. A retrievable formation isolation valve allows high volume flow through the remaining casing or tubing. Alternatively, a large bore valve configuration that is not retrieved, but remains as part of the casing, can be used. The present invention also includes methods to allow for high volume flow using retrievable isolation valves or large bore valves.

The present invention discloses apparatus and methods for perforating, completing, testing, and abandoning a wellbore in a single trip. One embodiment of the invention is a method that comprises perforating an interval within the wellbore, positioning a sand screen assembly adjacent the perforated interval, gravel packing the perforated interval, performing testing on the perforated interval, and then abandoning the well, all in a single trip in the wellbore.
