Abstract
A system for completing a well with multiple zones of production includes a casing having a plurality of valves that are integrated therein for isolating each well zone.

Mechanisms for actuating one or more of the valves include, but are not limited to, a dart, a drop ball, a running tool, and a control line actuating system.
