A formation isolation valve assembly for use in a well includes first and second fluid paths (178, 180) that are coupled to at least first and second completion zones (20, 22). A first valve (116) controls fluid flow from the first zone to the first fluid path, and a second valve (116) controls fluid flow from a second zone to the second fluid path. The valves may include ball valves and sleeve valves. |
