Wellbore isolation while placing valves on production

摘要

An internal completion string is anchored within a closed casing valve of a production liner in a wellbore. The internal completion string comprises a packer and a shifting tool. The production liner comprises a casing valve having a port and a moveable member. The annulus defined between the production liner and the internal completion string is sealed, and the shifting tool is remotely operated to move the moveable member away from the port, thereby opening the casing valve.

1. A method, comprising:
anchoring an internal completion string within a plurality of casing valves of a production liner in a wellbore that extends from the Earth's surface into a subterranean formation, wherein:
the internal completion string comprises a plurality of shifting tools; andeach casing valve comprises a port and a movable member; sealing an annulus defined between the production liner and the internal completion string; and remotely operating the plurality of shifting tools to selectively open or close each casing valve without mechanically moving the internal completion string to a different location in the production liner.
