Abstract
A standard ROV/manual gate valve operating mechanism is used to move a bore selector between the production and annulus bores of a completion. The ROV operation could be via torsion or linear action. The positioning of the selector may be hydraulically linked to the functioning of retainer valves. Alternatively, the operating mechanism may be for one of the retainer valves, with a mechanical linkage for actuation of the bore selector.
