Abstract
An assembly having plural valves is run into a wellbore having plural zones, where each of the valves is actuatable by dropping a valve-actuating object into the corresponding valve. The valves are successively actuating, in a predetermined sequence, to an open state. The zones are successively tested after actuating corresponding valves to the open state.
