Patent ID: 7377321

Claim:
A method comprising: running an assembly having plural valves into a wellbore having plural zones, each of the valves actuatable by dropping a valve-actuating object into the corresponding valve; successively actuating, in a predetermined sequence, the valves to an open state; and successively testing the zones after actuating corresponding valves to the open state, wherein actuating each given valve to the open state comprises: dropping a corresponding valve-actuating object into the given valve; catching the valve-actuating object in the given valve; applying pressure against the valve-actuating object to move a member in the given valve to expose one or more openings of the given valve to enable fluid flow between an inner bore of the given valve and a region outside the given valve; and actuating the given valve from a first state to a second state, wherein the given valve when in the first state allows the valve-actuating object to pass through the given valve, and wherein the given valve when in the second state allows the valve-actuating object to be caught by the given valve.
